Condition Certain 2002-2009 model year vehicles equipped with OnStar(R) may have a condition in which the vehicle's OnStar(R) system repeatedly makes incomplete calls to OnStar(R) without the vehicle's occupant(s) input or knowledge. Customer initiated Blue Button call, Emergency calls, and Automatic Crash Notification calls will also fail to establish a data connection with the OnStar(R) Call Center. Eventually, the customer's call will connect as a voice only line and the customer will be able to talk with an OnStar(R) advisor; however, the advisor will not get crucial customer data such as vehicle identification and location. Correction Dealers/retailers are to replace the OnStar(R) module (VCIM). Vehicles Involved Involved are certain 2002-2009 model year vehicles equipped with OnStar(R), and built within these VIN breakpoints: Note: Some model years/models have only one vehicle involved. Important Dealers/retailers are to confirm vehicle eligibility prior to beginning repairs by using GMVIS (dealers/retailers using WINS) or the Investigate Vehicle History link (dealers/retailers using GWM). Not all vehicles within the above breakpoints may be involved. For dealers/retailers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided to dealers/retailers through the GM GlobalConnect Recall Reports. Dealers/retailers will not have a report available if they have no involved vehicles currently assigned. The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program. Parts Information US: OnStar(R) modules required for this program are to be obtained by contacting Autocraft Electronics via the web at www.autocraft.com, and selecting the catalog item that contains bulletin number 10037 (or PIC 4893B), or by calling 1-800-336-3998.

DO NOT ORDER ONSTAR(R) MODULES FROM GENERAL MOTORS CUSTOMER CARE AND AFTERSALES (GMCC&A;), SATURN SERVICE PARTS OPERATION (SSPO), OR THE TECHNICAL ASSISTANCE CENTER (TAC). Courtesy Transportation The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranties. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program is very important in maintaining customer satisfaction.

Please discard Corporate Bulletin Number 02-08-46-006B (Section 08 - Body and Accessories). A small number of the above-mentioned vehicles may exhibit a condition in which the vehicle reports an inaccurate location to the OnStar(R) Call Center. This condition can only be identified via a button press to the OnStar(R) Call Center by the customer. Call Center personnel will be able to identify this inaccurate location condition. Customers will then be notified through the mail by OnStar(R) if their vehicle exhibits this condition. Once this condition has been identified OnStar(R) will instruct the customer to return to the dealership to have this condition corrected. It is not necessary to reconfigure the vehicle after the following procedure. In order to correct this condition you must cycle power to the OnStar(R) system. This can be done by either removing the fuses powering the OnStar(R) system or disconnecting the OnStar(R) module (VCIM) from the vehicle. As a last resort you can disconnect the vehicle's battery. The power needs to be removed from the system for approximately 15 minutes. After completing this procedure the vehicle should be taken to an area with an unobstructed view of the sky. The vehicle should be kept running for approximately 10 minutes to allow the vehicle to reacquire the global positioning system (GPS). Then contact the OnStar(R) Call Center via the blue OnStar(R) button and ask the advisor to verify the GPS position. If the OnStar(R) advisor still has an inaccurate GPS location refer to the Navigation Systems and Cellular Communications sub-sections in the Service Manual in order to diagnose and repair the concern. If the normal diagnostics lead to module replacement you will need to contact Technical Assistance (TAC) and choose the OnStar(R) prompt. GM OnStar(R) TAC will assist in the diagnosis and if appropriate order a replacement part. Replacement parts are usually shipped out within 24 hours and a pre-paid return package label will be included for returning the faulty part. By returning the faulty part you will avoid a significant non-return core charge. Warranty Information (excluding Saab US Models) For vehicles repaired under warranty, use the table.

Please discard Corporate Bulletin Number 02-08-46-007B (Section 08 - Body & Accessories). If the vehicle currently has analog-upgradable OnStar(R) hardware, then the customer should be made aware of the digital upgrade program per the latest version of Service Bulletin # 05-08-46-006. Any analog OnStar system that is not upgraded prior to the end of 2007 will be deactivated due to the upcoming phase-out of the analog cellular network in the U.S. and Canada. If the vehicle has recently been upgraded or has had a service replacement unit installed, this bulletin may not be applicable. Certain 2001-2008 model year vehicles equipped with OnStar(R) may exhibit a condition with the Global Positioning System (GPS) that causes inaccuracies in the GPS clock. The GPS system is internal to the OnStar(R) Vehicle Interface Unit (VIU) or the Vehicle Communication Interface Module (VCIM). This inaccuracy can result in a symptom where the OnStar(R) Call Center is unable to obtain an accurate GPS signal, hands-Free Calling minutes expire prematurely and/or the inability to add Hands-Free calling minutes. Customer Notification OnStar(R) will notify the customer by mail with instructions to contact their dealership service department. Dealer Action Not all vehicles will require VIU/VCIM replacement. The GPS signal in some vehicles may be recoverable. To determine if the signal is recoverable, simply connect the Tech2(R) and using the GPS information data display option, observe the GPS date and time. If the date/time stamps are equal to a date approximately 19 years in the future, the GPS clock has exceeded its capacity and the VIU/VCIM will need to be replaced. If the date/time stamp is in the past or near future, the GPS clock has simply generated an inaccurate value and may be recoverable by performing the following power-up reset. To initiate a power-up reset, battery voltage (batt. +) must be removed from the VIU/VCIM. The preferred methods, in order, of initiating the reset are outlined below. Remove the fuse that supplies Battery positive (Batt. +) voltage to the module (refer to the applicable Service Information schematics for the appropriate fuse). The next preferred method is to remove the connector to the OnStar(R) unit that Batt + is contained. The least preferable method is to remove the negative terminal of the vehicle battery. This will not only initiate the power-up reset, but it may also result in the loss of radio presets and other stored personalization information/settings in other modules as well. After initiating the power-up reset, the GPS data will be set to the defaulted date and time and will require an acquisition of the GPS signal in order to gain the proper date and time. Acquiring the GPS signal requires running the vehicle in an open/unobstructed view of the sky. First, contact OnStar(R) Technical Support by pressing the blue button. Allow the OnStar(R) Technical Advisor to activate the GPS recovery process. This should take approximately 10 minutes.

REMINDER - Keep in mind that the time displayed on the Tech2(R) is in Greenwich Mean Time (GMT) and the offset is based on the time zones relationship to GMT. If replacement of the VIU/VCIM is necessary, you MUST reconfigure the OnStar® system. Failure to reconfigure the system will result in an additional customer visit for repair. OnStar® VIU, Generations 2 and 3, will require the technician to press the blue OnStar® button to reconfigure the vehicle with an OnStar® advisor. OnStar(R) VCIM, Generations 4-7 will require the technician to reconfigure the vehicle with the use of the TIS2WEB and SPS applications (pass thru only), along with the Tech2(R). The configuration and set-up procedure is a two-step process that must be completed step-by-step without interruption or delay in between each step. This procedure enables an automated activation without a button press by the technician to the OnStar(R) Call Center. Following this procedure, it may take up to 24 hours for all OnStar(R) services to be fully activated. How to Order Parts If the OnStar(R) GPS date/time stamp is non-recoverable and the unit needs to be replaced, dealers in the U.S. should contact Autocraft Electronics select the catalog item that contains this bulletin number. Canadian dealers should contact MASS Electronics. Dealers DO NOT need to call the GM Technical Assistance Center (TAC) for replacement approval. Autocraft Electronics and MASS Electronics will be responsible for verifying that the subject vehicle is a candidate for a replacement VIU/VCIM.

Certain aftermarket devices, when connected to the Diagnostic Link Connector, such as, but not limited to, Scan Tools, Trip Computers, Fuel Economy Analyzers and Insurance Tracking Devices, interfere with OnStar's ability to perform a diagnostic probe when requested (via a blue button call) by a subscriber. These devices also prohibit the ability to gather diagnostic and tire pressure data for a subscriber's scheduled OnStar(R) Vehicle Diagnostic (OVD) e-mail. These aftermarket devices utilize the Vehicles serial data bus to perform data requests and/or information gathering. When these devices are requesting data, OnStar(R) is designed not to interfere with any data request being made by these devices as required by OBD II regulations. The OnStar(R) advisor is unable to definitively detect the presence of these devices and will only be able to inform the caller or requester of the unsuccessful or incomplete probe and may in some cases refer the subscriber/requester to take the vehicle to a dealer for diagnosis of the concern. When performing a diagnostic check for an unsuccessful or incomplete OnStar(R) diagnostic probe, or for concerns regarding completeness of the OnStar(R) Vehicle Diagnostic (OVD) e-mail, verify that an aftermarket device was not present at the time of the requested probe. Regarding the OVD e-mail, if an aftermarket device is interfering (including a Scan Tool of any type), the e-mail will consistently display a "yellow" indication in diagnostics section for all vehicle systems except the OnStar(R) System and Tire Pressure data (not available on all vehicles) will not be displayed (i.e. section is collapsed). Successful diagnostic probes and complete OVD e-mails will resume following the removal or disconnecting of the off-board device.

A small number of the above-mentioned vehicles may exhibit a condition in which the vehicle reports an inaccurate location to the OnStar(R) Call Center. This condition can only be identified via a button press to the OnStar(R) Call Center by the customer. Call Center personnel will be able to identify this inaccurate location condition. Customers will then be notified through the mail by OnStar(R) if their vehicle exhibits this condition. Once this condition has been identified OnStar(R) will instruct the customer to return to the dealership to have this condition corrected. It is not necessary to reconfigure the vehicle after the following procedure. In order to correct this condition you must cycle power to the OnStar(R) system. This can be done by either removing the fuses powering the OnStar(R) system or disconnecting the OnStar(R) module (VCIM) from the vehicle. As a last resort you can disconnect the vehicle's battery. The power needs to be removed from the system for approximately 15 minutes. After completing this procedure the vehicle should be taken to an area with an unobstructed view of the sky. The vehicle should be kept running for approximately 10 minutes to allow the vehicle to reacquire the global positioning system (GPS). Then contact the OnStar(R) Call Center via the blue OnStar(R) button and ask the advisor to verify the GPS position. If the OnStar(R) advisor still has an inaccurate GPS location refer to the Navigation Systems and Cellular Communications sub-sections in the Service Manual in order to diagnose and repair the concern. If the normal diagnostics lead to module replacement you will need to contact Technical Assistance (TAC) and choose the OnStar(R) prompt. GM OnStar(R) TAC will assist in the diagnosis and if appropriate order a replacement part. Replacement parts are usually shipped out within 24 hours and a pre-paid return package label will be included for returning the faulty part. By returning the faulty part you will avoid a significant non-return core charge. Warranty Information (excluding Saab US Models) For vehicles repaired under warranty, use the table.

Please discard Corporate Bulletin Number 02-08-46-007B (Section 08 - Body & Accessories). If the vehicle currently has analog-upgradable OnStar(R) hardware, then the customer should be made aware of the digital upgrade program per the latest version of Service Bulletin # 05-08-46-006. Any analog OnStar system that is not upgraded prior to the end of 2007 will be deactivated due to the upcoming phase-out of the analog cellular network in the U.S. and Canada. If the vehicle has recently been upgraded or has had a service replacement unit installed, this bulletin may not be applicable. Certain 2001-2008 model year vehicles equipped with OnStar(R) may exhibit a condition with the Global Positioning System (GPS) that causes inaccuracies in the GPS clock. The GPS system is internal to the OnStar(R) Vehicle Interface Unit (VIU) or the Vehicle Communication Interface Module (VCIM). This inaccuracy can result in a symptom where the OnStar(R) Call Center is unable to obtain an accurate GPS signal, hands-Free Calling minutes expire prematurely and/or the inability to add Hands-Free calling minutes. Customer Notification OnStar(R) will notify the customer by mail with instructions to contact their dealership service department. Dealer Action Not all vehicles will require VIU/VCIM replacement. The GPS signal in some vehicles may be recoverable. To determine if the signal is recoverable, simply connect the Tech2(R) and using the GPS information data display option, observe the GPS date and time. If the date/time stamps are equal to a date approximately 19 years in the future, the GPS clock has exceeded its capacity and the VIU/VCIM will need to be replaced. If the date/time stamp is in the past or near future, the GPS clock has simply generated an inaccurate value and may be recoverable by performing the following power-up reset. To initiate a power-up reset, battery voltage (batt. +) must be removed from the VIU/VCIM. The preferred methods, in order, of initiating the reset are outlined below. Remove the fuse that supplies Battery positive (Batt. +) voltage to the module (refer to the applicable Service Information schematics for the appropriate fuse). The next preferred method is to remove the connector to the OnStar(R) unit that Batt + is contained. The least preferable method is to remove the negative terminal of the vehicle battery. This will not only initiate the power-up reset, but it may also result in the loss of radio presets and other stored personalization information/settings in other modules as well. After initiating the power-up reset, the GPS data will be set to the defaulted date and time and will require an acquisition of the GPS signal in order to gain the proper date and time. Acquiring the GPS signal requires running the vehicle in an open/unobstructed view of the sky. First, contact OnStar(R) Technical Support by pressing the blue button. Allow the OnStar(R) Technical Advisor to activate the GPS recovery process. This should take approximately 10 minutes.

REMINDER - Keep in mind that the time displayed on the Tech2(R) is in Greenwich Mean Time (GMT) and the offset is based on the time zones relationship to GMT. If replacement of the VIU/VCIM is necessary, you MUST reconfigure the OnStar® system. Failure to reconfigure the system will result in an additional customer visit for repair. OnStar® VIU, Generations 2 and 3, will require the technician to press the blue OnStar® button to reconfigure the vehicle with an OnStar® advisor. OnStar(R) VCIM, Generations 4-7 will require the technician to reconfigure the vehicle with the use of the TIS2WEB and SPS applications (pass thru only), along with the Tech2(R). The configuration and set-up procedure is a two-step process that must be completed step-by-step without interruption or delay in between each step. This procedure enables an automated activation without a button press by the technician to the OnStar(R) Call Center. Following this procedure, it may take up to 24 hours for all OnStar(R) services to be fully activated. How to Order Parts If the OnStar(R) GPS date/time stamp is non-recoverable and the unit needs to be replaced, dealers in the U.S. should contact Autocraft Electronics select the catalog item that contains this bulletin number. Canadian dealers should contact MASS Electronics. Dealers DO NOT need to call the GM Technical Assistance Center (TAC) for replacement approval. Autocraft Electronics and MASS Electronics will be responsible for verifying that the subject vehicle is a candidate for a replacement VIU/VCIM.

Certain aftermarket devices, when connected to the Diagnostic Link Connector, such as, but not limited to, Scan Tools, Trip Computers, Fuel Economy Analyzers and Insurance Tracking Devices, interfere with OnStar's ability to perform a diagnostic probe when requested (via a blue button call) by a subscriber. These devices also prohibit the ability to gather diagnostic and tire pressure data for a subscriber's scheduled OnStar(R) Vehicle Diagnostic (OVD) e-mail. These aftermarket devices utilize the Vehicles serial data bus to perform data requests and/or information gathering. When these devices are requesting data, OnStar(R) is designed not to interfere with any data request being made by these devices as required by OBD II regulations. The OnStar(R) advisor is unable to definitively detect the presence of these devices and will only be able to inform the caller or requester of the unsuccessful or incomplete probe and may in some cases refer the subscriber/requester to take the vehicle to a dealer for diagnosis of the concern. When performing a diagnostic check for an unsuccessful or incomplete OnStar(R) diagnostic probe, or for concerns regarding completeness of the OnStar(R) Vehicle Diagnostic (OVD) e-mail, verify that an aftermarket device was not present at the time of the requested probe. Regarding the OVD e-mail, if an aftermarket device is interfering (including a Scan Tool of any type), the e-mail will consistently display a "yellow" indication in diagnostics section for all vehicle systems except the OnStar(R) System and Tire Pressure data (not available on all vehicles) will not be displayed (i.e. section is collapsed). Successful diagnostic probes and complete OVD e-mails will resume following the removal or disconnecting of the off-board device.

The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: ^ The RS-232 communication cable port ^ The connection at the data link connector (DLC) ^ The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. 2. Reprogram the electronic brake control module (EBCM). Refer to SI and Service Programming System (SPS) documentation for EBCM programming instructions, if required. 3.

Service Procedure Tech 2 Legacy or J2534 Pass-Thru Programming Method for the EBCM Important: If Tech 2 Legacy or J2534 Pass-Thru programming fails, call Techline Customer Support Center (TCSC). A "Candi" module is necessary. Calibration Information CALIBRATION INFORMATION Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 9.0 for 2007 (available on 09/03/07). If you cannot access the calibration, call the Techline Customer Support Center at 1-800-828-6860 (English) or 1-800-503-3222 (French) and it will be provided. NOTICE: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use jumper cables from an additional battery. Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: ^ The RS-232 communication cable port ^ The connection at the data link connector (DLC) ^ The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. 2. Reprogram the electronic brake control module (EBCM). Refer to SI and Service Programming System (SPS) documentation for EBCM programming instructions, if required. 3.

The BCM will remain awake and cause the draw of approximately 4.1 amps. When servicing a vehicle with this concern, back out pin 1 of the connector 2 at the BCM and see if the draw goes away. If the draw goes away, check for an aftermarket accessory (Lojack, non-factory DVD system, alarm, etc.) that is improperly installed in circuit 6815.

Please discard Corporate Bulletin Number 04-06-04-054A (Section 06 - Engine/Propulsion System). The recent rise and expansion of companies selling non-GM parts and accessories has made it necessary to issue this reminder to dealers regarding GM's policy on the use and installation of these aftermarket components. When a dealer is performing a repair under the New Vehicle Limited Warranty, they are required to use only genuine GM or GM-approved parts and accessories. This applies to all warranty repairs, special policy repairs or any repairs paid for by GM. Parts and accessories advertised as being "the same" as parts manufactured by GM, but not sold through GM, do not qualify for use in warranty repairs, special policy repairs or any repairs paid for by GM. During a warranty repair, if a GM original equipment part is not available through GM Customer Care and Aftersales (GM CC&A;), ACDelco(R) distributors, other GM dealers or approved sources, the dealer is to obtain comparable, non-GM parts and clearly indicate, in detail, on the repair order the circumstances surrounding why non-GM parts were used. The dealer must give customers written notice, prior to the sale or service, that such parts or accessories are not marketed or warranted by General Motors. It should also be noted that dealers modifying new vehicles and installing equipment, parts and accessories obtained from sources not authorized by GM are responsible for complying with the National Traffic and Motor Vehicle Safety Act. Certain non-approved parts or assemblies, installed by the dealer or its agent not authorized by GM, may result in a change to the vehicle's design characteristics and may affect the vehicle's ability to conform to federal law. Dealers must fully understand that non-GM approved parts may not have been validated, tested or certified for use. This puts the dealer at risk for potential liability in the event of a part or vehicle failure. If a GM part failure occurs as the result of the installation or use of a non-GM approved part, the warranty will not be honored. A good example of non-authorized modification of vehicles is the result of an ever increasing supply of aftermarket devices available to the customer, which claim to increase the horsepower and torque of the Duramax(TM) Diesel Engines. These include the addition of, but are not limited to one or more of the following modifications: - Propane injection - Nitrous oxide injection - Additional modules (black boxes) that connect to the vehicle wiring systems - Revised engine calibrations downloaded for the engine control module - Calibration modules which connect to the vehicle diagnostic connector - Modification to the engine turbocharger waste gate Although the installation of these devices, or modification of vehicle components, can increase engine horsepower and torque, they may also negatively affect the engine emissions, reliability and/or durability. In addition, other powertrain components, such as transmissions, universal joints, drive shafts, and front/rear axle components, can be stressed beyond design safety limits by the installation of these devices. General Motors does not support or endorse the use of devices or modifications that, when installed, increase the engine horsepower and torque. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED dealer warranty claim submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM (aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed. Refer to the latest version of Bulletin 09-06-04-026 (V8 Gas Engines) or 06-06-01-007 (Duramax(TM) Diesel Engines) for more information on dealer requirements for calibration verification. These same policies apply as they relate to the use of non-GM accessories. Damage or failure from the use or installation of a non-GM accessory will not be covered under warranty. Failure resulting from the alteration or modification of the vehicle, including the cutting, welding or disconnecting of the vehicle's original equipment parts and components will void the warranty. Additionally, dealers will NOT be reimbursed or compensated by GM in the event of any legal inquiry at either the local, state or federal level that Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Technical Service Bulletins > Engine Controls - Aftermarket Accessory Usage > Page 481 results from the alteration or modification of a vehicle using non-GM approved parts or accessories. Dealers should be especially cautious of accessory companies that claim the installation of their product will not void the factory warranty. Many times these companies have even given direction on how to quickly disassemble the accessory in an attempt to preclude the manufacturer from finding out that is has been installed. Any suspect repairs should be reviewed by the Fixed Operations Manager (FOM), and in Canada by the Warranty Manager (WM) for appropriate repair direction. If it is decided that a goodwill repair is to be made on the vehicle, even with the installation of such non-GM approved components, the customer is to be made aware of General Motors position on this issue and is to sign the appropriate goodwill documentation required by General Motors. It is imperative for dealers to understand that by installing such devices, they are jeopardizing not only the warranty coverage, but also the performance and reliability of the customer's vehicle.

For Duramax(TM) diesel powered engines, refer to the latest version of Corporate Bulletin Number 08-06-04-006G. Supercede: This bulletin is being revised to add the 2011 model year. Please discard Corporate Bulletin Number 09-06-04-026A (Section 06 - Engine/Propulsion System). General Motors is identifying an increasing number of engine, transmission and catalytic converter part failures that are the result of non-GM (aftermarket) engine and transmission control calibrations being used. When alteration to the GM-released engine or transmission control calibrations occurs, it subjects powertrain and driveline components (engine , transmission, transfer case, driveshaft and rear axle) to stresses that were not tested by General Motors. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED dealer warranty claim submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM (aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed. Warranty coverage is based on the equipment and calibrations that were released on the vehicle at time of sale, or subsequently updated by GM. That's because GM testing and validation matches the calibration to a host of criteria that is essential to assure reliability, durability and emissions performance over the life of the warranty coverage and beyond. Stresses resulting from calibrations different from those tested and released by GM can damage or weaken components, leading to poor performance and or shortened life. Additionally, non-GM (aftermarket) issued engine control modifications often do not meet the same emissions performance standards as GM issued calibrations. Depending on state statutes, individuals who install engine control module calibrations that put the vehicle outside the parameters of emissions certification standards may be subject to fines and/or penalties. This bulletin outlines a procedure to identify the presence of non-GM (aftermarket) calibrations. GM recommends performing this check whenever a hard part failure is seen on internal engine or transmission components, or before an engine assembly or transmission assembly is being replaced under warranty. It is also recommended that the engine calibration verification procedure be performed whenever diagnostics indicate that catalytic converter replacement is indicated. The PQC has a process to confirm the ECM/PCM calibration is GM issued. The PQC will require a picture of the engine calibration verification screen, as outlined in this bulletin, before authorizing any V8 gas powered engine replacement. If a non-GM calibration is found and verification has taken place through GM, the remaining powertrain and driveline warranty will be blocked and notated in GMVIS and the dealership will be notified. This block prevents any UNAUTHORIZED warranty claim submission. 1. Connect the Tech 2(R) to the vehicle. 2. Go to: Diagnostics and build the vehicle. 3. Select: Powertrain. 4. Select: Engine. 5. *Select: Engine Control Module or PCM. 6. *Select: Module ID Information or I/M Information System if the Module ID Information selection is not available. 7. *If "I/M information System" was selected, it may be necessary to select "Vehicle Information" in order to display the calibration information. ‹› If the CVN information is displayed as "N/A", it will be necessary to contact the TCSC to obtain the CVN information.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 499 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 500 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 501 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 502 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 503 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 504 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 505 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 506 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 507 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing.

OBD II diagnostics monitor the system performance and a diagnostic trouble code (DTC) sets if the system performance degrades.The malfunction indicator lamp (MIL) operation and the DTC storage are dictated by the DTC type. A DTC is ranked as a Type A or Type B if the DTC is emissions related. Type C is a non-emissions related DTC.The ECM is in the engine compartment. The ECM is the control center of the engine controls system. The ECM controls the following components: - The fuel injection system - The ignition system - The emission control systems - The on-board diagnostics - The A/C and fan systems - The throttle actuation control (TAC) system The ECM constantly monitors the information from various sensors and other inputs, and controls the systems that affect the vehicle performance and the emissions. The ECM also performs diagnostic tests on various parts of the system. The ECM can recognize operational problems and alert the driver via the MIL. When the ECM detects a malfunction, the ECM stores a DTC. The condition area is identified by the particular DTC that is set. This aids the technician in making repairs. ECM Function The engine control module (ECM) can supply 5 volts or 12 volts to the various sensors or switches. This is done through pull-up resistors to the regulated power supplies within the ECM. In some cases, even an ordinary shop voltmeter will not give an accurate reading because the resistance is too low. Therefore, a DMM with at least 10 megaohms input impedance is required in order to ensure accurate voltage readings.The ECM controls the output circuits by controlling the ground or the power feed circuit through the transistors or a device called an output driver module. EEPROM The electronically erasable programmable read only memory (EEPROM) is a permanent memory that is physically part of the engine control module (ECM). The EEPROM contains program and calibration information that the ECM needs in order to control the powertrain operation.Special equipment, as well as the correct program and calibration for the vehicle, are required in order to reprogram the ECM. Data Link Connector (DLC) The data link connector (DLC) is a 16-pin connector that provides the technician a means of accessing serial data for aid in the diagnosis. This connector allows the technician to use a scan tool in order to monitor the various serial data parameters, and display the DTC information. The DLC is located inside of the drivers compartment, underneath the dash. Malfunction Indicator Lamp (MIL) The malfunction indicator lamp (MIL) is inside of the instrument panel cluster (IPC). The MIL is controlled by the engine control module (ECM) and illuminates when the ECM detects a condition that affects the vehicle emissions. ECM Service Precautions The engine control module (ECM), by design, can withstand the normal current draws that are associated with the vehicle operations. However, care must be used in order to avoid overloading any of these circuits. When testing for opens or shorts, do not ground or apply voltage to any of the ECM circuits unless the diagnostic procedure instructs you to do so. These circuits should only be tested with a DMM. Emissions Diagnosis For State I/M Programs This OBD II equipped vehicle is designed to diagnose any conditions that could lead to excessive levels of the following emissions: - Hydrocarbons (HC) - Carbon monoxide (CO) - Oxides of nitrogen (NOx) - Evaporative emission (EVAP) system losses Should this vehicles on-board diagnostic system (ECM) detect a condition that could result in excessive emissions, the ECM turns ON the malfunction indicator lamp (MIL) and stores a DTC that is associated with the condition. Aftermarket (Add-On) Electrical And Vacuum Equipment NOTE: Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Page 596 - Do not attach add-on vacuum operated equipment to this vehicle. The use of add-on vacuum equipment may result in damage to vehicle components or systems. - Connect any add-on electrically operated equipment to the vehicle's electrical system at the battery (power and ground) in order to prevent damage to the vehicle. Aftermarket, add-on, electrical and vacuum equipment is defined as any equipment installed on a vehicle after leaving the factory that connects to the vehicles electrical or vacuum systems. No allowances have been made in the vehicle design for this type of equipment. Add-on electrical equipment, even when installed to these strict guidelines, may still cause the powertrain system to malfunction. This may also include equipment not connected to the vehicle electrical system, such as portable telephones and radios. Therefore, the first step in diagnosing any powertrain condition is to eliminate all of the aftermarket electrical equipment from the vehicle. After this is done, if the problem still exists, the problem may be diagnosed in the normal manner. Electrostatic Discharge (ESD) Damage IMPORTANT: In order to prevent possible electrostatic discharge damage to the engine control module (ECM), DO NOT touch the connector pins on the ECM. The electronic components that are used in the control systems are often designed to carry very low voltage. The electronic components are susceptible to damage caused by electrostatic discharge. Less than 100 volts of static electricity can cause damage to some electronic components. There are several ways for a person to become statically charged. The most common methods of charging are by friction and by induction. An example of charging by friction is a person sliding across a car seat.Charging by induction occurs when a person with well insulated shoes stands near a highly charged object and momentarily touches ground. Charges of the same polarity are drained off leaving the person highly charged with the opposite polarity. Static charges can cause damage, therefore, it is important to use care when handling and testing electronic components. Emissions Control Information Label The underhood Vehicle Emissions Control Information Label contains important emission specifications and setting procedures. In the upper left corner is the exhaust emission information. This identifies the year, the manufacturing division of the engine, the displacement of the engine in liters, the class of the vehicle, and type of fuel metering system. There is also an illustrated emission components and vacuum hose schematic. This label is located in the engine compartment of every General Motors vehicle. If the label has been removed, it can be ordered from GM service parts operations (GMSPO). Underhood Inspection IMPORTANT: This inspection is very important and must be done carefully and thoroughly. Perform a careful underhood inspection when performing any diagnostic procedure or diagnosing the cause of an emission test failure. This can often lead to repairing a condition without further steps. Use the following guidelines when performing an inspection: - Inspect all of the vacuum hoses for correct routing, pinches, cuts, or disconnects. - Inspect any hoses that are difficult to see. - Inspect all of the wires in the engine compartment for the following conditions: Burned or chafed spots - Pinched wires - Contact with sharp edges - Contact with hot exhaust manifolds Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Page 597 Engine Control Module: Service and Repair ENGINE CONTROL MODULE REPLACEMENT NOTE: - Turn the ignition OFF when installing or removing the control module connectors and disconnecting or reconnecting the power to the control module (battery cable, powertrain control module (PCM)/engine control module (ECM)/transaxle control module (TCM) pigtail, control module fuse, jumper cables, etc.) in order to prevent internal control module damage. - Control module damage may result when the metal case contacts battery voltage. DO NOT contact the control module metal case with battery voltage when servicing a control module, using battery booster cables, or when charging the vehicle battery. - In order to prevent any possible electrostatic discharge damage to the control module, do no touch the connector pins or the soldered components on the circuit board. - Remove any debris from around the control module connector surfaces before servicing the control module. Inspect the control module connector gaskets when diagnosing or replacing the control module. Ensure that the gaskets are installed correctly. The gaskets prevent contaminant intrusion into the control module. - The replacement control module must be programmed. IMPORTANT: - It is necessary to record the remaining engine oil life. If the replacement module is not programed with the remaining engine oil life, the engine oil life will default to 100 percent. If the replacement module is not programmed with the remaining engine oil life, the engine oil will need to be changed at 5000 km (3,000 mi) from the last engine oil change. - It is necessary to record the remaining automatic transmission fluid life. If the replacement module is not programed with the remaining automatic transmission fluid life, the automatic transmission fluid life will default to 100 percent. If the replacement module is not programmed with the remaining automatic transmission fluid life, the automatic transmission fluid will need to be changed at 83000 km (50,000 mi) from the last automatic transmission fluid change. Removal Procedure 1. Using a scan tool, retrieve the percentage of remaining engine oil and the remaining automatic transmission fluid life. Record the remaining engine oil and the remaining automatic transmission fluid life. 2. Slide the engine control module (ECM) retainer rearward, disengaging the retainer from the battery shield. 3. Remove the ECM retainer from the top of the battery shield.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 617 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 618 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 619 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 621 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 622 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 623 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 624 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 625 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 626 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 644 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities.

Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1. Slide the new terminal into the correct cavity at the back of the connector. 2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire. 3.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 690 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 700 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 701 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained, small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. If the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using GM Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may be involved. For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned. -- US dealers - GM DealerWorld Recall Information -- Export dealers - sent directly to dealers The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information No parts are required for this recall. Service Procedure Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration.

The PPS consists of an electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators. Reprogram the electronic control module (ECU). Refer to the instructions below. Tech 2 Legacy or J2534 Pass-Thru programming method for the PPS Offset Reset (PPS) Important: If Tech 2 Legacy or J2534 Pass-Thru programming fails, call Techline Customer Support Center (TCSC) at 1-800-828-6860 (English) or 1-800-503-3222 (French). A "Candi" module is necessary. Calibration Information Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Center and it will be provided. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: - The RS-232 communication cable port - The connection at the data link connector (DLC) - The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Select PPS Offset Reset from the Supported Controller screen in TIS2Web. Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required.

NHTSA CAMPAIGN ID NUMBER: 07V344000 MFR'S REPORT DATE: August 06, 2007 COMPONENT: Air Bags: Frontal: Sensor/Control Module POTENTIAL NUMBER OF UNITS AFFECTED: 437 SUMMARY: Certain sport utility vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 208, "Occupant Crash Protection." In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative unrestrained small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. CONSEQUENCE: Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. This can increase the risk of injury to a seat occupant during certain crash conditions. REMEDY: Dealers will reprogram the seat's electronic control unit. The manufacturer has not yet provided an owner notification schedule for this campaign. Owners may contact Chevrolet at 1-800-630-2438 or Pontiac at 1-800-620-7668. NOTES: GM recall No. 070174.

Vehicles Involved For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided in GMinfoNet Recall Reports. Dealers will not have a report available if they have no involved vehicles currently assigned. The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information No parts are required for this recall. Service Procedure Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration. The Passenger Presence System (PPS) is used to monitor the weight and pattern of an occupant on the front outboard passenger seat and communicate the status to the Sensing and Diagnostic module (SDM) whether to enable or suppress the deployment of the passenger airbag. The PPS consists of an electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators. Reprogram the electronic control module (ECU). Refer to the instructions below.

A "Candi" module is necessary. Calibration Information Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Centre and it will be provided. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use jumper cables from an additional battery. Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: - The RS-232 communication cable port - The connection at the data link connector (DLC) - The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required.

NHTSA CAMPAIGN ID NUMBER: 07V344000 MFR'S REPORT DATE: August 06, 2007 COMPONENT: Air Bags: Frontal: Sensor/Control Module POTENTIAL NUMBER OF UNITS AFFECTED: 437 SUMMARY: Certain sport utility vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 208, "Occupant Crash Protection." In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative unrestrained small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. CONSEQUENCE: Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. This can increase the risk of injury to a seat occupant during certain crash conditions. REMEDY: Dealers will reprogram the seat's electronic control unit. The manufacturer has not yet provided an owner notification schedule for this campaign. Owners may contact Chevrolet at 1-800-630-2438 or Pontiac at 1-800-620-7668. NOTES: GM recall No. 070174.

The driver information center (DIC), if equipped, will also display a SERVICE TIRE MONITOR type message. When the road tire is repaired and reinstalled in the original location, the TPM indicator icon illumination and DIC message may remain displayed until the DTC is cleared. To ensure that the TPM indicator and the DIC message are cleared after service, it is necessary to clear any TPM DTCs using a scan tool. If a scan tool is unavailable, performing the TPM relearn procedure using a TPM diagnostic tool will provide the same results. It is advised to perform the relearn procedure away from other vehicles to prevent picking up a stray sensor signal. If one or more of the TPM sensors are missing or damaged and have been replaced, then the relearn procedure must be performed.

Return rates ran as high as 60% with the TPM sensors still attached. Operational TPM sensors should not be returned to GM and are to be transferred to replacement wheels if they become necessary. Important: Operational TPM Sensors that are returned under warranty to General Motors will be charged back to the dealer.Sensors have a 10 year /150,000 mile (240,000 km) battery life, and should be transferred if one or more wheels are replaced. TPM Valve Stem / Grommet (0-ring) Replacement When the TPM sensors are transferred to new wheels you should replace the component used to seal the TPM sensor stem to the wheel. On sensors with an aluminum stem and visible nut on the outside of the wheel a replacement grommet (0-ring) should be used to assure a proper seal. The sensor retaining nut (except Aveo) should be tightened to 7 N.m (62 lb in) for all vehicles except Pontiac Vibe (4.0 N.m (35.4 lb in)). Important: ^ DO NOT overtorque the retaining nut. Notice: ^ Factory installed TPM Sensors come with plastic aluminum or nickel-plated brass stem caps. These caps should not be changed. Chrome plated steel caps may cause corrosion of aluminum valve stems due to incompatibility of the metals. On current style sensors the entire rubber stem is replaceable. The service interval on the revised TPM sensor with replaceable stem is the same as for any other traditional valve stem. Replace the stem at the time of tire replacement sensor transfer or whenever air seepage is suspected at the valve stem. When replacing the valve stem tighten the screw to 1.3 N.m (11.5 lb in). For either style of TPM sensor see the service parts guide for the correct GM part numbers to order and use.

Whenever the brake pedal is applied, the BPPS applies a variable voltage signal to the BCM through the stop lamp switch signal circuit. The BPPS calibration must be performed after the BPPS or body control module (BCM) have been serviced. The calibration procedure will set BPPS home value. This value is used by the BCM to determine the action of the driver applying the brake system and to provide this information to the vehicle subsystems via the communication bus. CALIBRATION PROCEDURE - Install a scan tool. - Turn ON the ignition, with the engine OFF. - Select Diagnostics. - Select the year. - Select the vehicle type. - Select BCM. - Select Module Setup. - Select the BPPS calibration procedure and follow the directions displayed on the screen.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1132 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1133 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1134 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1136 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1137 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1138 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1139 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1140 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1141 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1159 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities.

Continue to apply pressure and rock the cover until the second locking leg is unseated. Repeat procedure for the other side of the dress cover and remove the cover. 9. Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1163 3. Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1. Slide the new terminal into the correct cavity at the back of the connector. 2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire. 3. To assemble the connector, reverse the Terminal Removal Procedure.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1205 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1206 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1215 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1216 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1244 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1245 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1246 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1247 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1248 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1249 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1250 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1251 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1252 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1253 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible.

Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1317 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1318 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests.

Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1355 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1356 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1357 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1359 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1360 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1361 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1362 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1363 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1382 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1383 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1428 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1429 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Only the connector body is available for connectors with more than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the connector body. SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1435 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. DIAGNOSTIC FAULT INFORMATION TYPICAL SCAN TOOL DATA CIRCUIT/SYSTEM DESCRIPTION The crankshaft position (CKP) sensor circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, low reference circuit and an output signal circuit. The CKP sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 58-tooth reluctor wheel on the crankshaft. Each tooth on the reluctor wheel is spaced at 60-tooth spacing, with 2 missing teeth for the reference gap. The CKP sensor produces an ON/OFF DC voltage of varying frequency, with 58 output pulses per crankshaft revolution. The frequency of the CKP sensor output depends on the velocity of the crankshaft. The CKP sensor sends a digital signal, which represents an image of the crankshaft reluctor wheel, to the ECM as each tooth on the wheel rotates past the CKP sensor. The ECM uses each CKP signal pulse to determine crankshaft speed and decodes the crankshaft reluctor wheel reference gap to identify crankshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses CKP sensor output information to determine the camshaft relative position to the crankshaft, to control camshaft phasing, and to detect cylinder misfire. DIAGNOSTIC AIDS - Inspect the CKP sensor connector and the ECM connector for corrosion. - With a DTC set, the engine may crank for an extended period of time at start-up. CIRCUIT/SYSTEM VERIFICATION If DTC P0641 or P0651 are set diagnose those DTCs first. 1. With the ignition OFF, inspect the engine wiring harnesses carrying the CKP sensor circuits for the following conditions: - Close routing of secondary ignition wires - Close routing of aftermarket electrical equipment - Close to solenoids, motors, and relays - Correct any wire harness routing or component placement conditions, if it is determined to be a possible source of electrical interference. 2. Start the engine. Using the Live Plot function on the scan tool, select the CMP parameter. Change the minimum spec to 400 RPM, and the maximum spec to 4,000 RPM. Select the CKP sensor parameter. Change the minimum spec to 600 RPM, and the maximum spec to 3,300 RPM. 3. Observe the scan tool. 4. Quickly accelerate and release the accelerator pedal several time. Do not exceed 3,200 RPM. The graphed lines on the Live Plot display should track together across the screen. If the vehicle passes the Circuit/System Verification test, operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records data list.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1483 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1484 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1485 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1486 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1487 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1488 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1489 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1490 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1491 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire.

Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1557 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1604 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1605 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1606 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1608 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1609 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1610 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1611 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1612 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1613 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible.

Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1677 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1678 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

Removing the pigtail or the connector will affect sensor operation. Handle the oxygen sensor carefully. Do not drop the HO2S. Keep the in-line electrical connector and the louvered end free of grease, dirt, or other contaminants. Do not use cleaning solvents of any type. Do not repair the wiring, connector or terminals. Replace the oxygen sensor if the pigtail wiring, connector, or terminal is damaged. This external clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors, or terminals could result in the obstruction of the air reference and degraded sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: * Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor causing poor performance. * Do not damage the sensor pigtail and harness wires in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. * Ensure the sensor or vehicle lead wires are not bent sharply or kinked. Sharp bends or kinks could block the reference air path through the lead wire. * Do not remove or defeat the oxygen sensor ground wire, where applicable. Vehicles that utilize the ground wired sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will cause poor engine performance. * Ensure that the peripheral seal remains intact on the vehicle harness connector in order to prevent damage due to water intrusion. The engine harness may be repaired using Packard's Crimp and Splice Seals Terminal Repair Kit. Under no circumstances should repairs be soldered since this could result in the air reference being obstructed.

Remove the HO2S and visually inspect the portion of the sensor exposed to the exhaust stream in order to check for contamination. If contaminated, the portion of the sensor exposed to the exhaust stream will have a white powdery coating. Silicon contamination causes a high but false HO2S signal voltage (rich exhaust indication). The control module will then reduce the amount of fuel delivered to the engine, causing a severe driveability problem. Eliminate the source of contamination before replacing the oxygen sensor.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1717 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1718 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1719 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1721 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1722 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1723 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1724 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1725 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1726 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3.

Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1745 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1746 3.

Continue to apply pressure and rock the cover until the second locking leg is unseated. Repeat procedure for the other side of the dress cover and remove the cover. 9. Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1748 3. Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1. Slide the new terminal into the correct cavity at the back of the connector. 2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire. 3.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1790 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1791 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1839 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1840 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1841 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1843 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1844 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1845 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1846 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1847 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1848 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1866 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors.

This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1912 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1913 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1945 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1946 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1947 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1948 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1949 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1950 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1951 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1952 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1953 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1954 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2018 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2019 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

IMPORTANT: You must perform the following procedures in the order listed. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip keeping all of the wire strands intact. Open the harness by removing any tape. 2. Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. 3. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 4. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent american wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 5. Slide a section of high temperature SCT1 shrink tubing down the length of wire to be spliced. Ensure that the shrink tubing will not interfere with the splice procedure. 6. Select the proper DuraSeal splice sleeve according to the wire size.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2050 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2051 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2052 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2053 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2054 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2055 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2056 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2057 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2058 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2059 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2077 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2078 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2123 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2124 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 4. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent american wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 5. Slide a section of high temperature SCT1 shrink tubing down the length of wire to be spliced. Ensure that the shrink tubing will not interfere with the splice procedure. 6. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 7. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 8. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 9. Insert the wire into the DuraSeal splice sleeve barrel until the wire hits the barrel stop. 10. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2155 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2156 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2157 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2158 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2159 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2160 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2161 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2162 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2163 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2164 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2182 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2183 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2228 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2229 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. DIAGNOSTIC FAULT INFORMATION TYPICAL SCAN TOOL DATA CIRCUIT/SYSTEM DESCRIPTION The crankshaft position (CKP) sensor circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, low reference circuit and an output signal circuit. The CKP sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 58-tooth reluctor wheel on the crankshaft. Each tooth on the reluctor wheel is spaced at 60-tooth spacing, with 2 missing teeth for the reference gap. The CKP sensor produces an ON/OFF DC voltage of varying frequency, with 58 output pulses per crankshaft revolution. The frequency of the CKP sensor output depends on the velocity of the crankshaft. The CKP sensor sends a digital signal, which represents an image of the crankshaft reluctor wheel, to the ECM as each tooth on the wheel rotates past the CKP sensor. The ECM uses each CKP signal pulse to determine crankshaft speed and decodes the crankshaft reluctor wheel reference gap to identify crankshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses CKP sensor output information to determine the camshaft relative position to the crankshaft, to control camshaft phasing, and to detect cylinder misfire. DIAGNOSTIC AIDS - Inspect the CKP sensor connector and the ECM connector for corrosion. - With a DTC set, the engine may crank for an extended period of time at start-up. CIRCUIT/SYSTEM VERIFICATION If DTC P0641 or P0651 are set diagnose those DTCs first. 1. With the ignition OFF, inspect the engine wiring harnesses carrying the CKP sensor circuits for the following conditions: - Close routing of secondary ignition wires - Close routing of aftermarket electrical equipment - Close to solenoids, motors, and relays - Correct any wire harness routing or component placement conditions, if it is determined to be a possible source of electrical interference. 2. Start the engine. Using the Live Plot function on the scan tool, select the CMP parameter. Change the minimum spec to 400 RPM, and the maximum spec to 4,000 RPM. Select the CKP sensor parameter. Change the minimum spec to 600 RPM, and the maximum spec to 3,300 RPM. 3. Observe the scan tool. 4. Quickly accelerate and release the accelerator pedal several time. Do not exceed 3,200 RPM. The graphed lines on the Live Plot display should track together across the screen. If the vehicle passes the Circuit/System Verification test, operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records data list.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2283 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2284 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2285 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2286 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2287 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2288 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2289 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2290 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2291 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2292 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2356 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2357 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2358 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

Seat Occupant Sensor Calibration Error Subject: Airbag System - Passenger Sensing # 07174 - (08/22/2007) Models: 2007 Chevrolet Equinox 2007 Pontiac Torrent Condition General Motors has decided that certain 2007 Chevrolet Equinox and Pontiac Torrent vehicles fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) 208, Occupant Crash Protection. In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained, small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. If the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using GM Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may be involved. For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned. -- US dealers - GM DealerWorld Recall Information -- Export dealers - sent directly to dealers The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information No parts are required for this recall. Service Procedure Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration. The Passenger Presence System (PPS) is used to monitor the weight and pattern of an occupant on the front outboard passenger seat and communicate Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Restraint Systems > Seat Occupant Sensor > Component Information > Technical Service Bulletins > Recalls: > 07174 > Aug > 07 > Recall - Seat Occupant Sensor Calibration Error > Page 2404 the status to the Sensing and Diagnostic module (SDM) whether to enable or suppress the deployment of the passenger airbag. The PPS consists of an electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators. Reprogram the electronic control module (ECU).

Tech 2 Legacy or J2534 Pass-Thru programming method for the PPS Offset Reset (PPS) Important: If Tech 2 Legacy or J2534 Pass-Thru programming fails, call Techline Customer Support Center (TCSC) at 1-800-828-6860 (English) or 1-800-503-3222 (French). A "Candi" module is necessary. Calibration Information Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Center and it will be provided. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: - The RS-232 communication cable port - The connection at the data link connector (DLC) - The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Select PPS Offset Reset from the Supported Controller screen in TIS2Web. Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required.

Concerns About Safety and Alterations to the Front Passenger Seat Important ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE THE SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT AS RELEASED BY GM FOR THAT VEHICLE. DO NOT ALTER THE SEAT COVERS OR SEAT-RELATED EQUIPMENT. ANY ALTERATIONS TO SEAT COVERS OR GM ACCESSORIES DEFEATS THE INTENDED DESIGN OF THE SYSTEM. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ALTERATIONS, INCLUDING ANY WARRANTY REPAIRS INCURRED. The front passenger seat in many GM vehicles is equipped with a passenger sensing system that will turn off the right front passenger's frontal airbag under certain conditions, such as when an infant or child seat is present. In some vehicles, the passenger sensing system will also turn off the right front passenger's seat mounted side impact airbag. For the system to function properly, sensors are used in the seat to detect the presence of a properly-seated occupant. The passenger sensing system may not operate properly if the original seat trim is replaced (1) by non-GM covers, upholstery or trim, or (2) by GM covers, upholstery or trim designed for a different vehicle or (3) by GM covers, upholstery or trim that has been altered by a trim shop, or (4) if any object, such as an aftermarket seat heater or a comfort enhancing pad or device is installed under the seat fabric or between the occupant and the seat fabric. Aftermarket Seat Heaters, Custom Upholstery, and Comfort Enhancing Pads or Devices Important ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE ONLY SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT RELEASED AS GM ACCESSORIES FOR THAT VEHICLE. DO NOT USE ANY OTHER TYPE OF SEAT COVERS OR SEAT-RELATED EQUIPMENT, OR GM ACCESSORIES RELEASED FOR OTHER VEHICLE APPLICATIONS. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ACCESSORIES, INCLUDING ANY WARRANTY REPAIRS MADE NECESSARY BY SUCH USE. Many types of aftermarket accessories are available to customers, upfitting shops, and dealers. Some of these devices sit on top of, or are Velcro(R) strapped to the seat while others such as seat heaters are installed under the seat fabric. Additionally, seat covers made of leather or other materials may have different padding thickness installed that could prevent the Passenger Sensing System from functioning properly.

In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained, small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. If the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using GM Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may be involved. For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned. -- US dealers - GM DealerWorld Recall Information -- Export dealers - sent directly to dealers The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information No parts are required for this recall. Service Procedure Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration. The Passenger Presence System (PPS) is used to monitor the weight and pattern of an occupant on the front outboard passenger seat and communicate Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Restraint Systems > Seat Occupant Sensor > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Seat Occupant Sensor: > 07174 > Aug > 07 > Recall - Seat Occupant Sensor Calibration Error > Page 2428 the status to the Sensing and Diagnostic module (SDM) whether to enable or suppress the deployment of the passenger airbag. The PPS consists of an electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators. Reprogram the electronic control module (ECU). Refer to the instructions below. Tech 2 Legacy or J2534 Pass-Thru programming method for the PPS Offset Reset (PPS) Important: If Tech 2 Legacy or J2534 Pass-Thru programming fails, call Techline Customer Support Center (TCSC) at 1-800-828-6860 (English) or 1-800-503-3222 (French). A "Candi" module is necessary. Calibration Information Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Center and it will be provided. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: - The RS-232 communication cable port - The connection at the data link connector (DLC) - The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Select PPS Offset Reset from the Supported Controller screen in TIS2Web. Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required.

The driver information center (DIC), if equipped, will also display a SERVICE TIRE MONITOR type message. When the road tire is repaired and reinstalled in the original location, the TPM indicator icon illumination and DIC message may remain displayed until the DTC is cleared. To ensure that the TPM indicator and the DIC message are cleared after service, it is necessary to clear any TPM DTCs using a scan tool. If a scan tool is unavailable, performing the TPM relearn procedure using a TPM diagnostic tool will provide the same results. It is advised to perform the relearn procedure away from other vehicles to prevent picking up a stray sensor signal. If one or more of the TPM sensors are missing or damaged and have been replaced, then the relearn procedure must be performed.

Return rates ran as high as 60% with the TPM sensors still attached. Operational TPM sensors should not be returned to GM and are to be transferred to replacement wheels if they become necessary. Important: Operational TPM Sensors that are returned under warranty to General Motors will be charged back to the dealer.Sensors have a 10 year /150,000 mile (240,000 km) battery life, and should be transferred if one or more wheels are replaced. TPM Valve Stem / Grommet (0-ring) Replacement When the TPM sensors are transferred to new wheels you should replace the component used to seal the TPM sensor stem to the wheel. On sensors with an aluminum stem and visible nut on the outside of the wheel a replacement grommet (0-ring) should be used to assure a proper seal. The sensor retaining nut (except Aveo) should be tightened to 7 N.m (62 lb in) for all vehicles except Pontiac Vibe (4.0 N.m (35.4 lb in)). Important: ^ DO NOT overtorque the retaining nut. Notice: ^ Factory installed TPM Sensors come with plastic aluminum or nickel-plated brass stem caps. These caps should not be changed. Chrome plated steel caps may cause corrosion of aluminum valve stems due to incompatibility of the metals. On current style sensors the entire rubber stem is replaceable. The service interval on the revised TPM sensor with replaceable stem is the same as for any other traditional valve stem. Replace the stem at the time of tire replacement sensor transfer or whenever air seepage is suspected at the valve stem. When replacing the valve stem tighten the screw to 1.3 N.m (11.5 lb in). For either style of TPM sensor see the service parts guide for the correct GM part numbers to order and use.

When dismounting and mounting tires, care must be taken when breaking the bead loose from the wheel. If the tire machines bead breaking fixture is positioned too close to the tire pressure sensor, as the tire bead breaks away from the wheel it may be forced into, or catch on the edge of the tire pressure sensor. This can damage the sensor and require the sensor to be replaced. Care must also be taken when transferring the tire bead to the other side of the wheel rim. As the tire machine rotates and the tire bead is stretched around the wheel rim, the bead can come in contact with the sensor if it is not correctly positioned in relation to the mounting/dismounting head prior to tire mounting/dismounting. This can also cause sensor damage requiring replacement. Procedure Notice: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result. Notice: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel. 1. Remove the valve core from the valve stem. 2. Deflate the tire completely. Important: Rim-clamp European-type tire changers are recommended. 3. Use the tire changer in order to remove the tire from the wheel. Follow steps 4-7 to remove the tire from the wheel. 4. When separating the tire bead from the wheel position the bead breaking fixture 90, 180 and 270 degrees from the valve stem. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Sensors and Switches > Sensors and Switches - Steering and Suspension > Sensors and Switches - Wheels and Tires > Tire Pressure Sensor > Component Information > Technical Service Bulletins > TPMS System - Service And Re-Learning Sensor IDs > Page 2480 5. Position the wheel and tire so the valve stem is situated at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the outer tire bead up and over the mounting/dismounting head. 6. Position the wheel and tire so that the valve stem is situated again at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the inner tire bead up and over the mounting/dismounting head. 7. Remove all residual liquid sealant from the inside of the tire and wheel surfaces. If any tire sealant is noted upon tire dismounting on vehicles equipped with TPM replace the tire pressure sensor. 8. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats. Important: If bead seat corrosion has been identified as an air loss concern on the wheel being worked on, refer to GM Service Bulletin # 08-03-10-006 for additional information on correcting the leak. 9. Apply GM P/N 12345884 (in Canada, P/N 5728223) or equivalent to the tire bead and the wheel rim.

Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim. 11. Position the rim so that the valve stem (1) is situated at the 3 o'clock position relative to the head (2). This will protect the sensor when the bottom bead seats. 12. After the bottom bead is on the wheel, reposition the wheel and tire so that the valve stem is situated at the 9 o'clock position relative to the head. This will protect the sensor while mounting the tire bead to the outside of the wheel.

Use the tire changer in order to install the tire to the wheel. Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, lubricate the beads and reinflate. Overinflating may cause the bead to break and cause serious personal injury. Important: Allowable bead seating pressure is 345 kPa (50 psi) on Extended Mobility Tires. 14. Inflate the tire until it passes the bead humps. Be sure that the valve core is not installed at this time. 15. Install the valve core to the valve core stem. 16. Inflate the tire to the proper air pressure. 17. Ensure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.

For your convenience, this bulletin updates and centralizes all of GM's Standard Wheel Alignment Service Procedures, Policy Guidelines and bulletins on wheel alignment warranty service. Important PLEASE FAMILIARIZE YOURSELF WITH THESE UPDATES BEFORE PERFORMING YOUR NEXT GM WHEEL ALIGNMENT SERVICE. The following five (5) key steps are a summary of this bulletin and are REQUIRED in completing a successful wheel alignment service. 1. Verify the vehicle is in an Original Equipment condition for curb weight, tires, wheels, suspension and steering configurations. Vehicles modified in any of these areas are not covered for wheel alignment warranty. 2. Review the customer concern relative to "Normal Operation" definitions. 3. Verify that vehicle is within the "Mileage Policy" range. 4. Document wheel alignment warranty claims appropriately for labor operations E2000 and E2020. The following information must be documented or attached to the repair order: - Customer concern in detail - What corrected the customer concern? - If a wheel alignment is performed: - Consult SI for proper specifications. - Document the "Before" AND "After" wheel alignment measurements/settings. - Completed "Wheel Alignment Repair Order Questionnaire" (form attached to this bulletin) 5. Use the proper wheel alignment equipment (preferred with print-out capability), process and the appropriate calibration maintenance schedules. Important If it is determined that a wheel alignment is necessary under warranty, use the proper labor code for the repair. E2000 for Steering Wheel Angle and/or Front Toe set or E2020 for Wheel Alignment Check/Adjust includes Caster, Camber and Toe set (Wheel alignment labor time for other component repairs is to be charged to the component that causes a wheel alignment operation.). The following flowchart is to help summarize the information detailed in this bulletin and should be used whenever a wheel alignment is performed. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Steering/Suspension - Wheel Alignment Specifications > Page 2550 Verify Original Equipment Condition of the Vehicle - Verify that Original Equipment Tires and Wheels or Official GM Accessory Tires and Wheels are on the vehicle. - Verify that aftermarket suspension "Lift" or "Lowering" Kits or other suspension alterations have NOT been done to the vehicle. - Check for accidental damage to the vehicle; for example, severe pothole or curb impacts, collision damage that may have affected the wheel alignment of the vehicle; e.g., engine cradles, suspension control arms, axles, wheels, wheel covers, tires may show evidence of damage/impact. - Check to be sure vehicle has seen "Normal Use" rather than abuse; e.g., very aggressive driving may show up by looking at the tires and condition of the vehicle. - Check for other additional equipment items that may significantly affect vehicle mass such as large tool boxes, campers, snow plow packages (without the snowplow RPO), etc., especially in trucks and cutaway/incomplete vehicles. Significant additional mass can affect trim height and wheel alignment of the vehicle and may necessitate a customer pay wheel alignment when placed semi-permanently in the vehicle (Upfitter instructions are to realign the vehicle after placement of these types of items. (This typically applies to trucks and incomplete vehicles that can be upfit with equipment such as the above.) Customer Concerns, "Normal Operation" Conditions and "Mileage Policy" Possible Concerns The following are typical conditions that may require wheel alignment warranty service: 1. Lead/Pull: defined as "at a constant highway speed on a typical straight road, the amount of effort required at the steering wheel to maintain the vehicle's straight heading." Important Please evaluate for the condition with hands-on the steering wheel. Follow the "Vehicle Leads/Pulls" diagnostic tree located in SI to determine the cause of a lead/pull concern. Lead/Pull concerns can be due to road crown or road slope, tires, wheel alignment or even in rare circumstances a steering gear issue. Lead/pull concerns due to road crown are considered "Normal Operation" and are NOT a warrantable condition -- the customer should be advised that this is "Normal Operation." Important Some customers may comment on a "Lead/Pull" when they hold the steering wheel in a level condition. If so, this is more likely a "steering wheel angle" concern because the customer is "steering" the vehicle to obtain a "level" steering wheel. 2. Steering wheel angle to the left or right (counter-clockwise or clockwise, respectively): Defined as the steering wheel angle (clocking) deviation from "level" while maintaining a straight heading on a typical straight road. 3. Irregular or Premature tire wear: Slight to very slight "feathering" or "edge" wear on the shoulders of tires is NOT considered unusual and should even out with a tire rotation; if the customer is concerned about a "feathering" condition of the tires, the customer could be advised to rotate the tires earlier than the next scheduled mileage/maintenance interval (but no later than the next interval). Be sure to understand the customer's driving habits as this will also heavily influence the tire wear performance; tire wear from aggressive or abusive driving habits is NOT a warrantable condition. Important Slight or mild feathering, cupping, edge or heel/toe wear of tire tread shoulders is "normal" and can show up very early in a tire/vehicle service mileage; in fact, some new tires can show evidence of feathering from the factory. These issues do NOT affect the overall performance and tread life of the tire. Dealer personnel should always check the customer's maintenance records to ensure that tire inflation pressure is being maintained to placard and that the tires are being rotated (modified-X pattern) at the proper mileage intervals. Wheel alignments are NOT to be performed for the types of "Normal" Tire Feathering shown in Figures 1-4 below. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Steering/Suspension - Wheel Alignment Specifications > Page 2551 Figure 1: Full Tread View - "NORMAL" Tire "Feathering" Wear on the Shoulder/Adjacent/Center Ribs Figure 2: Tire Shoulder View Example 1 - "NORMAL" Tire "Feathering" Wear on the Shoulder Figure 3: Tire Shoulder View Example 2 - "NORMAL" Tire "Feathering" Wear Figure 4: Detail Side View of Tire Shoulder Area - "NORMAL" Tire "Feathering" Wear Important When a wheel alignment is deemed necessary for tire wear, be sure to document on the repair order, in as much detail as possible, the severity and type of tire wear (e.g., severe center wear or severe inside or outside shoulder wear) and the position of the tire on the vehicle (RF, LF, LR, RR). Please note the customer's concern with the wear such as, noise, appearance, wear life, etc. A field product report with pictures of the tire wear condition is recommended. Refer to Corporate Bulletin Number 02-00-89-002J and #07-00-89-036C. 4. Other repairs that affect wheel alignment; e.g., certain component replacement such as suspension control arm replacement, engine cradle adjustment/replace, steering gear replacement, steering tie rod replace, suspension strut/shock, steering knuckle, etc. may require a wheel alignment. Important If other components or repairs are identified as affecting the wheel alignment, policy calls for the wheel alignment labor time to be charged to the replaced/repaired component's labor operation time rather than the wheel alignment labor operations. Important Vibration type customer concerns are generally NOT due to wheel alignment except in the rare cases; e.g., extreme diagonal wear across the tread. In general, wheel alignments are NOT to be performed as an investigation/correction for vibration concerns. "Normal Operation" Conditions Vehicle Lead/Pull Due to Road Crown or Slope: As part of "Normal Operation," vehicles will follow side-to-side or left to right road crown or slope. Be sure to verify from the customer the types of roads they are driving as they may not recognize the influence of road crown on vehicle lead/pull and steering wheel angle. If a vehicle requires significant steering effort to prevent it from "climbing" the road crown there may be an issue to be looked into further. Important Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Steering/Suspension - Wheel Alignment Specifications > Page 2552 A wheel alignment will generally NOT correct vehicles that follow the road crown since this is within "Normal Operation." Mileage Policy The following mileage policy applies for E2020 and E2000 labor operations: Note Wheel Alignment is NOT covered under the New Vehicle Limited Warranty for Express and Savana Cutaway vehicles as these vehicles require Upfitters to set the wheel alignment after completing the vehicles. - 0-800 km (0-500 mi): E2000/E2020 claims ONLY allowed with Call Center Authorization. Due to the tie down during shipping, the vehicle's suspension requires some time to reach normal operating position. For this reason, new vehicles are generally NOT to be aligned until they have accumulated at least 800 km (500 mi). A field product report should accompany any claim within this mileage range. - 801-12,000 km (501-7,500 mi): - If a vehicle came from the factory with incorrect alignment settings, any resulting off-angle steering wheel, lead/pull characteristics or the rare occurrence of excessive tire wear would be apparent early in the life of the vehicle. The following policy applies: - Vehicles 100% Factory Set/Measured for Caster/Camber/Toe - Escalade/ESV/EXT, Tahoe/Suburban, Yukon/XL/Denali, Silverado/Sierra, Express/Savana, Corvette and Colorado/Canyon: E2000/E2020 Claims: Call Center Authorization Required - All Vehicles NOT 100% Factory Set/Measured for Caster/Camber/Toe as noted above: E2000/E2020 Claims: Dealer Service Manager Authorization Required - 12,001 km and beyond (7,501 miles and beyond): During this period, customers are responsible for the wheel alignment expense or dealers may provide on a case-by case basis a one-time customer enthusiasm claim up to 16,000 km (10,000 mi). In the event that a defective component required the use of the subject labor operations, the identified defective component labor operation will include the appropriate labor time for a wheel alignment as an add condition to the component repair. Important Only one wheel alignment labor operation claim (E2000 or E2020) may be used per VIN. Warranty Documentation Requirements When a wheel alignment service has been deemed necessary, the following items will need to be clearly documented on/with the repair order: - Customer concern in detail - What corrected the customer concern? - If a wheel alignment is performed: - Consult SI for proper specifications. - Document the "Before" AND "After" wheel alignment measurements/settings. - Completed "Wheel Alignment Repair Order Questionnaire" (form attached to this bulletin) 1. Document the customer concern in as much detail as possible on the repair order and in the warranty administration system. Preferred examples: - Steering wheel is off angle in the counterclockwise direction by approximately x degrees or clocking position. - Vehicle lead/pulls to the right at approximately x-y mph. Vehicle will climb the road crown. Severe, Moderate or Slight. - RF and LF tires are wearing on the outside shoulders with severe feathering. Important In the event of a lead/pull or steering wheel angle concern, please note the direction of lead/pull (left or right) or direction of steering wheel angle (clockwise or counterclockwise) on the repair order and within the warranty claim verbatim. Important In the event of a tire wear concern, please note the position on the vehicle and where the wear is occurring on the tire; i.e., the RF tire is wearing on the inside shoulder. 2. Document the technician's findings on cause and correction of the issue. Examples: - Reset LF toe from 0.45 degrees to 0.10 degrees and RF toe from -0.25 degrees to 0.10 degrees to correct the steering wheel angle from 5 degrees counterclockwise to 0 degrees. - Reset LF camber from 0.25 degrees to -0.05 degrees to correct the cross-camber condition of +0.30 degrees to 0.00 degrees on the vehicle. - Front Sum toe was found to be 0.50 degrees, reset to 0.20 degrees. 3. Print-out the "Before" and "After" wheel alignment measurements/settings and attach them to the Repair Order or if print-out capability is not Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Steering/Suspension - Wheel Alignment Specifications > Page 2553 available, measurements may also be clearly and legibly handwritten into the Wheel Alignment Repair Order Questionnaire attached to this bulletin. 4. Attach the Wheel Alignment Repair Order Questionnaire below along with the print-out of "Before" and "After" wheel alignment measurements to the Repair Order and retain for use by GM. Wheel Alignment Equipment and Process Wheel alignments must be performed with a quality machine that will give accurate results when performing checks. "External Reference" (image-based camera technology) is preferred. Please refer to Corporate Bulletin Number 05-00-89-029B: General Motors Dealership Critical Equipment Requirements and Recommendations. Requirements: - Computerized four wheel alignment system. - Computer capable of printing before and after alignment reports. - Computer capable of time and date stamp printout. - Racking system must have jacking capability - Racking system must be capable of level to 1.6 mm (1/16 in) - Appropriate wheel stops and safety certification - Built-in turn plates and slip plates - Wheel clamps capable of attaching to 20" or larger wheels - Racking capable of accepting any GM passenger car or light duty truck - Operator properly trained and ASE-certified (U.S. only) in wheel alignment Recommendations: Racking should have front and rear jacking capability. Equipment Maintenance and Calibration: Alignment machines must be regularly calibrated in order to give correct information. Most manufacturers recommend the following: - Alignment machines with "internal reference" sensors should be checked (and calibrated, if necessary) every six months. - Alignment machines with "external reference" (image-based camera technology) should be checked (and calibrated, if necessary) once a year. - Racks must be kept level to within 1.6 mm (1/16 in). - If any instrument that is part of the alignment machine is dropped or damaged in some way, check the calibration immediately. Check with the manufacturer of your specific equipment for their recommended service/calibration schedule. Wheel Alignment Process When performing wheel alignment measurement and/or adjustment, the following steps should be taken: Preliminary Steps: 1. Verify that the vehicle has a full tank of fuel (compensate as necessary). 2. Inspect the wheels and the tires for damage. 3. Inspect the tires for the proper inflation and irregular tire wear. 4. Inspect the wheel bearings for excessive play. 5. Inspect all suspension and steering parts for looseness, wear, or damage. 6. Inspect the steering wheel for excessive drag or poor return due to stiff or rusted linkage or suspension components. 7. Inspect the vehicle trim height. 8. Compensate for frame angle on targeted vehicles (refer to Wheel Alignment Specifications in SI). Satisfactory vehicle operation may occur over a wide range of alignment angles. However, if the wheel alignment angles are not within the range of specifications, adjust the wheel alignment to the specifications. Refer to Wheel Alignment Specifications in SI. Give consideration to excess loads, such as tool boxes, sample cases, etc. Follow the wheel alignment equipment manufacturer's instructions. Measure/Adjust: Important Prior to making any adjustments to wheel alignment on a vehicle, technicians must verify that the wheel alignment specifications loaded into their wheel alignment machine are up-to-date by comparing these to the wheel alignment specifications for the appropriate model and model year in SI. Using incorrect and/or outdated specifications may result in unnecessary adjustments, irregular and/or premature tire wear and repeat customer concerns Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Steering/Suspension - Wheel Alignment Specifications > Page 2554 Important When performing adjustments to vehicles requiring a 4-wheel alignment, set the rear wheel alignment angles first in order to obtain proper front wheel alignment angles. Perform the following steps in order to measure the front and rear alignment angles: 1. Install the alignment equipment according to the manufacturer's instructions. 2. Jounce the front and the rear bumpers 3 times prior to checking the wheel alignment. 3. Measure the alignment angles and record the readings. If necessary, adjust the wheel alignment to vehicle specification and record the before and after measurements. Refer to Wheel Alignment Specifications in SI. Important Technicians must refer to SI for the correct wheel alignment specifications. SI is the only source of GM wheel alignment specifications that is kept up-to-date throughout the year. Test drive vehicle to ensure proper repair.

Alignment: Description and Operation Caster Description Caster Description Caster Description Caster is the tilting of the uppermost point of the steering axis either forward or backward, when viewed from the side of the vehicle. A backward tilt is positive (+) and a forward tilt is negative (-). Caster influences directional control of the steering but does not affect the tire wear. Caster is affected by the vehicle height, therefore it is important to keep the body at its designed height. Overloading the vehicle or a weak or sagging rear spring will affect caster. When the rear of the vehicle is lower than its designated trim height, the front suspension moves to a more positive caster. If the rear of the vehicle is higher than its designated trim height, the front suspension moves to a less positive caster. With too little positive caster, steering may be touchy at high speed and wheel returnability may be diminished when coming out of a turn. If one wheel has more positive caster than the other, that wheel will pull toward the center of the vehicle. This condition will cause the vehicle to pull or lead to the side with the least amount of positive caster. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Description and Operation > Caster Description > Page 2565 Alignment: Description and Operation Camber Description Camber Description Camber Description Camber is the tilting of the wheels from the vertical when viewed from the front of the vehicle. When the wheels tilt outward at the top, the camber is positive (+). When the wheel tilts inward at the top, the camber is negative (-). The amount of tilt is measured in degrees from the vertical. Camber settings influence the directional control and the tire wear. Too much positive camber will result in premature wear on the outside of the tire and cause excessive wear on the suspension parts. Too much negative camber will result in premature wear on the inside of the tire and cause excessive wear on the suspension parts. Unequal side-to-side camber of 1 degree or more will cause the vehicle to pull or lead to the side with the most positive camber. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Description and Operation > Caster Description > Page 2566 Alignment: Description and Operation Toe Description Toe Description Toe Description Toe is a measurement of how much the front and/or rear wheels are turned in or out from a straight-ahead position. When the wheels are turned in, toe is positive (+). When the wheels are turned out, toe is negative (-). The actual amount of toe is normally only a fraction of a degree. The purpose of toe is to ensure that the wheels roll parallel. Toe also offsets the small deflections of the wheel support system that occur when the vehicle is rolling forward. In other words, with the vehicle standing still and the wheels set with toe-in, the wheels tend to roll parallel on the road when the vehicle is moving. Improper toe adjustment will cause premature tire wear and cause steering instability. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Description and Operation > Caster Description > Page 2567 Alignment: Description and Operation Setback Description Setback Description Setback applies to both the front and the rear wheels. Setback is the amount that one wheel may be aligned behind the other wheel. Setback may be the result of a road hazard or a collision. The first clue is a caster difference from side-to-side of more than 1 degree.

Toe Description Toe Description Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Description and Operation > Caster Description > Page 2569 Toe Description Toe is a measurement of how much the front and/or rear wheels are turned in or out from a straight-ahead position.

Setback is the amount that one wheel may be aligned behind the other wheel. Setback may be the result of a road hazard or a collision. The first clue is a caster difference from side-to-side of more than 1 degree. Thrust Angles Description Thrust Angles Description Thrust Angles Description The front wheels aim or steer the vehicle. The rear wheels control tracking. This tracking action relates to the thrust angle (3). The thrust angle is the path that the rear wheels take. Ideally, the thrust angle is geometrically aligned with the body centerline (2). In the illustration, toe-in is shown on the left rear wheel, moving the thrust line (1) off center. The resulting deviation from the centerline is the thrust angle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Description and Operation > Caster Description > Page 2570 If the thrust angle is not set properly the vehicle may "dog track", the steering wheel may not be centered or it could be perceived as a bent axle. Thrust angle can be checked during a wheel alignment. Positive thrust angle means the thrust line is pointing to the right hand side (RHS) of the vehicle. Negative thrust angle means the thrust line is pointing to the left hand side (LHS) of the vehicle. If the thrust angle is out of specification, moving the axle to body relationship will change the thrust angle reading. If the vehicle is out in the Positive (+) direction-moving the RHS forward and/or LHS rearward will move the thrust angle towards zero degrees. If the vehicle is out in the Negative (-) direction-moving the RHS rearward and/or LHS forward will move the thrust angle towards zero degrees. Lead/Pull Description Lead/Pull Description At a constant highway speed on a typical straight road, lead/pull is the amount of effort required at the steering wheel to maintain the vehicle's straight path. Important: Vehicles will tend to lead/pull in the direction of the road slope as part of normal operation. Lead/pull is usually caused by the following factors: * Road slope * Variability in tire construction * Wheel alignment (front cross caster and camber) * Unbalanced steering gear * Electronic Power Steering (EPS) steering position and torque sensors not calibrated correctly, if equipped. Torque Steer Description Torque Steer Description A vehicle pulls or leads in one direction during hard acceleration. A vehicle pulls or leads in the other direction during deceleration. The following factors may cause torque steer to be more apparent on a particular vehicle: * A slightly smaller diameter tire on the right front increases a right torque lead. Inspect the front tires for differences in the brand, the construction, or the size. If the tires appear to be similar, change the front tires from side-to-side and retest the vehicle. Tire and wheel assemblies have the most significant effect on torque steer correction. * A large difference in the right and left front tire pressure * Left-to-right differences in the front view axle angle may cause significant steering pull in a vehicle. The pull will be to the side with the most downward sloping axle from the differential to the wheels. Axles typically slope downward from the differential. The slope of the transaxle pan to Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Description and Operation > Caster Description > Page 2571 level ground may be used as an indication of bias axle angles. The side with the higher transaxle pan (shown on the left side of the illustration) has the most downward sloping axle angle. Memory Steer Description Memory Steer Description Memory steer is when the vehicle wants to lead or pull in the direction the driver previously turned the vehicle. Additionally, after turning in the opposite direction, the vehicle will want to lead or pull in that direction. Wander Description Wander Description Wander is the undesired drifting or deviation of a vehicle to either side from a straight path with hand pressure on the steering wheel. Wander is a symptom of the vehicle's sensitivity to external disturbances, such as road crown and crosswind, and accentuated by poor on-center steering feel. Scrub Radius Description Scrub Radius Description Ideally, the scrub radius is as small as possible. Normally, the SAI angle and the centerline of the tire and the wheel intersect below the road surface, causing a positive scrub radius. With struts, the SAI angle is much larger than the long arm/short arm type of suspension. This allows the SAI angle to intersect the camber angle above the road surface, forming a negative scrub radius. The smaller the scrub radius, the better the directional stability. Installing aftermarket wheels that have additional offset will dramatically increase the scrub radius. The newly installed wheels may cause the centerline of the tires to move further away from the spindle. This will increase the scrub radius. A large amount of scrub radius can cause severe shimmy after hitting a bump. Four-wheel drive vehicles with large tires use a steering damper to compensate for an increased scrub radius. Scrub radius is not directly measurable by the conventional methods. Scrub radius is projected geometrically by engineers during the design phase of the suspension. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Alignment > System Information > Description and Operation > Page 2572 Alignment: Testing and Inspection Trim Height Inspection Trim Height Measurement Trim height is a predetermined measurement relating to vehicle ride height. Incorrect trim heights can cause the vehicle to bottom out over bumps, damage to the suspension components and symptoms similar to wheel alignment problems. Check the trim heights when diagnosing suspension concerns and before checking the wheel alignment. Perform the following before measuring the trim heights: * Set the tire pressure to the specifications shown on the certification label. Refer to Vehicle Certification, Tire Place Card, Anti-Theft, and Service Parts ID Label. * Check the fuel level. Add additional weight if necessary to simulate a full tank. * Make sure the passenger and rear compartments are empty, except for the spare tire. * Make sure the vehicle is on a flat and level surface, such as an alignment rack. * Check that all the vehicle doors are securely closed. * Check that the vehicle hood and rear deck lids are securely closed. * Check for installed after market accessories or modifications that could affect trim height measurement. Important: All dimensions are measured vertical to the ground. Trim height should be within ±22.0 mm (±0.87 in) to be considered correct. Measuring the Bumper Heights Use the following procedure to check the front bumper height: 1. Jounce the front and rear of the vehicle a few times and allow the suspension to settle. 2. The front bumper height measurement is taken outward 390 mm (15.35 in) from the center of the fascia to ground level. Measurements are made from the inner bumper core to ground level. Measure both sides and average the measurements. 3. Compare the measurement to the front bumper curb height specification. Refer to Trim Height Specifications. 4. If the measurement is outside of the specified range, replace the front springs. Refer to Strut, Strut Component and/or Spring Replacement. 5. Using your hands, lift the rear bumper approximately 38 mm (1.59 in). 6. Gently remove your hands and allow the vehicle to lower. 7. Using your hands, jounce the rear of the vehicle downward approximately 38 mm (1.59 in). 8. Gently remove your hands and allow the vehicle to rise. 9. The rear bumper height measurement is taken outward 530 mm (20.86 in) from the center of the fascia to ground level. Measurements are made from the inner bumper core to ground level. Measure both sides and average the measurements. 10. Compare the measurement to the rear bumper curb height specification. Refer to Trim Height Specifications. 11. If the measurement is outside of the specified range, replace the rear springs. Refer to Coil Spring Replacement.

One possible cause is wheel and tire imbalance. Another possibility is tire lead due to worn or improperly manufactured tires. Lead/pull is defined as follows: At a constant highway speed on a typical straight road, lead/pull is the amount of effort required at the steering wheel to maintain the vehicle's straight path. Lead is the vehicle deviation from a straight path on a level road without pressure on the steering wheel. Refer to Radial Tire Lead/Pull Correction in order to determine if the vehicle has a tire lead problem. See: Wheels and Tires/Testing and Inspection/Radial Tire Lead/Pull Correction Before performing any adjustment affecting wheel alignment, perform the following inspections and adjustments in order to ensure correct alignment readings: * Inspect the tires for the proper inflation and irregular tire wear. Refer to Vehicle Certification, Tire Place Card, Anti-Theft, and Service Parts ID Label and Tire Diagnosis - Irregular or Premature Wear. * Inspect the runout of the wheels and the tires. * Inspect the wheel bearings for backlash and excessive play. * Inspect the ball joints and tie rod ends for looseness or wear. * Inspect the control arms and stabilizer shaft for looseness or wear. * Inspect the steering gear for looseness at the frame.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. CIRCUIT/SYSTEM DESCRIPTION The control module enables the fuel pump relay when the ignition switch is turned ON. The control module will disable the fuel pump relay within 2 seconds unless the control module detects ignition reference pulses. The control module continues to enable the fuel pump relay as long as ignition reference pulses are detected. The control module disables the fuel pump relay within 2 seconds if ignition reference pulses cease to be detected and the ignition remains ON.The fuel system is a returnless on-demand design. The fuel pressure regulator is a part of the primary fuel tank module, eliminating the need for a return pipe from the engine. A returnless fuel system reduces the internal temperature of the fuel tank by not returning hot fuel from the engine to the fuel tank. Reducing the internal temperature of the fuel tank results in lower evaporative emissions. An electric turbine style fuel pump attaches to the primary fuel tank module inside the fuel tank. The fuel pump supplies high pressure fuel through the fuel filter, past the fuel pressure regulator, and through the fuel feed pipe to the fuel injection system. The fuel pressure regulator has a T-joint that diverts the needed fuel to the fuel rail with the unused fuel dropping back into the reservoir of the primary fuel tank module. The primary fuel tank module contains a reverse flow check valve. The check valve and the fuel pressure regulator maintain fuel pressure in the fuel feed pipe and the fuel rail in order to prevent long cranking times. The primary fuel tank module also contains a primary jet pump and a secondary jet pump. Fuel pump flow loss, caused by vapor expulsion in the pump inlet chamber, is diverted to the primary jet pump and the secondary jet pump through a restrictive orifice located on the pump cover. The primary jet pump fills the reservoir of the primary fuel tank module. The secondary jet pump creates a venturi action which causes the fuel to be drawn from the secondary side of the fuel tank, through the fuel transfer pipe, to the primary side of the fuel tank. CIRCUIT/SYSTEM VERIFICATION IMPORTANT: Inspect the fuel system for damage or external leaks before proceeding. - Verify that adequate fuel is in the fuel tank before proceeding. - The fuel pump relay may need to be commanded ON a few times in order to obtain the highest possible fuel pressure. - Before proceeding with this test review the User Manual CH 48027-5 for Safety Information and Instructions. 1. Ignition ON, engine OFF, command the fuel pump relay ON with a scan tool. You should hear the fuel pump turn ON and OFF. - If the fuel pump does not operate, refer to Fuel Pump Electrical Circuit Diagnosis. See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Component Tests and General Diagnostics 2. Ignition OFF, all accessories OFF, install a CH-48027. 3. Ignition ON, engine OFF, command the fuel pump relay ON with a scan tool. Verify the fuel pressure is between 384-425 kPa (56-62 psi) and does not decrease more than 34 kPa (5 psi) in 1 minute. CIRCUIT/SYSTEM TESTING 1. IMPORTANT: - The fuel pump relay may need to be commanded ON a few times in order to obtain the highest possible fuel pressure. - DO NOT start the engine. Ignition ON, engine OFF, command the fuel pump relay ON with a scan tool and observe the fuel pressure gage while the fuel pump is operating. Verify the fuel pressure is between 384-425 kPa (56-62 psi). If the fuel pressure is greater than the specified range, replace the fuel pump module. - If the fuel pressure is less than the specified range, test, inspect, and repair the items listed below. If all items test normal, replace the fuel pump module. - Restricted fuel feed pipe - Restricted or plugged strainer - Inspect the harness connectors and the ground circuits of the fuel pump for poor connections. 2. Verify that the fuel pressure does not decrease more than 34 kPa (5 psi) in 1 minute. 1. If the fuel pressure decreases more than the specified value, perform the following procedure: 2. Ignition OFF, relieve the fuel pressure. Refer to Fuel Pressure Relief. See: Fuel Filter/Fuel Pressure Release/Service and Repair 3. Install the J 37287 between the fuel feed pipe and the fuel rail. 4. Open the valve on the J 37287. 5. Ignition ON, command the fuel pump relay ON with a scan tool and bleed the air from the CH-48027. 6. Command the fuel pump relay ON and then OFF with a scan tool. 7. Close the valve on the J 37287. 8. Monitor the fuel pressure for 1 minute.

An incorrect spark plug causes driveability conditions. Refer to Ignition System Specifications for the correct spark plug. - Ensure that the spark plug has the correct heat range. An incorrect heat range causes the following conditions: Spark plug fouling-Colder plug - Pre-ignition causing spark plug and/or engine damage-Hotter plug SPARK PLUG INSPECTION - Inspect the terminal post (1) for damage. Inspect for a bent or broken terminal post (1). - Test for a loose terminal post (1) by twisting and pulling the post. The terminal post (1) should NOT move. - Inspect the insulator (2) for flashover or carbon tracking, soot. This is caused by the electrical charge traveling across the insulator (2) between the terminal post (1) and ground. Inspect for the following conditions: Inspect the spark plug boot for damage. - Inspect the spark plug recess area of the cylinder head for moisture, such as oil, coolant, or water. A spark plug boot that is saturated causes arcing to ground. - Inspect the insulator (2) for cracks. All or part of the electrical charge may arc through the crack instead of the electrodes (3, 4).

Measure the gap between the center electrode (4) and the side electrode (3) terminals. An excessively wide electrode gap can prevent correct spark plug operation. - Inspect for the correct spark plug torque. Insufficient torque can prevent correct spark plug operation. An over torqued spark plug, causes the insulator (2) to crack. - Inspect for signs of tracking that occurred near the insulator tip instead of the center electrode (4). - Inspect for a broken or worn side electrode (3). - Inspect for a broken, worn, or loose center electrode (4) by shaking the spark plug. A rattling sound indicates internal damage. - A loose center electrode (4) reduces the spark intensity. - Inspect for bridged electrodes (3, 4). Deposits on the electrodes (3, 4) reduce or eliminates the gap. - Inspect for worn or missing platinum pads on the electrodes (3, 4), if equipped. - Inspect for excessive fouling. - Inspect the spark plug recess area of the cylinder head for debris. Dirty or damaged threads can cause the spark plug not to seat correctly during installation. SPARK PLUG VISUAL INSPECTION - Normal operation-Brown to grayish-tan with small amounts of white powdery deposits are normal combustion by-products from fuels with additives. - Carbon fouled-Dry, fluffy, black carbon or soot caused by the following conditions: Rich fuel mixtures Leaking fuel injectors - Excessive fuel pressure - Restricted air filter element - Incorrect combustion - Reduced ignition system voltage output Weak coils - Worn ignition wires - Incorrect spark plug gap - Excessive idling or slow speeds under light loads can keep spark plug temperatures so low that normal combustion deposits may not burn off. - Deposit fouling-Oil, coolant, or additives that include substances such as silicone, very white coating, reduces the spark intensity. Most powdery deposits will not effect spark intensity unless they form into a glazing over the electrode.

Attempting to remove spark plugs from a hot engine can cause the spark plugs to seize. This can damage the cylinder head threads. - Clean the spark plug recess area before removing the spark plug. Failure to do so can result in engine damage due to dirt or foreign material entering the cylinder head, or in contamination of the cylinder head threads. Contaminated threads may prevent proper seating of the new spark plug. - Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine. 1. Remove the spark plug wires from the spark plugs. 2. Remove the spark plugs (1) from the cylinder head. INSTALLATION PROCEDURE 1. NOTE: It is important to check the gap of all new and reconditioned spark plugs before installation. Pre-set gaps may have changed during handling. Use a round wire feeler gauge to be sure of an accurate check, particularly on used plugs. Installing plugs with the wrong gap can cause poor engine performance and may even damage the engine. Gap the spark plugs to the specifications. Refer to Ignition System Specifications. 2. NOTE: - Be sure plug threads smoothly into cylinder head and is fully seated. Use a thread chaser if necessary to clean threads in cylinder head. Cross-threading or failing to fully seat spark plug can cause overheating of plug, exhaust blow-by, or thread damage. Follow the recommended torque specifications carefully. Over or under-tightening can also cause severe damage to engine or spark plug. - Refer to Component Fastener Tightening Notice.

Return rates ran as high as 60% with the TPM sensors still attached. Operational TPM sensors should not be returned to GM and are to be transferred to replacement wheels if they become necessary. Important: Operational TPM Sensors that are returned under warranty to General Motors will be charged back to the dealer.Sensors have a 10 year /150,000 mile (240,000 km) battery life, and should be transferred if one or more wheels are replaced. TPM Valve Stem / Grommet (0-ring) Replacement When the TPM sensors are transferred to new wheels you should replace the component used to seal the TPM sensor stem to the wheel. On sensors with an aluminum stem and visible nut on the outside of the wheel a replacement grommet (0-ring) should be used to assure a proper seal. The sensor retaining nut (except Aveo) should be tightened to 7 N.m (62 lb in) for all vehicles except Pontiac Vibe (4.0 N.m (35.4 lb in)). Important: ^ DO NOT overtorque the retaining nut. Notice: ^ Factory installed TPM Sensors come with plastic aluminum or nickel-plated brass stem caps. These caps should not be changed. Chrome plated steel caps may cause corrosion of aluminum valve stems due to incompatibility of the metals. On current style sensors the entire rubber stem is replaceable. The service interval on the revised TPM sensor with replaceable stem is the same as for any other traditional valve stem. Replace the stem at the time of tire replacement sensor transfer or whenever air seepage is suspected at the valve stem. When replacing the valve stem tighten the screw to 1.3 N.m (11.5 lb in). For either style of TPM sensor see the service parts guide for the correct GM part numbers to order and use.

When dismounting and mounting tires, care must be taken when breaking the bead loose from the wheel. If the tire machines bead breaking fixture is positioned too close to the tire pressure sensor, as the tire bead breaks away from the wheel it may be forced into, or catch on the edge of the tire pressure sensor. This can damage the sensor and require the sensor to be replaced. Care must also be taken when transferring the tire bead to the other side of the wheel rim. As the tire machine rotates and the tire bead is stretched around the wheel rim, the bead can come in contact with the sensor if it is not correctly positioned in relation to the mounting/dismounting head prior to tire mounting/dismounting. This can also cause sensor damage requiring replacement. Procedure Notice: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result. Notice: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel. 1. Remove the valve core from the valve stem. 2. Deflate the tire completely. Important: Rim-clamp European-type tire changers are recommended. 3. Use the tire changer in order to remove the tire from the wheel. Follow steps 4-7 to remove the tire from the wheel. 4. When separating the tire bead from the wheel position the bead breaking fixture 90, 180 and 270 degrees from the valve stem.

Position the wheel and tire so the valve stem is situated at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the outer tire bead up and over the mounting/dismounting head. 6. Position the wheel and tire so that the valve stem is situated again at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the inner tire bead up and over the mounting/dismounting head. 7. Remove all residual liquid sealant from the inside of the tire and wheel surfaces. If any tire sealant is noted upon tire dismounting on vehicles equipped with TPM replace the tire pressure sensor. 8. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats. Important: If bead seat corrosion has been identified as an air loss concern on the wheel being worked on, refer to GM Service Bulletin # 08-03-10-006 for additional information on correcting the leak. 9. Apply GM P/N 12345884 (in Canada, P/N 5728223) or equivalent to the tire bead and the wheel rim.

Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim. 11. Position the rim so that the valve stem (1) is situated at the 3 o'clock position relative to the head (2). This will protect the sensor when the bottom bead seats. 12. After the bottom bead is on the wheel, reposition the wheel and tire so that the valve stem is situated at the 9 o'clock position relative to the head. This will protect the sensor while mounting the tire bead to the outside of the wheel.

Use the tire changer in order to install the tire to the wheel. Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, lubricate the beads and reinflate. Overinflating may cause the bead to break and cause serious personal injury. Important: Allowable bead seating pressure is 345 kPa (50 psi) on Extended Mobility Tires. 14. Inflate the tire until it passes the bead humps. Be sure that the valve core is not installed at this time. 15. Install the valve core to the valve core stem. 16. Inflate the tire to the proper air pressure. 17. Ensure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.

Remove the spark plugs from all the cylinders. 4. Remove the air duct from the throttle body. 5. Block the throttle plate in the open position. 6. Measure the engine compression, using the following procedure: 1. Firmly install the compression gauge to the spark plug hole. 2. Have an assistant crank the engine through at least 4 compression strokes in the testing cylinder. 3. Record the readings on the gauge at each stroke. 4. Disconnect the gauge. 5. Repeat the compression test for each cylinder. 7. Record the compression readings from all of the cylinders. * The lowest reading should not be less than 70 percent of the highest reading. * No cylinder reading should be less than 689 kPa (100 psi). 8. The following list contains examples of the possible measurements: * When the compression measurement is normal, the compression builds up quickly and evenly to the specified compression on each cylinder. * When the compression is low on the first stroke and tends to build up on the following strokes, but does not reach the normal compression, the piston rings may be the cause. * If the compression improves considerably with the addition of three squirts of oil, the piston rings may be the cause. * When the compression is low on the first stroke and does not build up in the following strokes, the valves may be the cause. * The addition of oil does not affect the compression, the valves may be the cause. * When the compression is low on two adjacent cylinders, or coolant is present in the crankcase, the head gasket may be the cause. 9. Remove the block from the throttle plate. 10. Install the air duct to the throttle body. 11. Install the spark plugs. 12. Install the Powertrain Control Module (PCM) fuse. 13. Install the ignition fuse to the I/P fuse block.

Belt dressing causes the breakdown of the composition of the drive belt. Failure to follow this recommendation will damage the drive belt. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Drive Belt > Component Information > Technical Service Bulletins > Page 2704 Drive Belt: Description and Operation Drive Belt System Description The drive belt system consists of the following components: * The drive belt * The drive belt tensioner * The drive belt idler pulley * The crankshaft balancer pulley * The accessory drive component mounting brackets * The accessory drive components - The power steering pump, if belt driven - The generator - The A/C compressor, if equipped - The engine cooling fan, if belt driven - The water pump, if belt driven - The vacuum pump, if equipped - The air compressor, if equipped The drive belt system may use one belt or two belts. The drive belt is thin so that it can bend backwards and has several ribs to match the grooves in the pulleys. There also may be a V-belt style belt used to drive certain accessory drive components. The drive belts are made of different types of rubbers (chloroprene or EPDM) and have different layers or plys containing either fiber cloth or cords for reinforcement. Both sides of the drive belt may be used to drive the different accessory drive components. When the back side of the drive belt is used to drive a pulley, the pulley is smooth. The drive belt is pulled by the crankshaft balancer pulley across the accessory drive component pulleys. The spring loaded drive belt tensioner keeps constant tension on the drive belt to prevent the drive belt from slipping. The drive belt tensioner arm will move when loads are applied to the drive belt by the accessory drive components and the crankshaft. The drive belt system may have an idler pulley, which is used to add wrap to the adjacent pulleys. Some systems use an idler pulley in place of an accessory drive component when the vehicle is not equipped with the accessory. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Drive Belt > Component Information > Testing and Inspection > Drive Belt Chirping, Squeal, and Whine Diagnosis Drive Belt: Testing and Inspection Drive Belt Chirping, Squeal, and Whine Diagnosis Drive Belt Chirping, Squeal, and Whine Diagnosis Diagnostic Aids * A chirping or squeal noise may be intermittent due to moisture on the drive belts or the pulleys. It may be necessary to spray a small amount of water on the drive belts in order to duplicate the customers concern. If spraying water on the drive belt duplicates the symptom, cleaning the belt pulleys may be the probable solution. * If the noise is intermittent, verify the accessory drive components by varying their loads making sure they are operated to their maximum capacity. An overcharged A/C system, power steering system with a pinched hose or wrong fluid, or a generator failing are suggested items to inspect. * A chirping, squeal or whine noise may be caused by a loose or improper installation of a body or suspension component. Other items of the vehicle may also cause the noise. * The drive belts will not cause a whine noise. Test Description The numbers below refer to the step numbers on the diagnostic table. 2. The noise may not be engine related. This step is to verify that the engine is making the noise. If the engine is not making the noise do not proceed further with this table. 3. The noise may be an internal engine noise. Removing the drive belts one at a time and operating the engine for a brief period will verify the noise is related to the drive belt. When removing the drive belt the water pump may not be operating and the engine may overheat. Also DTCs may set when the engine is operating with the drive belts removed. 4. Inspect all drive belt pulleys for pilling. Pilling is the small balls or pills or it can be strings in the drive belt grooves from the accumulation of rubber dust. 6. Misalignment of the pulleys may be caused from improper mounting of the accessory drive component, incorrect installation of the accessory drive component pulley, or the pulley bent inward or outward from a previous repair. Test for a misaligned pulley using a straight edge in the pulley grooves across two or three pulleys. If a misaligned pulley is found refer to that accessory drive component for the proper installation procedure for that pulley. 10. Inspecting of the fasteners can eliminate the possibility that a wrong bolt, nut, spacer, or washer was installed. 12. Inspecting the pulleys for being bent should include inspecting for a dent or other damage to the pulleys that would prevent the drive belt from not seating properly in all of the pulley grooves or on the smooth surface of a pulley when the back side of the belt is used to drive the pulley. 14. This test is to verify that the drive belt tensioner operates properly. If the drive belt tensioner is not operating properly, proper belt tension may not be achieved to keep the drive belt from slipping which could cause a squeal noise. 15. This test is to verify that the drive belt is not too long, which would prevent the drive belt tensioner from working properly. Also if an incorrect length drive belt was installed, it may not be routed properly and may be turning an accessory drive component in the wrong direction. 16. Misalignment of the pulleys may be caused from improper mounting of the accessory drive component, incorrect installation of the accessory drive component pulley, or the pulley bent inward or outward from a previous repair. Test for a misaligned pulley using a straight edge in the pulley grooves across two or three pulleys. If a misaligned pulley is found refer to that accessory drive component for the proper installation procedure for that pulley. 17. This test is to verify that the pulleys are the correct diameter or width. Using a known good vehicle compare the pulley sizes. 19. Replacing the drive belt when it is not damaged or there is not excessive pilling will only be a temporary repair.

An extra load that is quickly applied on released by an accessory drive component may cause the drive belt to fall off the pulleys. Verify the accessory drive components operate properly. If the drive belt is the incorrect length, the drive belt tensioner may not keep the proper tension on the drive belt. Excessive wear on a drive belt is usually caused by an incorrect installation or the wrong drive belt for the application. Minor misalignment of the drive belt pulleys will not cause excessive wear, but will probably cause the drive belt to make a noise or to fall off. Excessive misalignment of the drive belt pulleys will cause excessive wear but may also make the drive belt fall off. Test Description The numbers below refer to the step numbers on the diagnostic table. 2. This inspection is to verify the condition of the drive belt. Damage may of occurred to the drive belt when the drive belt fell off. The drive belt may of been damaged, which caused the drive belt to fall off. Inspect the belt for cuts, tears, sections of ribs missing, or damaged belt plys. 4. Misalignment of the pulleys may be caused from improper mounting of the accessory drive component, incorrect installation of the accessory drive component pulley, or the pulley bent inward or outward from a previous repair. Test for a misaligned pulley using a straight edge in the pulley grooves across two or three pulleys. If a misaligned pulley is found refer to that accessory drive component for the proper installation procedure of that pulley. 5. Inspecting the pulleys for being bent should include inspecting for a dent or other damage to the pulleys that would prevent the drive belt from not seating properly in all of the pulley grooves or on the smooth surface of a pulley when the back side of the belt is used to drive the pulley. 6. Accessory drive component brackets that are bent or cracked will let the drive belt fall off. 7. Inspection of the fasteners can eliminate the possibility that a wrong bolt, nut , spacer, or washer was installed. Missing, loose, or the wrong fasteners may cause pulley misalignment from the bracket moving under load. Over tightening of the fasteners may cause misalignment of the accessory component bracket. 13. The inspection is to verify the drive belt is correctly installed on all of the drive belt pulleys. Wear on the drive belt may be caused by mis-positioning the drive belt by one groove on a pulley. 14. The installation of a drive belt that is too wide or too narrow will cause wear on the drive belt. The drive belt ribs should match all of the grooves on all of the pulleys. 15. This inspection is to verify the drive belt is not contacting any parts of the engine or body while the engine is operating. There should be sufficient clearance when the drive belt accessory drive components load varies. The drive belt should not come in contact with an engine or a body component when snapping the throttle.

Vibration from the engine operating may cause a body component or another part of the vehicle to make rumbling noise. Vibration can be caused by, but not limited to the air conditioning (A/C) system over charged, the power steering system restricted or the incorrect fluid, or an extra load on the generator. To help identify an intermittent or an improper condition, vary the loads on the accessory drive components. The drive belt may have a rumbling condition that can not be seen or felt. Sometimes replacing the drive belt may be the only repair for the symptom. If replacing the drive belt, completing the diagnostic table, and the noise is only heard when the drive belts are installed, there might be an accessory drive component with a failure. Varying the load on the different accessory drive components may aid in identifying which component is causing the rumbling noise. Test Description The numbers below refer to the step numbers on the diagnostic table. 2. This test is to verify that the symptom is present during diagnosing. Other vehicle components may cause a similar symptom. 3. This test is to verify that one of the drive belts is causing the rumbling noise or vibration. Rumbling noise may be confused with an internal engine noise due to the similarity in the description. Remove only one drive belt at a time if the vehicle has multiple drive belts. When removing the drive belts the water pump may not be operating and the engine may overheat. Also DTCs may set when the engine is operating with the drive belts removed. 4. Inspecting the drive belts is to ensure that they are not causing the noise. Small cracks across the ribs of the drive belt will not cause the noise. Belt separation is identified by the plys of the belt separating and may be seen at the edge of the belt our felt as a lump in the belt. 5. Small amounts of pilling is normal condition and acceptable. When the pilling is severe the drive belt does not have a smooth surface for proper operation. 9. Inspecting of the fasteners can eliminate the possibility that the wrong bolt, nut, spacer, or washer was installed. 11. This step should only be performed if the water pump is driven by the drive belt. Inspect the water pump shaft for being bent. Also inspect the water pump bearings for smooth operation and excessive play. Compare the water pump with a known good water pump. 12. Accessory drive component brackets that are bent, cracked, or loose may put extra strain on that accessory component causing it to vibrate.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Filters > Oil Filter, Engine > Component Information > Technical Service Bulletins > Engine - Noise/Damage Oil Filter Application Importance Oil Filter: Technical Service Bulletins Engine - Noise/Damage Oil Filter Application Importance INFORMATION Bulletin No.: 07-06-01-016B Date: July 27, 2009 Subject: Information on Internal Engine Noise or Damage After Oil Filter Replacement Models: 2010 and Prior Passenger Cars and Trucks (Including Saturn) 2010 and Prior HUMMER H2, H3 2009 and Prior Saab 9-7X Supercede: This bulletin is being updated to add model years. Please discard Corporate Bulletin Number 07-06-01-016A (Section 06 - Engine/Propulsion System). Important Engine damage that is the result of an incorrect or improperly installed engine oil filter is not a warrantable claim. The best way to avoid oil filter quality concerns is to purchase ACDelco(R) oil filters directly from GMSPO. Oil filter misapplication may cause abnormal engine noise or internal damage. Always utilize the most recent parts information to ensure the correct part number filter is installed when replacing oil filters. Do not rely on physical dimensions alone. Counterfeit copies of name brand parts have been discovered in some aftermarket parts systems. Always ensure the parts you install are from a trusted source. Improper oil filter installation may result in catastrophic engine damage. Refer to the appropriate Service Information (SI) installation instructions when replacing any oil filter and pay particular attention to procedures for proper cartridge filter element alignment. If the diagnostics in SI (Engine Mechanical) lead to the oil filter as the cause of the internal engine noise or damage, dealers should submit a field product report. Refer to Corporate Bulletin Number 02-00-89-002I (Information for Dealers on How to Submit a Field Product Report).

Leak detection dye P/N 12378563 (J 29545-6) (in Canada P/N 88900915) may cause DEX-COOL(R) coolant to appear green in a black vessel making it appear to be conventional (green) coolant. This may cause a technician to add conventional coolant to a low DEX-COOL(R) system thus contaminating it. The green DEX-COOL(R) appearance is caused by the color of the leak detection dye which alters the color of the DEX-COOL(R) coolant. A new leak detection dye P/N 89022219 (J 46366) (in Canada P/N 89022220) has been released that does not alter the appearance of the DEX-COOL(R) coolant. When adding the new leak detection dye the color of the DEX-COOL(R) coolant will not change. For detecting leaks on any system that uses DEX-COOL(R) leak detection dye P/N 89022219 (in Canada P/N 89022220) should be used. The new leak detection dye can be used with both conventional and DEX-COOL(R) coolant.

Coolant Reimbursement Policy General Motors supports the use of recycled engine coolant for warranty repairs/service, providing a GM approved engine coolant recycling system is used. Recycled coolant will be reimbursed at the GMSPO dealer price for new coolant plus the appropriate mark-up. When coolant replacement is required during a warranty repair, it is crucial that only the relative amount of engine coolant concentrate be charged, not the total diluted volume. In other words: if you are using two gallons of pre-diluted (50:50) recycled engine coolant to service a vehicle, you may request reimbursement for one gallon of GM Goodwrench engine coolant concentrate at the dealer price plus the appropriate warranty parts handling allowance. Licensed Approved DEX-COOL(R) Providers Important: USE OF NON-APPROVED VIRGIN OR RECYCLED DEX-COOL(R) OR DEVIATIONS IN THE FORM OF ALTERNATE CHEMICALS OR ALTERATION OF EQUIPMENT, WILL VOID THE GM ENDORSEMENT, MAY DEGRADE COOLANT SYSTEM INTEGRITY AND PLACE THE COOLING SYSTEM WARRANTY UNDER JEOPARDY. Shown in Table 1 are the only current licensed and approved providers of DEX-COOL(R). Products that are advertised as "COMPATIBLE" or "RECOMMENDED" for use with DEX-COOL(R) have not been tested or approved by General Motors. Non-approved coolants may degrade the Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fluids > Coolant > Component Information > Technical Service Bulletins > Cooling System - DEX-COOL(R) Coolant Leak Detection Dye > Page 2840 coolant system integrity and will no longer be considered a 5 yr/150,000 mile (240,000 km) coolant. Coolant Removal Services/Recycling The tables include all coolant recycling processes currently approved by GM. Also included is a primary phone number and demographic information. Used DEX-COOL(R) can be combined with used conventional coolant (green) for recycling. Depending on the recycling service and/or equipment, it is then designated as a conventional 2 yr/30,000 mile (50,000 km) coolant or DEX-COOL(R) 5 yr/150,000 mile (240,000 km) coolant. Recycled coolants as designated in this bulletin may be used during the vehicle(s) warranty period. DEX-COOL(R) Recycling The DEX-COOL(R) recycling service listed in Table 2 has been approved for recycling waste engine coolants (DEX-COOL) or conventional) to DEX-COOL(R) with 5 yr/150,000 mile (240,000 km) usability. Recycling Fluid Technologies is the only licensed provider of Recycled DEX-COOL(R) meeting GM6277M specifications and utilizes GM approved inhibitor packages. This is currently a limited program being monitored by GM Service Operations which will be expanded as demand increases. Conventional (Green) Recycling Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fluids > Coolant > Component Information > Technical Service Bulletins > Cooling System - DEX-COOL(R) Coolant Leak Detection Dye > Page 2841 Processes shown in the Table 3 are capable of recycling waste engine coolants (DEX-COOL(R) or conventional) to a conventional (green) coolant. Recycling conventional coolant can be accomplished at your facility by a technician using approved EQUIPMENT (listed by model number in Table 3), or by an approved coolant recycling SERVICE which may recycle the coolant at your facility or at an offsite operation. Refer to the table for GM approved coolant recyclers in either of these two categories. Should you decide to recycle the coolant yourself, strict adherence to the operating procedures is imperative. Use ONLY the inhibitor chemicals supplied by the respective (GM approved) recycling equipment manufacturer. Sealing Tablets Cooling System Sealing Tablets (Seal Tabs) should not be used as a regular maintenance item after servicing an engine cooling system. Discoloration of coolant can occur if too many seal tabs have been inserted into the cooling system. This can occur if seal tabs are repeatedly used over the service life of a vehicle. Where appropriate, seal tabs may be used if diagnostics fail to repair a small leak in the cooling system. When a condition appears in which seal tabs may be recommended, a specific bulletin will be released describing their proper usage. Water Quality The integrity of the coolant is dependent upon the quality of DEX-COOL(R) and water. DEX-COOL(R) is a product that has enhanced protection capability as well as an extended service interval. These enhanced properties may be jeopardized by combining DEX-COOL(R) with poor quality water. If you suspect the water in your area of being poor quality, it is recommended you use distilled or de-ionized water with DEX-COOL(R). "Pink" DEX-COOL(R) DEX-COOL(R) is orange in color to distinguish it from other coolants. Due to inconsistencies in the mixing of the dyes used with DEX-COOL(R), some batches may appear pink after time. The color shift from orange to pink does not affect the integrity of the coolant, and still maintains the 5 yr/150,000 mile (240,000 km) service interval. Back Service Only use DEX-COOL(R) if the vehicle was originally equipped with DEX-COOL(R). Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fluids > Coolant > Component Information > Technical Service Bulletins > Cooling System - DEX-COOL(R) Coolant Leak Detection Dye > Page 2842 Contamination Mixing conventional green coolant with DEX-COOL(R) will degrade the service interval from 5 yrs./150,000 miles (240,000 km) to 2 yrs./30,000 miles (50,000 km) if left in the contaminated condition. If contamination occurs, the cooling system must be flushed twice immediately and re-filled with a 50/50 mixture of DEX-COOL(R) and clean water in order to preserve the enhanced properties and extended service interval of DEX-COOL(R). After 5 years/150,000 miles (240,000 km) After 5 yrs/150,000 miles (240,000 km), the coolant should be changed, preferably using a coolant exchanger. If the vehicle was originally equipped with DEX-COOL(R) and has not had problems with contamination from non-DEX-COOL(R) coolants, then the service interval remains the same, and the coolant does not need to be changed for another 5 yrs/150,000 miles (240,000 km) Equipment (Coolant Exchangers) The preferred method of performing coolant replacement is to use a coolant exchanger. A coolant exchanger can replace virtually all of the old coolant with new coolant. Coolant exchangers can be used to perform coolant replacement without spillage, and facilitate easy waste collection. They can also be used to lower the coolant level in a vehicle to allow for less messy servicing of cooling system components. It is recommended that you use a coolant exchanger with a vacuum feature facilitates removing trapped air from the cooling system. This is a substantial time savings over repeatedly thermo cycling the vehicle and topping-off the radiator. The vacuum feature also allows venting of a hot system to relieve system pressure. Approved coolant exchangers are available through the GMDE (General Motors Dealer Equipment) program. For refilling a cooling system that has been partially or fully drained for repairs other than coolant replacement, the Vac-N-Fill Coolant Refill Tool (GE-47716) is recommended to facilitate removal of trapped air from the cooling system during refill.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fluids > Coolant > Component Information > Specifications > Capacity Specifications > Page 2845 Coolant: Fluid Type Specifications ENGINE COOLANT The cooling system in your vehicle is filled with DEX-COOL engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL extended life coolant. A 50/50 mixture of clean, drinkable water and DEX-COOL coolant will: - Give freezing protection down to -34°F (-37°C). - Give boiling protection up to 265°F (129°C). - Protect against rust and corrosion. - Help keep the proper engine temperature. - Let the warning lights and gages work as they should. NOTICE: Using coolant other than DEX-COOL may cause premature engine, heater core or radiator corrosion. In addition, the engine coolant may require changing sooner, at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Any repairs would not be covered by your warranty. Always use DEX-COOL (silicate-free) coolant in your vehicle. WHAT TO USE Use a mixture of one-half clean, drinkable water and one-half DEX-COOL coolant which won't damage aluminum parts. If you use this coolant mixture, you don't need to add anything else. CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle's coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you would not get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOL coolant. NOTICE: If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost would not be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts. If you have to add coolant more than four times a year, check your cooling system. NOTICE: If you use the proper coolant, you do not have to add extra inhibitors or additives which claim to improve the system. These can be harmful.

Please discard Corporate Bulletin Number 08-07-30-035A (Section 07 - Transmission/Transaxle). Water or ethylene glycol in automatic transmission fluid (ATF) is harmful to internal transmission components and will have a negative effect on reliability and durability of these parts. Water or ethylene glycol in ATF will also change the friction of the clutches, frequently resulting in shudder during engagement or gear changes, especially during torque converter clutch engagement. Indications of water in the ATF may include: - ATF blowing out of the transmission vent tube. - ATF may appear cloudy or, in cases of extreme contamination, have the appearance of a strawberry milkshake. - Visible water in the oil pan. - A milky white substance inside the pan area. - Spacer plate gaskets that appear to be glued to the valve body face or case. - Spacer plate gaskets that appear to be swollen or wrinkled in areas where they are not compressed. - Rust on internal transmission iron/steel components. If water in the ATF has been found and the source of the water entry has not been identified, or if a leaking in-radiator transmission oil cooler is suspected (with no evidence of cross-contamination in the coolant recovery reservoir), a simple and quick test kit is available that detects the presence of ethylene glycol in ATF. The "Gly-Tek" test kit, available from the Nelco Company, should be obtained and the ATF tested to make an accurate decision on the need for radiator replacement. This can help to prevent customer comebacks if the in-radiator transmission oil cooler is leaking and reduce repair expenses by avoiding radiator replacement if the cooler is not leaking. These test kits can be obtained from: Nelco Company Test kits can be ordered by phone or through the website listed above. Orders are shipped standard delivery time but can be shipped on a next day delivery basis for an extra charge. One test kit will complete 10 individual fluid sample tests. For vehicles repaired under warranty, the cost of the complete test kit plus shipping charges should be divided by 10 and submitted on the warranty claim as a net item. The transmission should be repaired or replaced based on the normal cost comparison procedure. Important If water or coolant is found in the transmission, the following components MUST be replaced. - Replace all of the rubber-type seals. - Replace all of the composition-faced clutch plates and/or bands. - Replace all of the nylon parts. - Replace the torque converter. - Thoroughly clean and rebuild the transmission, using new gaskets and oil filter. Important The following steps must be completed when repairing or replacing. Flush and flow check the transmission oil cooler using J 45096. Refer to Corporate Bulletin Number 02-07-30-052F- Automatic Transmission Oil Cooler Flush and Flow Test Essential Tool J 45096 TransFlow. - Thoroughly inspect the engine cooling system and hoses and clean/repair as necessary.

Only those oils displaying the dexos‹›(TM) trademark and icon on the front label meet the demanding performance requirements and stringent quality standards set forth in the dexos‹›(TM) specification. Look on the front label for any of the logos shown above to identify an authorized, licensed dexos 1(TM) engine oil. GM dexos 1(TM) Engine Oil Specification Important General Motors dexos 1(TM) engine oil specification replaces the previous General Motors specifications GM6094M, GM4718M and GM-LL-A-025 for most GM gasoline engines. The oil specified for use in GM passenger cars and trucks, PRIOR to the 2011 model year remains acceptable for those previous vehicles. However, dexos 1(TM) is backward compatible and can be used in those older vehicles. In North America, starting with the 2011 model year, GM introduced dexos 1(TM) certified engine oil as a factory fill and service fill for gasoline engines. The reasons for the new engine oil specification are as follows: - To meet environmental goals such as increasing fuel efficiency and reducing engine emissions. - To promote long engine life. - To minimize the number of engine oil changes in order to help meet the goal of lessening the industry's overall dependence on crude oil. dexos 1(TM) is a GM-developed engine oil specification that has been designed to provide the following benefits: - Further improve fuel economy, to meet future corporate average fuel economy (CAFE) requirements and fuel economy retention by allowing the oil to maintain its fuel economy benefits throughout the life of the oil. - More robust formulations for added engine protection and aeration performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fluids > Engine Oil > Component Information > Technical Service Bulletins > Engine - GM dexos 1 and dexos 2(R) Oil Specifications > Page 2867 - Support the GM Oil Life System, thereby minimizing the replacement of engine oil, before its life has been depleted. - Reduce the duplication of requirements for a large number of internal GM engine oil specifications. International Lubricants Standardization and Approval Committee (ILSAC) GF-5 Standard In addition to GM dexos 1(TM), a new International Lubricants Standardization and Approval Committee (ILSAC) standard called GF-5, was introduced in October 2010. - There will be a corresponding API category, called: SN Resource Conserving. The current GF-4 standard was put in place in 2004 and will become obsolete in October 2011. Similar to dexos 1(TM), the GF-5 standard will use a new fuel economy test, Sequence VID, which demands a statistically significant increase in fuel economy versus the Sequence VIB test that was used for GF-4. - It is expected that all dexos 1(TM) approved oils will be capable of meeting the GF-5 standard. However, not all GF-5 engine oils will be capable of meeting the dexos 1(TM) specification. - Like dexos(TM), the new ILSAC GF-5 standard will call for more sophisticated additives. The API will begin licensing marketers during October 2010, to produce and distribute GF-5 certified products, which are expected to include SAE 0W-20, 0W-30, 5W-20, 5W-30 and 10W-30 oils. Corporate Average Fuel Economy (CAFE) Requirements Effect on Fuel Economy Since CAFE standards were first introduced in 1974, the fuel economy of cars has more than doubled, while the fuel economy of light trucks has increased by more than 50 percent. Proposed CAFE standards call for a continuation of increased fuel economy in new cars and trucks. To meet these future requirements, all aspects of vehicle operation are being looked at more critically than ever before. New technology being introduced in GM vehicles designed to increase vehicle efficiency and fuel economy include direct injection, cam phasing, turbocharging and active fuel management (AFM). The demands of these new technologies on engine oil also are taken into consideration when determining new oil specifications. AFM for example can help to achieve improved fuel economy. However alternately deactivating and activating the cylinders by not allowing the intake and exhaust valves to open contributes to additional stress on the engine oil. Another industry trend for meeting tough fuel economy mandates has been a shift toward lower viscosity oils. dexos 1(TM) will eventually be offered in several viscosity grades in accordance with engine needs: SAE 0W-20, 5W-20, 0W-30 and 5W-30. Using the right viscosity grade oil is critical for proper engine performance. Always refer to the Maintenance section of a vehicle Owner Manual for the proper viscosity grade for the engine being serviced. GM Oil Life System in Conjunction With dexos (TM) Supports Extended Oil Change Intervals To help conserve oil while maintaining engine protection, many GM vehicles are equipped with the GM Oil Life System. This system can provide oil change intervals that exceed the traditional 3,000 mile (4,830 km) recommendation. The dexos (TM) specification, with its requirements for improved oil robustness, compliments the GM Oil Life System by supporting extended oil change intervals over the lifetime of a vehicle. If all GM customers with GM Oil Life System equipped vehicles would use the system as intended, GM estimates that more than 100 million gallons of oil could be saved annually. GM dexos 2(TM) Information Center Website Refer to the following General Motors website for dexos 2(TM) information about the different licensed brands that are currently available: http://www.gmdexos.com GM dexos 2(TM) Engine Oil Trademark and Icons Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fluids > Engine Oil > Component Information > Technical Service Bulletins > Engine - GM dexos 1 and dexos 2(R) Oil Specifications > Page 2868 The dexos (TM) specification and trademarks are exclusive to General Motors, LLC. Only those oils displaying the dexos (TM) trademark and icon on the front label meet the demanding performance requirements and stringent quality standards set forth in the dexos (TM)specification. Look on the front label for any of the logos shown above to identify an authorized, licensed dexos 2(TM) engine oil. GM dexos 2(TM) Engine Oil Specification - dexos 2(TM) is approved and recommended by GM for use in Europe starting in model year 2010 vehicles, regardless of where the vehicle was manufactured. - dexos 2(TM) is the recommended service fill oil for European gasoline engines. Important The Duramax(TM) diesel engine is the exception and requires lubricants meeting specification CJ-4. - dexos 2(TM) is the recommended service fill oil for European light-duty diesel engines and replaces GM-LL-B-025 and GM-LL-A-025. - dexos 2(TM) protects diesel engines from harmful soot deposits and is designed with limits on certain chemical components to prolong catalyst life and protect expensive emission reduction systems. It is a robust oil, resisting degradation between oil changes and maintaining optimum performance longer.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fluids > Engine Oil > Component Information > Specifications > Capacity Specifications > Page 2872 Engine Oil: Fluid Type Specifications ENGINE OIL TYPE LOOK FOR TWO THINGS: 1.Your vehicle's engine requires oil meeting GM Standard GM6094M. 2.SAE 5W-30 is best for your vehicle. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). You should look for this information on the oil container, and use only those oils that are identified as meeting GM Standard GM6094M and have the starburst symbol on the front of the oil container. NOTICE: Use only engine oil identified as meeting GM Standard GM6094M and showing the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty. GM Goodwrench oil meets all the requirements for your vehicle. If you are in an area of extreme cold, where the temperature falls below -20°F (-29°C), it is recommended that you use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures. ENGINE OIL ADDITIVES Do not add anything to your oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you will need for good performance and engine protection.

The ACR2000 (J-43600) cannot be manufactured in its current state after December 2007 and will be superseded by GE-48800. The new J2788 standard does not require that GM Dealers replace their ACR2000 units. ACR2000's currently in use are very capable of servicing today's refrigerant systems when used correctly and can continue to be used. Details regarding the new SAE J2788 standard are outlined in GM Bulletin 07-01-38-004. Effective February 1 2008, new A/C Refrigerant Recovery/Recharging equipment (P/N GE-48800) will be released as a required replacement for the previously essential ACR2000 (J-43600). This equipment is SAE J2788 compliant and meets GM requirements for A/C Refrigerant System Repairs on all General Motors vehicles, including Hybrid systems with Polyolester (POE) refrigerant oil. This equipment will not be shipped as an essential tool to GM Dealerships. In addition, this equipment is Hybrid compliant and designed to prevent oil cross contamination when servicing Hybrid vehicles with Electric A/C Compressors that use POE refrigerant oil. The ACR2000 (J-43600) will need to be retrofitted with a J-43600-50 (Hose - ACR2000 Oil Flush Loop) to be able to perform Hybrid A/C service work. All Hybrid dealers will receive the J-43600-50, with installation instructions, as a component of the Hybrid essential tool package. Dealerships that do not sell Hybrids, but may need to service Hybrids, can obtain J-43600-50 from SPX Kent Moore. Refer to GM Bulletin 08-01-39-001 for the ACR2000 Hose Flush procedure. The High Voltage (HV) electric A/C compressor used on Two Mode Hybrid vehicles uses a Polyolester (POE) refrigerant oil instead of a Polyalkylene Glycol (PAG) synthetic refrigerant oil. This is due to the better electrical resistance of the POE oil and its ability to provide HV isolation. Failure to flush the hoses before adding refrigerant to a Hybrid vehicle with an electric A/C compressor may result in an unacceptable amount of PAG oil entering the refrigerant system. It may cause a Battery Energy Control Module Hybrid Battery Voltage System Isolation Lost Diagnostic Trouble Code (DTC P1AE7) to be set. Additionally, the A/C system warranty will be voided. Warranty Submission Requirements The Electronically Generated Repair Data (snapshot summary) and printer functions have been eliminated from the GE-48800. The VGA display and temperature probes were eliminated to reduce equipment costs. As a result, effective immediately the 18 digit "Snapshot/Charge Summary" code is no longer required for Air Conditioning (A/C) refrigerant system repairs that are submitted for warranty reimbursement. The charge summary data from before and after system repairs will continue to required, but documented on the repair order only. Both high and low pressures and the recovery and charge amounts should be noted during the repair and entered on the repair order. If using ACR2000 (J-43600), the "Snapshot/Charge Summary" printouts should continue to be attached to the shops copy of the repair order. The labor codes that are affected by this requirement are D3000 through D4500.

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice . Important: Before performing the antilock brake system (ABS) Automated Bleed Procedure, first perform a manual or pressure bleed of the base brake system. The automated bleed procedure is recommended when one of the following conditions exist: * Base brake system bleeding does not achieve the desired pedal height or feel * Extreme loss of brake fluid has occurred * Air ingestion is suspected in the secondary circuits of the brake modulator assembly The ABS Automated Bleed Procedure uses a scan tool to cycle the system solenoid valves and run the pump in order to purge any air from the secondary circuits. These circuits are normally closed off, and are only opened during system initialization at vehicle start up and during ABS operation. The automated bleed procedure opens these secondary circuits and allows any air trapped in these circuits to flow out toward the brake corners. Automated Bleed Procedure Notice: The Auto Bleed Procedure may be terminated at any time during the process by pressing the EXIT button. No further Scan Tool prompts pertaining to the Auto Bleed procedure will be given. After exiting the bleed procedure, relieve bleed pressure and disconnect bleed equipment per manufacturers instructions. Failure to properly relieve pressure may result in spilled brake fluid causing damage to components and painted surfaces. 1. Raise and support the vehicle. 2. Remove all 4 tire and wheel assemblies. 3. Inspect the brake system for leaks and visual damage. Repair or replace components as needed. 4. Lower the vehicle. 5.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Air Bag(s) Arming and Disarming > System Information > Service and Repair Air Bag(s) Arming and Disarming: Service and Repair SIR Disabling and Enabling SIR component location affects how a vehicle should be serviced. There are parts of the SIR system installed in various locations around a vehicle. To find the location of the SIR components refer to SIR Identification Views. There are several reasons for disabling the SIR system, such as repairs to the SIR system or servicing a component near or attached to an SIR component. There are several ways to disable the SIR system depending on what type of service is being performed. The following information covers the proper procedures for disabling/enabling the SIR system. SIR Service Precautions Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Failure to observe the correct procedure could cause deployment of the SIR components. Serious injury can occur. Failure to observe the correct procedure could also result in unnecessary SIR system repairs. The inflatable restraint sensing and diagnostic module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the air bags if the SDM loses battery power during a collision. Deployment power is available for as much as 1 minute after disconnecting the vehicle power. Waiting 1 minute before working on the system after disabling the SIR system prevents deployment of the air bags from the reserved energy supply. General Service Instructions The following are general service instructions which must be followed in order to properly repair the vehicle and return it to its original integrity: * Do not expose inflator modules to temperatures above 65°C (150°F). * Verify the correct replacement part number. Do not substitute a component from a different vehicle. * Use only original GM replacement parts available from your authorized GM dealer. Do not use salvaged parts for repairs to the SIR system. Discard any of the following components if it has been dropped from a height of 91 cm (3 feet) or greater: * Inflatable restraint sensing and diagnostic module (SDM) * Any Inflatable restraint air bag module * Inflatable restraint steering wheel module coil * Any Inflatable restraint sensor * Inflatable restraint seat belt pretensioners * Inflatable restraint Passenger Presence System (PPS) module or sensor Disabling Procedure - Air Bag Fuse 1. Turn the steering wheel so that the vehicles wheels are pointing straight ahead. 2. Place the ignition in the OFF position. Important: The SDM may have more than one fused power input. To ensure there is no unwanted SIR deployment, personal injury, or unnecessary SIR system repairs, remove all fuses supplying power to the SDM. With all SDM fuses removed and the ignition switch in the ON position, the AIR BAG warning indicator illuminates. This is normal operation, and does not indicate a SIR system malfunction. 3. Locate and remove the fuse(s) supplying power to the SDM. 4. Wait 1 minute before working on the system. Enabling Procedure - Air Bag Fuse 1. Place the ignition in the OFF position.

In two cases, these fuses have not provided protection for the wiring system of the vehicles they were customer installed in. Upon testing the 15 amp version, it was found that the fuse still would not "open" when shorted directly across the battery terminals. How to Identify These Fuses Packed in a 120 piece set, the fuse has a translucent, hard plastic, blue body with the amperage stamped into the top. There are no white painted numbers on the fuse to indicate amperage. There are no identifying marks on the fuse to tell who is making it. The fuses are known to be distributed by Harbor Freight Tools but there may be other marketers, and packaging of this style of fuse. It would be prudent to replace these fuses if found in a customers vehicle. Likewise, if wiring overheating is found you should check the fuse panel for the presence of this style of fuse. All GM dealers should use genuine GM fuses on the vehicles they service. You should also encourage the use of GM fuses to your customers to assure they are getting the required electrical system protection. GM has no knowledge of any concerns with other aftermarket fuses. If additional information becomes available, this bulletin will be updated.

Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2931 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2932 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2933 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2934 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2935 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2936 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2937 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2938 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2939 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2940 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2958 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2959 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 3004 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 3005 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 3006 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire.

Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 3011 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 3013 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 3014 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 3015 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 3016 4.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3034 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3035 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3036 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3037 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3038 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3039 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3040 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3041 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3042 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3043 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3061 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3062 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1.

Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3065 3. Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3107 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3108 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3109 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 3118 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

IMPORTANT: Apply the mylar tape with the aluminum side inward. This ensures good electrical contact with the drain wire. Re-assemble the cable. Rewrap the conductors with the mylar tape. - Use caution not to wrap the drain wire in the tape (1). - Follow the splicing instructions for copper wire and splice the drain wire. - Wrap the drain wire around the conductors and tape with mylar tape. 5. Tape over the entire cable. Use a winding motion when you apply the tape.

Maintaining proper tire pressures is an Owner's Maintenance item and is not covered under warranty. This bulletin is being revised to add model years and update additional bulletin reference information. Please discard Corporate Bulletin Number 09-03-16-002 (Section 03 -- Suspension). Customer Concerns and Confusion with the Tire Pressure Monitoring (TPM) System The following procedure should be used by dealership service consultants when a customer comes into the service drive with a "low tire light" on or comments on a check tire pressure/low tire pressure/add air to tire or service tire monitor system message. The service consultant should perform the following steps: Procedure Turn the key to ON, without starting the engine. ^ If the low tire light comes on and stays on solid with a check tire pressure/low tire pressure/add air to tire message (on vehicles equipped with DIC), advise the customer: - The system is working properly. - Properly adjusting all tire air pressures to the recommended levels and driving the vehicle will turn the light off (refer to the Tire and Loading Information label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". ^ If the Tire Pressure Monitor (TPM) light blinks for one minute then stays on solid with a service tire monitor system message (on vehicles equipped with DIC): - A TPM system problem exists. The vehicle should be written up accordingly and sent to your service department for further DTC diagnosis and service. - If dashes (--) are displayed in only one or two of the tire pressure readouts, it is likely caused by a previous TPM system relearn that was performed incorrectly due to interference from another vehicle's TPM system during the relearn process (refer to the Important statement later in this bulletin regarding TPM relearn with a Tech 2(R)). - If dashes (--) are displayed in all four of the tire pressure readouts, there is a system problem. Follow the appropriate SI service procedures. ^ If a customer indicates the low tire light comes on for a few minutes when the vehicle is started, then goes off after driving a while, advise the customer: - The system is working properly. - Most likely, air pressure in one or more of the tires is low enough to turn the light on when tires are cold. After driving for a while, tires will heat Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Service Reminder Indicators > Low Tire Pressure Indicator > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 3161 up, allowing tire air pressure to increase above the threshold causing the light to go off. Properly adjusting all tire air pressures to the recommended levels will correct this (Refer to the Tire and Loading Information Label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". For more detailed information, refer to Corporate Bulletin Number 07-03-16-004C and TPMS Training Course 13044.12T2. Tire Pressure Light At key on, without starting the vehicle: Steady Solid Glowing TPM Indicator If the TPM indicator appears as a steady glowing yellow lamp (as above), the system is functioning properly and you should add air to the tires to correct this condition. Blinking TPM Indicator If the TPM indicator appears as a BLINKING yellow lamp for one minute and then stays on solid, diagnostic service is needed. The Effect of Outside Temperature on Tire Pressures Important: As a rule of thumb, tire pressure will change about 7kPa (1 psi) for every 6°C (10°F) decrease in temperature - Tire pressure will drop when it gets colder outside, and rise when it gets warmer. Under certain situations such as extreme outside temperature changes, the system may bring on a solid light with a check tire pressure message. This should be considered normal and the system is working properly. The light will turn off upon adding the proper amount of air to the tires (refer to the Tire & Loading Information label in the driver's door opening). When properly adjusting tire air pressure, the following steps are important to help optimize the system and prolong bringing a tire pressure light on: ^ Use an accurate, high quality tire pressure gauge. ^ Never set the tire pressure below the specified placard value regardless of tire temperature or ambient temperature. ^ Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will encounter during operation. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Service Reminder Indicators > Low Tire Pressure Indicator > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 3162 ^ When adding proper tire air pressure, it is important to remember fluctuations in outside air temperatures and tire temperatures effect tire air pressures. ^ After you have added the proper tire pressure, if the vehicle has a DIC (after the system has updated), check to see if DIC displays are the same readings as the tire pressure gauge used (adjust as necessary). ^ Only perform a TPM sensor re-learn after a tire rotation or system part replacements and use the Tech 2(R) to initiate the relearn whenever possible to avoid invalid sensor I.D. learns. Important: Always take outside temperature and tire temperature into consideration to properly set tire pressures. Foe example, on colder days (20°F/-7°C), if setting tire pressure when the vehicle has been indoors (60°F/16°C) or the tires are warm from being driven, it will be necessary to compensate for the low outside temperature by adding 21-27 kPa (3-4 psi) more then the placecard pressure. At some later time, when the vehicle has been parked outside for a while, the tires will cool off and the pressures will drop back into the placecard range. Important: Recently, nitrogen gas (for use in inflating tires) has become available to the general customer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. Tires inflated with nitrogen gas may exhibit less of a pressure change in response to outside temperature changes. Nitrogen gas inflation is compatible with GM TPM sensors. For additional information, refer to Corporate Service Bulletin 05-03-10-020C. Important: All Models (Except the Pontiac Vibe): Do not perform a TPM relearn at PDI, the system has already been set at the Assembly Plant. Do not perform a TPM relearn after adding air to the tires. The low tire light is similar to the low fuel indicator and adding something (fuel, air) to the vehicle makes that light turn back off again. Note that because of system behavior, some vehicles must be driven a short distance before the sensors recognize the increase in pressure and turns the light off again. Pontiac Vibe Only: Do not use the TPMS reset button to turn off the light. The system will update and light will turn off when all tire pressures have been adjusted followed by short distance drive. Important: All models (except the Pontiac Vibe): Each tire monitor sensor is learned to a specific vehicle corner. When performing a TPM relearn (only after a tire rotation or replacement of a TPM sensor or Module), always use the Tech2(R) to initiate the J 46079 relearned process. Tech 2(R) - initiated relearns lock out other vehicle TPM signals that may be broadcasting in the area. Only signals initiated by the J 46079 tool will be accepted. This method avoids storing false TPM I.D.s and will prevent customers from returning with dashes (--) displayed in tire pressure readouts and/or a flashing tire pressure monitor (TPM) light. Checking the four TPM I.D.s with the Tech 2(R) prior to and following relearn to verify they are the same can prevent invalid I.D. learns. Pontiac Vibe Only: Tire Monitor Sensors are not learned to a specific vehicle corner. Do not perform a TPM Reset after tire rotation. The TPMS Reset button must only be used during pre-delivery inspection by the dealer to initialize the system (after all tire pressures have been adjusted properly) or when a Tire Pressure Monitor System component is replaced. The J 46079 tool does not work on Vibe TPM sensors. A TPMS relearn on Vibe must be preformed with a Tech 2(R) to set the TPMS Module in learn mode. The TPMS sensor IDs are entered through the Tech 2(R). Refer to SI for further Vibe TPMS information. Labor Operation and Repair Order/Warranty System Claim Required Documentation Important: The ONLY time labor operation E0726 or E0722 should be used is to diagnose for a system issue. That should ONLY occur if, at key ON, without starting the engine, the Tire Pressure Monitor (TPM) blinks for one minute and then stays on solid with a Service Tire Monitor System message (on vehicles equipped with a DIC) If that occurs, a TPM system problem exists and the system will have set a DTC. If one of these operastions is used, the following Repair Order and Warranty System documentation are required: ^ Document the customer complaint on the Repair Order. ^ Document the TPMS DTC that has set on the Repair Order. ^ Enter the TPMS DTC in the Warranty System (WINS) in the Failure Code/DTC field on the claim submission (refer to the Claims Processing Manual, Section IV, Warranty claim Data, Page 6, Item G). If the above information is not documented on the Repair Order and Warranty System, the claim may be rejected. If the Warranty Parts Center (WPC) generates a request, this repair order documentation must be sent back.

This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A "CHANGE ENGINE OIL SOON" message will come on. Change your oil as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. It is also important to check your oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed. HOW TO RESET THE ENGINE OIL LIFE SYSTEM The Engine Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a change engine oil light being turned on, reset the system. 1. Turn the ignition key to "RUN" with the engine off. 2. Fully press and release the accelerator pedal three times within five seconds. The "CHANGE ENGINE OIL SOON" message will flash while the system is resetting. 3. When the light stops flashing, turn the key to "LOCK". If the change engine oil light comes back on and stays on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure. WHAT TO DO WITH USED OIL Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.

When dismounting and mounting tires, care must be taken when breaking the bead loose from the wheel. If the tire machines bead breaking fixture is positioned too close to the tire pressure sensor, as the tire bead breaks away from the wheel it may be forced into, or catch on the edge of the tire pressure sensor. This can damage the sensor and require the sensor to be replaced. Care must also be taken when transferring the tire bead to the other side of the wheel rim. As the tire machine rotates and the tire bead is stretched around the wheel rim, the bead can come in contact with the sensor if it is not correctly positioned in relation to the mounting/dismounting head prior to tire mounting/dismounting. This can also cause sensor damage requiring replacement. Procedure Notice: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result. Notice: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel. 1. Remove the valve core from the valve stem. 2. Deflate the tire completely. Important: Rim-clamp European-type tire changers are recommended. 3. Use the tire changer in order to remove the tire from the wheel. Follow steps 4-7 to remove the tire from the wheel. 4. When separating the tire bead from the wheel position the bead breaking fixture 90, 180 and 270 degrees from the valve stem.

Position the wheel and tire so the valve stem is situated at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the outer tire bead up and over the mounting/dismounting head. 6. Position the wheel and tire so that the valve stem is situated again at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the inner tire bead up and over the mounting/dismounting head. 7. Remove all residual liquid sealant from the inside of the tire and wheel surfaces. If any tire sealant is noted upon tire dismounting on vehicles equipped with TPM replace the tire pressure sensor. 8. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats. Important: If bead seat corrosion has been identified as an air loss concern on the wheel being worked on, refer to GM Service Bulletin # 08-03-10-006 for additional information on correcting the leak. 9. Apply GM P/N 12345884 (in Canada, P/N 5728223) or equivalent to the tire bead and the wheel rim.

Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim. 11. Position the rim so that the valve stem (1) is situated at the 3 o'clock position relative to the head (2). This will protect the sensor when the bottom bead seats. 12. After the bottom bead is on the wheel, reposition the wheel and tire so that the valve stem is situated at the 9 o'clock position relative to the head. This will protect the sensor while mounting the tire bead to the outside of the wheel.

Use the tire changer in order to install the tire to the wheel. Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, lubricate the beads and reinflate. Overinflating may cause the bead to break and cause serious personal injury. Important: Allowable bead seating pressure is 345 kPa (50 psi) on Extended Mobility Tires. 14. Inflate the tire until it passes the bead humps. Be sure that the valve core is not installed at this time. 15. Install the valve core to the valve core stem. 16. Inflate the tire to the proper air pressure. 17. Ensure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.

Maintaining proper tire pressures is an Owner's Maintenance item and is not covered under warranty. This bulletin is being revised to add model years and update additional bulletin reference information. Please discard Corporate Bulletin Number 09-03-16-002 (Section 03 -- Suspension). Customer Concerns and Confusion with the Tire Pressure Monitoring (TPM) System The following procedure should be used by dealership service consultants when a customer comes into the service drive with a "low tire light" on or comments on a check tire pressure/low tire pressure/add air to tire or service tire monitor system message. The service consultant should perform the following steps: Procedure Turn the key to ON, without starting the engine. ^ If the low tire light comes on and stays on solid with a check tire pressure/low tire pressure/add air to tire message (on vehicles equipped with DIC), advise the customer: - The system is working properly. - Properly adjusting all tire air pressures to the recommended levels and driving the vehicle will turn the light off (refer to the Tire and Loading Information label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". ^ If the Tire Pressure Monitor (TPM) light blinks for one minute then stays on solid with a service tire monitor system message (on vehicles equipped with DIC): - A TPM system problem exists. The vehicle should be written up accordingly and sent to your service department for further DTC diagnosis and service. - If dashes (--) are displayed in only one or two of the tire pressure readouts, it is likely caused by a previous TPM system relearn that was performed incorrectly due to interference from another vehicle's TPM system during the relearn process (refer to the Important statement later in this bulletin regarding TPM relearn with a Tech 2(R)). - If dashes (--) are displayed in all four of the tire pressure readouts, there is a system problem. Follow the appropriate SI service procedures. ^ If a customer indicates the low tire light comes on for a few minutes when the vehicle is started, then goes off after driving a while, advise the customer: - The system is working properly. - Most likely, air pressure in one or more of the tires is low enough to turn the light on when tires are cold. After driving for a while, tires will heat Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tire Monitoring System > Low Tire Pressure Indicator > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 3204 up, allowing tire air pressure to increase above the threshold causing the light to go off. Properly adjusting all tire air pressures to the recommended levels will correct this (Refer to the Tire and Loading Information Label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". For more detailed information, refer to Corporate Bulletin Number 07-03-16-004C and TPMS Training Course 13044.12T2. Tire Pressure Light At key on, without starting the vehicle: Steady Solid Glowing TPM Indicator If the TPM indicator appears as a steady glowing yellow lamp (as above), the system is functioning properly and you should add air to the tires to correct this condition. Blinking TPM Indicator If the TPM indicator appears as a BLINKING yellow lamp for one minute and then stays on solid, diagnostic service is needed. The Effect of Outside Temperature on Tire Pressures Important: As a rule of thumb, tire pressure will change about 7kPa (1 psi) for every 6°C (10°F) decrease in temperature - Tire pressure will drop when it gets colder outside, and rise when it gets warmer. Under certain situations such as extreme outside temperature changes, the system may bring on a solid light with a check tire pressure message. This should be considered normal and the system is working properly. The light will turn off upon adding the proper amount of air to the tires (refer to the Tire & Loading Information label in the driver's door opening). When properly adjusting tire air pressure, the following steps are important to help optimize the system and prolong bringing a tire pressure light on: ^ Use an accurate, high quality tire pressure gauge. ^ Never set the tire pressure below the specified placard value regardless of tire temperature or ambient temperature. ^ Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will encounter during operation. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tire Monitoring System > Low Tire Pressure Indicator > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 3205 ^ When adding proper tire air pressure, it is important to remember fluctuations in outside air temperatures and tire temperatures effect tire air pressures. ^ After you have added the proper tire pressure, if the vehicle has a DIC (after the system has updated), check to see if DIC displays are the same readings as the tire pressure gauge used (adjust as necessary). ^ Only perform a TPM sensor re-learn after a tire rotation or system part replacements and use the Tech 2(R) to initiate the relearn whenever possible to avoid invalid sensor I.D. learns. Important: Always take outside temperature and tire temperature into consideration to properly set tire pressures. Foe example, on colder days (20°F/-7°C), if setting tire pressure when the vehicle has been indoors (60°F/16°C) or the tires are warm from being driven, it will be necessary to compensate for the low outside temperature by adding 21-27 kPa (3-4 psi) more then the placecard pressure. At some later time, when the vehicle has been parked outside for a while, the tires will cool off and the pressures will drop back into the placecard range. Important: Recently, nitrogen gas (for use in inflating tires) has become available to the general customer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. Tires inflated with nitrogen gas may exhibit less of a pressure change in response to outside temperature changes. Nitrogen gas inflation is compatible with GM TPM sensors. For additional information, refer to Corporate Service Bulletin 05-03-10-020C. Important: All Models (Except the Pontiac Vibe): Do not perform a TPM relearn at PDI, the system has already been set at the Assembly Plant. Do not perform a TPM relearn after adding air to the tires. The low tire light is similar to the low fuel indicator and adding something (fuel, air) to the vehicle makes that light turn back off again. Note that because of system behavior, some vehicles must be driven a short distance before the sensors recognize the increase in pressure and turns the light off again. Pontiac Vibe Only: Do not use the TPMS reset button to turn off the light. The system will update and light will turn off when all tire pressures have been adjusted followed by short distance drive. Important: All models (except the Pontiac Vibe): Each tire monitor sensor is learned to a specific vehicle corner. When performing a TPM relearn (only after a tire rotation or replacement of a TPM sensor or Module), always use the Tech2(R) to initiate the J 46079 relearned process. Tech 2(R) - initiated relearns lock out other vehicle TPM signals that may be broadcasting in the area. Only signals initiated by the J 46079 tool will be accepted. This method avoids storing false TPM I.D.s and will prevent customers from returning with dashes (--) displayed in tire pressure readouts and/or a flashing tire pressure monitor (TPM) light. Checking the four TPM I.D.s with the Tech 2(R) prior to and following relearn to verify they are the same can prevent invalid I.D. learns. Pontiac Vibe Only: Tire Monitor Sensors are not learned to a specific vehicle corner. Do not perform a TPM Reset after tire rotation. The TPMS Reset button must only be used during pre-delivery inspection by the dealer to initialize the system (after all tire pressures have been adjusted properly) or when a Tire Pressure Monitor System component is replaced. The J 46079 tool does not work on Vibe TPM sensors. A TPMS relearn on Vibe must be preformed with a Tech 2(R) to set the TPMS Module in learn mode. The TPMS sensor IDs are entered through the Tech 2(R). Refer to SI for further Vibe TPMS information. Labor Operation and Repair Order/Warranty System Claim Required Documentation Important: The ONLY time labor operation E0726 or E0722 should be used is to diagnose for a system issue. That should ONLY occur if, at key ON, without starting the engine, the Tire Pressure Monitor (TPM) blinks for one minute and then stays on solid with a Service Tire Monitor System message (on vehicles equipped with a DIC) If that occurs, a TPM system problem exists and the system will have set a DTC. If one of these operastions is used, the following Repair Order and Warranty System documentation are required: ^ Document the customer complaint on the Repair Order. ^ Document the TPMS DTC that has set on the Repair Order. ^ Enter the TPMS DTC in the Warranty System (WINS) in the Failure Code/DTC field on the claim submission (refer to the Claims Processing Manual, Section IV, Warranty claim Data, Page 6, Item G). If the above information is not documented on the Repair Order and Warranty System, the claim may be rejected. If the Warranty Parts Center (WPC) generates a request, this repair order documentation must be sent back.

Return rates ran as high as 60% with the TPM sensors still attached. Operational TPM sensors should not be returned to GM and are to be transferred to replacement wheels if they become necessary. Important: Operational TPM Sensors that are returned under warranty to General Motors will be charged back to the dealer.Sensors have a 10 year /150,000 mile (240,000 km) battery life, and should be transferred if one or more wheels are replaced. TPM Valve Stem / Grommet (0-ring) Replacement When the TPM sensors are transferred to new wheels you should replace the component used to seal the TPM sensor stem to the wheel. On sensors with an aluminum stem and visible nut on the outside of the wheel a replacement grommet (0-ring) should be used to assure a proper seal. The sensor retaining nut (except Aveo) should be tightened to 7 N.m (62 lb in) for all vehicles except Pontiac Vibe (4.0 N.m (35.4 lb in)). Important: ^ DO NOT overtorque the retaining nut. Notice: ^ Factory installed TPM Sensors come with plastic aluminum or nickel-plated brass stem caps. These caps should not be changed. Chrome plated steel caps may cause corrosion of aluminum valve stems due to incompatibility of the metals. On current style sensors the entire rubber stem is replaceable. The service interval on the revised TPM sensor with replaceable stem is the same as for any other traditional valve stem. Replace the stem at the time of tire replacement sensor transfer or whenever air seepage is suspected at the valve stem. When replacing the valve stem tighten the screw to 1.3 N.m (11.5 lb in).

When dismounting and mounting tires, care must be taken when breaking the bead loose from the wheel. If the tire machines bead breaking fixture is positioned too close to the tire pressure sensor, as the tire bead breaks away from the wheel it may be forced into, or catch on the edge of the tire pressure sensor. This can damage the sensor and require the sensor to be replaced. Care must also be taken when transferring the tire bead to the other side of the wheel rim. As the tire machine rotates and the tire bead is stretched around the wheel rim, the bead can come in contact with the sensor if it is not correctly positioned in relation to the mounting/dismounting head prior to tire mounting/dismounting. This can also cause sensor damage requiring replacement. Procedure Notice: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result. Notice: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel. 1. Remove the valve core from the valve stem. 2. Deflate the tire completely. Important: Rim-clamp European-type tire changers are recommended. 3. Use the tire changer in order to remove the tire from the wheel. Follow steps 4-7 to remove the tire from the wheel. 4. When separating the tire bead from the wheel position the bead breaking fixture 90, 180 and 270 degrees from the valve stem.

Position the wheel and tire so the valve stem is situated at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the outer tire bead up and over the mounting/dismounting head. 6. Position the wheel and tire so that the valve stem is situated again at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the inner tire bead up and over the mounting/dismounting head. 7. Remove all residual liquid sealant from the inside of the tire and wheel surfaces. If any tire sealant is noted upon tire dismounting on vehicles equipped with TPM replace the tire pressure sensor. 8. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats. Important: If bead seat corrosion has been identified as an air loss concern on the wheel being worked on, refer to GM Service Bulletin # 08-03-10-006 for additional information on correcting the leak. 9. Apply GM P/N 12345884 (in Canada, P/N 5728223) or equivalent to the tire bead and the wheel rim.

Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim. 11. Position the rim so that the valve stem (1) is situated at the 3 o'clock position relative to the head (2). This will protect the sensor when the bottom bead seats. 12. After the bottom bead is on the wheel, reposition the wheel and tire so that the valve stem is situated at the 9 o'clock position relative to the head. This will protect the sensor while mounting the tire bead to the outside of the wheel.

Use the tire changer in order to install the tire to the wheel. Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, lubricate the beads and reinflate. Overinflating may cause the bead to break and cause serious personal injury. Important: Allowable bead seating pressure is 345 kPa (50 psi) on Extended Mobility Tires. 14. Inflate the tire until it passes the bead humps. Be sure that the valve core is not installed at this time. 15. Install the valve core to the valve core stem. 16. Inflate the tire to the proper air pressure. 17. Ensure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.

Maintaining proper tire pressures is an Owner's Maintenance item and is not covered under warranty. This bulletin is being revised to add model years and update additional bulletin reference information. Please discard Corporate Bulletin Number 09-03-16-002 (Section 03 -- Suspension). Customer Concerns and Confusion with the Tire Pressure Monitoring (TPM) System The following procedure should be used by dealership service consultants when a customer comes into the service drive with a "low tire light" on or comments on a check tire pressure/low tire pressure/add air to tire or service tire monitor system message. The service consultant should perform the following steps: Procedure Turn the key to ON, without starting the engine. ^ If the low tire light comes on and stays on solid with a check tire pressure/low tire pressure/add air to tire message (on vehicles equipped with DIC), advise the customer: - The system is working properly. - Properly adjusting all tire air pressures to the recommended levels and driving the vehicle will turn the light off (refer to the Tire and Loading Information label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". ^ If the Tire Pressure Monitor (TPM) light blinks for one minute then stays on solid with a service tire monitor system message (on vehicles equipped with DIC): - A TPM system problem exists. The vehicle should be written up accordingly and sent to your service department for further DTC diagnosis and service. - If dashes (--) are displayed in only one or two of the tire pressure readouts, it is likely caused by a previous TPM system relearn that was performed incorrectly due to interference from another vehicle's TPM system during the relearn process (refer to the Important statement later in this bulletin regarding TPM relearn with a Tech 2(R)). - If dashes (--) are displayed in all four of the tire pressure readouts, there is a system problem. Follow the appropriate SI service procedures. ^ If a customer indicates the low tire light comes on for a few minutes when the vehicle is started, then goes off after driving a while, advise the customer: - The system is working properly. - Most likely, air pressure in one or more of the tires is low enough to turn the light on when tires are cold. After driving for a while, tires will heat Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 3230 up, allowing tire air pressure to increase above the threshold causing the light to go off. Properly adjusting all tire air pressures to the recommended levels will correct this (Refer to the Tire and Loading Information Label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". For more detailed information, refer to Corporate Bulletin Number 07-03-16-004C and TPMS Training Course 13044.12T2. Tire Pressure Light At key on, without starting the vehicle: Steady Solid Glowing TPM Indicator If the TPM indicator appears as a steady glowing yellow lamp (as above), the system is functioning properly and you should add air to the tires to correct this condition. Blinking TPM Indicator If the TPM indicator appears as a BLINKING yellow lamp for one minute and then stays on solid, diagnostic service is needed. The Effect of Outside Temperature on Tire Pressures Important: As a rule of thumb, tire pressure will change about 7kPa (1 psi) for every 6°C (10°F) decrease in temperature - Tire pressure will drop when it gets colder outside, and rise when it gets warmer. Under certain situations such as extreme outside temperature changes, the system may bring on a solid light with a check tire pressure message. This should be considered normal and the system is working properly. The light will turn off upon adding the proper amount of air to the tires (refer to the Tire & Loading Information label in the driver's door opening). When properly adjusting tire air pressure, the following steps are important to help optimize the system and prolong bringing a tire pressure light on: ^ Use an accurate, high quality tire pressure gauge. ^ Never set the tire pressure below the specified placard value regardless of tire temperature or ambient temperature. ^ Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will encounter during operation. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 3231 ^ When adding proper tire air pressure, it is important to remember fluctuations in outside air temperatures and tire temperatures effect tire air pressures. ^ After you have added the proper tire pressure, if the vehicle has a DIC (after the system has updated), check to see if DIC displays are the same readings as the tire pressure gauge used (adjust as necessary). ^ Only perform a TPM sensor re-learn after a tire rotation or system part replacements and use the Tech 2(R) to initiate the relearn whenever possible to avoid invalid sensor I.D. learns. Important: Always take outside temperature and tire temperature into consideration to properly set tire pressures. Foe example, on colder days (20°F/-7°C), if setting tire pressure when the vehicle has been indoors (60°F/16°C) or the tires are warm from being driven, it will be necessary to compensate for the low outside temperature by adding 21-27 kPa (3-4 psi) more then the placecard pressure. At some later time, when the vehicle has been parked outside for a while, the tires will cool off and the pressures will drop back into the placecard range. Important: Recently, nitrogen gas (for use in inflating tires) has become available to the general customer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. Tires inflated with nitrogen gas may exhibit less of a pressure change in response to outside temperature changes. Nitrogen gas inflation is compatible with GM TPM sensors. For additional information, refer to Corporate Service Bulletin 05-03-10-020C. Important: All Models (Except the Pontiac Vibe): Do not perform a TPM relearn at PDI, the system has already been set at the Assembly Plant. Do not perform a TPM relearn after adding air to the tires. The low tire light is similar to the low fuel indicator and adding something (fuel, air) to the vehicle makes that light turn back off again. Note that because of system behavior, some vehicles must be driven a short distance before the sensors recognize the increase in pressure and turns the light off again. Pontiac Vibe Only: Do not use the TPMS reset button to turn off the light. The system will update and light will turn off when all tire pressures have been adjusted followed by short distance drive. Important: All models (except the Pontiac Vibe): Each tire monitor sensor is learned to a specific vehicle corner. When performing a TPM relearn (only after a tire rotation or replacement of a TPM sensor or Module), always use the Tech2(R) to initiate the J 46079 relearned process. Tech 2(R) - initiated relearns lock out other vehicle TPM signals that may be broadcasting in the area. Only signals initiated by the J 46079 tool will be accepted. This method avoids storing false TPM I.D.s and will prevent customers from returning with dashes (--) displayed in tire pressure readouts and/or a flashing tire pressure monitor (TPM) light. Checking the four TPM I.D.s with the Tech 2(R) prior to and following relearn to verify they are the same can prevent invalid I.D. learns. Pontiac Vibe Only: Tire Monitor Sensors are not learned to a specific vehicle corner. Do not perform a TPM Reset after tire rotation. The TPMS Reset button must only be used during pre-delivery inspection by the dealer to initialize the system (after all tire pressures have been adjusted properly) or when a Tire Pressure Monitor System component is replaced. The J 46079 tool does not work on Vibe TPM sensors. A TPMS relearn on Vibe must be preformed with a Tech 2(R) to set the TPMS Module in learn mode. The TPMS sensor IDs are entered through the Tech 2(R). Refer to SI for further Vibe TPMS information. Labor Operation and Repair Order/Warranty System Claim Required Documentation Important: The ONLY time labor operation E0726 or E0722 should be used is to diagnose for a system issue. That should ONLY occur if, at key ON, without starting the engine, the Tire Pressure Monitor (TPM) blinks for one minute and then stays on solid with a Service Tire Monitor System message (on vehicles equipped with a DIC) If that occurs, a TPM system problem exists and the system will have set a DTC. If one of these operastions is used, the following Repair Order and Warranty System documentation are required: ^ Document the customer complaint on the Repair Order. ^ Document the TPMS DTC that has set on the Repair Order. ^ Enter the TPMS DTC in the Warranty System (WINS) in the Failure Code/DTC field on the claim submission (refer to the Claims Processing Manual, Section IV, Warranty claim Data, Page 6, Item G). If the above information is not documented on the Repair Order and Warranty System, the claim may be rejected. If the Warranty Parts Center (WPC) generates a request, this repair order documentation must be sent back.

Please discard Corporate Bulletin Number 04-03-10-001E (Section 03 - Suspension). This bulletin covers puncture repair procedures for passenger car and light duty truck radial tires in the tread area only. The tire manufacturer must be contacted for its individual repair policy and whether or not the speed rating is retained after repair. Caution - Tire changing can be dangerous and should be done by trained professionals using proper tools and procedures. Always read and understand any manufacturer's warnings contained in their customers literature or molded into the tire sidewall. - Serious eye and ear injury may result from not wearing adequate eye and ear protection while repairing tires. - NEVER inflate beyond 275 kPa (40 pounds) pressure to seat beads. Some run flat tires, such as the Goodyear Extended Mobility Tire (EMT) used on the Corvette, may require more than 275 kPa (40 psi) to seat the bead. In such a case, a tire safety cage must be used. Consult the tire manufacturer for its individual repair policy. - NEVER stand, lean or reach over the assembly during inflation. Repairable area on a radial tire. Important - NEVER repair tires worn to the tread indicators 1.59 mm (2/32") remaining depth). - NEVER repair tires with a tread puncture larger than 6.35 mm (1/4"). - NEVER substitute an inner tube for a permissible or non-permissible repair. - NEVER perform an outside-in tire repair (plug only, on the wheel). - Every tire must be removed from the wheel for proper inspection and repair. - Regardless of the type of repair used, the repair must seal the inner liner and fill the injury. - Consult with repair material supplier/manufacturer for repair unit application procedures and repair tools/repair material recommendations. Three basic steps for tire puncture repair: 1. Remove the tire from the wheel for inspection and repair. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 04-03-10-001F > Apr > 10 > Tires/Wheels - Tire Puncture Repair Procedures > Page 3244 2. Fill the injury (puncture) to keep moisture out. 3. Seal the inner liner with a repair unit to prevent air loss. External Inspection 1. Prior to demounting, inspect the tire surface, the valve and the wheel for the source of the leak by using a water and soap solution. Mark the injured area and totally deflate the tire by removing the valve core. 2. Demount the tire from the wheel and place the tire on a well-lighted spreader. Internal Inspection 1. Spread the beads and mark the puncture with a tire crayon. 2. Inspect the inner tire for any signs of internal damage. 3. Remove the puncturing object, noting the direction of the penetration. 4. Probe the injury with a blunt awl in order to determine the extent and direction of the injury. 5. Remove any loose foreign material from the injury. 6. Punctures exceeding 6.35 mm (1/4") should not be repaired. Cleaning 1. Clean the area around the puncture thoroughly with a proper liner cleaner, clean cloth and a scraper. This step serves to remove dirt and mold lubricants to insure proper adhesion and non-contamination of the buffing tool. 2. Refer to information on the product or manufacturer's Material Safety Data Sheet and follow guidelines for handling and disposal. Clean the Injury Channel Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 04-03-10-001F > Apr > 10 > Tires/Wheels - Tire Puncture Repair Procedures > Page 3245 1. Use a proper hand reamer, carbide cutter or drill bit to ream the puncture channel from the inside of the tire in order to clean the injury. 2. Remove steel wires protruding above the liner surface to prevent damage to the repair unit. 3. Consult your repair material supplier for recommended reaming tool(s). Fill the Injury 1. It is necessary to fill the injury channel to provide back up for the repair unit and to prevent moisture from entering the tire fabric and steel wires. 2. (For combination repair/plug units skip this step.) Cement the injured channel and fill the injury from the inside of the tire with the repair plug per repair material manufacturer's recommendations. Without stretching the plug, cut the plug off just above the inside tire surface. 3. Consult your repair material supplier for proper repair material selection. Repair Unit Selection Important Do not install the repair unit in this step. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 04-03-10-001F > Apr > 10 > Tires/Wheels - Tire Puncture Repair Procedures > Page 3246 1. Center the repair unit over the injury as a reference and outline an area larger than the unit so that buffing will not remove the crayon marks. 2. Remove the repair unit. 3. DO NOT overlap previous or multiple repair units. 4. Consult your repair material supplier for proper repair unit selection. Buffing 1. To prevent contamination and preserve the outline, buff within the marked area thoroughly and evenly with a low speed buffing tool using a fine wire brush or gritted rasp. 2. Buff to a smooth velvet surface (RMA #1 or #2 buffed texture). 3. Use caution not to gouge the inner liner or expose casing fabric. 4. Remove any buffing dust with a vacuum cleaner. 5. Consult your repair material supplier for a proper buffing tool. Cementing Apply chemical cement according to the repair material manufacturer's procedures.

The tire must be in the relaxed position when the repair unit is installed (Do not spread the beads excessively). Two-Piece Plug and Repair Units 1. If applicable, install the repair unit so that the alignment is correct. 2. Center the repair unit over the injury and stitch down thoroughly with the stitching tool, working from the center out. 3. Being careful not to stretch the plug material, cut the plug flush with the outer tread. Combination Repair/Plug Units 1. Pull the plug through the injury until the repair just reaches the liner. Stitch down thoroughly. 2. Follow the repair material manufacturer's recommendations for further installation instructions. 2. Consult your repair material supplier for the proper stitching tool. Safety Cage Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 04-03-10-001F > Apr > 10 > Tires/Wheels - Tire Puncture Repair Procedures > Page 3248 Some run flat tires, such as the Goodyear Extended Mobility Tire (EMT) used on the Corvette, may require more than 275 kPa (40 psi) to seat the bead. In such a case, a tire safety cage must be used. Consult the tire manufacturer for its individual repair policy. Final Inspection 1. After remounting and inflating the tire, check both beads, the repair and the valve with a water and soap solution in order to detect leaks. 2. If the tire continues to lose air, the tire must be demounted and reinspected. 3. Balance the tire and wheel assembly. Refer to Tire and Wheel Assembly Balancing - OFF Vehicle.

GM's Position on the Use of Nitrogen Gas in Tires General Motors does not oppose the use of purified nitrogen as an inflation gas for tires. We expect the theoretical benefits to be reduced in practical use due to the lack of an existing infrastructure to continuously facilitate inflating tires with nearly pure nitrogen. Even occasional inflation with compressed atmospheric air will negate many of the theoretical benefits. Given those theoretical benefits, practical limitations, and the robust design of GM original equipment TPC tires, the realized benefits to our customer of inflating their tires with purified nitrogen are expected to be minimal. The Promise of Nitrogen: Under Controlled Conditions Recently, nitrogen gas (for use in inflating tires) has become available to the general consumer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. The following benefits under controlled conditions are attributed to nitrogen gas and its unique properties: - A reduction in the expected loss of Tire Pressure over time. - A reduction in the variance of Tire Pressures with temperature changes due to reduction of water vapor concentration. - A reduction of long term rubber degradation due to a decrease in oxygen concentrations. Important These are obtainable performance improvements when relatively pure nitrogen gas is used to inflate tires under controlled conditions. The Promise of Nitrogen: Real World Use Nitrogen inflation can provide some benefit by reducing gas migration (pressure loss) at the molecular level through the tire structure. NHTSA (National Highway Traffic Safety Administration) has stated that the inflation pressure loss of tires can be up to 5% a month. Nitrogen molecules are larger than oxygen molecules and, therefore, are less prone to "seeping" through the tire casing. The actual obtainable benefits of nitrogen vary, based on the physical construction and the materials used in the manufacturing of the tire being inflated. Another potential benefit of nitrogen is the reduced oxidation of tire components. Research has demonstrated that oxygen consumed in the oxidation process of the tire primarily comes from the inflation media. Therefore, it is reasonable to assume that oxidation of tire components can be reduced if the tire is inflated with pure nitrogen. However, only very small amounts of oxygen are required to begin the normal oxidation process. Even slight contamination of the tire inflation gas with compressed atmospheric air during normal inflation pressure maintenance, may negate the benefits of using nitrogen. GM Tire Quality, Technology and Focus of Importance Since 1972, General Motors has designed tires under the TPC (Tire Performance Criteria) specification system, which includes specific requirements that ensure robust tire performance under normal usage. General Motors works with tire suppliers to design and manufacture original equipment tires for GM vehicles. The GM TPC addresses required performance with respect to both inflation pressure retention, and endurance properties for original equipment tires. The inflation pressure retention requirements address availability of oxygen and oxidation concerns, while endurance requirements ensure the mechanical structure of the tire has sufficient strength. This combination has provided our customers with tires that maintain their structural integrity throughout their useful treadlife under normal operating conditions. Regardless of the inflation media for tires (atmospheric air or nitrogen), inflation pressure maintenance of tires is critical for overall tire, and ultimately, vehicle performance. Maintaining the correct inflation pressure allows the tire to perform as intended by the vehicle manufacturer in many areas, including comfort, fuel economy, stopping distance, cornering, traction, treadwear, and noise. Since the load carrying capability of a tire is related to inflation pressure, proper inflation pressure maintenance is necessary for the tire to support the load imposed by the vehicle without excessive structural Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 05-03-10-020C > Apr > 10 > Wheels/Tires - Use of Nitrogen Gas in Tires > Page 3253 degradation.

Customer Concerns and Confusion with the Tire Pressure Monitoring (TPM) System The following procedure should be used by dealership service consultants when a customer comes into the service drive with a "low tire light" on or comments on a check tire pressure/low tire pressure/add air to tire or service tire monitor system message. The service consultant should perform the following steps: Procedure Turn the key to ON, without starting the engine. ^ If the low tire light comes on and stays on solid with a check tire pressure/low tire pressure/add air to tire message (on vehicles equipped with DIC), advise the customer: - The system is working properly. - Properly adjusting all tire air pressures to the recommended levels and driving the vehicle will turn the light off (refer to the Tire and Loading Information label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". ^ If the Tire Pressure Monitor (TPM) light blinks for one minute then stays on solid with a service tire monitor system message (on vehicles equipped with DIC): - A TPM system problem exists. The vehicle should be written up accordingly and sent to your service department for further DTC diagnosis and service. - If dashes (--) are displayed in only one or two of the tire pressure readouts, it is likely caused by a previous TPM system relearn that was performed incorrectly due to interference from another vehicle's TPM system during the relearn process (refer to the Important statement later in this bulletin regarding TPM relearn with a Tech 2(R)). - If dashes (--) are displayed in all four of the tire pressure readouts, there is a system problem. Follow the appropriate SI service procedures. ^ If a customer indicates the low tire light comes on for a few minutes when the vehicle is started, then goes off after driving a while, advise the customer: - The system is working properly. - Most likely, air pressure in one or more of the tires is low enough to turn the light on when tires are cold. After driving for a while, tires will heat Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 09-03-16-002A > Apr > 10 > Tire Pressure Monitor - TPM System Message/Service Tips > Page 3258 up, allowing tire air pressure to increase above the threshold causing the light to go off. Properly adjusting all tire air pressures to the recommended levels will correct this (Refer to the Tire and Loading Information Label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". For more detailed information, refer to Corporate Bulletin Number 07-03-16-004C and TPMS Training Course 13044.12T2. Tire Pressure Light At key on, without starting the vehicle: Steady Solid Glowing TPM Indicator If the TPM indicator appears as a steady glowing yellow lamp (as above), the system is functioning properly and you should add air to the tires to correct this condition. Blinking TPM Indicator If the TPM indicator appears as a BLINKING yellow lamp for one minute and then stays on solid, diagnostic service is needed. The Effect of Outside Temperature on Tire Pressures Important: As a rule of thumb, tire pressure will change about 7kPa (1 psi) for every 6°C (10°F) decrease in temperature - Tire pressure will drop when it gets colder outside, and rise when it gets warmer. Under certain situations such as extreme outside temperature changes, the system may bring on a solid light with a check tire pressure message. This should be considered normal and the system is working properly. The light will turn off upon adding the proper amount of air to the tires (refer to the Tire & Loading Information label in the driver's door opening). When properly adjusting tire air pressure, the following steps are important to help optimize the system and prolong bringing a tire pressure light on: ^ Use an accurate, high quality tire pressure gauge. ^ Never set the tire pressure below the specified placard value regardless of tire temperature or ambient temperature. ^ Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will encounter during operation. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 09-03-16-002A > Apr > 10 > Tire Pressure Monitor - TPM System Message/Service Tips > Page 3259 ^ When adding proper tire air pressure, it is important to remember fluctuations in outside air temperatures and tire temperatures effect tire air pressures. ^ After you have added the proper tire pressure, if the vehicle has a DIC (after the system has updated), check to see if DIC displays are the same readings as the tire pressure gauge used (adjust as necessary). ^ Only perform a TPM sensor re-learn after a tire rotation or system part replacements and use the Tech 2(R) to initiate the relearn whenever possible to avoid invalid sensor I.D. learns. Important: Always take outside temperature and tire temperature into consideration to properly set tire pressures. Foe example, on colder days (20°F/-7°C), if setting tire pressure when the vehicle has been indoors (60°F/16°C) or the tires are warm from being driven, it will be necessary to compensate for the low outside temperature by adding 21-27 kPa (3-4 psi) more then the placecard pressure. At some later time, when the vehicle has been parked outside for a while, the tires will cool off and the pressures will drop back into the placecard range. Important: Recently, nitrogen gas (for use in inflating tires) has become available to the general customer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. Tires inflated with nitrogen gas may exhibit less of a pressure change in response to outside temperature changes. Nitrogen gas inflation is compatible with GM TPM sensors. For additional information, refer to Corporate Service Bulletin 05-03-10-020C. Important: All Models (Except the Pontiac Vibe): Do not perform a TPM relearn at PDI, the system has already been set at the Assembly Plant. Do not perform a TPM relearn after adding air to the tires. The low tire light is similar to the low fuel indicator and adding something (fuel, air) to the vehicle makes that light turn back off again. Note that because of system behavior, some vehicles must be driven a short distance before the sensors recognize the increase in pressure and turns the light off again. Pontiac Vibe Only: Do not use the TPMS reset button to turn off the light. The system will update and light will turn off when all tire pressures have been adjusted followed by short distance drive. Important: All models (except the Pontiac Vibe): Each tire monitor sensor is learned to a specific vehicle corner. When performing a TPM relearn (only after a tire rotation or replacement of a TPM sensor or Module), always use the Tech2(R) to initiate the J 46079 relearned process. Tech 2(R) - initiated relearns lock out other vehicle TPM signals that may be broadcasting in the area. Only signals initiated by the J 46079 tool will be accepted. This method avoids storing false TPM I.D.s and will prevent customers from returning with dashes (--) displayed in tire pressure readouts and/or a flashing tire pressure monitor (TPM) light. Checking the four TPM I.D.s with the Tech 2(R) prior to and following relearn to verify they are the same can prevent invalid I.D. learns. Pontiac Vibe Only: Tire Monitor Sensors are not learned to a specific vehicle corner. Do not perform a TPM Reset after tire rotation. The TPMS Reset button must only be used during pre-delivery inspection by the dealer to initialize the system (after all tire pressures have been adjusted properly) or when a Tire Pressure Monitor System component is replaced. The J 46079 tool does not work on Vibe TPM sensors. A TPMS relearn on Vibe must be preformed with a Tech 2(R) to set the TPMS Module in learn mode. The TPMS sensor IDs are entered through the Tech 2(R). Refer to SI for further Vibe TPMS information. Labor Operation and Repair Order/Warranty System Claim Required Documentation Important: The ONLY time labor operation E0726 or E0722 should be used is to diagnose for a system issue. That should ONLY occur if, at key ON, without starting the engine, the Tire Pressure Monitor (TPM) blinks for one minute and then stays on solid with a Service Tire Monitor System message (on vehicles equipped with a DIC) If that occurs, a TPM system problem exists and the system will have set a DTC. If one of these operastions is used, the following Repair Order and Warranty System documentation are required: ^ Document the customer complaint on the Repair Order. ^ Document the TPMS DTC that has set on the Repair Order. ^ Enter the TPMS DTC in the Warranty System (WINS) in the Failure Code/DTC field on the claim submission (refer to the Claims Processing Manual, Section IV, Warranty claim Data, Page 6, Item G). If the above information is not documented on the Repair Order and Warranty System, the claim may be rejected. If the Warranty Parts Center (WPC) generates a request, this repair order documentation must be sent back.

Please discard Corporate Bulletin Number 07-03-10-008A (Section 03 - Suspension). This bulletin provides information regarding the normal tire wear condition of slight or mild tire feathering and recommended practices. If a vehicle comes into a dealership with a concern of slight or mild feathering-type wear on the tires, review with the customer their past tire rotation history. Tires should be rotated every 8,000 to 13,000 km (5,000 to 8,000 mi) for applicable vehicles with tires where a tire rotation is possible or recommended. Refer to Corporate Bulletin Number 05-03-10-015B for information on tire rotation for vehicles with different front/rear tire/wheel sizes. SOME TIRE FEATHERING IS A NORMAL PART OF TIRE WEAR AND THROUGH PROPER TIRE ROTATION AND INFLATION, THIS TIRE WEAR CAN BE MINIMIZED AND TIRE LIFE MAXIMIZED. If the customer has not rotated the tires within the last 8,000 to 13,000 km (5,000 to 8,000 mi), a tire rotation in the modified X-pattern is necessary to clean-up the feathering, rather than placing the vehicle on the alignment machine.

Important: ^ Adjustment of tire pressure for a customer with a Low Tire Pressure Monitor (TPM) light on and no codes in the TPM system is NOT a warrantable repair. Claims to simply adjust the tire pressure will be rejected. ^ ALL tires (including the spare tire) MUST be set to the recommended inflation pressure stated on the vehicle's tire placard (on driver's door) during the PRE-DELIVERY INSPECTION (PDI). Recommended inflation pressure is not the pressure printed on tire sidewall. ^ Tires may be over-inflated from the assembly plant due to the mounting process. ^ Generally a 5.6°C (10°F) temperature change will result in (is equivalent to) a 6.9 kPa (1 psi) tire pressure change. ^ 2008-2009 HUMMER H2 Only - The H2 comes standard with Light Truck "D" Load Range tires with a recommended cold inflation pressure of 289 kPa (42 psi). These tires will alert the driver to a low pressure situation at roughly 262 kPa (38 psi) due to a requirement in FMVSS 138 which specifies a Minimum Activation Pressure for each tire type. This creates a relatively narrow window of "usable" pressure values and the warning will be more sensitive to outside temperature changes during the colder months. As with other cold temperature/tire pressure issues, there is nothing wrong with the system itself. If a vehicle is brought in with this concern, check for tire damage and set all tires to the Recommended Cold Inflation Pressure shown on the vehicle placard. Accurate tire pressures ensure the safe handling and appropriate ride characteristics of GM cars and trucks. It is critical that the tire pressure be adjusted to the specifications on the vehicle¡C■s tire placard during PDI. Ride, handling and road noise concerns may be caused by improperly adjusted tire pressure. The first step in the diagnosis of these concerns is to verify that the tires are inflated to the correct pressures. The recommended tire inflation pressure is listed on the vehicle¡C■s tire placard. The tire placard is located on the driver¡C■s side front or rear door edge, center pillar, or the rear compartment lid. Tip ^ Generally a 5.6°C (10°F) temperature increase will result in (is equivalent to) a 6.9 kPa (1 psi) tire pressure increase. ^ The definition of a "cold" tire is one that has been sitting for at least 3 hours, or driven no more than 1.6 km (1 mi). ^ On extremely cold days, if the vehicle has been indoors, it may be necessary to compensate for the low external temperature by adding additional air to the tire during PDI. ^ During cold weather, the Tire Pressure Monitor (TPM) indicator light (a yellow horseshoe with an exclamation point) may illuminate. If this indicator turns off after the tires warm up (reach operating temperature), the tire pressure should be reset to placard pressure at the cold temperature. ^ The TPM system will work correctly with nitrogen in tires. ^ The TPM system is compatible with the GM Vehicle Care Tire Sealant but may not be with other commercially available sealants. Important: ^ Do not use the tire pressure indicated on the tire itself as a guide.

The driver information center (DIC), if equipped, will also display a SERVICE TIRE MONITOR type message. When the road tire is repaired and reinstalled in the original location, the TPM indicator icon illumination and DIC message may remain displayed until the DTC is cleared. To ensure that the TPM indicator and the DIC message are cleared after service, it is necessary to clear any TPM DTCs using a scan tool. If a scan tool is unavailable, performing the TPM relearn procedure using a TPM diagnostic tool will provide the same results. It is advised to perform the relearn procedure away from other vehicles to prevent picking up a stray sensor signal. If one or more of the TPM sensors are missing or damaged and have been replaced, then the relearn procedure must be performed.

GM's Position on the Use of Nitrogen Gas in Tires General Motors does not oppose the use of purified nitrogen as an inflation gas for tires. We expect the theoretical benefits to be reduced in practical use due to the lack of an existing infrastructure to continuously facilitate inflating tires with nearly pure nitrogen. Even occasional inflation with compressed atmospheric air will negate many of the theoretical benefits. Given those theoretical benefits, practical limitations, and the robust design of GM original equipment TPC tires, the realized benefits to our customer of inflating their tires with purified nitrogen are expected to be minimal. The Promise of Nitrogen: Under Controlled Conditions Recently, nitrogen gas (for use in inflating tires) has become available to the general consumer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. The following benefits under controlled conditions are attributed to nitrogen gas and its unique properties: - A reduction in the expected loss of Tire Pressure over time. - A reduction in the variance of Tire Pressures with temperature changes due to reduction of water vapor concentration. - A reduction of long term rubber degradation due to a decrease in oxygen concentrations.

Please discard Corporate Bulletin Number 04-03-10-001E (Section 03 - Suspension). This bulletin covers puncture repair procedures for passenger car and light duty truck radial tires in the tread area only. The tire manufacturer must be contacted for its individual repair policy and whether or not the speed rating is retained after repair. Caution - Tire changing can be dangerous and should be done by trained professionals using proper tools and procedures. Always read and understand any manufacturer's warnings contained in their customers literature or molded into the tire sidewall. - Serious eye and ear injury may result from not wearing adequate eye and ear protection while repairing tires. - NEVER inflate beyond 275 kPa (40 pounds) pressure to seat beads. Some run flat tires, such as the Goodyear Extended Mobility Tire (EMT) used on the Corvette, may require more than 275 kPa (40 psi) to seat the bead. In such a case, a tire safety cage must be used. Consult the tire manufacturer for its individual repair policy. - NEVER stand, lean or reach over the assembly during inflation. Repairable area on a radial tire. Important - NEVER repair tires worn to the tread indicators 1.59 mm (2/32") remaining depth). - NEVER repair tires with a tread puncture larger than 6.35 mm (1/4"). - NEVER substitute an inner tube for a permissible or non-permissible repair. - NEVER perform an outside-in tire repair (plug only, on the wheel). - Every tire must be removed from the wheel for proper inspection and repair. - Regardless of the type of repair used, the repair must seal the inner liner and fill the injury. - Consult with repair material supplier/manufacturer for repair unit application procedures and repair tools/repair material recommendations. Three basic steps for tire puncture repair: 1. Remove the tire from the wheel for inspection and repair. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > Page 3276 2. Fill the injury (puncture) to keep moisture out. 3. Seal the inner liner with a repair unit to prevent air loss. External Inspection 1. Prior to demounting, inspect the tire surface, the valve and the wheel for the source of the leak by using a water and soap solution. Mark the injured area and totally deflate the tire by removing the valve core. 2. Demount the tire from the wheel and place the tire on a well-lighted spreader. Internal Inspection 1. Spread the beads and mark the puncture with a tire crayon. 2. Inspect the inner tire for any signs of internal damage. 3. Remove the puncturing object, noting the direction of the penetration. 4. Probe the injury with a blunt awl in order to determine the extent and direction of the injury. 5. Remove any loose foreign material from the injury. 6. Punctures exceeding 6.35 mm (1/4") should not be repaired. Cleaning 1. Clean the area around the puncture thoroughly with a proper liner cleaner, clean cloth and a scraper. This step serves to remove dirt and mold lubricants to insure proper adhesion and non-contamination of the buffing tool. 2. Refer to information on the product or manufacturer's Material Safety Data Sheet and follow guidelines for handling and disposal. Clean the Injury Channel Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > Page 3277 1. Use a proper hand reamer, carbide cutter or drill bit to ream the puncture channel from the inside of the tire in order to clean the injury. 2. Remove steel wires protruding above the liner surface to prevent damage to the repair unit. 3. Consult your repair material supplier for recommended reaming tool(s). Fill the Injury 1. It is necessary to fill the injury channel to provide back up for the repair unit and to prevent moisture from entering the tire fabric and steel wires. 2. (For combination repair/plug units skip this step.) Cement the injured channel and fill the injury from the inside of the tire with the repair plug per repair material manufacturer's recommendations. Without stretching the plug, cut the plug off just above the inside tire surface. 3. Consult your repair material supplier for proper repair material selection. Repair Unit Selection Important Do not install the repair unit in this step. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > Page 3278 1. Center the repair unit over the injury as a reference and outline an area larger than the unit so that buffing will not remove the crayon marks. 2. Remove the repair unit. 3. DO NOT overlap previous or multiple repair units. 4. Consult your repair material supplier for proper repair unit selection. Buffing 1. To prevent contamination and preserve the outline, buff within the marked area thoroughly and evenly with a low speed buffing tool using a fine wire brush or gritted rasp. 2. Buff to a smooth velvet surface (RMA #1 or #2 buffed texture). 3. Use caution not to gouge the inner liner or expose casing fabric. 4. Remove any buffing dust with a vacuum cleaner. 5. Consult your repair material supplier for a proper buffing tool. Cementing Apply chemical cement according to the repair material manufacturer's procedures. Repair Unit Application Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > Page 3279 1.

Incorrect tire pressures, or under-inflated tires, can cause the following conditions: * Vehicle handling concerns * Poor fuel economy * Shortened tire life * Tire overloading Inspect the tire pressure when the following conditions apply: * The vehicle has been sitting at least 3 hours. * The vehicle has not been driven for more than 1.6 km (1 mi). * The tires are cool. Inspect the tires monthly or before any extended trip. Adjust the tire pressure to the specifications on the tire label. Install the valve caps or the extensions on the valves. The caps or the extensions keep out dust and water. The kilopascal (kPa) is the metric term for pressure. The tire pressure may be printed in both kilopascal (kPa) and psi. One psi equals 6.9 kPa. Inflation Pressure Conversation (Kilopascals To PSI) Tires with a higher than recommended pressure can cause the following conditions: * A hard ride * Tire bruising * Rapid tread wear at the center of the tire Tires with a lower than recommended pressure can cause the following conditions: * A tire squeal on turns * Hard steering * Rapid wear and uneven wear on the edge of the tread * Tire rim bruises and tire rim rupture * Tire cord breakage * High tire temperatures * Reduced vehicle handling * High fuel consumption * Soft riding Unequal pressure on the same axle can cause the following conditions: Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Description and Operation > Tread Wear Indicators Description > Page 3284 * Uneven braking * Steering lead * Reduced vehicle handling Refer to the Tire Placard for specific tire and wheel applications and tire pressures.

Three basic steps for tire puncture repair: 1. Remove the tire from the wheel for inspection and repair. 2. Fill the injury (puncture) to keep moisture out. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 3289 3. Seal the inner liner with a repair unit to prevent air loss. External Inspection 1. Prior to demounting, inspect the tire surface, the valve and the wheel for the source of the leak by using a water and soap solution. Mark the injured area and totally deflate the tire by removing the valve core. 2. Demount the tire from the wheel and place the tire on a well-lighted spreader. Internal Inspection 1. Spread the beads and mark the puncture with a tire crayon. 2. Inspect the inner tire for any signs of internal damage. 3. Remove the puncturing object, noting the direction of the penetration. 4. Probe the injury with a blunt awl in order to determine the extent and direction of the injury. 5. Remove any loose foreign material from the injury. 6. Punctures exceeding 6.35 mm (1/4 in) should not be repaired. Cleaning Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 3290 1. Clean the area around the puncture thoroughly with a proper liner cleaner, clean cloth and a scraper. This step serves to remove dirt and mold lubricants to insure proper adhesion and non-contamination of the buffing tool. 2. Refer to information on the product or manufacturer's Material Safety Data Sheet and follow guidelines for handling and disposal. Clean the Injury Channel 1. Use a proper hand reamer, carbide cutter or drill bit to ream the puncture channel from the inside of the tire in order to clean the injury. 2. Remove steel wires protruding above the liner surface to prevent damage to the repair unit. 3. Consult your repair material supplier for recommended reaming tool(s). Fill the Injury Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 3291 1. It is necessary to fill the injury channel to provide back up for the repair unit and to prevent moisture from entering the tire fabric and steel wires. 2. For combination repair/plug units skip this step. Cement the injured channel and fill the injury from the inside of the tire with the repair plug per repair material manufacturer's recommendations. Without stretching the plug, cut the plug off just above the inside tire surface. 3. Consult your repair material supplier for proper repair material selection. Repair Unit Selection Important: Do not install the repair unit in this step. 1. Center the repair unit over the injury as a reference and outline an area larger than the unit so that buffing will not remove the crayon marks. 2. Remove the repair unit. 3. DO NOT overlap previous or multiple repair units. 4. Consult your repair material supplier for proper repair unit selection. Buffing Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 3292 1. To prevent contamination and preserve the outline, buff within the marked area thoroughly and evenly with a low speed buffing tool using a fine wire brush or gritted rasp. 2. Buff to a smooth velvet surface (RMA #1 or #2 buffed texture). 3. Use caution not to gouge the inner liner or expose casing fabric. 4. Remove any buffing dust with a vacuum cleaner. 5. Consult your repair material supplier for a proper buffing tool. Cementing Apply chemical cement according to the repair material manufacturer's procedures.

After remounting and inflating the tire, check both beads, the repair and the valve with a water and soap solution in order to detect leaks. 2. If the tire continues to lose air, the tire must be demounted and reinspected. 3. Balance the tire and wheel assembly. Refer to Tire and Wheel Assembly Balancing - Off Vehicle. Tire Rotation Tire Rotation Rotate the tires and wheels at frequent intervals to equalize wear. Refer to Maintenance Schedule (North American Emissions). In addition to scheduled rotation, rotate the tire and wheel whenever uneven tire wear is noticed. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 3295 Radial tires tend to wear faster in the shoulder area, particularly in front positions. Radial tires in non-drive locations may develop an irregular wear pattern that may increase tire noise. This makes regular rotation especially necessary. Refer to Tire and Wheel Removal and Installation. Always use a 4-wheel rotation. After rotation, check the wheel nuts for specified torque. Then, set the tire pressure. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 3296 Tires: Removal and Replacement Tire Mounting and Dismounting Notice: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result. Notice: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel. Notice: Damage to either the tire bead or the wheel mounting holes can result from the use of improper wheel attachment or tire mounting procedures. It takes up to 70 seconds for all of the air to completely exhaust from a large tire. Failure to follow the proper procedures could cause the tire changer to put enough force on the tire to bend the wheel at the mounting surface. Such damage may result in vibration and/or shimmy, and under severe usage lead to wheel cracking. 1. Deflate the tire completely. Important: Rim-clamp European-type tire changers are recommended. 2. Use the tire changer in order to remove the tire from the wheel. 3. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats. Notice: When mounting the tires, use an approved tire mounting lubricant. DO NOT use silicon or corrosive base compounds to lubricate the tire bead and the wheel rim. A silicon base compound can cause the tire to slip on the rim. A corrosive type compound can cause tire or rim deterioration. 4. Apply an approved Lubricant to the tire bead and the wheel rim. 5. Use the tire changer in order to install the tire to the wheel. Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, relubricate the beads and reinflate. Overinflation may cause the bead to break and cause serious personal injury. 6. Inflate the tire to the proper air pressure. 7. Ensure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.

Please discard Corporate Bulletin Number 00-03-10-006E (Section 03 - Suspension). Important - Before measuring tires on equipment such as the Hunter GSP9700, the vehicle MUST be driven a minimum of 16 km (10 mi) to ensure removal of any flat-spotting. Refer to Corporate Bulletin Number 03-03-10-007E - Tire/Wheel Characteristics of GM Original Equipment Tires. - Equipment such as the Hunter GSP9700 MUST be calibrated prior to measuring tire/wheel assemblies for each vehicle. The purpose of this bulletin is to provide guidance to GM dealers when using tire force variation measurement equipment, such as the Hunter GSP9700. This type of equipment can be a valuable tool in diagnosing vehicle ride concerns. The most common ride concern involving tire radial force variation is highway speed shake on smooth roads. Tire related smooth road highway speed shake can be caused by three conditions: imbalance, out of round and tire force variation. These three conditions are not necessarily related. All three conditions must be addressed. Imbalance is normally addressed first, because it is the simpler of the three to correct. Off-vehicle, two plane dynamic wheel balancers are readily available and can accurately correct any imbalance. Balancer calibration and maintenance, proper attachment of the wheel to the balancer, and proper balance weights, are all factors required for a quality balance. However, a perfectly balanced tire/wheel assembly can still be "oval shaped" and cause a vibration. Before balancing, perform the following procedures. Tire and Wheel Diagnosis 1. Set the tire pressure to the placard values. 2. With the vehicle raised, ensure the wheels are centered on the hub by loosening all wheel nuts and hand-tightening all nuts first by hand while shaking the wheel, then torque to specifications using a torque wrench, NOT a torque stick. 3. Visually inspect the tires and the wheels. Inspect for evidence of the following conditions and correct as necessary: - Missing balance weights - Bent rim flange - Irregular tire wear - Incomplete bead seating - Tire irregularities (including pressure settings) - Mud/ice build-up in wheel - Stones in the tire tread - Remove any aftermarket wheels and/or tires and restore vehicle to original condition prior to diagnosing a smooth road shake condition. 4. Road test the vehicle using the Electronic Vibration Analyzer (EVA) essential tool. Drive for a sufficient distance on a known, smooth road surface to duplicate the condition. Determine if the vehicle is sensitive to brake apply. If the brakes are applied lightly and the pulsation felt in the steering wheel increases, refer to the Brakes section of the service manual that deals with brake-induced pulsation. If you can start to hear the vibration as a low boom noise (in addition to feeling it), but cannot see it, the vehicle likely has a first order (one pulse per propshaft revolution) driveline vibration. Driveline first order vibrations are high enough in frequency that most humans can start to hear them at highway speeds, but are too high to be able to be easily seen. These issues can be caused by driveline imbalance or misalignment. If the vehicle exhibits this low boom and the booming pulses in-and-out on a regular basis (like a throbbing), chances are good that the vehicle could have driveline vibration. This type Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > Customer Interest: > 00-03-10-006F > May > 10 > Wheels/Tires - Tire Radial Force Variation (RFV) > Page 3305 of vibration is normally felt more in the "seat of the pants" than the steering wheel. 5. Next, record the Hertz (Hz) reading as displayed by the EVA onto the tire data worksheet found at the end of this bulletin. This should be done after a tire break-in period of at least 16 km (10 mi) at 72 km/h (45 mph) or greater, in order to eliminate any possible tire flat-spotting. This reading confirms what the vehicle vibration frequency is prior to vehicle service and documents the amount of improvement occurring as the result of the various steps taken to repair. Completing the Steering Wheel Shake Worksheet below is required. A copy of the completed worksheet must be saved with the R.O. and a copy included with any parts returned to the Warranty Parts Center for analysis. A reading of 35 to 50 Hz typically indicates a first order propshaft vibration. If this is the situation, refer to Corporate Bulletin Number 08-07-30-044D. Generally, a reading between 10 and 20 Hz indicates a tire/wheel vibration and if this is the reading obtained, continue using this bulletin. If the tire 1st order vibration goes away and stays away during this evaluation, the cause is likely tire flat-spotting. Tire flat-spotting vibration may come and go at any speed over 72 km/h (45 mph) during the first 10 minutes of operation, if vibration continues after 10 minutes of driving at speeds greater than 72 km/h (45 mph), tire flat-spotting can be ruled out as the cause for vibration. 6. If flat-spotting is the cause, provide the explanation that this has occurred due to the vehicle being parked for long periods of time and that the nature of the tire is to take a set. Refer to Corporate Bulletin Number 03-03-10-007E: Information on Tire/Wheel Characteristics (Vibration, Balance, Shake, Flat Spotting) of GM Original Equipment Tires. 7. If the road test indicates a shake/vibration exists, check the imbalance of each tire/wheel assembly on a known, calibrated, off-car dynamic balancer.Make sure the mounting surface of the wheel and the surface of the balancer are absolutely clean and free of debris. Be sure to chose the proper cone/collet for the wheel, and always use the pilot bore for centering. Never center the wheel using the hub-cap bore since it is not a precision machined surface. If any assembly calls for more than 1/4 ounce on either rim flange, remove all balance weights and rebalance to as close to zero as possible. If you can see the vibration (along with feeling it) in the steering wheel (driving straight without your hands on the wheel), it is very likely to be a tire/wheel first order (one pulse per revolution) disturbance. First order disturbances can be caused by imbalance as well as non-uniformities in tires, wheels or hubs. This first order frequency is too low for a human to hear, but if the amplitude is high enough, it can be seen. If a vibration or shake still exists after balancing, any out of round conditions, of the wheel, and force variation conditions of the tire, must be addressed. Equipment such as the Hunter GSP9700 can address both (it is also a wheel balancer). Tire radial force vibration (RFV) can be defined as the amount of stiffness variation the tire will produce in one revolution under a constant load. Radial force variation is what the vehicle feels because the load (weight) of the vehicle is always on the tires. Although free runout of tires (not under load) is not always a good indicator of a smooth ride, it is critical that total tire/wheel assembly runout be within specification. Equipment such as the Hunter GSP9700 loads the tire, similar to on the vehicle, and measures radial force variation of the tire/wheel assembly. Note that the wheel is affecting the tire's RFV measurement at this point. To isolate the wheel, its runout must be measured. This can be easily done on the Hunter, without the need to set up dial indicators. If the wheel meets the runout specification, the tire's RFV can then be addressed. After measuring the tire/wheel assembly under load, and the wheel alone, the machine then calculates (predicts) the radial force variation of the tire. However, because this is a prediction that can include mounting inaccuracies, and the load wheel is much smaller in diameter than used in tire production, this type of service equipment should NOT be used to audit new tires. Rather, it should be used as a service diagnostic tool to minimize radial force variation of the tire/wheel assembly. Equipment such as the Hunter GSP9700 does an excellent job of measuring wheel runout, and of finding the low point of the wheel (for runout) and the high point of the tire (for radial force variation). This allows the tire to be matched mounted to the wheel for lowest tire/wheel assembly force variation. The machine will simplify this process into easy steps. The following assembly radial force variation numbers should be used as a guide: When measuring RFV and match mounting tires perform the following steps. Measuring Wheel Runout and Assembly Radial Force Variation Important The completed worksheet at the end of this bulletin must be attached to the hard copy of the repair order. - Measure radial force variation and radial runout. - If a road force/balancing machine is used, record the radial force variation (RFV) on the worksheet at the end of this bulletin. It may be of benefit to have the lowest RFV assembly to the front left corner. If the machine is not available and the EVA data suggests there is an issue, swap the tire and wheel assemblies from the front to the back. Re-check on the EVA and if the problem still exists, test another vehicle to find tires that do not exhibit the same frequency and swap those tires onto the subject vehicle. - If a runout/balancing machine is used, record the radial runout of the tire/wheel assemblies on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies are more than.040 in (1.02 mm), match mount the tire to the wheel to get below.040 in (1.02 mm). For sensitive customers, readings of 0.030 inch (0.76 mm) or less are preferable, it may also be of benefit to have the lowest runout assembly to the front left corner. If the machine is not available and the EVA data suggests there is an issue, swap the tire and wheel assemblies from the front to the back. Re-check on the EVA and if the problem still exists, test another vehicle to find tires that do not exhibit the same frequency and swap those tires Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > Customer Interest: > 00-03-10-006F > May > 10 > Wheels/Tires - Tire Radial Force Variation (RFV) > Page 3306 onto the subject vehicle. - After match mounting, the tire/wheel assembly must be rebalanced. If match mounting tires to in-spec wheels produces assembly values higher than these, tire replacement may be necessary. Replacing tires at lower values will probably mean good tires are being condemned. Because tires can sometimes become temporarily flat-spotted, which will affect force variation, it is important that the vehicle be driven at least 16 km (10 mi) prior to measuring. Tire pressure must also be adjusted to the usage pressure on the vehicle's tire placard prior to measuring. Most GM vehicles will tolerate radial force variation up to these levels. However, some vehicles are more sensitive, and may require lower levels. Also, there are other tire parameters that equipment such as the Hunter GSP9700 cannot measure that may be a factor. In such cases, TAC should be contacted for further instructions. Important - When mounting a GM wheel to a wheel balancer/force variation machine, always use the wheel's center pilot hole. This is the primary centering mechanism on all GM wheels; the bolt holes are secondary. Usually a back cone method to the machine should be used. For added accuracy and repeatability, a flange plate should be used to clamp the wheel onto the cone and machine. This system is offered by all balancer manufacturers in GM's dealer program. - Any type of service equipment that removes tread rubber by grinding, buffing or truing is NOT recommended, and may void the tire warranty. However, tires may have been ground by the tire company as part of their tire manufacturing process. This is a legitimate procedure.

Please discard Corporate Bulletin Number 08-03-10-006B (Section 03 - Suspension). Condition Some customers may comment on a tire that slowly loses air pressure over a period of days or weeks. Cause Abrasive elements in the environment may intrude between the tire and wheel at the bead seat. There is always some relative motion between the tire and wheel (when the vehicle is driven) and this motion may cause the abrasive particles to wear the wheel and tire materials. As the wear continues, there may also be intrusion at the tire/wheel interface by corrosive media from the environment. Eventually a path for air develops and a 'slow' leak may ensue. This corrosion may appear on the inboard or outboard bead seating surface of the wheel. This corrosion will not be visible until the tire is dismounted from the wheel. Notice This bulletin specifically addresses issues related to wheel bead seat corrosion that may result in an air leak. For issues related to porosity of the wheel casting that may result in an air leak, please refer to Corporate Bulletin Number 05-03-10-006F - Low Tire Pressure, Leaking Cast Aluminum Wheels (Repair with Adhesive Sealant) Correction In most cases, this type of air loss can be corrected by following the procedure below. Important DO NOT replace a wheel for slow air loss unless you have evaluated and/or tried to repair the wheel with the procedure below. Notice The repair is no longer advised or applicable for chromed aluminum wheels. 1. Remove the wheel and tire assembly for diagnosis. Refer to Tire and Wheel Removal and Installation in SI. 2. After a water dunk tank leak test, if you determine the source of the air leak to be around the bead seat of the wheel, dismount the tire to examine the bead seat. Shown below is a typical area of bead seat corrosion.Typical Location of Bead Seat Corrosion Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > Customer Interest: > 08-03-10-006C > Apr > 10 > Tires/Wheels - Tire Slowly Goes Flat/Warning Light ON > Page 3317 Important Other forms of slow air leaks are possible. If the body of the tire, valve stem and wheel flange show no signs of air seepage, refer to Corporate Bulletin Number 05-03-10-003D for additional information on possible wheel porosity issues. 3. Bead seat corrosion is identified by what appears like blistering of the wheel finish, causing a rough or uneven surface that is difficult for the tire to maintain a proper seal on. Below is a close-up photo of bead seat corrosion on an aluminum wheel that was sufficient to cause slow air loss. Close-Up of Bead Seat Corrosion 4. If corrosion is found on the wheel bead seat, measure the affected area as shown below. - For vehicles with 32,186 km (20,000 mi) or less, the total allowable combined linear area of repairable corrosion is 100 mm (4 in) or less. If the total area(s) of corrosion exceed these dimensions, the wheel should be replaced. - For vehicles that have exceeded 32,186 km (20,000 mi), the total allowable combined linear area of repairable corrosion is 200 mm (8 in) or less. If the total area(s) of corrosion exceed these dimensions, the wheel should be replaced. 5. In order to correct the wheel leak, use a clean-up (fine cut) sanding disc or biscuit to remove the corrosion and any flaking paint. You should remove the corrosion back far enough until you reach material that is stable and firmly bonded to the wheel. Try to taper the edge of any flaking paint as best you can in order to avoid sharp edges that may increase the chance of a leak reoccurring. The photo below shows an acceptable repaired surface. Notice Corrosion that extends up the lip of the wheel, where after the clean-up process it would be visible with the tire mounted, is only acceptable on the inboard flange. The inboard flange is not visible with the wheel assembly in the mounted position. If any loose coatings or corrosion extend to the visible surfaces on the FACE of the wheel, that wheel must be replaced. Important Remove ONLY the material required to eliminate the corrosion from the bead seating surface. DO NOT remove excessive amounts of material. ALWAYS keep the sealing surface as smooth and level as possible.

Once the corrosion has been eliminated, you should coat the repaired area with a commercially available tire sealant such as Patch Brand Bead Sealant or equivalent. Commercially available bead sealants are black rubber-like coatings that will permanently fill and seal the resurfaced bead seat. At 21°C (70°F) ambient temperature, this sealant will set-up sufficiently for tire mounting in about 10 minutes.Coated and Sealed Bead Seat 7. Remount the tire and install the repaired wheel and tire assembly. Refer to Tire and Wheel Removal and Installation in SI.

Figure 1 Chemical staining in most cases results from acid based cleaners (refer to Figure 1 for an example). These stains are frequently milky, black, or greenish in appearance. They result from using cleaning solutions that contain acids on chrome wheels. Soap and water is usually sufficient to clean wheels. If the customer insists on using a wheel cleaner they should only use one that specifically states that it is safe for chromed wheels and does not contain anything in the following list. (Dealers should also survey any products they use during prep or normal cleaning of stock units for these chemicals.) - Ammonium Bifluoride (fluoride source for dissolution of chrome) - Hydrofluoric Acid (directly dissolves chrome) - Hydrochloric Acid (directly dissolves chrome) - Sodium Dodecylbenzenesulfonic Acid - Sulfamic Acid - Phosphoric Acid - Hydroxyacetic Acid Notice Many wheel cleaner instructions advise to take care to avoid contact with painted surfaces. Most customers think of painted surfaces as the fenders, quarter panels and other exterior sheet metal. Many vehicles have painted brake calipers. Acidic wheel cleaners may craze, crack, or discolor the paint on the brake calipers. Damage from wheel cleaners is not covered under the vehicle new car warranty. Soap and water applied with a soft brush is usually all that is required to clean the calipers. Whenever any wheel cleaner is used, it must be THOROUGHLY rinsed off of the wheel with clean, clear water. Special care must be taken to rinse under the hub cap, balance weights, wheel nuts, lug nut caps, between the wheel cladding and off the back side of the wheel. Wheels returned to the Warranty Parts Center (WPC) that exhibit damage from wheel cleaners most often have the damage around and under the wheel weight where the cleaner was incompletely flushed away. Notice Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Wheels: > 00-03-10-002F > Apr > 11 > Wheels - Chrome Wheel Staining/Pitting/Corrosion > Page 3325 Do not use cleaning solutions that contain hydrofluoric, oxalic and most other acids on chrome wheels (or any wheels). If the customer is unsure of the chemical make-up of a particular wheel cleaner, it should be avoided. For wheels showing signs of milky staining from acidic cleaners, refer to Customer Assistance and Instructions below. Warranty of Stained Chrome Wheels Stained wheels are not warrantable. Most acid based cleaners will permanently stain chrome wheels. Follow-up with dealers has confirmed that such cleaners were used on wheels that were returned to the Warranty Parts Center (WPC). Any stained wheels received by the WPC will be charged back to the dealership. To assist the customer, refer to Customer Assistance and Instructions below. Pitting or Spotted Appearance of Chrome Wheels Figure 2 A second type or staining or finish disturbance may result from road chemicals, such as calcium chloride used for dust control of unpaved roads. The staining will look like small pitting (refer to Figure 2). This staining will usually be on the leading edges of each wheel spoke, but may be uniformly distributed. If a vehicle must be operated under such conditions, the chrome wheels should be washed with mild soap and water and thoroughly rinsed as soon as conveniently possible. Important Road chemicals, such as calcium chloride used for dust control of unpaved roads, can also stain chrome wheels. The staining will look like small pitting. This staining will usually be on the leading edges of each wheel spoke. This is explained by the vehicle traveling in the forward direction while being splashed by the road chemical. If a vehicle must be operated under such conditions, the chrome wheels should be washed with mild soap and water and thoroughly rinsed as soon as conveniently possible. Warranty of Pitted or Spotted Chrome Wheels Wheels returned with pitting or spotting as a result of road chemicals may be replaced one time. Damage resulting from contact with these applied road chemicals is corrosive to the wheels finish and may cause damage if the wheels are not kept clean. Important Notify the customer that this is a one time replacement. Please stress to the customer the vital importance of keeping the wheels clean if they are operating the vehicle in an area that applies calcium chloride or other dust controlling chemicals! "GM of Canada" dealers require prior approval by the District Manager - Customer Care and Service Process (DM-CCSP). "Stardust" Corrosion of Chrome Wheels Figure 3 A third type of finish disturbance results from prolonged exposure to brake dust and resultant penetration of brake dust through the chrome. As brakes are applied hot particles of brake material are thrown off and tend to be forced through the leading edge of the wheel spoke windows by airflow. These Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Wheels: > 00-03-10-002F > Apr > 11 > Wheels - Chrome Wheel Staining/Pitting/Corrosion > Page 3326 hot particles embed themselves in the chrome layer and create a small pit. If the material is allowed to sit on the wheel while it is exposed to moisture or salt, it will corrode the wheel beneath the chrome leaving a pit or small blister in the chrome. Heavy brake dust build-up should be removed from wheels by using GM Chrome Cleaner and Polish, P/N 1050173 (in Canada use 10953013). For moderate cleaning, light brake dust build-up or water spots use GM Swirl Remover Polish, P/N 12377965 (in Canada, use Meguiars Plast-X(TM) Clear Plastic Cleaner and Polish #G12310C**). After cleaning, the wheel should be waxed using GM Cleaner Wax, P/N 12377966 (in Canada, use Meguiars Cleaner Wax #M0616C**), which will help protect the wheel from brake dust and reduce adhesion of any brake dust that gets on the wheel surface. For general maintenance cleaning, PEEK Metal Polish† may be used. It will clean and shine the chrome and leave behind a wax coating that may help protect the finish. Warranty of Stardust Corroded Chrome Wheels Wheels returned with pitting or spotting as a result of neglect and brake dust build-up may be replaced one time. Important Notify the customer that this is a one time replacement. Please stress to the customer the vital importance of keeping the wheels clean and free of prolonged exposure to brake dust build-up. "GM of Canada" dealers require prior approval by the District Manager - Customer Care and Service Process (DM-CCSP). Customer Assistance and Instructions GM has looked for ways customers may improve the appearance of wheels damaged by acidic cleaners. The following product and procedure has been found to dramatically improve the appearance of stained wheels. For wheels that have milky stains caused by acidic cleaners try the following: Notice THE 3M CHROME AND METAL POLISH REQUIRED FOR THIS PROCEDURE IS AN EXTREMELY AGGRESSIVE POLISH/CLEANER. THE WHEELS MUST BE CLEANED BEFORE APPLICATION TO AVOID SCRATCHING THE WHEEL SURFACE. THIS PRODUCT WILL REDUCE THE THICKNESS OF THE CHROME PLATING ON THE WHEEL AND IF USED INCORRECTLY OR EXCESSIVELY MAY REMOVE THE CHROME PLATING ALL TOGETHER, EXPOSING A LESS BRIGHT AND BRASSY COLORED SUB-LAYER. FOLLOW INSTRUCTIONS EXACTLY. 1. Wash the wheels with vigorously with soap and water. This step will clean and may reduce wheel staining. Flood all areas of the wheel with water to rinse. 2. Dry the wheels completely. Notice Begin with a small section of the wheel and with light pressure buff off polish and examine results. ONLY apply and rub with sufficient force and time to remove enough staining that you are satisfied with the results. Some wheels may be stained to the extent that you may only achieve a 50% improvement while others may be able to be restored to the original lustre. IN ALL CASES, only apply until the results are satisfactory. 3. Apply 3M Chrome and Metal Polish #39527* with a clean terry cloth towel. As you apply the polish, the staining will be diminished. 4. When dry, buff off the polish with a clean portion of the towel. 5. Repeat application of the 3M Chrome and Metal Polish until satisfied with the results. If continued applications fail to improve the appearance further discontinue use. This procedure will improve the appearance of the wheels and may, with repeated applications, restore the finish dramatically. For wheels that exhibit spotting from road chemicals the above procedure may marginally improve the condition but will not restore the finish or remove the pitting. In this type of staining the wheel finish has actually been removed in spots and no manner of cleaning will restore the finish. †*We believe this source and their products to be reliable.

Please discard Corporate Bulletin Number 99-08-51-007D (Section 08 - Body and Accessories). This bulletin updates General Motor's position on refinishing aluminum wheels. GM does not endorse any repairs that involve welding, bending, straightening or re-machining. Only cosmetic refinishing of the wheel's coatings, using recommended procedures, is allowed. Evaluating Damage In evaluating damage, it is the GM Dealer's responsibility to inspect the wheel for corrosion, scrapes, gouges, etc. The Dealer must insure that such damage is not deeper than what can be sanded or polished off. The wheel must be inspected for cracks. If cracks are found, discard the wheel. Any wheels with bent rim flanges must not be repaired or refinished. Wheels that have been refinished by an outside company must be returned to the same vehicle. The Dealer must record the wheel ID stamp or the cast date on the wheel in order to assure this requirement. Refer to Refinisher's Responsibility - Outside Company later in this bulletin. Aluminum Wheel Refinishing Recommendations - Chrome-plated aluminum wheels Re-plating these wheels is not recommended. - Polished aluminum wheels These wheels have a polyester or acrylic clearcoat on them. If the clearcoat is damaged, refinishing is possible. However, the required refinishing process cannot be performed in the dealer environment. Refer to Refinisher's Responsibility - Outside Company later in this bulletin. - Painted aluminum wheels These wheels are painted using a primer, color coat, and clearcoat procedure. If the paint is damaged, refinishing is possible. As with polished wheels, all original coatings must be removed first. Media blasting is recommended. Refer to GM Aluminum Refinishing Bulletin #53-17-03A for the re-painting of this type of wheel. - Bright, machined aluminum wheels These wheels have a polyester or acrylic clearcoat on them. In some cases, the recessed "pocket" areas of the wheel may be painted. Surface refinishing is possible. The wheel must be totally stripped by media blasting or other suitable means. The wheel should be resurfaced by using a sanding process rather than a machining process. This allows the least amount of material to be removed. Important Do not use any re-machining process that removes aluminum. This could affect the dimensions and function of the wheel. Painting is an option to re-clearcoating polished and bright machined aluminum wheels. Paint will better mask any surface imperfections and is somewhat more durable than clearcoat alone. GM recommends using Corsican SILVER WAEQ9283 for a fine "aluminum-like" look or Sparkle SILVER WA9967 for a very bright look. As an option, the body color may also be used. When using any of the painting options, it is recommended that all four wheels be refinished in order to maintain color uniformity. Refer to GM Aluminum Refinishing Bulletin #53-17-03A for specific procedures and product recommendations. Refinisher's Responsibility - Outside Company Important Some outside companies are offering wheel refinishing services. Such refinished wheels will be permanently marked by the refinisher and are warranted by the refinisher. Any process that re-machines or otherwise re-manufactures the wheel should not be used. A refinisher's responsibility includes inspecting for cracks using the Zyglo system or the equivalent. Any cracked wheels must not be refinished. No welding, hammering or reforming of any kind is allowed. The wheel ID must be recorded and follow the wheel throughout the process in order to assure that the same wheel is returned. A plastic media blast may be used for clean up of the wheel. Hand and/or lathe sanding of the machined surface and the wheel window is allowed. Material removal, though, must be kept to a minimum. Re-machining of the wheel is not allowed. Paint and/or clear coat must not be present on the following surfaces: the nut chamfers, the wheel mounting surfaces and the wheel pilot hole. The refinisher must permanently ID stamp the wheel and warrant the painted/clearcoated surfaces for a minimum of one year or the remainder of the new vehicle warranty, whichever is Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Wheels: > 99-08-51-007E > Mar > 11 > Wheels/Tires - Refinishing Aluminum Wheels > Page 3332 longer. Important Whenever a wheel is refinished, the mounting surface and the wheel nut contact surfaces must not be painted or clearcoated. Coating these surfaces could affect the wheel nut torque. When re-mounting a tire on an aluminum wheel, coated balance weights must be used in order to reduce the chance of future cosmetic damage.

This bulletin is intended to quickly review and reinforce simple but vital procedures to reduce the possibility of achieving low torque during wheel installation. Always refer to SI for wheel lug nut torque specifications and complete jacking instructions for safe wheel changing. Supercede: This bulletin is being revised to include the 2011 model year and update the available special tool list. Please discard Corporate Bulletin Number 06-03-10-010 (Section 03 Suspension). Frequency of Wheel Changes - Marketplace Driven Just a few years ago, the increasing longevity of tires along with greater resistance to punctures had greatly reduced the number of times wheels were removed to basically required tire rotation intervals. Today with the booming business in accessory wheels/special application tires (such as winter tires), consumers are having tire/wheel assemblies removed - replaced - or installed more than ever. With this increased activity, it opens up more of a chance for error on the part of the technician. This bulletin will review a few of the common concerns and mistakes to make yourself aware of. Proper Servicing Starts With the Right Tools The following tools have been made available to assist in proper wheel and tire removal and installation. - J 41013 Rotor Resurfacing Kit (or equivalent) - J 42450-A Wheel Hub Resurfacing Kit (or equivalent) Corroded Surfaces One area of concern is corrosion on the mating surfaces of the wheel to the hub on the vehicle. Excessive corrosion, dirt, rust or debris built up on these surfaces can mimic a properly tightened wheel in the service stall. Once the vehicle is driven, the debris may loosen, grind up or be washed away from water splash. This action may result in clearance at the mating surface of the wheel and an under-torqued condition. Caution Before installing a wheel, remove any buildup on the wheel mounting surface and brake drum or brake disc mounting surface. Installing wheels with poor metal-to-metal contact at the mounting surfaces can cause wheel nuts to loosen. This may cause a wheel to come off when the vehicle is moving, possibly resulting in a loss of control or personal injury. Whenever you remove the tire/wheel assemblies, you must inspect the mating surfaces. If corrosion is found, you should remove the debris with a die grinder equipped with a fine sanding pad, wire brush or cleaning disc. Just remove enough material to assure a clean, smooth mating surface. The J 41013 (or equivalent) can be used to clean the following surfaces: - The hub mounting surface - The brake rotor mounting surface - The wheel mounting surface Use the J 42450-A (or equivalent) to clean around the base of the studs and the hub. Lubricants, Grease and Fluids Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Wheels: > 06-03-10-010A > Jun > 10 > Wheels - Changing Procedures/Precautions > Page 3337 Some customers may use penetrating oils, grease or other lubricants on wheel studs to aid in removal or installation. Always use a suitable cleaner/solvent to remove these lubricants prior to installing the wheel and tire assemblies. Lubricants left on the wheel studs may cause improper readings of wheel nut torque. Always install wheels to clean, dry wheel studs ONLY. Notice Lubricants left on the wheel studs or vertical mounting surfaces between the wheel and the rotor or drum may cause the wheel to work itself loose after the vehicle is driven. Always install wheels to clean, dry wheel studs and surfaces ONLY. Beginning with 2011 model year vehicles, put a light coating of grease, GM P/N 1051344 (in Canada, P/N 9930370), on the inner surface of the wheel pilot hole to prevent wheel seizure to the axle or bearing hub. Wheel Stud and Lug Nut Damage Always inspect the wheel studs and lug nuts for signs of damage from crossthreading or abuse. You should never have to force wheel nuts down the stud. Lug nuts that are damaged may not retain properly, yet give the impression of fully tightening. Always inspect and replace any component suspected of damage. Tip Always start wheel nuts by hand! Be certain that all wheel nut threads have been engaged BEFORE tightening the nut. Important If the vehicle has directional tread tires, verify the directional arrow on the outboard side of the tire is pointing in the direction of forward rotation. Wheel Nut Tightening and Torque Improper wheel nut tightening can lead to brake pulsation and rotor damage. In order to avoid additional brake repairs, evenly tighten the wheel nuts to the proper torque specification as shown for each vehicle in SI. Always observe the proper wheel nut tightening sequence as shown below in order to avoid trapping the wheel on the wheel stud threads or clamping the wheel slightly off center resulting in vibration. The Most Important Service You Provide While the above information is well known, and wheel removal so common, technicians run the risk of becoming complacent on this very important Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Wheels: > 06-03-10-010A > Jun > 10 > Wheels - Changing Procedures/Precautions > Page 3338 service operation. A simple distraction or time constraint that rushes the job may result in personal injury if the greatest of care is not exercised. Make it a habit to double check your work and to always side with caution when installing wheels.

Please discard Corporate Bulletin Number 00-03-10-006E (Section 03 - Suspension). Important - Before measuring tires on equipment such as the Hunter GSP9700, the vehicle MUST be driven a minimum of 16 km (10 mi) to ensure removal of any flat-spotting. Refer to Corporate Bulletin Number 03-03-10-007E - Tire/Wheel Characteristics of GM Original Equipment Tires. - Equipment such as the Hunter GSP9700 MUST be calibrated prior to measuring tire/wheel assemblies for each vehicle. The purpose of this bulletin is to provide guidance to GM dealers when using tire force variation measurement equipment, such as the Hunter GSP9700. This type of equipment can be a valuable tool in diagnosing vehicle ride concerns. The most common ride concern involving tire radial force variation is highway speed shake on smooth roads. Tire related smooth road highway speed shake can be caused by three conditions: imbalance, out of round and tire force variation. These three conditions are not necessarily related. All three conditions must be addressed. Imbalance is normally addressed first, because it is the simpler of the three to correct. Off-vehicle, two plane dynamic wheel balancers are readily available and can accurately correct any imbalance. Balancer calibration and maintenance, proper attachment of the wheel to the balancer, and proper balance weights, are all factors required for a quality balance. However, a perfectly balanced tire/wheel assembly can still be "oval shaped" and cause a vibration. Before balancing, perform the following procedures. Tire and Wheel Diagnosis 1. Set the tire pressure to the placard values. 2. With the vehicle raised, ensure the wheels are centered on the hub by loosening all wheel nuts and hand-tightening all nuts first by hand while shaking the wheel, then torque to specifications using a torque wrench, NOT a torque stick. 3. Visually inspect the tires and the wheels. Inspect for evidence of the following conditions and correct as necessary: - Missing balance weights - Bent rim flange - Irregular tire wear - Incomplete bead seating - Tire irregularities (including pressure settings) - Mud/ice build-up in wheel - Stones in the tire tread - Remove any aftermarket wheels and/or tires and restore vehicle to original condition prior to diagnosing a smooth road shake condition. 4. Road test the vehicle using the Electronic Vibration Analyzer (EVA) essential tool. Drive for a sufficient distance on a known, smooth road surface to duplicate the condition. Determine if the vehicle is sensitive to brake apply. If the brakes are applied lightly and the pulsation felt in the steering wheel increases, refer to the Brakes section of the service manual that deals with brake-induced pulsation. If you can start to hear the vibration as a low boom noise (in addition to feeling it), but cannot see it, the vehicle likely has a first order (one pulse per propshaft revolution) driveline vibration. Driveline first order vibrations are high enough in frequency that most humans can start to hear them at highway speeds, but are too high to be able to be easily seen. These issues can be caused by driveline imbalance or misalignment. If the vehicle exhibits this low boom and the booming pulses in-and-out on a regular basis (like a throbbing), chances are good that the vehicle could have driveline vibration. This type Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Wheels: > 00-03-10-006F > May > 10 > Wheels/Tires - Tire Radial Force Variation (RFV) > Page 3343 of vibration is normally felt more in the "seat of the pants" than the steering wheel. 5. Next, record the Hertz (Hz) reading as displayed by the EVA onto the tire data worksheet found at the end of this bulletin. This should be done after a tire break-in period of at least 16 km (10 mi) at 72 km/h (45 mph) or greater, in order to eliminate any possible tire flat-spotting. This reading confirms what the vehicle vibration frequency is prior to vehicle service and documents the amount of improvement occurring as the result of the various steps taken to repair. Completing the Steering Wheel Shake Worksheet below is required. A copy of the completed worksheet must be saved with the R.O. and a copy included with any parts returned to the Warranty Parts Center for analysis. A reading of 35 to 50 Hz typically indicates a first order propshaft vibration. If this is the situation, refer to Corporate Bulletin Number 08-07-30-044D. Generally, a reading between 10 and 20 Hz indicates a tire/wheel vibration and if this is the reading obtained, continue using this bulletin. If the tire 1st order vibration goes away and stays away during this evaluation, the cause is likely tire flat-spotting. Tire flat-spotting vibration may come and go at any speed over 72 km/h (45 mph) during the first 10 minutes of operation, if vibration continues after 10 minutes of driving at speeds greater than 72 km/h (45 mph), tire flat-spotting can be ruled out as the cause for vibration. 6. If flat-spotting is the cause, provide the explanation that this has occurred due to the vehicle being parked for long periods of time and that the nature of the tire is to take a set. Refer to Corporate Bulletin Number 03-03-10-007E: Information on Tire/Wheel Characteristics (Vibration, Balance, Shake, Flat Spotting) of GM Original Equipment Tires. 7. If the road test indicates a shake/vibration exists, check the imbalance of each tire/wheel assembly on a known, calibrated, off-car dynamic balancer.Make sure the mounting surface of the wheel and the surface of the balancer are absolutely clean and free of debris. Be sure to chose the proper cone/collet for the wheel, and always use the pilot bore for centering. Never center the wheel using the hub-cap bore since it is not a precision machined surface. If any assembly calls for more than 1/4 ounce on either rim flange, remove all balance weights and rebalance to as close to zero as possible. If you can see the vibration (along with feeling it) in the steering wheel (driving straight without your hands on the wheel), it is very likely to be a tire/wheel first order (one pulse per revolution) disturbance. First order disturbances can be caused by imbalance as well as non-uniformities in tires, wheels or hubs. This first order frequency is too low for a human to hear, but if the amplitude is high enough, it can be seen. If a vibration or shake still exists after balancing, any out of round conditions, of the wheel, and force variation conditions of the tire, must be addressed. Equipment such as the Hunter GSP9700 can address both (it is also a wheel balancer). Tire radial force vibration (RFV) can be defined as the amount of stiffness variation the tire will produce in one revolution under a constant load. Radial force variation is what the vehicle feels because the load (weight) of the vehicle is always on the tires. Although free runout of tires (not under load) is not always a good indicator of a smooth ride, it is critical that total tire/wheel assembly runout be within specification. Equipment such as the Hunter GSP9700 loads the tire, similar to on the vehicle, and measures radial force variation of the tire/wheel assembly. Note that the wheel is affecting the tire's RFV measurement at this point. To isolate the wheel, its runout must be measured. This can be easily done on the Hunter, without the need to set up dial indicators. If the wheel meets the runout specification, the tire's RFV can then be addressed. After measuring the tire/wheel assembly under load, and the wheel alone, the machine then calculates (predicts) the radial force variation of the tire. However, because this is a prediction that can include mounting inaccuracies, and the load wheel is much smaller in diameter than used in tire production, this type of service equipment should NOT be used to audit new tires. Rather, it should be used as a service diagnostic tool to minimize radial force variation of the tire/wheel assembly. Equipment such as the Hunter GSP9700 does an excellent job of measuring wheel runout, and of finding the low point of the wheel (for runout) and the high point of the tire (for radial force variation). This allows the tire to be matched mounted to the wheel for lowest tire/wheel assembly force variation. The machine will simplify this process into easy steps. The following assembly radial force variation numbers should be used as a guide: When measuring RFV and match mounting tires perform the following steps. Measuring Wheel Runout and Assembly Radial Force Variation Important The completed worksheet at the end of this bulletin must be attached to the hard copy of the repair order. - Measure radial force variation and radial runout. - If a road force/balancing machine is used, record the radial force variation (RFV) on the worksheet at the end of this bulletin. It may be of benefit to have the lowest RFV assembly to the front left corner. If the machine is not available and the EVA data suggests there is an issue, swap the tire and wheel assemblies from the front to the back. Re-check on the EVA and if the problem still exists, test another vehicle to find tires that do not exhibit the same frequency and swap those tires onto the subject vehicle. - If a runout/balancing machine is used, record the radial runout of the tire/wheel assemblies on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies are more than.040 in (1.02 mm), match mount the tire to the wheel to get below.040 in (1.02 mm). For sensitive customers, readings of 0.030 inch (0.76 mm) or less are preferable, it may also be of benefit to have the lowest runout assembly to the front left corner. If the machine is not available and the EVA data suggests there is an issue, swap the tire and wheel assemblies from the front to the back. Re-check on the EVA and if the problem still exists, test another vehicle to find tires that do not exhibit the same frequency and swap those tires Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Wheels: > 00-03-10-006F > May > 10 > Wheels/Tires - Tire Radial Force Variation (RFV) > Page 3344 onto the subject vehicle. - After match mounting, the tire/wheel assembly must be rebalanced. If match mounting tires to in-spec wheels produces assembly values higher than these, tire replacement may be necessary. Replacing tires at lower values will probably mean good tires are being condemned. Because tires can sometimes become temporarily flat-spotted, which will affect force variation, it is important that the vehicle be driven at least 16 km (10 mi) prior to measuring. Tire pressure must also be adjusted to the usage pressure on the vehicle's tire placard prior to measuring. Most GM vehicles will tolerate radial force variation up to these levels. However, some vehicles are more sensitive, and may require lower levels. Also, there are other tire parameters that equipment such as the Hunter GSP9700 cannot measure that may be a factor. In such cases, TAC should be contacted for further instructions. Important - When mounting a GM wheel to a wheel balancer/force variation machine, always use the wheel's center pilot hole. This is the primary centering mechanism on all GM wheels; the bolt holes are secondary. Usually a back cone method to the machine should be used. For added accuracy and repeatability, a flange plate should be used to clamp the wheel onto the cone and machine. This system is offered by all balancer manufacturers in GM's dealer program. - Any type of service equipment that removes tread rubber by grinding, buffing or truing is NOT recommended, and may void the tire warranty. However, tires may have been ground by the tire company as part of their tire manufacturing process. This is a legitimate procedure.

Please discard Corporate Bulletin Number 08-03-10-006B (Section 03 - Suspension). Condition Some customers may comment on a tire that slowly loses air pressure over a period of days or weeks. Cause Abrasive elements in the environment may intrude between the tire and wheel at the bead seat. There is always some relative motion between the tire and wheel (when the vehicle is driven) and this motion may cause the abrasive particles to wear the wheel and tire materials. As the wear continues, there may also be intrusion at the tire/wheel interface by corrosive media from the environment. Eventually a path for air develops and a 'slow' leak may ensue. This corrosion may appear on the inboard or outboard bead seating surface of the wheel. This corrosion will not be visible until the tire is dismounted from the wheel. Notice This bulletin specifically addresses issues related to wheel bead seat corrosion that may result in an air leak. For issues related to porosity of the wheel casting that may result in an air leak, please refer to Corporate Bulletin Number 05-03-10-006F - Low Tire Pressure, Leaking Cast Aluminum Wheels (Repair with Adhesive Sealant) Correction In most cases, this type of air loss can be corrected by following the procedure below. Important DO NOT replace a wheel for slow air loss unless you have evaluated and/or tried to repair the wheel with the procedure below. Notice The repair is no longer advised or applicable for chromed aluminum wheels. 1. Remove the wheel and tire assembly for diagnosis. Refer to Tire and Wheel Removal and Installation in SI. 2. After a water dunk tank leak test, if you determine the source of the air leak to be around the bead seat of the wheel, dismount the tire to examine the bead seat. Shown below is a typical area of bead seat corrosion.Typical Location of Bead Seat Corrosion Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Wheels: > 08-03-10-006C > Apr > 10 > Tires/Wheels - Tire Slowly Goes Flat/Warning Light ON > Page 3355 Important Other forms of slow air leaks are possible. If the body of the tire, valve stem and wheel flange show no signs of air seepage, refer to Corporate Bulletin Number 05-03-10-003D for additional information on possible wheel porosity issues. 3. Bead seat corrosion is identified by what appears like blistering of the wheel finish, causing a rough or uneven surface that is difficult for the tire to maintain a proper seal on. Below is a close-up photo of bead seat corrosion on an aluminum wheel that was sufficient to cause slow air loss. Close-Up of Bead Seat Corrosion 4. If corrosion is found on the wheel bead seat, measure the affected area as shown below. - For vehicles with 32,186 km (20,000 mi) or less, the total allowable combined linear area of repairable corrosion is 100 mm (4 in) or less. If the total area(s) of corrosion exceed these dimensions, the wheel should be replaced. - For vehicles that have exceeded 32,186 km (20,000 mi), the total allowable combined linear area of repairable corrosion is 200 mm (8 in) or less. If the total area(s) of corrosion exceed these dimensions, the wheel should be replaced. 5. In order to correct the wheel leak, use a clean-up (fine cut) sanding disc or biscuit to remove the corrosion and any flaking paint. You should remove the corrosion back far enough until you reach material that is stable and firmly bonded to the wheel. Try to taper the edge of any flaking paint as best you can in order to avoid sharp edges that may increase the chance of a leak reoccurring. The photo below shows an acceptable repaired surface. Notice Corrosion that extends up the lip of the wheel, where after the clean-up process it would be visible with the tire mounted, is only acceptable on the inboard flange. The inboard flange is not visible with the wheel assembly in the mounted position. If any loose coatings or corrosion extend to the visible surfaces on the FACE of the wheel, that wheel must be replaced. Important Remove ONLY the material required to eliminate the corrosion from the bead seating surface. DO NOT remove excessive amounts of material. ALWAYS keep the sealing surface as smooth and level as possible.

Once the corrosion has been eliminated, you should coat the repaired area with a commercially available tire sealant such as Patch Brand Bead Sealant or equivalent. Commercially available bead sealants are black rubber-like coatings that will permanently fill and seal the resurfaced bead seat. At 21°C (70°F) ambient temperature, this sealant will set-up sufficiently for tire mounting in about 10 minutes.Coated and Sealed Bead Seat 7. Remount the tire and install the repaired wheel and tire assembly. Refer to Tire and Wheel Removal and Installation in SI.

Analysis of Returned Wheels Chrome wheels returned under the New Vehicle Limited Warranty for pitting concerns have recently been evaluated. This condition is usually most severe in the vent (or window) area of the front wheels. This "pitting" may actually be brake dust that has been allowed to accumulate on the wheel. The longer this accumulation builds up, the more difficult it is to remove. Cleaning the Wheels In all cases, the returned wheels could be cleaned to their original condition using GM Vehicle Care Cleaner Wax, P/N 12377966 (in Canada, P/N 10952905). When using this product, you should confine your treatment to the areas of the wheel that show evidence of the brake dust build-up. This product is only for use on chromed steel or chromed aluminum wheels.

Figure 1 Chemical staining in most cases results from acid based cleaners (refer to Figure 1 for an example). These stains are frequently milky, black, or greenish in appearance. They result from using cleaning solutions that contain acids on chrome wheels. Soap and water is usually sufficient to clean wheels. If the customer insists on using a wheel cleaner they should only use one that specifically states that it is safe for chromed wheels and does not contain anything in the following list. (Dealers should also survey any products they use during prep or normal cleaning of stock units for these chemicals.) - Ammonium Bifluoride (fluoride source for dissolution of chrome) - Hydrofluoric Acid (directly dissolves chrome) - Hydrochloric Acid (directly dissolves chrome) - Sodium Dodecylbenzenesulfonic Acid - Sulfamic Acid - Phosphoric Acid - Hydroxyacetic Acid Notice Many wheel cleaner instructions advise to take care to avoid contact with painted surfaces. Most customers think of painted surfaces as the fenders, quarter panels and other exterior sheet metal. Many vehicles have painted brake calipers. Acidic wheel cleaners may craze, crack, or discolor the paint on the brake calipers. Damage from wheel cleaners is not covered under the vehicle new car warranty. Soap and water applied with a soft brush is usually all that is required to clean the calipers. Whenever any wheel cleaner is used, it must be THOROUGHLY rinsed off of the wheel with clean, clear water. Special care must be taken to rinse under the hub cap, balance weights, wheel nuts, lug nut caps, between the wheel cladding and off the back side of the wheel. Wheels returned to the Warranty Parts Center (WPC) that exhibit damage from wheel cleaners most often have the damage around and under the wheel weight where the cleaner was incompletely flushed away. Notice Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Other Service Bulletins for Wheels: > 00-03-10-002F > Apr > 11 > Wheels - Chrome Wheel Staining/Pitting/Corrosion > Page 3367 Do not use cleaning solutions that contain hydrofluoric, oxalic and most other acids on chrome wheels (or any wheels). If the customer is unsure of the chemical make-up of a particular wheel cleaner, it should be avoided. For wheels showing signs of milky staining from acidic cleaners, refer to Customer Assistance and Instructions below. Warranty of Stained Chrome Wheels Stained wheels are not warrantable. Most acid based cleaners will permanently stain chrome wheels. Follow-up with dealers has confirmed that such cleaners were used on wheels that were returned to the Warranty Parts Center (WPC). Any stained wheels received by the WPC will be charged back to the dealership. To assist the customer, refer to Customer Assistance and Instructions below. Pitting or Spotted Appearance of Chrome Wheels Figure 2 A second type or staining or finish disturbance may result from road chemicals, such as calcium chloride used for dust control of unpaved roads. The staining will look like small pitting (refer to Figure 2). This staining will usually be on the leading edges of each wheel spoke, but may be uniformly distributed. If a vehicle must be operated under such conditions, the chrome wheels should be washed with mild soap and water and thoroughly rinsed as soon as conveniently possible. Important Road chemicals, such as calcium chloride used for dust control of unpaved roads, can also stain chrome wheels. The staining will look like small pitting. This staining will usually be on the leading edges of each wheel spoke. This is explained by the vehicle traveling in the forward direction while being splashed by the road chemical. If a vehicle must be operated under such conditions, the chrome wheels should be washed with mild soap and water and thoroughly rinsed as soon as conveniently possible. Warranty of Pitted or Spotted Chrome Wheels Wheels returned with pitting or spotting as a result of road chemicals may be replaced one time. Damage resulting from contact with these applied road chemicals is corrosive to the wheels finish and may cause damage if the wheels are not kept clean. Important Notify the customer that this is a one time replacement. Please stress to the customer the vital importance of keeping the wheels clean if they are operating the vehicle in an area that applies calcium chloride or other dust controlling chemicals! "GM of Canada" dealers require prior approval by the District Manager - Customer Care and Service Process (DM-CCSP). "Stardust" Corrosion of Chrome Wheels Figure 3 A third type of finish disturbance results from prolonged exposure to brake dust and resultant penetration of brake dust through the chrome. As brakes are applied hot particles of brake material are thrown off and tend to be forced through the leading edge of the wheel spoke windows by airflow. These Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Other Service Bulletins for Wheels: > 00-03-10-002F > Apr > 11 > Wheels - Chrome Wheel Staining/Pitting/Corrosion > Page 3368 hot particles embed themselves in the chrome layer and create a small pit. If the material is allowed to sit on the wheel while it is exposed to moisture or salt, it will corrode the wheel beneath the chrome leaving a pit or small blister in the chrome. Heavy brake dust build-up should be removed from wheels by using GM Chrome Cleaner and Polish, P/N 1050173 (in Canada use 10953013). For moderate cleaning, light brake dust build-up or water spots use GM Swirl Remover Polish, P/N 12377965 (in Canada, use Meguiars Plast-X(TM) Clear Plastic Cleaner and Polish #G12310C**). After cleaning, the wheel should be waxed using GM Cleaner Wax, P/N 12377966 (in Canada, use Meguiars Cleaner Wax #M0616C**), which will help protect the wheel from brake dust and reduce adhesion of any brake dust that gets on the wheel surface. For general maintenance cleaning, PEEK Metal Polish† may be used. It will clean and shine the chrome and leave behind a wax coating that may help protect the finish. Warranty of Stardust Corroded Chrome Wheels Wheels returned with pitting or spotting as a result of neglect and brake dust build-up may be replaced one time. Important Notify the customer that this is a one time replacement. Please stress to the customer the vital importance of keeping the wheels clean and free of prolonged exposure to brake dust build-up. "GM of Canada" dealers require prior approval by the District Manager - Customer Care and Service Process (DM-CCSP). Customer Assistance and Instructions GM has looked for ways customers may improve the appearance of wheels damaged by acidic cleaners. The following product and procedure has been found to dramatically improve the appearance of stained wheels. For wheels that have milky stains caused by acidic cleaners try the following: Notice THE 3M CHROME AND METAL POLISH REQUIRED FOR THIS PROCEDURE IS AN EXTREMELY AGGRESSIVE POLISH/CLEANER. THE WHEELS MUST BE CLEANED BEFORE APPLICATION TO AVOID SCRATCHING THE WHEEL SURFACE. THIS PRODUCT WILL REDUCE THE THICKNESS OF THE CHROME PLATING ON THE WHEEL AND IF USED INCORRECTLY OR EXCESSIVELY MAY REMOVE THE CHROME PLATING ALL TOGETHER, EXPOSING A LESS BRIGHT AND BRASSY COLORED SUB-LAYER. FOLLOW INSTRUCTIONS EXACTLY. 1. Wash the wheels with vigorously with soap and water. This step will clean and may reduce wheel staining. Flood all areas of the wheel with water to rinse. 2. Dry the wheels completely. Notice Begin with a small section of the wheel and with light pressure buff off polish and examine results. ONLY apply and rub with sufficient force and time to remove enough staining that you are satisfied with the results. Some wheels may be stained to the extent that you may only achieve a 50% improvement while others may be able to be restored to the original lustre. IN ALL CASES, only apply until the results are satisfactory. 3. Apply 3M Chrome and Metal Polish #39527* with a clean terry cloth towel. As you apply the polish, the staining will be diminished. 4. When dry, buff off the polish with a clean portion of the towel. 5. Repeat application of the 3M Chrome and Metal Polish until satisfied with the results. If continued applications fail to improve the appearance further discontinue use. This procedure will improve the appearance of the wheels and may, with repeated applications, restore the finish dramatically. For wheels that exhibit spotting from road chemicals the above procedure may marginally improve the condition but will not restore the finish or remove the pitting. In this type of staining the wheel finish has actually been removed in spots and no manner of cleaning will restore the finish. †*We believe this source and their products to be reliable.

Please discard Corporate Bulletin Number 99-08-51-007D (Section 08 - Body and Accessories). This bulletin updates General Motor's position on refinishing aluminum wheels. GM does not endorse any repairs that involve welding, bending, straightening or re-machining. Only cosmetic refinishing of the wheel's coatings, using recommended procedures, is allowed. Evaluating Damage In evaluating damage, it is the GM Dealer's responsibility to inspect the wheel for corrosion, scrapes, gouges, etc. The Dealer must insure that such damage is not deeper than what can be sanded or polished off. The wheel must be inspected for cracks. If cracks are found, discard the wheel. Any wheels with bent rim flanges must not be repaired or refinished. Wheels that have been refinished by an outside company must be returned to the same vehicle. The Dealer must record the wheel ID stamp or the cast date on the wheel in order to assure this requirement. Refer to Refinisher's Responsibility - Outside Company later in this bulletin. Aluminum Wheel Refinishing Recommendations - Chrome-plated aluminum wheels Re-plating these wheels is not recommended. - Polished aluminum wheels These wheels have a polyester or acrylic clearcoat on them. If the clearcoat is damaged, refinishing is possible. However, the required refinishing process cannot be performed in the dealer environment. Refer to Refinisher's Responsibility - Outside Company later in this bulletin. - Painted aluminum wheels These wheels are painted using a primer, color coat, and clearcoat procedure. If the paint is damaged, refinishing is possible. As with polished wheels, all original coatings must be removed first. Media blasting is recommended. Refer to GM Aluminum Refinishing Bulletin #53-17-03A for the re-painting of this type of wheel. - Bright, machined aluminum wheels These wheels have a polyester or acrylic clearcoat on them. In some cases, the recessed "pocket" areas of the wheel may be painted. Surface refinishing is possible. The wheel must be totally stripped by media blasting or other suitable means. The wheel should be resurfaced by using a sanding process rather than a machining process. This allows the least amount of material to be removed. Important Do not use any re-machining process that removes aluminum. This could affect the dimensions and function of the wheel. Painting is an option to re-clearcoating polished and bright machined aluminum wheels. Paint will better mask any surface imperfections and is somewhat more durable than clearcoat alone. GM recommends using Corsican SILVER WAEQ9283 for a fine "aluminum-like" look or Sparkle SILVER WA9967 for a very bright look. As an option, the body color may also be used. When using any of the painting options, it is recommended that all four wheels be refinished in order to maintain color uniformity. Refer to GM Aluminum Refinishing Bulletin #53-17-03A for specific procedures and product recommendations. Refinisher's Responsibility - Outside Company Important Some outside companies are offering wheel refinishing services. Such refinished wheels will be permanently marked by the refinisher and are warranted by the refinisher. Any process that re-machines or otherwise re-manufactures the wheel should not be used. A refinisher's responsibility includes inspecting for cracks using the Zyglo system or the equivalent. Any cracked wheels must not be refinished. No welding, hammering or reforming of any kind is allowed. The wheel ID must be recorded and follow the wheel throughout the process in order to assure that the same wheel is returned. A plastic media blast may be used for clean up of the wheel. Hand and/or lathe sanding of the machined surface and the wheel window is allowed. Material removal, though, must be kept to a minimum. Re-machining of the wheel is not allowed. Paint and/or clear coat must not be present on the following surfaces: the nut chamfers, the wheel mounting surfaces and the wheel pilot hole. The refinisher must permanently ID stamp the wheel and warrant the painted/clearcoated surfaces for a minimum of one year or the remainder of the new vehicle warranty, whichever is Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Other Service Bulletins for Wheels: > 99-08-51-007E > Mar > 11 > Wheels/Tires - Refinishing Aluminum Wheels > Page 3374 longer. Important Whenever a wheel is refinished, the mounting surface and the wheel nut contact surfaces must not be painted or clearcoated. Coating these surfaces could affect the wheel nut torque. When re-mounting a tire on an aluminum wheel, coated balance weights must be used in order to reduce the chance of future cosmetic damage.

This bulletin is intended to quickly review and reinforce simple but vital procedures to reduce the possibility of achieving low torque during wheel installation. Always refer to SI for wheel lug nut torque specifications and complete jacking instructions for safe wheel changing. Supercede: This bulletin is being revised to include the 2011 model year and update the available special tool list. Please discard Corporate Bulletin Number 06-03-10-010 (Section 03 Suspension). Frequency of Wheel Changes - Marketplace Driven Just a few years ago, the increasing longevity of tires along with greater resistance to punctures had greatly reduced the number of times wheels were removed to basically required tire rotation intervals. Today with the booming business in accessory wheels/special application tires (such as winter tires), consumers are having tire/wheel assemblies removed - replaced - or installed more than ever. With this increased activity, it opens up more of a chance for error on the part of the technician. This bulletin will review a few of the common concerns and mistakes to make yourself aware of. Proper Servicing Starts With the Right Tools The following tools have been made available to assist in proper wheel and tire removal and installation. - J 41013 Rotor Resurfacing Kit (or equivalent) - J 42450-A Wheel Hub Resurfacing Kit (or equivalent) Corroded Surfaces One area of concern is corrosion on the mating surfaces of the wheel to the hub on the vehicle. Excessive corrosion, dirt, rust or debris built up on these surfaces can mimic a properly tightened wheel in the service stall. Once the vehicle is driven, the debris may loosen, grind up or be washed away from water splash. This action may result in clearance at the mating surface of the wheel and an under-torqued condition. Caution Before installing a wheel, remove any buildup on the wheel mounting surface and brake drum or brake disc mounting surface. Installing wheels with poor metal-to-metal contact at the mounting surfaces can cause wheel nuts to loosen. This may cause a wheel to come off when the vehicle is moving, possibly resulting in a loss of control or personal injury. Whenever you remove the tire/wheel assemblies, you must inspect the mating surfaces. If corrosion is found, you should remove the debris with a die grinder equipped with a fine sanding pad, wire brush or cleaning disc. Just remove enough material to assure a clean, smooth mating surface. The J 41013 (or equivalent) can be used to clean the following surfaces: - The hub mounting surface - The brake rotor mounting surface - The wheel mounting surface Use the J 42450-A (or equivalent) to clean around the base of the studs and the hub. Lubricants, Grease and Fluids Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Other Service Bulletins for Wheels: > 06-03-10-010A > Jun > 10 > Wheels - Changing Procedures/Precautions > Page 3379 Some customers may use penetrating oils, grease or other lubricants on wheel studs to aid in removal or installation. Always use a suitable cleaner/solvent to remove these lubricants prior to installing the wheel and tire assemblies. Lubricants left on the wheel studs may cause improper readings of wheel nut torque. Always install wheels to clean, dry wheel studs ONLY. Notice Lubricants left on the wheel studs or vertical mounting surfaces between the wheel and the rotor or drum may cause the wheel to work itself loose after the vehicle is driven. Always install wheels to clean, dry wheel studs and surfaces ONLY. Beginning with 2011 model year vehicles, put a light coating of grease, GM P/N 1051344 (in Canada, P/N 9930370), on the inner surface of the wheel pilot hole to prevent wheel seizure to the axle or bearing hub. Wheel Stud and Lug Nut Damage Always inspect the wheel studs and lug nuts for signs of damage from crossthreading or abuse. You should never have to force wheel nuts down the stud. Lug nuts that are damaged may not retain properly, yet give the impression of fully tightening. Always inspect and replace any component suspected of damage. Tip Always start wheel nuts by hand! Be certain that all wheel nut threads have been engaged BEFORE tightening the nut. Important If the vehicle has directional tread tires, verify the directional arrow on the outboard side of the tire is pointing in the direction of forward rotation. Wheel Nut Tightening and Torque Improper wheel nut tightening can lead to brake pulsation and rotor damage. In order to avoid additional brake repairs, evenly tighten the wheel nuts to the proper torque specification as shown for each vehicle in SI. Always observe the proper wheel nut tightening sequence as shown below in order to avoid trapping the wheel on the wheel stud threads or clamping the wheel slightly off center resulting in vibration.

Please discard Corporate Bulletin Number 04-03-10-012A (Section 03 - Suspension). Analysis of Returned Wheels Chrome wheels returned under the New Vehicle Limited Warranty for pitting concerns have recently been evaluated. This condition is usually most severe in the vent (or window) area of the front wheels. This "pitting" may actually be brake dust that has been allowed to accumulate on the wheel. The longer this accumulation builds up, the more difficult it is to remove. Cleaning the Wheels In all cases, the returned wheels could be cleaned to their original condition using GM Vehicle Care Cleaner Wax, P/N 12377966 (in Canada, P/N 10952905). When using this product, you should confine your treatment to the areas of the wheel that show evidence of the brake dust build-up. This product is only for use on chromed steel or chromed aluminum wheels. Parts Information Warranty Information Wheel replacement for this condition is NOT applicable under the terms of the New Vehicle Limited Warranty.

Four Wheel Drive and All Wheel Drive Light Duty Trucks Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Towing Information > System Information > Technical Service Bulletins > Vehicle - Recreational (Dinghy) Towing Information > Page 3422 Dinghy towing is permitted on the trucks shown with the transfer case placed in the Neutral position. Refer to the end of this bulletin for identification information to determine type of transfer case. The vehicles shown should NOT be dinghy towed because the transfer cases in these vehicles either have no neutral position or do not have an internal oil pump to provide lubrication while being towed. In order to properly tow the vehicles, place the vehicle on a platform trailer with all four tires off the ground. Avoid towing the vehicle with all four tires on the ground. In rare instances when towing with all four tires on the ground is unavoidable, both the front and the rear propeller shafts must be removed in order to prevent damage to the transfer case and/or transmission. Because front and rear propeller shafts are matched to attaching components at assembly, refer to the applicable Service Manual for procedures on propeller shaft removal/installation. Towing Procedure In order to properly dinghy tow the vehicle, use the following procedure: 1. Firmly set the parking brake. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Maintenance > Towing Information > System Information > Technical Service Bulletins > Vehicle - Recreational (Dinghy) Towing Information > Page 3423 2. Place the AT in Park (P) or the MT in the lowest gear (1st). 3. Securely attach the vehicle being towed to the tow vehicle. Caution: Shifting the transfer case to Neutral can cause the vehicle to roll, even if the transmission is in park (automatic) or 1st gear (manual), and may cause personal injury. 4. If equipped, place the transfer case shift lever in Neutral (N). Note: Use extra care whenever towing another vehicle. Do not exceed the towing vehicle's gross combination weight (GCW) by adding the weight of the dinghy towed vehicle or vehicle damage may result. 5. When the vehicle being towed is firmly attached to the tow vehicle, release the parking brake. 6. The Owner's Manual specifies the appropriate ignition key position to ensure that the steering is unlocked to allow the front wheels to follow the tow vehicle. Rear Wheel Drive Light Duty Trucks Important: ^ Dust or dirt can enter the back of the transmission through the opening created by the removal of the slip yoke from the transmission if proper protection is not provided. ^ Verify that the transmission fluid is at the proper level before driving the truck. Rear wheel drive vehicles, equipped with AT or MT, should NOT be dinghy towed. These transmissions have no provisions for internal lubrication while being towed. In order to properly tow these vehicles, place the vehicle on a platform trailer with all four tires off the ground. Avoid towing the vehicle with all four tires on the ground. In rare instances when it is unavoidable that a rear wheel drive vehicle be dinghy towed, the propeller shaft to axle yoke orientation should be marked and the propeller shaft removed. Refer to the applicable Service Manual for procedures on propeller shaft removal/installation.

Important: Remove the Powertrain Control Module (PCM) and the ignition fuses from the I/P fuse block. 1. Disable the ignition. 2. Disable the fuel systems. 3. Remove the spark plugs from all the cylinders. 4. Remove the air duct from the throttle body. 5. Block the throttle plate in the open position. 6. Measure the engine compression, using the following procedure: 1. Firmly install the compression gauge to the spark plug hole. 2. Have an assistant crank the engine through at least 4 compression strokes in the testing cylinder. 3. Record the readings on the gauge at each stroke. 4. Disconnect the gauge. 5. Repeat the compression test for each cylinder. 7. Record the compression readings from all of the cylinders. * The lowest reading should not be less than 70 percent of the highest reading. * No cylinder reading should be less than 689 kPa (100 psi). 8. The following list contains examples of the possible measurements: * When the compression measurement is normal, the compression builds up quickly and evenly to the specified compression on each cylinder. * When the compression is low on the first stroke and tends to build up on the following strokes, but does not reach the normal compression, the piston rings may be the cause. * If the compression improves considerably with the addition of three squirts of oil, the piston rings may be the cause. * When the compression is low on the first stroke and does not build up in the following strokes, the valves may be the cause. * The addition of oil does not affect the compression, the valves may be the cause. * When the compression is low on two adjacent cylinders, or coolant is present in the crankcase, the head gasket may be the cause. 9. Remove the block from the throttle plate. 10. Install the air duct to the throttle body. 11. Install the spark plugs. 12. Install the Powertrain Control Module (PCM) fuse. 13.

Please discard Corporate Bulletin Number 08-06-01-008 (Section 06 - Engine). Background Several aftermarket companies offer laser alignment tools for accessory drive systems that can be very helpful in eliminating drive belt noise as a result of misaligned pulleys. Typically pricing ranges from $160 - $200. EN-49228 Laser Alignment Tool - Drive Belt The GM Tool program has now made available a competitive, simple to use and time-saving laser tool to assist in achieving precise alignment of the drive belt pulleys. This optional tool removes the guesswork from proper pulley alignment and may serve to reduce comebacks from: - Drive Belt Noise - Accelerated Drive Belt Wear - Drive Belt Slippage Instructions The instructions below are specific only to the truck Gen IV V-8 family of engines. These instructions are only for illustrative purposes to show how the tool may be used. Universal instructions are included in the box with the Laser Alignment Tool - Drive Belt. Caution - Do not look directly into the beam projected from the laser. - Use caution when shining the laser on highly polished or reflective surfaces. Laser safety glasses help reduce laser beam glare in many circumstances. - Always use laser safety glasses when using the laser. Laser safety glasses are not designed to protect eyes from direct laser exposure. 1. Observe and mark the serpentine belt orientation.

Remove the serpentine belt from the accessory drive system. 3. Install the tool onto the power steering pulley. Position the legs of the tool into the outer grooves of the pulley, farthest from the front of the engine. 4. Install the retaining cord around the pulley and to the legs of the tool. 5. Put on the laser safety glasses provided with the tool. 6. Depress the switch on the rear of the tool to activate the light beam. 7. Rotate the power steering pulley as required to project the light beam onto the crankshaft balancer pulley grooves. 8. Inspect for proper power steering pulley alignment. - If the laser beam projects onto the second rib or raised area (1), the pulleys are aligned properly. - If the laser beam projects more than one-quarter rib 0.9 mm (0.035 in) mis-alignment, adjust the position of the power steering pulley as required. - Refer to SI for Power Steering Pulley Removal and Installation procedures. 9. Install the serpentine belt to the accessory drive system in the original orientation. 10. Operate the vehicle and verify that the belt noise concern is no longer present.

Belt dressing causes the breakdown of the composition of the drive belt. Failure to follow this recommendation will damage the drive belt. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Technical Service Bulletins > Page 3559 Drive Belt: Description and Operation Drive Belt System Description The drive belt system consists of the following components: * The drive belt * The drive belt tensioner * The drive belt idler pulley * The crankshaft balancer pulley * The accessory drive component mounting brackets * The accessory drive components - The power steering pump, if belt driven - The generator - The A/C compressor, if equipped - The engine cooling fan, if belt driven - The water pump, if belt driven - The vacuum pump, if equipped - The air compressor, if equipped The drive belt system may use one belt or two belts. The drive belt is thin so that it can bend backwards and has several ribs to match the grooves in the pulleys. There also may be a V-belt style belt used to drive certain accessory drive components. The drive belts are made of different types of rubbers (chloroprene or EPDM) and have different layers or plys containing either fiber cloth or cords for reinforcement. Both sides of the drive belt may be used to drive the different accessory drive components. When the back side of the drive belt is used to drive a pulley, the pulley is smooth. The drive belt is pulled by the crankshaft balancer pulley across the accessory drive component pulleys. The spring loaded drive belt tensioner keeps constant tension on the drive belt to prevent the drive belt from slipping. The drive belt tensioner arm will move when loads are applied to the drive belt by the accessory drive components and the crankshaft. The drive belt system may have an idler pulley, which is used to add wrap to the adjacent pulleys. Some systems use an idler pulley in place of an accessory drive component when the vehicle is not equipped with the accessory.

It may be necessary to spray a small amount of water on the drive belts in order to duplicate the customers concern. If spraying water on the drive belt duplicates the symptom, cleaning the belt pulleys may be the probable solution. * If the noise is intermittent, verify the accessory drive components by varying their loads making sure they are operated to their maximum capacity. An overcharged A/C system, power steering system with a pinched hose or wrong fluid, or a generator failing are suggested items to inspect. * A chirping, squeal or whine noise may be caused by a loose or improper installation of a body or suspension component. Other items of the vehicle may also cause the noise. * The drive belts will not cause a whine noise. Test Description The numbers below refer to the step numbers on the diagnostic table. 2. The noise may not be engine related. This step is to verify that the engine is making the noise. If the engine is not making the noise do not proceed further with this table. 3. The noise may be an internal engine noise. Removing the drive belts one at a time and operating the engine for a brief period will verify the noise is related to the drive belt. When removing the drive belt the water pump may not be operating and the engine may overheat. Also DTCs may set when the engine is operating with the drive belts removed. 4. Inspect all drive belt pulleys for pilling. Pilling is the small balls or pills or it can be strings in the drive belt grooves from the accumulation of rubber dust. 6. Misalignment of the pulleys may be caused from improper mounting of the accessory drive component, incorrect installation of the accessory drive component pulley, or the pulley bent inward or outward from a previous repair. Test for a misaligned pulley using a straight edge in the pulley grooves across two or three pulleys. If a misaligned pulley is found refer to that accessory drive component for the proper installation procedure for that pulley. 10. Inspecting of the fasteners can eliminate the possibility that a wrong bolt, nut, spacer, or washer was installed. 12. Inspecting the pulleys for being bent should include inspecting for a dent or other damage to the pulleys that would prevent the drive belt from not seating properly in all of the pulley grooves or on the smooth surface of a pulley when the back side of the belt is used to drive the pulley. 14. This test is to verify that the drive belt tensioner operates properly. If the drive belt tensioner is not operating properly, proper belt tension may not be achieved to keep the drive belt from slipping which could cause a squeal noise. 15. This test is to verify that the drive belt is not too long, which would prevent the drive belt tensioner from working properly. Also if an incorrect length drive belt was installed, it may not be routed properly and may be turning an accessory drive component in the wrong direction. 16. Misalignment of the pulleys may be caused from improper mounting of the accessory drive component, incorrect installation of the accessory drive component pulley, or the pulley bent inward or outward from a previous repair. Test for a misaligned pulley using a straight edge in the pulley grooves across two or three pulleys. If a misaligned pulley is found refer to that accessory drive component for the proper installation procedure for that pulley. 17. This test is to verify that the pulleys are the correct diameter or width. Using a known good vehicle compare the pulley sizes. 19. Replacing the drive belt when it is not damaged or there is not excessive pilling will only be a temporary repair.

An extra load that is quickly applied on released by an accessory drive component may cause the drive belt to fall off the pulleys. Verify the accessory drive components operate properly. If the drive belt is the incorrect length, the drive belt tensioner may not keep the proper tension on the drive belt. Excessive wear on a drive belt is usually caused by an incorrect installation or the wrong drive belt for the application. Minor misalignment of the drive belt pulleys will not cause excessive wear, but will probably cause the drive belt to make a noise or to fall off. Excessive misalignment of the drive belt pulleys will cause excessive wear but may also make the drive belt fall off. Test Description The numbers below refer to the step numbers on the diagnostic table. 2. This inspection is to verify the condition of the drive belt. Damage may of occurred to the drive belt when the drive belt fell off. The drive belt may of been damaged, which caused the drive belt to fall off. Inspect the belt for cuts, tears, sections of ribs missing, or damaged belt plys. 4. Misalignment of the pulleys may be caused from improper mounting of the accessory drive component, incorrect installation of the accessory drive component pulley, or the pulley bent inward or outward from a previous repair. Test for a misaligned pulley using a straight edge in the pulley grooves across two or three pulleys. If a misaligned pulley is found refer to that accessory drive component for the proper installation procedure of that pulley. 5. Inspecting the pulleys for being bent should include inspecting for a dent or other damage to the pulleys that would prevent the drive belt from not seating properly in all of the pulley grooves or on the smooth surface of a pulley when the back side of the belt is used to drive the pulley. 6. Accessory drive component brackets that are bent or cracked will let the drive belt fall off. 7. Inspection of the fasteners can eliminate the possibility that a wrong bolt, nut , spacer, or washer was installed. Missing, loose, or the wrong fasteners may cause pulley misalignment from the bracket moving under load. Over tightening of the fasteners may cause misalignment of the accessory component bracket. 13. The inspection is to verify the drive belt is correctly installed on all of the drive belt pulleys. Wear on the drive belt may be caused by mis-positioning the drive belt by one groove on a pulley. 14. The installation of a drive belt that is too wide or too narrow will cause wear on the drive belt. The drive belt ribs should match all of the grooves on all of the pulleys. 15. This inspection is to verify the drive belt is not contacting any parts of the engine or body while the engine is operating. There should be sufficient clearance when the drive belt accessory drive components load varies. The drive belt should not come in contact with an engine or a body component when snapping the throttle.

Vibration from the engine operating may cause a body component or another part of the vehicle to make rumbling noise. Vibration can be caused by, but not limited to the air conditioning (A/C) system over charged, the power steering system restricted or the incorrect fluid, or an extra load on the generator. To help identify an intermittent or an improper condition, vary the loads on the accessory drive components. The drive belt may have a rumbling condition that can not be seen or felt. Sometimes replacing the drive belt may be the only repair for the symptom. If replacing the drive belt, completing the diagnostic table, and the noise is only heard when the drive belts are installed, there might be an accessory drive component with a failure. Varying the load on the different accessory drive components may aid in identifying which component is causing the rumbling noise. Test Description The numbers below refer to the step numbers on the diagnostic table. 2. This test is to verify that the symptom is present during diagnosing. Other vehicle components may cause a similar symptom. 3. This test is to verify that one of the drive belts is causing the rumbling noise or vibration. Rumbling noise may be confused with an internal engine noise due to the similarity in the description. Remove only one drive belt at a time if the vehicle has multiple drive belts. When removing the drive belts the water pump may not be operating and the engine may overheat. Also DTCs may set when the engine is operating with the drive belts removed. 4. Inspecting the drive belts is to ensure that they are not causing the noise. Small cracks across the ribs of the drive belt will not cause the noise. Belt separation is identified by the plys of the belt separating and may be seen at the edge of the belt our felt as a lump in the belt. 5. Small amounts of pilling is normal condition and acceptable. When the pilling is severe the drive belt does not have a smooth surface for proper operation. 9. Inspecting of the fasteners can eliminate the possibility that the wrong bolt, nut, spacer, or washer was installed. 11. This step should only be performed if the water pump is driven by the drive belt. Inspect the water pump shaft for being bent. Also inspect the water pump bearings for smooth operation and excessive play. Compare the water pump with a known good water pump. 12. Accessory drive component brackets that are bent, cracked, or loose may put extra strain on that accessory component causing it to vibrate.

Only those oils displaying the dexos‹›(TM) trademark and icon on the front label meet the demanding performance requirements and stringent quality standards set forth in the dexos‹›(TM) specification. Look on the front label for any of the logos shown above to identify an authorized, licensed dexos 1(TM) engine oil. GM dexos 1(TM) Engine Oil Specification Important General Motors dexos 1(TM) engine oil specification replaces the previous General Motors specifications GM6094M, GM4718M and GM-LL-A-025 for most GM gasoline engines. The oil specified for use in GM passenger cars and trucks, PRIOR to the 2011 model year remains acceptable for those previous vehicles. However, dexos 1(TM) is backward compatible and can be used in those older vehicles. In North America, starting with the 2011 model year, GM introduced dexos 1(TM) certified engine oil as a factory fill and service fill for gasoline engines. The reasons for the new engine oil specification are as follows: - To meet environmental goals such as increasing fuel efficiency and reducing engine emissions. - To promote long engine life. - To minimize the number of engine oil changes in order to help meet the goal of lessening the industry's overall dependence on crude oil. dexos 1(TM) is a GM-developed engine oil specification that has been designed to provide the following benefits: - Further improve fuel economy, to meet future corporate average fuel economy (CAFE) requirements and fuel economy retention by allowing the oil to maintain its fuel economy benefits throughout the life of the oil. - More robust formulations for added engine protection and aeration performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Engine Oil > Component Information > Technical Service Bulletins > Engine - GM dexos 1 and dexos 2(R) Oil Specifications > Page 3634 - Support the GM Oil Life System, thereby minimizing the replacement of engine oil, before its life has been depleted. - Reduce the duplication of requirements for a large number of internal GM engine oil specifications. International Lubricants Standardization and Approval Committee (ILSAC) GF-5 Standard In addition to GM dexos 1(TM), a new International Lubricants Standardization and Approval Committee (ILSAC) standard called GF-5, was introduced in October 2010. - There will be a corresponding API category, called: SN Resource Conserving. The current GF-4 standard was put in place in 2004 and will become obsolete in October 2011. Similar to dexos 1(TM), the GF-5 standard will use a new fuel economy test, Sequence VID, which demands a statistically significant increase in fuel economy versus the Sequence VIB test that was used for GF-4. - It is expected that all dexos 1(TM) approved oils will be capable of meeting the GF-5 standard. However, not all GF-5 engine oils will be capable of meeting the dexos 1(TM) specification. - Like dexos(TM), the new ILSAC GF-5 standard will call for more sophisticated additives. The API will begin licensing marketers during October 2010, to produce and distribute GF-5 certified products, which are expected to include SAE 0W-20, 0W-30, 5W-20, 5W-30 and 10W-30 oils. Corporate Average Fuel Economy (CAFE) Requirements Effect on Fuel Economy Since CAFE standards were first introduced in 1974, the fuel economy of cars has more than doubled, while the fuel economy of light trucks has increased by more than 50 percent. Proposed CAFE standards call for a continuation of increased fuel economy in new cars and trucks. To meet these future requirements, all aspects of vehicle operation are being looked at more critically than ever before. New technology being introduced in GM vehicles designed to increase vehicle efficiency and fuel economy include direct injection, cam phasing, turbocharging and active fuel management (AFM). The demands of these new technologies on engine oil also are taken into consideration when determining new oil specifications. AFM for example can help to achieve improved fuel economy. However alternately deactivating and activating the cylinders by not allowing the intake and exhaust valves to open contributes to additional stress on the engine oil. Another industry trend for meeting tough fuel economy mandates has been a shift toward lower viscosity oils. dexos 1(TM) will eventually be offered in several viscosity grades in accordance with engine needs: SAE 0W-20, 5W-20, 0W-30 and 5W-30. Using the right viscosity grade oil is critical for proper engine performance. Always refer to the Maintenance section of a vehicle Owner Manual for the proper viscosity grade for the engine being serviced. GM Oil Life System in Conjunction With dexos (TM) Supports Extended Oil Change Intervals To help conserve oil while maintaining engine protection, many GM vehicles are equipped with the GM Oil Life System. This system can provide oil change intervals that exceed the traditional 3,000 mile (4,830 km) recommendation. The dexos (TM) specification, with its requirements for improved oil robustness, compliments the GM Oil Life System by supporting extended oil change intervals over the lifetime of a vehicle. If all GM customers with GM Oil Life System equipped vehicles would use the system as intended, GM estimates that more than 100 million gallons of oil could be saved annually.

Look on the front label for any of the logos shown above to identify an authorized, licensed dexos 2(TM) engine oil. GM dexos 2(TM) Engine Oil Specification - dexos 2(TM) is approved and recommended by GM for use in Europe starting in model year 2010 vehicles, regardless of where the vehicle was manufactured. - dexos 2(TM) is the recommended service fill oil for European gasoline engines. Important The Duramax(TM) diesel engine is the exception and requires lubricants meeting specification CJ-4. - dexos 2(TM) is the recommended service fill oil for European light-duty diesel engines and replaces GM-LL-B-025 and GM-LL-A-025. - dexos 2(TM) protects diesel engines from harmful soot deposits and is designed with limits on certain chemical components to prolong catalyst life and protect expensive emission reduction systems. It is a robust oil, resisting degradation between oil changes and maintaining optimum performance longer.

These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). You should look for this information on the oil container, and use only those oils that are identified as meeting GM Standard GM6094M and have the starburst symbol on the front of the oil container. NOTICE: Use only engine oil identified as meeting GM Standard GM6094M and showing the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty. GM Goodwrench oil meets all the requirements for your vehicle. If you are in an area of extreme cold, where the temperature falls below -20°F (-29°C), it is recommended that you use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures. ENGINE OIL ADDITIVES Do not add anything to your oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you will need for good performance and engine protection.

Please discard Corporate Bulletin Number 07-06-01-016A (Section 06 - Engine/Propulsion System). Important Engine damage that is the result of an incorrect or improperly installed engine oil filter is not a warrantable claim. The best way to avoid oil filter quality concerns is to purchase ACDelco(R) oil filters directly from GMSPO. Oil filter misapplication may cause abnormal engine noise or internal damage. Always utilize the most recent parts information to ensure the correct part number filter is installed when replacing oil filters. Do not rely on physical dimensions alone. Counterfeit copies of name brand parts have been discovered in some aftermarket parts systems. Always ensure the parts you install are from a trusted source. Improper oil filter installation may result in catastrophic engine damage.

Please discard Corporate Bulletin Number 00-06-01-026B (Section 06 - Engine). When replacing an engine due to internal damage, extreme care should be taken when transferring the intake manifold to the new Goodwrench service engine long block. Internal damage may result in the potential discharge of internal engine component debris in the intake manifold via broken pistons and/or bent, broken, or missing intake valves. After removing the intake manifold from the engine, the technician should carefully inspect all of the cylinder head intake ports to see if the valve heads are still present and not bent. Usually when the valve heads are missing or sufficiently bent, internal engine component debris will be present to varying degrees in the intake port of the cylinder head. If this debris is present in any of the cylinder head intake ports, the intake manifold should be replaced. This replacement is required due to the complex inlet runner and plenum configuration of most of the intake manifolds, making thorough and complete component cleaning difficult and nearly impossible to verify complete removal of debris. Re-installation of an intake manifold removed from an engine with deposits of internal engine component debris may result in the ingestion of any remaining debris into the new Goodwrench service engine. This may cause damage or potential failure of the new service engine.

Ensure that the mandrel is snug to the crankshaft hub. Refer to the above illustration. Different types (styles) of rear main seals were used in production in different model years, engines and manufacturing facilities. As a result, the NEW style rear main seal that you will be installing may have a different appearance or shape than the one removed. Regardless of what type of seal was removed and what side was facing outside the engine, the new seal must be installed as described. Upon close inspection of the outer lip on the new seal, the words this side out" will be seen. This side of the seal must be facing OUTSIDE the engine when correctly installed. While this may seem backwards, it is correct. In addition, the protective nylon (plastic) sleeve that the seal is mounted on in the package was designed so that the seal can only be installed in the proper direction when using the installation tool described in the following steps. Install the rear main seal (1), with the protective nylon sleeve attached (2), onto the mandrel. The seal, if properly installed, will center on a step that protrudes from the center of the mandrel. As an error proof, seal will fit only one way onto the mandrel. Refer to the above illustration.

Clean the crankshaft sealing surface with a clean, lint free towel. Inspect the lead-in edge of the crankshaft for burrs or sharp edges that could damage the rear main oil seal. Remove any burrs or sharp edges with crocus cloth or equivalent before proceeding. Installation Procedure Do not remove the protective nylon sleeve from the new rear main seal prior to installation. The EN-48108 is designed to install the rear main seal with the protective sleeve in place. Never apply or use any oil, lubricants or sealing compounds on the crankshaft rear main oil seal. Align the mandrel dowel pin (EN-48108) to the dowel pin hole in the crankshaft. Refer to the above illustration. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Crankshaft Main Bearing Seal > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Crankshaft Main Bearing Seal: > 05-06-01-019F > Oct > 07 > Engine - Oil Leaks from Crankshaft Rear Main Seal > Page 3712 Using a large flat-bladed screwdriver, tighten the two mandrel screws to the crankshaft. Ensure that the mandrel is snug to the crankshaft hub. Refer to the above illustration. Different types (styles) of rear main seals were used in production in different model years, engines and manufacturing facilities. As a result, the NEW style rear main seal that you will be installing may have a different appearance or shape than the one removed. Regardless of what type of seal was removed and what side was facing outside the engine, the new seal must be installed as described. Upon close inspection of the outer lip on the new seal, the words this side out" will be seen. This side of the seal must be facing OUTSIDE the engine when correctly installed. While this may seem backwards, it is correct. In addition, the protective nylon (plastic) sleeve that the seal is mounted on in the package was designed so that the seal can only be installed in the proper direction when using the installation tool described in the following steps. Install the rear main seal (1), with the protective nylon sleeve attached (2), onto the mandrel. The seal, if properly installed, will center on a step that protrudes from the center of the mandrel. As an error proof, seal will fit only one way onto the mandrel. Refer to the above illustration. Before installing the outer drive drum, bearing, washer and the drive nut onto the threaded shaft, apply a small amount of the Extreme Pressure Lubricant J 23444-A, provided in the tool kit.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. CIRCUIT/SYSTEM DESCRIPTION The control module enables the fuel pump relay when the ignition switch is turned ON. The control module will disable the fuel pump relay within 2 seconds unless the control module detects ignition reference pulses. The control module continues to enable the fuel pump relay as long as ignition reference pulses are detected. The control module disables the fuel pump relay within 2 seconds if ignition reference pulses cease to be detected and the ignition remains ON.The fuel system is a returnless on-demand design. The fuel pressure regulator is a part of the primary fuel tank module, eliminating the need for a return pipe from the engine. A returnless fuel system reduces the internal temperature of the fuel tank by not returning hot fuel from the engine to the fuel tank. Reducing the internal temperature of the fuel tank results in lower evaporative emissions. An electric turbine style fuel pump attaches to the primary fuel tank module inside the fuel tank. The fuel pump supplies high pressure fuel through the fuel filter, past the fuel pressure regulator, and through the fuel feed pipe to the fuel injection system. The fuel pressure regulator has a T-joint that diverts the needed fuel to the fuel rail with the unused fuel dropping back into the reservoir of the primary fuel tank module. The primary fuel tank module contains a reverse flow check valve. The check valve and the fuel pressure regulator maintain fuel pressure in the fuel feed pipe and the fuel rail in order to prevent long cranking times. The primary fuel tank module also contains a primary jet pump and a secondary jet pump. Fuel pump flow loss, caused by vapor expulsion in the pump inlet chamber, is diverted to the primary jet pump and the secondary jet pump through a restrictive orifice located on the pump cover. The primary jet pump fills the reservoir of the primary fuel tank module. The secondary jet pump creates a venturi action which causes the fuel to be drawn from the secondary side of the fuel tank, through the fuel transfer pipe, to the primary side of the fuel tank. CIRCUIT/SYSTEM VERIFICATION IMPORTANT: Inspect the fuel system for damage or external leaks before proceeding. - Verify that adequate fuel is in the fuel tank before proceeding. - The fuel pump relay may need to be commanded ON a few times in order to obtain the highest possible fuel pressure. - Before proceeding with this test review the User Manual CH 48027-5 for Safety Information and Instructions. 1. Ignition ON, engine OFF, command the fuel pump relay ON with a scan tool. You should hear the fuel pump turn ON and OFF. - If the fuel pump does not operate, refer to Fuel Pump Electrical Circuit Diagnosis. See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Component Tests and General Diagnostics 2. Ignition OFF, all accessories OFF, install a CH-48027. 3. Ignition ON, engine OFF, command the fuel pump relay ON with a scan tool. Verify the fuel pressure is between 384-425 kPa (56-62 psi) and does not decrease more than 34 kPa (5 psi) in 1 minute. CIRCUIT/SYSTEM TESTING 1. IMPORTANT: - The fuel pump relay may need to be commanded ON a few times in order to obtain the highest possible fuel pressure. - DO NOT start the engine. Ignition ON, engine OFF, command the fuel pump relay ON with a scan tool and observe the fuel pressure gage while the fuel pump is operating. Verify the fuel pressure is between 384-425 kPa (56-62 psi). If the fuel pressure is greater than the specified range, replace the fuel pump module. - If the fuel pressure is less than the specified range, test, inspect, and repair the items listed below. If all items test normal, replace the fuel pump module. - Restricted fuel feed pipe - Restricted or plugged strainer - Inspect the harness connectors and the ground circuits of the fuel pump for poor connections. 2. Verify that the fuel pressure does not decrease more than 34 kPa (5 psi) in 1 minute. 1. If the fuel pressure decreases more than the specified value, perform the following procedure: 2. Ignition OFF, relieve the fuel pressure. Refer to Fuel Pressure Relief. See: Fuel Filter/Fuel Pressure Release/Service and Repair 3. Install the J 37287 between the fuel feed pipe and the fuel rail. 4. Open the valve on the J 37287. 5. Ignition ON, command the fuel pump relay ON with a scan tool and bleed the air from the CH-48027. 6. Command the fuel pump relay ON and then OFF with a scan tool. 7. Close the valve on the J 37287. 8. Monitor the fuel pressure for 1 minute.

An incorrect spark plug causes driveability conditions. Refer to Ignition System Specifications for the correct spark plug. - Ensure that the spark plug has the correct heat range. An incorrect heat range causes the following conditions: Spark plug fouling-Colder plug - Pre-ignition causing spark plug and/or engine damage-Hotter plug SPARK PLUG INSPECTION - Inspect the terminal post (1) for damage. Inspect for a bent or broken terminal post (1). - Test for a loose terminal post (1) by twisting and pulling the post. The terminal post (1) should NOT move. - Inspect the insulator (2) for flashover or carbon tracking, soot. This is caused by the electrical charge traveling across the insulator (2) between the terminal post (1) and ground. Inspect for the following conditions: Inspect the spark plug boot for damage. - Inspect the spark plug recess area of the cylinder head for moisture, such as oil, coolant, or water. A spark plug boot that is saturated causes arcing to ground. - Inspect the insulator (2) for cracks. All or part of the electrical charge may arc through the crack instead of the electrodes (3, 4). Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Technical Service Bulletins > Page 3836 - Inspect for evidence of improper arcing. Measure the gap between the center electrode (4) and the side electrode (3) terminals. An excessively wide electrode gap can prevent correct spark plug operation. - Inspect for the correct spark plug torque. Insufficient torque can prevent correct spark plug operation. An over torqued spark plug, causes the insulator (2) to crack. - Inspect for signs of tracking that occurred near the insulator tip instead of the center electrode (4). - Inspect for a broken or worn side electrode (3). - Inspect for a broken, worn, or loose center electrode (4) by shaking the spark plug. A rattling sound indicates internal damage. - A loose center electrode (4) reduces the spark intensity. - Inspect for bridged electrodes (3, 4). Deposits on the electrodes (3, 4) reduce or eliminates the gap. - Inspect for worn or missing platinum pads on the electrodes (3, 4), if equipped. - Inspect for excessive fouling. - Inspect the spark plug recess area of the cylinder head for debris. Dirty or damaged threads can cause the spark plug not to seat correctly during installation. SPARK PLUG VISUAL INSPECTION - Normal operation-Brown to grayish-tan with small amounts of white powdery deposits are normal combustion by-products from fuels with additives. - Carbon fouled-Dry, fluffy, black carbon or soot caused by the following conditions: Rich fuel mixtures Leaking fuel injectors - Excessive fuel pressure - Restricted air filter element - Incorrect combustion - Reduced ignition system voltage output Weak coils - Worn ignition wires - Incorrect spark plug gap - Excessive idling or slow speeds under light loads can keep spark plug temperatures so low that normal combustion deposits may not burn off. - Deposit fouling-Oil, coolant, or additives that include substances such as silicone, very white coating, reduces the spark intensity. Most powdery deposits will not effect spark intensity unless they form into a glazing over the electrode.

Attempting to remove spark plugs from a hot engine can cause the spark plugs to seize. This can damage the cylinder head threads. - Clean the spark plug recess area before removing the spark plug. Failure to do so can result in engine damage due to dirt or foreign material entering the cylinder head, or in contamination of the cylinder head threads. Contaminated threads may prevent proper seating of the new spark plug. - Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine. 1. Remove the spark plug wires from the spark plugs. 2. Remove the spark plugs (1) from the cylinder head. INSTALLATION PROCEDURE 1. NOTE: It is important to check the gap of all new and reconditioned spark plugs before installation. Pre-set gaps may have changed during handling. Use a round wire feeler gauge to be sure of an accurate check, particularly on used plugs. Installing plugs with the wrong gap can cause poor engine performance and may even damage the engine. Gap the spark plugs to the specifications. Refer to Ignition System Specifications. 2. NOTE: - Be sure plug threads smoothly into cylinder head and is fully seated. Use a thread chaser if necessary to clean threads in cylinder head. Cross-threading or failing to fully seat spark plug can cause overheating of plug, exhaust blow-by, or thread damage. Follow the recommended torque specifications carefully. Over or under-tightening can also cause severe damage to engine or spark plug. - Refer to Component Fastener Tightening Notice.

Remove the spark plugs from all the cylinders. 4. Remove the air duct from the throttle body. 5. Block the throttle plate in the open position. 6. Measure the engine compression, using the following procedure: 1. Firmly install the compression gauge to the spark plug hole. 2. Have an assistant crank the engine through at least 4 compression strokes in the testing cylinder. 3. Record the readings on the gauge at each stroke. 4. Disconnect the gauge. 5. Repeat the compression test for each cylinder. 7. Record the compression readings from all of the cylinders. * The lowest reading should not be less than 70 percent of the highest reading. * No cylinder reading should be less than 689 kPa (100 psi). 8. The following list contains examples of the possible measurements: * When the compression measurement is normal, the compression builds up quickly and evenly to the specified compression on each cylinder. * When the compression is low on the first stroke and tends to build up on the following strokes, but does not reach the normal compression, the piston rings may be the cause. * If the compression improves considerably with the addition of three squirts of oil, the piston rings may be the cause. * When the compression is low on the first stroke and does not build up in the following strokes, the valves may be the cause. * The addition of oil does not affect the compression, the valves may be the cause. * When the compression is low on two adjacent cylinders, or coolant is present in the crankcase, the head gasket may be the cause. 9. Remove the block from the throttle plate. 10. Install the air duct to the throttle body. 11. Install the spark plugs. 12. Install the Powertrain Control Module (PCM) fuse. 13. Install the ignition fuse to the I/P fuse block.

Leak detection dye P/N 12378563 (J 29545-6) (in Canada P/N 88900915) may cause DEX-COOL(R) coolant to appear green in a black vessel making it appear to be conventional (green) coolant. This may cause a technician to add conventional coolant to a low DEX-COOL(R) system thus contaminating it. The green DEX-COOL(R) appearance is caused by the color of the leak detection dye which alters the color of the DEX-COOL(R) coolant. A new leak detection dye P/N 89022219 (J 46366) (in Canada P/N 89022220) has been released that does not alter the appearance of the DEX-COOL(R) coolant. When adding the new leak detection dye the color of the DEX-COOL(R) coolant will not change. For detecting leaks on any system that uses DEX-COOL(R) leak detection dye P/N 89022219 (in Canada P/N 89022220) should be used. The new leak detection dye can be used with both conventional and DEX-COOL(R) coolant.

Coolant Reimbursement Policy General Motors supports the use of recycled engine coolant for warranty repairs/service, providing a GM approved engine coolant recycling system is used. Recycled coolant will be reimbursed at the GMSPO dealer price for new coolant plus the appropriate mark-up. When coolant replacement is required during a warranty repair, it is crucial that only the relative amount of engine coolant concentrate be charged, not the total diluted volume. In other words: if you are using two gallons of pre-diluted (50:50) recycled engine coolant to service a vehicle, you may request reimbursement for one gallon of GM Goodwrench engine coolant concentrate at the dealer price plus the appropriate warranty parts handling allowance. Licensed Approved DEX-COOL(R) Providers Important: USE OF NON-APPROVED VIRGIN OR RECYCLED DEX-COOL(R) OR DEVIATIONS IN THE FORM OF ALTERNATE CHEMICALS OR ALTERATION OF EQUIPMENT, WILL VOID THE GM ENDORSEMENT, MAY DEGRADE COOLANT SYSTEM INTEGRITY AND PLACE THE COOLING SYSTEM WARRANTY UNDER JEOPARDY. Shown in Table 1 are the only current licensed and approved providers of DEX-COOL(R). Products that are advertised as "COMPATIBLE" or "RECOMMENDED" for use with DEX-COOL(R) have not been tested or approved by General Motors. Non-approved coolants may degrade the Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Coolant > Component Information > Technical Service Bulletins > Cooling System - DEX-COOL(R) Coolant Leak Detection Dye > Page 3855 coolant system integrity and will no longer be considered a 5 yr/150,000 mile (240,000 km) coolant. Coolant Removal Services/Recycling The tables include all coolant recycling processes currently approved by GM. Also included is a primary phone number and demographic information. Used DEX-COOL(R) can be combined with used conventional coolant (green) for recycling. Depending on the recycling service and/or equipment, it is then designated as a conventional 2 yr/30,000 mile (50,000 km) coolant or DEX-COOL(R) 5 yr/150,000 mile (240,000 km) coolant. Recycled coolants as designated in this bulletin may be used during the vehicle(s) warranty period. DEX-COOL(R) Recycling The DEX-COOL(R) recycling service listed in Table 2 has been approved for recycling waste engine coolants (DEX-COOL) or conventional) to DEX-COOL(R) with 5 yr/150,000 mile (240,000 km) usability. Recycling Fluid Technologies is the only licensed provider of Recycled DEX-COOL(R) meeting GM6277M specifications and utilizes GM approved inhibitor packages. This is currently a limited program being monitored by GM Service Operations which will be expanded as demand increases. Conventional (Green) Recycling Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Coolant > Component Information > Technical Service Bulletins > Cooling System - DEX-COOL(R) Coolant Leak Detection Dye > Page 3856 Processes shown in the Table 3 are capable of recycling waste engine coolants (DEX-COOL(R) or conventional) to a conventional (green) coolant. Recycling conventional coolant can be accomplished at your facility by a technician using approved EQUIPMENT (listed by model number in Table 3), or by an approved coolant recycling SERVICE which may recycle the coolant at your facility or at an offsite operation. Refer to the table for GM approved coolant recyclers in either of these two categories. Should you decide to recycle the coolant yourself, strict adherence to the operating procedures is imperative. Use ONLY the inhibitor chemicals supplied by the respective (GM approved) recycling equipment manufacturer. Sealing Tablets Cooling System Sealing Tablets (Seal Tabs) should not be used as a regular maintenance item after servicing an engine cooling system. Discoloration of coolant can occur if too many seal tabs have been inserted into the cooling system. This can occur if seal tabs are repeatedly used over the service life of a vehicle. Where appropriate, seal tabs may be used if diagnostics fail to repair a small leak in the cooling system. When a condition appears in which seal tabs may be recommended, a specific bulletin will be released describing their proper usage. Water Quality The integrity of the coolant is dependent upon the quality of DEX-COOL(R) and water. DEX-COOL(R) is a product that has enhanced protection capability as well as an extended service interval. These enhanced properties may be jeopardized by combining DEX-COOL(R) with poor quality water. If you suspect the water in your area of being poor quality, it is recommended you use distilled or de-ionized water with DEX-COOL(R). "Pink" DEX-COOL(R) DEX-COOL(R) is orange in color to distinguish it from other coolants. Due to inconsistencies in the mixing of the dyes used with DEX-COOL(R), some batches may appear pink after time. The color shift from orange to pink does not affect the integrity of the coolant, and still maintains the 5 yr/150,000 mile (240,000 km) service interval. Back Service Only use DEX-COOL(R) if the vehicle was originally equipped with DEX-COOL(R). Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Coolant > Component Information > Technical Service Bulletins > Cooling System - DEX-COOL(R) Coolant Leak Detection Dye > Page 3857 Contamination Mixing conventional green coolant with DEX-COOL(R) will degrade the service interval from 5 yrs./150,000 miles (240,000 km) to 2 yrs./30,000 miles (50,000 km) if left in the contaminated condition. If contamination occurs, the cooling system must be flushed twice immediately and re-filled with a 50/50 mixture of DEX-COOL(R) and clean water in order to preserve the enhanced properties and extended service interval of DEX-COOL(R). After 5 years/150,000 miles (240,000 km) After 5 yrs/150,000 miles (240,000 km), the coolant should be changed, preferably using a coolant exchanger. If the vehicle was originally equipped with DEX-COOL(R) and has not had problems with contamination from non-DEX-COOL(R) coolants, then the service interval remains the same, and the coolant does not need to be changed for another 5 yrs/150,000 miles (240,000 km) Equipment (Coolant Exchangers) The preferred method of performing coolant replacement is to use a coolant exchanger. A coolant exchanger can replace virtually all of the old coolant with new coolant. Coolant exchangers can be used to perform coolant replacement without spillage, and facilitate easy waste collection. They can also be used to lower the coolant level in a vehicle to allow for less messy servicing of cooling system components. It is recommended that you use a coolant exchanger with a vacuum feature facilitates removing trapped air from the cooling system. This is a substantial time savings over repeatedly thermo cycling the vehicle and topping-off the radiator. The vacuum feature also allows venting of a hot system to relieve system pressure. Approved coolant exchangers are available through the GMDE (General Motors Dealer Equipment) program. For refilling a cooling system that has been partially or fully drained for repairs other than coolant replacement, the Vac-N-Fill Coolant Refill Tool (GE-47716) is recommended to facilitate removal of trapped air from the cooling system during refill.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Coolant > Component Information > Specifications > Capacity Specifications > Page 3860 Coolant: Fluid Type Specifications ENGINE COOLANT The cooling system in your vehicle is filled with DEX-COOL engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL extended life coolant. A 50/50 mixture of clean, drinkable water and DEX-COOL coolant will: - Give freezing protection down to -34°F (-37°C). - Give boiling protection up to 265°F (129°C). - Protect against rust and corrosion. - Help keep the proper engine temperature. - Let the warning lights and gages work as they should. NOTICE: Using coolant other than DEX-COOL may cause premature engine, heater core or radiator corrosion. In addition, the engine coolant may require changing sooner, at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Any repairs would not be covered by your warranty. Always use DEX-COOL (silicate-free) coolant in your vehicle. WHAT TO USE Use a mixture of one-half clean, drinkable water and one-half DEX-COOL coolant which won't damage aluminum parts. If you use this coolant mixture, you don't need to add anything else. CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle's coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you would not get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOL coolant. NOTICE: If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost would not be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts. If you have to add coolant more than four times a year, check your cooling system. NOTICE: If you use the proper coolant, you do not have to add extra inhibitors or additives which claim to improve the system. These can be harmful.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Heater Core > Component Information > Technical Service Bulletins > Cooling System, A/C - Aluminum Heater Cores/Radiators Heater Core: Technical Service Bulletins Cooling System, A/C - Aluminum Heater Cores/Radiators INFORMATION Bulletin No.: 05-06-02-001A Date: July 16, 2008 Subject: Information On Aluminum Heater Core and/or Radiator Replacement Models: 2005 and Prior GM Passenger Cars and Light Duty Trucks (including Saturn) 2003-2005 HUMMER H2 Supercede: This bulletin is being revised to update the Warranty Information. Please discard Corporate Bulletin Number 05-06-02-001 (Section 06 - Engine/Propulsion System). Important: 2004-05 Chevrolet Aveo (Pontiac Wave, Canada Only) does not use DEX-COOL(R). Refer to the flushing procedure explained later in this bulletin. The following information should be utilized when servicing aluminum heater core and/or radiators on repeat visits. A replacement may be necessary because erosion, corrosion, or insufficient inhibitor levels may cause damage to the heater core, radiator or water pump. A coolant check should be performed whenever a heater core, radiator, or water pump is replaced. The following procedures/ inspections should be done to verify proper coolant effectiveness. Caution: To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if the radiator cap or surge tank cap is removed while the engine and radiator are still hot. Important: If the vehicle's coolant is low, drained out, or the customer has repeatedly added coolant or water to the system, then the system should be completely flushed using the procedure explained later in this bulletin. Technician Diagnosis ^ Verify coolant concentration. A 50% coolant/water solution ensures proper freeze and corrosion protection. Inhibitor levels cannot be easily measured in the field, but can be indirectly done by the measurement of coolant concentration. This must be done by using a Refractometer J 23688 (Fahrenheit scale) or J 26568 (centigrade scale), or equivalent, coolant tester. The Refractometer uses a minimal amount of coolant that can be taken from the coolant recovery reservoir, radiator or the engine block. Inexpensive gravity float testers (floating balls) will not completely analyze the coolant concentration fully and should not be used. The concentration levels should be between 50% and 65% coolant concentrate. This mixture will have a freeze point protection of -34 degrees Fahrenheit (-37 degrees Celsius). If the concentration is below 50%, the cooling system must be flushed. ^ Inspect the coolant flow restrictor if the vehicle is equipped with one. Refer to Service Information (SI) and/or the appropriate Service Manual for component location and condition for operation. ^ Verify that no electrolysis is present in the cooling system. This electrolysis test can be performed before or after the system has been repaired. Use a digital voltmeter set to 12 volts. Attach one test lead to the negative battery post and insert the other test lead into the radiator coolant, making sure the lead does not touch the filler neck or core. Any voltage reading over 0.3 volts indicates that stray current is finding its way into the coolant. Electrolysis is often an intermittent condition that occurs when a device or accessory that is mounted to the radiator is energized. This type of current could be caused from a poorly grounded cooling fan or some other accessory and can be verified by watching the volt meter and turning on and off various accessories or engage the starter motor. Before using one of the following flush procedures, the coolant recovery reservoir must be removed, drained, cleaned and reinstalled before refilling the system. Notice: ^ Using coolant other than DEX‐COOL(R) may cause premature engine, heater core or radiator corrosion. In addition, the engine coolant may require changing sooner, at 30,000 miles (50,000 km) or 24 months, whichever occurs first. Any repairs would not be covered by your warranty. Always use DEX‐COOL(R) (silicate free) coolant in your vehicle. ^ If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost would not be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Heater Core > Component Information > Technical Service Bulletins > Cooling System, A/C - Aluminum Heater Cores/Radiators > Page 3923 Flushing Procedures using DEX-COOL(R) Important: The following procedure recommends refilling the system with DEX-COOL(R), P/N 12346290 (in Canada, use P/N 10953464), GM specification 6277M. This coolant is orange in color and has a service interval of 5 years or 240,000 km (150,000 mi). However, when used on vehicles built prior to the introduction of DEX-COOL(R), maintenance intervals will remain the same as specified in the Owner's Manual. ^ If available, use the approved cooling system flush and fill machine (available through the GM Dealer Equipment Program) following the manufacturer's operating instructions. ^ If approved cooling system flush and fill machine is not available, drain the coolant and dispose of properly following the draining procedures in the appropriate Service Manual. Refill the system using clear, drinkable water and run the vehicle until the thermostat opens. Repeat and run the vehicle three (3) times to totally remove the old coolant or until the drained coolant is almost clear. Once the system is completely flushed, refill the cooling system to a 50%-60% concentration with DEX‐COOL(R), P/N 12346290 (in Canada, use P/N 10953464), GM specification 6277M, following the refill procedures in the appropriate Service Manual. If a Service Manual is not available, fill half the capacity of the system with 100% DEX-COOL(R), P/N 12346290 (in Canada, use P/N 10953464), GM specification 6277M. Then slowly add clear, drinkable water (preferably distilled) to the system until the level of the coolant mixture has reached the base of the radiator neck. Wait two (2) minutes and reverify the coolant level. If necessary, add clean water to restore the coolant to the appropriate level. Once the system is refilled, reverify the coolant concentration using a Refractometer J 23688 (Fahrenheit scale) or J 26568 (centigrade scale) coolant tester, or equivalent. The concentration levels should be between 50% and 65%. Flushing Procedures using Conventional Silicated (Green Colored) Coolant Important: 2004-2005 Chevrolet Aveo (Pontiac Wave, Canada Only) does not use DEX‐COOL(R). The Aveo and Wave are filled with conventional, silicated engine coolant that is blue in color. Silicated coolants are typically green in color and are required to be drained, flushed and refilled every 30,000 miles (48,000 km). The Aveo and Wave are to be serviced with conventional, silicated coolant. Use P/N 12378560 (1 gal) (in Canada, use P/N 88862159 (1 L). Refer to the Owner's Manual or Service Information (SI) for further information on OEM coolant. Important: Do not mix the OEM orange colored DEX-COOL(R) coolant with green colored coolant when adding coolant to the system or when servicing the vehicle's cooling system. Mixing the orange and green colored coolants will produce a brown coolant which may be a customer dissatisfier and will not extend the service interval to that of DEX-COOL(R). Conventional silicated coolants offered by GM Service and Parts Operations are green in color. ^ If available, use the approved cooling system flush and fill machine (available through the GM Dealer Equipment Program) following the manufacturer's operating instructions. ^ If approved cooling systems flush and fill machine is not available, drain coolant and dispose of properly following the draining procedures in appropriate Service Manual. Refill the system using clear, drinkable water and run vehicle until thermostat opens. Repeat and run vehicle three (3) times to totally remove old coolant or until drained coolant is almost clear. Once the system is completely flushed, refill the cooling system to a 50%-60% concentration with a good quality ethylene glycol base engine coolant, P/N 12378560, 1 gal (in Canada, use P/N 88862159 1 L), conforming to GM specification 1825M, or recycled coolant conforming to GM specification 1825M, following the refill procedures in the appropriate Service Manual. If a Service Manual is not available, fill half the capacity of the system with 100% good quality ethylene glycol base (green colored) engine coolant, P/N 12378560 1 gal., (in Canada, use P/N 88862159 1 L) conforming to GM specification 1825M. Then slowly add clear, drinkable water (preferably distilled) to system until the level of the coolant mixture has reached the base of the radiator neck. Wait two (2) minutes and recheck coolant level. If necessary, add clean water to restore coolant to the appropriate level. Once the system is refilled, recheck the coolant concentration using a Refractometer J 23688 (Fahrenheit scale) or J 26568 (centigrade scale) coolant tester, or equivalent. Concentration levels should be between 50% and 65%.

Please discard Corporate Bulletin Number 06-06-01-010 (Section 06 - Engine/Propulsion System). Certain 2004-2008 General Motors products may be equipped with a new style of catalytic converter technically known as the close-coupled catalytic converter providing quick catalyst warm-up resulting in lower tail pipe emissions earlier in the vehicle operating cycle. If an engine breakdown or non-function were to occur (such as broken intake/exhaust valve or piston) debris may be deposited in the converter through engine exhaust ports. If the engine is non-functioning due to a severe overheat event damage to the ceramic "brick" internal to the catalytic converter may occur. This may result in ceramic debris being drawn into the engine through the cylinder head exhaust ports. If a replacement engine is installed in either of these instances the replacement engine may fail due to the debris being introduced into the combustion chambers when started. When replacing an engine for a breakdown or non-function an inspection of the catalytic converters and ALL transferred components (such as exhaust/ intake manifolds) should be performed. Any debris found should be removed. In cases of engine failure due to severe overheat dealers should also inspect each catalytic converter for signs of melting or cracking of the ceramic "brick". If damage is observed the converter should be replaced.

The draw may be steady or may drop down to a low milliamp reading for 1-2 seconds and then rise back up to the 4.1 amp range. If this amp draw condition is observed, check for aftermarket accessories or an improperly installed GM accessory that is wired into circuit 6815 (orange wire) for courtesy lamps. Anytime aftermarket accessories are installed into the courtesy lamp circuit, it can cause the inadvertent power timer in the body control module (BCM) to keep resetting. The BCM will remain awake and cause the draw of approximately 4.1 amps. When servicing a vehicle with this concern, back out pin 1 of the connector 2 at the BCM and see if the draw goes away.

The draw may be steady or may drop down to a low milliamp reading for 1-2 seconds and then rise back up to the 4.1 amp range. If this amp draw condition is observed, check for aftermarket accessories or an improperly installed GM accessory that is wired into circuit 6815 (orange wire) for courtesy lamps. Anytime aftermarket accessories are installed into the courtesy lamp circuit, it can cause the inadvertent power timer in the body control module (BCM) to keep resetting. The BCM will remain awake and cause the draw of approximately 4.1 amps. When servicing a vehicle with this concern, back out pin 1 of the connector 2 at the BCM and see if the draw goes away. If the draw goes away, check for an aftermarket accessory (Lojack, non-factory DVD system, alarm, etc.) that is improperly installed in circuit 6815.

Some technicians may experience an unsuccessful body control module (BCM) reprogramming event, when choosing the Reprogram ECU selection on the Service Programming System (SPS). The technician may also notice that when attempting to reprogram the BCM again after this incident has occurred, the BCM may not complete the programming event. This condition may be caused by the following: - A reprogramming event that was interrupted due to a lack of communication between the vehicle and the TIS2WEB terminal. - The vehicle experienced low system voltage during the reprogramming event. Important Do not replace the BCM for this condition. SPS Programming Process Selection Perform this procedure first. 1. If reprogramming has failed during the initial reprogramming event, back out of the SPS application completely. 2. Re-select SPS from the TIS2WEB terminal application. 3. When selecting the Programming Process , choose Replace and Program ECU , even though a new BCM is NOT being installed. 4. Reprogram the BCM using the Service Programming System (SPS) with the latest calibration available on TIS2WEB. Refer to the SPS procedures in SI. When using a multiple diagnostic interface (MDI) for reprogramming, ensure that it is updated with the latest software version. When using a Tech 2(R) for reprogramming, ensure that it is updated with the latest software version.

Please discard Corporate Bulletin Number 04-06-04-054A (Section 06 - Engine/Propulsion System). The recent rise and expansion of companies selling non-GM parts and accessories has made it necessary to issue this reminder to dealers regarding GM's policy on the use and installation of these aftermarket components. When a dealer is performing a repair under the New Vehicle Limited Warranty, they are required to use only genuine GM or GM-approved parts and accessories. This applies to all warranty repairs, special policy repairs or any repairs paid for by GM. Parts and accessories advertised as being "the same" as parts manufactured by GM, but not sold through GM, do not qualify for use in warranty repairs, special policy repairs or any repairs paid for by GM. During a warranty repair, if a GM original equipment part is not available through GM Customer Care and Aftersales (GM CC&A;), ACDelco(R) distributors, other GM dealers or approved sources, the dealer is to obtain comparable, non-GM parts and clearly indicate, in detail, on the repair order the circumstances surrounding why non-GM parts were used. The dealer must give customers written notice, prior to the sale or service, that such parts or accessories are not marketed or warranted by General Motors. It should also be noted that dealers modifying new vehicles and installing equipment, parts and accessories obtained from sources not authorized by GM are responsible for complying with the National Traffic and Motor Vehicle Safety Act. Certain non-approved parts or assemblies, installed by the dealer or its agent not authorized by GM, may result in a change to the vehicle's design characteristics and may affect the vehicle's ability to conform to federal law. Dealers must fully understand that non-GM approved parts may not have been validated, tested or certified for use. This puts the dealer at risk for potential liability in the event of a part or vehicle failure. If a GM part failure occurs as the result of the installation or use of a non-GM approved part, the warranty will not be honored. A good example of non-authorized modification of vehicles is the result of an ever increasing supply of aftermarket devices available to the customer, which claim to increase the horsepower and torque of the Duramax(TM) Diesel Engines. These include the addition of, but are not limited to one or more of the following modifications: - Propane injection - Nitrous oxide injection - Additional modules (black boxes) that connect to the vehicle wiring systems - Revised engine calibrations downloaded for the engine control module - Calibration modules which connect to the vehicle diagnostic connector - Modification to the engine turbocharger waste gate Although the installation of these devices, or modification of vehicle components, can increase engine horsepower and torque, they may also negatively affect the engine emissions, reliability and/or durability. In addition, other powertrain components, such as transmissions, universal joints, drive shafts, and front/rear axle components, can be stressed beyond design safety limits by the installation of these devices. General Motors does not support or endorse the use of devices or modifications that, when installed, increase the engine horsepower and torque. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED dealer warranty claim submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM (aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed. Refer to the latest version of Bulletin 09-06-04-026 (V8 Gas Engines) or 06-06-01-007 (Duramax(TM) Diesel Engines) for more information on dealer requirements for calibration verification. These same policies apply as they relate to the use of non-GM accessories. Damage or failure from the use or installation of a non-GM accessory will not be covered under warranty. Failure resulting from the alteration or modification of the vehicle, including the cutting, welding or disconnecting of the vehicle's original equipment parts and components will void the warranty. Additionally, dealers will NOT be reimbursed or compensated by GM in the event of any legal inquiry at either the local, state or federal level that Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Technical Service Bulletins > Engine Controls - Aftermarket Accessory Usage > Page 4090 results from the alteration or modification of a vehicle using non-GM approved parts or accessories. Dealers should be especially cautious of accessory companies that claim the installation of their product will not void the factory warranty. Many times these companies have even given direction on how to quickly disassemble the accessory in an attempt to preclude the manufacturer from finding out that is has been installed. Any suspect repairs should be reviewed by the Fixed Operations Manager (FOM), and in Canada by the Warranty Manager (WM) for appropriate repair direction. If it is decided that a goodwill repair is to be made on the vehicle, even with the installation of such non-GM approved components, the customer is to be made aware of General Motors position on this issue and is to sign the appropriate goodwill documentation required by General Motors. It is imperative for dealers to understand that by installing such devices, they are jeopardizing not only the warranty coverage, but also the performance and reliability of the customer's vehicle.

For Duramax(TM) diesel powered engines, refer to the latest version of Corporate Bulletin Number 08-06-04-006G. Supercede: This bulletin is being revised to add the 2011 model year. Please discard Corporate Bulletin Number 09-06-04-026A (Section 06 - Engine/Propulsion System). General Motors is identifying an increasing number of engine, transmission and catalytic converter part failures that are the result of non-GM (aftermarket) engine and transmission control calibrations being used. When alteration to the GM-released engine or transmission control calibrations occurs, it subjects powertrain and driveline components (engine , transmission, transfer case, driveshaft and rear axle) to stresses that were not tested by General Motors. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED dealer warranty claim submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM (aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed. Warranty coverage is based on the equipment and calibrations that were released on the vehicle at time of sale, or subsequently updated by GM. That's because GM testing and validation matches the calibration to a host of criteria that is essential to assure reliability, durability and emissions performance over the life of the warranty coverage and beyond. Stresses resulting from calibrations different from those tested and released by GM can damage or weaken components, leading to poor performance and or shortened life. Additionally, non-GM (aftermarket) issued engine control modifications often do not meet the same emissions performance standards as GM issued calibrations. Depending on state statutes, individuals who install engine control module calibrations that put the vehicle outside the parameters of emissions certification standards may be subject to fines and/or penalties. This bulletin outlines a procedure to identify the presence of non-GM (aftermarket) calibrations. GM recommends performing this check whenever a hard part failure is seen on internal engine or transmission components, or before an engine assembly or transmission assembly is being replaced under warranty. It is also recommended that the engine calibration verification procedure be performed whenever diagnostics indicate that catalytic converter replacement is indicated. The PQC has a process to confirm the ECM/PCM calibration is GM issued. The PQC will require a picture of the engine calibration verification screen, as outlined in this bulletin, before authorizing any V8 gas powered engine replacement. If a non-GM calibration is found and verification has taken place through GM, the remaining powertrain and driveline warranty will be blocked and notated in GMVIS and the dealership will be notified. This block prevents any UNAUTHORIZED warranty claim submission. 1. Connect the Tech 2(R) to the vehicle. 2. Go to: Diagnostics and build the vehicle. 3. Select: Powertrain. 4. Select: Engine. 5. *Select: Engine Control Module or PCM. 6. *Select: Module ID Information or I/M Information System if the Module ID Information selection is not available. 7. *If "I/M information System" was selected, it may be necessary to select "Vehicle Information" in order to display the calibration information. ‹› If the CVN information is displayed as "N/A", it will be necessary to contact the TCSC to obtain the CVN information.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 4108 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 4109 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 4110 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 4112 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 4113 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 4114 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC.

Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 4116 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 4117 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 4181 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 4182 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

OBD II diagnostics monitor the system performance and a diagnostic trouble code (DTC) sets if the system performance degrades.The malfunction indicator lamp (MIL) operation and the DTC storage are dictated by the DTC type. A DTC is ranked as a Type A or Type B if the DTC is emissions related. Type C is a non-emissions related DTC.The ECM is in the engine compartment. The ECM is the control center of the engine controls system. The ECM controls the following components: - The fuel injection system - The ignition system - The emission control systems - The on-board diagnostics - The A/C and fan systems - The throttle actuation control (TAC) system The ECM constantly monitors the information from various sensors and other inputs, and controls the systems that affect the vehicle performance and the emissions. The ECM also performs diagnostic tests on various parts of the system. The ECM can recognize operational problems and alert the driver via the MIL. When the ECM detects a malfunction, the ECM stores a DTC. The condition area is identified by the particular DTC that is set. This aids the technician in making repairs. ECM Function The engine control module (ECM) can supply 5 volts or 12 volts to the various sensors or switches. This is done through pull-up resistors to the regulated power supplies within the ECM. In some cases, even an ordinary shop voltmeter will not give an accurate reading because the resistance is too low. Therefore, a DMM with at least 10 megaohms input impedance is required in order to ensure accurate voltage readings.The ECM controls the output circuits by controlling the ground or the power feed circuit through the transistors or a device called an output driver module. EEPROM The electronically erasable programmable read only memory (EEPROM) is a permanent memory that is physically part of the engine control module (ECM). The EEPROM contains program and calibration information that the ECM needs in order to control the powertrain operation.Special equipment, as well as the correct program and calibration for the vehicle, are required in order to reprogram the ECM. Data Link Connector (DLC) The data link connector (DLC) is a 16-pin connector that provides the technician a means of accessing serial data for aid in the diagnosis. This connector allows the technician to use a scan tool in order to monitor the various serial data parameters, and display the DTC information. The DLC is located inside of the drivers compartment, underneath the dash. Malfunction Indicator Lamp (MIL) The malfunction indicator lamp (MIL) is inside of the instrument panel cluster (IPC). The MIL is controlled by the engine control module (ECM) and illuminates when the ECM detects a condition that affects the vehicle emissions. ECM Service Precautions The engine control module (ECM), by design, can withstand the normal current draws that are associated with the vehicle operations. However, care must be used in order to avoid overloading any of these circuits. When testing for opens or shorts, do not ground or apply voltage to any of the ECM circuits unless the diagnostic procedure instructs you to do so. These circuits should only be tested with a DMM. Emissions Diagnosis For State I/M Programs This OBD II equipped vehicle is designed to diagnose any conditions that could lead to excessive levels of the following emissions: - Hydrocarbons (HC) - Carbon monoxide (CO) - Oxides of nitrogen (NOx) - Evaporative emission (EVAP) system losses Should this vehicles on-board diagnostic system (ECM) detect a condition that could result in excessive emissions, the ECM turns ON the malfunction indicator lamp (MIL) and stores a DTC that is associated with the condition. Aftermarket (Add-On) Electrical And Vacuum Equipment NOTE: Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Page 4205 - Do not attach add-on vacuum operated equipment to this vehicle. The use of add-on vacuum equipment may result in damage to vehicle components or systems. - Connect any add-on electrically operated equipment to the vehicle's electrical system at the battery (power and ground) in order to prevent damage to the vehicle. Aftermarket, add-on, electrical and vacuum equipment is defined as any equipment installed on a vehicle after leaving the factory that connects to the vehicles electrical or vacuum systems. No allowances have been made in the vehicle design for this type of equipment. Add-on electrical equipment, even when installed to these strict guidelines, may still cause the powertrain system to malfunction. This may also include equipment not connected to the vehicle electrical system, such as portable telephones and radios. Therefore, the first step in diagnosing any powertrain condition is to eliminate all of the aftermarket electrical equipment from the vehicle. After this is done, if the problem still exists, the problem may be diagnosed in the normal manner. Electrostatic Discharge (ESD) Damage IMPORTANT: In order to prevent possible electrostatic discharge damage to the engine control module (ECM), DO NOT touch the connector pins on the ECM. The electronic components that are used in the control systems are often designed to carry very low voltage. The electronic components are susceptible to damage caused by electrostatic discharge. Less than 100 volts of static electricity can cause damage to some electronic components. There are several ways for a person to become statically charged. The most common methods of charging are by friction and by induction. An example of charging by friction is a person sliding across a car seat.Charging by induction occurs when a person with well insulated shoes stands near a highly charged object and momentarily touches ground. Charges of the same polarity are drained off leaving the person highly charged with the opposite polarity. Static charges can cause damage, therefore, it is important to use care when handling and testing electronic components. Emissions Control Information Label The underhood Vehicle Emissions Control Information Label contains important emission specifications and setting procedures. In the upper left corner is the exhaust emission information. This identifies the year, the manufacturing division of the engine, the displacement of the engine in liters, the class of the vehicle, and type of fuel metering system. There is also an illustrated emission components and vacuum hose schematic. This label is located in the engine compartment of every General Motors vehicle. If the label has been removed, it can be ordered from GM service parts operations (GMSPO). Underhood Inspection IMPORTANT: This inspection is very important and must be done carefully and thoroughly. Perform a careful underhood inspection when performing any diagnostic procedure or diagnosing the cause of an emission test failure. This can often lead to repairing a condition without further steps. Use the following guidelines when performing an inspection: - Inspect all of the vacuum hoses for correct routing, pinches, cuts, or disconnects. - Inspect any hoses that are difficult to see. - Inspect all of the wires in the engine compartment for the following conditions: Burned or chafed spots - Pinched wires - Contact with sharp edges - Contact with hot exhaust manifolds Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Page 4206 Engine Control Module: Service and Repair ENGINE CONTROL MODULE REPLACEMENT NOTE: - Turn the ignition OFF when installing or removing the control module connectors and disconnecting or reconnecting the power to the control module (battery cable, powertrain control module (PCM)/engine control module (ECM)/transaxle control module (TCM) pigtail, control module fuse, jumper cables, etc.) in order to prevent internal control module damage. - Control module damage may result when the metal case contacts battery voltage. DO NOT contact the control module metal case with battery voltage when servicing a control module, using battery booster cables, or when charging the vehicle battery. - In order to prevent any possible electrostatic discharge damage to the control module, do no touch the connector pins or the soldered components on the circuit board. - Remove any debris from around the control module connector surfaces before servicing the control module. Inspect the control module connector gaskets when diagnosing or replacing the control module. Ensure that the gaskets are installed correctly. The gaskets prevent contaminant intrusion into the control module. - The replacement control module must be programmed. IMPORTANT: - It is necessary to record the remaining engine oil life. If the replacement module is not programed with the remaining engine oil life, the engine oil life will default to 100 percent. If the replacement module is not programmed with the remaining engine oil life, the engine oil will need to be changed at 5000 km (3,000 mi) from the last engine oil change. - It is necessary to record the remaining automatic transmission fluid life. If the replacement module is not programed with the remaining automatic transmission fluid life, the automatic transmission fluid life will default to 100 percent. If the replacement module is not programmed with the remaining automatic transmission fluid life, the automatic transmission fluid will need to be changed at 83000 km (50,000 mi) from the last automatic transmission fluid change. Removal Procedure 1. Using a scan tool, retrieve the percentage of remaining engine oil and the remaining automatic transmission fluid life. Record the remaining engine oil and the remaining automatic transmission fluid life. 2. Slide the engine control module (ECM) retainer rearward, disengaging the retainer from the battery shield. 3. Remove the ECM retainer from the top of the battery shield.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4226 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4227 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4228 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4230 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4231 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4232 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4233 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4234 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4299 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4300 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

SIR/SRS Wiring Repairs SIR/SRS WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The Supplemental Inflatable Restraint (SIR) System/Supplemental Restraint System (SRS) requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working with the SIR/SRS, and the wiring components, such as connectors and terminals. IMPORTANT: Do not use the terminals in the kit in order to replace damaged SIR/SRS system terminals. Use either an SIR/SRS pigtail or a terminated lead from the SIR Repair Kit Tray. The tool kit J-38125 contains the following items: - DuraSeal splice sleeves, in order to repair the SIR/SRS wiring - A special crimping tool - A heat torch - An instruction manual The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides the necessary low resistance contact integrity for these sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors SIR/SRS CONNECTOR REPAIR (PLASTIC BODY AND TERMINAL METAL PIN) The terminals in the SIR/SRS system are made with a special plating. This plating provides the necessary contact integrity for the sensitive, low energy circuits. Use the J-38125 SIR/SRS Terminal Repair Kit for repairing SIR/SRS terminals and connectors. Do not substitute any other terminals for those in the repair kit. The J-38125 SIR/SRS Terminal Repair Kit contains: Various terminated leads for sensing and diagnostic module (SDM) terminal replacement - Various connector positive assurance (CPA) locks for SIR/SRS connectors - Base of steering column pigtail connectors part number 12085514 - Yellow vinyl electrical tape Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4305 Pigtail repair packs are available for SIR/SRS connectors with eight or less terminals. Only the connector body is available for connectors with more than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the connector body. SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 4306 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4349 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4350 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4351 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4352 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4353 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4354 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4355 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4356 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4357 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4358 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4422 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4423 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

IMPORTANT: You must perform the following procedures in the order listed. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip keeping all of the wire strands intact. Open the harness by removing any tape. 2. Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. 3. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 4. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent american wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 5. Slide a section of high temperature SCT1 shrink tubing down the length of wire to be spliced. Ensure that the shrink tubing will not interfere with the splice procedure. 6. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 7. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 8. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 9. Insert the wire into the DuraSeal splice sleeve barrel until the wire hits the barrel stop. 10. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4461 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4462 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4463 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4464 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4465 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4466 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4467 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4468 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4469 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4572 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4573 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4574 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4575 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4576 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4577 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4578 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4579 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4580 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. DIAGNOSTIC FAULT INFORMATION TYPICAL SCAN TOOL DATA CIRCUIT/SYSTEM DESCRIPTION The crankshaft position (CKP) sensor circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, low reference circuit and an output signal circuit. The CKP sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 58-tooth reluctor wheel on the crankshaft. Each tooth on the reluctor wheel is spaced at 60-tooth spacing, with 2 missing teeth for the reference gap. The CKP sensor produces an ON/OFF DC voltage of varying frequency, with 58 output pulses per crankshaft revolution. The frequency of the CKP sensor output depends on the velocity of the crankshaft. The CKP sensor sends a digital signal, which represents an image of the crankshaft reluctor wheel, to the ECM as each tooth on the wheel rotates past the CKP sensor. The ECM uses each CKP signal pulse to determine crankshaft speed and decodes the crankshaft reluctor wheel reference gap to identify crankshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses CKP sensor output information to determine the camshaft relative position to the crankshaft, to control camshaft phasing, and to detect cylinder misfire. DIAGNOSTIC AIDS - Inspect the CKP sensor connector and the ECM connector for corrosion. - With a DTC set, the engine may crank for an extended period of time at start-up. CIRCUIT/SYSTEM VERIFICATION If DTC P0641 or P0651 are set diagnose those DTCs first. 1. With the ignition OFF, inspect the engine wiring harnesses carrying the CKP sensor circuits for the following conditions: - Close routing of secondary ignition wires - Close routing of aftermarket electrical equipment - Close to solenoids, motors, and relays - Correct any wire harness routing or component placement conditions, if it is determined to be a possible source of electrical interference. 2. Start the engine. Using the Live Plot function on the scan tool, select the CMP parameter. Change the minimum spec to 400 RPM, and the maximum spec to 4,000 RPM. Select the CKP sensor parameter. Change the minimum spec to 600 RPM, and the maximum spec to 3,300 RPM. 3. Observe the scan tool. 4. Quickly accelerate and release the accelerator pedal several time. Do not exceed 3,200 RPM. The graphed lines on the Live Plot display should track together across the screen. If the vehicle passes the Circuit/System Verification test, operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records data list.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4700 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4701 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4702 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4704 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4705 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4706 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4707 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4708 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4709 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible.

Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4728 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4773 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4774 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

The J-38125 SIR/SRS Terminal Repair Kit contains: Various terminated leads for sensing and diagnostic module (SDM) terminal replacement - Various connector positive assurance (CPA) locks for SIR/SRS connectors - Base of steering column pigtail connectors part number 12085514 - Yellow vinyl electrical tape Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4779 Pigtail repair packs are available for SIR/SRS connectors with eight or less terminals. Only the connector body is available for connectors with more than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the connector body. SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4780 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4821 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4822 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4823 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4824 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4825 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4826 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4827 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4828 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4829 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4830 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4848 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4894 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4895 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

Removing the pigtail or the connector will affect sensor operation. Handle the oxygen sensor carefully. Do not drop the HO2S. Keep the in-line electrical connector and the louvered end free of grease, dirt, or other contaminants. Do not use cleaning solvents of any type. Do not repair the wiring, connector or terminals. Replace the oxygen sensor if the pigtail wiring, connector, or terminal is damaged. This external clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors, or terminals could result in the obstruction of the air reference and degraded sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: * Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor causing poor performance. * Do not damage the sensor pigtail and harness wires in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. * Ensure the sensor or vehicle lead wires are not bent sharply or kinked. Sharp bends or kinks could block the reference air path through the lead wire. * Do not remove or defeat the oxygen sensor ground wire, where applicable. Vehicles that utilize the ground wired sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will cause poor engine performance. * Ensure that the peripheral seal remains intact on the vehicle harness connector in order to prevent damage due to water intrusion. The engine harness may be repaired using Packard's Crimp and Splice Seals Terminal Repair Kit. Under no circumstances should repairs be soldered since this could result in the air reference being obstructed.

Remove the HO2S and visually inspect the portion of the sensor exposed to the exhaust stream in order to check for contamination. If contaminated, the portion of the sensor exposed to the exhaust stream will have a white powdery coating. Silicon contamination causes a high but false HO2S signal voltage (rich exhaust indication). The control module will then reduce the amount of fuel delivered to the engine, causing a severe driveability problem. Eliminate the source of contamination before replacing the oxygen sensor.

Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4934 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4935 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4936 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4937 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4938 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4939 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4940 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4941 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4942 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 4943 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. AFL/ECP Connectors AFL/EPC CONNECTORS TOOLS REQUIRED J-38125 Terminal Repair Kit REMOVAL PROCEDURE Follow the steps below in order to remove terminals from the connector.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5007 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5008 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

Open the harness by removing any tape. 2. Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. 3. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 4. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent american wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 5. Slide a section of high temperature SCT1 shrink tubing down the length of wire to be spliced. Ensure that the shrink tubing will not interfere with the splice procedure. 6. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 7. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 8. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 9. Insert the wire into the DuraSeal splice sleeve barrel until the wire hits the barrel stop. 10. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5056 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5057 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5058 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5060 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5061 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5062 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5063 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle.

This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5130 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5162 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5163 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5164 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5166 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5167 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5168 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC.

Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5170 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5267 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5268 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5269 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5271 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5272 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5273 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5274 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle.

This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5340 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5341 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5372 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5373 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5374 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5376 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5377 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5378 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5379 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle.

This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5445 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5446 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. DIAGNOSTIC FAULT INFORMATION TYPICAL SCAN TOOL DATA CIRCUIT/SYSTEM DESCRIPTION The crankshaft position (CKP) sensor circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, low reference circuit and an output signal circuit. The CKP sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 58-tooth reluctor wheel on the crankshaft. Each tooth on the reluctor wheel is spaced at 60-tooth spacing, with 2 missing teeth for the reference gap. The CKP sensor produces an ON/OFF DC voltage of varying frequency, with 58 output pulses per crankshaft revolution. The frequency of the CKP sensor output depends on the velocity of the crankshaft. The CKP sensor sends a digital signal, which represents an image of the crankshaft reluctor wheel, to the ECM as each tooth on the wheel rotates past the CKP sensor. The ECM uses each CKP signal pulse to determine crankshaft speed and decodes the crankshaft reluctor wheel reference gap to identify crankshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses CKP sensor output information to determine the camshaft relative position to the crankshaft, to control camshaft phasing, and to detect cylinder misfire. DIAGNOSTIC AIDS - Inspect the CKP sensor connector and the ECM connector for corrosion. - With a DTC set, the engine may crank for an extended period of time at start-up. CIRCUIT/SYSTEM VERIFICATION If DTC P0641 or P0651 are set diagnose those DTCs first. 1. With the ignition OFF, inspect the engine wiring harnesses carrying the CKP sensor circuits for the following conditions: - Close routing of secondary ignition wires - Close routing of aftermarket electrical equipment - Close to solenoids, motors, and relays - Correct any wire harness routing or component placement conditions, if it is determined to be a possible source of electrical interference. 2. Start the engine. Using the Live Plot function on the scan tool, select the CMP parameter. Change the minimum spec to 400 RPM, and the maximum spec to 4,000 RPM. Select the CKP sensor parameter. Change the minimum spec to 600 RPM, and the maximum spec to 3,300 RPM. 3. Observe the scan tool. 4. Quickly accelerate and release the accelerator pedal several time. Do not exceed 3,200 RPM. The graphed lines on the Live Plot display should track together across the screen. If the vehicle passes the Circuit/System Verification test, operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records data list.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5510 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5511 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other.

Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5513 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5514 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5515 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5516 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5517 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5518 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5519 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5537 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5538 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5583 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5584 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5585 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

SIR/SRS Wiring Repairs SIR/SRS WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The Supplemental Inflatable Restraint (SIR) System/Supplemental Restraint System (SRS) requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working with the SIR/SRS, and the wiring components, such as connectors and terminals. IMPORTANT: Do not use the terminals in the kit in order to replace damaged SIR/SRS system terminals. Use either an SIR/SRS pigtail or a terminated lead from the SIR Repair Kit Tray. The tool kit J-38125 contains the following items: - DuraSeal splice sleeves, in order to repair the SIR/SRS wiring - A special crimping tool - A heat torch - An instruction manual The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides the necessary low resistance contact integrity for these sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors SIR/SRS CONNECTOR REPAIR (PLASTIC BODY AND TERMINAL METAL PIN) The terminals in the SIR/SRS system are made with a special plating. This plating provides the necessary contact integrity for the sensitive, low energy circuits. Use the J-38125 SIR/SRS Terminal Repair Kit for repairing SIR/SRS terminals and connectors.

Only the connector body is available for connectors with more than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the connector body. SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5590 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. CIRCUIT/SYSTEM DESCRIPTION The control module enables the fuel pump relay when the ignition switch is turned ON. The control module will disable the fuel pump relay within 2 seconds unless the control module detects ignition reference pulses. The control module continues to enable the fuel pump relay as long as ignition reference pulses are detected. The control module disables the fuel pump relay within 2 seconds if ignition reference pulses cease to be detected and the ignition remains ON.The fuel system is a returnless on-demand design. The fuel pressure regulator is a part of the primary fuel tank module, eliminating the need for a return pipe from the engine. A returnless fuel system reduces the internal temperature of the fuel tank by not returning hot fuel from the engine to the fuel tank. Reducing the internal temperature of the fuel tank results in lower evaporative emissions. An electric turbine style fuel pump attaches to the primary fuel tank module inside the fuel tank. The fuel pump supplies high pressure fuel through the fuel filter, past the fuel pressure regulator, and through the fuel feed pipe to the fuel injection system. The fuel pressure regulator has a T-joint that diverts the needed fuel to the fuel rail with the unused fuel dropping back into the reservoir of the primary fuel tank module. The primary fuel tank module contains a reverse flow check valve. The check valve and the fuel pressure regulator maintain fuel pressure in the fuel feed pipe and the fuel rail in order to prevent long cranking times. The primary fuel tank module also contains a primary jet pump and a secondary jet pump. Fuel pump flow loss, caused by vapor expulsion in the pump inlet chamber, is diverted to the primary jet pump and the secondary jet pump through a restrictive orifice located on the pump cover. The primary jet pump fills the reservoir of the primary fuel tank module. The secondary jet pump creates a venturi action which causes the fuel to be drawn from the secondary side of the fuel tank, through the fuel transfer pipe, to the primary side of the fuel tank. CIRCUIT/SYSTEM VERIFICATION IMPORTANT: Inspect the fuel system for damage or external leaks before proceeding. - Verify that adequate fuel is in the fuel tank before proceeding. - The fuel pump relay may need to be commanded ON a few times in order to obtain the highest possible fuel pressure. - Before proceeding with this test review the User Manual CH 48027-5 for Safety Information and Instructions. 1. Ignition ON, engine OFF, command the fuel pump relay ON with a scan tool.

Please discard Corporate Bulletin Number 07-08-46-002C (Section 08 - Body and Accessories). Condition Some customers may comment on an audio whine coming from the radio speakers when using the OnStar(R) system. The amplitude and frequency of the whine will change with an increase or decrease in engine speed. Cause This condition may be caused by electrical noise on the OnStar(R) Vehicle Communication Interface Module (VCIM) battery feed wire being passed to the microphone output pins at the radio. Correction Technicians are to install a noise suppression filter, P/N 1224205, into the OnStar(R) battery voltage circuit, a few centimeters (inches) from the VCIM. The filter package has three attached wires - a single yellow wire at one end with a yellow wire and a black wire at the other. Install the single yellow wire side into the battery voltage circuit towards the VCIM. Install the remaining single yellow wire into the battery voltage circuit toward the fuse and the black wire to ground. Important The noise suppression filter is polarity sensitive. The filter is designed to be most effective when the end with the capacitor ground is connected towards the source of the electrical noise. Install the filter in this polarity first. If the noise level is still not satisfactory, try disconnecting the capacitor ground. In some cases, if the first installation does not correct the noise, try reversing the filter polarity (removing the filter, turning it end for end and then reinstalling it) and grounding the capacitor lead.

An incorrect spark plug causes driveability conditions. Refer to Ignition System Specifications for the correct spark plug. - Ensure that the spark plug has the correct heat range. An incorrect heat range causes the following conditions: Spark plug fouling-Colder plug - Pre-ignition causing spark plug and/or engine damage-Hotter plug SPARK PLUG INSPECTION - Inspect the terminal post (1) for damage. Inspect for a bent or broken terminal post (1). - Test for a loose terminal post (1) by twisting and pulling the post. The terminal post (1) should NOT move. - Inspect the insulator (2) for flashover or carbon tracking, soot. This is caused by the electrical charge traveling across the insulator (2) between the terminal post (1) and ground. Inspect for the following conditions: Inspect the spark plug boot for damage. - Inspect the spark plug recess area of the cylinder head for moisture, such as oil, coolant, or water. A spark plug boot that is saturated causes arcing to ground. - Inspect the insulator (2) for cracks. All or part of the electrical charge may arc through the crack instead of the electrodes (3, 4). Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Technical Service Bulletins > Page 5688 - Inspect for evidence of improper arcing. Measure the gap between the center electrode (4) and the side electrode (3) terminals. An excessively wide electrode gap can prevent correct spark plug operation. - Inspect for the correct spark plug torque. Insufficient torque can prevent correct spark plug operation. An over torqued spark plug, causes the insulator (2) to crack. - Inspect for signs of tracking that occurred near the insulator tip instead of the center electrode (4). - Inspect for a broken or worn side electrode (3). - Inspect for a broken, worn, or loose center electrode (4) by shaking the spark plug. A rattling sound indicates internal damage. - A loose center electrode (4) reduces the spark intensity. - Inspect for bridged electrodes (3, 4). Deposits on the electrodes (3, 4) reduce or eliminates the gap. - Inspect for worn or missing platinum pads on the electrodes (3, 4), if equipped. - Inspect for excessive fouling. - Inspect the spark plug recess area of the cylinder head for debris. Dirty or damaged threads can cause the spark plug not to seat correctly during installation. SPARK PLUG VISUAL INSPECTION - Normal operation-Brown to grayish-tan with small amounts of white powdery deposits are normal combustion by-products from fuels with additives. - Carbon fouled-Dry, fluffy, black carbon or soot caused by the following conditions: Rich fuel mixtures Leaking fuel injectors - Excessive fuel pressure - Restricted air filter element - Incorrect combustion - Reduced ignition system voltage output Weak coils - Worn ignition wires - Incorrect spark plug gap - Excessive idling or slow speeds under light loads can keep spark plug temperatures so low that normal combustion deposits may not burn off. - Deposit fouling-Oil, coolant, or additives that include substances such as silicone, very white coating, reduces the spark intensity. Most powdery deposits will not effect spark intensity unless they form into a glazing over the electrode. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Technical Service Bulletins > Page 5689 Spark Plug: Service and Repair SPARK PLUG REPLACEMENT REMOVAL PROCEDURE NOTE: Observe the following service precautions: - Allow the engine to cool before removing the spark plugs. Attempting to remove spark plugs from a hot engine can cause the spark plugs to seize. This can damage the cylinder head threads. - Clean the spark plug recess area before removing the spark plug. Failure to do so can result in engine damage due to dirt or foreign material entering the cylinder head, or in contamination of the cylinder head threads. Contaminated threads may prevent proper seating of the new spark plug. - Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine. 1. Remove the spark plug wires from the spark plugs. 2. Remove the spark plugs (1) from the cylinder head. INSTALLATION PROCEDURE 1. NOTE: It is important to check the gap of all new and reconditioned spark plugs before installation. Pre-set gaps may have changed during handling. Use a round wire feeler gauge to be sure of an accurate check, particularly on used plugs. Installing plugs with the wrong gap can cause poor engine performance and may even damage the engine. Gap the spark plugs to the specifications. Refer to Ignition System Specifications. 2. NOTE: - Be sure plug threads smoothly into cylinder head and is fully seated. Use a thread chaser if necessary to clean threads in cylinder head. Cross-threading or failing to fully seat spark plug can cause overheating of plug, exhaust blow-by, or thread damage. Follow the recommended torque specifications carefully. Over or under-tightening can also cause severe damage to engine or spark plug. - Refer to Component Fastener Tightening Notice.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5717 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5718 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5719 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5720 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5721 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5722 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5723 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5724 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5725 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5726 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5744 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5745 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5790 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5791 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5792 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5797 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5799 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5800 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5801 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5945 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5946 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5947 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5948 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5949 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5950 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5951 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5952 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5953 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5954 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5972 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors.

The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 5973 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6018 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6019 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6020 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent american wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 5. Slide a section of high temperature SCT1 shrink tubing down the length of wire to be spliced. Ensure that the shrink tubing will not interfere with the splice procedure. 6. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 7. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 8. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6056 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6057 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6058 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6059 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6060 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6061 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6062 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6063 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6064 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6065 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6083 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6084 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6129 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6130 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6131 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

SIR/SRS Wiring Repairs SIR/SRS WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The Supplemental Inflatable Restraint (SIR) System/Supplemental Restraint System (SRS) requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working with the SIR/SRS, and the wiring components, such as connectors and terminals. IMPORTANT: Do not use the terminals in the kit in order to replace damaged SIR/SRS system terminals. Use either an SIR/SRS pigtail or a terminated lead from the SIR Repair Kit Tray. The tool kit J-38125 contains the following items: - DuraSeal splice sleeves, in order to repair the SIR/SRS wiring - A special crimping tool - A heat torch - An instruction manual The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides the necessary low resistance contact integrity for these sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors SIR/SRS CONNECTOR REPAIR (PLASTIC BODY AND TERMINAL METAL PIN) The terminals in the SIR/SRS system are made with a special plating. This plating provides the necessary contact integrity for the sensitive, low energy circuits. Use the J-38125 SIR/SRS Terminal Repair Kit for repairing SIR/SRS terminals and connectors.

Only the connector body is available for connectors with more than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the connector body. SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6136 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6139 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. DIAGNOSTIC FAULT INFORMATION TYPICAL SCAN TOOL DATA CIRCUIT/SYSTEM DESCRIPTION The crankshaft position (CKP) sensor circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, low reference circuit and an output signal circuit. The CKP sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 58-tooth reluctor wheel on the crankshaft. Each tooth on the reluctor wheel is spaced at 60-tooth spacing, with 2 missing teeth for the reference gap. The CKP sensor produces an ON/OFF DC voltage of varying frequency, with 58 output pulses per crankshaft revolution. The frequency of the CKP sensor output depends on the velocity of the crankshaft. The CKP sensor sends a digital signal, which represents an image of the crankshaft reluctor wheel, to the ECM as each tooth on the wheel rotates past the CKP sensor. The ECM uses each CKP signal pulse to determine crankshaft speed and decodes the crankshaft reluctor wheel reference gap to identify crankshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses CKP sensor output information to determine the camshaft relative position to the crankshaft, to control camshaft phasing, and to detect cylinder misfire. DIAGNOSTIC AIDS - Inspect the CKP sensor connector and the ECM connector for corrosion. - With a DTC set, the engine may crank for an extended period of time at start-up. CIRCUIT/SYSTEM VERIFICATION If DTC P0641 or P0651 are set diagnose those DTCs first. 1. With the ignition OFF, inspect the engine wiring harnesses carrying the CKP sensor circuits for the following conditions: - Close routing of secondary ignition wires - Close routing of aftermarket electrical equipment - Close to solenoids, motors, and relays - Correct any wire harness routing or component placement conditions, if it is determined to be a possible source of electrical interference. 2. Start the engine. Using the Live Plot function on the scan tool, select the CMP parameter. Change the minimum spec to 400 RPM, and the maximum spec to 4,000 RPM. Select the CKP sensor parameter. Change the minimum spec to 600 RPM, and the maximum spec to 3,300 RPM. 3. Observe the scan tool. 4. Quickly accelerate and release the accelerator pedal several time. Do not exceed 3,200 RPM. The graphed lines on the Live Plot display should track together across the screen. If the vehicle passes the Circuit/System Verification test, operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records data list.

The TAC system performs the following functions: Accelerator pedal position sensing - Throttle positioning to meet driver and engine demands - Throttle position sensing - Internal diagnostics - Cruise control functions - Manage TAC electrical power consumption The TAC system includes the following components: The accelerator pedal position (APP) sensors - The throttle body assembly - The engine control module (ECM) ACCELERATOR PEDAL POSITION (APP) SENSOR The accelerator pedal contains 2 individual accelerator pedal position (APP) sensors within the assembly. The APP sensors 1 and 2 are potentiometer type sensors each with 3 circuits: A 5-volt reference circuit - A low reference circuit - A signal circuit The APP sensors are used to determine the pedal angle. The engine control module (ECM) provides each APP sensor a 5-volt reference circuit and a low reference circuit. The APP sensors provide the ECM with signal voltage proportional to the pedal movement. The APP sensor 1 signal voltage at rest position is less than 1 volt and increases to more than 4 volts as the pedal is actuated. The APP sensor 2 signal voltage at rest position is less than 0.6 volt and increases to more than 2 volts as the pedal is actuated. THROTTLE BODY ASSEMBLY The throttle assembly contains the following components: The throttle blade - The throttle actuator motor - The throttle position (TP) sensor 1 and 2 The throttle body functions similar to a conventional throttle body with the following exceptions: An electric motor opens and closes the throttle valve. - The throttle blade is spring loaded in both directions and the default position is slightly open. - There are 2 individual TP sensors within the throttle body assembly. The TP sensors are used to determine the throttle plate angle. The TP sensors provide the engine control module (ECM) with a signal voltage proportional to throttle plate movement. The TP sensor 1 signal voltage at closed throttle is above 4 volts and decreases as the throttle plate is opened. The TP sensor 2 signal voltage at closed throttle is below 1 volt and increases as the throttle plate is opened. ENGINE CONTROL MODULE The engine control module (ECM) is the control center for the throttle actuator control (TAC) system. The ECM determines the drivers intent and then calculates the appropriate throttle response. The ECM achieves throttle positioning by providing a pulse width modulated voltage to the TAC motor. MODES OF OPERATION Normal Mode During the operation of the throttle actuator control (TAC) system, several modes or functions are considered normal. The following modes may be entered during normal operation: Minimum pedal value-At key-up, the engine control module (ECM) updates the learned minimum pedal value. - Minimum throttle position (TP) values-At key-up, the ECM updates the learned minimum TP value. In order to learn the minimum TP value, the throttle blade is moved to the closed position. - Ice break mode-If the throttle is not able to reach a predetermined minimum throttle position, the ice break mode is entered. During the ice break mode, the ECM commands the maximum pulse width several times to the throttle actuator motor in the closing direction. - Battery saver mode-After a predetermined time without engine RPM, the ECM commands the battery saver mode. During the battery saver mode, the TAC module removes the voltage from the motor control circuits, which removes the current draw used to maintain the idle position and allows the throttle to return to the spring loaded default position. Reduced Engine Power Mode Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Electronic Throttle Actuator > Component Information > Diagrams > Page 6159 When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions: Acceleration limiting-The ECM will continue to use the accelerator pedal for throttle control, however, the vehicle acceleration is limited. - Limited throttle mode-The ECM will continue to use the accelerator pedal for throttle control, however, the maximum throttle opening is limited. - Throttle default mode-The ECM will turn OFF the throttle actuator motor and the throttle will return to the spring loaded default position. - Forced idle mode-The ECM will perform the following actions: Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned OFF - Ignore the accelerator pedal input - Engine shutdown mode-The ECM will disable fuel and de-energize the throttle actuator.

Please discard Corporate Bulletin Number 04-06-04-054A (Section 06 - Engine/Propulsion System). The recent rise and expansion of companies selling non-GM parts and accessories has made it necessary to issue this reminder to dealers regarding GM's policy on the use and installation of these aftermarket components. When a dealer is performing a repair under the New Vehicle Limited Warranty, they are required to use only genuine GM or GM-approved parts and accessories. This applies to all warranty repairs, special policy repairs or any repairs paid for by GM. Parts and accessories advertised as being "the same" as parts manufactured by GM, but not sold through GM, do not qualify for use in warranty repairs, special policy repairs or any repairs paid for by GM. During a warranty repair, if a GM original equipment part is not available through GM Customer Care and Aftersales (GM CC&A;), ACDelco(R) distributors, other GM dealers or approved sources, the dealer is to obtain comparable, non-GM parts and clearly indicate, in detail, on the repair order the circumstances surrounding why non-GM parts were used. The dealer must give customers written notice, prior to the sale or service, that such parts or accessories are not marketed or warranted by General Motors. It should also be noted that dealers modifying new vehicles and installing equipment, parts and accessories obtained from sources not authorized by GM are responsible for complying with the National Traffic and Motor Vehicle Safety Act. Certain non-approved parts or assemblies, installed by the dealer or its agent not authorized by GM, may result in a change to the vehicle's design characteristics and may affect the vehicle's ability to conform to federal law. Dealers must fully understand that non-GM approved parts may not have been validated, tested or certified for use. This puts the dealer at risk for potential liability in the event of a part or vehicle failure. If a GM part failure occurs as the result of the installation or use of a non-GM approved part, the warranty will not be honored. A good example of non-authorized modification of vehicles is the result of an ever increasing supply of aftermarket devices available to the customer, which claim to increase the horsepower and torque of the Duramax(TM) Diesel Engines. These include the addition of, but are not limited to one or more of the following modifications: - Propane injection - Nitrous oxide injection - Additional modules (black boxes) that connect to the vehicle wiring systems - Revised engine calibrations downloaded for the engine control module - Calibration modules which connect to the vehicle diagnostic connector - Modification to the engine turbocharger waste gate Although the installation of these devices, or modification of vehicle components, can increase engine horsepower and torque, they may also negatively affect the engine emissions, reliability and/or durability. In addition, other powertrain components, such as transmissions, universal joints, drive shafts, and front/rear axle components, can be stressed beyond design safety limits by the installation of these devices. General Motors does not support or endorse the use of devices or modifications that, when installed, increase the engine horsepower and torque. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED dealer warranty claim submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM (aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed. Refer to the latest version of Bulletin 09-06-04-026 (V8 Gas Engines) or 06-06-01-007 (Duramax(TM) Diesel Engines) for more information on dealer requirements for calibration verification. These same policies apply as they relate to the use of non-GM accessories. Damage or failure from the use or installation of a non-GM accessory will not be covered under warranty. Failure resulting from the alteration or modification of the vehicle, including the cutting, welding or disconnecting of the vehicle's original equipment parts and components will void the warranty. Additionally, dealers will NOT be reimbursed or compensated by GM in the event of any legal inquiry at either the local, state or federal level that Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Technical Service Bulletins > Engine Controls - Aftermarket Accessory Usage > Page 6169 results from the alteration or modification of a vehicle using non-GM approved parts or accessories. Dealers should be especially cautious of accessory companies that claim the installation of their product will not void the factory warranty. Many times these companies have even given direction on how to quickly disassemble the accessory in an attempt to preclude the manufacturer from finding out that is has been installed. Any suspect repairs should be reviewed by the Fixed Operations Manager (FOM), and in Canada by the Warranty Manager (WM) for appropriate repair direction. If it is decided that a goodwill repair is to be made on the vehicle, even with the installation of such non-GM approved components, the customer is to be made aware of General Motors position on this issue and is to sign the appropriate goodwill documentation required by General Motors. It is imperative for dealers to understand that by installing such devices, they are jeopardizing not only the warranty coverage, but also the performance and reliability of the customer's vehicle.

For Duramax(TM) diesel powered engines, refer to the latest version of Corporate Bulletin Number 08-06-04-006G. Supercede: This bulletin is being revised to add the 2011 model year. Please discard Corporate Bulletin Number 09-06-04-026A (Section 06 - Engine/Propulsion System). General Motors is identifying an increasing number of engine, transmission and catalytic converter part failures that are the result of non-GM (aftermarket) engine and transmission control calibrations being used. When alteration to the GM-released engine or transmission control calibrations occurs, it subjects powertrain and driveline components (engine , transmission, transfer case, driveshaft and rear axle) to stresses that were not tested by General Motors. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED dealer warranty claim submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM (aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed. Warranty coverage is based on the equipment and calibrations that were released on the vehicle at time of sale, or subsequently updated by GM. That's because GM testing and validation matches the calibration to a host of criteria that is essential to assure reliability, durability and emissions performance over the life of the warranty coverage and beyond. Stresses resulting from calibrations different from those tested and released by GM can damage or weaken components, leading to poor performance and or shortened life. Additionally, non-GM (aftermarket) issued engine control modifications often do not meet the same emissions performance standards as GM issued calibrations. Depending on state statutes, individuals who install engine control module calibrations that put the vehicle outside the parameters of emissions certification standards may be subject to fines and/or penalties. This bulletin outlines a procedure to identify the presence of non-GM (aftermarket) calibrations. GM recommends performing this check whenever a hard part failure is seen on internal engine or transmission components, or before an engine assembly or transmission assembly is being replaced under warranty. It is also recommended that the engine calibration verification procedure be performed whenever diagnostics indicate that catalytic converter replacement is indicated. The PQC has a process to confirm the ECM/PCM calibration is GM issued. The PQC will require a picture of the engine calibration verification screen, as outlined in this bulletin, before authorizing any V8 gas powered engine replacement. If a non-GM calibration is found and verification has taken place through GM, the remaining powertrain and driveline warranty will be blocked and notated in GMVIS and the dealership will be notified. This block prevents any UNAUTHORIZED warranty claim submission. 1. Connect the Tech 2(R) to the vehicle. 2. Go to: Diagnostics and build the vehicle. 3. Select: Powertrain. 4.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6187 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6188 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6189 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6191 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6192 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6193 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6194 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6195 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6196 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6214 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6215 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6260 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6261 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6262 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6267 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6269 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6270 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

OBD II diagnostics monitor the system performance and a diagnostic trouble code (DTC) sets if the system performance degrades.The malfunction indicator lamp (MIL) operation and the DTC storage are dictated by the DTC type. A DTC is ranked as a Type A or Type B if the DTC is emissions related. Type C is a non-emissions related DTC.The ECM is in the engine compartment. The ECM is the control center of the engine controls system. The ECM controls the following components: - The fuel injection system - The ignition system - The emission control systems - The on-board diagnostics - The A/C and fan systems - The throttle actuation control (TAC) system The ECM constantly monitors the information from various sensors and other inputs, and controls the systems that affect the vehicle performance and the emissions. The ECM also performs diagnostic tests on various parts of the system. The ECM can recognize operational problems and alert the driver via the MIL. When the ECM detects a malfunction, the ECM stores a DTC. The condition area is identified by the particular DTC that is set. This aids the technician in making repairs. ECM Function The engine control module (ECM) can supply 5 volts or 12 volts to the various sensors or switches. This is done through pull-up resistors to the regulated power supplies within the ECM. In some cases, even an ordinary shop voltmeter will not give an accurate reading because the resistance is too low. Therefore, a DMM with at least 10 megaohms input impedance is required in order to ensure accurate voltage readings.The ECM controls the output circuits by controlling the ground or the power feed circuit through the transistors or a device called an output driver module. EEPROM The electronically erasable programmable read only memory (EEPROM) is a permanent memory that is physically part of the engine control module (ECM). The EEPROM contains program and calibration information that the ECM needs in order to control the powertrain operation.Special equipment, as well as the correct program and calibration for the vehicle, are required in order to reprogram the ECM. Data Link Connector (DLC) The data link connector (DLC) is a 16-pin connector that provides the technician a means of accessing serial data for aid in the diagnosis. This connector allows the technician to use a scan tool in order to monitor the various serial data parameters, and display the DTC information. The DLC is located inside of the drivers compartment, underneath the dash. Malfunction Indicator Lamp (MIL) The malfunction indicator lamp (MIL) is inside of the instrument panel cluster (IPC). The MIL is controlled by the engine control module (ECM) and illuminates when the ECM detects a condition that affects the vehicle emissions. ECM Service Precautions The engine control module (ECM), by design, can withstand the normal current draws that are associated with the vehicle operations. However, care must be used in order to avoid overloading any of these circuits. When testing for opens or shorts, do not ground or apply voltage to any of the ECM circuits unless the diagnostic procedure instructs you to do so. These circuits should only be tested with a DMM. Emissions Diagnosis For State I/M Programs This OBD II equipped vehicle is designed to diagnose any conditions that could lead to excessive levels of the following emissions: - Hydrocarbons (HC) - Carbon monoxide (CO) - Oxides of nitrogen (NOx) - Evaporative emission (EVAP) system losses Should this vehicles on-board diagnostic system (ECM) detect a condition that could result in excessive emissions, the ECM turns ON the malfunction indicator lamp (MIL) and stores a DTC that is associated with the condition. Aftermarket (Add-On) Electrical And Vacuum Equipment NOTE: Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Page 6284 - Do not attach add-on vacuum operated equipment to this vehicle. The use of add-on vacuum equipment may result in damage to vehicle components or systems. - Connect any add-on electrically operated equipment to the vehicle's electrical system at the battery (power and ground) in order to prevent damage to the vehicle. Aftermarket, add-on, electrical and vacuum equipment is defined as any equipment installed on a vehicle after leaving the factory that connects to the vehicles electrical or vacuum systems. No allowances have been made in the vehicle design for this type of equipment. Add-on electrical equipment, even when installed to these strict guidelines, may still cause the powertrain system to malfunction. This may also include equipment not connected to the vehicle electrical system, such as portable telephones and radios. Therefore, the first step in diagnosing any powertrain condition is to eliminate all of the aftermarket electrical equipment from the vehicle. After this is done, if the problem still exists, the problem may be diagnosed in the normal manner. Electrostatic Discharge (ESD) Damage IMPORTANT: In order to prevent possible electrostatic discharge damage to the engine control module (ECM), DO NOT touch the connector pins on the ECM. The electronic components that are used in the control systems are often designed to carry very low voltage. The electronic components are susceptible to damage caused by electrostatic discharge. Less than 100 volts of static electricity can cause damage to some electronic components. There are several ways for a person to become statically charged. The most common methods of charging are by friction and by induction. An example of charging by friction is a person sliding across a car seat.Charging by induction occurs when a person with well insulated shoes stands near a highly charged object and momentarily touches ground. Charges of the same polarity are drained off leaving the person highly charged with the opposite polarity. Static charges can cause damage, therefore, it is important to use care when handling and testing electronic components. Emissions Control Information Label The underhood Vehicle Emissions Control Information Label contains important emission specifications and setting procedures. In the upper left corner is the exhaust emission information. This identifies the year, the manufacturing division of the engine, the displacement of the engine in liters, the class of the vehicle, and type of fuel metering system. There is also an illustrated emission components and vacuum hose schematic. This label is located in the engine compartment of every General Motors vehicle. If the label has been removed, it can be ordered from GM service parts operations (GMSPO). Underhood Inspection IMPORTANT: This inspection is very important and must be done carefully and thoroughly. Perform a careful underhood inspection when performing any diagnostic procedure or diagnosing the cause of an emission test failure. This can often lead to repairing a condition without further steps. Use the following guidelines when performing an inspection: - Inspect all of the vacuum hoses for correct routing, pinches, cuts, or disconnects. - Inspect any hoses that are difficult to see. - Inspect all of the wires in the engine compartment for the following conditions: Burned or chafed spots - Pinched wires - Contact with sharp edges - Contact with hot exhaust manifolds Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Page 6285 Engine Control Module: Service and Repair ENGINE CONTROL MODULE REPLACEMENT NOTE: - Turn the ignition OFF when installing or removing the control module connectors and disconnecting or reconnecting the power to the control module (battery cable, powertrain control module (PCM)/engine control module (ECM)/transaxle control module (TCM) pigtail, control module fuse, jumper cables, etc.) in order to prevent internal control module damage. - Control module damage may result when the metal case contacts battery voltage. DO NOT contact the control module metal case with battery voltage when servicing a control module, using battery booster cables, or when charging the vehicle battery. - In order to prevent any possible electrostatic discharge damage to the control module, do no touch the connector pins or the soldered components on the circuit board. - Remove any debris from around the control module connector surfaces before servicing the control module. Inspect the control module connector gaskets when diagnosing or replacing the control module. Ensure that the gaskets are installed correctly. The gaskets prevent contaminant intrusion into the control module. - The replacement control module must be programmed. IMPORTANT: - It is necessary to record the remaining engine oil life. If the replacement module is not programed with the remaining engine oil life, the engine oil life will default to 100 percent. If the replacement module is not programmed with the remaining engine oil life, the engine oil will need to be changed at 5000 km (3,000 mi) from the last engine oil change. - It is necessary to record the remaining automatic transmission fluid life. If the replacement module is not programed with the remaining automatic transmission fluid life, the automatic transmission fluid life will default to 100 percent. If the replacement module is not programmed with the remaining automatic transmission fluid life, the automatic transmission fluid will need to be changed at 83000 km (50,000 mi) from the last automatic transmission fluid change. Removal Procedure 1. Using a scan tool, retrieve the percentage of remaining engine oil and the remaining automatic transmission fluid life. Record the remaining engine oil and the remaining automatic transmission fluid life. 2. Slide the engine control module (ECM) retainer rearward, disengaging the retainer from the battery shield. 3.

OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6318 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6319 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6320 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6321 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6322 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6323 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6324 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6325 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6326 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6327 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6391 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6392 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6393 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 6394 1. IMPORTANT: You must perform the following procedures in the order listed. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip keeping all of the wire strands intact. Open the harness by removing any tape. 2. Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. 3. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 4. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent american wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 5. Slide a section of high temperature SCT1 shrink tubing down the length of wire to be spliced. Ensure that the shrink tubing will not interfere with the splice procedure. 6. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 7. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 8. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 9. Insert the wire into the DuraSeal splice sleeve barrel until the wire hits the barrel stop. 10. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice.

The modules that need real time communication are attached to the high speed GMLAN network. The body control module (BCM) is the serial data gateway between the networks. The purpose of the gateway is to translate serial data messages between the GMLAN high speed buss and the GMLAN low speed buss. The Controller Area Network (CAN) is another serial data communication network used on this vehicle which is dedicated to the Electronic Brake Control Module (EBCM) subsystem for stabilization. Below are more detailed descriptions of the individual networks. The gateway will interact with each network according to that network's transmission protocol. Refer to Body Control System Description and Operation for more information about the gateway. GMLAN HIGH SPEED CIRCUIT DESCRIPTION The data link connector (DLC) allows a scan tool to communicate with the high speed GMLAN serial data circuit. The serial data is transmitted on two twisted wires that allow speed up to 500 Kb/s. The twisted pair is terminated with two 120 ohms resistors, one is internal to the engine control module (ECM) and the other is after the BCM in either the AWD module or a separate resistor connector assembly. The resistors are used to reduce noise on the High Speed GMLAN buss during normal vehicle operation. The high speed GMLAN is a differential bus. The high speed GMLAN serial data bus (+) and high speed GMLAN serial data (-) are driven to opposite extremes from a rest or idle level. The idle level, which is approximately 2.5 volts, is considered recessive transmitted data and is interpreted as a logic 1. Driving the lines to their extremes, adds one volt to the high speed GMLAN serial data bus (+) and subtracts one volt from the high speed GMLAN serial data bus (-) wire. This dominant state is interpreted as a logic 0. GMLAN network management supports selective start up and is based on virtual networks. A virtual network is a collection of signals started in response to a vehicle event. The starting of a virtual network signifies that a particular aspect of the vehicles functionality has been requested. A virtual network is supported by virtual devices, which represents a collection of signals owned by a single physical device. So, any physical device can have one or more virtual devices. The signal supervision is the process of determining whether an expected signal is being received or not. Failsofting is the ability to substitute a signal with a default value or a default algorithm, in the absence of a valid signal. Some messages are also interpreted as a heartbeat of a virtual device. If such a signal is lost, the application will set a no communication code against the respective virtual device. This code is mapped on the Tech 2 screen as a code against the physical device. NOTE: a loss of serial data DTC does not represent a failure of the module that the code is set in. GMLAN LOW SPEED CIRCUIT DESCRIPTION The data link connector (DLC) allows a scan tool to communicate with the low speed GMLAN serial data circuit. The serial data is transmitted over a single wire to the appropriate control modules. The transmission speed for GMLAN low speed is up to 83.33 Kb/s. Under normal vehicle operating conditions, the speed of the buss is 33.33 Kb/s. This protocol produces a simple pulse train sent out over the GMLAN low speed serial data bus. When a module pulls the buss high, 5 volts, this creates a dominant logic state or 0 on the buss. When the buss is pulled low, 0 volts, it is translated as a recessive logic state or 1. To wake the control modules connected to the GMLAN low speed serial data buss, a voltage wake up pulse is sent out over the buss, the voltage level of the pules is +10 volts. Modules connected to the GMLAN low speed buss can be part of a virtual network as described in the previous paragraph. The modules on the GMLAN low speed serial data buss are connected to the buss in a parallel configuration. CONTROLLER AREA NETWORK (CAN) DESCRIPTION The EBCM communicates with the yaw rate sensor and the steering wheel angle sensor exclusively, when equipped. This serial data system does not communiate with the scan tool however; there are loss of communication DTCs for this system which set in the EBCM. The yaw rate sensor and the steering wheel angle sensors are in effect modules, exchanging essential information with the EBCM. For more information about these sensors refer to ABS Description and Operation. DATA LINK CONNECTOR (DLC) The data link connector (DLC) is a standardized 16-cavity connector. Connector design and location is dictated by an industry wide standard, and is required to provide the following: Pin 1 GMLAN low speed communications terminal - Pin 4 Scan tool power ground terminal - Pin 5 Common signal ground terminal - Pin 6 High speed GMLAN serial data bus (+) terminal - Pin 7 - Pin 14 High speed GMLAN serial data bus (-) terminal - Pin 16 Scan tool power, battery positive voltage terminal SERIAL DATA REFERENCE The scan tool communicates over the various busses on the vehicle. When a scan tool is installed on a vehicle, the scan tool will try to communicate with every module that could be optioned into the vehicle. If an option is not installed on the vehicle, the scan tool will display No Comm for that options control module. In order to avert misdiagnoses of No Communication with a specific module, refer to Data Link References for a list of modules, the busses they communicate with, and the RPO codes for a specific module.

CIRCUIT/SYSTEM DESCRIPTION Modules connected to the high speed GMLAN serial data circuits monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules when the ignition switch is in any position other than OFF. The high speed GMLAN serial data circuits must be operational for the vehicle to start due to body control module (BCM) and engine control module (ECM)/powertrain control module (PCM) communications. The theft deterrent module and ECM/PCM exchange information using the BCM as the gateway module allowing communication between the high and low speed serial data busses. The low speed GMLAN serial data circuit must also be operational for vehicle starting. DIAGNOSTIC AIDS - Use the Data Link References to identify the high speed GMLAN serial data modules. - This test is used for a total high speed GMLAN communication failure. If only 1 module is not communicating and sets no DTC, ensure that the Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview > Page 6413 vehicle is equipped with the module, then use DTC U0100-U0299 for diagnostics. - An open in the DLC ground circuit terminal 5 will allow the scan tool to operate to set up the vehicle on the tool and then not communicate with the vehicle. When the scan tool is to the point of communicating with the vehicle, a message on the scan tool will indicate "no CANdi module detected" and will not communicate. - The engine will not start when there is a total malfunction of the high speed GMLAN serial data bus.The following conditions may cause a total loss of high speed GMLAN data communication: A short between high speed GMLAN (+) and high speed GMLAN (-) circuits - Any of the high speed GMLAN serial data circuits shorted to ground or voltage - A module internal malfunction that causes a short to voltage or ground on the high speed GMLAN circuits - Use the DMM MIN/MAX function to capture/locate intermittent conditions.

CIRCUIT/SYSTEM DESCRIPTION Modules connected to the low speed GMLAN serial data circuit monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules when the ignition switch is in any position other than OFF. The low speed GMLAN serial data circuit must be operational for the vehicle to start so the vehicle theft deterrent (VTD) module and body control module (BCM) can communicate. The low speed GMLAN serial data circuit uses SP200 as the common connection between the modules and the data link connector (DLC). DIAGNOSTIC AIDS - Use the Data Link References to identify the low speed GMLAN serial data modules. - This test is used for a total low speed GMLAN communication failure. If only 1 module is not communicating and sets no DTC, ensure that the vehicle is equipped with the module, then use DTC U0100-U0299 for diagnostics. - An open in the low speed GMLAN serial data circuit between the splice pack and a module will only effect the specific module. This type of failure will set a loss of communication DTC for each module effected, and the other modules will still communicate. - An open in the DLC ground circuit terminal 5 will allow the scan tool to operate to set up the vehicle on the tool and then not communicate with the vehicle. When the scan tool is to the point of communicating with the vehicle, a message on the scan tool will indicate "no CANdi module detected" and will not communicate. - An open between the DLC and SP200 will only effect the communication with the scan tool. The vehicle modules will still communicate, and the vehicle will start. - The engine will not start when there is a total malfunction of the low speed GMLAN serial data circuit.The following conditions may cause a total loss of low speed GMLAN data communication: The low speed GMLAN serial data circuit shorted to ground or voltage. - A module internal malfunction that causes a short to voltage or ground on the low speed GMLAN circuit. - Use the DMM MIN/MAX function to capture/locate intermittent conditions. CIRCUIT/SYSTEM TESTING 1. Test for less than 1 ohm of resistance between the DLC ground circuit terminal 5 and ground. - If greater than 1 ohm, test the ground circuit for open/high resistance. 2. Ignition OFF, disconnect the harness connector (splice pack comb) at SP 200. Install a 3-amp fused jumper wire between pin A and pin M of SP 200, harness side. 3. Ignition ON, with a scan tool, attempt to communicate with the BCM. Communication should be available. - If no communication, test the following circuits: serial data circuit for a short to ground, a short to voltage or an open/high resistance between the BCM and DLC, BCM voltage inputs for open/high resistance or short to ground, BCM grounds for open/high resistance. If the circuits test normal, replace the BCM. 4. Install another 3-amp fused jumper wire to pin A of SP 200, harness side. 5. Use the other end of the jumper wire to connect all other pins, harness side, one at a time and verify that low speed communication remains available to the BCM. If low speed communication is interrupted after connecting an individual module at SP 200, test the serial data circuit between SP 200 and the last module connected for a short to ground and short to voltage. If the circuit tests normal, replace the module that caused no communication.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6434 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6435 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6436 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6437 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6438 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6439 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6440 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6441 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6442 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6443 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6461 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6462 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

Continue to apply pressure and rock the cover until the second locking leg is unseated. Repeat procedure for the other side of the dress cover and remove the cover. 9. Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6465 3. Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6507 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6508 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6509 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6518 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6519 4. IMPORTANT: Apply the mylar tape with the aluminum side inward. This ensures good electrical contact with the drain wire. Re-assemble the cable. Rewrap the conductors with the mylar tape. - Use caution not to wrap the drain wire in the tape (1). - Follow the splicing instructions for copper wire and splice the drain wire. - Wrap the drain wire around the conductors and tape with mylar tape. 5. Tape over the entire cable. Use a winding motion when you apply the tape.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6558 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6559 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6560 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6561 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6562 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6563 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6564 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6565 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6566 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6567 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6585 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6586 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6589 3. Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1. Slide the new terminal into the correct cavity at the back of the connector. 2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire. 3.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6631 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6632 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6633 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6642 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6643 4. IMPORTANT: Apply the mylar tape with the aluminum side inward. This ensures good electrical contact with the drain wire. Re-assemble the cable. Rewrap the conductors with the mylar tape. - Use caution not to wrap the drain wire in the tape (1). - Follow the splicing instructions for copper wire and splice the drain wire. - Wrap the drain wire around the conductors and tape with mylar tape. 5. Tape over the entire cable. Use a winding motion when you apply the tape.

Removing the pigtail or the connector will affect sensor operation. Handle the oxygen sensor carefully. Do not drop the HO2S. Keep the in-line electrical connector and the louvered end free of grease, dirt, or other contaminants. Do not use cleaning solvents of any type. Do not repair the wiring, connector or terminals. Replace the oxygen sensor if the pigtail wiring, connector, or terminal is damaged. This external clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors, or terminals could result in the obstruction of the air reference and degraded sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: * Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor causing poor performance. * Do not damage the sensor pigtail and harness wires in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. * Ensure the sensor or vehicle lead wires are not bent sharply or kinked. Sharp bends or kinks could block the reference air path through the lead wire. * Do not remove or defeat the oxygen sensor ground wire, where applicable. Vehicles that utilize the ground wired sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will cause poor engine performance. * Ensure that the peripheral seal remains intact on the vehicle harness connector in order to prevent damage due to water intrusion. The engine harness may be repaired using Packard's Crimp and Splice Seals Terminal Repair Kit. Under no circumstances should repairs be soldered since this could result in the air reference being obstructed.

Remove the HO2S and visually inspect the portion of the sensor exposed to the exhaust stream in order to check for contamination. If contaminated, the portion of the sensor exposed to the exhaust stream will have a white powdery coating. Silicon contamination causes a high but false HO2S signal voltage (rich exhaust indication). The control module will then reduce the amount of fuel delivered to the engine, causing a severe driveability problem. Eliminate the source of contamination before replacing the oxygen sensor.

Please discard Corporate Bulletin Number 04-06-04-054A (Section 06 - Engine/Propulsion System). The recent rise and expansion of companies selling non-GM parts and accessories has made it necessary to issue this reminder to dealers regarding GM's policy on the use and installation of these aftermarket components. When a dealer is performing a repair under the New Vehicle Limited Warranty, they are required to use only genuine GM or GM-approved parts and accessories. This applies to all warranty repairs, special policy repairs or any repairs paid for by GM. Parts and accessories advertised as being "the same" as parts manufactured by GM, but not sold through GM, do not qualify for use in warranty repairs, special policy repairs or any repairs paid for by GM. During a warranty repair, if a GM original equipment part is not available through GM Customer Care and Aftersales (GM CC&A;), ACDelco(R) distributors, other GM dealers or approved sources, the dealer is to obtain comparable, non-GM parts and clearly indicate, in detail, on the repair order the circumstances surrounding why non-GM parts were used. The dealer must give customers written notice, prior to the sale or service, that such parts or accessories are not marketed or warranted by General Motors. It should also be noted that dealers modifying new vehicles and installing equipment, parts and accessories obtained from sources not authorized by GM are responsible for complying with the National Traffic and Motor Vehicle Safety Act. Certain non-approved parts or assemblies, installed by the dealer or its agent not authorized by GM, may result in a change to the vehicle's design characteristics and may affect the vehicle's ability to conform to federal law. Dealers must fully understand that non-GM approved parts may not have been validated, tested or certified for use. This puts the dealer at risk for potential liability in the event of a part or vehicle failure. If a GM part failure occurs as the result of the installation or use of a non-GM approved part, the warranty will not be honored. A good example of non-authorized modification of vehicles is the result of an ever increasing supply of aftermarket devices available to the customer, which claim to increase the horsepower and torque of the Duramax(TM) Diesel Engines. These include the addition of, but are not limited to one or more of the following modifications: - Propane injection - Nitrous oxide injection - Additional modules (black boxes) that connect to the vehicle wiring systems - Revised engine calibrations downloaded for the engine control module - Calibration modules which connect to the vehicle diagnostic connector - Modification to the engine turbocharger waste gate Although the installation of these devices, or modification of vehicle components, can increase engine horsepower and torque, they may also negatively affect the engine emissions, reliability and/or durability. In addition, other powertrain components, such as transmissions, universal joints, drive shafts, and front/rear axle components, can be stressed beyond design safety limits by the installation of these devices. General Motors does not support or endorse the use of devices or modifications that, when installed, increase the engine horsepower and torque. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED dealer warranty claim submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM (aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed. Refer to the latest version of Bulletin 09-06-04-026 (V8 Gas Engines) or 06-06-01-007 (Duramax(TM) Diesel Engines) for more information on dealer requirements for calibration verification. These same policies apply as they relate to the use of non-GM accessories. Damage or failure from the use or installation of a non-GM accessory will not be covered under warranty. Failure resulting from the alteration or modification of the vehicle, including the cutting, welding or disconnecting of the vehicle's original equipment parts and components will void the warranty. Additionally, dealers will NOT be reimbursed or compensated by GM in the event of any legal inquiry at either the local, state or federal level that Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Technical Service Bulletins > Engine Controls - Aftermarket Accessory Usage > Page 6734 results from the alteration or modification of a vehicle using non-GM approved parts or accessories. Dealers should be especially cautious of accessory companies that claim the installation of their product will not void the factory warranty. Many times these companies have even given direction on how to quickly disassemble the accessory in an attempt to preclude the manufacturer from finding out that is has been installed. Any suspect repairs should be reviewed by the Fixed Operations Manager (FOM), and in Canada by the Warranty Manager (WM) for appropriate repair direction. If it is decided that a goodwill repair is to be made on the vehicle, even with the installation of such non-GM approved components, the customer is to be made aware of General Motors position on this issue and is to sign the appropriate goodwill documentation required by General Motors. It is imperative for dealers to understand that by installing such devices, they are jeopardizing not only the warranty coverage, but also the performance and reliability of the customer's vehicle.

For Duramax(TM) diesel powered engines, refer to the latest version of Corporate Bulletin Number 08-06-04-006G. Supercede: This bulletin is being revised to add the 2011 model year. Please discard Corporate Bulletin Number 09-06-04-026A (Section 06 - Engine/Propulsion System). General Motors is identifying an increasing number of engine, transmission and catalytic converter part failures that are the result of non-GM (aftermarket) engine and transmission control calibrations being used. When alteration to the GM-released engine or transmission control calibrations occurs, it subjects powertrain and driveline components (engine , transmission, transfer case, driveshaft and rear axle) to stresses that were not tested by General Motors. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED dealer warranty claim submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM (aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed. Warranty coverage is based on the equipment and calibrations that were released on the vehicle at time of sale, or subsequently updated by GM. That's because GM testing and validation matches the calibration to a host of criteria that is essential to assure reliability, durability and emissions performance over the life of the warranty coverage and beyond. Stresses resulting from calibrations different from those tested and released by GM can damage or weaken components, leading to poor performance and or shortened life. Additionally, non-GM (aftermarket) issued engine control modifications often do not meet the same emissions performance standards as GM issued calibrations. Depending on state statutes, individuals who install engine control module calibrations that put the vehicle outside the parameters of emissions certification standards may be subject to fines and/or penalties. This bulletin outlines a procedure to identify the presence of non-GM (aftermarket) calibrations. GM recommends performing this check whenever a hard part failure is seen on internal engine or transmission components, or before an engine assembly or transmission assembly is being replaced under warranty. It is also recommended that the engine calibration verification procedure be performed whenever diagnostics indicate that catalytic converter replacement is indicated. The PQC has a process to confirm the ECM/PCM calibration is GM issued. The PQC will require a picture of the engine calibration verification screen, as outlined in this bulletin, before authorizing any V8 gas powered engine replacement. If a non-GM calibration is found and verification has taken place through GM, the remaining powertrain and driveline warranty will be blocked and notated in GMVIS and the dealership will be notified. This block prevents any UNAUTHORIZED warranty claim submission. 1. Connect the Tech 2(R) to the vehicle. 2. Go to: Diagnostics and build the vehicle. 3. Select: Powertrain. 4.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6752 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6753 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6754 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6755 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6756 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6757 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6758 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6759 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6760 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6761 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1.

Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6825 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 6827 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

OBD II diagnostics monitor the system performance and a diagnostic trouble code (DTC) sets if the system performance degrades.The malfunction indicator lamp (MIL) operation and the DTC storage are dictated by the DTC type. A DTC is ranked as a Type A or Type B if the DTC is emissions related. Type C is a non-emissions related DTC.The ECM is in the engine compartment. The ECM is the control center of the engine controls system. The ECM controls the following components: - The fuel injection system - The ignition system - The emission control systems - The on-board diagnostics - The A/C and fan systems - The throttle actuation control (TAC) system The ECM constantly monitors the information from various sensors and other inputs, and controls the systems that affect the vehicle performance and the emissions. The ECM also performs diagnostic tests on various parts of the system. The ECM can recognize operational problems and alert the driver via the MIL. When the ECM detects a malfunction, the ECM stores a DTC. The condition area is identified by the particular DTC that is set. This aids the technician in making repairs. ECM Function The engine control module (ECM) can supply 5 volts or 12 volts to the various sensors or switches. This is done through pull-up resistors to the regulated power supplies within the ECM. In some cases, even an ordinary shop voltmeter will not give an accurate reading because the resistance is too low. Therefore, a DMM with at least 10 megaohms input impedance is required in order to ensure accurate voltage readings.The ECM controls the output circuits by controlling the ground or the power feed circuit through the transistors or a device called an output driver module. EEPROM The electronically erasable programmable read only memory (EEPROM) is a permanent memory that is physically part of the engine control module (ECM). The EEPROM contains program and calibration information that the ECM needs in order to control the powertrain operation.Special equipment, as well as the correct program and calibration for the vehicle, are required in order to reprogram the ECM. Data Link Connector (DLC) The data link connector (DLC) is a 16-pin connector that provides the technician a means of accessing serial data for aid in the diagnosis. This connector allows the technician to use a scan tool in order to monitor the various serial data parameters, and display the DTC information. The DLC is located inside of the drivers compartment, underneath the dash. Malfunction Indicator Lamp (MIL) The malfunction indicator lamp (MIL) is inside of the instrument panel cluster (IPC). The MIL is controlled by the engine control module (ECM) and illuminates when the ECM detects a condition that affects the vehicle emissions. ECM Service Precautions The engine control module (ECM), by design, can withstand the normal current draws that are associated with the vehicle operations. However, care must be used in order to avoid overloading any of these circuits. When testing for opens or shorts, do not ground or apply voltage to any of the ECM circuits unless the diagnostic procedure instructs you to do so. These circuits should only be tested with a DMM. Emissions Diagnosis For State I/M Programs This OBD II equipped vehicle is designed to diagnose any conditions that could lead to excessive levels of the following emissions: - Hydrocarbons (HC) - Carbon monoxide (CO) - Oxides of nitrogen (NOx) - Evaporative emission (EVAP) system losses Should this vehicles on-board diagnostic system (ECM) detect a condition that could result in excessive emissions, the ECM turns ON the malfunction indicator lamp (MIL) and stores a DTC that is associated with the condition. Aftermarket (Add-On) Electrical And Vacuum Equipment NOTE: Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Page 6849 - Do not attach add-on vacuum operated equipment to this vehicle. The use of add-on vacuum equipment may result in damage to vehicle components or systems. - Connect any add-on electrically operated equipment to the vehicle's electrical system at the battery (power and ground) in order to prevent damage to the vehicle. Aftermarket, add-on, electrical and vacuum equipment is defined as any equipment installed on a vehicle after leaving the factory that connects to the vehicles electrical or vacuum systems. No allowances have been made in the vehicle design for this type of equipment. Add-on electrical equipment, even when installed to these strict guidelines, may still cause the powertrain system to malfunction. This may also include equipment not connected to the vehicle electrical system, such as portable telephones and radios. Therefore, the first step in diagnosing any powertrain condition is to eliminate all of the aftermarket electrical equipment from the vehicle. After this is done, if the problem still exists, the problem may be diagnosed in the normal manner. Electrostatic Discharge (ESD) Damage IMPORTANT: In order to prevent possible electrostatic discharge damage to the engine control module (ECM), DO NOT touch the connector pins on the ECM. The electronic components that are used in the control systems are often designed to carry very low voltage. The electronic components are susceptible to damage caused by electrostatic discharge. Less than 100 volts of static electricity can cause damage to some electronic components. There are several ways for a person to become statically charged. The most common methods of charging are by friction and by induction. An example of charging by friction is a person sliding across a car seat.Charging by induction occurs when a person with well insulated shoes stands near a highly charged object and momentarily touches ground. Charges of the same polarity are drained off leaving the person highly charged with the opposite polarity. Static charges can cause damage, therefore, it is important to use care when handling and testing electronic components. Emissions Control Information Label The underhood Vehicle Emissions Control Information Label contains important emission specifications and setting procedures. In the upper left corner is the exhaust emission information. This identifies the year, the manufacturing division of the engine, the displacement of the engine in liters, the class of the vehicle, and type of fuel metering system. There is also an illustrated emission components and vacuum hose schematic. This label is located in the engine compartment of every General Motors vehicle. If the label has been removed, it can be ordered from GM service parts operations (GMSPO). Underhood Inspection IMPORTANT: This inspection is very important and must be done carefully and thoroughly. Perform a careful underhood inspection when performing any diagnostic procedure or diagnosing the cause of an emission test failure. This can often lead to repairing a condition without further steps. Use the following guidelines when performing an inspection: - Inspect all of the vacuum hoses for correct routing, pinches, cuts, or disconnects. - Inspect any hoses that are difficult to see. - Inspect all of the wires in the engine compartment for the following conditions: Burned or chafed spots - Pinched wires - Contact with sharp edges - Contact with hot exhaust manifolds Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Page 6850 Engine Control Module: Service and Repair ENGINE CONTROL MODULE REPLACEMENT NOTE: - Turn the ignition OFF when installing or removing the control module connectors and disconnecting or reconnecting the power to the control module (battery cable, powertrain control module (PCM)/engine control module (ECM)/transaxle control module (TCM) pigtail, control module fuse, jumper cables, etc.) in order to prevent internal control module damage. - Control module damage may result when the metal case contacts battery voltage. DO NOT contact the control module metal case with battery voltage when servicing a control module, using battery booster cables, or when charging the vehicle battery. - In order to prevent any possible electrostatic discharge damage to the control module, do no touch the connector pins or the soldered components on the circuit board. - Remove any debris from around the control module connector surfaces before servicing the control module. Inspect the control module connector gaskets when diagnosing or replacing the control module. Ensure that the gaskets are installed correctly. The gaskets prevent contaminant intrusion into the control module. - The replacement control module must be programmed. IMPORTANT: - It is necessary to record the remaining engine oil life. If the replacement module is not programed with the remaining engine oil life, the engine oil life will default to 100 percent. If the replacement module is not programmed with the remaining engine oil life, the engine oil will need to be changed at 5000 km (3,000 mi) from the last engine oil change. - It is necessary to record the remaining automatic transmission fluid life. If the replacement module is not programed with the remaining automatic transmission fluid life, the automatic transmission fluid life will default to 100 percent. If the replacement module is not programmed with the remaining automatic transmission fluid life, the automatic transmission fluid will need to be changed at 83000 km (50,000 mi) from the last automatic transmission fluid change. Removal Procedure 1. Using a scan tool, retrieve the percentage of remaining engine oil and the remaining automatic transmission fluid life. Record the remaining engine oil and the remaining automatic transmission fluid life. 2. Slide the engine control module (ECM) retainer rearward, disengaging the retainer from the battery shield. 3.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6876 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6877 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6878 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6879 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6880 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6881 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6882 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6883 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6884 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6885 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible.

Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1. Slide the new terminal into the correct cavity at the back of the connector. 2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire. 3.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6949 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6950 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6951 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6959 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6960 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6988 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6989 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6990 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6992 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6993 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6994 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6995 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6996 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 6997 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7015 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector.

Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7016 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such.

Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7019 3. Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1. Slide the new terminal into the correct cavity at the back of the connector. 2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire. 3.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7061 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7062 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7063 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7071 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7099 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7100 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7101 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7102 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7103 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7104 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7105 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7106 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7107 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7108 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3.

Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7127 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7128 3.

Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7172 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7173 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7174 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7182 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. DIAGNOSTIC FAULT INFORMATION TYPICAL SCAN TOOL DATA CIRCUIT/SYSTEM DESCRIPTION The crankshaft position (CKP) sensor circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, low reference circuit and an output signal circuit. The CKP sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 58-tooth reluctor wheel on the crankshaft. Each tooth on the reluctor wheel is spaced at 60-tooth spacing, with 2 missing teeth for the reference gap. The CKP sensor produces an ON/OFF DC voltage of varying frequency, with 58 output pulses per crankshaft revolution. The frequency of the CKP sensor output depends on the velocity of the crankshaft. The CKP sensor sends a digital signal, which represents an image of the crankshaft reluctor wheel, to the ECM as each tooth on the wheel rotates past the CKP sensor. The ECM uses each CKP signal pulse to determine crankshaft speed and decodes the crankshaft reluctor wheel reference gap to identify crankshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses CKP sensor output information to determine the camshaft relative position to the crankshaft, to control camshaft phasing, and to detect cylinder misfire. DIAGNOSTIC AIDS - Inspect the CKP sensor connector and the ECM connector for corrosion. - With a DTC set, the engine may crank for an extended period of time at start-up. CIRCUIT/SYSTEM VERIFICATION If DTC P0641 or P0651 are set diagnose those DTCs first. 1. With the ignition OFF, inspect the engine wiring harnesses carrying the CKP sensor circuits for the following conditions: - Close routing of secondary ignition wires - Close routing of aftermarket electrical equipment - Close to solenoids, motors, and relays - Correct any wire harness routing or component placement conditions, if it is determined to be a possible source of electrical interference. 2. Start the engine. Using the Live Plot function on the scan tool, select the CMP parameter. Change the minimum spec to 400 RPM, and the maximum spec to 4,000 RPM. Select the CKP sensor parameter. Change the minimum spec to 600 RPM, and the maximum spec to 3,300 RPM. 3. Observe the scan tool. 4. Quickly accelerate and release the accelerator pedal several time. Do not exceed 3,200 RPM. The graphed lines on the Live Plot display should track together across the screen. If the vehicle passes the Circuit/System Verification test, operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records data list.

Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7227 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7228 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7229 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7230 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7231 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7232 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7233 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7234 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7235 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7236 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7300 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7301 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7302 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

IMPORTANT: You must perform the following procedures in the order listed. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip keeping all of the wire strands intact. Open the harness by removing any tape. 2. Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. 3. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 4. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent american wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 5. Slide a section of high temperature SCT1 shrink tubing down the length of wire to be spliced. Ensure that the shrink tubing will not interfere with the splice procedure. 6. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 7. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 8. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 9. Insert the wire into the DuraSeal splice sleeve barrel until the wire hits the barrel stop. 10. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7348 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7349 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7350 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7351 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7352 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7353 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7354 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7355 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7356 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7357 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7421 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7422 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7423 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing.

Remove the HO2S and visually inspect the portion of the sensor exposed to the exhaust stream in order to check for contamination. If contaminated, the portion of the sensor exposed to the exhaust stream will have a white powdery coating. Silicon contamination causes a high but false HO2S signal voltage (rich exhaust indication). The control module will then reduce the amount of fuel delivered to the engine, causing a severe driveability problem. Eliminate the source of contamination before replacing the oxygen sensor.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7461 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7462 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7463 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7464 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7465 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7466 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7467 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7468 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7469 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7470 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7534 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7535 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7536 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7576 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7577 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7578 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7579 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7580 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7581 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7582 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7583 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7584 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7585 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7604 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7649 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7650 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7651 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Please discard Corporate Bulletin Number 06-06-01-010 (Section 06 - Engine/Propulsion System). Certain 2004-2008 General Motors products may be equipped with a new style of catalytic converter technically known as the close-coupled catalytic converter providing quick catalyst warm-up resulting in lower tail pipe emissions earlier in the vehicle operating cycle. If an engine breakdown or non-function were to occur (such as broken intake/exhaust valve or piston) debris may be deposited in the converter through engine exhaust ports. If the engine is non-functioning due to a severe overheat event damage to the ceramic "brick" internal to the catalytic converter may occur. This may result in ceramic debris being drawn into the engine through the cylinder head exhaust ports. If a replacement engine is installed in either of these instances the replacement engine may fail due to the debris being introduced into the combustion chambers when started. When replacing an engine for a breakdown or non-function an inspection of the catalytic converters and ALL transferred components (such as exhaust/ intake manifolds) should be performed. Any debris found should be removed. In cases of engine failure due to severe overheat dealers should also inspect each catalytic converter for signs of melting or cracking of the ceramic "brick". If damage is observed the converter should be replaced.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. CIRCUIT/SYSTEM DESCRIPTION The control module enables the fuel pump relay when the ignition switch is turned ON. The control module will disable the fuel pump relay within 2 seconds unless the control module detects ignition reference pulses. The control module continues to enable the fuel pump relay as long as ignition reference pulses are detected. The control module disables the fuel pump relay within 2 seconds if ignition reference pulses cease to be detected and the ignition remains ON.The fuel system is a returnless on-demand design. The fuel pressure regulator is a part of the primary fuel tank module, eliminating the need for a return pipe from the engine. A returnless fuel system reduces the internal temperature of the fuel tank by not returning hot fuel from the engine to the fuel tank. Reducing the internal temperature of the fuel tank results in lower evaporative emissions. An electric turbine style fuel pump attaches to the primary fuel tank module inside the fuel tank. The fuel pump supplies high pressure fuel through the fuel filter, past the fuel pressure regulator, and through the fuel feed pipe to the fuel injection system. The fuel pressure regulator has a T-joint that diverts the needed fuel to the fuel rail with the unused fuel dropping back into the reservoir of the primary fuel tank module. The primary fuel tank module contains a reverse flow check valve. The check valve and the fuel pressure regulator maintain fuel pressure in the fuel feed pipe and the fuel rail in order to prevent long cranking times. The primary fuel tank module also contains a primary jet pump and a secondary jet pump. Fuel pump flow loss, caused by vapor expulsion in the pump inlet chamber, is diverted to the primary jet pump and the secondary jet pump through a restrictive orifice located on the pump cover. The primary jet pump fills the reservoir of the primary fuel tank module. The secondary jet pump creates a venturi action which causes the fuel to be drawn from the secondary side of the fuel tank, through the fuel transfer pipe, to the primary side of the fuel tank. CIRCUIT/SYSTEM VERIFICATION IMPORTANT: Inspect the fuel system for damage or external leaks before proceeding. - Verify that adequate fuel is in the fuel tank before proceeding. - The fuel pump relay may need to be commanded ON a few times in order to obtain the highest possible fuel pressure. - Before proceeding with this test review the User Manual CH 48027-5 for Safety Information and Instructions. 1. Ignition ON, engine OFF, command the fuel pump relay ON with a scan tool. You should hear the fuel pump turn ON and OFF. - If the fuel pump does not operate, refer to Fuel Pump Electrical Circuit Diagnosis. See: Computers and Control Systems/Testing and Inspection/Component Tests and General Diagnostics 2. Ignition OFF, all accessories OFF, install a CH-48027. 3. Ignition ON, engine OFF, command the fuel pump relay ON with a scan tool. Verify the fuel pressure is between 384-425 kPa (56-62 psi) and does not decrease more than 34 kPa (5 psi) in 1 minute.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7792 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7793 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7794 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7795 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7796 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7797 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7798 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7799 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7800 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7801 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7819 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7820 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7865 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7866 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7867 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

Only the connector body is available for connectors with more than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the connector body. SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7872 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 7875 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10.

GM believes that the waiver decision by the EPA regarding E 15 could lead to confusion for consumers as to what fuel their vehicle should use. In response, we will continue to encourage our customers to refer to their vehicle Owner Manual for proper fuel designation. The vehicle Owner Manual specifies that fuels containing more than 10 percent ethanol should not be used in GM vehicles that do not have a flex fuel designation. - GM has the largest fleet of flex fuel vehicles on the road today (over 4 million in the U.S.) and these vehicles can safely use ethanol blends of up to 85 percent ethanol. So blends of E 15 (15 percent ethanol), as in the partial waiver announced, are appropriate for these vehicles. However, ethanol blends greater than E 10 should not be used in GM vehicles that do not have a flex fuel designation as they are not designed and certified to run on gasoline consisting of more than 10 percent ethanol-blend volume to avoid any unintended consequences, as per: their Owner Manual. - We believe biofuels, especially E 85 ethanol, are an effective near-term solution to reduce petroleum dependence and the carbon footprint of driving. As the global leader in producing vehicles designed to handle ethanol blends from E 0 to E 85, GM offers 19 flexible-fuel vehicles for the 2011 model year.

Where Can TOP TIER Detergent Gasoline Be Purchased? The TOP TIER program began in the U.S. and Canada on May 3, 2004. Some fuel marketers have already joined and introduced TOP TIER Detergent Gasoline. This is a voluntary program and not all fuel marketers will offer this product. Once fuel marketers make public announcements, they will appear on a list of brands that meet the TOP TIER standards. Who developed TOP TIER Detergent Gasoline standards? TOP TIER Detergent Gasoline standards were developed by six automotive companies: BMW, General Motors, Honda, Toyota, Volkswagen and Audi. Why was TOP TIER Detergent Gasoline developed? TOP TIER Detergent Gasoline was developed to increase the level of detergent additive in gasoline. In the U.S., government regulations require that all gasoline sold in the U.S. contain a detergent additive. However, the requirement is minimal and in many cases, is not sufficient to keep engines clean. In Canada, gasoline standards recommend adherence to U.S. detergency requirements but do not require it. In fact, many brands of gasoline in Canada do not contain any detergent additive. In order to meet TOP TIER Detergent Gasoline standards, a higher level of detergent is needed than what is required or recommended, and no metallic additives are allowed. Also, TOP TIER was developed to give fuel marketers the opportunity to differentiate their product. Why did the six automotive companies join together to develop TOP TIER? All six corporations recognized the benefits to both the vehicle and the consumer. Also, joining together emphasized that low detergency and the intentional addition of metallic additives is an issue of concern to several automotive companies. What are the benefits of TOP TIER Detergent Gasoline? TOP TIER Detergent Gasoline will help keep engines cleaner than gasoline containing the "Lowest Additive Concentration" recommended by Canadian standards. Clean engines help provide optimal fuel economy and engine performance, and also provide reduced emissions. Also, the use of TOP TIER Detergent Gasoline will help reduce deposit related concerns. Who should use TOP TIER Detergent Gasoline? All vehicles will benefit from using TOP TIER Detergent Gasoline over gasoline containing the "Lowest Additive Concentration" recommended by Canadian standards.

Please discard Corporate Bulletin Number 05-06-04-035B (Section 06 Engine/Propulsion System). Customer Interest in E85 Fuel As the retail price of gasoline increases, some locations in the country are seeing price differentials between regular gasoline and E85 where E85 is selling for substantially less than regular grade gasoline. One result of this is that some customers have inquired if they are able to use E85 fuel in non-E85 compatible vehicles. Only vehicles designated for use with E85 should use E85 blended fuel. E85 compatibility is designated for vehicles that are certified to run on up to 85% ethanol and 15% gasoline. All other gasoline engines are designed to run on fuel that contains no more than 10% ethanol. Use of fuel containing greater than 10% ethanol in non-E85 designated vehicles can cause driveability issues, service engine soon indicators as well as increased fuel system corrosion. Using E85 Fuels in Non-Compatible Vehicles General Motors is aware of an increased number of cases where customers have fueled non-FlexFuel designated vehicles with E85. Fueling non-FlexFuel designated vehicles with E85, or with fuels where the concentration of ethanol exceeds the ASTM specification of 10%, will result in one or more of the following conditions: Lean Driveability concerns such as hesitations, sags and/or possible stalling. SES lights due to OBD codes. Fuel Trim codes P0171 and/or P0174. Misfire codes (P0300). Various 02 sensor codes. Disabled traction control or Stability System disabled messages. Harsh/Firm transmission shifts. Fuel system and/or engine mechanical component degradation. Use of fuel containing greater than 10% ethanol in non-E85 designated vehicles can cause driveability issues, service engine soon indicators as well as increased fuel system corrosion. If the dealer suspects that a non-FlexFuel designated vehicle brought in for service has been fueled with E85, the fuel in the vehicle's tank should be checked for alcohol content with tool J 44175. If the alcohol content exceeds 10% the fuel should be drained and the vehicle refilled with gasoline - preferably one of the Top Tier brands.

Customer Questions, Concerns and Refueling Locations for E85 Fuel Extensive information on E85 Ethanol based fuels can be found at www.livegreengoyellow.com . This General Motors site contains vital information that anticipates and answers customer questions and concerns about E85 fuel. Part of the information is a useful link that provides the location nationally of all E85 refueling stations. Disclaimer Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel > Component Information > Technical Service Bulletins > Page 7895 Fuel: Specifications GASOLINE OCTANE Use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, you may notice an audible knocking noise when you drive, commonly referred to as spark knock. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, your engine needs service. GASOLINE SPECIFICATIONS At a minimum, gasoline should meet ASTM specification D 4814 in the United States or CAN/CGSB-3.5 in Canada. Some gasolines may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). General Motors recommends against the use of gasolines containing MMT. CALIFORNIA FUEL If your vehicle is certified to meet California Emission Standards, it is designed to operate on fuels that meet California specifications. See the underhood emission control label. If this fuel is not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp may turn on and your vehicle may fail a smog-check test. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by your warranty. ADDITIVES To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. In most cases, you should not have to add anything to your fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. To help keep fuel injectors and intake valves clean, or if your vehicle experiences problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline. Also, your dealer has additives that will help correct and prevent most deposit-related problems. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area. General Motors recommends that you use these gasolines if they comply with the specifications described earlier. However, E85 (85% ethanol) and other fuels containing more than 10% ethanol must not be used in vehicles that were not designed for those fuels. NOTICE: Your vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under your warranty. Some gasolines that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. General Motors recommends against the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The malfunction indicator lamp may turn on. If this occurs, return to your dealer for service. NOTICE: Your vehicle was not designed for fuel that contains methanol.

The malfunction indicator lamp may turn on. FUELS IN FOREIGN COUNTRIES If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel would not be covered by your warranty. To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving.

A fire could occur if an ignition source is present. Never drain or store gasoline or diesel fuel in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher nearby. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel > Component Information > Technical Service Bulletins > Page 7897 Fuel: Testing and Inspection ALCOHOL/CONTAMINANTS-IN-FUEL DIAGNOSIS TEST DESCRIPTION Water contamination in the fuel system may cause driveability conditions such as hesitation, stalling, no start, or misfires in one or more cylinders. Water may collect near a single fuel injector at the lowest point in the fuel injection system and cause a misfire in that cylinder. If the fuel system is contaminated with water, inspect the fuel system components for rust or deterioration. Ethanol concentrations of greater than 10 percent can cause driveability conditions and fuel system deterioration. Fuel with more than 10 percent ethanol could result in driveability conditions such as hesitation, lack of power, stalling, or no start. Excessive concentrations of ethanol used in vehicles not designed for it may cause fuel system corrosion, deterioration of rubber components, and fuel filter restriction. SYSTEM VERIFICATION The fuel sample should be drawn from the bottom of the tank so that any water present in the tank will be detected. The sample should be bright and clear. If the sample appears cloudy, or contaminated with water, as indicated by a water layer at the bottom of the sample, perform the Particulate Contaminants in Fuel Testing Procedure. - If alcohol contamination is suspected, perform the Alcohol in Fuel Testing procedure. ALCOHOL IN FUEL TESTING WITH SPECIAL TOOL 1. Test the fuel composition using J 44175 and Instruction Manual. 2. If water appears in the fuel sample, clean the fuel system. 3. Subtract 50 from the reading on the DMM in order to obtain the percentage of alcohol in the fuel sample. 4. If the fuel sample contains more than 15 percent ethanol, add fresh, regular gasoline to the vehicle fuel tank. 5. Test the fuel composition. 6. If testing shows the ethanol percentage is still more than 15 percent, replace the fuel in the vehicle. ALCOHOL IN FUEL TESTING WITHOUT SPECIAL TOOL 1. Using a 100 ml (3.38 oz) specified cylinder with 1 ml (0.034 oz) graduation marks, fill the cylinder with fuel to the 90 ml (3.04 oz) mark. 2. Add 10 ml (0.34 oz) of water in order to bring the total fluid volume to 100 ml (3.38 oz) and install a stopper. 3. Shake the cylinder vigorously for 10-15 seconds. 4. Carefully loosen the stopper in order to release the pressure. 5. Re-install the stopper and shake the cylinder vigorously again for 10-15 seconds. 6. Put the cylinder on a level surface for approximately 5 minutes in order to allow adequate liquid separation. If alcohol is present in the fuel, the volume of the lower layer, which would now contain both alcohol and water, will be more than 10 ml (0.34 oz). For example, if the volume of the lower layer is increased to 15 ml (0.51 oz), this indicates at least 5 percent alcohol in the fuel. The actual amount of alcohol may be somewhat more because this procedure does not extract all of the alcohol from the fuel. PARTICULATE CONTAMINANTS IN FUEL TESTING PROCEDURE 1. Using an approved fuel container, draw approximately 0.5 liter (0.53 qt) of fuel. 2. Place the container on a level surface for approximately 5 minutes in order to allow settling of the particulate contamination. Particulate contamination will show up in various shapes and colors. Sand will typically be identified by a white or light brown crystals. Rubber will appear as black and irregular particles. 3. Observe the fuel sample. If any physical contaminants or water are present, clean the fuel system. REPAIR INSTRUCTIONS Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

Please discard Corporate Bulletin Number 03-06-04-030F (Section 06 - Engine/Propulsion System). Condition Some customers may comment on any of the following various driveability symptoms: - Extended Crank Time - Hard to Start - MIL/SES Illuminated with DTCs - Hesitation - Lack of Power - Surge or Chuggle - Rough Idle - Light or Intermittent Misfire Cause Due to various factors, the fuel injectors may become restricted. Extensive testing has demonstrated that fuel related issues are the cause of clogged injectors. At this point, no specific fuel, fuel constituent, or engine condition has been identified as causing the restriction. The restriction causes the engine to operate at a lean air fuel ratio. This may either trigger the MIL to illuminate or the engine to develop various driveability symptoms.

Under NO circumstances should this procedure be modified, changed or shortened. As a long term solution, and to prevent reoccurrence, customers should be encouraged to use Top Tier Detergent Gasoline. For further information on Top Tier detergent gasoline and fuel retailers, please refer to the following Corporate Bulletin Numbers: - 04-06-04-047G (U.S. Only) - 05-06-04-022D (Canada ONLY) Notice GM UPPER ENGINE AND FUEL INJECTOR CLEANER is the only injector cleaning agent approved for use with General Motors fuel system components. Other injector cleaners may cause damage to plastics, plated metals or bearings. General Motors has completed extensive laboratory testing of GM Upper Engine and Fuel Injector Cleaner, and can assure its compatibility with General Motors fuel system components, as long as the cleaning procedure is followed correctly. Injector Cleaning Procedure The following tools, or their equivalent, are required: - CH-47976 Active Fuel Injector Tester (AFIT) - J 35800-A Fuel Injector Cleaner - J 37287 Fuel Line Shut-off Adapter - J 42964 Fuel Line Shut-off Adapter - J 42873 Fuel Line Shut-off Adapter - * One bottle of GM Upper Engine and Fuel Injector Cleaner, P/N 88861802 (in Canada, P/N 88861804) - * One bottle of GM Fuel System Treatment Plus, P/N 88861011 (in Canada, P/N 88861012) Active Fuel Injector Tester (AFIT- CH-47976) Some dealers may not have an Active Fuel Injector Tester (AFIT- CH-47976). Dealers can contact to order an AFIT- CH-47976. Dealers still can test the fuel injectors without an AFIT. Refer to Fuel Injector Diagnosis (w/ J 39021 or Tech 2(R)) in SI. Important As mentioned in the AFIT User Guide, vehicles that are not listed in the AFIT menu can still be tested with the AFIT. Depending on the model, it may be possible to enter the previous model year and proceed with testing using the DLC connection. If this is not possible on the model that you are working on, it will be necessary to use the direct connection method outlined in the AFIT User Guide (See Pages 17-31). General Motors recommends that the Active Fuel Injector Tester (AFIT) be used in testing fuel injectors. If the SI diagnostics do not isolate a cause for this concern, use the Active Fuel Injector Tester (AFIT - CH-47976) to perform an "Injector Test" as outlined in the AFIT User Guide. The AFIT "Injector Test" measures the flow characteristics of all fuel injectors, which is more precise when compared with the standard Tech 2(R) fuel injector balance test. As a result, the AFIT is more likely to isolate the cause of a P1174 DTC (for example: if it is being caused by a fuel injector concern). The CH-47976 (Active Fuel Injector Tester - AFIT) can also be used to measure fuel pressure and fuel system leak down. Also, as mentioned in the P1174 SI diagnosis, if the misfire current counters or misfire graph indicate any misfires, it may be an indicator of the cylinder that is causing the concern. Refer to Fuel Injector Diagnosis (w/CH-47976) in SI for additional instructions. Training (U.S.) To access the training video on AFIT, take the following path at the GM Training Website: 1.

Injector Cleaning Procedure Notice GM UPPER ENGINE AND FUEL INJECTOR CLEANER is the only injector cleaning agent recommended. DO NOT USE OTHER CLEANING AGENTS AS THEY MAY CONTAIN METHANOL, WHICH CAN DAMAGE FUEL SYSTEM COMPONENTS. Under NO circumstances should the GM Upper Engine and Fuel Injector Cleaner be added to the vehicle fuel tank. Do not exceed the recommended cleaning solution concentration. Testing has demonstrated that exceeding the recommended cleaning solution concentration does not improve the effectiveness of this procedure. Important Vehicles with less than 160 km (100 mi) on the odometer should not have the injectors cleaned. These vehicles should have any out of specification injectors replaced. 1. For 4, 5 and 6 cylinder engines, empty two of the 30 ml (1 oz) reservoirs of the GM Upper Engine and Fuel Injector Cleaner container into the J 35800-A - Injector Cleaning Tank then add 420 ml (14 oz) of regular unleaded gasoline.

Please discard Corporate Bulletin Number 03-06-04-030F (Section 06 - Engine/Propulsion System). Condition Some customers may comment on any of the following various driveability symptoms: - Extended Crank Time - Hard to Start - MIL/SES Illuminated with DTCs - Hesitation - Lack of Power - Surge or Chuggle - Rough Idle - Light or Intermittent Misfire Cause Due to various factors, the fuel injectors may become restricted. Extensive testing has demonstrated that fuel related issues are the cause of clogged injectors. At this point, no specific fuel, fuel constituent, or engine condition has been identified as causing the restriction. The restriction causes the engine to operate at a lean air fuel ratio. This may either trigger the MIL to illuminate or the engine to develop various driveability symptoms.

Other injector cleaners may cause damage to plastics, plated metals or bearings. General Motors has completed extensive laboratory testing of GM Upper Engine and Fuel Injector Cleaner, and can assure its compatibility with General Motors fuel system components, as long as the cleaning procedure is followed correctly. Injector Cleaning Procedure The following tools, or their equivalent, are required: - CH-47976 Active Fuel Injector Tester (AFIT) - J 35800-A Fuel Injector Cleaner - J 37287 Fuel Line Shut-off Adapter - J 42964 Fuel Line Shut-off Adapter - J 42873 Fuel Line Shut-off Adapter - * One bottle of GM Upper Engine and Fuel Injector Cleaner, P/N 88861802 (in Canada, P/N 88861804) - * One bottle of GM Fuel System Treatment Plus, P/N 88861011 (in Canada, P/N 88861012) Active Fuel Injector Tester (AFIT- CH-47976) Some dealers may not have an Active Fuel Injector Tester (AFIT- CH-47976). Dealers can contact to order an AFIT- CH-47976. Dealers still can test the fuel injectors without an AFIT. Refer to Fuel Injector Diagnosis (w/ J 39021 or Tech 2(R)) in SI. Important As mentioned in the AFIT User Guide, vehicles that are not listed in the AFIT menu can still be tested with the AFIT. Depending on the model, it may be possible to enter the previous model year and proceed with testing using the DLC connection. If this is not possible on the model that you are working on, it will be necessary to use the direct connection method outlined in the AFIT User Guide (See Pages 17-31). General Motors recommends that the Active Fuel Injector Tester (AFIT) be used in testing fuel injectors. If the SI diagnostics do not isolate a cause for this concern, use the Active Fuel Injector Tester (AFIT - CH-47976) to perform an "Injector Test" as outlined in the AFIT User Guide. The AFIT "Injector Test" measures the flow characteristics of all fuel injectors, which is more precise when compared with the standard Tech 2(R) fuel injector balance test. As a result, the AFIT is more likely to isolate the cause of a P1174 DTC (for example: if it is being caused by a fuel injector concern). The CH-47976 (Active Fuel Injector Tester - AFIT) can also be used to measure fuel pressure and fuel system leak down. Also, as mentioned in the P1174 SI diagnosis, if the misfire current counters or misfire graph indicate any misfires, it may be an indicator of the cylinder that is causing the concern. Refer to Fuel Injector Diagnosis (w/CH-47976) in SI for additional instructions. Training (U.S.) To access the training video on AFIT, take the following path at the GM Training Website: 1.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7947 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7948 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7949 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7950 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7951 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7952 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7953 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7954 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7955 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7956 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7974 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 7975 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 8020 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 8021 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 8022 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 8027 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 8029 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Diagrams > Diagram Information and Instructions > Page 8030 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. CIRCUIT/SYSTEM DESCRIPTION The control module enables the appropriate fuel injector pulse for each cylinder. The ignition voltage is supplied directly to the fuel injectors. The control module controls each fuel injector by grounding the control circuit via a solid state device called a driver. A fuel injector coil winding resistance that is too high or too low will affect the engine driveability. A fuel injector control circuit DTC may not set, but a misfire may be apparent. The fuel injector coil windings are affected by temperature. The resistance of the fuel injector coil windings will increase as the temperature of the fuel injector increases. When performing the fuel injector balance test, the scan tool is first used to energize the fuel pump relay. The fuel injector tester or the scan tool is then used to pulse each injector for a precise amount of time, allowing a measured amount of the fuel to be injected. This causes a drop in the system fuel pressure that can be recorded and used to compare each injector. DIAGNOSTIC AIDS - Monitoring the misfire current counters, or misfire graph, may help to isolate the fuel injector that is causing the condition. - Operating the vehicle over a wide temperature range may help isolate the fuel injector that is causing the condition. - Perform the fuel injector coil test within the conditions of the customer's concern. A fuel injector condition may only be apparent at a certain temperature, or under certain conditions. COMPONENT TESTING Fuel Injector Coil Test 1. Observe the ECT Sensor parameter with a scan tool. The ECT sensor should be 10-32°C (50-90°F). - If the ECT Sensor parameter is not within 10-32°C (50-90°F), go to step 3. 2. Measure the resistance of each fuel injector with a DMM. The resistance of each fuel injector should be 11-14 ohms. - If the resistance of any fuel injector is not 11-14 ohms, replace the fuel injector. 3. Measure and record the resistance of each fuel injector with a DMM. Subtract the lowest resistance value from the highest resistance value. The difference between the lowest value and the highest value should be equal to or less than 3 ohms. If the difference is equal to or less than 3 ohms, perform the Fuel Injector Balance Test-Fuel Pressure Test. - If the difference is more than 3 ohms, continue with the Fuel Injector Coil Test. 4. Add all of the fuel injector resistance values to obtain a total resistance value. Divide the total resistance value by the number of fuel injectors to obtain an average resistance value. Subtract the lowest individual fuel injector resistance value from the average resistance value. Compute the difference between the highest individual fuel injector resistance value and the average resistance value. Replace the fuel injector that displays the greatest resistance difference above or below the average. 5. Perform the Fuel Injector Balance Test-Fuel Pressure Test. IMPORTANT: DO NOT perform this test if the engine coolant temperature (ECT) is above 94°C (201°F). Irregular fuel pressure readings may result due to hot soak fuel boiling. - Verify that adequate fuel is in the fuel tank before proceeding with this diagnostic. - Before proceeding with this test review the User Manual CH 48027-5 for Safety Information and Instructions. Fuel Injector Balance Test-Fuel Pressure Test 1. Install a fuel pressure gage. 2. Turn ON the ignition, with the engine OFF. 3. IMPORTANT: - The fuel pump relay may need to be commanded ON a few times in order to obtain the highest possible fuel pressure. - DO NOT start the engine. Command the fuel pump relay ON with a scan tool. 4. Observe the fuel pressure gage with the fuel pump commanded ON. The fuel pressure should be 384-425 kPa (56-62 psi). - If the fuel pressure is not 384-425 kPa (56-62 psi), refer to Fuel System Diagnosis. See: Computers and Control Systems/Testing and Inspection/Component Tests and General Diagnostics 5. Monitor the fuel pressure gage for one minute. The fuel pressure should not decrease more than 34 kPa (5 psi). - If the fuel pressure decreases more than 34 kPa (5 psi), refer to Fuel System Diagnosis. See: Computers and Control Systems/Testing and Inspection/Component Tests and General Diagnostics 6. Perform the Fuel Injector Balance Test with Special Tool or the Fuel Injector Balance Test with Tech 2.

Connect the J 39021, the J 39021-210, and the J 39021-410 to the fuel injector multi-way connector. 4. Command the fuel pump relay ON and then OFF three times with a scan tool. On the last command, as the fuel pressure begins to slowly degrade and stabilize, select a fuel pressure within 34 kPa (5 psi) of the maximum pump pressure. Record this fuel pressure. This is the starting pressure at which you will pulse each injector. 5. Command the fuel pump relay ON one more time and energize the fuel injector by depressing the Push to Start Test button on the J 39021 at the previously selected pressure. 6. After the injector stops pulsing, select Min from the Display Mode and record the Min pressure. 7. IMPORTANT: New test results will not be recorded if the Min/Max results are not cleared after each injector is tested. Clear the Min/Max results. 8. Select Normal from the Display Mode. 9. Repeat steps 3 and 5 through 8 for each fuel injector. 10. Perform the Pressure Drop Calculation. Fuel Injector Balance Test With Tech 2 1. IMPORTANT: Vehicle's with thief immobilizer disable the test. Command the fuel pump relay ON and then OFF three times with a scan tool. On the last command, as the fuel pressure begins to slowly degrade and stabilize, select a fuel pressure within 34 kPa (5 psi) of the maximum pump pressure. Record this fuel pressure. This is the starting pressure at which you will pulse each injector. 2. With a scan tool, select the Fuel Injector Balance Test function within the Special Functions menu. 3. Select an injector to be tested. 4. Press Enter to prime the fuel system. 5. Energize the fuel injector by depressing the Pulse Injector button on the scan tool at the previously selected pressure. 6. After the injector stops pulsing, select Min from the Display Mode on the CH-48027 and record the Min pressure. 7. IMPORTANT: New test results will not be recorded if the Min/Max results are not cleared after each injector is tested. Clear the Min/Max results on the CH-48027. 8. Select Normal from the Display Mode on the CH-48027. 9. Press Enter on the scan tool to bring you back to the Select Injector screen. 10. Repeat steps 3 through 9 for each fuel injector. 11. Perform the Pressure Drop Calculation. Pressure Drop Calculation 1. Subtract the minimum pressure from the starting pressure for one fuel injector. The result is the pressure drop value. 2. Obtain a pressure drop value for each fuel injector. 3. Add all of the individual pressure drop values except for the injector suspected of being faulty. This is the total pressure drop. 4. Divide the total pressure drop by the number of fuel injectors that were added together. This is the average pressure drop. The difference between any individual pressure drop and the average pressure drop should not be more than 20 kPa (3 psi). - If the difference between any individual pressure drop and the average pressure drop is more than 20 kPa (3 psi), replace the fuel injector.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. CIRCUIT/SYSTEM DESCRIPTION The control module enables the fuel pump relay when the ignition switch is turned ON. The control module will disable the fuel pump relay within 2 seconds unless the control module detects ignition reference pulses. The control module continues to enable the fuel pump relay as long as ignition reference pulses are detected. The control module disables the fuel pump relay within 2 seconds if ignition reference pulses cease to be detected and the ignition remains ON.The fuel system is a returnless on-demand design. The fuel pressure regulator is a part of the primary fuel tank module, eliminating the need for a return pipe from the engine. A returnless fuel system reduces the internal temperature of the fuel tank by not returning hot fuel from the engine to the fuel tank. Reducing the internal temperature of the fuel tank results in lower evaporative emissions. An electric turbine style fuel pump attaches to the primary fuel tank module inside the fuel tank. The fuel pump supplies high pressure fuel through the fuel filter, past the fuel pressure regulator, and through the fuel feed pipe to the fuel injection system. The fuel pressure regulator has a T-joint that diverts the needed fuel to the fuel rail with the unused fuel dropping back into the reservoir of the primary fuel tank module. The primary fuel tank module contains a reverse flow check valve. The check valve and the fuel pressure regulator maintain fuel pressure in the fuel feed pipe and the fuel rail in order to prevent long cranking times. The primary fuel tank module also contains a primary jet pump and a secondary jet pump. Fuel pump flow loss, caused by vapor expulsion in the pump inlet chamber, is diverted to the primary jet pump and the secondary jet pump through a restrictive orifice located on the pump cover. The primary jet pump fills the reservoir of the primary fuel tank module. The secondary jet pump creates a venturi action which causes the fuel to be drawn from the secondary side of the fuel tank, through the fuel transfer pipe, to the primary side of the fuel tank. CIRCUIT/SYSTEM VERIFICATION IMPORTANT: Inspect the fuel system for damage or external leaks before proceeding. - Verify that adequate fuel is in the fuel tank before proceeding. - The fuel pump relay may need to be commanded ON a few times in order to obtain the highest possible fuel pressure. - Before proceeding with this test review the User Manual CH 48027-5 for Safety Information and Instructions. 1. Ignition ON, engine OFF, command the fuel pump relay ON with a scan tool.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8078 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8079 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8080 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8081 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8082 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8083 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8084 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8085 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8086 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8087 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3.

Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8106 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8107 3.

Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8109 3. Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8151 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8152 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8153 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8160 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8161 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8162 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

Upon further investigation, the technician may find DTC P0442 (EVAP small leak) or P0455 (EVAP large leak) set as current or in history. Cause This condition may be caused by the rubber grommet at the fuel tank filler neck not being properly seated. In some situations, the inner lip of the grommet may ride over the top of the filler neck, preventing the fuel cap from tightening properly, resulting in poor sealing. This can set the small or large leak diagnostic codes. Correction DO NOT replace the fuel cap for this condition. Follow the instructions listed below. 1. Inspect the rubber grommet for damage. Replace if necessary. 2. Ensure that the grommet is correctly seated to the fuel filler neck pocket. 3. If the grommet is not correctly seated, use a non-metallic tool to push down on the inner lip of the grommet, folding it inward on the fill pipe. This will prevent the possibility of the inner lip interfering with the fuel cap.

Upon further investigation, the technician may find DTC P0442 (EVAP small leak) or P0455 (EVAP large leak) set as current or in history. Cause This condition may be caused by the rubber grommet at the fuel tank filler neck not being properly seated. In some situations, the inner lip of the grommet may ride over the top of the filler neck, preventing the fuel cap from tightening properly, resulting in poor sealing. This can set the small or large leak diagnostic codes. Correction DO NOT replace the fuel cap for this condition. Follow the instructions listed below. 1. Inspect the rubber grommet for damage. Replace if necessary. 2. Ensure that the grommet is correctly seated to the fuel filler neck pocket. 3. If the grommet is not correctly seated, use a non-metallic tool to push down on the inner lip of the grommet, folding it inward on the fill pipe. This will prevent the possibility of the inner lip interfering with the fuel cap.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8252 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8253 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8254 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8256 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8257 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8258 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8259 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8260 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8261 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1.

Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8280 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Relays and Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions > Page 8325 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8362 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8363 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8364 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8366 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8367 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8368 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8369 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8370 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8371 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8435 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Air Flow Meter/Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8436 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests.

Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8468 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8469 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8470 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8472 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8473 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8474 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8475 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8476 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8477 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible.

Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8541 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8542 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8548 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape.

Anytime the throttle body is cleaned or replaced, the ECM must learn the new throttle position. The idle may be unstable or a DTC may set if the throttle position is not learned. CONDITIONS FOR RUNNING THE THROTTLE LEARN PROCEDURE - DTCs P0101, P0102, P0103, P0107, P0108, P0111, P0112, P0113, P0506, and P0507 are not set. - The engine speed is between 450-4,000 RPM. - The manifold absolute pressure (MAP) is greater than 5 kPa. - The mass air flow (MAF) is greater than 2 g/s. - The ignition 1 voltage is greater than 10 volts. THROTTLE LEARN IMPORTANT: Do NOT perform this procedure if DTCs are set. Refer to Diagnostic Trouble Code (DTC) List - Vehicle. See: Computers and Control Systems/Testing and Inspection/Diagnostic Trouble Code Descriptions 1. Start and idle the engine in PARK for 3 minutes. 2. With a scan tool, monitor desired and actual RPM. 3. The ECM will start to learn the new idle cells and Desired RPM should start to decrease. 4. Ignition OFF for 60 seconds. 5. Start and idle the engine in PARK for 3 minutes. 6. After the 3 minute run time the engine should be idling normal. - IMPORTANT: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn. If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles. 7. After the drive cycle, the engine should be idling normally. - If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds and repeat step 6. 8. Once the engine speed has returned to normal, clear DTCs. Throttle Body Cleaning THROTTLE BODY CLEANING IMPORTANT: Over extended time and mileage, deposits may accumulate on the back of the throttle valve plate. The source of the deposit is exhaust gas recirculation (EGR) gas. Typically these deposits pose no problem. Occasionally the deposit may accumulate to a point where perceived pedal effort or throttle valve movement is effected. This procedure should not be performed on vehicles with mileage under 80 450 km (50,000 mi). 1. Remove the air intake duct. CAUTION: Turn OFF the ignition before inserting fingers into the throttle bore. Unexpected movement of the throttle blade could cause personal injury. NOTE: Do not insert any tools into the throttle body bore in order to avoid damage to the throttle valve plate. 2. Inspect the throttle body bore and the throttle valve plate for deposits. You will need to open the throttle valve in order to inspect all surfaces. NOTE: Do not use any solvent that contains Methyl Ethyl Ketone (MEK). This solvent may damage fuel system components. 3. Clean the throttle body bore and the throttle valve plate using a clean shop towel with GM top engine cleaner, GM P/N 1052626 (Canadian P/N 993026) or AC-Delco Carburetor Tune-Up Conditioner, P/N X66-P, or an equivalent product. 4.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8577 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8578 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8579 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8581 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8582 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8583 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8584 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8585 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8586 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8604 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8605 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8650 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8651 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8652 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8657 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8659 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8660 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8661 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8662 4. IMPORTANT: Apply the mylar tape with the aluminum side inward. This ensures good electrical contact with the drain wire. Re-assemble the cable. Rewrap the conductors with the mylar tape. - Use caution not to wrap the drain wire in the tape (1). - Follow the splicing instructions for copper wire and splice the drain wire. - Wrap the drain wire around the conductors and tape with mylar tape. 5.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8682 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8683 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8684 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8685 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8686 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8687 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8688 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8689 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8690 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8691 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8709 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7.

Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8710 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8711 3. Use a small flat-blade tool to push in one of the locking tabs while gently pulling on the same side of the nose piece. 4. Repeat the procedure for the other locking tab and remove the nose piece. 5. Remove the wire dress cover. The following is a general procedure for wire dress cover removal. Use this procedure as a guide, some dress cover removal procedures may vary. 6. Use fingers to squeeze the 2 locking legs of the cover. 7. Apply pressure and gently rock the cover until one locking leg is unseated. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8712 8. Continue to apply pressure and rock the cover until the second locking leg is unseated. Repeat procedure for the other side of the dress cover and remove the cover. 9. Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8713 3. Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1. Slide the new terminal into the correct cavity at the back of the connector. 2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire. 3.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8755 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8756 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8757 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8764 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8765 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8766 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8767 4. IMPORTANT: Apply the mylar tape with the aluminum side inward. This ensures good electrical contact with the drain wire. Re-assemble the cable. Rewrap the conductors with the mylar tape. - Use caution not to wrap the drain wire in the tape (1). - Follow the splicing instructions for copper wire and splice the drain wire. - Wrap the drain wire around the conductors and tape with mylar tape. 5. Tape over the entire cable. Use a winding motion when you apply the tape.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8787 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8788 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8789 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8790 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8791 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8792 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8793 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8794 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8795 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8796 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8814 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors.

The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8815 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

Continue to apply pressure and rock the cover until the second locking leg is unseated. Repeat procedure for the other side of the dress cover and remove the cover. 9. Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8860 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8861 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8862 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8871 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. DIAGNOSTIC FAULT INFORMATION TYPICAL SCAN TOOL DATA CIRCUIT/SYSTEM DESCRIPTION The crankshaft position (CKP) sensor circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, low reference circuit and an output signal circuit. The CKP sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 58-tooth reluctor wheel on the crankshaft. Each tooth on the reluctor wheel is spaced at 60-tooth spacing, with 2 missing teeth for the reference gap. The CKP sensor produces an ON/OFF DC voltage of varying frequency, with 58 output pulses per crankshaft revolution. The frequency of the CKP sensor output depends on the velocity of the crankshaft. The CKP sensor sends a digital signal, which represents an image of the crankshaft reluctor wheel, to the ECM as each tooth on the wheel rotates past the CKP sensor. The ECM uses each CKP signal pulse to determine crankshaft speed and decodes the crankshaft reluctor wheel reference gap to identify crankshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses CKP sensor output information to determine the camshaft relative position to the crankshaft, to control camshaft phasing, and to detect cylinder misfire. DIAGNOSTIC AIDS - Inspect the CKP sensor connector and the ECM connector for corrosion. - With a DTC set, the engine may crank for an extended period of time at start-up. CIRCUIT/SYSTEM VERIFICATION If DTC P0641 or P0651 are set diagnose those DTCs first. 1. With the ignition OFF, inspect the engine wiring harnesses carrying the CKP sensor circuits for the following conditions: - Close routing of secondary ignition wires - Close routing of aftermarket electrical equipment - Close to solenoids, motors, and relays - Correct any wire harness routing or component placement conditions, if it is determined to be a possible source of electrical interference. 2. Start the engine. Using the Live Plot function on the scan tool, select the CMP parameter. Change the minimum spec to 400 RPM, and the maximum spec to 4,000 RPM. Select the CKP sensor parameter. Change the minimum spec to 600 RPM, and the maximum spec to 3,300 RPM. 3. Observe the scan tool. 4. Quickly accelerate and release the accelerator pedal several time. Do not exceed 3,200 RPM. The graphed lines on the Live Plot display should track together across the screen. If the vehicle passes the Circuit/System Verification test, operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records data list.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8921 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8922 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8923 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8924 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8925 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8926 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8927 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8928 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8929 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8930 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8948 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8949 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8994 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8995 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 8996 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

The tool kit J-38125 contains the following items: - DuraSeal splice sleeves, in order to repair the SIR/SRS wiring - A special crimping tool - A heat torch - An instruction manual The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides the necessary low resistance contact integrity for these sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors SIR/SRS CONNECTOR REPAIR (PLASTIC BODY AND TERMINAL METAL PIN) The terminals in the SIR/SRS system are made with a special plating. This plating provides the necessary contact integrity for the sensitive, low energy circuits. Use the J-38125 SIR/SRS Terminal Repair Kit for repairing SIR/SRS terminals and connectors. Do not substitute any other terminals for those in the repair kit. The J-38125 SIR/SRS Terminal Repair Kit contains: Various terminated leads for sensing and diagnostic module (SDM) terminal replacement - Various connector positive assurance (CPA) locks for SIR/SRS connectors - Base of steering column pigtail connectors part number 12085514 - Yellow vinyl electrical tape Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9000 Pigtail repair packs are available for SIR/SRS connectors with eight or less terminals. Only the connector body is available for connectors with more than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the connector body. SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9001 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9003 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9004 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9005 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9046 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9047 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9048 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9049 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9050 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9051 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9052 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9053 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9054 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9055 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9074 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9119 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9120 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9121 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

IMPORTANT: You must perform the following procedures in the order listed. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip keeping all of the wire strands intact. Open the harness by removing any tape. 2. Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. 3. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 4. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent american wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 5. Slide a section of high temperature SCT1 shrink tubing down the length of wire to be spliced. Ensure that the shrink tubing will not interfere with the splice procedure. 6. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 7. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 8. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 9. Insert the wire into the DuraSeal splice sleeve barrel until the wire hits the barrel stop. 10. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9151 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9152 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9153 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9154 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9155 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9156 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9157 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9158 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9159 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9160 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9178 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9179 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9180 3.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9182 3. Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9224 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9225 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Crankshaft Position Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9226 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests.

See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check Vehicle - Review Strategy Based Diagnosis for an overview of the diagnostic approach. - Diagnostic Procedure Instructions provides an overview of each diagnostic category. DIAGNOSTIC FAULT INFORMATION TYPICAL SCAN TOOL DATA CIRCUIT/SYSTEM DESCRIPTION The crankshaft position (CKP) sensor circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, low reference circuit and an output signal circuit. The CKP sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 58-tooth reluctor wheel on the crankshaft. Each tooth on the reluctor wheel is spaced at 60-tooth spacing, with 2 missing teeth for the reference gap. The CKP sensor produces an ON/OFF DC voltage of varying frequency, with 58 output pulses per crankshaft revolution. The frequency of the CKP sensor output depends on the velocity of the crankshaft. The CKP sensor sends a digital signal, which represents an image of the crankshaft reluctor wheel, to the ECM as each tooth on the wheel rotates past the CKP sensor. The ECM uses each CKP signal pulse to determine crankshaft speed and decodes the crankshaft reluctor wheel reference gap to identify crankshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses CKP sensor output information to determine the camshaft relative position to the crankshaft, to control camshaft phasing, and to detect cylinder misfire. DIAGNOSTIC AIDS - Inspect the CKP sensor connector and the ECM connector for corrosion. - With a DTC set, the engine may crank for an extended period of time at start-up. CIRCUIT/SYSTEM VERIFICATION If DTC P0641 or P0651 are set diagnose those DTCs first. 1. With the ignition OFF, inspect the engine wiring harnesses carrying the CKP sensor circuits for the following conditions: - Close routing of secondary ignition wires - Close routing of aftermarket electrical equipment - Close to solenoids, motors, and relays - Correct any wire harness routing or component placement conditions, if it is determined to be a possible source of electrical interference. 2. Start the engine. Using the Live Plot function on the scan tool, select the CMP parameter. Change the minimum spec to 400 RPM, and the maximum spec to 4,000 RPM. Select the CKP sensor parameter. Change the minimum spec to 600 RPM, and the maximum spec to 3,300 RPM. 3. Observe the scan tool. 4. Quickly accelerate and release the accelerator pedal several time. Do not exceed 3,200 RPM. The graphed lines on the Live Plot display should track together across the screen. If the vehicle passes the Circuit/System Verification test, operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records data list.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9279 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9280 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9281 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9282 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9283 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9284 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9285 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9286 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9287 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9288 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9306 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors.

The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9307 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9352 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9353 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Knock Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 9354 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

An incorrect spark plug causes driveability conditions. Refer to Ignition System Specifications for the correct spark plug. - Ensure that the spark plug has the correct heat range. An incorrect heat range causes the following conditions: Spark plug fouling-Colder plug - Pre-ignition causing spark plug and/or engine damage-Hotter plug SPARK PLUG INSPECTION - Inspect the terminal post (1) for damage. Inspect for a bent or broken terminal post (1). - Test for a loose terminal post (1) by twisting and pulling the post. The terminal post (1) should NOT move. - Inspect the insulator (2) for flashover or carbon tracking, soot. This is caused by the electrical charge traveling across the insulator (2) between the terminal post (1) and ground. Inspect for the following conditions: Inspect the spark plug boot for damage. - Inspect the spark plug recess area of the cylinder head for moisture, such as oil, coolant, or water. A spark plug boot that is saturated causes arcing to ground. - Inspect the insulator (2) for cracks. All or part of the electrical charge may arc through the crack instead of the electrodes (3, 4). Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Technical Service Bulletins > Page 9396 - Inspect for evidence of improper arcing. Measure the gap between the center electrode (4) and the side electrode (3) terminals. An excessively wide electrode gap can prevent correct spark plug operation. - Inspect for the correct spark plug torque. Insufficient torque can prevent correct spark plug operation. An over torqued spark plug, causes the insulator (2) to crack. - Inspect for signs of tracking that occurred near the insulator tip instead of the center electrode (4). - Inspect for a broken or worn side electrode (3). - Inspect for a broken, worn, or loose center electrode (4) by shaking the spark plug. A rattling sound indicates internal damage. - A loose center electrode (4) reduces the spark intensity. - Inspect for bridged electrodes (3, 4). Deposits on the electrodes (3, 4) reduce or eliminates the gap. - Inspect for worn or missing platinum pads on the electrodes (3, 4), if equipped. - Inspect for excessive fouling. - Inspect the spark plug recess area of the cylinder head for debris. Dirty or damaged threads can cause the spark plug not to seat correctly during installation. SPARK PLUG VISUAL INSPECTION - Normal operation-Brown to grayish-tan with small amounts of white powdery deposits are normal combustion by-products from fuels with additives. - Carbon fouled-Dry, fluffy, black carbon or soot caused by the following conditions: Rich fuel mixtures Leaking fuel injectors - Excessive fuel pressure - Restricted air filter element - Incorrect combustion - Reduced ignition system voltage output Weak coils - Worn ignition wires - Incorrect spark plug gap - Excessive idling or slow speeds under light loads can keep spark plug temperatures so low that normal combustion deposits may not burn off. - Deposit fouling-Oil, coolant, or additives that include substances such as silicone, very white coating, reduces the spark intensity. Most powdery deposits will not effect spark intensity unless they form into a glazing over the electrode. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Technical Service Bulletins > Page 9397 Spark Plug: Service and Repair SPARK PLUG REPLACEMENT REMOVAL PROCEDURE NOTE: Observe the following service precautions: - Allow the engine to cool before removing the spark plugs. Attempting to remove spark plugs from a hot engine can cause the spark plugs to seize. This can damage the cylinder head threads. - Clean the spark plug recess area before removing the spark plug. Failure to do so can result in engine damage due to dirt or foreign material entering the cylinder head, or in contamination of the cylinder head threads. Contaminated threads may prevent proper seating of the new spark plug. - Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine. 1. Remove the spark plug wires from the spark plugs. 2. Remove the spark plugs (1) from the cylinder head. INSTALLATION PROCEDURE 1. NOTE: It is important to check the gap of all new and reconditioned spark plugs before installation. Pre-set gaps may have changed during handling. Use a round wire feeler gauge to be sure of an accurate check, particularly on used plugs. Installing plugs with the wrong gap can cause poor engine performance and may even damage the engine. Gap the spark plugs to the specifications. Refer to Ignition System Specifications. 2. NOTE: - Be sure plug threads smoothly into cylinder head and is fully seated. Use a thread chaser if necessary to clean threads in cylinder head. Cross-threading or failing to fully seat spark plug can cause overheating of plug, exhaust blow-by, or thread damage. Follow the recommended torque specifications carefully. Over or under-tightening can also cause severe damage to engine or spark plug. - Refer to Component Fastener Tightening Notice. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Technical Service Bulletins > Page 9398 IMPORTANT: ONLY when the cylinder head is replaced with a NEW cylinder head, the FIRST time the spark plugs are installed, tighten the spark plugs to 20 N.m (15 lb ft). All subsequent tightening of the spark plugs, tighten to 15 N.m (11 lb ft). Install the spark plugs to the cylinder head. Tighten the spark plugs to 15 N.m (11 lb ft). 3. Install the spark plug wires to the spark plugs.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9429 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9430 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9431 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9432 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9433 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9434 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9435 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9436 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9437 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9502 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9503 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9537 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9538 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9539 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9541 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9542 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9543 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9544 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9545 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9564 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors.

Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1. Slide the new terminal into the correct cavity at the back of the connector. 2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire. 3. To assemble the connector, reverse the Terminal Removal Procedure.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9610 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9620 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

Bulletin No.: 06-04-21-001 Date: May 17, 2006 INFORMATION Subject: Updated Transfer Case Connector Service Kit Now Available For Transfer Case Speed Sensor Wire Harness Connector that Comes Loose Or Connector Retainer Clip Breaks Models: 2007 and Prior GM Light Duty Trucks 2007 and Prior HUMMER H2, H3 2005-2007 Saab 9-7X with Four-Wheel Drive or All-Wheel Drive Technicians may find that when the transfer case speed sensor wire harness connector is removed, the connector lock flexes/bends and does not return to the original position. The transfer case speed sensor wire harness connector then has no locking device. On older vehicles, the plastic connector retainer becomes brittle and the clip may break as soon as it is flexed. In the past, the only service fix was to install a wire harness connector service pack, P/N 88987183. This repair procedure involved splicing a new service connector with an integral connector lock. This connector service kit is of the same design and was still prone to failure over time. A new connector service repair kit is now available, P/N 15306187, that is an updated design. This new kit should be used whenever the speed sensor wire harness connector requires replacement.

For Duramax(TM) diesel powered engines, refer to the latest version of Corporate Bulletin Number 08-06-04-006G. Supercede: This bulletin is being revised to add the 2011 model year. Please discard Corporate Bulletin Number 09-06-04-026A (Section 06 - Engine/Propulsion System). General Motors is identifying an increasing number of engine, transmission and catalytic converter part failures that are the result of non-GM (aftermarket) engine and transmission control calibrations being used. When alteration to the GM-released engine or transmission control calibrations occurs, it subjects powertrain and driveline components (engine , transmission, transfer case, driveshaft and rear axle) to stresses that were not tested by General Motors. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED dealer warranty claim submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM (aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed. Warranty coverage is based on the equipment and calibrations that were released on the vehicle at time of sale, or subsequently updated by GM. That's because GM testing and validation matches the calibration to a host of criteria that is essential to assure reliability, durability and emissions performance over the life of the warranty coverage and beyond. Stresses resulting from calibrations different from those tested and released by GM can damage or weaken components, leading to poor performance and or shortened life. Additionally, non-GM (aftermarket) issued engine control modifications often do not meet the same emissions performance standards as GM issued calibrations. Depending on state statutes, individuals who install engine control module calibrations that put the vehicle outside the parameters of emissions certification standards may be subject to fines and/or penalties. This bulletin outlines a procedure to identify the presence of non-GM (aftermarket) calibrations. GM recommends performing this check whenever a hard part failure is seen on internal engine or transmission components, or before an engine assembly or transmission assembly is being replaced under warranty. It is also recommended that the engine calibration verification procedure be performed whenever diagnostics indicate that catalytic converter replacement is indicated. The PQC has a process to confirm the ECM/PCM calibration is GM issued. The PQC will require a picture of the engine calibration verification screen, as outlined in this bulletin, before authorizing any V8 gas powered engine replacement. If a non-GM calibration is found and verification has taken place through GM, the remaining powertrain and driveline warranty will be blocked and notated in GMVIS and the dealership will be notified. This block prevents any UNAUTHORIZED warranty claim submission. 1. Connect the Tech 2(R) to the vehicle. 2. Go to: Diagnostics and build the vehicle. 3. Select: Powertrain. 4.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9749 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9750 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9751 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9752 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9753 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9754 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9755 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9756 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9757 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9857 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9858 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9859 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9860 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9861 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9862 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9863 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC.

Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9865 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9866 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible.

Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9930 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9931 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9940 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Actuators and Solenoids - Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9941 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9975 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9976 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9977 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9979 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9980 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9981 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9982 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9983 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 9984 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10003 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such.

Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10048 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests.

Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10083 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10084 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10085 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points.

Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10087 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10088 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10089 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10090 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10091 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10092 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10156 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10157 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

SIR/SRS Wiring Repairs SIR/SRS WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The Supplemental Inflatable Restraint (SIR) System/Supplemental Restraint System (SRS) requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working with the SIR/SRS, and the wiring components, such as connectors and terminals. IMPORTANT: Do not use the terminals in the kit in order to replace damaged SIR/SRS system terminals. Use either an SIR/SRS pigtail or a terminated lead from the SIR Repair Kit Tray. The tool kit J-38125 contains the following items: - DuraSeal splice sleeves, in order to repair the SIR/SRS wiring - A special crimping tool - A heat torch - An instruction manual The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides the necessary low resistance contact integrity for these sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors SIR/SRS CONNECTOR REPAIR (PLASTIC BODY AND TERMINAL METAL PIN) The terminals in the SIR/SRS system are made with a special plating. This plating provides the necessary contact integrity for the sensitive, low energy circuits. Use the J-38125 SIR/SRS Terminal Repair Kit for repairing SIR/SRS terminals and connectors. Do not substitute any other terminals for those in the repair kit. The J-38125 SIR/SRS Terminal Repair Kit contains: Various terminated leads for sensing and diagnostic module (SDM) terminal replacement - Various connector positive assurance (CPA) locks for SIR/SRS connectors - Base of steering column pigtail connectors part number 12085514 - Yellow vinyl electrical tape Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10162 Pigtail repair packs are available for SIR/SRS connectors with eight or less terminals. Only the connector body is available for connectors with more than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the connector body. SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10163 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10166 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape.

Please discard Corporate Bulletin Number 01-07-30-036G (Section 07 - Transmission/Transaxle). Some dealership technicians may have difficulty diagnosing DTC P0756, 2-3 Shift Valve Performance on 4L60-E, 4L65-E or 4L70E automatic transmissions. As detailed in the Service Manual, when the PCM detects a 4-3-3-4 shift pattern, DTC P0756 will set. Some customers may also describe a condition of a second, third or fourth gear start that may have the same causes but has not set this DTC yet. Below are some tips when diagnosing this DTC: ^ This is a performance code. This means that a mechanical malfunction exists. ^ This code is not set by electrical issues such as a damaged wiring harness or poor electrical connections. Electrical problems would cause a DTC P0758, P0787 or P0788 to set. ^ The most likely cause is chips/debris plugging the filtered AFL oil at orifice # 29 on the top of the spacer plate (48). This is a very small hole and is easily plugged by a small amount of debris. It is important to remove the spacer plate and inspect orifice # 29 and the immediate area for the presence of chips/debris. Also, the transmission case passage directly above this orifice and the valve body passage directly below should be inspected and cleaned of any chips/debris. For 2003 and newer vehicles the spacer plate should be replaced. The service replacement spacer plate is a bonded style with gaskets and solenoid filter screens bonded to the spacer plate. These screens can help to prevent plugging of orifice # 29 caused by small debris or chips. ^ This code could be set if the 2-3 shift valve (368) were stuck or hung-up in its bore. Inspect the 2-3 shift valve (368) and the 2-3 shuttle valve (369) for free movement or damage and clean the valves, the bore and the valve body passages. ^ This code could be set by a 2-3 shift solenoid (367b) if it were cracked, broken or leaking. Refer to Shift Solenoid Leak Test in the appropriate Service Manual for the leak test procedure. Based on parts return findings, a damaged or leaking shift solenoid is the least likely cause of this condition. Simply replacing a shift solenoid will not correct this condition unless the solenoid has been found to be cracked, broken or leaking. It is important to also refer to the appropriate Service Manual or Service Information (SI) for further possible causes of this condition.

Please discard Corporate Bulletin Number 08-07-30-035A (Section 07 - Transmission/Transaxle). Water or ethylene glycol in automatic transmission fluid (ATF) is harmful to internal transmission components and will have a negative effect on reliability and durability of these parts. Water or ethylene glycol in ATF will also change the friction of the clutches, frequently resulting in shudder during engagement or gear changes, especially during torque converter clutch engagement. Indications of water in the ATF may include: - ATF blowing out of the transmission vent tube. - ATF may appear cloudy or, in cases of extreme contamination, have the appearance of a strawberry milkshake. - Visible water in the oil pan. - A milky white substance inside the pan area. - Spacer plate gaskets that appear to be glued to the valve body face or case. - Spacer plate gaskets that appear to be swollen or wrinkled in areas where they are not compressed. - Rust on internal transmission iron/steel components. If water in the ATF has been found and the source of the water entry has not been identified, or if a leaking in-radiator transmission oil cooler is suspected (with no evidence of cross-contamination in the coolant recovery reservoir), a simple and quick test kit is available that detects the presence of ethylene glycol in ATF. The "Gly-Tek" test kit, available from the Nelco Company, should be obtained and the ATF tested to make an accurate decision on the need for radiator replacement. This can help to prevent customer comebacks if the in-radiator transmission oil cooler is leaking and reduce repair expenses by avoiding radiator replacement if the cooler is not leaking. These test kits can be obtained from: Nelco Company Test kits can be ordered by phone or through the website listed above. Orders are shipped standard delivery time but can be shipped on a next day delivery basis for an extra charge. One test kit will complete 10 individual fluid sample tests. For vehicles repaired under warranty, the cost of the complete test kit plus shipping charges should be divided by 10 and submitted on the warranty claim as a net item. The transmission should be repaired or replaced based on the normal cost comparison procedure. Important If water or coolant is found in the transmission, the following components MUST be replaced. - Replace all of the rubber-type seals. - Replace all of the composition-faced clutch plates and/or bands. - Replace all of the nylon parts. - Replace the torque converter. - Thoroughly clean and rebuild the transmission, using new gaskets and oil filter. Important The following steps must be completed when repairing or replacing. Flush and flow check the transmission oil cooler using J 45096. Refer to Corporate Bulletin Number 02-07-30-052F- Automatic Transmission Oil Cooler Flush and Flow Test Essential Tool J 45096 TransFlow. - Thoroughly inspect the engine cooling system and hoses and clean/repair as necessary.

Supercede: This bulletin is being revised to update the Parts Information. Please discard Corporate Bulletin Number 04-07-30-017A (Section 07 - Transmission/Transaxle). Effective with Julian date 4019 (January 19, 2004), the 4T65E transaxle cases and cooler fittings have changed and are not interchangeable with past models. The technician may find that when replacing the inlet or outlet transmission cooler lines, the new lines cannot be connected to the transmission. A change to the transmission cooler line fittings was implemented in production on February 1, 2004. The cooler line fittings were changed to a design with a longer lead in pilot (1). The cooler line fittings with the longer lead in pilot will not fit on models built before February 1, 2004. The longer lead in pilot fittings (1) (9/16-18 UNF) have replaced the shorter lead in pilot fittings (2) (3/8-18 NPSF w/check ball & 1/4-18 NPSF). If the transmission cooler lines will not connect, then replace them with the following cooler line fittings as appropriate with the older, shorter lead in pilot design: ^ For vehicles built prior to February 1, 2004, use Transmission Fluid Cooler Inlet Hose, P/N 20793004. ^ For vehicles built after February 1, 2004, use Transmission Fluid Cooler Inlet Hose, second design P/N 15264588. ^ For vehicles built prior to February 1, 2004, use Transmission Fluid Cooler Outlet Hose, P/N 20793005. ^ For vehicles built after February 1, 2004, use Transmission Fluid Cooler Outlet Hose, second design P/N 15264589.

Please discard Corporate Bulletin Number 01-07-30-042E (Section 07 - Transmission/Transaxle). Important For 2005 model year fullsize utilities and pickups, refer to Corporate Bulletin 05-07-30-012. Some vehicles may exhibit a clunk noise that can be heard on a 2-3 upshift or a 3-2 downshift. During a 2-3 upshift, the 2-4 band is released and the 3-4 clutch is applied. The timing of this shift can cause a momentary torque reversal of the output shaft that results in a clunk noise. This same torque reversal can also occur on a 3-2 downshift when the 3-4 clutch is released and the 2-4 band applied. This condition may be worse on a 4-wheel drive vehicle due to the additional tolerances in the transfer case. This is a normal condition. No repairs should be attempted.

Please discard Corporate Bulletin Number 99-07-30-030E (Section 07 - Transmission/Transaxle). Service Information Owners of some vehicles equipped with Hydra-Matic front wheel drive transaxles may comment on a grinding and/or growling noise that is noticeable when standing in PARK on a hill or slope with the engine running and the parking brake not applied. Under these conditions, the weight of the vehicle puts a load on the parking pawl which can create a "ground-out" path through the drive axles, front struts, springs and spring towers. Normal engine noise can be transmitted to the passenger compartment through the "ground-out" path. Owners concerned about this condition should be advised to apply the parking brake prior to shifting into PARK. This is the recommended procedure described in the Owners Manual. Applying the parking brake first will put the load of the vehicle on the rear brakes rather than on the parking pawl. Refer the owner to the appropriate Owner Manual for additional details and instructions.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10371 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10372 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10373 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10374 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10375 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10376 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10377 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10378 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10379 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10380 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire.

The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10444 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10445 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10446 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing.

Please discard Corporate Bulletin Number 01-07-30-010B (Section 07 - Transmission/Transaxle). The purpose of this bulletin is to help technicians determine when a torque converter should be replaced. Below is a list of general guidelines to follow. The converter should NOT be replaced if the following apply: ^ DTC P0742 - TCC stuck on is set. This code is almost always the result of a controls condition (i.e. stuck TCC solenoid/valve). Experience has shown that this code rarely indicates a mechanical concern within the torque converter. ^ The fluid has an odor or is discolored but no evidence of metal contamination. ^ Fine metal particles (traces of metal flakes/gray color to fluid ) are found in the converter. This is not harmful to the torque converter. ^ The vehicle has been exposed to high mileage. ^ A small amount of wear appears on the hub where the oil pump drive gear mates to the converter (RWD only). A certain amount of such wear is normal for both the hub and oil pump gear. Neither the converter nor the front pump assembly should be replaced. The torque converter should be replaced under any of the following conditions: ^ The vehicle has TCC shudder and/or no TCC apply. First complete all electrical and hydraulic diagnosis and check for proper engine operation. The converter clutch may be damaged. Also the converter bushing and/or internal 0-ring may be damaged. ^ Evidence of damage to the oil pump assembly pump shaft turbine shaft drive sprocket support and bearing or metal chips/debris in the converter. ^ Metal chips/debris are found in the converter or when flushing the cooler and the cooler lines. ^ External leaks in the hub weld area lug weld or closure weld. ^ Converter pilot is broken damaged or fits poorly into the crankshaft. ^ The converter hub is scored or damaged. ^ The transmission oil is contaminated with engine coolant engine oil or water. ^ If excessive end play is found after measuring the converter for proper end play (refer to Service Manual). ^ If metal chips/debris are found in the fluid filter or on the magnet and no internal parts in the unit are worn or damaged. This indicates that the material came from the converter. ^ The converter has an unbalanced condition that results in a vibration that cannot be corrected by following Converter Vibration Procedures. ^ Blue converter or dark circular ring between lugs. This condition will also require a complete cleaning of the cooler and a check for adequate flow Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter > Component Information > Technical Service Bulletins > A/T - Torque Converter Replacement Information > Page 10493 through the cooler. ^ Converter bearing noise determined by noise from the bell housing area in Drive or Reverse at idle. The noise is gone in Neutral and Park. ^ If silicon from the viscous clutch is found in the lower pan (4T80-E ONLY).

Supercede: This bulletin is being revised to update the Parts Information. Please discard Corporate Bulletin Number 04-07-30-017A (Section 07 - Transmission/Transaxle). Effective with Julian date 4019 (January 19, 2004), the 4T65E transaxle cases and cooler fittings have changed and are not interchangeable with past models. The technician may find that when replacing the inlet or outlet transmission cooler lines, the new lines cannot be connected to the transmission. A change to the transmission cooler line fittings was implemented in production on February 1, 2004. The cooler line fittings were changed to a design with a longer lead in pilot (1). The cooler line fittings with the longer lead in pilot will not fit on models built before February 1, 2004. The longer lead in pilot fittings (1) (9/16-18 UNF) have replaced the shorter lead in pilot fittings (2) (3/8-18 NPSF w/check ball & 1/4-18 NPSF). If the transmission cooler lines will not connect, then replace them with the following cooler line fittings as appropriate with the older, shorter lead in pilot design: ^ For vehicles built prior to February 1, 2004, use Transmission Fluid Cooler Inlet Hose, P/N 20793004. ^ For vehicles built after February 1, 2004, use Transmission Fluid Cooler Inlet Hose, second design P/N 15264588. ^ For vehicles built prior to February 1, 2004, use Transmission Fluid Cooler Outlet Hose, P/N 20793005. ^ For vehicles built after February 1, 2004, use Transmission Fluid Cooler Outlet Hose, second design P/N 15264589.

The torque has changed from 38 Nm (28 lb ft) to 32 Nm (23 lb ft). Tighten Tighten the new cooler fittings to 32 Nm (23 lb ft). The converter drain back check ball (420C) has been removed from the cooler line fitting and is now located in the channel plate. If you get a concern of no movement in the morning or after sitting for several hours, the cooler check ball should be inspected. The best way to determine where the check ball is located is to look at the cooler line fittings. The old fittings are different sizes (3/8-18 NPSF & 1/4-18 NPSF) and would contain the cooler check ball. The new fittings are the same size as each other (9/16-18 UNF) and do not have a cooler check ball.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10515 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10516 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10517 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10518 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10519 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10520 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10521 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10522 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10523 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10524 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10542 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors.

The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10543 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10588 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10589 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10590 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing.

Only the connector body is available for connectors with more than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the connector body. SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests.

Please discard Corporate Bulletin Number 02-07-30-052F (Section 07 - Transmission/Transaxle). Important All labor operations that include removal of the transmission from the vehicle include labor time to flush the transmission oil cooler system. The J 45096 transmission oil cooling system flush and flow test tool replaces current tool J 35944-A. J 45096 is a self-contained unit utilizing a 12-volt flow meter, shop air supply and DEXRON(R) VI automatic transmission fluid (ATF). In the flush mode, transmission fluid is cycled through the transmission oil cooling system. High-pressure air is automatically injected into the fluid stream adding agitation to the ATF oil to enhance the removal of contaminated ATF oil and debris. In the flow mode, an electronic flow meter is used to measure the flow capability of the ATF oil cooling system. A digital display indicates the ATF oil flow rate in gallons per minute (GPM) along with the amount of ATF oil in the supply vessel, supply vessel ATF oil temperature, machine cycles and the operating mode. The supply oil vessel has 30 L (32 qt) capacity and the waste oil vessel has 32 L (34 qt) capacity. The waste oil vessel is constructed of a translucent composite material that allows the user to easily identify the oil level. The waste oil vessel can accommodate vacuum evacuation and gravity draining. In the code mode, a random, encrypted code is generated that can be used for verification of flow test results. Current essential cooler line adapters are used to connect the J 45096 to the automatic transmission oil cooler lines that allows J 45096 to adapt to General Motors passenger cars and light duty trucks, current and past models (except the Pontiac Vibe, Wave and Chevrolet Aveo). The tool may be adapted for use on the Pontiac Vibe, Wave and Chevrolet Aveo by dealership personnel with a barbed hose connector and rubber hose obtained locally. The Vibe's/Wave's/Aveo's transmission has a transmission oil requirement which is slightly different than DEXRON(R) VI ATF. However, flushing the cooler with DEXRON(R) VI automatic transmission fluid is an acceptable service procedure. Very little fluid remains in the cooler after the flush procedure and the residual DEXRON(R) VI ATF in the cooler is compatible with the Vibe's/Wave's/Aveo's transmission fluid. Notice Insufficient oil flow through the ATF oil cooling system will cause premature transmission failure. The required minimum ATF oil flow rate reading is directly related to the supply oil temperature. Refer to the flow rate reference chart for the oil flow rate specification based on the temperature of the ATF in the supply vessel. Helpful Hints for Maintaining the Temperature at or above 18°C (65°F) Important - The temperature of the supply vessel oil must be 18°C (65°F) or greater for J 45096 to operate. It is recommended to store the J 45096 in an area of the dealership where the room temperature remains at or above 18°C (65°F) when not in use. - Do not attempt to increase the fluid temperature in the Transflow(R) machine with an engine oil dipstick, or any other immersion type heater. The Transflow(R) machine has a check valve in the supply reservoir. Inserting a heater will damage the check valve and the subsequent repair expense would be the dealer's responsibility. - A heater blanket, P/N J-45096-10, is available for the Transflow(R) transmission cooling system flushing tool. This heater fastens around the Transflow(R) internal supply vessel and runs on 110 volts AC. The heater will warm the ATF in the supply vessel to at least 18°C (65° F) and has a thermostat to hold a constant temperature. Store the Transmission Cooling System Service Tool, J 45096, Transflow(R) machine in a room where the temperature is maintained at or above 18°C (65°F). Keep the ATF level in the reservoir low when the Transmission Cooling System Service Tool, J 45096, Transflow(R), is not in use. Store several gallons of oil in an area where the temperature is maintained at or above 18°C (65°F). Fill the reservoir of the J 45096 as needed before using the machine on Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Cooler, A/T > Component Information > Technical Service Bulletins > A/T - Fluid Oil Cooler Flush > Page 10608 each repair. With the ATF in a tightly sealed container, place the container in a tub of hot water for a period of time. Then pour the ATF into the reservoir. This method works best with a low fluid level in the reservoir. Place the Transflow(R) machine in the direct sunlight with the cabinet door open to expose the reservoir to the rays of the warm sun. Flush / Flow Test Procedure Important All labor operations that include removal of the transmission from the vehicle and require the transmission oil pan or transmission side cover to be removed include labor time to flush the transmission oil cooler system. Refer to SI for Automatic Transmission Oil Cooler Flushing and Flow Test J 45096 for the appropriate procedure. Important The J 45096 can be used to flush the transmission oil cooler system on an Allison equipped vehicle, but the flow meter should not be utilized. Refer to SI for Automatic Transmission Oil Cooler Flushing and Flow Test J 45096 for the appropriate flow check procedure.

Please discard Corporate Bulletin Number 08-07-30-035A (Section 07 - Transmission/Transaxle). Water or ethylene glycol in automatic transmission fluid (ATF) is harmful to internal transmission components and will have a negative effect on reliability and durability of these parts. Water or ethylene glycol in ATF will also change the friction of the clutches, frequently resulting in shudder during engagement or gear changes, especially during torque converter clutch engagement. Indications of water in the ATF may include: - ATF blowing out of the transmission vent tube. - ATF may appear cloudy or, in cases of extreme contamination, have the appearance of a strawberry milkshake. - Visible water in the oil pan. - A milky white substance inside the pan area. - Spacer plate gaskets that appear to be glued to the valve body face or case. - Spacer plate gaskets that appear to be swollen or wrinkled in areas where they are not compressed. - Rust on internal transmission iron/steel components. If water in the ATF has been found and the source of the water entry has not been identified, or if a leaking in-radiator transmission oil cooler is suspected (with no evidence of cross-contamination in the coolant recovery reservoir), a simple and quick test kit is available that detects the presence of ethylene glycol in ATF. The "Gly-Tek" test kit, available from the Nelco Company, should be obtained and the ATF tested to make an accurate decision on the need for radiator replacement. This can help to prevent customer comebacks if the in-radiator transmission oil cooler is leaking and reduce repair expenses by avoiding radiator replacement if the cooler is not leaking. These test kits can be obtained from: Nelco Company Test kits can be ordered by phone or through the website listed above. Orders are shipped standard delivery time but can be shipped on a next day delivery basis for an extra charge. One test kit will complete 10 individual fluid sample tests. For vehicles repaired under warranty, the cost of the complete test kit plus shipping charges should be divided by 10 and submitted on the warranty claim as a net item. The transmission should be repaired or replaced based on the normal cost comparison procedure. Important If water or coolant is found in the transmission, the following components MUST be replaced. - Replace all of the rubber-type seals. - Replace all of the composition-faced clutch plates and/or bands. - Replace all of the nylon parts. - Replace the torque converter. - Thoroughly clean and rebuild the transmission, using new gaskets and oil filter. Important The following steps must be completed when repairing or replacing. Flush and flow check the transmission oil cooler using J 45096.

Please discard Corporate Bulletin Number 01-07-30-036G (Section 07 - Transmission/Transaxle). Some dealership technicians may have difficulty diagnosing DTC P0756, 2-3 Shift Valve Performance on 4L60-E, 4L65-E or 4L70E automatic transmissions. As detailed in the Service Manual, when the PCM detects a 4-3-3-4 shift pattern, DTC P0756 will set. Some customers may also describe a condition of a second, third or fourth gear start that may have the same causes but has not set this DTC yet. Below are some tips when diagnosing this DTC: ^ This is a performance code. This means that a mechanical malfunction exists. ^ This code is not set by electrical issues such as a damaged wiring harness or poor electrical connections. Electrical problems would cause a DTC P0758, P0787 or P0788 to set. ^ The most likely cause is chips/debris plugging the filtered AFL oil at orifice # 29 on the top of the spacer plate (48). This is a very small hole and is easily plugged by a small amount of debris. It is important to remove the spacer plate and inspect orifice # 29 and the immediate area for the presence of chips/debris. Also, the transmission case passage directly above this orifice and the valve body passage directly below should be inspected and cleaned of any chips/debris. For 2003 and newer vehicles the spacer plate should be replaced. The service replacement spacer plate is a bonded style with gaskets and solenoid filter screens bonded to the spacer plate. These screens can help to prevent plugging of orifice # 29 caused by small debris or chips. ^ This code could be set if the 2-3 shift valve (368) were stuck or hung-up in its bore. Inspect the 2-3 shift valve (368) and the 2-3 shuttle valve (369) for free movement or damage and clean the valves, the bore and the valve body passages. ^ This code could be set by a 2-3 shift solenoid (367b) if it were cracked, broken or leaking. Refer to Shift Solenoid Leak Test in the appropriate Service Manual for the leak test procedure. Based on parts return findings, a damaged or leaking shift solenoid is the least likely cause of this condition. Simply replacing a shift solenoid will not correct this condition unless the solenoid has been found to be cracked, broken or leaking. It is important to also refer to the appropriate Service Manual or Service Information (SI) for further possible causes of this condition.

Please discard Corporate Bulletin Number 01-07-31-002A (Section 07 - Transmission/Transaxle). This bulletin is being issued to inform dealers of an improved procedure to aid in the ease of bleeding the clutch hydraulic system for the above listed vehicles. This procedure can be used anytime air is introduced into the hydraulic system. Following this procedure may also reduce the number of unnecessary parts replaced for low clutch pedal reserve and high shift effort. Verify that all the lines and fittings are dry and secure. Clean the dirt and grease from the reservoir cap in order to ensure that no foreign substances enter the system. Remove the reservoir cap. Fill the reservoir to the proper level with the required fluid. Attach the J 43485 (Adapter) to the J 35555 (Mity Vac), or equivalent. Brake fluid will deteriorate the rubber on J 43485. Use a clean shop cloth to wipe away the fluid after each use. Place and hold the adapter on the reservoir filler neck to ensure a tight fit. In some cases, the adapter will fit into the reservoir opening. Apply a vacuum of 51-68 kPa (15-20 hg) and remove the adapter. Refill the reservoir to the proper level. Repeat Steps 6 and 7. If needed, refill the reservoir and continue to pull a vacuum until no more bubbles can be seen in the reservoir or until the fluid level no longer drops. The vehicle will move if started in gear before the Actuator Cylinder is refilled and operational. Start the vehicle the first time in neutral to help prevent personal injury from vehicle movement and see if the transmission will shift easily into gear. Pump the clutch pedal until firm (to refill actuator cylinder). Add additional fluid if needed. Test drive vehicle to ensure proper operation.

Please discard Corporate Bulletin Number 03-07-30-043 (Section 07 - Transmission/Transaxle). This bulletin is being issued to better explain how the Automatic Transmission Shift Lock Control (formerly known as Brake Transmission Shift Interlock (BTSI)) feature is intended to operate. Revised wording regarding the shift lock control system began appearing in the Owner Manuals beginning with the 2004 model year. The shift lock control feature was intended to prevent drivers from shifting out of Park with the vehicle running without the brakes applied. However, if the ignition switch is in the Accessory (ACC) position, it may be possible on some vehicles to move the shift lever out of Park WITHOUT first activating the brake. The shift lock control system is ONLY active when the ignition switch is in the RUN or ON position. This means that when the ignition switch is in the RUN or ON position, the shift lever cannot be moved out of the Park position without activating the brake. Some owners may feel that the shift lock control system prevents an unattended child from moving the vehicle. Please stress to owners, as stated in the Owner Manual, that children should NEVER be left unattended in a vehicle, even if the ignition key has been removed from the vehicle.

Please discard Corporate Bulletin Number 03-07-29-004F (Section 07 Transmission/Transaxle). Important Even though this bulletin attempts to cover operating characteristics of manual transmissions, it cannot be all inclusive. Be sure to compare any questionable concerns to a similar vehicle and if possible, with similar mileage. Even though many of the conditions are described as characteristics and may not be durability issues, GM may attempt to improve specific issues for customer satisfaction. The purpose of this bulletin is to assist in identifying characteristics of manual transmissions that repair attempts will not change. The following are explanations and examples of conditions that will generally occur in all manual transmissions. All noises will vary between transmissions due to build variation, type of transmission (usually the more heavy duty, the more noise), type of flywheel and clutch, level of insulation, etc. Basic Information Many transmission noises are created by the firing pulses of the engine. Each firing pulse creates a sudden change in angular acceleration at the crankshaft. These changes in speed can be reduced with clutch damper springs and dual mass flywheels. However, some speed variation will make it through to the transmission. This can create noise as the various gears will accel and decel against each other because of required clearances. Cold Operation Manual transmission operation will be affected by temperature because the transmission fluid will be thicker when cold. The thicker fluid will increase the amount of force needed to shift the transmission when cold. The likelihood of gear clash will also increase due to the greater time needed for the synchronizer assembly to perform its function. Therefore when the transmission is cold, or before it has reached operating temperature, quick, hard shifts should be avoided to prevent damage to the transmission. Gear Rattle Rattling or grinding (not to be confused with a missed shift type of grinding, also described as a combustion knock type of noise) type noises usually occur while operating the engine at low RPMs (lugging the engine). This can occur while accelerating from a stop (for example, a Corvette) or while operating at low RPMs while under a load (for example, Kodiak in a lower gear and at low engine speed). Vehicles equipped with a dual-mass flywheel (for example, a 3500 HD Sierra with the 6-speed manual and Duramax(R)) will have reduced noise levels as compared to vehicles without (for example, a 4500 Kodiak with the 6-speed manual and Duramax(R)). However, dual-mass flywheels do not eliminate all noise. Neutral Rattle There are often concerns of rattle while idling in neutral with the clutch engaged. This is related to the changes in angular acceleration described earlier. This is a light rattle, and once again, vehicles with dual mass flywheels will have reduced noise. If the engine is shut off while idling in neutral with the clutch engaged, the sudden stop of the engine will create a rapid change in angular acceleration that even dual mass flywheels cannot compensate. Because of the mass of all the components, this will create a noise. This type of noise should not be heard if the clutch is released (pedal pushed to the floor). Backlash Backlash noise is created when changing engine or driveline loading. This can occur when accelerating from a stop, coming to a stop, or applying and releasing the throttle (loading and unloading the driveline). This will vary based on vehicle type, build variations, driver input, vehicle loading, etc. and is created from the necessary clearance between all of the mating gears in the transmission, axle(s) and transfer case (if equipped). Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Manual Transmission/Transaxle > Component Information > Technical Service Bulletins > Manual Transmission - M/T Operating Characteristics > Page 10847 Shift Effort Shift effort will vary among different style transmissions and synchronizer designs. Usually the more heavy duty the transmission, the higher the shift effort because of the increased mass of the components. Shift effort can also be higher in cold weather because the fluid will be thicker. Medium duty transmissions will not shift as quickly as a Corvette transmission. To reduce shift effort, do not attempt to rush the shift - allow the synchronizers to work as designed. Shifting harder will only increase the chance of rushing past the synchronizer leading to grinding while shifting. Non-Synchronized Gears Some light duty truck transmissions in 1st gear (creeper-gear) and reverse gears in various transmissions, along with all gears in some medium duty transmissions, may be non-synchronized. This means there is not a mechanism to match input and output shaft speeds to allow for a smooth shift. This function is left up to the driver. This can be noticed if a shift into 1st or reverse is attempted while the vehicle is rolling or before the input shaft stops rotating leading to a gear grind. The grinding can be reduced by coming to a complete stop and pausing for a moment before shifting into the 1st or reverse gear. Some slight grinding can be expected. In medium duty non-synchronized transmissions, the driver must match input shaft (engine) speed to output shaft (driveshaft) speed with every shift. This can be accomplished by double clutching, or by using other methods. If the driver is not able to perform this function properly, there will be gear grinding with each improperly completed shift. Driver training may be required to correct this condition. Clutch brakes are used in medium duty non-synchronized transmissions to allow a shift into gear at a stop. The clutch brake is used to stop the input shaft from spinning, allowing a shift into gear at a stop without grinding. The clutch brake is activated by pressing the clutch pedal all the way to the floor. When the clutch brake is used, it is possible to have a blocked shift with the vehicle stationary. If this occurs, engage the clutch slightly to rotate the input gear to allow the shift. The clutch brake is intended to only be used while at a stop. Care must be taken to not activate the clutch brake while shifting between gears. This could lead to excessive grinding or a blocked or missed shift. Skip Shift Currently, the Cadillac CTS-V, Pontiac GTO, Chevrolet Corvette and Camaro SS (other models may follow) equipped with the 6-speed manual transmission have a feature referred to as a "skip-shift." This feature only allows a shift from 1st to 4th gear when the indicator lamp is illuminated on the dash. Dealers cannot disable this feature as it was established to help meet fuel economy standards. The conditions for this feature are: engine coolant at normal operating temperature, vehicle speed of 24-31 km/h (15-19 mph), 21% or less throttle being used (refer to Service Information or the Owner Manual for more details.)

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10948 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10949 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10950 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10951 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10952 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10953 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10954 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10955 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Shift Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 10956 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors.

Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.

Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve.

Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11056 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11057 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11058 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11059 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11060 IMPORTANT: - Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11061 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11062 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11063 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: - High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11064 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11065 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

While holding the removal tool in place, gently pull the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11083 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1. Slide the new terminal into the correct cavity at the back of the connector. 2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire. 3. To assemble the connector, reverse the Terminal Removal Procedure.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11129 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11130 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.

The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut.

Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Torque Converter Clutch Solenoid, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 11139 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.

When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

Speed Sensor: Technical Service Bulletins Drivetrain - Updated Transfer Case Speed Sensor Conn. Bulletin No.: 06-04-21-001 Date: May 17, 2006 INFORMATION Subject: Updated Transfer Case Connector Service Kit Now Available For Transfer Case Speed Sensor Wire Harness Connector that Comes Loose Or Connector Retainer Clip Breaks Models: 2007 and Prior GM Light Duty Trucks 2007 and Prior HUMMER H2, H3 2005-2007 Saab 9-7X with Four-Wheel Drive or All-Wheel Drive Technicians may find that when the transfer case speed sensor wire harness connector is removed, the connector lock flexes/bends and does not return to the original position. The transfer case speed sensor wire harness connector then has no locking device. On older vehicles, the plastic connector retainer becomes brittle and the clip may break as soon as it is flexed. In the past, the only service fix was to install a wire harness connector service pack, P/N 88987183. This repair procedure involved splicing a new service connector with an integral connector lock. This connector service kit is of the same design and was still prone to failure over time. A new connector service repair kit is now available, P/N 15306187, that is an updated design. This new kit should be used whenever the speed sensor wire harness connector requires replacement.

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice . Important: Before performing the antilock brake system (ABS) Automated Bleed Procedure, first perform a manual or pressure bleed of the base brake system. The automated bleed procedure is recommended when one of the following conditions exist: * Base brake system bleeding does not achieve the desired pedal height or feel * Extreme loss of brake fluid has occurred * Air ingestion is suspected in the secondary circuits of the brake modulator assembly The ABS Automated Bleed Procedure uses a scan tool to cycle the system solenoid valves and run the pump in order to purge any air from the secondary circuits. These circuits are normally closed off, and are only opened during system initialization at vehicle start up and during ABS operation. The automated bleed procedure opens these secondary circuits and allows any air trapped in these circuits to flow out toward the brake corners. Automated Bleed Procedure Notice: The Auto Bleed Procedure may be terminated at any time during the process by pressing the EXIT button. No further Scan Tool prompts pertaining to the Auto Bleed procedure will be given. After exiting the bleed procedure, relieve bleed pressure and disconnect bleed equipment per manufacturers instructions. Failure to properly relieve pressure may result in spilled brake fluid causing damage to components and painted surfaces. 1. Raise and support the vehicle. 2. Remove all 4 tire and wheel assemblies. 3. Inspect the brake system for leaks and visual damage. Repair or replace components as needed. 4. Lower the vehicle. 5.

The highest rate of wear normally occurs at the trailing edge of the disc brake pads. * Inspect the thickness of the disc brake pads (3) in order to ensure that they have not worn excessively. The disc brake pad wear should be approximately even per axle set. * Both front and rear disc brake pads have integral, audible wear sensors (1). When the disc brake pad wear reaches the minimum allowable thickness, the wear sensor contacts the disc brake rotor (2). The wear indicator will then produce an audible, high-pitched warning noise during wheel rotation. * Replace the disc brake pads when the friction surface (3) is worn to within 2 mm (0.080 in) of the mounting plates. * Remove the brake calipers and inspect the friction surfaces of the inner and outer disc brake pads to ensure that they are level. Place the disc brake pad friction surfaces together and measure the gap between the surfaces. If more than 0.5 mm (0.020 in) gap exists midway between the length of the disc brake pads, replace the disc brake pads. * Verify that any disc brake pad shims that may be required are in place and not damaged or excessively corroded. Replace any missing or damaged shims in order to preserve proper disc brake performance. * Replace the disc brake pads if any have separated from the mounting plates. * Inspect the disc brake pads friction surfaces for cracks, fractures, or damage which may cause noise or otherwise impair disc brake performance. * Inspect the noise insulators on the brake pad mounting plate.

Do not attempt any maneuvers that could jeopardize vehicle control. Failure to adhere to these precautions could lead to serious personal injury and vehicle damage. Caution: Refer to Brake Dust Caution . Burnishing the brake pads and brake rotors is necessary in order to ensure that the braking surfaces are properly prepared after service has been performed on the disc brake system. This procedure should be performed whenever the disc brake rotors have been refinished or replaced, and/or whenever the disc brake pads have been replaced. 1. Select a smooth road with little or no traffic. 2. Accelerate the vehicle to 48 km/h (30 mph). Important: Use care to avoid overheating the brakes while performing this step. 3. Using moderate to firm pressure, apply the brakes to bring the vehicle to a stop. Do not allow the brakes to lock. 4. Repeat steps 2 and 3 until approximately 20 stops have been completed. Allow sufficient cooling periods between stops in order to properly burnish the brake pads and rotors.

Due to this change, you are no longer required to enter the LRO measurement on the repair order or in the warranty system failure code section. The bulletin information below and the base brake labor operations have been updated accordingly. Due to this change it is more important than ever to properly maintain your brake lathe (per the Brake Lathe Calibration Procedure in this bulletin). Please discard Corporate Bulletin Number 00-05-22-002K (Section 05 Brakes). For your convenience, this bulletin updates and centralizes all GM's Standard Brake Service Procedures and Policy Guidelines for brake rotor and brake pad service and wear. For additional information, the Service Technical College lists a complete index of available Brake courses. This information can be accessed at www.gmtraining.com > resources > training materials > brakes courseware index. In Canada, refer to Service Know How course 55040.00V and Hydraulic Brake Certification program 15003.16H. Important PLEASE FAMILIARIZE YOURSELF WITH THESE UPDATES BEFORE PERFORMING YOUR NEXT GM BRAKE SERVICE. The following four (4) key steps are a summary of this bulletin and are REQUIRED in completing a successful brake service. 1. Measure and Document Pre-Service Rotor Thickness* (REQUIRED on Repair Order) determine rotor clean-up/refinish/replace 2. Properly clean ALL brake corner mating surfaces - hub, rotor and wheel 3. Properly clean-up/refinish rotor, measure and document post-service rotor thickness (REQUIRED on Repair Order) Important If it is determined the rotor needs to be refinished, verify lathe equipment is properly calibrated. 4. Properly reassemble the brake corner using proper torque tools, torque specification and torque sequence - wheel lug nuts. * The bulletin refers to Minimum Thickness specification as the minimum allowable thickness after refinish. Always refer to SI to verify the spec stamped on the rotor is the minimum thickness spec after refinish and not the discard spec.

Original Rotor Thickness, 2. Refinished Rotor Thickness are required and MUST be written/documented on the repair order, or for your convenience, complete the form (GM Brake Service Repair Order Documentation for Required Measurements) shown above and attach it to the repair order. If the Warranty Parts Center generates a request, this Documentation/Form must be attached to the repair order that is sent back. Important Documentation of brake lathe maintenance and calibration as recommended by the lathe manufacturer must be available for review upon request. Repair Order Documentation - Rotor Original And Refinished Thickness - REQUIRED When resurfacing a brake rotor or drum, the ORIGINAL thickness (measured thickness before refinish) and REFINISHED thickness (measured thickness after refinish) MUST be written/documented on the repair order hard copy for each rotor serviced. If a rotor replacement is necessary, only the original thickness measurement needs to be recorded. Repair Order Documentation - Explanation of Part Replacement - REQUIRED If replacement of a brake component is necessary, proper documentation on the repair order is required. See the following examples: ^ Brake rotor replacement - Customer comment was brake pulsation. Rotor was refinished on a prior brake service. After rotor measurement, it was determined that refinishing the rotor again would take it under the Minimum Thickness specification. ^ Brake pad replacement - Customer comment was brake squeak noise. On inspection, found pads contaminated by fluid leak at caliper.

Disclaimer GM Brake Service Procedure GM BRAKE SERVICE PROCEDURE 1. Remove the wheel and caliper. 2. Measure rotor thickness. In order to determine if the rotor can be refinished, do the following steps: Important Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes- Disc Brake Warranty Service And Procedures > Page 11365 If performing routine Brake Service for worn pads only, and the rotors are not damaged and measure within specification - DO NOT REFINISH ROTORS. 1. Remove the rotor(s). 2. Measure the rotor for original thickness using a brake micrometer. Multiple measure points should be taken and the lowest measurement should be recorded. 3. Reference the Minimum Thickness specification stamped on the backside of the rotor or SI for Minimum Thickness specification/other. In most cases, the rotor should be refinished unless the measurement taken makes it obvious that refinishing the rotor would take the measurement under the Minimum Thickness specification (then replacement is necessary). DO NOT use any other manufacturers rotor specifications. 3. ***Record the lowest ORIGINAL rotor thickness measurement on the repair order hard copy as noted in the "Repair Order Documentation - Rotor Refinish" section of this bulletin. 4. Clean all of the mating surfaces between the hub, the rotor and the wheel using the J 42450A Wheel Hub Cleaning Kit and J 41013 - Whiz Wheel(R). If rotors are not to be refinished - Go To Step 8. Important Cleaning all mating surfaces and making them free of corrosion, burrs and other debris (which includes removal of Hubless rotors) is critical and MUST be performed whether using an On-Car or Bench Lathe Refinish Procedure. 5. Be sure to follow the appropriate refinishing procedure listed below for the type of lathe you are using. Important Only replace the rotors if they do not meet the Minimum Thickness specification. Important DO NOT REFINISH NEW ROTORS. Important Only remove the necessary amount of material from each side of the rotor and note that equal amounts of material do not have to be removed from both sides on any brake system using a floating caliper. Important Prior to making the cut, install the recommended clip-on style disc silencer supplied with the lathe. Use of this silencer is critical to prevent chatter from occurring during the cut. Bench Type Lathe 1. Refinish the existing rotor on an approved, well-maintained lathe to guarantee smooth, flat and parallel surfaces. 2. Check for clean and true lathe adapters and make sure the arbor shoulder is clean and free of debris or burrs. For more information, see the "Brake Lathe Calibration Procedure (Bench-Type)" section in this bulletin. 3. On the outboard area of the rotor, position the cutting tools one eighth of an inch into the brake pad area of the rotor. Feed the cutting tools into the rotor until they cut the rotor to new metal, a full 360 degrees. Zero each dial and back off a full turn 4. Move the cutting bits to the middle of the rotor and do the same procedure. If zero is passed during the process, reset zero. Back off a full turn. 5. Position the cutting bits one eighth of an inch inside the inboard (closest to the hub) edge of the brake pad contact area. Do the same procedure. If zero is passed during the process, reset zero. 6. Back off a full turn and position the cutting bits all the way inboard in preparation to refinish the full rotor surface. Advance both tool cutters to the zero setting plus just enough to clean up the entire rotor surface. 7. After completing the refinish, sand both sides of the rotor for approximately one minute per side using a sanding block and 130-150 grit sandpaper to obtain a non-directional finish. On-Car Type Lathe 1. Reinstall the rotor(s). Important Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes- Disc Brake Warranty Service And Procedures > Page 11366 When using the On-Car lathe on vehicles equipped with limited slip (or posi-trac) rear system, it is critical that the rear drive shaft is disconnected/disengaged prior to operation of the On-Car lathe. Remember to mark and re-index the drive shaft correctly on re-assembly to prevent creating driveline vibration. Whenever the lathe drive motor is being switched on, the operator MUST keep their body out of the wheel well area until the machine has reached its normal operating RPM. 2. Refinish the existing rotor on an approved, well-maintained lathe to guarantee smooth, flat and parallel surfaces. Important When raising the vehicle on the lift, be sure to have it at a good working height (waist high is average) to accommodate mounting the On-Car lathe. Optimally, the center piston on the lathe trolley will be mid-travel. If the lathe trolley center piston is completely compressed (bottoming out) or inversely fully extended and hanging off the vehicle hub, this could affect the calibration time of the lathe. 3. Select the correct adapter for the vehicle you're working on and mount it to the hub with the vehicle lug nuts. Hand tighten 34-41 Nm (25-30 lb ft) the nuts using equal torque. DO NOT use impact wrenches, excessive torque will damage the adapter. Important Ensure the adapter sits flush on the rotor hat surface. Be sure to remove any rust, rotor retaining clips, etc. that may preclude the adapter from sitting flat on the mounting surface. 4. Connect the lathe to the adapter, turn on the lathe and activate the computer to compensate for run-out in the hub. 5. Once the computer indicates the compensation process was successful, on the outboard area of the rotor, position the cutting tools one eighth of an inch into the brake pad area of the rotor. Feed the cutting tools into the rotor until they cut the rotor to new metal, a full 360 degrees. Zero each dial and back off a full turn. 6. Move the cutting bits to the middle of the rotor and do the same procedure. If zero is passed during the process, reset zero. Back off a full turn. 7. Position the cutting bits one eighth of an inch inside the inboard (closest to the hub) edge of the brake pad contact area. Do the same procedure. If zero is passed during the process, reset zero. 8. Back off a full turn and position the cutting bits all the way inboard in preparation to refinish the full rotor surface. Advance both tool cutters to the zero setting plus just enough to clean up the entire rotor surface. 9. After completing the refinish, sand both sides of the rotor for approximately one minute per side using a sanding block and 130-150 grit sandpaper to obtain a non-directional finish. 10. Dismount the lathe, but leave the lathe adapter attached to the vehicle. 6. Once the rotor has been properly machined, wash the rotor with soap and water (use a mild dish washing soap) or wipe it clean with GM approved brake cleaner, P/N 88862650 (Canadian P/N 88901247). Important Thoroughly cleaning the rotor will prevent the possible transfer of finite metal dust left as a by-product of machining to the pad material during the seating process, thus reducing the opportunity for squeaks or other noises to occur. 7. ***Record the REFINISHED rotor thickness measurement on the repair order hard copy. Refer to the "Repair Order Documentation - Rotor Refinish" section of this bulletin. 8. Setting up to measure for Lateral Run Out (LRO): Important Measuring for Lateral Run Out (LRO) (steps 8 - 15) is no longer required however, these steps are being left in the overall procedure as a good check to be performed in the case of a repeat pulsation complaint. If you are not checking for LRO, go to step 16. Bench-Type Lathe 1. Ensure that the mating surfaces of the rotor hat section and the hub mating surface are clean and free of debris. 2. Mount the new, original or refinished rotor onto the vehicle hub. Important Always hold the rotor on the bottom half so any debris that may be dislodged from the vents will fall out instead of falling into the mounting area. Any movement or jarring from the rotor falling over on the studs can release rust from the vents on the rotor. 3. Tilt the top of the rotor in towards the vehicle so you can see the studs and ease the rotor onto the studs. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes- Disc Brake Warranty Service And Procedures > Page 11367 4. Slide the rotor all the way to the hub and hold it in place until you have placed one of the conical washers (with the tapered hole side facing out) and run the first lug nut up tight by hand so the rotor doesn't move when you release it. 5. Place the conical washers on the rest of the studs (with the tapered hole side facing out), start and snug the lug nuts by hand. 6. Using the one half inch drive impact wrench and a torque stick (J 39544) or equivalent, start with the lug nut opposite of the one you first tightened by hand and tighten the lug nuts using a star pattern until they touch the hub but do not completely torque. Then again, starting with the first lug nut you tightened by hand, tighten all the lug nuts in a star pattern to the specific vehicle torque specification. 7. DO NOT reinstall the caliper or the wheel at this time. On-Car Type Lathe 1. Leave the On-Car adapter on the wheel. 2. Proceed to Step 9. 9. Fasten the dial indicator to the steering knuckle so that the indicator needle contacts the rotor outboard friction surface approximately 6.35 mm (0.25 in) from the rotor's outer edge. The stylus should be perpendicular to the friction surface of the rotor. Important Make sure the dial indicator needle tip is screwed tight, a loose tip could cause false readings. 10. Measure for LRO. Follow the procedure below to determine if the LRO is within specification (0.050 mm (0.002 in) or LESS). 1. Rotate the rotor and locate the point on the rotor where the lowest dial indicator reading is indicated and set the dial indicator to zero. 2. Rotate the rotor from the low point and locate the point with the highest dial indicator reading (rotor "high spot"). Note the amount and mark the location of the "high spot" on the rotor and mark the closest wheel stud relative to this location. If the high point falls between two studs, mark both studs. In instances where the vehicle has "capped lug nuts" you should mark the hub. 11. If the Lateral Run Out (LRO) measurement is 0.050 mm (0.002 in) or LESS, no correction is necessary. Go to Step 15 if this is the first rotor completed. Go to Step 16 if this is the second rotor completed. If the LRO is GREATER than 0.050 mm (0.002 in), go to Step 12. 12. If the LRO measurement is greater than 0.050 mm (0.002 in), use the following procedure to correct for LRO: Important If the LRO measurement is over 0.279 mm (0.011 in), determine the source or cause of the LRO and correct it (i.e. verify drive axle nut torque specification, refinished rotor is source of LRO due to a lathe qualification issue - see "Brake Lathe Calibration Procedure"). Hubless Rotor 1. Remove the rotor and using the Brake Align(R) application chart (found in TSB 01-05-23-001B), choose the correct plate to bring the rotor LRO to 0.050 mm (0.002 in) or less. The plates come in 0.0762 mm (0.003 in), 0.1524 mm (0.006 in) and 0.2286 (0.009 in) compensation. For more information on proper plate selection, see the instruction video/DVD included in the "Brake Align(R)" kit or TSB 01-05-23-001B. 2. Align the V-notch of the selected Brake Align(R) correction plate to the marked wheel stud ("high spot") or between the two points marked (if the "high spot" is between two wheel studs). Important IF Brake Align(R) Correction Plates are not available for the vehicle being serviced, refer to SI Document - Brake Rotor Assembled Lateral Runout Correction for correcting LRO. Important Per Brake Align(R) manufacturer, NEVER attempt to stack two or more Correction Plates together on one hub. NEVER attempt to reuse a previously installed Correction Plate. 3. Reinstall the rotor using the same method and precautions as the first time - found in Step 8. Make sure to index the rotor correctly to the marks made in step 10, otherwise LRO will be comprised. Hubbed / Captured / Trapped Rotor 1. Measure the rotor thickness. 2. Refinish or replace the rotor (see Service Information for further details). Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes- Disc Brake Warranty Service And Procedures > Page 11368 13. Use a Dial Indicator to measure the rotor to verify the LRO is within specification. 14. If using, BENCH LATHE - DO NOT remove conical washers and lug nuts at this time. ON-CAR LATHE - You must remove adapter and install conical washers and lug nuts to retain rotor position. Important For Hubless rotor design, while removing the adapter, you must hold the rotor tight to the hub and install the top conical washer and lug nut first to ensure no debris falls between the surface while removing the adapter. Then, install the remaining conical washers and lug nuts. Otherwise, LRO will be comprised. 15. Perform Steps 1 through 7 on the opposite side of the vehicle (steps 1-12, if performing LRO). 16. Reinstall the rotors on both sides of the vehicle and perform the following steps: 1. Reinstall the calipers and pads. 2. Pump the brakes to pressurize the calipers. 3. Remove the lug nuts/conical washers. 4. Install and properly torque the wheels. Important It is critical to follow the star pattern wheel torque procedure and use the proper tools (torque stick or torque wrench) as referenced in SI. 17. Road test the vehicle to verify the repairs. Brake Lathe Calibration Procedure BRAKE LATHE CALIBRATION PROCEDURE Calibration of the brake lathe should be performed and recorded monthly or whenever post-service brake rotor LRO measurements are consistently reading above specification. BENCH-TYPE LATHE Use the following procedure to calibrate a Bench-type brake lathe: 1. After refinishing a rotor, loosen the arbor nut and while holding the inside bell clamp to keep it from rotating, rotate the rotor 180 degrees. 2. Retighten the arbor nut and set the dial indicator on the rotor using the same instructions as checking the run out on the vehicle. 3. Rotate the arbor and read the runout. 4. Divide the reading by two and this will give you the amount of runout the lathe is cutting into the rotor. Important If there is any runout, you will need to machine the inside bell clamp in place on the lathe (this procedure is for a Bench type lathe ONLY, DO NOT machine inside the bell clamp on an On-Car type lathe). Machining the Inside Bell Clamp (Bench Type Lathe Only) Any nicks or burrs on the shoulder of the arbor must be removed. An 80-grit stone can be used to accomplish this. Spray WD-40(R) on the shoulder and with the lathe running, hold the stone flat against the shoulder surface using slight pressure. When the burrs are gone, clean the surface. Burrs must also be removed from the hub of the inside bell clamp. This can be accomplished with the stone and WD-40(R). Keep the stone flat on the hub while removing the burrs. After removing the burrs, clean the hub. Place the bell clamp on the arbor of the lathe and use the small radius adapters first and then spacers to allow you to tighten the arbor nut to secure the bell clamp to the lathe. Position the tool bit in the left hand of the rotor truer so you can machine the face of the bell clamp. Machine the face of the bell clamp taking just enough off of it to cut the full face of the clamp the full 360 degrees. Before you loosen the arbor nut, match mark the hub of the bell clamp to the arbor and line up these marks before machining a rotor. A magic marker can be used to make the match marks. Machine a rotor and recheck the calibration. Repeat this procedure on all Inside Bell Clamps used. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes- Disc Brake Warranty Service And Procedures > Page 11369 Important If runout is still present, contact the brake lathe supplier. ON-CAR TYPE LATHE Use the following procedure to calibrate an On-Car brake lathe: 1. Connect the lathe to a vehicle using the appropriate adapter. 2. Attach a vise-grip dial indicator to a fixed point in the wheel well and bring the dial indicator to a flat surface on the cutting head. 3. Turn on the lathe and press the "start" button so the lathe begins to compensate. 4. Once compensation is complete, note the runout as measured by the dial indicator. Measured runout at this point is overstated given that it is outside the rotor diameter. 5. If runout is in excess of 0.1016 mm (0.004 in) (0.050 mm (0.002 in) as measured within the rotor diameter), calibration must be tightened. Follow manufacturer's instructions for tightening the calibration of the lathe. This information is found in the manual supplied with the lathe. Important If the machine is taking a long time to compensate during normal use, prior to checking the lathe calibration, it is recommended that the machine be disconnected from the adapter and the adapter (still connected to the vehicle) is rotated 180 degrees and the machine reattached. This will accomplish two things: - It will re-verify the machine is properly attached to the adapter. - It will change the location of the runout (phase) relative to the machine and thus possibly allow for quick compensation as a result of the position change. The following information has been added as a reference to ensure your Pro-Cut PFM lathe provides a consistent smooth surface finish over long term usage. Cutting Tips / Depth of Cut / Tip Life The cutting tips must be right side up. Reference marks always face up. The cutting tips may not have chips or dings in the surface of the points. Cuts of 0.1016-0.381 mm (0.004-0.015 in) will provide the best surface finish and the optimal tip life. When cleaning or rotating the cutting bits, make sure that the seat area for the tip on the tool is free and clear of debris. Cutting Head On each brake job, the technician must center the cutting head for that particular vehicle using one of the mounting bolt holes on the slide plate. Once the head is centered, it is vital that the technician use one hand to push the head firmly and squarely back into the dovetail on the slide plate while using the other hand to tighten the Allen-Hex bolt that secures the head. Failure to do this could result in chatter occurring during the cut. Tool Holder Plate (Cutting Head) The tool holder plate is the plate that the cutting arms are attached to. It can bend or break if a technician accidently runs the cutting arms into the hub of the rotor while the rotor is turning. (Cuts of more than 0.508 mm (0.020 in) can also bend this plate). Once bent, the lathe will most likely not cut properly until the tool holder plate is replaced. In order to verify the condition of the tool holder plate on a machine that will not cut right, remove the mounting bolt and remove the cutting head from the slide plate. With the cutting head titled at an angle, lay the long edge of the tool holder plate down on the flat part of the slide plate. If any gap can be seen between the edge and the slide plate, the tool holder plate is bent and the source of vibration. Also check to ensure that the cutting arms are lying flat on the upper side of the tool holder plate. If the mounting arm post is bent, it will show itself by having the back of the cutting arm lifting off the surface of the tool holder. Gib Adjustment / Loose Gib As wear occurs between the slide plate and the box it rides on, you must take up the slack. You do this by way of a moveable wedge, which we call the gib. Your lathe manual details adjustment process, which you should perform when required after monthly checks or whenever surface finish is inconsistent. Brake Pulsation BRAKE PULSATION Brake pulsation is caused by brake rotor thickness variation. Brake rotor thickness variation causes the piston in the brake caliper, when applied, to "pump" in and out of the caliper housing. The "pumping" effect is transmitted hydraulically to the brake pedal. Brake pulsation concerns may result from two basic conditions: Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes- Disc Brake Warranty Service And Procedures > Page 11370 1. Thickness Variation Pulsation is Caused by Lateral Run Out (LRO). LRO on a brake corner assembly is virtually undetectable unless measured (with a dial indicator after the brake service) and will not be detected as brake pulsation during an after brake service test drive. If the brake corner is assembled with excessive LRO (greater than 0.050 mm (0.002 in), thickness variation will develop on the brake rotor over time and miles. Excessive LRO will cause the brake pads to wear the brake rotors unevenly, which causes rotor thickness variation. Pulsation that is the result of excessive Lateral Run Out usually develops in 4,800-16,000 km (3,000-10,000 mi). The more excessive the LRO, the faster the pulsation will develop. LRO can also be induced when uneven torque is applied to wheel nuts (lug nuts). Improper wheel tightening after tire rotation, spare tire usage, brake inspection, etc. can be the cause of brake pulsation. Again, it usually takes 4,800-16,000 km (3,000-10,000 mi) AFTER the service event for the condition to develop. The customer does not usually make the connection between the service event and the awareness of the pulsation. The proper usage of torque wrenches and/or torque sticks (torque limiting sockets) will greatly reduce or eliminate the pulsation conditions after wheel service events. The improper use of impact wrenches on wheel nuts greatly increases the likelihood of pulsation after wheel service. The following are examples of pulsation conditions and reimbursement recommendations: - If the customer noticed the condition between 4,800-16,000 km (3,000-10,000 mi) and it gradually got worse, normally the repair would be covered. The customer may tolerate the condition until it becomes very apparent. - If a GM dealer performed a prior brake service, consider paying for the repair and then strongly reinforce proper brake lathe maintenance. - If the customer had the brake service done outside of a GM dealership, normally GM would not offer any assistance. - If a customer indicated they had wheel service, ask who performed the service. Then; - If a GM dealer performed the service, consider paying for the repair and then strongly reinforce the use of torque sticks at the dealer. Two common size torque sticks cover 90% of all GM products. Each technician needs to use torque sticks properly every time the wheel nuts are tightened. - If the customer had the wheel service done outside of a GM dealership, normally GM would not offer any assistance. 2. Thickness Variation Pulsation Caused by Brake Rotor Corrosion - Rotor corrosion is another form of thickness variation, which can cause a pulsation concern and can be addressed as follows: - Cosmetic Corrosion: In most instances rotor corrosion is cosmetic and refinishing the rotor is unnecessary. - Corrosion - Pulsation Caused by Thickness Variation (Lot Rot / Low Miles - 0-321 km (0-200 mi): At times more extensive corrosion can cause pulsation due to thickness variation. This usually happens when the vehicle is parked for long periods of time in humid type conditions and the braking surface area under the pads corrodes at a different rate compared to the rest of the braking surface area. Cleaning up of braking surfaces (burnishing) can be accomplished by 10 - 15 moderate stops from 56- 64 km/h (35 - 40 mph) with cooling time between stops. If multiple moderate braking stops do not correct this condition, follow the "Brake Rotor Clean-Up Procedure" below. - Corrosion - Pulsation Caused by Thickness Variation (without rotor flaking / higher mileage 3,200-8,000 km (2,000-5,000 mi): In some cases, more extensive corrosion that is not cleaned up by the brake pad over time and miles can cause the same type of pulsation complaint due to thickness variation. In these cases, the rotor surface is usually darker instead of shiny and a brake pad foot print can be seen against the darker surface. This darker surface is usually due to build-up, on the rotor material surface, caused by a combination of corrosion, pad material and heat. To correct this condition, follow the "Brake Rotor Clean-up Procedure" below. - Corrosion - Pulsation Caused by Thickness Variation (with rotor flaking / higher mileage - 8,000 + km (5,000 + miles) : At times, more extensive corrosion over time and miles can cause pulsation due to thickness variation (flaking). This flaking is usually a build up, mostly on the rotor material surface, caused by a combination of corrosion, pad material and heat. When rotor measurements are taken, the low areas are usually close to the original rotor thickness (new rotor) measurement and the high areas usually measure more than the original rotor thickness (new rotor) measurement (depending on mileage and normal wear). To correct this condition, follow the "Brake Rotor Clean-up Procedure" described below. Important In some flaking instances, cleaning-up this type of corrosion may require more rotor material to be removed then desired. Customer consideration should be taken in these situations and handled on a case by case basis, depending on the amount/percentage of rotor life remaining and the vehicle's warranty time and miles. Brake Rotor Clean-Up Procedure Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes- Disc Brake Warranty Service And Procedures > Page 11371 BRAKE ROTOR CLEAN-UP PROCEDURE Clean-up the rotors on an approved, well-maintained brake lathe to guarantee smooth, flat and parallel surfaces. Check for clean and true lathe adapters and make sure the arbor shoulder is clean and free of debris or burrs. For more information see the "Brake Lathe Calibration Procedure" section in this bulletin. 1. On the outboard area of the rotor, position the cutting tools one eighth of an inch into the brake pad area of the rotor. Feed the cutting tools into the rotor until they cut the rotor to new metal, a full 360 degrees. Zero each dial and back off a full turn. 2. Move the cutting bits to the middle of the rotor and do the same procedure. If zero is passed during the process, reset zero. Back off a full turn. 3. Position the cutting bits one eighth of an inch inside the inboard (closest to the hub) edge of the brake pad contact area. Do the same procedure. If zero is passed during the process, reset zero. 4. Back off a full turn and position the cutting bits all the way inboard in preparation to refinish the full rotor surface. Advance both tool cutters to the zero setting plus just enough to clean up the entire rotor surface. 5. After completing the refinish, sand both sides of the rotor for approximately one minute per side using a sanding block and 130-150 grit sandpaper to obtain a non-directional finish. Important Only remove the necessary amount of material from each side of the rotor and note that equal amounts of material do not have to be removed from both sides on any brake system using a floating caliper. Important In many of these instances, such a minimal amount of material is removed from the rotor that customer satisfaction is not a concern for future brake services. This procedure is intended to "Clean-up" the rotor surface and should be conveyed to the customer as such - not as "cut", "refinish" or "machine", which tends to be terms understood as a substantial reduction of rotor material/life. If the brake lathe equipment being used is not capable of removing minor amounts of material while holding tolerances, further lathe maintenance, repair, updates or equipment replacement may be necessary. Brake Noise BRAKE NOISE Some brake noise is normal and differences in loading, type of driving, or driving style can make a difference in brake wear on the same make and model. Depending on weather conditions, driving patterns and the local environment, brake noise may become more or less apparent. Verify all metal-to-metal contact areas between pads, pad guides, caliper and knuckles are clean and lubricated with a thin layer of high temperature silicone grease. Brake noise is caused by a "slip-stick" vibration of brake components. While intermittent brake noise may be normal, performing 3 to 4 aggressive stops may temporarily reduce or eliminate most brake squeal. If the noise persists and is consistently occurring, a brake dampening compound may be applied to the back of each pad. This allows parts to slide freely and not vibrate when moving relative to each other. Use Silicone Brake Lubricant, ACDelco P/N 88862181 (Canadian P/N 88862496) or equivalent. The following noises are characteristics of all braking systems and are unavoidable. They may not indicate improper operation of the brake system. Squeak/Squeal Noise: - Occurs with front semi-metallic brake pads at medium speeds when light to medium pressure is applied to the brake pedal. - Occasionally a noise may occur on rear brakes during the first few stops or with cold brakes and/or high humidity. Grinding Noise: - Common to rear brakes and some front disc brakes during initial stops after the vehicle has been parked overnight. - Caused by corrosion on the metal surfaces during vehicle non-use. Usually disappears after a few stops. Groan Noise: A groan type noise may be heard when stopping quickly or moving forward slowly from a complete stop. This is normal. On vehicles equipped with ABS, a groan or moan type noise during hard braking applications or loose gravel, wet or icy road conditions is a normal function of the ABS activation. Key Points - Frequently Asked Questions KEY POINTS - FREQUENTLY ASKED QUESTIONS - Q: How do on-car lathes react to Axle Float? Does the play affect the machining of the rotor, either surface finish or LRO? Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes- Disc Brake Warranty Service And Procedures > Page 11372 A: Because the Pro-Cut on-car lathe adjusts in a live mode while spinning the hub/rotor, the dynamics of a floating axle are effectively eliminated. Once the lathe is compensated, there is no difference in the cutting/surface finish and LRO are just the same as with a non-floating axle. - Q: Which lathe is essential for performing brake work, the bench or on-car? A: Dealers must have a well maintained bench lathe and well maintained on-car lathe. These lathes need to be calibrated on a monthly basis. BOTH lathes are essential to providing quality brake service. - Q: What is the expected tip life for an on-car lathe? A: The geometry and composition of the Pro-Cut tips are designed for "single pass" cutting. When using the Pro-Cut the cutting depth should be set to take all material needed to get below rust grooves, eliminate all run-out and resurface the entire disc in a single pass. Cuts of 0.1016-0.381 mm (0.004-0.015 in) will provide the best surface finish and the optimal tip life. No "skim cut" or "finish cut" is needed. Failure to follow this procedure will shorten tip life. The Pro-cut tips will last between 7-12 cuts per corner. With three usable corners, a pair of tips is good for at least 21 cuts. - Q: Why does GM recommend the use of single pass (referred to as "positive rake") bench and on-car brake lathes? A: GM Service and GM Brake Engineering have performed competitive evaluations on a significant number of bench and on-car brake lathes. These tests measured critical performance characteristics such as flatness, surface finish and the ability of the lathe to repeat accuracy over many uses. In each test, single pass lathe designs out performed the competitors. Single pass brake lathes are more productive requiring less time to perform the same procedure. - Q: Is it okay to leave the caliper/pads installed while cutting rotors using an on-car lathe? A: On-car lathes should never be used with the pads and calipers installed on the vehicle. The debris from cutting the rotors can contaminate the brake pads/calipers which can lead to other brake concerns and comebacks. - Q: What information needs to be documented on the Repair Order? A: Any claim that is submitted using the labor operations in this bulletin, must have the Original Rotor Thickness and Refinish Rotor Thickness (if refinished) documented on the repair order. For more information, refer to the "Repair Order Required Documentation" section of this bulletin. All Warranty Repair Orders paid by GM, are subject to review for compliance and may be debited where the repair does not comply with this procedure. Brake Warranty BRAKE WARRANTY Brake Rotors: - Brake rotor warranty is covered under the terms of the GM New Vehicle Limited Warranty. Reference the vehicle's warranty guide for verification. - Rotors should not be refinished or replaced during normal/routine pad replacement. - Rotors should not be refinished or replaced and is ineffective in correcting brake squeal type noises and/or premature lining wear out. - Rotors should not be refinished or replaced for cosmetic corrosion. Clean up of braking surfaces can be accomplished by 10-15 moderate stops from 56-64 km/h (35-40 mph) with cooling time between stops. - Rotors should not be refinished or replaced for rotor discoloration/hard spots. - Rotors should be refinished NOT replaced for Customer Pulsation concerns. This condition is a result of rotor thickness variation, usually caused by LRO (wear induced over time and miles) or corrosion (Lot Rot). - When rotor refinishing, only remove the necessary amount of material from each side of the rotor and note that equal amounts of material do not have to be removed from both sides on any brake system using a floating caliper. - Rotors should be refinished for severe scoring - depth in excess of 1.5 mm (0.060 in). Important If the scoring depth is more than 1.5 mm (0.060 in) after the rotor is refinished, it should be replaced. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes- Disc Brake Warranty Service And Procedures > Page 11373 - It is not necessary to replace rotors in pairs. Rotors may be replaced individually. However, caution should be exercised, as a variance in surface finish may cause a brake pull condition. - New rotors should not be refinished before installation. Original equipment rotor surfaces are ground to ensure smooth finish and parallelism between mounting and friction surfaces. If a new rotor has more than 0.050 mm (0.002 in) Lateral Run Out (LRO) when properly mounted on the hub, correct it using one of the following methods: 1. For hubless rotor designs, use the correction plate procedure found in the "GM Brake Service Procedure for Hubless Rotors" outlined in this bulletin. 2. For hubbed/trapped/captured rotor designs, refinish the rotor using an On-Car lathe and the procedure outlined in this bulletin. - Never reuse rotors that measure under the Minimum Thickness specification. In this instance, the rotor should be replaced. Important If the Minimum Thickness specification is not visible on the rotor, reference Service Information (SI) for the specific vehicle application. DO NOT use any other manufacturers rotor specifications. Brake Pads: Important When determining the warranty coverage (as an example) - if all four front or four rear brake pads are excessively worn evenly, that would NOT be covered under warranty since this type of wear is most likely due to driving habits or trailering. However, if the brake pads are excessively worn un-evenly, side-to-side or same side/inner-to-outer pads, then consideration should be given to cover this under warranty since this type of wear is most likely due to poor operation of other braking components. - Consideration should be given for covering brake pads up to 39,000 km (24,000 mi) (excluding owner abuse, excessive trailering, or the situations that would not be considered normal use). - Installation of new rotors does not require pad replacement. Do not replace pads unless their condition requires it - excessively worn, damage or contaminated. Brake Wear: Several factors impact brake lining wear and should be taken into account when reviewing related issues: - heavy loads / high temperatures / towing / mountainous driving / city driving / aggressive driving / driver braking characteristics (left foot or two feet) The following are conditions that may extend brake lining wear: - light loads / highway driving / conservative driving / level terrain Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes- Disc Brake Warranty Service And Procedures > Page 11374 Brake Rotor/Disc: Technical Service Bulletins Brakes - Rotor/Drum Refinishing Labor Operations Bulletin No.: 06-05-22-007 Date: November 30, 2006 WARRANTY ADMINISTRATION Subject: Brake Rotor/Drum Refinishing Labor Operations Models: 2005-2007 GM Passenger Cars and Light Duty Trucks (including Saturn) 2005-2007 HUMMER H2 2006-2007 HUMMER H3 2005-2007 Saab 9-7X (Canada Only) The purpose of this bulletin is to advise dealership personnel of labor operation changes relating to brake repairs. Existing brake rotor and drum labor operations have been revised to remove the refinishing times and new labor operations have been established for refinishing brake rotors or drums. The changes will become effective with the release of the December 2006 Labor Time Guide. The following changes: Applies to all 2005-2007 vehicles, unless 2005 was the last year of production for that particular model. May apply to 2004 and prior models years if the vehicle was produced after 2005 - e.g. TrailBlazer, Envoy, etc. Where the new labor operations for refinishing rotors or drums do not apply, the existing labor operations will still contain time for refinishing. Always refer to the Labor Time Guide for the appropriate labor operations and time for the vehicle being repaired.

Thickness variation exceeding the maximum acceptable level can cause brake pulsation. * Brake rotor assembled lateral runout (LRO) exceeding the maximum allowable specification can cause thickness variation to develop in the brake rotor over time, usually between 4 800-11 300 km (3,000-7,000 mi). Review the following acceptable methods for bringing the brake rotor assembled LRO to within specifications. Determine which method to use for the specific vehicle being repaired. * The indexing method of correcting assembled LRO is most effective when the LRO specification is only exceeded by a relatively small amount: 0.025-0.127 mm (0.001-0.005 in). Indexing is used to achieve the best possible match of high spots to low spots between related components. Refer to Brake Rotor Assembled Lateral Runout Correction - Indexing . See: Brake Rotor Assembled Lateral Runout Correction - Indexing * The correction plate method of correcting assembled LRO involves the addition of a tapered plate between the brake rotor and the hub/axle flange. The correction plate method can be used to correct LRO that exceeds the specification by up to 0.23 mm (0.009 in). Refer to Brake Rotor Assembled Lateral Runout Correction - Correction Plates . See: Brake Rotor Assembled Lateral Runout Correction - Correction Plates * The on-vehicle brake lathe method is used to bring the LRO to within specifications through compensating for LRO while refinishing the brake rotor. Refer to Brake Rotor Assembled Lateral Runout Correction - On Vehicle Lathe . See: Brake Rotor Assembled Lateral Runout Correction On Vehicle Lathe If the assembled LRO cannot be corrected using these methods, then other components must be suspected as causing and/or contributing to the LRO concern.

Important: * The disc brake rotors do not require refinishing as part of routine brake system service. New disc brake rotors do not require refinishing. Do not refinish disc brake rotors in an attempt to correct the following conditions: - Brake system noise - squeal, growl, groan - Uneven and/or premature disc brake pad wear - Superficial or cosmetic corrosion/rust of the disc brake rotor friction surface - Scoring of the disc brake rotor friction surface less than the maximum allowable specification * Before refinishing a brake rotor, the rotor MUST first be checked for adequate thickness to allow the rotor to be refinished and remain above the minimum allowable thickness after refinish specification. Disc brake rotors should only be refinished if they have adequate thickness to be refinished and if one or more of the following conditions exist: - Thickness variation in excess of the maximum allowable specification - Excessive corrosion/rust and/or pitting - Cracks and/or heat spots - Excessive blueing discoloration - Scoring of the disc brake rotor surface in excess of the maximum allowable specification * Disc brake rotors may need to be refinished as part of the process for correcting brake rotor assembled lateral runout (LRO) that exceeds the maximum allowable specification. Important: If the vehicle is equipped with cross-drilled rotors, use a lathe with positive rake tooling. This setup requires less cutting pressure, which will result in less vibration, and a better surface finish. Also, use a vibration dampener when cutting. Otherwise, refinish according to the following instructions. Important: Whenever the brake rotor has been separated from the hub/axle flange, clean any rust or contaminants from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in increased assembled lateral runout (LRO) of the brake rotor, which could lead to brake pulsation. 1. Using the J 42450-A , thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange. 2. Using the J 41013 , thoroughly clean any rust or corrosion from the mating surface and mounting surface of the brake rotor. 3. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining. 4. Mount the brake rotor to the brake lathe according to the lathe manufacturer's instructions, ensuring that all mounting attachments and adapters are clean and free of debris. 5. Ensure that any vibration dampening attachments are securely in place. 6. With the brake lathe running, slowly bring in the cutting tools until they just contact the brake rotor friction surfaces. 7. Observe the witness mark on the brake rotor. If the witness mark extends approximately three-quarters or more of the way around the brake rotor friction surface on each side, the brake rotor is properly mounted to the lathe. 8. If the witness mark does not extend three-quarters or more of the way around the brake rotor, re-mount the rotor to the lathe. 9. Following the brake lathe manufacturer's instructions, refinish the brake rotor. 10. After each successive cut, inspect the brake rotor thickness. 11. If at any time the brake rotor exceeds the minimum allowable thickness after refinish specification, the brake rotor must be replaced. 12. After refinishing the brake rotor, use the following procedure in order to obtain the desired non-directional finish: Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Service and Repair > Procedures > Page 11395 1. Follow the brake lathe manufacturer's recommended speed setting for applying a non-directional finish. 2. Using moderate pressure, apply the non-directional finish: * If the lathe is equipped with a non-directional finishing tool, apply the finish with 120-grit aluminum oxide sandpaper. * If the lathe is not equipped with a non-directional finishing tool, apply the finish with a sanding block and 150-grit aluminum oxide sandpaper. 3. After applying a non-directional finish, clean each friction surface of the brake rotor with denatured alcohol, or an equivalent approved brake cleaner. 13. Remove the brake rotor from the brake lathe. 14. Measure the assembled LRO of the brake rotor to ensure optimum performance of the disc brakes. 15. If the brake rotor assembled LRO measurement exceeds the specification, bring the LRO to within specifications.

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice . Important: Before performing the antilock brake system (ABS) Automated Bleed Procedure, first perform a manual or pressure bleed of the base brake system. The automated bleed procedure is recommended when one of the following conditions exist: * Base brake system bleeding does not achieve the desired pedal height or feel * Extreme loss of brake fluid has occurred * Air ingestion is suspected in the secondary circuits of the brake modulator assembly The ABS Automated Bleed Procedure uses a scan tool to cycle the system solenoid valves and run the pump in order to purge any air from the secondary circuits. These circuits are normally closed off, and are only opened during system initialization at vehicle start up and during ABS operation. The automated bleed procedure opens these secondary circuits and allows any air trapped in these circuits to flow out toward the brake corners. Automated Bleed Procedure Notice: The Auto Bleed Procedure may be terminated at any time during the process by pressing the EXIT button. No further Scan Tool prompts pertaining to the Auto Bleed procedure will be given. After exiting the bleed procedure, relieve bleed pressure and disconnect bleed equipment per manufacturers instructions.

This bulletin should be read by all parties involved in KeyCode activity, including dealer operator, partner security coordinator, sales, service and parts departments. A copy of this bulletin should be printed and maintained in the parts department for use as a reference. Important U.S. dealers should refer to Corporate Bulletin Number 10-00-89-009. Where Are Key Codes Located? General Motors provides access to KeyCodes through three sources when a vehicle is delivered to a dealer. Vehicle KeyCodes are located on the original vehicle invoice to the dealership. There is a small white bar coded tag sent with most new vehicles that also has the key code printed on it. Dealerships should make a practice of comparing the tag's keycode numbers to the keycode listed on the invoice. Any discrepancy should be reported immediately to the GM of Canada Key Code Inquiry Desk. Remember to remove the key tag prior to showing vehicles to potential customers. The third source for Key codes is through the GM KeyCode Look-Up feature within the OEConnection D2DLink application. KeyCode Look-Up currently goes back 17 previous model years from the current model year. When a vehicle is received by the dealership, care should be taken to safeguard the original vehicle invoice and KeyCode tag provided with the vehicle. Potential customers should not have access to the invoice or this KeyCode tag prior to the sale being completed. After a sale has been completed, the KeyCode information belongs to the customer and General Motors. Tip Only the original invoice contains key code information, a re-printed invoice does not. GM KeyCode Look-Up Application for GM of Canada Dealers All dealers should review the General Motors of Canada KeyCode Look-Up Policies and Procedures (Service Policy & Procedures Manual Section 3.1.6 "Replacement of VIN plates & keys"). Please note that the KeyCode Access site is restricted. Only authorized users should be using this application. Please see your Parts Manager for site authorized users. KeyCode Look-Up currently goes back 17 years from current model year. Important notes about security: - Users may not access the system from multiple computers simultaneously. - Users may only request one KeyCode at a time. - KeyCode information will only be available on the screen for 2 minutes. - Each user is personally responsible for maintaining and protecting their password. - Never share your password with others. - User Id's are suspended after 6 consecutive failed attempts. - User Id's are disabled if not used for 90 days. - Processes must be in place for regular dealership reviews. - The Parts Manager (or assigned management) must have processes in place for employee termination or life change events. Upon termination individuals access must be turned off immediately and access should be re-evaluated upon any position changes within the dealership. - If you think your password or ID security has been breached, contact Dealer Systems Support at 1-800-265-0573. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Starting System > Key > Component Information > Technical Service Bulletins > Locks - Key Code Security Rules and Information > Page 11701 Each user will be required to accept the following agreement each time the KeyCode application is used. Key Code User Agreement - Key codes are proprietary information belonging to General Motors Corporation and to the vehicle owner. - Unauthorized access to, or use of, key code information is unlawful and may subject the user to criminal and civil penalties. - This information should be treated as strictly confidential and should not be disclosed to anyone unless authorized. I will ensure that the following information is obtained prior to releasing any Key Code information: 1. Government issued picture ID (Drivers License) 2. Registration or other proof of ownership. Registration should have normal markings from the Province that issued the registration and possibly the receipt for payment recorded as well. Important - GM takes this agreement seriously. Each user must be certain of vehicle ownership before giving out key codes. - When the ownership of the vehicle is in doubt, dealership personnel should not provide the information. Key code requests should never be received via a fax or the internet and key codes should never be provided to anyone in this manner. A face to face contact with the owner of the vehicle is the expected manner that dealers will use to release a key code or as otherwise stipulated in this bulletin or other materials. - Key codes should NEVER be sent via a fax or the internet. - Each Dealership should create a permanent file to document all KeyCode Look Up transactions. Requests should be filed by VIN and in each folder retain copies of the following: - Government issued picture ID (Drivers License) - Registration or other proof of ownership. - Copy of the paid customer receipt which has the name of the employee who cut and sold the key to the customer. - Do not put yourself or your Dealership in the position of needing to "explain" a KeyCode Look Up to either GM or law enforcement officials. - Dealership Management has the ability to review all KeyCode Look-Up transactions. - Dealership KeyCode documentation must be retained for two years. Frequently Asked Questions (FAQs) for GM of Canada Dealers How do I request a KeyCode for customer owned vehicle that is not registered? Scrapped, salvaged or stored vehicles that do not have a current registration should still have the ownership verified by requesting the vehicle title, current insurance policy and / or current lien holder information from the customers financing source. If you cannot determine if the customer is the owner of the vehicle, do not provide the key code information. In these cases, a short description of the vehicle (scrapped, salvaged, etc.) and the dealership location should be kept on file. Any clarifying explanation should be entered into the comments field. How do I document a KeyCode request for a vehicle that is being repossessed? The repossessor must document ownership of the vehicle by providing a court ordered repossession order and lien-holder documents prior to providing key code information. Copies of the repossessors Drivers License and a business card should be retained by the dealership for documentation. What do I do if the registration information is locked in the vehicle? Every effort should be made to obtain complete information for each request. Each Dealership will have to decide on a case by case basis if enough information is available to verify the customer's ownership of the vehicle. Other forms of documentation include vehicle title, insurance policy, and or current lien information from the customers financing source. Dealership Management must be involved in any request without complete information. If you cannot determine if the customer is the owner of the vehicle, do not provide the key code information. Can I get a print out of the information on the screen? It is important to note that the Key Code Look Up Search Results contain sensitive and/or proprietary information. For this reason GM recommends against printing it. If the Search Results must be printed, store and/or dispose of the printed copy properly to minimize the risk of improper or illegal use. Who in the dealership has access to the KeyCode application? Dealership Parts Manager (or assigned management) will determine, and control, who is authorized to access the KeyCode Look Up application. However, we anticipate that dealership parts and service management will be the primary users of the application. The KeyCode Look Up application automatically tracks each user activity session. Information tracked by the system includes: User name, User ID, all other entered data and the date/time of access. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Starting System > Key > Component Information > Technical Service Bulletins > Locks - Key Code Security Rules and Information > Page 11702 What if I input the VIN incorrectly? If an incorrect VIN is entered into the system (meaning that the system does not recognize the VIN or that the VIN has been entered incorrectly) the system will return an error message. If I am an authorized user for the KeyCode application, can I access the application from home? Yes. What if I suspect key code misuse? Your dealership should communicate the proper procedures for requesting key codes. Any suspicious activity either within the dealership or externally should be reported to Dealer Systems Support at 1-800-265-0573 or GM of Canada Key Code Inquiry Desk at 1-905-644-4892. Whose key codes can I access through the system? At this time the following Canadian vehicle codes are available through the system: Chevrolet, Cadillac, Buick, Pontiac, GMC, HUMMER (H2 and H3 only), Oldsmobile, Saturn, Saab and Isuzu (up to 2002 model year) for a maximum of 17 model years. What should I do if I enter a valid VIN and the system does not produce any key code information? Occasionally, the KeyCode Look Up application may not produce a key code for a valid VIN. This may be the result of new vehicle information not yet available. In addition, older vehicle information may have been sent to an archive status. If you do not receive a key code returned for valid VIN, you should contact GM of Canada Key Code Inquiry Desk at 1-905-644-4892. How do I access KeyCodes if the KeyCode Look-up system is down? If the KeyCode Look-up system is temporarily unavailable, you can contact the original selling dealer who may have it on file or contact GM of Canada Key Code Inquiry Desk at 1-905-644-4892. If the customer is dealing with an emergency lock-out situation, you need to have the customer contact Roadside assistance, OnStar if subscribed, or 911. What should I do if the KeyCode from the look-up system does not work on the vehicle? On occasion a dealer may encounter a KeyCode that will not work on the vehicle in question. In cases where the KeyCode won't work you will need to verify with the manufacturer of the cutting equipment that the key has been cut correctly. If the key has been cut correctly you may be able to verify the proper KeyCode was given through the original selling dealer. When unable to verify the KeyCode through the original selling dealer contact GM of Canada Key Code Inquiry Desk at 1-905-644-4892. If the key has been cut correctly and the code given does not work, the lock cylinder may have been changed. In these situations following the proper SI document for recoding a key or replacing the lock cylinder may be necessary. How long do I have to keep KeyCode Records? Dealership KeyCode documentation must be retained for two years. Can I get a KeyCode changed in the Look-Up system? Yes, KeyCodes can be changed in the Look-Up system if a lock cylinder has been changed. Contact GM of Canada Key Code Inquiry Desk at 1-905-644-4892. What information do I need before I can provide a driver of a company fleet vehicle Keys or KeyCode information? The dealership should have a copy of the individual's driver's license, proof of employment and registration. If there is any question as to the customer's employment by the fleet company, the dealer should attempt to contact the fleet company for verification. If there is not enough information to determine ownership and employment, this information should not be provided. How do I document a request from an Independent Repair facility for a KeyCode or Key? The independent must provide a copy of their driver's license, proof of employment and signed copy of the repair order for that repair facility. The repair order must include customer's name, address, VIN, city, province and license plate number. Copies of this information must be included in your dealer KeyCode file.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11776 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11777 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11778 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11779 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11780 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11781 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11782 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11783 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11784 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11785 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11849 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11850 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 11851 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing.

Correction Technicians are to install a noise suppression filter, P/N 1224205, into the OnStar(R) battery voltage circuit, a few centimeters (inches) from the VCIM. The filter package has three attached wires - a single yellow wire at one end with a yellow wire and a black wire at the other. Install the single yellow wire side into the battery voltage circuit towards the VCIM. Install the remaining single yellow wire into the battery voltage circuit toward the fuse and the black wire to ground. Important The noise suppression filter is polarity sensitive. The filter is designed to be most effective when the end with the capacitor ground is connected towards the source of the electrical noise. Install the filter in this polarity first. If the noise level is still not satisfactory, try disconnecting the capacitor ground. In some cases, if the first installation does not correct the noise, try reversing the filter polarity (removing the filter, turning it end for end and then reinstalling it) and grounding the capacitor lead.

In two cases, these fuses have not provided protection for the wiring system of the vehicles they were customer installed in. Upon testing the 15 amp version, it was found that the fuse still would not "open" when shorted directly across the battery terminals. How to Identify These Fuses Packed in a 120 piece set, the fuse has a translucent, hard plastic, blue body with the amperage stamped into the top. There are no white painted numbers on the fuse to indicate amperage. There are no identifying marks on the fuse to tell who is making it. The fuses are known to be distributed by Harbor Freight Tools but there may be other marketers, and packaging of this style of fuse. It would be prudent to replace these fuses if found in a customers vehicle. Likewise, if wiring overheating is found you should check the fuse panel for the presence of this style of fuse. All GM dealers should use genuine GM fuses on the vehicles they service. You should also encourage the use of GM fuses to your customers to assure they are getting the required electrical system protection. GM has no knowledge of any concerns with other aftermarket fuses. If additional information becomes available, this bulletin will be updated.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11911 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11912 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11913 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11914 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11915 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11916 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11917 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11918 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11919 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11920 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11984 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11985 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 11986 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12014 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12015 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12016 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12017 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12018 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12019 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12020 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12021 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12022 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12023 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12087 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12088 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12089 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing.

A light coating on the terminal surfaces is sufficient to correct the condition. Supercede: This bulletin is being revised to update the Attention statement and add the 2011 model year. Please discard Corporate Bulletin Number 09-06-03-004C (Section 06 Engine/Propulsion System). Condition Some customers may comment on any of the following conditions: - An intermittent no crank/no start - Intermittent malfunction indicator lamp (MIL) illumination - Intermittent service lamp illumination - Intermittent service message(s) being displayed The technician may determine that he is unable to duplicate the intermittent condition. Cause This condition may be caused by a buildup of nonconductive insulating oxidized debris known as fretting corrosion, occurring between two electrical contact surfaces of the connection or connector. This may be caused by any of the following conditions: - Vibration - Thermal cycling - Poor connection/terminal retention - Micro motion - A connector, component or wiring harness not properly secured resulting in movement On low current signal circuits this condition may cause high resistance, resulting in intermittent connections. On high current power circuits this condition may cause permanent increases in the resistance and may cause a device to become inoperative. Representative List of Control Modules and Components The following is only a representative list of control modules and components that may be affected by this connection or connector condition and DOES NOT include every possible module or component for every vehicle. - Blower Control Module - Body Control Module (BCM) - Communication Interface Module (CIM) - Cooling Fan Control Module - Electronic Brake Control Module (EBCM) - Electronic Brake and Traction Control Module (EBTCM) - Electronic Suspension Control (ESC) Module - Engine Control Module (ECM) - Heating, Ventilation and Air Conditioning (HVAC) Control Module Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Starting and Charging > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Customer Interest: > 09-06-03-004D > Dec > 10 > Electrical - MIL ON/DTC's Set By Various Control Modules > Page 12265 - HVAC Actuator - Inflatable Restraint Sensing and Diagnostic Module (SDM) - Any AIR BAG module - Seatbelt Lap Anchor Pretensioner - Seatbelt Retractor Pretensioner - An SIR system connection or connector condition resulting in the following DTCs being set: B0015, B0016, B0019, B0020, B0022, or B0023 - Powertrain Control Module (PCM) - Remote Control Door Lock Receiver (RCDLR) - Transmission Control Module (TCM) Correction Important DO NOT replace the control module, wiring or component for the following conditions: - The condition is intermittent and cannot be duplicated. - The condition is present and by disconnecting and reconnecting the connector the condition can no longer be duplicated. Use the following procedure to correct the conditions listed above. 1. Install a scan tool and perform the Diagnostic System Check - Vehicle. Retrieve and record any existing history or current DTCs from all of the control modules (refer to SI). ‹› If any DTC(s) are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle to identify the connector(s) of the control module/component which may be causing the condition (refer to SI). ‹› If DTCs are not set, refer to Symptoms - Vehicle to identify the connector(s) of the control module/component which may be causing the condition (refer to SI). 2. When identified, use the appropriate DTC Diagnostics, Symptoms, Schematics, Component Connector End Views and Component Locator documents to locate and disconnect the affected harness connector(s) which are causing the condition. Note Fretting corrosion looks like little dark smudges on electrical terminals and appear where the actual electrical contact is being made. In less severe cases it may be unable to be seen or identified without the use of a magnifying glass. Important DO NOT apply an excessive amount of dielectric lubricant to the connectors as shown, as hydrolock may result when attempting to mate the connectors.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12334 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12335 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12336 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12337 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12338 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12339 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12340 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12341 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12342 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12343 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12361 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors.

The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12362 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12407 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12408 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12409 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Follow the specific procedures and instructions when working with the SIR/SRS, and the wiring components, such as connectors and terminals. IMPORTANT: Do not use the terminals in the kit in order to replace damaged SIR/SRS system terminals. Use either an SIR/SRS pigtail or a terminated lead from the SIR Repair Kit Tray. The tool kit J-38125 contains the following items: - DuraSeal splice sleeves, in order to repair the SIR/SRS wiring - A special crimping tool - A heat torch - An instruction manual The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides the necessary low resistance contact integrity for these sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors SIR/SRS CONNECTOR REPAIR (PLASTIC BODY AND TERMINAL METAL PIN) The terminals in the SIR/SRS system are made with a special plating. This plating provides the necessary contact integrity for the sensitive, low energy circuits. Use the J-38125 SIR/SRS Terminal Repair Kit for repairing SIR/SRS terminals and connectors. Do not substitute any other terminals for those in the repair kit. The J-38125 SIR/SRS Terminal Repair Kit contains: Various terminated leads for sensing and diagnostic module (SDM) terminal replacement - Various connector positive assurance (CPA) locks for SIR/SRS connectors - Base of steering column pigtail connectors part number 12085514 - Yellow vinyl electrical tape Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12413 Pigtail repair packs are available for SIR/SRS connectors with eight or less terminals. Only the connector body is available for connectors with more than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the connector body. SIR/SRS COMPONENT WIRE PIGTAIL REPAIR IMPORTANT: Do not make wire, connector, or terminal repairs on components with wire pigtails. A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component, with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component. SIR/SRS WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the DuraSeal splice sleeves. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except tefzel and coaxial. - Do not use the crimp and DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12414 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12416 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12417 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 12418 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise.

In two cases, these fuses have not provided protection for the wiring system of the vehicles they were customer installed in. Upon testing the 15 amp version, it was found that the fuse still would not "open" when shorted directly across the battery terminals. How to Identify These Fuses Packed in a 120 piece set, the fuse has a translucent, hard plastic, blue body with the amperage stamped into the top. There are no white painted numbers on the fuse to indicate amperage. There are no identifying marks on the fuse to tell who is making it. The fuses are known to be distributed by Harbor Freight Tools but there may be other marketers, and packaging of this style of fuse. It would be prudent to replace these fuses if found in a customers vehicle. Likewise, if wiring overheating is found you should check the fuse panel for the presence of this style of fuse. All GM dealers should use genuine GM fuses on the vehicles they service. You should also encourage the use of GM fuses to your customers to assure they are getting the required electrical system protection. GM has no knowledge of any concerns with other aftermarket fuses. If additional information becomes available, this bulletin will be updated.

Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12469 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12470 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12471 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12472 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12473 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12474 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12475 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12476 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12477 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12478 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12542 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12543 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12544 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12545 1. IMPORTANT: You must perform the following procedures in the order listed. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip keeping all of the wire strands intact. Open the harness by removing any tape. 2. Use a sewing seam ripper, available from sewing supply stores, in order to cut open the harness in order to avoid wire insulation damage. 3. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 4. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent american wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 5. Slide a section of high temperature SCT1 shrink tubing down the length of wire to be spliced. Ensure that the shrink tubing will not interfere with the splice procedure. 6. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 7. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 8. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 9. Insert the wire into the DuraSeal splice sleeve barrel until the wire hits the barrel stop. 10. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice.

Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12551 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12552 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 12553 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12572 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12573 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12574 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4.

Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12576 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12577 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12578 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12579 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12580 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12581 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12599 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12600 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12645 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12646 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12647 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing.

You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent AWG size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12652 5. Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12654 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12655 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 12656 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes.

Electrical Ground Repair Overview Proper electrical system function relies on secure, stable and corrosion-free electrical ground connections. Loose, stripped, or corroded connections increase the possibility of improper system function and loss of module communication. These conditions may also lead to unnecessary repairs and component replacement. In general, electrical ground connections are accomplished using one, or a combination of the following attachment methods: - Welded M6 stud and nut - Welded M6 nut and bolt - Welded M8 nut and bolt Determine which attachment method is used and perform the appropriate or alternative repair as described in this bulletin. M6 Weld Stud Replacement Caution Use only the GM-approved replacement fasteners with conductive finish for electrical ground repair. 1. Select a location adjacent the damaged or missing M6 ground stud having 20 mm (0.79 in) clearance behind the panel surface and 20 mm (0.79 in) clearance surrounding the M6 conductive rivet stud flange. 2. Using GM approved residue-free solvent or equivalent, remove any grease from the repair site and allow to dry. Note Ensure 20 mm (0.79 in) clearance is maintained behind the panel to be drilled. 3. Drill a 10 mm (0.40 in) diameter hole through the panel. 4. Remove paint and primer from the area surrounding the 10 mm (0.40 in) hole until bare metal is visible.

PLEASE FAMILIARIZE YOURSELF WITH THESE UPDATES BEFORE PERFORMING YOUR NEXT GM WHEEL ALIGNMENT SERVICE. Please discard Corporate Bulletin Number 05-03-07-009B (Section 03 - Suspension). Purpose The purpose of this bulletin is to provide retail, wholesale and fleet personnel with General Motors' warranty service requirements and recommendations for customer concerns related to wheel alignment. For your convenience, this bulletin updates and centralizes all of GM's Standard Wheel Alignment Service Procedures, Policy Guidelines and bulletins on wheel alignment warranty service. Important PLEASE FAMILIARIZE YOURSELF WITH THESE UPDATES BEFORE PERFORMING YOUR NEXT GM WHEEL ALIGNMENT SERVICE. The following five (5) key steps are a summary of this bulletin and are REQUIRED in completing a successful wheel alignment service. 1. Verify the vehicle is in an Original Equipment condition for curb weight, tires, wheels, suspension and steering configurations. Vehicles modified in any of these areas are not covered for wheel alignment warranty. 2. Review the customer concern relative to "Normal Operation" definitions. 3. Verify that vehicle is within the "Mileage Policy" range. 4. Document wheel alignment warranty claims appropriately for labor operations E2000 and E2020. The following information must be documented or attached to the repair order: - Customer concern in detail - What corrected the customer concern? - If a wheel alignment is performed: - Consult SI for proper specifications. - Document the "Before" AND "After" wheel alignment measurements/settings. - Completed "Wheel Alignment Repair Order Questionnaire" (form attached to this bulletin) 5. Use the proper wheel alignment equipment (preferred with print-out capability), process and the appropriate calibration maintenance schedules. Important If it is determined that a wheel alignment is necessary under warranty, use the proper labor code for the repair. E2000 for Steering Wheel Angle and/or Front Toe set or E2020 for Wheel Alignment Check/Adjust includes Caster, Camber and Toe set (Wheel alignment labor time for other component repairs is to be charged to the component that causes a wheel alignment operation.). The following flowchart is to help summarize the information detailed in this bulletin and should be used whenever a wheel alignment is performed. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Steering/Suspension - Wheel Alignment Specifications > Page 12880 Verify Original Equipment Condition of the Vehicle - Verify that Original Equipment Tires and Wheels or Official GM Accessory Tires and Wheels are on the vehicle. - Verify that aftermarket suspension "Lift" or "Lowering" Kits or other suspension alterations have NOT been done to the vehicle. - Check for accidental damage to the vehicle; for example, severe pothole or curb impacts, collision damage that may have affected the wheel alignment of the vehicle; e.g., engine cradles, suspension control arms, axles, wheels, wheel covers, tires may show evidence of damage/impact. - Check to be sure vehicle has seen "Normal Use" rather than abuse; e.g., very aggressive driving may show up by looking at the tires and condition of the vehicle. - Check for other additional equipment items that may significantly affect vehicle mass such as large tool boxes, campers, snow plow packages (without the snowplow RPO), etc., especially in trucks and cutaway/incomplete vehicles. Significant additional mass can affect trim height and wheel alignment of the vehicle and may necessitate a customer pay wheel alignment when placed semi-permanently in the vehicle (Upfitter instructions are to realign the vehicle after placement of these types of items. (This typically applies to trucks and incomplete vehicles that can be upfit with equipment such as the above.) Customer Concerns, "Normal Operation" Conditions and "Mileage Policy" Possible Concerns The following are typical conditions that may require wheel alignment warranty service: 1. Lead/Pull: defined as "at a constant highway speed on a typical straight road, the amount of effort required at the steering wheel to maintain the vehicle's straight heading." Important Please evaluate for the condition with hands-on the steering wheel. Follow the "Vehicle Leads/Pulls" diagnostic tree located in SI to determine the cause of a lead/pull concern. Lead/Pull concerns can be due to road crown or road slope, tires, wheel alignment or even in rare circumstances a steering gear issue. Lead/pull concerns due to road crown are considered "Normal Operation" and are NOT a warrantable condition -- the customer should be advised that this is "Normal Operation." Important Some customers may comment on a "Lead/Pull" when they hold the steering wheel in a level condition. If so, this is more likely a "steering wheel angle" concern because the customer is "steering" the vehicle to obtain a "level" steering wheel. 2. Steering wheel angle to the left or right (counter-clockwise or clockwise, respectively): Defined as the steering wheel angle (clocking) deviation from "level" while maintaining a straight heading on a typical straight road. 3. Irregular or Premature tire wear: Slight to very slight "feathering" or "edge" wear on the shoulders of tires is NOT considered unusual and should even out with a tire rotation; if the customer is concerned about a "feathering" condition of the tires, the customer could be advised to rotate the tires earlier than the next scheduled mileage/maintenance interval (but no later than the next interval). Be sure to understand the customer's driving habits as this will also heavily influence the tire wear performance; tire wear from aggressive or abusive driving habits is NOT a warrantable condition. Important Slight or mild feathering, cupping, edge or heel/toe wear of tire tread shoulders is "normal" and can show up very early in a tire/vehicle service mileage; in fact, some new tires can show evidence of feathering from the factory. These issues do NOT affect the overall performance and tread life of the tire. Dealer personnel should always check the customer's maintenance records to ensure that tire inflation pressure is being maintained to placard and that the tires are being rotated (modified-X pattern) at the proper mileage intervals. Wheel alignments are NOT to be performed for the types of "Normal" Tire Feathering shown in Figures 1-4 below. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Steering/Suspension - Wheel Alignment Specifications > Page 12881 Figure 1: Full Tread View - "NORMAL" Tire "Feathering" Wear on the Shoulder/Adjacent/Center Ribs Figure 2: Tire Shoulder View Example 1 - "NORMAL" Tire "Feathering" Wear on the Shoulder Figure 3: Tire Shoulder View Example 2 - "NORMAL" Tire "Feathering" Wear Figure 4: Detail Side View of Tire Shoulder Area - "NORMAL" Tire "Feathering" Wear Important When a wheel alignment is deemed necessary for tire wear, be sure to document on the repair order, in as much detail as possible, the severity and type of tire wear (e.g., severe center wear or severe inside or outside shoulder wear) and the position of the tire on the vehicle (RF, LF, LR, RR). Please note the customer's concern with the wear such as, noise, appearance, wear life, etc. A field product report with pictures of the tire wear condition is recommended. Refer to Corporate Bulletin Number 02-00-89-002J and #07-00-89-036C. 4. Other repairs that affect wheel alignment; e.g., certain component replacement such as suspension control arm replacement, engine cradle adjustment/replace, steering gear replacement, steering tie rod replace, suspension strut/shock, steering knuckle, etc. may require a wheel alignment. Important If other components or repairs are identified as affecting the wheel alignment, policy calls for the wheel alignment labor time to be charged to the replaced/repaired component's labor operation time rather than the wheel alignment labor operations. Important Vibration type customer concerns are generally NOT due to wheel alignment except in the rare cases; e.g., extreme diagonal wear across the tread. In general, wheel alignments are NOT to be performed as an investigation/correction for vibration concerns. "Normal Operation" Conditions Vehicle Lead/Pull Due to Road Crown or Slope: As part of "Normal Operation," vehicles will follow side-to-side or left to right road crown or slope. Be sure to verify from the customer the types of roads they are driving as they may not recognize the influence of road crown on vehicle lead/pull and steering wheel angle. If a vehicle requires significant steering effort to prevent it from "climbing" the road crown there may be an issue to be looked into further. Important Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Steering/Suspension - Wheel Alignment Specifications > Page 12882 A wheel alignment will generally NOT correct vehicles that follow the road crown since this is within "Normal Operation." Mileage Policy The following mileage policy applies for E2020 and E2000 labor operations: Note Wheel Alignment is NOT covered under the New Vehicle Limited Warranty for Express and Savana Cutaway vehicles as these vehicles require Upfitters to set the wheel alignment after completing the vehicles. - 0-800 km (0-500 mi): E2000/E2020 claims ONLY allowed with Call Center Authorization. Due to the tie down during shipping, the vehicle's suspension requires some time to reach normal operating position. For this reason, new vehicles are generally NOT to be aligned until they have accumulated at least 800 km (500 mi). A field product report should accompany any claim within this mileage range. - 801-12,000 km (501-7,500 mi): - If a vehicle came from the factory with incorrect alignment settings, any resulting off-angle steering wheel, lead/pull characteristics or the rare occurrence of excessive tire wear would be apparent early in the life of the vehicle. The following policy applies: - Vehicles 100% Factory Set/Measured for Caster/Camber/Toe - Escalade/ESV/EXT, Tahoe/Suburban, Yukon/XL/Denali, Silverado/Sierra, Express/Savana, Corvette and Colorado/Canyon: E2000/E2020 Claims: Call Center Authorization Required - All Vehicles NOT 100% Factory Set/Measured for Caster/Camber/Toe as noted above: E2000/E2020 Claims: Dealer Service Manager Authorization Required - 12,001 km and beyond (7,501 miles and beyond): During this period, customers are responsible for the wheel alignment expense or dealers may provide on a case-by case basis a one-time customer enthusiasm claim up to 16,000 km (10,000 mi). In the event that a defective component required the use of the subject labor operations, the identified defective component labor operation will include the appropriate labor time for a wheel alignment as an add condition to the component repair. Important Only one wheel alignment labor operation claim (E2000 or E2020) may be used per VIN. Warranty Documentation Requirements When a wheel alignment service has been deemed necessary, the following items will need to be clearly documented on/with the repair order: - Customer concern in detail - What corrected the customer concern? - If a wheel alignment is performed: - Consult SI for proper specifications. - Document the "Before" AND "After" wheel alignment measurements/settings. - Completed "Wheel Alignment Repair Order Questionnaire" (form attached to this bulletin) 1. Document the customer concern in as much detail as possible on the repair order and in the warranty administration system. Preferred examples: - Steering wheel is off angle in the counterclockwise direction by approximately x degrees or clocking position. - Vehicle lead/pulls to the right at approximately x-y mph. Vehicle will climb the road crown. Severe, Moderate or Slight. - RF and LF tires are wearing on the outside shoulders with severe feathering. Important In the event of a lead/pull or steering wheel angle concern, please note the direction of lead/pull (left or right) or direction of steering wheel angle (clockwise or counterclockwise) on the repair order and within the warranty claim verbatim. Important In the event of a tire wear concern, please note the position on the vehicle and where the wear is occurring on the tire; i.e., the RF tire is wearing on the inside shoulder. 2. Document the technician's findings on cause and correction of the issue. Examples: - Reset LF toe from 0.45 degrees to 0.10 degrees and RF toe from -0.25 degrees to 0.10 degrees to correct the steering wheel angle from 5 degrees counterclockwise to 0 degrees. - Reset LF camber from 0.25 degrees to -0.05 degrees to correct the cross-camber condition of +0.30 degrees to 0.00 degrees on the vehicle. - Front Sum toe was found to be 0.50 degrees, reset to 0.20 degrees. 3. Print-out the "Before" and "After" wheel alignment measurements/settings and attach them to the Repair Order or if print-out capability is not Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Steering/Suspension - Wheel Alignment Specifications > Page 12883 available, measurements may also be clearly and legibly handwritten into the Wheel Alignment Repair Order Questionnaire attached to this bulletin. 4. Attach the Wheel Alignment Repair Order Questionnaire below along with the print-out of "Before" and "After" wheel alignment measurements to the Repair Order and retain for use by GM. Wheel Alignment Equipment and Process Wheel alignments must be performed with a quality machine that will give accurate results when performing checks. "External Reference" (image-based camera technology) is preferred. Please refer to Corporate Bulletin Number 05-00-89-029B: General Motors Dealership Critical Equipment Requirements and Recommendations. Requirements: - Computerized four wheel alignment system. - Computer capable of printing before and after alignment reports. - Computer capable of time and date stamp printout. - Racking system must have jacking capability - Racking system must be capable of level to 1.6 mm (1/16 in) - Appropriate wheel stops and safety certification - Built-in turn plates and slip plates - Wheel clamps capable of attaching to 20" or larger wheels - Racking capable of accepting any GM passenger car or light duty truck - Operator properly trained and ASE-certified (U.S. only) in wheel alignment Recommendations: Racking should have front and rear jacking capability. Equipment Maintenance and Calibration: Alignment machines must be regularly calibrated in order to give correct information. Most manufacturers recommend the following: - Alignment machines with "internal reference" sensors should be checked (and calibrated, if necessary) every six months. - Alignment machines with "external reference" (image-based camera technology) should be checked (and calibrated, if necessary) once a year. - Racks must be kept level to within 1.6 mm (1/16 in). - If any instrument that is part of the alignment machine is dropped or damaged in some way, check the calibration immediately. Check with the manufacturer of your specific equipment for their recommended service/calibration schedule. Wheel Alignment Process When performing wheel alignment measurement and/or adjustment, the following steps should be taken: Preliminary Steps: 1. Verify that the vehicle has a full tank of fuel (compensate as necessary). 2. Inspect the wheels and the tires for damage. 3. Inspect the tires for the proper inflation and irregular tire wear. 4. Inspect the wheel bearings for excessive play. 5. Inspect all suspension and steering parts for looseness, wear, or damage. 6. Inspect the steering wheel for excessive drag or poor return due to stiff or rusted linkage or suspension components. 7. Inspect the vehicle trim height. 8. Compensate for frame angle on targeted vehicles (refer to Wheel Alignment Specifications in SI). Satisfactory vehicle operation may occur over a wide range of alignment angles. However, if the wheel alignment angles are not within the range of specifications, adjust the wheel alignment to the specifications. Refer to Wheel Alignment Specifications in SI. Give consideration to excess loads, such as tool boxes, sample cases, etc. Follow the wheel alignment equipment manufacturer's instructions. Measure/Adjust: Important Prior to making any adjustments to wheel alignment on a vehicle, technicians must verify that the wheel alignment specifications loaded into their wheel alignment machine are up-to-date by comparing these to the wheel alignment specifications for the appropriate model and model year in SI. Using incorrect and/or outdated specifications may result in unnecessary adjustments, irregular and/or premature tire wear and repeat customer concerns Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Steering/Suspension - Wheel Alignment Specifications > Page 12884 Important When performing adjustments to vehicles requiring a 4-wheel alignment, set the rear wheel alignment angles first in order to obtain proper front wheel alignment angles. Perform the following steps in order to measure the front and rear alignment angles: 1. Install the alignment equipment according to the manufacturer's instructions. 2. Jounce the front and the rear bumpers 3 times prior to checking the wheel alignment. 3. Measure the alignment angles and record the readings. If necessary, adjust the wheel alignment to vehicle specification and record the before and after measurements. Refer to Wheel Alignment Specifications in SI. Important Technicians must refer to SI for the correct wheel alignment specifications. SI is the only source of GM wheel alignment specifications that is kept up-to-date throughout the year. Test drive vehicle to ensure proper repair.

Description Alignment: Description and Operation Caster Description Caster Description Caster Description Caster is the tilting of the uppermost point of the steering axis either forward or backward, when viewed from the side of the vehicle. A backward tilt is positive (+) and a forward tilt is negative (-). Caster influences directional control of the steering but does not affect the tire wear. Caster is affected by the vehicle height, therefore it is important to keep the body at its designed height. Overloading the vehicle or a weak or sagging rear spring will affect caster. When the rear of the vehicle is lower than its designated trim height, the front suspension moves to a more positive caster. If the rear of the vehicle is higher than its designated trim height, the front suspension moves to a less positive caster. With too little positive caster, steering may be touchy at high speed and wheel returnability may be diminished when coming out of a turn. If one wheel has more positive caster than the other, that wheel will pull toward the center of the vehicle. This condition will cause the vehicle to pull or lead to the side with the least amount of positive caster. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Alignment > System Information > Description and Operation > Caster Description > Page 12895 Alignment: Description and Operation Camber Description Camber Description Camber Description Camber is the tilting of the wheels from the vertical when viewed from the front of the vehicle. When the wheels tilt outward at the top, the camber is positive (+). When the wheel tilts inward at the top, the camber is negative (-). The amount of tilt is measured in degrees from the vertical. Camber settings influence the directional control and the tire wear. Too much positive camber will result in premature wear on the outside of the tire and cause excessive wear on the suspension parts. Too much negative camber will result in premature wear on the inside of the tire and cause excessive wear on the suspension parts. Unequal side-to-side camber of 1 degree or more will cause the vehicle to pull or lead to the side with the most positive camber. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Alignment > System Information > Description and Operation > Caster Description > Page 12896 Alignment: Description and Operation Toe Description Toe Description Toe Description Toe is a measurement of how much the front and/or rear wheels are turned in or out from a straight-ahead position. When the wheels are turned in, toe is positive (+). When the wheels are turned out, toe is negative (-). The actual amount of toe is normally only a fraction of a degree. The purpose of toe is to ensure that the wheels roll parallel. Toe also offsets the small deflections of the wheel support system that occur when the vehicle is rolling forward. In other words, with the vehicle standing still and the wheels set with toe-in, the wheels tend to roll parallel on the road when the vehicle is moving. Improper toe adjustment will cause premature tire wear and cause steering instability.

Setback is the amount that one wheel may be aligned behind the other wheel. Setback may be the result of a road hazard or a collision. The first clue is a caster difference from side-to-side of more than 1 degree.

The first clue is a caster difference from side-to-side of more than 1 degree. Thrust Angles Description Thrust Angles Description Thrust Angles Description The front wheels aim or steer the vehicle. The rear wheels control tracking. This tracking action relates to the thrust angle (3). The thrust angle is the path that the rear wheels take. Ideally, the thrust angle is geometrically aligned with the body centerline (2). In the illustration, toe-in is shown on the left rear wheel, moving the thrust line (1) off center. The resulting deviation from the centerline is the thrust angle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Alignment > System Information > Description and Operation > Caster Description > Page 12900 If the thrust angle is not set properly the vehicle may "dog track", the steering wheel may not be centered or it could be perceived as a bent axle. Thrust angle can be checked during a wheel alignment. Positive thrust angle means the thrust line is pointing to the right hand side (RHS) of the vehicle. Negative thrust angle means the thrust line is pointing to the left hand side (LHS) of the vehicle. If the thrust angle is out of specification, moving the axle to body relationship will change the thrust angle reading. If the vehicle is out in the Positive (+) direction-moving the RHS forward and/or LHS rearward will move the thrust angle towards zero degrees. If the vehicle is out in the Negative (-) direction-moving the RHS rearward and/or LHS forward will move the thrust angle towards zero degrees. Lead/Pull Description Lead/Pull Description At a constant highway speed on a typical straight road, lead/pull is the amount of effort required at the steering wheel to maintain the vehicle's straight path. Important: Vehicles will tend to lead/pull in the direction of the road slope as part of normal operation. Lead/pull is usually caused by the following factors: * Road slope * Variability in tire construction * Wheel alignment (front cross caster and camber) * Unbalanced steering gear * Electronic Power Steering (EPS) steering position and torque sensors not calibrated correctly, if equipped. Torque Steer Description Torque Steer Description A vehicle pulls or leads in one direction during hard acceleration. A vehicle pulls or leads in the other direction during deceleration. The following factors may cause torque steer to be more apparent on a particular vehicle: * A slightly smaller diameter tire on the right front increases a right torque lead. Inspect the front tires for differences in the brand, the construction, or the size. If the tires appear to be similar, change the front tires from side-to-side and retest the vehicle. Tire and wheel assemblies have the most significant effect on torque steer correction. * A large difference in the right and left front tire pressure * Left-to-right differences in the front view axle angle may cause significant steering pull in a vehicle. The pull will be to the side with the most downward sloping axle from the differential to the wheels. Axles typically slope downward from the differential. The slope of the transaxle pan to Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Alignment > System Information > Description and Operation > Caster Description > Page 12901 level ground may be used as an indication of bias axle angles. The side with the higher transaxle pan (shown on the left side of the illustration) has the most downward sloping axle angle. Memory Steer Description Memory Steer Description Memory steer is when the vehicle wants to lead or pull in the direction the driver previously turned the vehicle. Additionally, after turning in the opposite direction, the vehicle will want to lead or pull in that direction. Wander Description Wander Description Wander is the undesired drifting or deviation of a vehicle to either side from a straight path with hand pressure on the steering wheel. Wander is a symptom of the vehicle's sensitivity to external disturbances, such as road crown and crosswind, and accentuated by poor on-center steering feel. Scrub Radius Description Scrub Radius Description Ideally, the scrub radius is as small as possible. Normally, the SAI angle and the centerline of the tire and the wheel intersect below the road surface, causing a positive scrub radius. With struts, the SAI angle is much larger than the long arm/short arm type of suspension. This allows the SAI angle to intersect the camber angle above the road surface, forming a negative scrub radius. The smaller the scrub radius, the better the directional stability. Installing aftermarket wheels that have additional offset will dramatically increase the scrub radius. The newly installed wheels may cause the centerline of the tires to move further away from the spindle. This will increase the scrub radius. A large amount of scrub radius can cause severe shimmy after hitting a bump. Four-wheel drive vehicles with large tires use a steering damper to compensate for an increased scrub radius. Scrub radius is not directly measurable by the conventional methods. Scrub radius is projected geometrically by engineers during the design phase of the suspension. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Alignment > System Information > Description and Operation > Page 12902 Alignment: Testing and Inspection Trim Height Inspection Trim Height Measurement Trim height is a predetermined measurement relating to vehicle ride height. Incorrect trim heights can cause the vehicle to bottom out over bumps, damage to the suspension components and symptoms similar to wheel alignment problems. Check the trim heights when diagnosing suspension concerns and before checking the wheel alignment. Perform the following before measuring the trim heights: * Set the tire pressure to the specifications shown on the certification label. Refer to Vehicle Certification, Tire Place Card, Anti-Theft, and Service Parts ID Label. * Check the fuel level. Add additional weight if necessary to simulate a full tank. * Make sure the passenger and rear compartments are empty, except for the spare tire. * Make sure the vehicle is on a flat and level surface, such as an alignment rack. * Check that all the vehicle doors are securely closed. * Check that the vehicle hood and rear deck lids are securely closed. * Check for installed after market accessories or modifications that could affect trim height measurement. Important: All dimensions are measured vertical to the ground. Trim height should be within ±22.0 mm (±0.87 in) to be considered correct. Measuring the Bumper Heights Use the following procedure to check the front bumper height: 1. Jounce the front and rear of the vehicle a few times and allow the suspension to settle. 2. The front bumper height measurement is taken outward 390 mm (15.35 in) from the center of the fascia to ground level. Measurements are made from the inner bumper core to ground level. Measure both sides and average the measurements. 3. Compare the measurement to the front bumper curb height specification. Refer to Trim Height Specifications. 4. If the measurement is outside of the specified range, replace the front springs. Refer to Strut, Strut Component and/or Spring Replacement. 5. Using your hands, lift the rear bumper approximately 38 mm (1.59 in). 6. Gently remove your hands and allow the vehicle to lower. 7. Using your hands, jounce the rear of the vehicle downward approximately 38 mm (1.59 in). 8. Gently remove your hands and allow the vehicle to rise. 9. The rear bumper height measurement is taken outward 530 mm (20.86 in) from the center of the fascia to ground level. Measurements are made from the inner bumper core to ground level. Measure both sides and average the measurements. 10. Compare the measurement to the rear bumper curb height specification. Refer to Trim Height Specifications. 11. If the measurement is outside of the specified range, replace the rear springs. Refer to Coil Spring Replacement.

Return rates ran as high as 60% with the TPM sensors still attached. Operational TPM sensors should not be returned to GM and are to be transferred to replacement wheels if they become necessary. Important: Operational TPM Sensors that are returned under warranty to General Motors will be charged back to the dealer.Sensors have a 10 year /150,000 mile (240,000 km) battery life, and should be transferred if one or more wheels are replaced. TPM Valve Stem / Grommet (0-ring) Replacement When the TPM sensors are transferred to new wheels you should replace the component used to seal the TPM sensor stem to the wheel. On sensors with an aluminum stem and visible nut on the outside of the wheel a replacement grommet (0-ring) should be used to assure a proper seal. The sensor retaining nut (except Aveo) should be tightened to 7 N.m (62 lb in) for all vehicles except Pontiac Vibe (4.0 N.m (35.4 lb in)). Important: ^ DO NOT overtorque the retaining nut. Notice: ^ Factory installed TPM Sensors come with plastic aluminum or nickel-plated brass stem caps. These caps should not be changed. Chrome plated steel caps may cause corrosion of aluminum valve stems due to incompatibility of the metals. On current style sensors the entire rubber stem is replaceable. The service interval on the revised TPM sensor with replaceable stem is the same as for any other traditional valve stem. Replace the stem at the time of tire replacement sensor transfer or whenever air seepage is suspected at the valve stem. When replacing the valve stem tighten the screw to 1.3 N.m (11.5 lb in). For either style of TPM sensor see the service parts guide for the correct GM part numbers to order and use.

On sensors with an aluminum stem and visible nut on the outside of the wheel a replacement grommet (0-ring) should be used to assure a proper seal. The sensor retaining nut (except Aveo) should be tightened to 7 N.m (62 lb in) for all vehicles except Pontiac Vibe (4.0 N.m (35.4 lb in)). Important: ^ DO NOT overtorque the retaining nut. Notice: ^ Factory installed TPM Sensors come with plastic aluminum or nickel-plated brass stem caps. These caps should not be changed. Chrome plated steel caps may cause corrosion of aluminum valve stems due to incompatibility of the metals. On current style sensors the entire rubber stem is replaceable. The service interval on the revised TPM sensor with replaceable stem is the same as for any other traditional valve stem. Replace the stem at the time of tire replacement sensor transfer or whenever air seepage is suspected at the valve stem. When replacing the valve stem tighten the screw to 1.3 N.m (11.5 lb in). For either style of TPM sensor see the service parts guide for the correct GM part numbers to order and use.

When dismounting and mounting tires, care must be taken when breaking the bead loose from the wheel. If the tire machines bead breaking fixture is positioned too close to the tire pressure sensor, as the tire bead breaks away from the wheel it may be forced into, or catch on the edge of the tire pressure sensor. This can damage the sensor and require the sensor to be replaced. Care must also be taken when transferring the tire bead to the other side of the wheel rim. As the tire machine rotates and the tire bead is stretched around the wheel rim, the bead can come in contact with the sensor if it is not correctly positioned in relation to the mounting/dismounting head prior to tire mounting/dismounting. This can also cause sensor damage requiring replacement. Procedure Notice: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result. Notice: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel. 1. Remove the valve core from the valve stem. 2. Deflate the tire completely. Important: Rim-clamp European-type tire changers are recommended. 3. Use the tire changer in order to remove the tire from the wheel. Follow steps 4-7 to remove the tire from the wheel. 4. When separating the tire bead from the wheel position the bead breaking fixture 90, 180 and 270 degrees from the valve stem.

Position the wheel and tire so the valve stem is situated at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the outer tire bead up and over the mounting/dismounting head. 6. Position the wheel and tire so that the valve stem is situated again at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the inner tire bead up and over the mounting/dismounting head. 7. Remove all residual liquid sealant from the inside of the tire and wheel surfaces. If any tire sealant is noted upon tire dismounting on vehicles equipped with TPM replace the tire pressure sensor. 8. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats. Important: If bead seat corrosion has been identified as an air loss concern on the wheel being worked on, refer to GM Service Bulletin # 08-03-10-006 for additional information on correcting the leak. 9. Apply GM P/N 12345884 (in Canada, P/N 5728223) or equivalent to the tire bead and the wheel rim.

Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim. 11. Position the rim so that the valve stem (1) is situated at the 3 o'clock position relative to the head (2). This will protect the sensor when the bottom bead seats. 12. After the bottom bead is on the wheel, reposition the wheel and tire so that the valve stem is situated at the 9 o'clock position relative to the head. This will protect the sensor while mounting the tire bead to the outside of the wheel.

Use the tire changer in order to install the tire to the wheel. Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, lubricate the beads and reinflate. Overinflating may cause the bead to break and cause serious personal injury. Important: Allowable bead seating pressure is 345 kPa (50 psi) on Extended Mobility Tires. 14. Inflate the tire until it passes the bead humps. Be sure that the valve core is not installed at this time. 15. Install the valve core to the valve core stem. 16. Inflate the tire to the proper air pressure. 17. Ensure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.

Please discard Corporate Bulletin Number 06-02-32-013A (Section 02 - Steering). A recently completed analysis of returned power steering (PS) pumps that had been replaced for noise, no power assist, no or low pressure and leaking conditions has indicated a high number of "No Trouble Found" results. Corporate Bulletin Number 01-02-32-004 indicates that when attempting to repair a power steering concern, the steering system analyzer should be utilized to assist the technician in a successful diagnosis. Note- Saturn ASTRA does not utilize the Power Steering System Analyzer. In addition, extensive warranty analysis has shown that the following situations are all significant root causes of PS pump failures: - Improper pulley installation - Re-using the O-rings - Using fluid other than the OE-specified steering fluid - Failure to flush the PS system In order to help improve customer satisfaction and reduce comebacks, GM recommends the following tips for replacing a PS pump: 1. Low or no pressure from the PS pump may be the results of dirty or contaminated fluid, which could cause the pressure relief valve to stop functioning. Using the proper tools, flush and bleed the PS system. Any residual contaminants will result in pump failure. 2. When removing the pulley, use the proper special tools. Because the pulley alignment is critical, distorting the pulley may damage bearings on the new PS pump. Note Some new PS pumps may not include a new O-ring. Please refer to the appropriate Parts Catalog. Saturn retailers should refer to the appropriate model year Parts & Illustration Catalog for the vehicle. 3. Be sure to use only the new O-rings included with the PS pump. The new reservoir O-ring must be lubricated with OE-specific PS fluid prior to installation. Also make sure that the control valve O-ring is in its exact groove position and is NOT covering the pressure bypass hole. 4. Bleed the PS system according to the procedures/recommendations in SI. Following these procedures and using the correct tools and fluids should help ensure that the new PS pump operates properly. Skipping steps may cost you time and trouble later.

Please discard Corporate Bulletin Number 09-09-40-001 (Section 09 - Restraints). This bulletin is being published to advise dealers about seat belt buckles not operating and/or seat belt warning light illumination, as well as difficulty latching and unlatching the buckle or the buckle release button sticking. Analysis of warranty data has determined that this condition may be caused by sticky beverages being spilled onto or into the seat belt buckle assembly. Foreign debris from food, candy wrappers, paper and coins can also contribute to this condition. Important If foreign material (debris) or sticky liquids are the cause of the concern, show the customer the condition of the component (buckle assembly) and explain how it is affecting the function of the restraint system. Strongly recommend that the component be replaced. Point out the fact that this is not a manufacturing defect and is not covered by the new vehicle warranty. If the customer declines to have parts replaced, the service department management must make a notation on the service record that the lack of functionality of seating position with an inoperative buckle was fully explained to the customer. The service department management must advise the customer that having a non-functioning buckle in a seating position voids ability to use that seating position (no one should ride in the seat). Also make the customer aware that it may be against the law to ride in a vehicle without wearing a restraint system. Important Never insert anything other than the seat belt latch plate into the buckle assembly. Do not attempt to dig anything out of a buckle with a tool. Never try to wash out a buckle to remove a spilled liquid as this may damage the buckle. Use the following steps to determine the cause of the concern. 1. Inspect the buckle assembly with a light shining on the latch plate insertion area. Look for any debris or foreign objects in the buckle. 2. If any debris or foreign objects are observed, try to vacuum out the item. After the foreign material is removed, latch and unlatch the seat belt. If the system functions properly, do not replace the seat belt buckle assembly. 3. If the condition has not been corrected, inspect the buckle assembly for any sticky residue. If sticky residue is found, inform the customer that a substance was spilled on the seat belt buckle assembly causing the malfunction. The buckle assembly will need to be replaced at the customer's expense. 4. Refer to SI for seat belt component replacement. Important If foreign material (debris) or sticky liquids are the cause of the concern, show the customer the condition of the component (buckle assembly) and explain how it is affecting the function of the restraint system.

Please discard Corporate Bulletin Number 09-09-40-001 (Section 09 - Restraints). This bulletin is being published to advise dealers about seat belt buckles not operating and/or seat belt warning light illumination, as well as difficulty latching and unlatching the buckle or the buckle release button sticking. Analysis of warranty data has determined that this condition may be caused by sticky beverages being spilled onto or into the seat belt buckle assembly. Foreign debris from food, candy wrappers, paper and coins can also contribute to this condition. Important If foreign material (debris) or sticky liquids are the cause of the concern, show the customer the condition of the component (buckle assembly) and explain how it is affecting the function of the restraint system. Strongly recommend that the component be replaced. Point out the fact that this is not a manufacturing defect and is not covered by the new vehicle warranty. If the customer declines to have parts replaced, the service department management must make a notation on the service record that the lack of functionality of seating position with an inoperative buckle was fully explained to the customer. The service department management must advise the customer that having a non-functioning buckle in a seating position voids ability to use that seating position (no one should ride in the seat). Also make the customer aware that it may be against the law to ride in a vehicle without wearing a restraint system. Important Never insert anything other than the seat belt latch plate into the buckle assembly. Do not attempt to dig anything out of a buckle with a tool. Never try to wash out a buckle to remove a spilled liquid as this may damage the buckle. Use the following steps to determine the cause of the concern. 1. Inspect the buckle assembly with a light shining on the latch plate insertion area. Look for any debris or foreign objects in the buckle. 2. If any debris or foreign objects are observed, try to vacuum out the item. After the foreign material is removed, latch and unlatch the seat belt. If the system functions properly, do not replace the seat belt buckle assembly. 3. If the condition has not been corrected, inspect the buckle assembly for any sticky residue. If sticky residue is found, inform the customer that a substance was spilled on the seat belt buckle assembly causing the malfunction. The buckle assembly will need to be replaced at the customer's expense. 4. Refer to SI for seat belt component replacement. Important If foreign material (debris) or sticky liquids are the cause of the concern, show the customer the condition of the component (buckle assembly) and explain how it is affecting the function of the restraint system.

Please discard Corporate Bulletin Number 05-06-02-001 (Section 06 - Engine/Propulsion System). Important: 2004-05 Chevrolet Aveo (Pontiac Wave, Canada Only) does not use DEX-COOL(R). Refer to the flushing procedure explained later in this bulletin. The following information should be utilized when servicing aluminum heater core and/or radiators on repeat visits. A replacement may be necessary because erosion, corrosion, or insufficient inhibitor levels may cause damage to the heater core, radiator or water pump. A coolant check should be performed whenever a heater core, radiator, or water pump is replaced. The following procedures/ inspections should be done to verify proper coolant effectiveness. Caution: To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if the radiator cap or surge tank cap is removed while the engine and radiator are still hot. Important: If the vehicle's coolant is low, drained out, or the customer has repeatedly added coolant or water to the system, then the system should be completely flushed using the procedure explained later in this bulletin. Technician Diagnosis ^ Verify coolant concentration. A 50% coolant/water solution ensures proper freeze and corrosion protection. Inhibitor levels cannot be easily measured in the field, but can be indirectly done by the measurement of coolant concentration. This must be done by using a Refractometer J 23688 (Fahrenheit scale) or J 26568 (centigrade scale), or equivalent, coolant tester. The Refractometer uses a minimal amount of coolant that can be taken from the coolant recovery reservoir, radiator or the engine block. Inexpensive gravity float testers (floating balls) will not completely analyze the coolant concentration fully and should not be used. The concentration levels should be between 50% and 65% coolant concentrate. This mixture will have a freeze point protection of -34 degrees Fahrenheit (-37 degrees Celsius). If the concentration is below 50%, the cooling system must be flushed. ^ Inspect the coolant flow restrictor if the vehicle is equipped with one. Refer to Service Information (SI) and/or the appropriate Service Manual for component location and condition for operation. ^ Verify that no electrolysis is present in the cooling system. This electrolysis test can be performed before or after the system has been repaired. Use a digital voltmeter set to 12 volts. Attach one test lead to the negative battery post and insert the other test lead into the radiator coolant, making sure the lead does not touch the filler neck or core. Any voltage reading over 0.3 volts indicates that stray current is finding its way into the coolant. Electrolysis is often an intermittent condition that occurs when a device or accessory that is mounted to the radiator is energized. This type of current could be caused from a poorly grounded cooling fan or some other accessory and can be verified by watching the volt meter and turning on and off various accessories or engage the starter motor. Before using one of the following flush procedures, the coolant recovery reservoir must be removed, drained, cleaned and reinstalled before refilling the system. Notice: ^ Using coolant other than DEX‐COOL(R) may cause premature engine, heater core or radiator corrosion. In addition, the engine coolant may require changing sooner, at 30,000 miles (50,000 km) or 24 months, whichever occurs first. Any repairs would not be covered by your warranty. Always use DEX‐COOL(R) (silicate free) coolant in your vehicle. ^ If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost would not be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Steering > Power Steering > Steering Control Module > Component Information > Component Information > Technical Service Bulletins > Cooling System, A/C - Aluminum Heater Cores/Radiators > Page 13095 Flushing Procedures using DEX-COOL(R) Important: The following procedure recommends refilling the system with DEX-COOL(R), P/N 12346290 (in Canada, use P/N 10953464), GM specification 6277M. This coolant is orange in color and has a service interval of 5 years or 240,000 km (150,000 mi). However, when used on vehicles built prior to the introduction of DEX-COOL(R), maintenance intervals will remain the same as specified in the Owner's Manual. ^ If available, use the approved cooling system flush and fill machine (available through the GM Dealer Equipment Program) following the manufacturer's operating instructions. ^ If approved cooling system flush and fill machine is not available, drain the coolant and dispose of properly following the draining procedures in the appropriate Service Manual. Refill the system using clear, drinkable water and run the vehicle until the thermostat opens. Repeat and run the vehicle three (3) times to totally remove the old coolant or until the drained coolant is almost clear. Once the system is completely flushed, refill the cooling system to a 50%-60% concentration with DEX‐COOL(R), P/N 12346290 (in Canada, use P/N 10953464), GM specification 6277M, following the refill procedures in the appropriate Service Manual. If a Service Manual is not available, fill half the capacity of the system with 100% DEX-COOL(R), P/N 12346290 (in Canada, use P/N 10953464), GM specification 6277M. Then slowly add clear, drinkable water (preferably distilled) to the system until the level of the coolant mixture has reached the base of the radiator neck. Wait two (2) minutes and reverify the coolant level. If necessary, add clean water to restore the coolant to the appropriate level. Once the system is refilled, reverify the coolant concentration using a Refractometer J 23688 (Fahrenheit scale) or J 26568 (centigrade scale) coolant tester, or equivalent. The concentration levels should be between 50% and 65%. Flushing Procedures using Conventional Silicated (Green Colored) Coolant Important: 2004-2005 Chevrolet Aveo (Pontiac Wave, Canada Only) does not use DEX‐COOL(R). The Aveo and Wave are filled with conventional, silicated engine coolant that is blue in color. Silicated coolants are typically green in color and are required to be drained, flushed and refilled every 30,000 miles (48,000 km). The Aveo and Wave are to be serviced with conventional, silicated coolant. Use P/N 12378560 (1 gal) (in Canada, use P/N 88862159 (1 L). Refer to the Owner's Manual or Service Information (SI) for further information on OEM coolant. Important: Do not mix the OEM orange colored DEX-COOL(R) coolant with green colored coolant when adding coolant to the system or when servicing the vehicle's cooling system. Mixing the orange and green colored coolants will produce a brown coolant which may be a customer dissatisfier and will not extend the service interval to that of DEX-COOL(R). Conventional silicated coolants offered by GM Service and Parts Operations are green in color. ^ If available, use the approved cooling system flush and fill machine (available through the GM Dealer Equipment Program) following the manufacturer's operating instructions. ^ If approved cooling systems flush and fill machine is not available, drain coolant and dispose of properly following the draining procedures in appropriate Service Manual. Refill the system using clear, drinkable water and run vehicle until thermostat opens. Repeat and run vehicle three (3) times to totally remove old coolant or until drained coolant is almost clear. Once the system is completely flushed, refill the cooling system to a 50%-60% concentration with a good quality ethylene glycol base engine coolant, P/N 12378560, 1 gal (in Canada, use P/N 88862159 1 L), conforming to GM specification 1825M, or recycled coolant conforming to GM specification 1825M, following the refill procedures in the appropriate Service Manual. If a Service Manual is not available, fill half the capacity of the system with 100% good quality ethylene glycol base (green colored) engine coolant, P/N 12378560 1 gal., (in Canada, use P/N 88862159 1 L) conforming to GM specification 1825M. Then slowly add clear, drinkable water (preferably distilled) to system until the level of the coolant mixture has reached the base of the radiator neck. Wait two (2) minutes and recheck coolant level. If necessary, add clean water to restore coolant to the appropriate level. Once the system is refilled, recheck the coolant concentration using a Refractometer J 23688 (Fahrenheit scale) or J 26568 (centigrade scale) coolant tester, or equivalent. Concentration levels should be between 50% and 65%.

There are parts of the SIR system installed in various locations around a vehicle. To find the location of the SIR components refer to SIR Identification Views. There are several reasons for disabling the SIR system, such as repairs to the SIR system or servicing a component near or attached to an SIR component. There are several ways to disable the SIR system depending on what type of service is being performed. The following information covers the proper procedures for disabling/enabling the SIR system. SIR Service Precautions Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Failure to observe the correct procedure could cause deployment of the SIR components. Serious injury can occur. Failure to observe the correct procedure could also result in unnecessary SIR system repairs. The inflatable restraint sensing and diagnostic module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the air bags if the SDM loses battery power during a collision. Deployment power is available for as much as 1 minute after disconnecting the vehicle power. Waiting 1 minute before working on the system after disabling the SIR system prevents deployment of the air bags from the reserved energy supply. General Service Instructions The following are general service instructions which must be followed in order to properly repair the vehicle and return it to its original integrity: * Do not expose inflator modules to temperatures above 65°C (150°F). * Verify the correct replacement part number. Do not substitute a component from a different vehicle. * Use only original GM replacement parts available from your authorized GM dealer. Do not use salvaged parts for repairs to the SIR system. Discard any of the following components if it has been dropped from a height of 91 cm (3 feet) or greater: * Inflatable restraint sensing and diagnostic module (SDM) * Any Inflatable restraint air bag module * Inflatable restraint steering wheel module coil * Any Inflatable restraint sensor * Inflatable restraint seat belt pretensioners * Inflatable restraint Passenger Presence System (PPS) module or sensor Disabling Procedure - Air Bag Fuse 1. Turn the steering wheel so that the vehicles wheels are pointing straight ahead. 2. Place the ignition in the OFF position. Important: The SDM may have more than one fused power input. To ensure there is no unwanted SIR deployment, personal injury, or unnecessary SIR system repairs, remove all fuses supplying power to the SDM. With all SDM fuses removed and the ignition switch in the ON position, the AIR BAG warning indicator illuminates. This is normal operation, and does not indicate a SIR system malfunction. 3. Locate and remove the fuse(s) supplying power to the SDM. 4. Wait 1 minute before working on the system. Enabling Procedure - Air Bag Fuse 1. Place the ignition in the OFF position.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Steering > Steering Wheel > Component Information > Description and Operation Steering Wheel: Description and Operation Steering Wheel and Column Description and Operation The steering wheel and column has 4 primary functions: * Vehicle steering * Vehicle security * Driver convenience * Driver safety Vehicle Steering The steering wheel is the first link between the driver and the vehicle. The steering wheel is fastened to a steering shaft within the column. At the lower end of the column, the intermediate shaft connects the column to the steering gear. Vehicle Security-Some Vehicle Models Theft deterrent components are mounted and designed into the steering column. The following components allow the column to be locked in order to minimize theft: * The ignition switch * The steering column lock * The ignition cylinder Driver Convenience The steering wheel and column may also have driver controls attached for convenience and comfort. The following controls may be mounted on or near the steering wheel or column. * The turn signal switch * The hazard switch * The headlamp dimmer switch * The wiper/washer switch * The horn pad/cruise control switch * The tilt or tilt/telescoping functions Driver Safety The energy-absorbing steering column compresses in the event of a front-end collision, which reduces the chance of injury to the driver. The mounting capsules break away from the mounting bracket in the event of an accident. Ignition Lock Cylinder Control Actuator If the vehicle is equipped with a floor mounted console gear shifter, it has a ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator's purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in gear and the vehicle may still be moving. The column ignition lock system consists of a ignition lock cylinder control actuator, and a Park position switch that is located in the automatic transmission (A/T) shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded out to mechanically prevent the ignition key cylinder from being turned to the Lock position when vehicle transmission is not in the Park position. If vehicle power is lost, and/or the transmission is not in the Park position the operator will not be able to turn the ignition key to the Lock position and will not be able to remove the ignition key from the column.

Please discard Corporate Bulletin Number 05-03-08-002B (Section 03 - Suspension). This bulletin is intended to help identify the severity of shock absorber and strut fluid seepage. Improper diagnosis may lead to components being replaced that are within the manufacturer's specification. Shock absorbers and strut assemblies are fluid-filled components and will normally exhibit some seepage. Seepage is defined as oil film or dust accumulation on the exterior of the shock housing. Shock absorbers and struts are not to be replaced under warranty for seepage. Use the following information to determine if the condition is normal acceptable seepage or a defective component. Important Electronically controlled shock absorbers (MR) may have a tendency to attract dust to this oil film. Often this film and dust can be wiped off and will not return until similar mileage is accumulated again. Inspection Procedure Note The shock absorber or strut assembly DOES NOT have to be removed from the vehicle to perform the following inspection procedure. Use the following descriptions and graphics to determine the serviceability of the component. Shock Absorbers Do Not Replace shock absorbers displaying condition 1 or 2 levels of seepage. 1. Oil or fluid residue only on the bottom or top of the shock absorber and not originating from the shaft seal (the upper part of the lower shock tube). 2. Light film/residue on approximately 1/3 (a) or less of the lower shock tube (A) and originating from the shaft seal. Replace shock absorbers displaying conditions 3 and 4 levels of leaks. 3. Oil drip or trail down the lower shock tube and originating from the shaft seal. 4. An extreme wet film of oil covering more than 1/3 (b) of the lower shock tube and originating from the shaft seal.

When dismounting and mounting tires, care must be taken when breaking the bead loose from the wheel. If the tire machines bead breaking fixture is positioned too close to the tire pressure sensor, as the tire bead breaks away from the wheel it may be forced into, or catch on the edge of the tire pressure sensor. This can damage the sensor and require the sensor to be replaced. Care must also be taken when transferring the tire bead to the other side of the wheel rim. As the tire machine rotates and the tire bead is stretched around the wheel rim, the bead can come in contact with the sensor if it is not correctly positioned in relation to the mounting/dismounting head prior to tire mounting/dismounting. This can also cause sensor damage requiring replacement. Procedure Notice: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result. Notice: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel. 1. Remove the valve core from the valve stem. 2. Deflate the tire completely. Important: Rim-clamp European-type tire changers are recommended. 3. Use the tire changer in order to remove the tire from the wheel. Follow steps 4-7 to remove the tire from the wheel. 4. When separating the tire bead from the wheel position the bead breaking fixture 90, 180 and 270 degrees from the valve stem.

Position the wheel and tire so the valve stem is situated at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the outer tire bead up and over the mounting/dismounting head. 6. Position the wheel and tire so that the valve stem is situated again at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the inner tire bead up and over the mounting/dismounting head. 7. Remove all residual liquid sealant from the inside of the tire and wheel surfaces. If any tire sealant is noted upon tire dismounting on vehicles equipped with TPM replace the tire pressure sensor. 8. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats. Important: If bead seat corrosion has been identified as an air loss concern on the wheel being worked on, refer to GM Service Bulletin # 08-03-10-006 for additional information on correcting the leak. 9. Apply GM P/N 12345884 (in Canada, P/N 5728223) or equivalent to the tire bead and the wheel rim.

Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim. 11. Position the rim so that the valve stem (1) is situated at the 3 o'clock position relative to the head (2). This will protect the sensor when the bottom bead seats. 12. After the bottom bead is on the wheel, reposition the wheel and tire so that the valve stem is situated at the 9 o'clock position relative to the head. This will protect the sensor while mounting the tire bead to the outside of the wheel.

Use the tire changer in order to install the tire to the wheel. Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, lubricate the beads and reinflate. Overinflating may cause the bead to break and cause serious personal injury. Important: Allowable bead seating pressure is 345 kPa (50 psi) on Extended Mobility Tires. 14. Inflate the tire until it passes the bead humps. Be sure that the valve core is not installed at this time. 15. Install the valve core to the valve core stem. 16. Inflate the tire to the proper air pressure. 17. Ensure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.

Maintaining proper tire pressures is an Owner's Maintenance item and is not covered under warranty. This bulletin is being revised to add model years and update additional bulletin reference information. Please discard Corporate Bulletin Number 09-03-16-002 (Section 03 -- Suspension). Customer Concerns and Confusion with the Tire Pressure Monitoring (TPM) System The following procedure should be used by dealership service consultants when a customer comes into the service drive with a "low tire light" on or comments on a check tire pressure/low tire pressure/add air to tire or service tire monitor system message. The service consultant should perform the following steps: Procedure Turn the key to ON, without starting the engine. ^ If the low tire light comes on and stays on solid with a check tire pressure/low tire pressure/add air to tire message (on vehicles equipped with DIC), advise the customer: - The system is working properly. - Properly adjusting all tire air pressures to the recommended levels and driving the vehicle will turn the light off (refer to the Tire and Loading Information label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". ^ If the Tire Pressure Monitor (TPM) light blinks for one minute then stays on solid with a service tire monitor system message (on vehicles equipped with DIC): - A TPM system problem exists. The vehicle should be written up accordingly and sent to your service department for further DTC diagnosis and service. - If dashes (--) are displayed in only one or two of the tire pressure readouts, it is likely caused by a previous TPM system relearn that was performed incorrectly due to interference from another vehicle's TPM system during the relearn process (refer to the Important statement later in this bulletin regarding TPM relearn with a Tech 2(R)). - If dashes (--) are displayed in all four of the tire pressure readouts, there is a system problem. Follow the appropriate SI service procedures. ^ If a customer indicates the low tire light comes on for a few minutes when the vehicle is started, then goes off after driving a while, advise the customer: - The system is working properly. - Most likely, air pressure in one or more of the tires is low enough to turn the light on when tires are cold. After driving for a while, tires will heat Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tire Monitoring System > Low Tire Pressure Indicator > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 13393 up, allowing tire air pressure to increase above the threshold causing the light to go off. Properly adjusting all tire air pressures to the recommended levels will correct this (Refer to the Tire and Loading Information Label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". For more detailed information, refer to Corporate Bulletin Number 07-03-16-004C and TPMS Training Course 13044.12T2. Tire Pressure Light At key on, without starting the vehicle: Steady Solid Glowing TPM Indicator If the TPM indicator appears as a steady glowing yellow lamp (as above), the system is functioning properly and you should add air to the tires to correct this condition. Blinking TPM Indicator If the TPM indicator appears as a BLINKING yellow lamp for one minute and then stays on solid, diagnostic service is needed. The Effect of Outside Temperature on Tire Pressures Important: As a rule of thumb, tire pressure will change about 7kPa (1 psi) for every 6°C (10°F) decrease in temperature - Tire pressure will drop when it gets colder outside, and rise when it gets warmer. Under certain situations such as extreme outside temperature changes, the system may bring on a solid light with a check tire pressure message. This should be considered normal and the system is working properly. The light will turn off upon adding the proper amount of air to the tires (refer to the Tire & Loading Information label in the driver's door opening). When properly adjusting tire air pressure, the following steps are important to help optimize the system and prolong bringing a tire pressure light on: ^ Use an accurate, high quality tire pressure gauge. ^ Never set the tire pressure below the specified placard value regardless of tire temperature or ambient temperature. ^ Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will encounter during operation. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tire Monitoring System > Low Tire Pressure Indicator > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 13394 ^ When adding proper tire air pressure, it is important to remember fluctuations in outside air temperatures and tire temperatures effect tire air pressures. ^ After you have added the proper tire pressure, if the vehicle has a DIC (after the system has updated), check to see if DIC displays are the same readings as the tire pressure gauge used (adjust as necessary). ^ Only perform a TPM sensor re-learn after a tire rotation or system part replacements and use the Tech 2(R) to initiate the relearn whenever possible to avoid invalid sensor I.D. learns. Important: Always take outside temperature and tire temperature into consideration to properly set tire pressures. Foe example, on colder days (20°F/-7°C), if setting tire pressure when the vehicle has been indoors (60°F/16°C) or the tires are warm from being driven, it will be necessary to compensate for the low outside temperature by adding 21-27 kPa (3-4 psi) more then the placecard pressure. At some later time, when the vehicle has been parked outside for a while, the tires will cool off and the pressures will drop back into the placecard range. Important: Recently, nitrogen gas (for use in inflating tires) has become available to the general customer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. Tires inflated with nitrogen gas may exhibit less of a pressure change in response to outside temperature changes. Nitrogen gas inflation is compatible with GM TPM sensors. For additional information, refer to Corporate Service Bulletin 05-03-10-020C. Important: All Models (Except the Pontiac Vibe): Do not perform a TPM relearn at PDI, the system has already been set at the Assembly Plant. Do not perform a TPM relearn after adding air to the tires. The low tire light is similar to the low fuel indicator and adding something (fuel, air) to the vehicle makes that light turn back off again. Note that because of system behavior, some vehicles must be driven a short distance before the sensors recognize the increase in pressure and turns the light off again. Pontiac Vibe Only: Do not use the TPMS reset button to turn off the light. The system will update and light will turn off when all tire pressures have been adjusted followed by short distance drive. Important: All models (except the Pontiac Vibe): Each tire monitor sensor is learned to a specific vehicle corner. When performing a TPM relearn (only after a tire rotation or replacement of a TPM sensor or Module), always use the Tech2(R) to initiate the J 46079 relearned process. Tech 2(R) - initiated relearns lock out other vehicle TPM signals that may be broadcasting in the area. Only signals initiated by the J 46079 tool will be accepted. This method avoids storing false TPM I.D.s and will prevent customers from returning with dashes (--) displayed in tire pressure readouts and/or a flashing tire pressure monitor (TPM) light. Checking the four TPM I.D.s with the Tech 2(R) prior to and following relearn to verify they are the same can prevent invalid I.D. learns. Pontiac Vibe Only: Tire Monitor Sensors are not learned to a specific vehicle corner. Do not perform a TPM Reset after tire rotation. The TPMS Reset button must only be used during pre-delivery inspection by the dealer to initialize the system (after all tire pressures have been adjusted properly) or when a Tire Pressure Monitor System component is replaced. The J 46079 tool does not work on Vibe TPM sensors. A TPMS relearn on Vibe must be preformed with a Tech 2(R) to set the TPMS Module in learn mode. The TPMS sensor IDs are entered through the Tech 2(R). Refer to SI for further Vibe TPMS information. Labor Operation and Repair Order/Warranty System Claim Required Documentation Important: The ONLY time labor operation E0726 or E0722 should be used is to diagnose for a system issue. That should ONLY occur if, at key ON, without starting the engine, the Tire Pressure Monitor (TPM) blinks for one minute and then stays on solid with a Service Tire Monitor System message (on vehicles equipped with a DIC) If that occurs, a TPM system problem exists and the system will have set a DTC. If one of these operastions is used, the following Repair Order and Warranty System documentation are required: ^ Document the customer complaint on the Repair Order. ^ Document the TPMS DTC that has set on the Repair Order. ^ Enter the TPMS DTC in the Warranty System (WINS) in the Failure Code/DTC field on the claim submission (refer to the Claims Processing Manual, Section IV, Warranty claim Data, Page 6, Item G). If the above information is not documented on the Repair Order and Warranty System, the claim may be rejected. If the Warranty Parts Center (WPC) generates a request, this repair order documentation must be sent back.

Return rates ran as high as 60% with the TPM sensors still attached. Operational TPM sensors should not be returned to GM and are to be transferred to replacement wheels if they become necessary. Important: Operational TPM Sensors that are returned under warranty to General Motors will be charged back to the dealer.Sensors have a 10 year /150,000 mile (240,000 km) battery life, and should be transferred if one or more wheels are replaced. TPM Valve Stem / Grommet (0-ring) Replacement When the TPM sensors are transferred to new wheels you should replace the component used to seal the TPM sensor stem to the wheel. On sensors with an aluminum stem and visible nut on the outside of the wheel a replacement grommet (0-ring) should be used to assure a proper seal. The sensor retaining nut (except Aveo) should be tightened to 7 N.m (62 lb in) for all vehicles except Pontiac Vibe (4.0 N.m (35.4 lb in)). Important: ^ DO NOT overtorque the retaining nut. Notice: ^ Factory installed TPM Sensors come with plastic aluminum or nickel-plated brass stem caps. These caps should not be changed. Chrome plated steel caps may cause corrosion of aluminum valve stems due to incompatibility of the metals. On current style sensors the entire rubber stem is replaceable. The service interval on the revised TPM sensor with replaceable stem is the same as for any other traditional valve stem. Replace the stem at the time of tire replacement sensor transfer or whenever air seepage is suspected at the valve stem. When replacing the valve stem tighten the screw to 1.3 N.m (11.5 lb in). For either style of TPM sensor see the service parts guide for the correct GM part numbers to order and use.

When dismounting and mounting tires, care must be taken when breaking the bead loose from the wheel. If the tire machines bead breaking fixture is positioned too close to the tire pressure sensor, as the tire bead breaks away from the wheel it may be forced into, or catch on the edge of the tire pressure sensor. This can damage the sensor and require the sensor to be replaced. Care must also be taken when transferring the tire bead to the other side of the wheel rim. As the tire machine rotates and the tire bead is stretched around the wheel rim, the bead can come in contact with the sensor if it is not correctly positioned in relation to the mounting/dismounting head prior to tire mounting/dismounting. This can also cause sensor damage requiring replacement. Procedure Notice: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result. Notice: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel. 1. Remove the valve core from the valve stem. 2. Deflate the tire completely. Important: Rim-clamp European-type tire changers are recommended. 3. Use the tire changer in order to remove the tire from the wheel. Follow steps 4-7 to remove the tire from the wheel. 4. When separating the tire bead from the wheel position the bead breaking fixture 90, 180 and 270 degrees from the valve stem.

Position the wheel and tire so the valve stem is situated at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the outer tire bead up and over the mounting/dismounting head. 6. Position the wheel and tire so that the valve stem is situated again at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the inner tire bead up and over the mounting/dismounting head. 7. Remove all residual liquid sealant from the inside of the tire and wheel surfaces. If any tire sealant is noted upon tire dismounting on vehicles equipped with TPM replace the tire pressure sensor. 8. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats. Important: If bead seat corrosion has been identified as an air loss concern on the wheel being worked on, refer to GM Service Bulletin # 08-03-10-006 for additional information on correcting the leak. 9. Apply GM P/N 12345884 (in Canada, P/N 5728223) or equivalent to the tire bead and the wheel rim.

Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim. 11. Position the rim so that the valve stem (1) is situated at the 3 o'clock position relative to the head (2). This will protect the sensor when the bottom bead seats. 12. After the bottom bead is on the wheel, reposition the wheel and tire so that the valve stem is situated at the 9 o'clock position relative to the head. This will protect the sensor while mounting the tire bead to the outside of the wheel.

Use the tire changer in order to install the tire to the wheel. Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, lubricate the beads and reinflate. Overinflating may cause the bead to break and cause serious personal injury. Important: Allowable bead seating pressure is 345 kPa (50 psi) on Extended Mobility Tires. 14. Inflate the tire until it passes the bead humps. Be sure that the valve core is not installed at this time. 15. Install the valve core to the valve core stem. 16. Inflate the tire to the proper air pressure. 17. Ensure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.

Maintaining proper tire pressures is an Owner's Maintenance item and is not covered under warranty. This bulletin is being revised to add model years and update additional bulletin reference information. Please discard Corporate Bulletin Number 09-03-16-002 (Section 03 -- Suspension). Customer Concerns and Confusion with the Tire Pressure Monitoring (TPM) System The following procedure should be used by dealership service consultants when a customer comes into the service drive with a "low tire light" on or comments on a check tire pressure/low tire pressure/add air to tire or service tire monitor system message. The service consultant should perform the following steps: Procedure Turn the key to ON, without starting the engine. ^ If the low tire light comes on and stays on solid with a check tire pressure/low tire pressure/add air to tire message (on vehicles equipped with DIC), advise the customer: - The system is working properly. - Properly adjusting all tire air pressures to the recommended levels and driving the vehicle will turn the light off (refer to the Tire and Loading Information label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". ^ If the Tire Pressure Monitor (TPM) light blinks for one minute then stays on solid with a service tire monitor system message (on vehicles equipped with DIC): - A TPM system problem exists. The vehicle should be written up accordingly and sent to your service department for further DTC diagnosis and service. - If dashes (--) are displayed in only one or two of the tire pressure readouts, it is likely caused by a previous TPM system relearn that was performed incorrectly due to interference from another vehicle's TPM system during the relearn process (refer to the Important statement later in this bulletin regarding TPM relearn with a Tech 2(R)). - If dashes (--) are displayed in all four of the tire pressure readouts, there is a system problem. Follow the appropriate SI service procedures. ^ If a customer indicates the low tire light comes on for a few minutes when the vehicle is started, then goes off after driving a while, advise the customer: - The system is working properly. - Most likely, air pressure in one or more of the tires is low enough to turn the light on when tires are cold. After driving for a while, tires will heat Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 13419 up, allowing tire air pressure to increase above the threshold causing the light to go off. Properly adjusting all tire air pressures to the recommended levels will correct this (Refer to the Tire and Loading Information Label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". For more detailed information, refer to Corporate Bulletin Number 07-03-16-004C and TPMS Training Course 13044.12T2. Tire Pressure Light At key on, without starting the vehicle: Steady Solid Glowing TPM Indicator If the TPM indicator appears as a steady glowing yellow lamp (as above), the system is functioning properly and you should add air to the tires to correct this condition. Blinking TPM Indicator If the TPM indicator appears as a BLINKING yellow lamp for one minute and then stays on solid, diagnostic service is needed. The Effect of Outside Temperature on Tire Pressures Important: As a rule of thumb, tire pressure will change about 7kPa (1 psi) for every 6°C (10°F) decrease in temperature - Tire pressure will drop when it gets colder outside, and rise when it gets warmer. Under certain situations such as extreme outside temperature changes, the system may bring on a solid light with a check tire pressure message. This should be considered normal and the system is working properly. The light will turn off upon adding the proper amount of air to the tires (refer to the Tire & Loading Information label in the driver's door opening). When properly adjusting tire air pressure, the following steps are important to help optimize the system and prolong bringing a tire pressure light on: ^ Use an accurate, high quality tire pressure gauge. ^ Never set the tire pressure below the specified placard value regardless of tire temperature or ambient temperature. ^ Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will encounter during operation. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 13420 ^ When adding proper tire air pressure, it is important to remember fluctuations in outside air temperatures and tire temperatures effect tire air pressures. ^ After you have added the proper tire pressure, if the vehicle has a DIC (after the system has updated), check to see if DIC displays are the same readings as the tire pressure gauge used (adjust as necessary). ^ Only perform a TPM sensor re-learn after a tire rotation or system part replacements and use the Tech 2(R) to initiate the relearn whenever possible to avoid invalid sensor I.D. learns. Important: Always take outside temperature and tire temperature into consideration to properly set tire pressures. Foe example, on colder days (20°F/-7°C), if setting tire pressure when the vehicle has been indoors (60°F/16°C) or the tires are warm from being driven, it will be necessary to compensate for the low outside temperature by adding 21-27 kPa (3-4 psi) more then the placecard pressure. At some later time, when the vehicle has been parked outside for a while, the tires will cool off and the pressures will drop back into the placecard range. Important: Recently, nitrogen gas (for use in inflating tires) has become available to the general customer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. Tires inflated with nitrogen gas may exhibit less of a pressure change in response to outside temperature changes. Nitrogen gas inflation is compatible with GM TPM sensors. For additional information, refer to Corporate Service Bulletin 05-03-10-020C. Important: All Models (Except the Pontiac Vibe): Do not perform a TPM relearn at PDI, the system has already been set at the Assembly Plant. Do not perform a TPM relearn after adding air to the tires. The low tire light is similar to the low fuel indicator and adding something (fuel, air) to the vehicle makes that light turn back off again. Note that because of system behavior, some vehicles must be driven a short distance before the sensors recognize the increase in pressure and turns the light off again. Pontiac Vibe Only: Do not use the TPMS reset button to turn off the light. The system will update and light will turn off when all tire pressures have been adjusted followed by short distance drive. Important: All models (except the Pontiac Vibe): Each tire monitor sensor is learned to a specific vehicle corner. When performing a TPM relearn (only after a tire rotation or replacement of a TPM sensor or Module), always use the Tech2(R) to initiate the J 46079 relearned process. Tech 2(R) - initiated relearns lock out other vehicle TPM signals that may be broadcasting in the area. Only signals initiated by the J 46079 tool will be accepted. This method avoids storing false TPM I.D.s and will prevent customers from returning with dashes (--) displayed in tire pressure readouts and/or a flashing tire pressure monitor (TPM) light. Checking the four TPM I.D.s with the Tech 2(R) prior to and following relearn to verify they are the same can prevent invalid I.D. learns. Pontiac Vibe Only: Tire Monitor Sensors are not learned to a specific vehicle corner. Do not perform a TPM Reset after tire rotation. The TPMS Reset button must only be used during pre-delivery inspection by the dealer to initialize the system (after all tire pressures have been adjusted properly) or when a Tire Pressure Monitor System component is replaced. The J 46079 tool does not work on Vibe TPM sensors. A TPMS relearn on Vibe must be preformed with a Tech 2(R) to set the TPMS Module in learn mode. The TPMS sensor IDs are entered through the Tech 2(R). Refer to SI for further Vibe TPMS information. Labor Operation and Repair Order/Warranty System Claim Required Documentation Important: The ONLY time labor operation E0726 or E0722 should be used is to diagnose for a system issue. That should ONLY occur if, at key ON, without starting the engine, the Tire Pressure Monitor (TPM) blinks for one minute and then stays on solid with a Service Tire Monitor System message (on vehicles equipped with a DIC) If that occurs, a TPM system problem exists and the system will have set a DTC. If one of these operastions is used, the following Repair Order and Warranty System documentation are required: ^ Document the customer complaint on the Repair Order. ^ Document the TPMS DTC that has set on the Repair Order. ^ Enter the TPMS DTC in the Warranty System (WINS) in the Failure Code/DTC field on the claim submission (refer to the Claims Processing Manual, Section IV, Warranty claim Data, Page 6, Item G). If the above information is not documented on the Repair Order and Warranty System, the claim may be rejected. If the Warranty Parts Center (WPC) generates a request, this repair order documentation must be sent back.

The driver information center (DIC), if equipped, will also display a SERVICE TIRE MONITOR type message. When the road tire is repaired and reinstalled in the original location, the TPM indicator icon illumination and DIC message may remain displayed until the DTC is cleared. To ensure that the TPM indicator and the DIC message are cleared after service, it is necessary to clear any TPM DTCs using a scan tool.

This bulletin covers puncture repair procedures for passenger car and light duty truck radial tires in the tread area only. The tire manufacturer must be contacted for its individual repair policy and whether or not the speed rating is retained after repair. Caution - Tire changing can be dangerous and should be done by trained professionals using proper tools and procedures. Always read and understand any manufacturer's warnings contained in their customers literature or molded into the tire sidewall. - Serious eye and ear injury may result from not wearing adequate eye and ear protection while repairing tires. - NEVER inflate beyond 275 kPa (40 pounds) pressure to seat beads. Some run flat tires, such as the Goodyear Extended Mobility Tire (EMT) used on the Corvette, may require more than 275 kPa (40 psi) to seat the bead. In such a case, a tire safety cage must be used. Consult the tire manufacturer for its individual repair policy. - NEVER stand, lean or reach over the assembly during inflation. Repairable area on a radial tire. Important - NEVER repair tires worn to the tread indicators 1.59 mm (2/32") remaining depth). - NEVER repair tires with a tread puncture larger than 6.35 mm (1/4"). - NEVER substitute an inner tube for a permissible or non-permissible repair. - NEVER perform an outside-in tire repair (plug only, on the wheel). - Every tire must be removed from the wheel for proper inspection and repair. - Regardless of the type of repair used, the repair must seal the inner liner and fill the injury. - Consult with repair material supplier/manufacturer for repair unit application procedures and repair tools/repair material recommendations. Three basic steps for tire puncture repair: 1. Remove the tire from the wheel for inspection and repair. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 04-03-10-001F > Apr > 10 > Tires/Wheels - Tire Puncture Repair Procedures > Page 13433 2. Fill the injury (puncture) to keep moisture out. 3. Seal the inner liner with a repair unit to prevent air loss. External Inspection 1. Prior to demounting, inspect the tire surface, the valve and the wheel for the source of the leak by using a water and soap solution. Mark the injured area and totally deflate the tire by removing the valve core. 2. Demount the tire from the wheel and place the tire on a well-lighted spreader. Internal Inspection 1. Spread the beads and mark the puncture with a tire crayon. 2. Inspect the inner tire for any signs of internal damage. 3. Remove the puncturing object, noting the direction of the penetration. 4. Probe the injury with a blunt awl in order to determine the extent and direction of the injury. 5. Remove any loose foreign material from the injury. 6. Punctures exceeding 6.35 mm (1/4") should not be repaired. Cleaning 1. Clean the area around the puncture thoroughly with a proper liner cleaner, clean cloth and a scraper. This step serves to remove dirt and mold lubricants to insure proper adhesion and non-contamination of the buffing tool. 2. Refer to information on the product or manufacturer's Material Safety Data Sheet and follow guidelines for handling and disposal. Clean the Injury Channel Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 04-03-10-001F > Apr > 10 > Tires/Wheels - Tire Puncture Repair Procedures > Page 13434 1. Use a proper hand reamer, carbide cutter or drill bit to ream the puncture channel from the inside of the tire in order to clean the injury. 2. Remove steel wires protruding above the liner surface to prevent damage to the repair unit. 3. Consult your repair material supplier for recommended reaming tool(s). Fill the Injury 1. It is necessary to fill the injury channel to provide back up for the repair unit and to prevent moisture from entering the tire fabric and steel wires. 2. (For combination repair/plug units skip this step.) Cement the injured channel and fill the injury from the inside of the tire with the repair plug per repair material manufacturer's recommendations. Without stretching the plug, cut the plug off just above the inside tire surface. 3. Consult your repair material supplier for proper repair material selection. Repair Unit Selection Important Do not install the repair unit in this step.

Center the repair unit over the injury as a reference and outline an area larger than the unit so that buffing will not remove the crayon marks. 2. Remove the repair unit. 3. DO NOT overlap previous or multiple repair units. 4. Consult your repair material supplier for proper repair unit selection. Buffing 1. To prevent contamination and preserve the outline, buff within the marked area thoroughly and evenly with a low speed buffing tool using a fine wire brush or gritted rasp. 2. Buff to a smooth velvet surface (RMA #1 or #2 buffed texture). 3. Use caution not to gouge the inner liner or expose casing fabric. 4. Remove any buffing dust with a vacuum cleaner. 5. Consult your repair material supplier for a proper buffing tool. Cementing Apply chemical cement according to the repair material manufacturer's procedures.

GM's Position on the Use of Nitrogen Gas in Tires General Motors does not oppose the use of purified nitrogen as an inflation gas for tires. We expect the theoretical benefits to be reduced in practical use due to the lack of an existing infrastructure to continuously facilitate inflating tires with nearly pure nitrogen. Even occasional inflation with compressed atmospheric air will negate many of the theoretical benefits. Given those theoretical benefits, practical limitations, and the robust design of GM original equipment TPC tires, the realized benefits to our customer of inflating their tires with purified nitrogen are expected to be minimal. The Promise of Nitrogen: Under Controlled Conditions Recently, nitrogen gas (for use in inflating tires) has become available to the general consumer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. The following benefits under controlled conditions are attributed to nitrogen gas and its unique properties: - A reduction in the expected loss of Tire Pressure over time. - A reduction in the variance of Tire Pressures with temperature changes due to reduction of water vapor concentration. - A reduction of long term rubber degradation due to a decrease in oxygen concentrations. Important These are obtainable performance improvements when relatively pure nitrogen gas is used to inflate tires under controlled conditions. The Promise of Nitrogen: Real World Use Nitrogen inflation can provide some benefit by reducing gas migration (pressure loss) at the molecular level through the tire structure. NHTSA (National Highway Traffic Safety Administration) has stated that the inflation pressure loss of tires can be up to 5% a month. Nitrogen molecules are larger than oxygen molecules and, therefore, are less prone to "seeping" through the tire casing. The actual obtainable benefits of nitrogen vary, based on the physical construction and the materials used in the manufacturing of the tire being inflated. Another potential benefit of nitrogen is the reduced oxidation of tire components. Research has demonstrated that oxygen consumed in the oxidation process of the tire primarily comes from the inflation media. Therefore, it is reasonable to assume that oxidation of tire components can be reduced if the tire is inflated with pure nitrogen. However, only very small amounts of oxygen are required to begin the normal oxidation process. Even slight contamination of the tire inflation gas with compressed atmospheric air during normal inflation pressure maintenance, may negate the benefits of using nitrogen. GM Tire Quality, Technology and Focus of Importance Since 1972, General Motors has designed tires under the TPC (Tire Performance Criteria) specification system, which includes specific requirements that ensure robust tire performance under normal usage. General Motors works with tire suppliers to design and manufacture original equipment tires for GM vehicles. The GM TPC addresses required performance with respect to both inflation pressure retention, and endurance properties for original equipment tires. The inflation pressure retention requirements address availability of oxygen and oxidation concerns, while endurance requirements ensure the mechanical structure of the tire has sufficient strength.

Customer Concerns and Confusion with the Tire Pressure Monitoring (TPM) System The following procedure should be used by dealership service consultants when a customer comes into the service drive with a "low tire light" on or comments on a check tire pressure/low tire pressure/add air to tire or service tire monitor system message. The service consultant should perform the following steps: Procedure Turn the key to ON, without starting the engine. ^ If the low tire light comes on and stays on solid with a check tire pressure/low tire pressure/add air to tire message (on vehicles equipped with DIC), advise the customer: - The system is working properly. - Properly adjusting all tire air pressures to the recommended levels and driving the vehicle will turn the light off (refer to the Tire and Loading Information label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". ^ If the Tire Pressure Monitor (TPM) light blinks for one minute then stays on solid with a service tire monitor system message (on vehicles equipped with DIC): - A TPM system problem exists. The vehicle should be written up accordingly and sent to your service department for further DTC diagnosis and service. - If dashes (--) are displayed in only one or two of the tire pressure readouts, it is likely caused by a previous TPM system relearn that was performed incorrectly due to interference from another vehicle's TPM system during the relearn process (refer to the Important statement later in this bulletin regarding TPM relearn with a Tech 2(R)). - If dashes (--) are displayed in all four of the tire pressure readouts, there is a system problem. Follow the appropriate SI service procedures. ^ If a customer indicates the low tire light comes on for a few minutes when the vehicle is started, then goes off after driving a while, advise the customer: - The system is working properly. - Most likely, air pressure in one or more of the tires is low enough to turn the light on when tires are cold. After driving for a while, tires will heat Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 09-03-16-002A > Apr > 10 > Tire Pressure Monitor - TPM System Message/Service Tips > Page 13447 up, allowing tire air pressure to increase above the threshold causing the light to go off. Properly adjusting all tire air pressures to the recommended levels will correct this (Refer to the Tire and Loading Information Label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". For more detailed information, refer to Corporate Bulletin Number 07-03-16-004C and TPMS Training Course 13044.12T2. Tire Pressure Light At key on, without starting the vehicle: Steady Solid Glowing TPM Indicator If the TPM indicator appears as a steady glowing yellow lamp (as above), the system is functioning properly and you should add air to the tires to correct this condition. Blinking TPM Indicator If the TPM indicator appears as a BLINKING yellow lamp for one minute and then stays on solid, diagnostic service is needed. The Effect of Outside Temperature on Tire Pressures Important: As a rule of thumb, tire pressure will change about 7kPa (1 psi) for every 6°C (10°F) decrease in temperature - Tire pressure will drop when it gets colder outside, and rise when it gets warmer. Under certain situations such as extreme outside temperature changes, the system may bring on a solid light with a check tire pressure message. This should be considered normal and the system is working properly. The light will turn off upon adding the proper amount of air to the tires (refer to the Tire & Loading Information label in the driver's door opening). When properly adjusting tire air pressure, the following steps are important to help optimize the system and prolong bringing a tire pressure light on: ^ Use an accurate, high quality tire pressure gauge. ^ Never set the tire pressure below the specified placard value regardless of tire temperature or ambient temperature. ^ Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will encounter during operation. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > 09-03-16-002A > Apr > 10 > Tire Pressure Monitor - TPM System Message/Service Tips > Page 13448 ^ When adding proper tire air pressure, it is important to remember fluctuations in outside air temperatures and tire temperatures effect tire air pressures. ^ After you have added the proper tire pressure, if the vehicle has a DIC (after the system has updated), check to see if DIC displays are the same readings as the tire pressure gauge used (adjust as necessary). ^ Only perform a TPM sensor re-learn after a tire rotation or system part replacements and use the Tech 2(R) to initiate the relearn whenever possible to avoid invalid sensor I.D. learns. Important: Always take outside temperature and tire temperature into consideration to properly set tire pressures. Foe example, on colder days (20°F/-7°C), if setting tire pressure when the vehicle has been indoors (60°F/16°C) or the tires are warm from being driven, it will be necessary to compensate for the low outside temperature by adding 21-27 kPa (3-4 psi) more then the placecard pressure. At some later time, when the vehicle has been parked outside for a while, the tires will cool off and the pressures will drop back into the placecard range. Important: Recently, nitrogen gas (for use in inflating tires) has become available to the general customer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. Tires inflated with nitrogen gas may exhibit less of a pressure change in response to outside temperature changes. Nitrogen gas inflation is compatible with GM TPM sensors. For additional information, refer to Corporate Service Bulletin 05-03-10-020C. Important: All Models (Except the Pontiac Vibe): Do not perform a TPM relearn at PDI, the system has already been set at the Assembly Plant. Do not perform a TPM relearn after adding air to the tires. The low tire light is similar to the low fuel indicator and adding something (fuel, air) to the vehicle makes that light turn back off again. Note that because of system behavior, some vehicles must be driven a short distance before the sensors recognize the increase in pressure and turns the light off again. Pontiac Vibe Only: Do not use the TPMS reset button to turn off the light. The system will update and light will turn off when all tire pressures have been adjusted followed by short distance drive. Important: All models (except the Pontiac Vibe): Each tire monitor sensor is learned to a specific vehicle corner. When performing a TPM relearn (only after a tire rotation or replacement of a TPM sensor or Module), always use the Tech2(R) to initiate the J 46079 relearned process. Tech 2(R) - initiated relearns lock out other vehicle TPM signals that may be broadcasting in the area. Only signals initiated by the J 46079 tool will be accepted. This method avoids storing false TPM I.D.s and will prevent customers from returning with dashes (--) displayed in tire pressure readouts and/or a flashing tire pressure monitor (TPM) light. Checking the four TPM I.D.s with the Tech 2(R) prior to and following relearn to verify they are the same can prevent invalid I.D. learns. Pontiac Vibe Only: Tire Monitor Sensors are not learned to a specific vehicle corner. Do not perform a TPM Reset after tire rotation. The TPMS Reset button must only be used during pre-delivery inspection by the dealer to initialize the system (after all tire pressures have been adjusted properly) or when a Tire Pressure Monitor System component is replaced. The J 46079 tool does not work on Vibe TPM sensors. A TPMS relearn on Vibe must be preformed with a Tech 2(R) to set the TPMS Module in learn mode. The TPMS sensor IDs are entered through the Tech 2(R). Refer to SI for further Vibe TPMS information. Labor Operation and Repair Order/Warranty System Claim Required Documentation Important: The ONLY time labor operation E0726 or E0722 should be used is to diagnose for a system issue. That should ONLY occur if, at key ON, without starting the engine, the Tire Pressure Monitor (TPM) blinks for one minute and then stays on solid with a Service Tire Monitor System message (on vehicles equipped with a DIC) If that occurs, a TPM system problem exists and the system will have set a DTC. If one of these operastions is used, the following Repair Order and Warranty System documentation are required: ^ Document the customer complaint on the Repair Order. ^ Document the TPMS DTC that has set on the Repair Order. ^ Enter the TPMS DTC in the Warranty System (WINS) in the Failure Code/DTC field on the claim submission (refer to the Claims Processing Manual, Section IV, Warranty claim Data, Page 6, Item G). If the above information is not documented on the Repair Order and Warranty System, the claim may be rejected. If the Warranty Parts Center (WPC) generates a request, this repair order documentation must be sent back.

Please discard Corporate Bulletin Number 07-03-10-008A (Section 03 - Suspension). This bulletin provides information regarding the normal tire wear condition of slight or mild tire feathering and recommended practices. If a vehicle comes into a dealership with a concern of slight or mild feathering-type wear on the tires, review with the customer their past tire rotation history. Tires should be rotated every 8,000 to 13,000 km (5,000 to 8,000 mi) for applicable vehicles with tires where a tire rotation is possible or recommended. Refer to Corporate Bulletin Number 05-03-10-015B for information on tire rotation for vehicles with different front/rear tire/wheel sizes. SOME TIRE FEATHERING IS A NORMAL PART OF TIRE WEAR AND THROUGH PROPER TIRE ROTATION AND INFLATION, THIS TIRE WEAR CAN BE MINIMIZED AND TIRE LIFE MAXIMIZED. If the customer has not rotated the tires within the last 8,000 to 13,000 km (5,000 to 8,000 mi), a tire rotation in the modified X-pattern is necessary to clean-up the feathering, rather than placing the vehicle on the alignment machine.

Important: ^ Adjustment of tire pressure for a customer with a Low Tire Pressure Monitor (TPM) light on and no codes in the TPM system is NOT a warrantable repair. Claims to simply adjust the tire pressure will be rejected. ^ ALL tires (including the spare tire) MUST be set to the recommended inflation pressure stated on the vehicle's tire placard (on driver's door) during the PRE-DELIVERY INSPECTION (PDI). Recommended inflation pressure is not the pressure printed on tire sidewall. ^ Tires may be over-inflated from the assembly plant due to the mounting process. ^ Generally a 5.6°C (10°F) temperature change will result in (is equivalent to) a 6.9 kPa (1 psi) tire pressure change. ^ 2008-2009 HUMMER H2 Only - The H2 comes standard with Light Truck "D" Load Range tires with a recommended cold inflation pressure of 289 kPa (42 psi). These tires will alert the driver to a low pressure situation at roughly 262 kPa (38 psi) due to a requirement in FMVSS 138 which specifies a Minimum Activation Pressure for each tire type. This creates a relatively narrow window of "usable" pressure values and the warning will be more sensitive to outside temperature changes during the colder months. As with other cold temperature/tire pressure issues, there is nothing wrong with the system itself. If a vehicle is brought in with this concern, check for tire damage and set all tires to the Recommended Cold Inflation Pressure shown on the vehicle placard. Accurate tire pressures ensure the safe handling and appropriate ride characteristics of GM cars and trucks. It is critical that the tire pressure be adjusted to the specifications on the vehicle¡C■s tire placard during PDI. Ride, handling and road noise concerns may be caused by improperly adjusted tire pressure. The first step in the diagnosis of these concerns is to verify that the tires are inflated to the correct pressures. The recommended tire inflation pressure is listed on the vehicle¡C■s tire placard. The tire placard is located on the driver¡C■s side front or rear door edge, center pillar, or the rear compartment lid. Tip ^ Generally a 5.6°C (10°F) temperature increase will result in (is equivalent to) a 6.9 kPa (1 psi) tire pressure increase. ^ The definition of a "cold" tire is one that has been sitting for at least 3 hours, or driven no more than 1.6 km (1 mi). ^ On extremely cold days, if the vehicle has been indoors, it may be necessary to compensate for the low external temperature by adding additional air to the tire during PDI. ^ During cold weather, the Tire Pressure Monitor (TPM) indicator light (a yellow horseshoe with an exclamation point) may illuminate. If this indicator turns off after the tires warm up (reach operating temperature), the tire pressure should be reset to placard pressure at the cold temperature. ^ The TPM system will work correctly with nitrogen in tires. ^ The TPM system is compatible with the GM Vehicle Care Tire Sealant but may not be with other commercially available sealants. Important: ^ Do not use the tire pressure indicated on the tire itself as a guide.

The driver information center (DIC), if equipped, will also display a SERVICE TIRE MONITOR type message. When the road tire is repaired and reinstalled in the original location, the TPM indicator icon illumination and DIC message may remain displayed until the DTC is cleared. To ensure that the TPM indicator and the DIC message are cleared after service, it is necessary to clear any TPM DTCs using a scan tool. If a scan tool is unavailable, performing the TPM relearn procedure using a TPM diagnostic tool will provide the same results. It is advised to perform the relearn procedure away from other vehicles to prevent picking up a stray sensor signal. If one or more of the TPM sensors are missing or damaged and have been replaced, then the relearn procedure must be performed.

GM's Position on the Use of Nitrogen Gas in Tires General Motors does not oppose the use of purified nitrogen as an inflation gas for tires. We expect the theoretical benefits to be reduced in practical use due to the lack of an existing infrastructure to continuously facilitate inflating tires with nearly pure nitrogen. Even occasional inflation with compressed atmospheric air will negate many of the theoretical benefits. Given those theoretical benefits, practical limitations, and the robust design of GM original equipment TPC tires, the realized benefits to our customer of inflating their tires with purified nitrogen are expected to be minimal. The Promise of Nitrogen: Under Controlled Conditions Recently, nitrogen gas (for use in inflating tires) has become available to the general consumer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. The following benefits under controlled conditions are attributed to nitrogen gas and its unique properties: - A reduction in the expected loss of Tire Pressure over time. - A reduction in the variance of Tire Pressures with temperature changes due to reduction of water vapor concentration. - A reduction of long term rubber degradation due to a decrease in oxygen concentrations. Important These are obtainable performance improvements when relatively pure nitrogen gas is used to inflate tires under controlled conditions. The Promise of Nitrogen: Real World Use Nitrogen inflation can provide some benefit by reducing gas migration (pressure loss) at the molecular level through the tire structure. NHTSA (National Highway Traffic Safety Administration) has stated that the inflation pressure loss of tires can be up to 5% a month. Nitrogen molecules are larger than oxygen molecules and, therefore, are less prone to "seeping" through the tire casing. The actual obtainable benefits of nitrogen vary, based on the physical construction and the materials used in the manufacturing of the tire being inflated. Another potential benefit of nitrogen is the reduced oxidation of tire components. Research has demonstrated that oxygen consumed in the oxidation process of the tire primarily comes from the inflation media. Therefore, it is reasonable to assume that oxidation of tire components can be reduced if the tire is inflated with pure nitrogen. However, only very small amounts of oxygen are required to begin the normal oxidation process. Even slight contamination of the tire inflation gas with compressed atmospheric air during normal inflation pressure maintenance, may negate the benefits of using nitrogen. GM Tire Quality, Technology and Focus of Importance Since 1972, General Motors has designed tires under the TPC (Tire Performance Criteria) specification system, which includes specific requirements that ensure robust tire performance under normal usage. General Motors works with tire suppliers to design and manufacture original equipment tires for GM vehicles. The GM TPC addresses required performance with respect to both inflation pressure retention, and endurance properties for original equipment tires. The inflation pressure retention requirements address availability of oxygen and oxidation concerns, while endurance requirements ensure the mechanical structure of the tire has sufficient strength. This combination has provided our customers with tires that maintain their structural integrity throughout their useful treadlife under normal operating conditions.

Please discard Corporate Bulletin Number 04-03-10-001E (Section 03 - Suspension). This bulletin covers puncture repair procedures for passenger car and light duty truck radial tires in the tread area only. The tire manufacturer must be contacted for its individual repair policy and whether or not the speed rating is retained after repair. Caution - Tire changing can be dangerous and should be done by trained professionals using proper tools and procedures. Always read and understand any manufacturer's warnings contained in their customers literature or molded into the tire sidewall. - Serious eye and ear injury may result from not wearing adequate eye and ear protection while repairing tires. - NEVER inflate beyond 275 kPa (40 pounds) pressure to seat beads. Some run flat tires, such as the Goodyear Extended Mobility Tire (EMT) used on the Corvette, may require more than 275 kPa (40 psi) to seat the bead. In such a case, a tire safety cage must be used. Consult the tire manufacturer for its individual repair policy. - NEVER stand, lean or reach over the assembly during inflation. Repairable area on a radial tire. Important - NEVER repair tires worn to the tread indicators 1.59 mm (2/32") remaining depth). - NEVER repair tires with a tread puncture larger than 6.35 mm (1/4"). - NEVER substitute an inner tube for a permissible or non-permissible repair. - NEVER perform an outside-in tire repair (plug only, on the wheel). - Every tire must be removed from the wheel for proper inspection and repair. - Regardless of the type of repair used, the repair must seal the inner liner and fill the injury. - Consult with repair material supplier/manufacturer for repair unit application procedures and repair tools/repair material recommendations. Three basic steps for tire puncture repair: 1. Remove the tire from the wheel for inspection and repair. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > Page 13465 2. Fill the injury (puncture) to keep moisture out. 3. Seal the inner liner with a repair unit to prevent air loss. External Inspection 1. Prior to demounting, inspect the tire surface, the valve and the wheel for the source of the leak by using a water and soap solution. Mark the injured area and totally deflate the tire by removing the valve core. 2. Demount the tire from the wheel and place the tire on a well-lighted spreader. Internal Inspection 1. Spread the beads and mark the puncture with a tire crayon. 2. Inspect the inner tire for any signs of internal damage. 3. Remove the puncturing object, noting the direction of the penetration. 4. Probe the injury with a blunt awl in order to determine the extent and direction of the injury. 5. Remove any loose foreign material from the injury. 6. Punctures exceeding 6.35 mm (1/4") should not be repaired. Cleaning 1. Clean the area around the puncture thoroughly with a proper liner cleaner, clean cloth and a scraper. This step serves to remove dirt and mold lubricants to insure proper adhesion and non-contamination of the buffing tool. 2. Refer to information on the product or manufacturer's Material Safety Data Sheet and follow guidelines for handling and disposal. Clean the Injury Channel Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > Page 13466 1. Use a proper hand reamer, carbide cutter or drill bit to ream the puncture channel from the inside of the tire in order to clean the injury. 2. Remove steel wires protruding above the liner surface to prevent damage to the repair unit. 3. Consult your repair material supplier for recommended reaming tool(s). Fill the Injury 1. It is necessary to fill the injury channel to provide back up for the repair unit and to prevent moisture from entering the tire fabric and steel wires. 2. (For combination repair/plug units skip this step.) Cement the injured channel and fill the injury from the inside of the tire with the repair plug per repair material manufacturer's recommendations. Without stretching the plug, cut the plug off just above the inside tire surface. 3. Consult your repair material supplier for proper repair material selection. Repair Unit Selection Important Do not install the repair unit in this step. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > Page 13467 1. Center the repair unit over the injury as a reference and outline an area larger than the unit so that buffing will not remove the crayon marks. 2. Remove the repair unit. 3. DO NOT overlap previous or multiple repair units. 4. Consult your repair material supplier for proper repair unit selection. Buffing 1. To prevent contamination and preserve the outline, buff within the marked area thoroughly and evenly with a low speed buffing tool using a fine wire brush or gritted rasp. 2. Buff to a smooth velvet surface (RMA #1 or #2 buffed texture). 3. Use caution not to gouge the inner liner or expose casing fabric. 4. Remove any buffing dust with a vacuum cleaner. 5. Consult your repair material supplier for a proper buffing tool. Cementing Apply chemical cement according to the repair material manufacturer's procedures. Repair Unit Application Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Technical Service Bulletins > Technical Service Bulletins for Tires: > Page 13468 1. The tire must be in the relaxed position when the repair unit is installed (Do not spread the beads excessively). Two-Piece Plug and Repair Units 1. If applicable, install the repair unit so that the alignment is correct. 2. Center the repair unit over the injury and stitch down thoroughly with the stitching tool, working from the center out. 3. Being careful not to stretch the plug material, cut the plug flush with the outer tread. Combination Repair/Plug Units 1. Pull the plug through the injury until the repair just reaches the liner. Stitch down thoroughly. 2. Follow the repair material manufacturer's recommendations for further installation instructions. 2. Consult your repair material supplier for the proper stitching tool.

Incorrect tire pressures, or under-inflated tires, can cause the following conditions: * Vehicle handling concerns * Poor fuel economy * Shortened tire life * Tire overloading Inspect the tire pressure when the following conditions apply: * The vehicle has been sitting at least 3 hours. * The vehicle has not been driven for more than 1.6 km (1 mi). * The tires are cool. Inspect the tires monthly or before any extended trip. Adjust the tire pressure to the specifications on the tire label. Install the valve caps or the extensions on the valves. The caps or the extensions keep out dust and water. The kilopascal (kPa) is the metric term for pressure. The tire pressure may be printed in both kilopascal (kPa) and psi. One psi equals 6.9 kPa. Inflation Pressure Conversation (Kilopascals To PSI) Tires with a higher than recommended pressure can cause the following conditions: * A hard ride * Tire bruising * Rapid tread wear at the center of the tire Tires with a lower than recommended pressure can cause the following conditions: * A tire squeal on turns * Hard steering * Rapid wear and uneven wear on the edge of the tread * Tire rim bruises and tire rim rupture * Tire cord breakage * High tire temperatures * Reduced vehicle handling * High fuel consumption * Soft riding Unequal pressure on the same axle can cause the following conditions: Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Description and Operation > Tread Wear Indicators Description > Page 13473 * Uneven braking * Steering lead * Reduced vehicle handling Refer to the Tire Placard for specific tire and wheel applications and tire pressures.

These tires qualify as snow tires, with a higher than average rating for snow traction than the non-all season radial tires previously used. Other performance areas, such as wet traction, rolling resistance, tread life, and air retention, are also improved. This is done by improvements in both tread design and tread compounds. These tires are identified by an M + S molded in the tire side wall after the tire size. The suffix MS is also molded in the tire side wall after the TPC specification number.

Three basic steps for tire puncture repair: 1. Remove the tire from the wheel for inspection and repair. 2. Fill the injury (puncture) to keep moisture out. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 13478 3. Seal the inner liner with a repair unit to prevent air loss. External Inspection 1. Prior to demounting, inspect the tire surface, the valve and the wheel for the source of the leak by using a water and soap solution. Mark the injured area and totally deflate the tire by removing the valve core. 2. Demount the tire from the wheel and place the tire on a well-lighted spreader. Internal Inspection 1. Spread the beads and mark the puncture with a tire crayon. 2. Inspect the inner tire for any signs of internal damage. 3. Remove the puncturing object, noting the direction of the penetration. 4. Probe the injury with a blunt awl in order to determine the extent and direction of the injury. 5. Remove any loose foreign material from the injury. 6. Punctures exceeding 6.35 mm (1/4 in) should not be repaired. Cleaning Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 13479 1. Clean the area around the puncture thoroughly with a proper liner cleaner, clean cloth and a scraper. This step serves to remove dirt and mold lubricants to insure proper adhesion and non-contamination of the buffing tool. 2. Refer to information on the product or manufacturer's Material Safety Data Sheet and follow guidelines for handling and disposal. Clean the Injury Channel 1. Use a proper hand reamer, carbide cutter or drill bit to ream the puncture channel from the inside of the tire in order to clean the injury. 2. Remove steel wires protruding above the liner surface to prevent damage to the repair unit. 3. Consult your repair material supplier for recommended reaming tool(s). Fill the Injury Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 13480 1. It is necessary to fill the injury channel to provide back up for the repair unit and to prevent moisture from entering the tire fabric and steel wires. 2. For combination repair/plug units skip this step. Cement the injured channel and fill the injury from the inside of the tire with the repair plug per repair material manufacturer's recommendations. Without stretching the plug, cut the plug off just above the inside tire surface. 3. Consult your repair material supplier for proper repair material selection. Repair Unit Selection Important: Do not install the repair unit in this step. 1. Center the repair unit over the injury as a reference and outline an area larger than the unit so that buffing will not remove the crayon marks. 2. Remove the repair unit. 3. DO NOT overlap previous or multiple repair units. 4. Consult your repair material supplier for proper repair unit selection. Buffing Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 13481 1. To prevent contamination and preserve the outline, buff within the marked area thoroughly and evenly with a low speed buffing tool using a fine wire brush or gritted rasp. 2. Buff to a smooth velvet surface (RMA #1 or #2 buffed texture). 3. Use caution not to gouge the inner liner or expose casing fabric. 4. Remove any buffing dust with a vacuum cleaner. 5. Consult your repair material supplier for a proper buffing tool. Cementing Apply chemical cement according to the repair material manufacturer's procedures. Repair Unit Application Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 13482 The tire must be in the relaxed position when the repair unit is installed. Do not spread the beads excessively. Two-Piece Plug and Repair Units 1. If applicable, install the repair unit so that the alignment is correct. 2. Center the repair unit over the injury and stitch down thoroughly with the stitching tool, working from the center out. 3. Being careful not to stretch the plug material, cut the plug flush with the outer tread. Combination Repair/Plug Units 1. Pull the plug through the injury until the repair just reaches the liner. Stitch down thoroughly. 2. Follow the repair material manufacturer's recommendations for further installation instructions. Consult your repair material supplier for the proper stitching tool. Safety Cage Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 13483 Some run flat tires, such as the Goodyear Extended Mobility Tire (EMT) used on the Corvette, may require more than 275 kPa (40 psi) to seat the bead. In such a case, a tire safety cage must be used. Consult the tire manufacturer for its individual repair policy. Final Inspection 1. After remounting and inflating the tire, check both beads, the repair and the valve with a water and soap solution in order to detect leaks. 2. If the tire continues to lose air, the tire must be demounted and reinspected. 3. Balance the tire and wheel assembly. Refer to Tire and Wheel Assembly Balancing - Off Vehicle. Tire Rotation Tire Rotation Rotate the tires and wheels at frequent intervals to equalize wear. Refer to Maintenance Schedule (North American Emissions). In addition to scheduled rotation, rotate the tire and wheel whenever uneven tire wear is noticed. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 13484 Radial tires tend to wear faster in the shoulder area, particularly in front positions. Radial tires in non-drive locations may develop an irregular wear pattern that may increase tire noise. This makes regular rotation especially necessary. Refer to Tire and Wheel Removal and Installation. Always use a 4-wheel rotation. After rotation, check the wheel nuts for specified torque. Then, set the tire pressure. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Tires > Component Information > Service and Repair > Procedures > Page 13485 Tires: Removal and Replacement Tire Mounting and Dismounting Notice: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result. Notice: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel. Notice: Damage to either the tire bead or the wheel mounting holes can result from the use of improper wheel attachment or tire mounting procedures. It takes up to 70 seconds for all of the air to completely exhaust from a large tire. Failure to follow the proper procedures could cause the tire changer to put enough force on the tire to bend the wheel at the mounting surface. Such damage may result in vibration and/or shimmy, and under severe usage lead to wheel cracking. 1. Deflate the tire completely. Important: Rim-clamp European-type tire changers are recommended. 2. Use the tire changer in order to remove the tire from the wheel. 3. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats. Notice: When mounting the tires, use an approved tire mounting lubricant. DO NOT use silicon or corrosive base compounds to lubricate the tire bead and the wheel rim. A silicon base compound can cause the tire to slip on the rim. A corrosive type compound can cause tire or rim deterioration. 4. Apply an approved Lubricant to the tire bead and the wheel rim. 5. Use the tire changer in order to install the tire to the wheel. Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, relubricate the beads and reinflate. Overinflation may cause the bead to break and cause serious personal injury. 6. Inflate the tire to the proper air pressure. 7. Ensure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.

Please discard Corporate Bulletin Number 00-03-10-006E (Section 03 - Suspension). Important - Before measuring tires on equipment such as the Hunter GSP9700, the vehicle MUST be driven a minimum of 16 km (10 mi) to ensure removal of any flat-spotting. Refer to Corporate Bulletin Number 03-03-10-007E - Tire/Wheel Characteristics of GM Original Equipment Tires. - Equipment such as the Hunter GSP9700 MUST be calibrated prior to measuring tire/wheel assemblies for each vehicle. The purpose of this bulletin is to provide guidance to GM dealers when using tire force variation measurement equipment, such as the Hunter GSP9700. This type of equipment can be a valuable tool in diagnosing vehicle ride concerns. The most common ride concern involving tire radial force variation is highway speed shake on smooth roads. Tire related smooth road highway speed shake can be caused by three conditions: imbalance, out of round and tire force variation. These three conditions are not necessarily related. All three conditions must be addressed. Imbalance is normally addressed first, because it is the simpler of the three to correct. Off-vehicle, two plane dynamic wheel balancers are readily available and can accurately correct any imbalance. Balancer calibration and maintenance, proper attachment of the wheel to the balancer, and proper balance weights, are all factors required for a quality balance. However, a perfectly balanced tire/wheel assembly can still be "oval shaped" and cause a vibration. Before balancing, perform the following procedures. Tire and Wheel Diagnosis 1. Set the tire pressure to the placard values. 2. With the vehicle raised, ensure the wheels are centered on the hub by loosening all wheel nuts and hand-tightening all nuts first by hand while shaking the wheel, then torque to specifications using a torque wrench, NOT a torque stick. 3. Visually inspect the tires and the wheels. Inspect for evidence of the following conditions and correct as necessary: - Missing balance weights - Bent rim flange - Irregular tire wear - Incomplete bead seating - Tire irregularities (including pressure settings) - Mud/ice build-up in wheel - Stones in the tire tread - Remove any aftermarket wheels and/or tires and restore vehicle to original condition prior to diagnosing a smooth road shake condition. 4. Road test the vehicle using the Electronic Vibration Analyzer (EVA) essential tool. Drive for a sufficient distance on a known, smooth road surface to duplicate the condition. Determine if the vehicle is sensitive to brake apply. If the brakes are applied lightly and the pulsation felt in the steering wheel increases, refer to the Brakes section of the service manual that deals with brake-induced pulsation. If you can start to hear the vibration as a low boom noise (in addition to feeling it), but cannot see it, the vehicle likely has a first order (one pulse per propshaft revolution) driveline vibration. Driveline first order vibrations are high enough in frequency that most humans can start to hear them at highway speeds, but are too high to be able to be easily seen. These issues can be caused by driveline imbalance or misalignment. If the vehicle exhibits this low boom and the booming pulses in-and-out on a regular basis (like a throbbing), chances are good that the vehicle could have driveline vibration. This type Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > Customer Interest: > 00-03-10-006F > May > 10 > Wheels/Tires - Tire Radial Force Variation (RFV) > Page 13494 of vibration is normally felt more in the "seat of the pants" than the steering wheel. 5. Next, record the Hertz (Hz) reading as displayed by the EVA onto the tire data worksheet found at the end of this bulletin. This should be done after a tire break-in period of at least 16 km (10 mi) at 72 km/h (45 mph) or greater, in order to eliminate any possible tire flat-spotting. This reading confirms what the vehicle vibration frequency is prior to vehicle service and documents the amount of improvement occurring as the result of the various steps taken to repair. Completing the Steering Wheel Shake Worksheet below is required. A copy of the completed worksheet must be saved with the R.O. and a copy included with any parts returned to the Warranty Parts Center for analysis. A reading of 35 to 50 Hz typically indicates a first order propshaft vibration. If this is the situation, refer to Corporate Bulletin Number 08-07-30-044D. Generally, a reading between 10 and 20 Hz indicates a tire/wheel vibration and if this is the reading obtained, continue using this bulletin. If the tire 1st order vibration goes away and stays away during this evaluation, the cause is likely tire flat-spotting. Tire flat-spotting vibration may come and go at any speed over 72 km/h (45 mph) during the first 10 minutes of operation, if vibration continues after 10 minutes of driving at speeds greater than 72 km/h (45 mph), tire flat-spotting can be ruled out as the cause for vibration. 6. If flat-spotting is the cause, provide the explanation that this has occurred due to the vehicle being parked for long periods of time and that the nature of the tire is to take a set. Refer to Corporate Bulletin Number 03-03-10-007E: Information on Tire/Wheel Characteristics (Vibration, Balance, Shake, Flat Spotting) of GM Original Equipment Tires. 7. If the road test indicates a shake/vibration exists, check the imbalance of each tire/wheel assembly on a known, calibrated, off-car dynamic balancer.Make sure the mounting surface of the wheel and the surface of the balancer are absolutely clean and free of debris. Be sure to chose the proper cone/collet for the wheel, and always use the pilot bore for centering. Never center the wheel using the hub-cap bore since it is not a precision machined surface. If any assembly calls for more than 1/4 ounce on either rim flange, remove all balance weights and rebalance to as close to zero as possible. If you can see the vibration (along with feeling it) in the steering wheel (driving straight without your hands on the wheel), it is very likely to be a tire/wheel first order (one pulse per revolution) disturbance. First order disturbances can be caused by imbalance as well as non-uniformities in tires, wheels or hubs. This first order frequency is too low for a human to hear, but if the amplitude is high enough, it can be seen. If a vibration or shake still exists after balancing, any out of round conditions, of the wheel, and force variation conditions of the tire, must be addressed. Equipment such as the Hunter GSP9700 can address both (it is also a wheel balancer). Tire radial force vibration (RFV) can be defined as the amount of stiffness variation the tire will produce in one revolution under a constant load. Radial force variation is what the vehicle feels because the load (weight) of the vehicle is always on the tires. Although free runout of tires (not under load) is not always a good indicator of a smooth ride, it is critical that total tire/wheel assembly runout be within specification. Equipment such as the Hunter GSP9700 loads the tire, similar to on the vehicle, and measures radial force variation of the tire/wheel assembly. Note that the wheel is affecting the tire's RFV measurement at this point. To isolate the wheel, its runout must be measured. This can be easily done on the Hunter, without the need to set up dial indicators. If the wheel meets the runout specification, the tire's RFV can then be addressed. After measuring the tire/wheel assembly under load, and the wheel alone, the machine then calculates (predicts) the radial force variation of the tire. However, because this is a prediction that can include mounting inaccuracies, and the load wheel is much smaller in diameter than used in tire production, this type of service equipment should NOT be used to audit new tires. Rather, it should be used as a service diagnostic tool to minimize radial force variation of the tire/wheel assembly. Equipment such as the Hunter GSP9700 does an excellent job of measuring wheel runout, and of finding the low point of the wheel (for runout) and the high point of the tire (for radial force variation). This allows the tire to be matched mounted to the wheel for lowest tire/wheel assembly force variation. The machine will simplify this process into easy steps. The following assembly radial force variation numbers should be used as a guide: When measuring RFV and match mounting tires perform the following steps. Measuring Wheel Runout and Assembly Radial Force Variation Important The completed worksheet at the end of this bulletin must be attached to the hard copy of the repair order. - Measure radial force variation and radial runout. - If a road force/balancing machine is used, record the radial force variation (RFV) on the worksheet at the end of this bulletin. It may be of benefit to have the lowest RFV assembly to the front left corner. If the machine is not available and the EVA data suggests there is an issue, swap the tire and wheel assemblies from the front to the back. Re-check on the EVA and if the problem still exists, test another vehicle to find tires that do not exhibit the same frequency and swap those tires onto the subject vehicle. - If a runout/balancing machine is used, record the radial runout of the tire/wheel assemblies on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies are more than.040 in (1.02 mm), match mount the tire to the wheel to get below.040 in (1.02 mm). For sensitive customers, readings of 0.030 inch (0.76 mm) or less are preferable, it may also be of benefit to have the lowest runout assembly to the front left corner. If the machine is not available and the EVA data suggests there is an issue, swap the tire and wheel assemblies from the front to the back. Re-check on the EVA and if the problem still exists, test another vehicle to find tires that do not exhibit the same frequency and swap those tires Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > Customer Interest: > 00-03-10-006F > May > 10 > Wheels/Tires - Tire Radial Force Variation (RFV) > Page 13495 onto the subject vehicle. - After match mounting, the tire/wheel assembly must be rebalanced. If match mounting tires to in-spec wheels produces assembly values higher than these, tire replacement may be necessary. Replacing tires at lower values will probably mean good tires are being condemned. Because tires can sometimes become temporarily flat-spotted, which will affect force variation, it is important that the vehicle be driven at least 16 km (10 mi) prior to measuring. Tire pressure must also be adjusted to the usage pressure on the vehicle's tire placard prior to measuring. Most GM vehicles will tolerate radial force variation up to these levels. However, some vehicles are more sensitive, and may require lower levels. Also, there are other tire parameters that equipment such as the Hunter GSP9700 cannot measure that may be a factor. In such cases, TAC should be contacted for further instructions. Important - When mounting a GM wheel to a wheel balancer/force variation machine, always use the wheel's center pilot hole. This is the primary centering mechanism on all GM wheels; the bolt holes are secondary. Usually a back cone method to the machine should be used. For added accuracy and repeatability, a flange plate should be used to clamp the wheel onto the cone and machine. This system is offered by all balancer manufacturers in GM's dealer program. - Any type of service equipment that removes tread rubber by grinding, buffing or truing is NOT recommended, and may void the tire warranty. However, tires may have been ground by the tire company as part of their tire manufacturing process. This is a legitimate procedure.

Cause Abrasive elements in the environment may intrude between the tire and wheel at the bead seat. There is always some relative motion between the tire and wheel (when the vehicle is driven) and this motion may cause the abrasive particles to wear the wheel and tire materials. As the wear continues, there may also be intrusion at the tire/wheel interface by corrosive media from the environment. Eventually a path for air develops and a 'slow' leak may ensue. This corrosion may appear on the inboard or outboard bead seating surface of the wheel. This corrosion will not be visible until the tire is dismounted from the wheel.

For issues related to porosity of the wheel casting that may result in an air leak, please refer to Corporate Bulletin Number 05-03-10-006F - Low Tire Pressure, Leaking Cast Aluminum Wheels (Repair with Adhesive Sealant) Correction In most cases, this type of air loss can be corrected by following the procedure below. Important DO NOT replace a wheel for slow air loss unless you have evaluated and/or tried to repair the wheel with the procedure below. Notice The repair is no longer advised or applicable for chromed aluminum wheels. 1. Remove the wheel and tire assembly for diagnosis. Refer to Tire and Wheel Removal and Installation in SI. 2. After a water dunk tank leak test, if you determine the source of the air leak to be around the bead seat of the wheel, dismount the tire to examine the bead seat. Shown below is a typical area of bead seat corrosion.Typical Location of Bead Seat Corrosion Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > Customer Interest: > 08-03-10-006C > Apr > 10 > Tires/Wheels - Tire Slowly Goes Flat/Warning Light ON > Page 13506 Important Other forms of slow air leaks are possible. If the body of the tire, valve stem and wheel flange show no signs of air seepage, refer to Corporate Bulletin Number 05-03-10-003D for additional information on possible wheel porosity issues. 3. Bead seat corrosion is identified by what appears like blistering of the wheel finish, causing a rough or uneven surface that is difficult for the tire to maintain a proper seal on. Below is a close-up photo of bead seat corrosion on an aluminum wheel that was sufficient to cause slow air loss. Close-Up of Bead Seat Corrosion 4. If corrosion is found on the wheel bead seat, measure the affected area as shown below. - For vehicles with 32,186 km (20,000 mi) or less, the total allowable combined linear area of repairable corrosion is 100 mm (4 in) or less. If the total area(s) of corrosion exceed these dimensions, the wheel should be replaced. - For vehicles that have exceeded 32,186 km (20,000 mi), the total allowable combined linear area of repairable corrosion is 200 mm (8 in) or less. If the total area(s) of corrosion exceed these dimensions, the wheel should be replaced. 5. In order to correct the wheel leak, use a clean-up (fine cut) sanding disc or biscuit to remove the corrosion and any flaking paint. You should remove the corrosion back far enough until you reach material that is stable and firmly bonded to the wheel. Try to taper the edge of any flaking paint as best you can in order to avoid sharp edges that may increase the chance of a leak reoccurring. The photo below shows an acceptable repaired surface. Notice Corrosion that extends up the lip of the wheel, where after the clean-up process it would be visible with the tire mounted, is only acceptable on the inboard flange. The inboard flange is not visible with the wheel assembly in the mounted position. If any loose coatings or corrosion extend to the visible surfaces on the FACE of the wheel, that wheel must be replaced. Important Remove ONLY the material required to eliminate the corrosion from the bead seating surface. DO NOT remove excessive amounts of material. ALWAYS keep the sealing surface as smooth and level as possible.

Once the corrosion has been eliminated, you should coat the repaired area with a commercially available tire sealant such as Patch Brand Bead Sealant or equivalent. Commercially available bead sealants are black rubber-like coatings that will permanently fill and seal the resurfaced bead seat. At 21°C (70°F) ambient temperature, this sealant will set-up sufficiently for tire mounting in about 10 minutes.Coated and Sealed Bead Seat 7. Remount the tire and install the repaired wheel and tire assembly. Refer to Tire and Wheel Removal and Installation in SI.

Figure 1 Chemical staining in most cases results from acid based cleaners (refer to Figure 1 for an example). These stains are frequently milky, black, or greenish in appearance. They result from using cleaning solutions that contain acids on chrome wheels. Soap and water is usually sufficient to clean wheels. If the customer insists on using a wheel cleaner they should only use one that specifically states that it is safe for chromed wheels and does not contain anything in the following list. (Dealers should also survey any products they use during prep or normal cleaning of stock units for these chemicals.) - Ammonium Bifluoride (fluoride source for dissolution of chrome) - Hydrofluoric Acid (directly dissolves chrome) - Hydrochloric Acid (directly dissolves chrome) - Sodium Dodecylbenzenesulfonic Acid - Sulfamic Acid - Phosphoric Acid - Hydroxyacetic Acid Notice Many wheel cleaner instructions advise to take care to avoid contact with painted surfaces. Most customers think of painted surfaces as the fenders, quarter panels and other exterior sheet metal. Many vehicles have painted brake calipers. Acidic wheel cleaners may craze, crack, or discolor the paint on the brake calipers. Damage from wheel cleaners is not covered under the vehicle new car warranty. Soap and water applied with a soft brush is usually all that is required to clean the calipers. Whenever any wheel cleaner is used, it must be THOROUGHLY rinsed off of the wheel with clean, clear water. Special care must be taken to rinse under the hub cap, balance weights, wheel nuts, lug nut caps, between the wheel cladding and off the back side of the wheel. Wheels returned to the Warranty Parts Center (WPC) that exhibit damage from wheel cleaners most often have the damage around and under the wheel weight where the cleaner was incompletely flushed away. Notice Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins: > 00-03-10-002F > Apr > 11 > Wheels - Chrome Wheel Staining/Pitting/Corrosion > Page 13514 Do not use cleaning solutions that contain hydrofluoric, oxalic and most other acids on chrome wheels (or any wheels). If the customer is unsure of the chemical make-up of a particular wheel cleaner, it should be avoided. For wheels showing signs of milky staining from acidic cleaners, refer to Customer Assistance and Instructions below. Warranty of Stained Chrome Wheels Stained wheels are not warrantable. Most acid based cleaners will permanently stain chrome wheels. Follow-up with dealers has confirmed that such cleaners were used on wheels that were returned to the Warranty Parts Center (WPC). Any stained wheels received by the WPC will be charged back to the dealership. To assist the customer, refer to Customer Assistance and Instructions below. Pitting or Spotted Appearance of Chrome Wheels Figure 2 A second type or staining or finish disturbance may result from road chemicals, such as calcium chloride used for dust control of unpaved roads. The staining will look like small pitting (refer to Figure 2). This staining will usually be on the leading edges of each wheel spoke, but may be uniformly distributed. If a vehicle must be operated under such conditions, the chrome wheels should be washed with mild soap and water and thoroughly rinsed as soon as conveniently possible. Important Road chemicals, such as calcium chloride used for dust control of unpaved roads, can also stain chrome wheels. The staining will look like small pitting. This staining will usually be on the leading edges of each wheel spoke. This is explained by the vehicle traveling in the forward direction while being splashed by the road chemical. If a vehicle must be operated under such conditions, the chrome wheels should be washed with mild soap and water and thoroughly rinsed as soon as conveniently possible. Warranty of Pitted or Spotted Chrome Wheels Wheels returned with pitting or spotting as a result of road chemicals may be replaced one time. Damage resulting from contact with these applied road chemicals is corrosive to the wheels finish and may cause damage if the wheels are not kept clean. Important Notify the customer that this is a one time replacement. Please stress to the customer the vital importance of keeping the wheels clean if they are operating the vehicle in an area that applies calcium chloride or other dust controlling chemicals! "GM of Canada" dealers require prior approval by the District Manager - Customer Care and Service Process (DM-CCSP). "Stardust" Corrosion of Chrome Wheels Figure 3 A third type of finish disturbance results from prolonged exposure to brake dust and resultant penetration of brake dust through the chrome. As brakes are applied hot particles of brake material are thrown off and tend to be forced through the leading edge of the wheel spoke windows by airflow. These Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins: > 00-03-10-002F > Apr > 11 > Wheels - Chrome Wheel Staining/Pitting/Corrosion > Page 13515 hot particles embed themselves in the chrome layer and create a small pit. If the material is allowed to sit on the wheel while it is exposed to moisture or salt, it will corrode the wheel beneath the chrome leaving a pit or small blister in the chrome. Heavy brake dust build-up should be removed from wheels by using GM Chrome Cleaner and Polish, P/N 1050173 (in Canada use 10953013). For moderate cleaning, light brake dust build-up or water spots use GM Swirl Remover Polish, P/N 12377965 (in Canada, use Meguiars Plast-X(TM) Clear Plastic Cleaner and Polish #G12310C**). After cleaning, the wheel should be waxed using GM Cleaner Wax, P/N 12377966 (in Canada, use Meguiars Cleaner Wax #M0616C**), which will help protect the wheel from brake dust and reduce adhesion of any brake dust that gets on the wheel surface. For general maintenance cleaning, PEEK Metal Polish† may be used. It will clean and shine the chrome and leave behind a wax coating that may help protect the finish. Warranty of Stardust Corroded Chrome Wheels Wheels returned with pitting or spotting as a result of neglect and brake dust build-up may be replaced one time. Important Notify the customer that this is a one time replacement. Please stress to the customer the vital importance of keeping the wheels clean and free of prolonged exposure to brake dust build-up. "GM of Canada" dealers require prior approval by the District Manager - Customer Care and Service Process (DM-CCSP). Customer Assistance and Instructions GM has looked for ways customers may improve the appearance of wheels damaged by acidic cleaners. The following product and procedure has been found to dramatically improve the appearance of stained wheels. For wheels that have milky stains caused by acidic cleaners try the following: Notice THE 3M CHROME AND METAL POLISH REQUIRED FOR THIS PROCEDURE IS AN EXTREMELY AGGRESSIVE POLISH/CLEANER. THE WHEELS MUST BE CLEANED BEFORE APPLICATION TO AVOID SCRATCHING THE WHEEL SURFACE. THIS PRODUCT WILL REDUCE THE THICKNESS OF THE CHROME PLATING ON THE WHEEL AND IF USED INCORRECTLY OR EXCESSIVELY MAY REMOVE THE CHROME PLATING ALL TOGETHER, EXPOSING A LESS BRIGHT AND BRASSY COLORED SUB-LAYER. FOLLOW INSTRUCTIONS EXACTLY. 1. Wash the wheels with vigorously with soap and water. This step will clean and may reduce wheel staining. Flood all areas of the wheel with water to rinse. 2. Dry the wheels completely. Notice Begin with a small section of the wheel and with light pressure buff off polish and examine results. ONLY apply and rub with sufficient force and time to remove enough staining that you are satisfied with the results. Some wheels may be stained to the extent that you may only achieve a 50% improvement while others may be able to be restored to the original lustre. IN ALL CASES, only apply until the results are satisfactory. 3. Apply 3M Chrome and Metal Polish #39527* with a clean terry cloth towel. As you apply the polish, the staining will be diminished. 4. When dry, buff off the polish with a clean portion of the towel. 5. Repeat application of the 3M Chrome and Metal Polish until satisfied with the results. If continued applications fail to improve the appearance further discontinue use. This procedure will improve the appearance of the wheels and may, with repeated applications, restore the finish dramatically. For wheels that exhibit spotting from road chemicals the above procedure may marginally improve the condition but will not restore the finish or remove the pitting. In this type of staining the wheel finish has actually been removed in spots and no manner of cleaning will restore the finish. †*We believe this source and their products to be reliable.

Please discard Corporate Bulletin Number 99-08-51-007D (Section 08 - Body and Accessories). This bulletin updates General Motor's position on refinishing aluminum wheels. GM does not endorse any repairs that involve welding, bending, straightening or re-machining. Only cosmetic refinishing of the wheel's coatings, using recommended procedures, is allowed. Evaluating Damage In evaluating damage, it is the GM Dealer's responsibility to inspect the wheel for corrosion, scrapes, gouges, etc. The Dealer must insure that such damage is not deeper than what can be sanded or polished off. The wheel must be inspected for cracks. If cracks are found, discard the wheel. Any wheels with bent rim flanges must not be repaired or refinished. Wheels that have been refinished by an outside company must be returned to the same vehicle. The Dealer must record the wheel ID stamp or the cast date on the wheel in order to assure this requirement. Refer to Refinisher's Responsibility - Outside Company later in this bulletin. Aluminum Wheel Refinishing Recommendations - Chrome-plated aluminum wheels Re-plating these wheels is not recommended. - Polished aluminum wheels These wheels have a polyester or acrylic clearcoat on them. If the clearcoat is damaged, refinishing is possible. However, the required refinishing process cannot be performed in the dealer environment. Refer to Refinisher's Responsibility - Outside Company later in this bulletin. - Painted aluminum wheels These wheels are painted using a primer, color coat, and clearcoat procedure. If the paint is damaged, refinishing is possible. As with polished wheels, all original coatings must be removed first. Media blasting is recommended. Refer to GM Aluminum Refinishing Bulletin #53-17-03A for the re-painting of this type of wheel. - Bright, machined aluminum wheels These wheels have a polyester or acrylic clearcoat on them. In some cases, the recessed "pocket" areas of the wheel may be painted. Surface refinishing is possible. The wheel must be totally stripped by media blasting or other suitable means. The wheel should be resurfaced by using a sanding process rather than a machining process. This allows the least amount of material to be removed. Important Do not use any re-machining process that removes aluminum. This could affect the dimensions and function of the wheel. Painting is an option to re-clearcoating polished and bright machined aluminum wheels. Paint will better mask any surface imperfections and is somewhat more durable than clearcoat alone. GM recommends using Corsican SILVER WAEQ9283 for a fine "aluminum-like" look or Sparkle SILVER WA9967 for a very bright look. As an option, the body color may also be used. When using any of the painting options, it is recommended that all four wheels be refinished in order to maintain color uniformity. Refer to GM Aluminum Refinishing Bulletin #53-17-03A for specific procedures and product recommendations. Refinisher's Responsibility - Outside Company Important Some outside companies are offering wheel refinishing services. Such refinished wheels will be permanently marked by the refinisher and are warranted by the refinisher. Any process that re-machines or otherwise re-manufactures the wheel should not be used. A refinisher's responsibility includes inspecting for cracks using the Zyglo system or the equivalent. Any cracked wheels must not be refinished. No welding, hammering or reforming of any kind is allowed. The wheel ID must be recorded and follow the wheel throughout the process in order to assure that the same wheel is returned. A plastic media blast may be used for clean up of the wheel. Hand and/or lathe sanding of the machined surface and the wheel window is allowed. Material removal, though, must be kept to a minimum. Re-machining of the wheel is not allowed. Paint and/or clear coat must not be present on the following surfaces: the nut chamfers, the wheel mounting surfaces and the wheel pilot hole. The refinisher must permanently ID stamp the wheel and warrant the painted/clearcoated surfaces for a minimum of one year or the remainder of the new vehicle warranty, whichever is Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins: > 99-08-51-007E > Mar > 11 > Wheels/Tires - Refinishing Aluminum Wheels > Page 13521 longer. Important Whenever a wheel is refinished, the mounting surface and the wheel nut contact surfaces must not be painted or clearcoated. Coating these surfaces could affect the wheel nut torque. When re-mounting a tire on an aluminum wheel, coated balance weights must be used in order to reduce the chance of future cosmetic damage.

This bulletin is intended to quickly review and reinforce simple but vital procedures to reduce the possibility of achieving low torque during wheel installation. Always refer to SI for wheel lug nut torque specifications and complete jacking instructions for safe wheel changing. Supercede: This bulletin is being revised to include the 2011 model year and update the available special tool list. Please discard Corporate Bulletin Number 06-03-10-010 (Section 03 Suspension). Frequency of Wheel Changes - Marketplace Driven Just a few years ago, the increasing longevity of tires along with greater resistance to punctures had greatly reduced the number of times wheels were removed to basically required tire rotation intervals. Today with the booming business in accessory wheels/special application tires (such as winter tires), consumers are having tire/wheel assemblies removed - replaced - or installed more than ever. With this increased activity, it opens up more of a chance for error on the part of the technician. This bulletin will review a few of the common concerns and mistakes to make yourself aware of. Proper Servicing Starts With the Right Tools The following tools have been made available to assist in proper wheel and tire removal and installation. - J 41013 Rotor Resurfacing Kit (or equivalent) - J 42450-A Wheel Hub Resurfacing Kit (or equivalent) Corroded Surfaces One area of concern is corrosion on the mating surfaces of the wheel to the hub on the vehicle. Excessive corrosion, dirt, rust or debris built up on these surfaces can mimic a properly tightened wheel in the service stall. Once the vehicle is driven, the debris may loosen, grind up or be washed away from water splash. This action may result in clearance at the mating surface of the wheel and an under-torqued condition. Caution Before installing a wheel, remove any buildup on the wheel mounting surface and brake drum or brake disc mounting surface. Installing wheels with poor metal-to-metal contact at the mounting surfaces can cause wheel nuts to loosen. This may cause a wheel to come off when the vehicle is moving, possibly resulting in a loss of control or personal injury. Whenever you remove the tire/wheel assemblies, you must inspect the mating surfaces. If corrosion is found, you should remove the debris with a die grinder equipped with a fine sanding pad, wire brush or cleaning disc. Just remove enough material to assure a clean, smooth mating surface. The J 41013 (or equivalent) can be used to clean the following surfaces: - The hub mounting surface - The brake rotor mounting surface - The wheel mounting surface Use the J 42450-A (or equivalent) to clean around the base of the studs and the hub. Lubricants, Grease and Fluids Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins: > 06-03-10-010A > Jun > 10 > Wheels - Changing Procedures/Precautions > Page 13526 Some customers may use penetrating oils, grease or other lubricants on wheel studs to aid in removal or installation. Always use a suitable cleaner/solvent to remove these lubricants prior to installing the wheel and tire assemblies. Lubricants left on the wheel studs may cause improper readings of wheel nut torque. Always install wheels to clean, dry wheel studs ONLY. Notice Lubricants left on the wheel studs or vertical mounting surfaces between the wheel and the rotor or drum may cause the wheel to work itself loose after the vehicle is driven. Always install wheels to clean, dry wheel studs and surfaces ONLY. Beginning with 2011 model year vehicles, put a light coating of grease, GM P/N 1051344 (in Canada, P/N 9930370), on the inner surface of the wheel pilot hole to prevent wheel seizure to the axle or bearing hub. Wheel Stud and Lug Nut Damage Always inspect the wheel studs and lug nuts for signs of damage from crossthreading or abuse. You should never have to force wheel nuts down the stud. Lug nuts that are damaged may not retain properly, yet give the impression of fully tightening. Always inspect and replace any component suspected of damage. Tip Always start wheel nuts by hand! Be certain that all wheel nut threads have been engaged BEFORE tightening the nut. Important If the vehicle has directional tread tires, verify the directional arrow on the outboard side of the tire is pointing in the direction of forward rotation. Wheel Nut Tightening and Torque Improper wheel nut tightening can lead to brake pulsation and rotor damage. In order to avoid additional brake repairs, evenly tighten the wheel nuts to the proper torque specification as shown for each vehicle in SI. Always observe the proper wheel nut tightening sequence as shown below in order to avoid trapping the wheel on the wheel stud threads or clamping the wheel slightly off center resulting in vibration. The Most Important Service You Provide While the above information is well known, and wheel removal so common, technicians run the risk of becoming complacent on this very important Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins: > 06-03-10-010A > Jun > 10 > Wheels - Changing Procedures/Precautions > Page 13527 service operation. A simple distraction or time constraint that rushes the job may result in personal injury if the greatest of care is not exercised. Make it a habit to double check your work and to always side with caution when installing wheels.

Please discard Corporate Bulletin Number 00-03-10-006E (Section 03 - Suspension). Important - Before measuring tires on equipment such as the Hunter GSP9700, the vehicle MUST be driven a minimum of 16 km (10 mi) to ensure removal of any flat-spotting. Refer to Corporate Bulletin Number 03-03-10-007E - Tire/Wheel Characteristics of GM Original Equipment Tires. - Equipment such as the Hunter GSP9700 MUST be calibrated prior to measuring tire/wheel assemblies for each vehicle. The purpose of this bulletin is to provide guidance to GM dealers when using tire force variation measurement equipment, such as the Hunter GSP9700. This type of equipment can be a valuable tool in diagnosing vehicle ride concerns. The most common ride concern involving tire radial force variation is highway speed shake on smooth roads. Tire related smooth road highway speed shake can be caused by three conditions: imbalance, out of round and tire force variation. These three conditions are not necessarily related. All three conditions must be addressed. Imbalance is normally addressed first, because it is the simpler of the three to correct. Off-vehicle, two plane dynamic wheel balancers are readily available and can accurately correct any imbalance. Balancer calibration and maintenance, proper attachment of the wheel to the balancer, and proper balance weights, are all factors required for a quality balance. However, a perfectly balanced tire/wheel assembly can still be "oval shaped" and cause a vibration. Before balancing, perform the following procedures. Tire and Wheel Diagnosis 1. Set the tire pressure to the placard values. 2. With the vehicle raised, ensure the wheels are centered on the hub by loosening all wheel nuts and hand-tightening all nuts first by hand while shaking the wheel, then torque to specifications using a torque wrench, NOT a torque stick. 3. Visually inspect the tires and the wheels. Inspect for evidence of the following conditions and correct as necessary: - Missing balance weights - Bent rim flange - Irregular tire wear - Incomplete bead seating - Tire irregularities (including pressure settings) - Mud/ice build-up in wheel - Stones in the tire tread - Remove any aftermarket wheels and/or tires and restore vehicle to original condition prior to diagnosing a smooth road shake condition. 4. Road test the vehicle using the Electronic Vibration Analyzer (EVA) essential tool. Drive for a sufficient distance on a known, smooth road surface to duplicate the condition. Determine if the vehicle is sensitive to brake apply. If the brakes are applied lightly and the pulsation felt in the steering wheel increases, refer to the Brakes section of the service manual that deals with brake-induced pulsation. If you can start to hear the vibration as a low boom noise (in addition to feeling it), but cannot see it, the vehicle likely has a first order (one pulse per propshaft revolution) driveline vibration. Driveline first order vibrations are high enough in frequency that most humans can start to hear them at highway speeds, but are too high to be able to be easily seen. These issues can be caused by driveline imbalance or misalignment. If the vehicle exhibits this low boom and the booming pulses in-and-out on a regular basis (like a throbbing), chances are good that the vehicle could have driveline vibration. This type Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins: > 00-03-10-006F > May > 10 > Wheels/Tires - Tire Radial Force Variation (RFV) > Page 13532 of vibration is normally felt more in the "seat of the pants" than the steering wheel. 5. Next, record the Hertz (Hz) reading as displayed by the EVA onto the tire data worksheet found at the end of this bulletin. This should be done after a tire break-in period of at least 16 km (10 mi) at 72 km/h (45 mph) or greater, in order to eliminate any possible tire flat-spotting. This reading confirms what the vehicle vibration frequency is prior to vehicle service and documents the amount of improvement occurring as the result of the various steps taken to repair. Completing the Steering Wheel Shake Worksheet below is required. A copy of the completed worksheet must be saved with the R.O. and a copy included with any parts returned to the Warranty Parts Center for analysis. A reading of 35 to 50 Hz typically indicates a first order propshaft vibration. If this is the situation, refer to Corporate Bulletin Number 08-07-30-044D. Generally, a reading between 10 and 20 Hz indicates a tire/wheel vibration and if this is the reading obtained, continue using this bulletin. If the tire 1st order vibration goes away and stays away during this evaluation, the cause is likely tire flat-spotting. Tire flat-spotting vibration may come and go at any speed over 72 km/h (45 mph) during the first 10 minutes of operation, if vibration continues after 10 minutes of driving at speeds greater than 72 km/h (45 mph), tire flat-spotting can be ruled out as the cause for vibration. 6. If flat-spotting is the cause, provide the explanation that this has occurred due to the vehicle being parked for long periods of time and that the nature of the tire is to take a set. Refer to Corporate Bulletin Number 03-03-10-007E: Information on Tire/Wheel Characteristics (Vibration, Balance, Shake, Flat Spotting) of GM Original Equipment Tires. 7. If the road test indicates a shake/vibration exists, check the imbalance of each tire/wheel assembly on a known, calibrated, off-car dynamic balancer.Make sure the mounting surface of the wheel and the surface of the balancer are absolutely clean and free of debris. Be sure to chose the proper cone/collet for the wheel, and always use the pilot bore for centering. Never center the wheel using the hub-cap bore since it is not a precision machined surface. If any assembly calls for more than 1/4 ounce on either rim flange, remove all balance weights and rebalance to as close to zero as possible. If you can see the vibration (along with feeling it) in the steering wheel (driving straight without your hands on the wheel), it is very likely to be a tire/wheel first order (one pulse per revolution) disturbance. First order disturbances can be caused by imbalance as well as non-uniformities in tires, wheels or hubs. This first order frequency is too low for a human to hear, but if the amplitude is high enough, it can be seen. If a vibration or shake still exists after balancing, any out of round conditions, of the wheel, and force variation conditions of the tire, must be addressed. Equipment such as the Hunter GSP9700 can address both (it is also a wheel balancer). Tire radial force vibration (RFV) can be defined as the amount of stiffness variation the tire will produce in one revolution under a constant load. Radial force variation is what the vehicle feels because the load (weight) of the vehicle is always on the tires. Although free runout of tires (not under load) is not always a good indicator of a smooth ride, it is critical that total tire/wheel assembly runout be within specification. Equipment such as the Hunter GSP9700 loads the tire, similar to on the vehicle, and measures radial force variation of the tire/wheel assembly. Note that the wheel is affecting the tire's RFV measurement at this point. To isolate the wheel, its runout must be measured. This can be easily done on the Hunter, without the need to set up dial indicators. If the wheel meets the runout specification, the tire's RFV can then be addressed. After measuring the tire/wheel assembly under load, and the wheel alone, the machine then calculates (predicts) the radial force variation of the tire. However, because this is a prediction that can include mounting inaccuracies, and the load wheel is much smaller in diameter than used in tire production, this type of service equipment should NOT be used to audit new tires. Rather, it should be used as a service diagnostic tool to minimize radial force variation of the tire/wheel assembly. Equipment such as the Hunter GSP9700 does an excellent job of measuring wheel runout, and of finding the low point of the wheel (for runout) and the high point of the tire (for radial force variation). This allows the tire to be matched mounted to the wheel for lowest tire/wheel assembly force variation. The machine will simplify this process into easy steps. The following assembly radial force variation numbers should be used as a guide: When measuring RFV and match mounting tires perform the following steps. Measuring Wheel Runout and Assembly Radial Force Variation Important The completed worksheet at the end of this bulletin must be attached to the hard copy of the repair order. - Measure radial force variation and radial runout. - If a road force/balancing machine is used, record the radial force variation (RFV) on the worksheet at the end of this bulletin. It may be of benefit to have the lowest RFV assembly to the front left corner. If the machine is not available and the EVA data suggests there is an issue, swap the tire and wheel assemblies from the front to the back. Re-check on the EVA and if the problem still exists, test another vehicle to find tires that do not exhibit the same frequency and swap those tires onto the subject vehicle. - If a runout/balancing machine is used, record the radial runout of the tire/wheel assemblies on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies are more than.040 in (1.02 mm), match mount the tire to the wheel to get below.040 in (1.02 mm). For sensitive customers, readings of 0.030 inch (0.76 mm) or less are preferable, it may also be of benefit to have the lowest runout assembly to the front left corner. If the machine is not available and the EVA data suggests there is an issue, swap the tire and wheel assemblies from the front to the back. Re-check on the EVA and if the problem still exists, test another vehicle to find tires that do not exhibit the same frequency and swap those tires Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins: > 00-03-10-006F > May > 10 > Wheels/Tires - Tire Radial Force Variation (RFV) > Page 13533 onto the subject vehicle. - After match mounting, the tire/wheel assembly must be rebalanced. If match mounting tires to in-spec wheels produces assembly values higher than these, tire replacement may be necessary. Replacing tires at lower values will probably mean good tires are being condemned. Because tires can sometimes become temporarily flat-spotted, which will affect force variation, it is important that the vehicle be driven at least 16 km (10 mi) prior to measuring. Tire pressure must also be adjusted to the usage pressure on the vehicle's tire placard prior to measuring. Most GM vehicles will tolerate radial force variation up to these levels. However, some vehicles are more sensitive, and may require lower levels. Also, there are other tire parameters that equipment such as the Hunter GSP9700 cannot measure that may be a factor. In such cases, TAC should be contacted for further instructions. Important - When mounting a GM wheel to a wheel balancer/force variation machine, always use the wheel's center pilot hole. This is the primary centering mechanism on all GM wheels; the bolt holes are secondary. Usually a back cone method to the machine should be used. For added accuracy and repeatability, a flange plate should be used to clamp the wheel onto the cone and machine. This system is offered by all balancer manufacturers in GM's dealer program. - Any type of service equipment that removes tread rubber by grinding, buffing or truing is NOT recommended, and may void the tire warranty. However, tires may have been ground by the tire company as part of their tire manufacturing process. This is a legitimate procedure.

Please discard Corporate Bulletin Number 08-03-10-006B (Section 03 - Suspension). Condition Some customers may comment on a tire that slowly loses air pressure over a period of days or weeks. Cause Abrasive elements in the environment may intrude between the tire and wheel at the bead seat. There is always some relative motion between the tire and wheel (when the vehicle is driven) and this motion may cause the abrasive particles to wear the wheel and tire materials. As the wear continues, there may also be intrusion at the tire/wheel interface by corrosive media from the environment. Eventually a path for air develops and a 'slow' leak may ensue. This corrosion may appear on the inboard or outboard bead seating surface of the wheel. This corrosion will not be visible until the tire is dismounted from the wheel. Notice This bulletin specifically addresses issues related to wheel bead seat corrosion that may result in an air leak. For issues related to porosity of the wheel casting that may result in an air leak, please refer to Corporate Bulletin Number 05-03-10-006F - Low Tire Pressure, Leaking Cast Aluminum Wheels (Repair with Adhesive Sealant) Correction In most cases, this type of air loss can be corrected by following the procedure below. Important DO NOT replace a wheel for slow air loss unless you have evaluated and/or tried to repair the wheel with the procedure below. Notice The repair is no longer advised or applicable for chromed aluminum wheels. 1. Remove the wheel and tire assembly for diagnosis. Refer to Tire and Wheel Removal and Installation in SI. 2. After a water dunk tank leak test, if you determine the source of the air leak to be around the bead seat of the wheel, dismount the tire to examine the bead seat. Shown below is a typical area of bead seat corrosion.Typical Location of Bead Seat Corrosion Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > All Technical Service Bulletins: > 08-03-10-006C > Apr > 10 > Tires/Wheels - Tire Slowly Goes Flat/Warning Light ON > Page 13544 Important Other forms of slow air leaks are possible. If the body of the tire, valve stem and wheel flange show no signs of air seepage, refer to Corporate Bulletin Number 05-03-10-003D for additional information on possible wheel porosity issues. 3. Bead seat corrosion is identified by what appears like blistering of the wheel finish, causing a rough or uneven surface that is difficult for the tire to maintain a proper seal on. Below is a close-up photo of bead seat corrosion on an aluminum wheel that was sufficient to cause slow air loss. Close-Up of Bead Seat Corrosion 4. If corrosion is found on the wheel bead seat, measure the affected area as shown below. - For vehicles with 32,186 km (20,000 mi) or less, the total allowable combined linear area of repairable corrosion is 100 mm (4 in) or less. If the total area(s) of corrosion exceed these dimensions, the wheel should be replaced. - For vehicles that have exceeded 32,186 km (20,000 mi), the total allowable combined linear area of repairable corrosion is 200 mm (8 in) or less. If the total area(s) of corrosion exceed these dimensions, the wheel should be replaced. 5. In order to correct the wheel leak, use a clean-up (fine cut) sanding disc or biscuit to remove the corrosion and any flaking paint. You should remove the corrosion back far enough until you reach material that is stable and firmly bonded to the wheel. Try to taper the edge of any flaking paint as best you can in order to avoid sharp edges that may increase the chance of a leak reoccurring. The photo below shows an acceptable repaired surface. Notice Corrosion that extends up the lip of the wheel, where after the clean-up process it would be visible with the tire mounted, is only acceptable on the inboard flange. The inboard flange is not visible with the wheel assembly in the mounted position. If any loose coatings or corrosion extend to the visible surfaces on the FACE of the wheel, that wheel must be replaced. Important Remove ONLY the material required to eliminate the corrosion from the bead seating surface. DO NOT remove excessive amounts of material. ALWAYS keep the sealing surface as smooth and level as possible.

Once the corrosion has been eliminated, you should coat the repaired area with a commercially available tire sealant such as Patch Brand Bead Sealant or equivalent. Commercially available bead sealants are black rubber-like coatings that will permanently fill and seal the resurfaced bead seat. At 21°C (70°F) ambient temperature, this sealant will set-up sufficiently for tire mounting in about 10 minutes.Coated and Sealed Bead Seat 7. Remount the tire and install the repaired wheel and tire assembly. Refer to Tire and Wheel Removal and Installation in SI. Parts Information Patch Brand Bead Sealer is available from Myers Tires at 1-800-998-9897 or on the web at www.myerstiresupply.com. The one-quart size can of sealer will repair about 20 wheels.

Please discard Corporate Bulletin Number 04-03-10-012A (Section 03 - Suspension). Analysis of Returned Wheels Chrome wheels returned under the New Vehicle Limited Warranty for pitting concerns have recently been evaluated. This condition is usually most severe in the vent (or window) area of the front wheels. This "pitting" may actually be brake dust that has been allowed to accumulate on the wheel. The longer this accumulation builds up, the more difficult it is to remove. Cleaning the Wheels In all cases, the returned wheels could be cleaned to their original condition using GM Vehicle Care Cleaner Wax, P/N 12377966 (in Canada, P/N 10952905). When using this product, you should confine your treatment to the areas of the wheel that show evidence of the brake dust build-up. This product is only for use on chromed steel or chromed aluminum wheels. Parts Information Warranty Information Wheel replacement for this condition is NOT applicable under the terms of the New Vehicle Limited Warranty.

Some may describe the noise as sounding like a lifter tick. Cause The finish on the exhaust valve stem(s) may have caused excessive wear on the exhaust valve guide(s) in the cylinder heads. When this occurs, the exhaust valve stem to guide clearance becomes out of specification and the tick noise is created each time the valve stem comes in contact with the guide. Correction 1. Verify that the engine oil level is within the operating range. 2. Verify that the noise in question is not the normal ticking type sound produced by the fuel injectors. 3. Connect a mechanical oil pressure gauge and verify that the engine has adequate oil pressure. Refer to SI for additional information if necessary. 4. If the oil pressure is within specification, then remove the left (front) rocker cover and gasket. Refer to the Valve Rocker Arm Cover Replacement - Left Side in SI. 5. Place shop towels over the rocker arms and push rods to contain engine oil in the next step. 6. Start the engine and allow to idle. Important: The following steps only need to be done on the exhaust valves. 7. Using a block of wood or the wooden handle on a hammer, place a side load on cylinder number 2 exhaust valve spring. ^ If the noise is reduced or eliminated, then there is excessive clearance between that exhaust valve stem and the guide in the cylinder head. Proceed to Step 8. ^ If the noise is NOT reduced or eliminated, then proceed to cylinder number 4 and 6 exhaust valve springs and apply the same type of side load. If the noise is reduced or eliminated then there is excessive clearance between an exhaust valve stem and guide in the cylinder head. Proceed to the next step. 8. Remove the right (rear) rocker cover. Important: It may not be possible to apply a side load to the exhaust springs with a piece of wood or hammer handle because there is less clearance at the rear side of the engine. As a result, the inspection procedure on the rear side is different than the left (front) side. 9. Remove the rocker arm and push rod from cylinder # 1 exhaust valve. Important: With one rocker arm and push rod removed at a time in the next steps the engine will exhibit a noticeable misfire or rough idle during the test. 10. With shop towels in place to contain any oil, start the engine and allow to idle.

Please discard Corporate Bulletin Number 99-01-39-004B (Section 01 - HVAC). Condition Some customers may comment about musty odors emitted from the Heating, Ventilation and Air Conditioning (HVAC) system at vehicle start-up in hot, humid conditions. Cause This condition may be caused by condensate build-up on the evaporator core, which does not evaporate by itself in high humidity conditions. The odor may be the result of microbial growth on the evaporator core. When the blower motor fan is turned on, the microbial growth may release an unpleasant musty odor into the passenger compartment. There are several other possible sources of a musty odor in a vehicle. A common source is a water leak into the interior of the vehicle or foreign material in the HVAC air distribution system. Follow the procedures in SI for identifying and correcting water leaks and air inlet inspection. The procedure contained in this bulletin is only applicable if the odor source has been determined to be microbial growth on the evaporator core inside the HVAC module. Correction Many vehicles currently incorporate an afterblow function within the HVAC control module software. The afterblow feature, when enabled, employs the HVAC blower fan to dry the evaporator after vehicle shut down and this function will inhibit microbial growth. Technicians are to confirm that the customer concern is evaporator core odor and that the vehicle has the imbedded afterblow feature, as defined in the SI document for that specific vehicle model, model year and specific HVAC option. Refer to SI for enabling the afterblow function. Vehicles being delivered in areas prone to high humidity conditions may benefit from having the afterblow enabled calibration installed prior to any customer comment. Important If the vehicle is not factory equipped with the imbedded afterblow enable feature, it may be added with the Electronic Evaporator Dryer Module Kit (P/N 12497910 or AC Delco 15-5876). Important When installing the Electronic Evaporator Dryer Module, you MUST use the included electrical splice connectors to ensure a proper splice. Complete detailed installation instructions and self testing procedures are supplied with the kit. If necessary, the Electronic Evaporator Dryer Module may be installed underhood if it is protected from extreme heat and water splash areas. To immediately remove the evaporator core odor on all suspect vehicles, it is necessary to eliminate the microbial growth and prevent its re-occurrence. To accomplish this, perform the following procedure: Vehicle and Applicator Tool Preparation 1. The evaporator core must be dry. This may be accomplished by disabling the compressor and running the blower fan on the recirc heat setting for an extended period of time. Note Compressor engagement will cause the evaporator core to remain wet and will prevent full adherence of the Coiling Coil Coating to the evaporator core surfaces. 2. Verify that the air conditioning drain hose is not clogged and place a drain pan beneath the vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Heating and Air Conditioning > Evaporator Core > Component Information > Technical Service Bulletins > Customer Interest for Evaporator Core: > 99-01-39-004C > Jun > 09 > A/C - Musty Odors Emitted From (HVAC) System > Page 13717 3. Place a protective cover over the carpet below the evaporator core. 4. Remove the cabin air filter, if equipped, and cover the opening prior to applying the Cooling Coil Coating, as the product may clog the filter. If the cabin air filter appears to have little or no remaining life, suggest a replacement to your customer. 5. If the HVAC module has a blower motor cooling tube, be careful NOT TO SPRAY THE COOLING COIL COATING INTO THE BLOWER MOTOR COOLING TUBE. 6. Attach the Flexible Applicator Pressure Spray Tool (J-43810-20A) to a compressed air line operating at 586 kPa (85 psi) to 793 kPa (115 psi). 7. Shake the bottle of Cooling Coil Coating well. Screw the bottle onto the cap on the applicator tool's pick-up tube. Note The pick-up tube is designed for 120 ml (4 oz) and 240 ml (8 oz) bottles and should coil slightly in the bottom of a 120 ml (4 oz) bottle. 8. Use one of the following three methods to apply the Cooling Coil Coating. Important If the Pressure Applicator Spray Tool (J-43810-20A) is not available, the Cooling Coil Coating is also available in an aerosol can (P/N 12377951 (in Canada, 10953503)). Application Through Blower Motor Control Module Opening - Remove the blower motor control module (blower motor resistor). Refer to the applicable procedure in SI. - Clean any debris or foreign material from inside the HVAC module and on the evaporator core surface. - Apply the Cooling Coil Coating directly to the evaporator core through the blower motor blower motor control module (blower motor resistor) opening. - Use the flexible wand to direct the Cooling Coil Coating over the entire evaporator core and surrounding gasket surfaces. - When the application is complete, install the blower motor blower motor control module (blower motor control module). Application Through Blower Motor Opening - Remove the blower motor. Refer to the applicable blower motor removal procedure in SI. - Clean any debris or foreign material from inside the HVAC module and on the evaporator core surface. - Apply the Cooling Coil Coating directly to the evaporator core through the blower motor opening. - Use the flexible wand to direct the Cooling Coil Coating over the entire evaporator core and surrounding gasket surfaces. - When the application is complete, install the blower motor. Application Through a Hole in the HVAC Module - If neither of the two previous application methods are available, it may be necessary to drill a hole in the HVAC module. - Locate an area of the HVAC module between the blower motor and the evaporator core. Drill a 10 mm (3/8 in) hole in the HVAC module. Use caution to keep the drill clear of the evaporator core and the blower motor fan. - With the air distribution vents closed and the blower motor fan speed on HIGH, insert the applicator tool into the hole and spray the Cooling Coil Coating into the airstream toward the evaporator core. - Use a GM approved RTV sealant to plug the hole in the HVAC module. 9. After the Cooling Coil Coating application is complete, start and run the vehicle for approximately 10 minutes, with the compressor disabled, HVAC mode set to Recirculate/Max, heat set to full warm, blower motor fan speed on high, and one window open approximately 12 mm (1/2 in). This cures the Cooling Coil Coating onto the evaporator core surface. 10. While the engine is running, rinse the applicator tool with warm water to prolong the life of the tool. Be sure to spray warm water through the nozzle to rinse out any residual Cooling Coil Coating still in the capillary pick up tube, otherwise it will dry and clog the applicator tool. Also remove the small green valve from the bottle cap and rinse it thoroughly while rolling it between two fingers and then reinstall it. If this valve is clogged , the Cooling Coil Coating will not flow through the applicator tool. 11. Shut off the engine and enable the compressor again. 12. Verify proper HVAC system operation. 13. Remove the protective cover from inside the vehicle. 14. Remove the drain pan from underneath the vehicle. 15. Reinstall the cabin air filter if necessary.

Application Through a Hole in the HVAC Module - If neither of the two previous application methods are available, it may be necessary to drill a hole in the HVAC module. - Locate an area of the HVAC module between the blower motor and the evaporator core. Drill a 10 mm (3/8 in) hole in the HVAC module. Use caution to keep the drill clear of the evaporator core and the blower motor fan. - With the air distribution vents closed and the blower motor fan speed on HIGH, insert the applicator tool into the hole and spray the Cooling Coil Coating into the airstream toward the evaporator core. - Use a GM approved RTV sealant to plug the hole in the HVAC module. 9. After the Cooling Coil Coating application is complete, start and run the vehicle for approximately 10 minutes, with the compressor disabled, HVAC mode set to Recirculate/Max, heat set to full warm, blower motor fan speed on high, and one window open approximately 12 mm (1/2 in). This cures the Cooling Coil Coating onto the evaporator core surface. 10. While the engine is running, rinse the applicator tool with warm water to prolong the life of the tool. Be sure to spray warm water through the nozzle to rinse out any residual Cooling Coil Coating still in the capillary pick up tube, otherwise it will dry and clog the applicator tool. Also remove the small green valve from the bottle cap and rinse it thoroughly while rolling it between two fingers and then reinstall it. If this valve is clogged , the Cooling Coil Coating will not flow through the applicator tool. 11. Shut off the engine and enable the compressor again. 12. Verify proper HVAC system operation. 13. Remove the protective cover from inside the vehicle. 14. Remove the drain pan from underneath the vehicle. 15. Reinstall the cabin air filter if necessary.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Heating and Air Conditioning > Heater Core > Component Information > Technical Service Bulletins > Cooling System, A/C - Aluminum Heater Cores/Radiators Heater Core: Technical Service Bulletins Cooling System, A/C - Aluminum Heater Cores/Radiators INFORMATION Bulletin No.: 05-06-02-001A Date: July 16, 2008 Subject: Information On Aluminum Heater Core and/or Radiator Replacement Models: 2005 and Prior GM Passenger Cars and Light Duty Trucks (including Saturn) 2003-2005 HUMMER H2 Supercede: This bulletin is being revised to update the Warranty Information. Please discard Corporate Bulletin Number 05-06-02-001 (Section 06 - Engine/Propulsion System). Important: 2004-05 Chevrolet Aveo (Pontiac Wave, Canada Only) does not use DEX-COOL(R). Refer to the flushing procedure explained later in this bulletin. The following information should be utilized when servicing aluminum heater core and/or radiators on repeat visits. A replacement may be necessary because erosion, corrosion, or insufficient inhibitor levels may cause damage to the heater core, radiator or water pump. A coolant check should be performed whenever a heater core, radiator, or water pump is replaced. The following procedures/ inspections should be done to verify proper coolant effectiveness. Caution: To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if the radiator cap or surge tank cap is removed while the engine and radiator are still hot. Important: If the vehicle's coolant is low, drained out, or the customer has repeatedly added coolant or water to the system, then the system should be completely flushed using the procedure explained later in this bulletin. Technician Diagnosis ^ Verify coolant concentration. A 50% coolant/water solution ensures proper freeze and corrosion protection. Inhibitor levels cannot be easily measured in the field, but can be indirectly done by the measurement of coolant concentration. This must be done by using a Refractometer J 23688 (Fahrenheit scale) or J 26568 (centigrade scale), or equivalent, coolant tester. The Refractometer uses a minimal amount of coolant that can be taken from the coolant recovery reservoir, radiator or the engine block. Inexpensive gravity float testers (floating balls) will not completely analyze the coolant concentration fully and should not be used. The concentration levels should be between 50% and 65% coolant concentrate. This mixture will have a freeze point protection of -34 degrees Fahrenheit (-37 degrees Celsius). If the concentration is below 50%, the cooling system must be flushed. ^ Inspect the coolant flow restrictor if the vehicle is equipped with one. Refer to Service Information (SI) and/or the appropriate Service Manual for component location and condition for operation. ^ Verify that no electrolysis is present in the cooling system. This electrolysis test can be performed before or after the system has been repaired. Use a digital voltmeter set to 12 volts. Attach one test lead to the negative battery post and insert the other test lead into the radiator coolant, making sure the lead does not touch the filler neck or core. Any voltage reading over 0.3 volts indicates that stray current is finding its way into the coolant. Electrolysis is often an intermittent condition that occurs when a device or accessory that is mounted to the radiator is energized. This type of current could be caused from a poorly grounded cooling fan or some other accessory and can be verified by watching the volt meter and turning on and off various accessories or engage the starter motor. Before using one of the following flush procedures, the coolant recovery reservoir must be removed, drained, cleaned and reinstalled before refilling the system. Notice: ^ Using coolant other than DEX‐COOL(R) may cause premature engine, heater core or radiator corrosion. In addition, the engine coolant may require changing sooner, at 30,000 miles (50,000 km) or 24 months, whichever occurs first. Any repairs would not be covered by your warranty. Always use DEX‐COOL(R) (silicate free) coolant in your vehicle. ^ If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost would not be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Heating and Air Conditioning > Heater Core > Component Information > Technical Service Bulletins > Cooling System, A/C - Aluminum Heater Cores/Radiators > Page 13742 Flushing Procedures using DEX-COOL(R) Important: The following procedure recommends refilling the system with DEX-COOL(R), P/N 12346290 (in Canada, use P/N 10953464), GM specification 6277M. This coolant is orange in color and has a service interval of 5 years or 240,000 km (150,000 mi). However, when used on vehicles built prior to the introduction of DEX-COOL(R), maintenance intervals will remain the same as specified in the Owner's Manual. ^ If available, use the approved cooling system flush and fill machine (available through the GM Dealer Equipment Program) following the manufacturer's operating instructions. ^ If approved cooling system flush and fill machine is not available, drain the coolant and dispose of properly following the draining procedures in the appropriate Service Manual. Refill the system using clear, drinkable water and run the vehicle until the thermostat opens. Repeat and run the vehicle three (3) times to totally remove the old coolant or until the drained coolant is almost clear. Once the system is completely flushed, refill the cooling system to a 50%-60% concentration with DEX‐COOL(R), P/N 12346290 (in Canada, use P/N 10953464), GM specification 6277M, following the refill procedures in the appropriate Service Manual. If a Service Manual is not available, fill half the capacity of the system with 100% DEX-COOL(R), P/N 12346290 (in Canada, use P/N 10953464), GM specification 6277M. Then slowly add clear, drinkable water (preferably distilled) to the system until the level of the coolant mixture has reached the base of the radiator neck. Wait two (2) minutes and reverify the coolant level. If necessary, add clean water to restore the coolant to the appropriate level. Once the system is refilled, reverify the coolant concentration using a Refractometer J 23688 (Fahrenheit scale) or J 26568 (centigrade scale) coolant tester, or equivalent. The concentration levels should be between 50% and 65%. Flushing Procedures using Conventional Silicated (Green Colored) Coolant Important: 2004-2005 Chevrolet Aveo (Pontiac Wave, Canada Only) does not use DEX‐COOL(R). The Aveo and Wave are filled with conventional, silicated engine coolant that is blue in color. Silicated coolants are typically green in color and are required to be drained, flushed and refilled every 30,000 miles (48,000 km). The Aveo and Wave are to be serviced with conventional, silicated coolant. Use P/N 12378560 (1 gal) (in Canada, use P/N 88862159 (1 L). Refer to the Owner's Manual or Service Information (SI) for further information on OEM coolant. Important: Do not mix the OEM orange colored DEX-COOL(R) coolant with green colored coolant when adding coolant to the system or when servicing the vehicle's cooling system. Mixing the orange and green colored coolants will produce a brown coolant which may be a customer dissatisfier and will not extend the service interval to that of DEX-COOL(R). Conventional silicated coolants offered by GM Service and Parts Operations are green in color. ^ If available, use the approved cooling system flush and fill machine (available through the GM Dealer Equipment Program) following the manufacturer's operating instructions. ^ If approved cooling systems flush and fill machine is not available, drain coolant and dispose of properly following the draining procedures in appropriate Service Manual. Refill the system using clear, drinkable water and run vehicle until thermostat opens. Repeat and run vehicle three (3) times to totally remove old coolant or until drained coolant is almost clear. Once the system is completely flushed, refill the cooling system to a 50%-60% concentration with a good quality ethylene glycol base engine coolant, P/N 12378560, 1 gal (in Canada, use P/N 88862159 1 L), conforming to GM specification 1825M, or recycled coolant conforming to GM specification 1825M, following the refill procedures in the appropriate Service Manual. If a Service Manual is not available, fill half the capacity of the system with 100% good quality ethylene glycol base (green colored) engine coolant, P/N 12378560 1 gal., (in Canada, use P/N 88862159 1 L) conforming to GM specification 1825M. Then slowly add clear, drinkable water (preferably distilled) to system until the level of the coolant mixture has reached the base of the radiator neck. Wait two (2) minutes and recheck coolant level. If necessary, add clean water to restore coolant to the appropriate level. Once the system is refilled, recheck the coolant concentration using a Refractometer J 23688 (Fahrenheit scale) or J 26568 (centigrade scale) coolant tester, or equivalent. Concentration levels should be between 50% and 65%.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Heating and Air Conditioning > Refrigerant > Component Information > Technical Service Bulletins > A/C - Refrigerant Recovery/Recycling/Equipment Refrigerant: Technical Service Bulletins A/C - Refrigerant Recovery/Recycling/Equipment Bulletin No.: 08-01-38-001 Date: January 25, 2008 INFORMATION Subject: Information On New GE-48800 CoolTech Refrigerant Recovery/Recharge Equipment Models: 2008 and Prior GM Passenger Cars and Light Duty Trucks (Including Saturn) 2008 and Prior HUMMER H2, H3 2005-2008 Saab 9-7X Attention: This bulletin is being issued to announce the release of GM approved Air Conditioning (A/C) Refrigerant Recovery and Recharging Equipment that meets the new Society of Automotive Engineers (SAE) J2788 Refrigerant Recovery Standards. The ACR2000 (J-43600) cannot be manufactured in its current state after December 2007 and will be superseded by GE-48800. The new J2788 standard does not require that GM Dealers replace their ACR2000 units. ACR2000's currently in use are very capable of servicing today's refrigerant systems when used correctly and can continue to be used. Details regarding the new SAE J2788 standard are outlined in GM Bulletin 07-01-38-004. Effective February 1 2008, new A/C Refrigerant Recovery/Recharging equipment (P/N GE-48800) will be released as a required replacement for the previously essential ACR2000 (J-43600). This equipment is SAE J2788 compliant and meets GM requirements for A/C Refrigerant System Repairs on all General Motors vehicles, including Hybrid systems with Polyolester (POE) refrigerant oil. This equipment will not be shipped as an essential tool to GM Dealerships. In addition, this equipment is Hybrid compliant and designed to prevent oil cross contamination when servicing Hybrid vehicles with Electric A/C Compressors that use POE refrigerant oil. The ACR2000 (J-43600) will need to be retrofitted with a J-43600-50 (Hose - ACR2000 Oil Flush Loop) to be able to perform Hybrid A/C service work. All Hybrid dealers will receive the J-43600-50, with installation instructions, as a component of the Hybrid essential tool package. Dealerships that do not sell Hybrids, but may need to service Hybrids, can obtain J-43600-50 from SPX Kent Moore. Refer to GM Bulletin 08-01-39-001 for the ACR2000 Hose Flush procedure. The High Voltage (HV) electric A/C compressor used on Two Mode Hybrid vehicles uses a Polyolester (POE) refrigerant oil instead of a Polyalkylene Glycol (PAG) synthetic refrigerant oil. This is due to the better electrical resistance of the POE oil and its ability to provide HV isolation. Failure to flush the hoses before adding refrigerant to a Hybrid vehicle with an electric A/C compressor may result in an unacceptable amount of PAG oil entering the refrigerant system. It may cause a Battery Energy Control Module Hybrid Battery Voltage System Isolation Lost Diagnostic Trouble Code (DTC P1AE7) to be set. Additionally, the A/C system warranty will be voided. Warranty Submission Requirements The Electronically Generated Repair Data (snapshot summary) and printer functions have been eliminated from the GE-48800. The VGA display and temperature probes were eliminated to reduce equipment costs. As a result, effective immediately the 18 digit "Snapshot/Charge Summary" code is no longer required for Air Conditioning (A/C) refrigerant system repairs that are submitted for warranty reimbursement. The charge summary data from before and after system repairs will continue to required, but documented on the repair order only. Both high and low pressures and the recovery and charge amounts should be noted during the repair and entered on the repair order. If using ACR2000 (J-43600), the "Snapshot/Charge Summary" printouts should continue to be attached to the shops copy of the repair order. The labor codes that are affected by this requirement are D3000 through D4500.

When involved in an accident resulting in sheet metal damage or driver-side air bag deployment, the steering column must be inspected for both electrical system integrity and steering column collapse. Go to Diagnostic System Check - Vehicle. * If the steering column electrical system integrity is not within specifications, the complete steering column must be replaced. * If the steering column collapse mechanism is not within specifications, but the electrical system integrity is within specifications, then the steering column upper jacket must be replaced. Road test the vehicle when ever any steering system repairs or diagnostics have been performed. Electric Power Steering (EPS) Inspection 1. Install a scan tool. 2. Start the engine. Important: After centering the steering wheel, remove hands and other objects from the steering wheel. Ensure the suspension is relaxed and that no bias, or uneven force is being applied to the steering system. 3. Turn the steering wheel 90 degrees to the left, then 90 degrees to the right, then return the steering wheel to center. 4. Using the scan tool, observe the Torque Sensor Main data parameter in the EPS data list. Correct parameter range for the torque sensor is <+ or 1 N.m (0.7 lb ft). 5. If the value is greater than the specified range then replace the steering column assembly. Collapse Measurement A vehicle involved in an accident resulting in sheet metal damage or drivers-side air bag deployment will require an inspection for steering column collapse. If the steering column collapse measurement is greater than 3 mm than the steering column upper jacket must be replaced. For steering column collapse measurement, use the following procedure: 1. Remove the steering column trim covers.

There are parts of the SIR system installed in various locations around a vehicle. To find the location of the SIR components refer to SIR Identification Views. There are several reasons for disabling the SIR system, such as repairs to the SIR system or servicing a component near or attached to an SIR component. There are several ways to disable the SIR system depending on what type of service is being performed. The following information covers the proper procedures for disabling/enabling the SIR system. SIR Service Precautions Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Failure to observe the correct procedure could cause deployment of the SIR components. Serious injury can occur. Failure to observe the correct procedure could also result in unnecessary SIR system repairs. The inflatable restraint sensing and diagnostic module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the air bags if the SDM loses battery power during a collision. Deployment power is available for as much as 1 minute after disconnecting the vehicle power. Waiting 1 minute before working on the system after disabling the SIR system prevents deployment of the air bags from the reserved energy supply. General Service Instructions The following are general service instructions which must be followed in order to properly repair the vehicle and return it to its original integrity: * Do not expose inflator modules to temperatures above 65°C (150°F). * Verify the correct replacement part number. Do not substitute a component from a different vehicle. * Use only original GM replacement parts available from your authorized GM dealer. Do not use salvaged parts for repairs to the SIR system. Discard any of the following components if it has been dropped from a height of 91 cm (3 feet) or greater: * Inflatable restraint sensing and diagnostic module (SDM) * Any Inflatable restraint air bag module * Inflatable restraint steering wheel module coil * Any Inflatable restraint sensor * Inflatable restraint seat belt pretensioners * Inflatable restraint Passenger Presence System (PPS) module or sensor Disabling Procedure - Air Bag Fuse 1. Turn the steering wheel so that the vehicles wheels are pointing straight ahead. 2. Place the ignition in the OFF position. Important: The SDM may have more than one fused power input. To ensure there is no unwanted SIR deployment, personal injury, or unnecessary SIR system repairs, remove all fuses supplying power to the SDM. With all SDM fuses removed and the ignition switch in the ON position, the AIR BAG warning indicator illuminates. This is normal operation, and does not indicate a SIR system malfunction. 3. Locate and remove the fuse(s) supplying power to the SDM. 4. Wait 1 minute before working on the system. Enabling Procedure - Air Bag Fuse 1. Place the ignition in the OFF position.

In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained, small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. If the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using GM Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may be involved. For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned. -- US dealers - GM DealerWorld Recall Information -- Export dealers - sent directly to dealers The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information No parts are required for this recall. Service Procedure Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration. The Passenger Presence System (PPS) is used to monitor the weight and pattern of an occupant on the front outboard passenger seat and communicate Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Restraint Systems > Air Bag Systems > Seat Occupant Classification Module - Air Bag > Component Information > Technical Service Bulletins > Recalls: > 07174 > Aug > 07 > Recall - Seat Occupant Sensor Calibration Error > Page 13938 the status to the Sensing and Diagnostic module (SDM) whether to enable or suppress the deployment of the passenger airbag. The PPS consists of an electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators. Reprogram the electronic control module (ECU). Refer to the instructions below. Tech 2 Legacy or J2534 Pass-Thru programming method for the PPS Offset Reset (PPS) Important: If Tech 2 Legacy or J2534 Pass-Thru programming fails, call Techline Customer Support Center (TCSC) at 1-800-828-6860 (English) or 1-800-503-3222 (French). A "Candi" module is necessary. Calibration Information Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Center and it will be provided. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: - The RS-232 communication cable port - The connection at the data link connector (DLC) - The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Select PPS Offset Reset from the Supported Controller screen in TIS2Web. Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required. Courtesy Transportation - For US The General Motors Courtesy Transportation Program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product recall is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for courtesy transportation guidelines.

Customer Notification - For US General Motors will notify customers of this recall on their vehicle (see copy of customer letter shown in this bulletin). Customer Notification - For Export Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the sample letter. Dealer Recall Responsibility - For US and Export (US States, Territories, and Possessions) The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time. This bulletin is notice to you that the new motor vehicles included in this recall may not comply with the standard identified above. Under Title 49, Section 30112 of the United States Code, it is illegal for a dealer to sell a new motor vehicle which the dealer knows does not comply with an applicable Federal Motor Vehicle Safety Standard. As a consequence, if you sell any of these motor vehicles without first performing the recall correction, your dealership may be subject to a civil penalty for each such sale. Dealer Recall Responsibility - All All unsold new vehicles in dealers' possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall bulletin before customers take possession of these vehicles. Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter is shown in this bulletin for your use in contacting customers.

In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. In the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided in GMinfoNet Recall Reports. Dealers will not have a report available if they have no involved vehicles currently assigned. The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information No parts are required for this recall. Service Procedure Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration. The Passenger Presence System (PPS) is used to monitor the weight and pattern of an occupant on the front outboard passenger seat and communicate the status to the Sensing and Diagnostic module (SDM) whether to enable or suppress the deployment of the passenger airbag. The PPS consists of an electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators. Reprogram the electronic control module (ECU). Refer to the instructions below.

A "Candi" module is necessary. Calibration Information Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Centre and it will be provided. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use jumper cables from an additional battery. Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: - The RS-232 communication cable port - The connection at the data link connector (DLC) - The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required.

NHTSA CAMPAIGN ID NUMBER: 07V344000 MFR'S REPORT DATE: August 06, 2007 COMPONENT: Air Bags: Frontal: Sensor/Control Module POTENTIAL NUMBER OF UNITS AFFECTED: 437 SUMMARY: Certain sport utility vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 208, "Occupant Crash Protection." In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative unrestrained small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. CONSEQUENCE: Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. This can increase the risk of injury to a seat occupant during certain crash conditions. REMEDY: Dealers will reprogram the seat's electronic control unit. The manufacturer has not yet provided an owner notification schedule for this campaign. Owners may contact Chevrolet at 1-800-630-2438 or Pontiac at 1-800-620-7668. NOTES: GM recall No. 070174.

In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained, small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. If the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using GM Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may be involved. For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned. -- US dealers - GM DealerWorld Recall Information -- Export dealers - sent directly to dealers The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records.

In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. In the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided in GMinfoNet Recall Reports. Dealers will not have a report available if they have no involved vehicles currently assigned. The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information No parts are required for this recall. Service Procedure Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration. The Passenger Presence System (PPS) is used to monitor the weight and pattern of an occupant on the front outboard passenger seat and communicate the status to the Sensing and Diagnostic module (SDM) whether to enable or suppress the deployment of the passenger airbag. The PPS consists of an electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators. Reprogram the electronic control module (ECU). Refer to the instructions below.

A "Candi" module is necessary. Calibration Information Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Centre and it will be provided. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use jumper cables from an additional battery. Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: - The RS-232 communication cable port - The connection at the data link connector (DLC) - The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required.

Please discard Corporate Bulletin Number 06-08-50-009E (Section 08 - Body and Accessories). Concerns About Safety and Alterations to the Front Passenger Seat Important ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE THE SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT AS RELEASED BY GM FOR THAT VEHICLE. DO NOT ALTER THE SEAT COVERS OR SEAT-RELATED EQUIPMENT. ANY ALTERATIONS TO SEAT COVERS OR GM ACCESSORIES DEFEATS THE INTENDED DESIGN OF THE SYSTEM. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ALTERATIONS, INCLUDING ANY WARRANTY REPAIRS INCURRED. The front passenger seat in many GM vehicles is equipped with a passenger sensing system that will turn off the right front passenger's frontal airbag under certain conditions, such as when an infant or child seat is present. In some vehicles, the passenger sensing system will also turn off the right front passenger's seat mounted side impact airbag. For the system to function properly, sensors are used in the seat to detect the presence of a properly-seated occupant. The passenger sensing system may not operate properly if the original seat trim is replaced (1) by non-GM covers, upholstery or trim, or (2) by GM covers, upholstery or trim designed for a different vehicle or (3) by GM covers, upholstery or trim that has been altered by a trim shop, or (4) if any object, such as an aftermarket seat heater or a comfort enhancing pad or device is installed under the seat fabric or between the occupant and the seat fabric. Aftermarket Seat Heaters, Custom Upholstery, and Comfort Enhancing Pads or Devices Important ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE ONLY SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT RELEASED AS GM ACCESSORIES FOR THAT VEHICLE. DO NOT USE ANY OTHER TYPE OF SEAT COVERS OR SEAT-RELATED EQUIPMENT, OR GM ACCESSORIES RELEASED FOR OTHER VEHICLE APPLICATIONS. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ACCESSORIES, INCLUDING ANY WARRANTY REPAIRS MADE NECESSARY BY SUCH USE. Many types of aftermarket accessories are available to customers, upfitting shops, and dealers. Some of these devices sit on top of, or are Velcro(R) strapped to the seat while others such as seat heaters are installed under the seat fabric. Additionally, seat covers made of leather or other materials may have different padding thickness installed that could prevent the Passenger Sensing System from functioning properly. Never alter the vehicle seats. Never add pads or other devices to the seat cushion, as this may interfere with the operation of the Passenger Sensing System and either prevent proper deployment of the passenger airbag or prevent proper suppression of the passenger air bag.

Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required. Courtesy Transportation The General Motors Courtesy Transportation Program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product recall is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for courtesy transportation guidelines.

NHTSA CAMPAIGN ID NUMBER: 07V344000 MFR'S REPORT DATE: August 06, 2007 COMPONENT: Air Bags: Frontal: Sensor/Control Module POTENTIAL NUMBER OF UNITS AFFECTED: 437 SUMMARY: Certain sport utility vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 208, "Occupant Crash Protection." In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative unrestrained small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. CONSEQUENCE: Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. This can increase the risk of injury to a seat occupant during certain crash conditions. REMEDY: Dealers will reprogram the seat's electronic control unit. The manufacturer has not yet provided an owner notification schedule for this campaign. Owners may contact Chevrolet at 1-800-630-2438 or Pontiac at 1-800-620-7668. NOTES: GM recall No. 070174. Customers may also contact The National Highway Traffic Safety Administration's Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to http://www.safercar.gov.

Concerns About Safety and Alterations to the Front Passenger Seat Important ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE THE SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT AS RELEASED BY GM FOR THAT VEHICLE. DO NOT ALTER THE SEAT COVERS OR SEAT-RELATED EQUIPMENT. ANY ALTERATIONS TO SEAT COVERS OR GM ACCESSORIES DEFEATS THE INTENDED DESIGN OF THE SYSTEM. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ALTERATIONS, INCLUDING ANY WARRANTY REPAIRS INCURRED. The front passenger seat in many GM vehicles is equipped with a passenger sensing system that will turn off the right front passenger's frontal airbag under certain conditions, such as when an infant or child seat is present. In some vehicles, the passenger sensing system will also turn off the right front passenger's seat mounted side impact airbag. For the system to function properly, sensors are used in the seat to detect the presence of a properly-seated occupant. The passenger sensing system may not operate properly if the original seat trim is replaced (1) by non-GM covers, upholstery or trim, or (2) by GM covers, upholstery or trim designed for a different vehicle or (3) by GM covers, upholstery or trim that has been altered by a trim shop, or (4) if any object, such as an aftermarket seat heater or a comfort enhancing pad or device is installed under the seat fabric or between the occupant and the seat fabric. Aftermarket Seat Heaters, Custom Upholstery, and Comfort Enhancing Pads or Devices Important ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE ONLY SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT RELEASED AS GM ACCESSORIES FOR THAT VEHICLE. DO NOT USE ANY OTHER TYPE OF SEAT COVERS OR SEAT-RELATED EQUIPMENT, OR GM ACCESSORIES RELEASED FOR OTHER VEHICLE APPLICATIONS. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ACCESSORIES, INCLUDING ANY WARRANTY REPAIRS MADE NECESSARY BY SUCH USE. Many types of aftermarket accessories are available to customers, upfitting shops, and dealers. Some of these devices sit on top of, or are Velcro(R) strapped to the seat while others such as seat heaters are installed under the seat fabric. Additionally, seat covers made of leather or other materials may have different padding thickness installed that could prevent the Passenger Sensing System from functioning properly. Never alter the vehicle seats. Never add pads or other devices to the seat cushion, as this may interfere with the operation of the Passenger Sensing System and either prevent proper deployment of the passenger airbag or prevent proper suppression of the passenger air bag.

The head restraint will not operate to its design intent if the original foam is replaced (1) by non-GM foam or head restraint, (2) by GM foam or head restraint designed for a different vehicle, (3) by GM foam or head restraint that has been altered by a trim shop or (4) if any object, such as an aftermarket comfort enhancing pad or device, is installed. Never modify the design of the head restraint or remove the head restraint from the vehicle as this may interfere with the operation of the seating and restraint systems and may prevent proper positioning of the passenger within the vehicle.

In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained, small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. If the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using GM Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may be involved. For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned. -- US dealers - GM DealerWorld Recall Information -- Export dealers - sent directly to dealers The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information No parts are required for this recall. Service Procedure Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration. The Passenger Presence System (PPS) is used to monitor the weight and pattern of an occupant on the front outboard passenger seat and communicate Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Restraint Systems > Relays and Modules - Restraint Systems > Seat Occupant Classification Module - Air Bag > Component Information > Technical Service Bulletins > Recalls: > 07174 > Aug > 07 > Recall - Seat Occupant Sensor Calibration Error > Page 14151 the status to the Sensing and Diagnostic module (SDM) whether to enable or suppress the deployment of the passenger airbag. The PPS consists of an electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators. Reprogram the electronic control module (ECU). Refer to the instructions below. Tech 2 Legacy or J2534 Pass-Thru programming method for the PPS Offset Reset (PPS) Important: If Tech 2 Legacy or J2534 Pass-Thru programming fails, call Techline Customer Support Center (TCSC) at 1-800-828-6860 (English) or 1-800-503-3222 (French). A "Candi" module is necessary. Calibration Information Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Center and it will be provided. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: - The RS-232 communication cable port - The connection at the data link connector (DLC) - The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Select PPS Offset Reset from the Supported Controller screen in TIS2Web. Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required. Courtesy Transportation - For US The General Motors Courtesy Transportation Program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product recall is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for courtesy transportation guidelines.

Customer Notification - For US General Motors will notify customers of this recall on their vehicle (see copy of customer letter shown in this bulletin). Customer Notification - For Export Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the sample letter. Dealer Recall Responsibility - For US and Export (US States, Territories, and Possessions) The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time. This bulletin is notice to you that the new motor vehicles included in this recall may not comply with the standard identified above. Under Title 49, Section 30112 of the United States Code, it is illegal for a dealer to sell a new motor vehicle which the dealer knows does not comply with an applicable Federal Motor Vehicle Safety Standard. As a consequence, if you sell any of these motor vehicles without first performing the recall correction, your dealership may be subject to a civil penalty for each such sale. Dealer Recall Responsibility - All All unsold new vehicles in dealers' possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall bulletin before customers take possession of these vehicles. Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin.

In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. In the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided in GMinfoNet Recall Reports. Dealers will not have a report available if they have no involved vehicles currently assigned. The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information No parts are required for this recall. Service Procedure Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration. The Passenger Presence System (PPS) is used to monitor the weight and pattern of an occupant on the front outboard passenger seat and communicate the status to the Sensing and Diagnostic module (SDM) whether to enable or suppress the deployment of the passenger airbag. The PPS consists of an electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators. Reprogram the electronic control module (ECU). Refer to the instructions below.

A "Candi" module is necessary. Calibration Information Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Centre and it will be provided. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use jumper cables from an additional battery. Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: - The RS-232 communication cable port - The connection at the data link connector (DLC) - The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required.

NHTSA CAMPAIGN ID NUMBER: 07V344000 MFR'S REPORT DATE: August 06, 2007 COMPONENT: Air Bags: Frontal: Sensor/Control Module POTENTIAL NUMBER OF UNITS AFFECTED: 437 SUMMARY: Certain sport utility vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 208, "Occupant Crash Protection." In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative unrestrained small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. CONSEQUENCE: Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. This can increase the risk of injury to a seat occupant during certain crash conditions. REMEDY: Dealers will reprogram the seat's electronic control unit. The manufacturer has not yet provided an owner notification schedule for this campaign. Owners may contact Chevrolet at 1-800-630-2438 or Pontiac at 1-800-620-7668. NOTES: GM recall No. 070174.

In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained, small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. If the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using GM Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may be involved. For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned. -- US dealers - GM DealerWorld Recall Information -- Export dealers - sent directly to dealers The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries.

There are parts of the SIR system installed in various locations around a vehicle. To find the location of the SIR components refer to SIR Identification Views. There are several reasons for disabling the SIR system, such as repairs to the SIR system or servicing a component near or attached to an SIR component. There are several ways to disable the SIR system depending on what type of service is being performed. The following information covers the proper procedures for disabling/enabling the SIR system. SIR Service Precautions Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Failure to observe the correct procedure could cause deployment of the SIR components. Serious injury can occur. Failure to observe the correct procedure could also result in unnecessary SIR system repairs. The inflatable restraint sensing and diagnostic module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the air bags if the SDM loses battery power during a collision. Deployment power is available for as much as 1 minute after disconnecting the vehicle power. Waiting 1 minute before working on the system after disabling the SIR system prevents deployment of the air bags from the reserved energy supply. General Service Instructions The following are general service instructions which must be followed in order to properly repair the vehicle and return it to its original integrity: * Do not expose inflator modules to temperatures above 65°C (150°F). * Verify the correct replacement part number. Do not substitute a component from a different vehicle. * Use only original GM replacement parts available from your authorized GM dealer. Do not use salvaged parts for repairs to the SIR system. Discard any of the following components if it has been dropped from a height of 91 cm (3 feet) or greater: * Inflatable restraint sensing and diagnostic module (SDM) * Any Inflatable restraint air bag module * Inflatable restraint steering wheel module coil * Any Inflatable restraint sensor * Inflatable restraint seat belt pretensioners * Inflatable restraint Passenger Presence System (PPS) module or sensor Disabling Procedure - Air Bag Fuse 1. Turn the steering wheel so that the vehicles wheels are pointing straight ahead. 2. Place the ignition in the OFF position. Important: The SDM may have more than one fused power input. To ensure there is no unwanted SIR deployment, personal injury, or unnecessary SIR system repairs, remove all fuses supplying power to the SDM. With all SDM fuses removed and the ignition switch in the ON position, the AIR BAG warning indicator illuminates. This is normal operation, and does not indicate a SIR system malfunction. 3. Locate and remove the fuse(s) supplying power to the SDM. 4. Wait 1 minute before working on the system. Enabling Procedure - Air Bag Fuse 1. Place the ignition in the OFF position.

Please discard Corporate Bulletin Number 05-09-40-002D (Section 09 - Restraints). The purpose of this bulletin is to explain when the safety belts are supposed to lock. There are several different locking situations for both front and rear safety belts. Overspool Lock There is an unintentional locking condition that ALL safety belts from ALL manufacturers may experience called "overspool lock". If the webbing snaps back to the stowed position rapidly enough, the retractor will lock with the belt fully stowed. This is more likely to occur when customers "help" the belt to retract. Without the weight of the latch plate and friction to slow the retractive speed of the webbing, the higher than normal webbing retraction speed that occurs engages the locking mechanism when a sudden stop occurs at the end of web travel. Since the webbing is now fully loaded on the spool, the retractor cannot rewind itself further to release the locking mechanism. When this happens, the occupant cannot extract the belt to wear it. DO NOT replace the retractor for this condition until first attempting to disengage the locking mechanism by following the recommendation listed below. Recommendation Pull hard on the locked webbing and then release. The hard pull extracts a small amount of webbing from the retractor which, in turn, permits a small amount of retraction to occur when released. This is all that is needed to disengage the locking mechanism. The safety belt will now function properly. Vehicle Sensing This type of locking occurs in response to the vehicle under the following conditions: - The vehicle changes speed or direction abruptly (the vehicle goes into rapid acceleration OR rapid deceleration or there is aggressive cornering). - It can also occur in a static condition when a vehicle is parked on a large slant (fore-aft or side-to-side), such as streets in San Francisco, California. - It may also occur over rough road conditions where the retractor mechanism is bounced into a locked condition. In all of these conditions, as long as tension is maintained on the webbing, the belt will stay locked. When the tension is released, the belt retracts slightly, the lock bar disengages and the safety belt should return to normal function. Please inform customers that may comment that "the belt locks intermittently" that this is the design intent and the belt is functioning properly. Web Sensing This type of locking occurs in response to the extraction of webbing. When the webbing reels out at an accelerated rate, it goes into lock mode and stays there until tension is again released. To observe this condition, extract the webbing quickly. Customers may refer to this condition as "intermittent lock-up" and encounter it when trying to put the belt on too quickly. Automatic Locking (ALR) When the webbing is pulled all the way out, it automatically converts the retractor into a cinch-down mode (i.e. ALR). This is typically used to tightly secure a child seat to the vehicle. Some customers may experience inadvertent activation of ALR mode if they happen to pull the belt all the way out to the end of travel while they are putting the belt on. The ALR mode of operation is automatically cancelled when the belt is unfastened and stowed (the belt returns to normal sensitive function). Corvette only - This locking mechanism is also provided at the driver's position of the Corvette only, as a unique feature. Corvette customers may find this feature appealing when they plan to operate the vehicle in a "spirited" manner (such as driving in mountainous terrain). With the ALR active, the operator is snugly cinched into the seat and kept firmly in place during high G-force driving maneuvers.

Please discard Corporate Bulletin Number 99-09-40-005E (Section 09 Restraints). Important: DO NOT use belt extenders when securing a child restraint. The seat and shoulder belt restraint systems used in all General Motors vehicles have sufficient belt length to accommodate most drivers and passengers. Consequently, requests for belt extensions (extenders) should be minimal. Seat belt extenders are available ONLY IN BLACK for most GM passenger cars and trucks produced in recent years. They are available in two different lengths, 23 cm (9 in) and 38 cm (15 in). They are designed to be coupled with the existing belts in each vehicle. When in use, the extender makes the belt arrangement a "custom fit" and use by anyone else or in another vehicle will lessen or nullify the protection offered by the vehicle's restraint system. For this reason, it is extremely important that the correct length extender be used for the vehicle and occupant intended. Important: Do not use an extender just to make it easier to buckle the safety belt. Use an extender only when you cannot buckle the safety belt without using an extender. Parts Information For part numbers, usage and availability of extenders, see Extension Kit in Group 14.875 (cars) or Group 16.714 (trucks) of the appropriate parts catalog. Saturn retailers should refer to the appropriate model year Parts & Illustration catalog for the vehicle. U.S. Saab dealers should contact the Parts Help line. Canadian Saab dealers should fax requests to Partech Canada. Warranty Information ^ Seat belt extenders are a NO CHARGE item to all GM customers who request them for their specific vehicles. ^ Dealers should not be charging part costs since these extenders are supplied by GM to the dealers. ^ Dealers should not be charging labor costs since the extender can be customer installed.

Please discard Corporate Bulletin Number 05-09-40-002D (Section 09 - Restraints). The purpose of this bulletin is to explain when the safety belts are supposed to lock. There are several different locking situations for both front and rear safety belts. Overspool Lock There is an unintentional locking condition that ALL safety belts from ALL manufacturers may experience called "overspool lock". If the webbing snaps back to the stowed position rapidly enough, the retractor will lock with the belt fully stowed. This is more likely to occur when customers "help" the belt to retract. Without the weight of the latch plate and friction to slow the retractive speed of the webbing, the higher than normal webbing retraction speed that occurs engages the locking mechanism when a sudden stop occurs at the end of web travel. Since the webbing is now fully loaded on the spool, the retractor cannot rewind itself further to release the locking mechanism. When this happens, the occupant cannot extract the belt to wear it. DO NOT replace the retractor for this condition until first attempting to disengage the locking mechanism by following the recommendation listed below. Recommendation Pull hard on the locked webbing and then release. The hard pull extracts a small amount of webbing from the retractor which, in turn, permits a small amount of retraction to occur when released. This is all that is needed to disengage the locking mechanism. The safety belt will now function properly. Vehicle Sensing This type of locking occurs in response to the vehicle under the following conditions: - The vehicle changes speed or direction abruptly (the vehicle goes into rapid acceleration OR rapid deceleration or there is aggressive cornering). - It can also occur in a static condition when a vehicle is parked on a large slant (fore-aft or side-to-side), such as streets in San Francisco, California. - It may also occur over rough road conditions where the retractor mechanism is bounced into a locked condition. In all of these conditions, as long as tension is maintained on the webbing, the belt will stay locked. When the tension is released, the belt retracts slightly, the lock bar disengages and the safety belt should return to normal function. Please inform customers that may comment that "the belt locks intermittently" that this is the design intent and the belt is functioning properly.

Seat Occupant Sensor Calibration Error Subject: Airbag System - Passenger Sensing # 07174 - (08/22/2007) Models: 2007 Chevrolet Equinox 2007 Pontiac Torrent Condition General Motors has decided that certain 2007 Chevrolet Equinox and Pontiac Torrent vehicles fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) 208, Occupant Crash Protection. In these vehicles, the right front passenger seat is built with a passenger sensing system. When tested with a representative, unrestrained, small adult, the system is required to turn the right front passenger's frontal airbag on. An error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag may not deploy. This could increase the occupant's risk of injury. In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. If the event of a crash, the frontal airbag could deploy and the child could be killed or seriously injured by the airbag. The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children. Correction Dealers are to reprogram the seat's electronic control unit (ECU). Vehicles Involved Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using GM Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may be involved. For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned. -- US dealers - GM DealerWorld Recall Information -- Export dealers - sent directly to dealers The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information No parts are required for this recall. Service Procedure Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration. The Passenger Presence System (PPS) is used to monitor the weight and pattern of an occupant on the front outboard passenger seat and communicate Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Restraint Systems > Sensors and Switches - Restraint Systems > Seat Occupant Sensor > Component Information > Technical Service Bulletins > Recalls: > 07174 > Aug > 07 > Recall - Seat Occupant Sensor Calibration Error > Page 14325 the status to the Sensing and Diagnostic module (SDM) whether to enable or suppress the deployment of the passenger airbag. The PPS consists of an electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators. Reprogram the electronic control module (ECU). Refer to the instructions below. Tech 2 Legacy or J2534 Pass-Thru programming method for the PPS Offset Reset (PPS) Important: If Tech 2 Legacy or J2534 Pass-Thru programming fails, call Techline Customer Support Center (TCSC) at 1-800-828-6860 (English) or 1-800-503-3222 (French). A "Candi" module is necessary. Calibration Information Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and TIS 2 Web with the calibration update. Use TIS 2 Web version 8.0 for 2007 (available on 08/07/07). If you cannot access the calibration, call the Techline Customer Support Center and it will be provided. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so. Make certain all tool connections are secure, including the following components and circuits: - The RS-232 communication cable port - The connection at the data link connector (DLC) - The voltage supply circuits DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. 1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. 2. Reprogram the electronic control module (ECU). Select PPS Offset Reset from the Supported Controller screen in TIS2Web. Refer to SI and Service Programming System (SPS) documentation for PSS programming instructions, if required.

Please discard Corporate Bulletin Number 06-08-50-009E (Section 08 - Body and Accessories). Concerns About Safety and Alterations to the Front Passenger Seat Important ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE THE SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT AS RELEASED BY GM FOR THAT VEHICLE. DO NOT ALTER THE SEAT COVERS OR SEAT-RELATED EQUIPMENT. ANY ALTERATIONS TO SEAT COVERS OR GM ACCESSORIES DEFEATS THE INTENDED DESIGN OF THE SYSTEM. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ALTERATIONS, INCLUDING ANY WARRANTY REPAIRS INCURRED. The front passenger seat in many GM vehicles is equipped with a passenger sensing system that will turn off the right front passenger's frontal airbag under certain conditions, such as when an infant or child seat is present. In some vehicles, the passenger sensing system will also turn off the right front passenger's seat mounted side impact airbag. For the system to function properly, sensors are used in the seat to detect the presence of a properly-seated occupant. The passenger sensing system may not operate properly if the original seat trim is replaced (1) by non-GM covers, upholstery or trim, or (2) by GM covers, upholstery or trim designed for a different vehicle or (3) by GM covers, upholstery or trim that has been altered by a trim shop, or (4) if any object, such as an aftermarket seat heater or a comfort enhancing pad or device is installed under the seat fabric or between the occupant and the seat fabric. Aftermarket Seat Heaters, Custom Upholstery, and Comfort Enhancing Pads or Devices Important ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE ONLY SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT RELEASED AS GM ACCESSORIES FOR THAT VEHICLE. DO NOT USE ANY OTHER TYPE OF SEAT COVERS OR SEAT-RELATED EQUIPMENT, OR GM ACCESSORIES RELEASED FOR OTHER VEHICLE APPLICATIONS. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ACCESSORIES, INCLUDING ANY WARRANTY REPAIRS MADE NECESSARY BY SUCH USE. Many types of aftermarket accessories are available to customers, upfitting shops, and dealers. Some of these devices sit on top of, or are Velcro(R) strapped to the seat while others such as seat heaters are installed under the seat fabric. Additionally, seat covers made of leather or other materials may have different padding thickness installed that could prevent the Passenger Sensing System from functioning properly. Never alter the vehicle seats. Never add pads or other devices to the seat cushion, as this may interfere with the operation of the Passenger Sensing System and either prevent proper deployment of the passenger airbag or prevent proper suppression of the passenger air bag.

Please discard Corporate Bulletin Number 06-08-50-009E (Section 08 - Body and Accessories). Concerns About Safety and Alterations to the Front Passenger Seat Important ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE THE SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT AS RELEASED BY GM FOR THAT VEHICLE. DO NOT ALTER THE SEAT COVERS OR SEAT-RELATED EQUIPMENT. ANY ALTERATIONS TO SEAT COVERS OR GM ACCESSORIES DEFEATS THE INTENDED DESIGN OF THE SYSTEM. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ALTERATIONS, INCLUDING ANY WARRANTY REPAIRS INCURRED. The front passenger seat in many GM vehicles is equipped with a passenger sensing system that will turn off the right front passenger's frontal airbag under certain conditions, such as when an infant or child seat is present. In some vehicles, the passenger sensing system will also turn off the right front passenger's seat mounted side impact airbag. For the system to function properly, sensors are used in the seat to detect the presence of a properly-seated occupant. The passenger sensing system may not operate properly if the original seat trim is replaced (1) by non-GM covers, upholstery or trim, or (2) by GM covers, upholstery or trim designed for a different vehicle or (3) by GM covers, upholstery or trim that has been altered by a trim shop, or (4) if any object, such as an aftermarket seat heater or a comfort enhancing pad or device is installed under the seat fabric or between the occupant and the seat fabric. Aftermarket Seat Heaters, Custom Upholstery, and Comfort Enhancing Pads or Devices Important ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE ONLY SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT RELEASED AS GM ACCESSORIES FOR THAT VEHICLE. DO NOT USE ANY OTHER TYPE OF SEAT COVERS OR SEAT-RELATED EQUIPMENT, OR GM ACCESSORIES RELEASED FOR OTHER VEHICLE APPLICATIONS. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ACCESSORIES, INCLUDING ANY WARRANTY REPAIRS MADE NECESSARY BY SUCH USE. Many types of aftermarket accessories are available to customers, upfitting shops, and dealers. Some of these devices sit on top of, or are Velcro(R) strapped to the seat while others such as seat heaters are installed under the seat fabric. Additionally, seat covers made of leather or other materials may have different padding thickness installed that could prevent the Passenger Sensing System from functioning properly. Never alter the vehicle seats. Never add pads or other devices to the seat cushion, as this may interfere with the operation of the Passenger Sensing System and either prevent proper deployment of the passenger airbag or prevent proper suppression of the passenger air bag.

Please discard Corporate Bulletin Number 01-07-31-002A (Section 07 - Transmission/Transaxle). This bulletin is being issued to inform dealers of an improved procedure to aid in the ease of bleeding the clutch hydraulic system for the above listed vehicles. This procedure can be used anytime air is introduced into the hydraulic system. Following this procedure may also reduce the number of unnecessary parts replaced for low clutch pedal reserve and high shift effort. Verify that all the lines and fittings are dry and secure. Clean the dirt and grease from the reservoir cap in order to ensure that no foreign substances enter the system. Remove the reservoir cap. Fill the reservoir to the proper level with the required fluid. Attach the J 43485 (Adapter) to the J 35555 (Mity Vac), or equivalent. Brake fluid will deteriorate the rubber on J 43485. Use a clean shop cloth to wipe away the fluid after each use. Place and hold the adapter on the reservoir filler neck to ensure a tight fit. In some cases, the adapter will fit into the reservoir opening. Apply a vacuum of 51-68 kPa (15-20 hg) and remove the adapter. Refill the reservoir to the proper level. Repeat Steps 6 and 7. If needed, refill the reservoir and continue to pull a vacuum until no more bubbles can be seen in the reservoir or until the fluid level no longer drops. The vehicle will move if started in gear before the Actuator Cylinder is refilled and operational. Start the vehicle the first time in neutral to help prevent personal injury from vehicle movement and see if the transmission will shift easily into gear. Pump the clutch pedal until firm (to refill actuator cylinder). Add additional fluid if needed. Test drive vehicle to ensure proper operation.

Condition Certain 2002-2009 model year vehicles equipped with OnStar(R) may have a condition in which the vehicle's OnStar(R) system repeatedly makes incomplete calls to OnStar(R) without the vehicle's occupant(s) input or knowledge. Customer initiated Blue Button call, Emergency calls, and Automatic Crash Notification calls will also fail to establish a data connection with the OnStar(R) Call Center. Eventually, the customer's call will connect as a voice only line and the customer will be able to talk with an OnStar(R) advisor; however, the advisor will not get crucial customer data such as vehicle identification and location. Correction Dealers/retailers are to replace the OnStar(R) module (VCIM). Vehicles Involved Involved are certain 2002-2009 model year vehicles equipped with OnStar(R), and built within these VIN breakpoints: Note: Some model years/models have only one vehicle involved. Important Dealers/retailers are to confirm vehicle eligibility prior to beginning repairs by using GMVIS (dealers/retailers using WINS) or the Investigate Vehicle History link (dealers/retailers using GWM). Not all vehicles within the above breakpoints may be involved. For dealers/retailers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided to dealers/retailers through the GM GlobalConnect Recall Reports. Dealers/retailers will not have a report available if they have no involved vehicles currently assigned. The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.

Please discard Corporate Bulletin Number 05-08-46-004B (Section 08 - Body and Accessories). During diagnosis of an OnStar(R) concern, the technician may be told that the OnStar(R) phone number is incorrect or tied to another vehicle and/or phone of some kind. To resolve these concerns, the Tech 2(R) with software version 22.005 (or higher), has the capability to change the OnStar(R) phone number. Service Procedure 1. With the Tech 2(R), build the vehicle to specifications within the Diagnostics area of the Tech 2(R). 2. For vehicles with physical-based diagnostics - under Body, go to the OnStar(R) section. Then select the Special Functions menu. For vehicles with functional-based diagnostics - under Body and Accessories, go to the Cellular Communication section. Select Module Setup and then Vehicle Communication Interface Module. 3. Locate the Program Phone Number prompt and select it. The original phone number will be displayed on the Tech 2(R) screen. 4. Contact the OnStar(R) team at the GM Technical Assistance Center (TAC) to obtain a new phone number. 5. Highlight the digits of the phone number one at a time and enter the new phone number using the number keys on the Tech 2(R). 6. Press the Soft key at the base of the screen for Done once these numbers have been changed on the screen. 7. Press the Soft key for Done again. The area code or new phone number has now been programmed into the phone. 8. Cycle the ignition to Off and open the driver's door. 9.

Please discard Corporate Bulletin Number 02-08-46-006B (Section 08 - Body and Accessories). A small number of the above-mentioned vehicles may exhibit a condition in which the vehicle reports an inaccurate location to the OnStar(R) Call Center. This condition can only be identified via a button press to the OnStar(R) Call Center by the customer. Call Center personnel will be able to identify this inaccurate location condition. Customers will then be notified through the mail by OnStar(R) if their vehicle exhibits this condition. Once this condition has been identified OnStar(R) will instruct the customer to return to the dealership to have this condition corrected. It is not necessary to reconfigure the vehicle after the following procedure. In order to correct this condition you must cycle power to the OnStar(R) system. This can be done by either removing the fuses powering the OnStar(R) system or disconnecting the OnStar(R) module (VCIM) from the vehicle. As a last resort you can disconnect the vehicle's battery. The power needs to be removed from the system for approximately 15 minutes. After completing this procedure the vehicle should be taken to an area with an unobstructed view of the sky. The vehicle should be kept running for approximately 10 minutes to allow the vehicle to reacquire the global positioning system (GPS). Then contact the OnStar(R) Call Center via the blue OnStar(R) button and ask the advisor to verify the GPS position. If the OnStar(R) advisor still has an inaccurate GPS location refer to the Navigation Systems and Cellular Communications sub-sections in the Service Manual in order to diagnose and repair the concern. If the normal diagnostics lead to module replacement you will need to contact Technical Assistance (TAC) and choose the OnStar(R) prompt. GM OnStar(R) TAC will assist in the diagnosis and if appropriate order a replacement part. Replacement parts are usually shipped out within 24 hours and a pre-paid return package label will be included for returning the faulty part. By returning the faulty part you will avoid a significant non-return core charge. Warranty Information (excluding Saab US Models) For vehicles repaired under warranty, use the table.

Please discard Corporate Bulletin Number 02-08-46-007B (Section 08 - Body & Accessories). If the vehicle currently has analog-upgradable OnStar(R) hardware, then the customer should be made aware of the digital upgrade program per the latest version of Service Bulletin # 05-08-46-006. Any analog OnStar system that is not upgraded prior to the end of 2007 will be deactivated due to the upcoming phase-out of the analog cellular network in the U.S. and Canada. If the vehicle has recently been upgraded or has had a service replacement unit installed, this bulletin may not be applicable. Certain 2001-2008 model year vehicles equipped with OnStar(R) may exhibit a condition with the Global Positioning System (GPS) that causes inaccuracies in the GPS clock. The GPS system is internal to the OnStar(R) Vehicle Interface Unit (VIU) or the Vehicle Communication Interface Module (VCIM). This inaccuracy can result in a symptom where the OnStar(R) Call Center is unable to obtain an accurate GPS signal, hands-Free Calling minutes expire prematurely and/or the inability to add Hands-Free calling minutes. Customer Notification OnStar(R) will notify the customer by mail with instructions to contact their dealership service department. Dealer Action Not all vehicles will require VIU/VCIM replacement. The GPS signal in some vehicles may be recoverable. To determine if the signal is recoverable, simply connect the Tech2(R) and using the GPS information data display option, observe the GPS date and time. If the date/time stamps are equal to a date approximately 19 years in the future, the GPS clock has exceeded its capacity and the VIU/VCIM will need to be replaced. If the date/time stamp is in the past or near future, the GPS clock has simply generated an inaccurate value and may be recoverable by performing the following power-up reset. To initiate a power-up reset, battery voltage (batt. +) must be removed from the VIU/VCIM. The preferred methods, in order, of initiating the reset are outlined below. Remove the fuse that supplies Battery positive (Batt. +) voltage to the module (refer to the applicable Service Information schematics for the appropriate fuse). The next preferred method is to remove the connector to the OnStar(R) unit that Batt + is contained. The least preferable method is to remove the negative terminal of the vehicle battery. This will not only initiate the power-up reset, but it may also result in the loss of radio presets and other stored personalization information/settings in other modules as well. After initiating the power-up reset, the GPS data will be set to the defaulted date and time and will require an acquisition of the GPS signal in order to gain the proper date and time. Acquiring the GPS signal requires running the vehicle in an open/unobstructed view of the sky. First, contact OnStar(R) Technical Support by pressing the blue button. Allow the OnStar(R) Technical Advisor to activate the GPS recovery process. This should take approximately 10 minutes.

Certain aftermarket devices, when connected to the Diagnostic Link Connector, such as, but not limited to, Scan Tools, Trip Computers, Fuel Economy Analyzers and Insurance Tracking Devices, interfere with OnStar's ability to perform a diagnostic probe when requested (via a blue button call) by a subscriber. These devices also prohibit the ability to gather diagnostic and tire pressure data for a subscriber's scheduled OnStar(R) Vehicle Diagnostic (OVD) e-mail. These aftermarket devices utilize the Vehicles serial data bus to perform data requests and/or information gathering. When these devices are requesting data, OnStar(R) is designed not to interfere with any data request being made by these devices as required by OBD II regulations. The OnStar(R) advisor is unable to definitively detect the presence of these devices and will only be able to inform the caller or requester of the unsuccessful or incomplete probe and may in some cases refer the subscriber/requester to take the vehicle to a dealer for diagnosis of the concern. When performing a diagnostic check for an unsuccessful or incomplete OnStar(R) diagnostic probe, or for concerns regarding completeness of the OnStar(R) Vehicle Diagnostic (OVD) e-mail, verify that an aftermarket device was not present at the time of the requested probe. Regarding the OVD e-mail, if an aftermarket device is interfering (including a Scan Tool of any type), the e-mail will consistently display a "yellow" indication in diagnostics section for all vehicle systems except the OnStar(R) System and Tire Pressure data (not available on all vehicles) will not be displayed (i.e. section is collapsed). Successful diagnostic probes and complete OVD e-mails will resume following the removal or disconnecting of the off-board device.

A small number of the above-mentioned vehicles may exhibit a condition in which the vehicle reports an inaccurate location to the OnStar(R) Call Center. This condition can only be identified via a button press to the OnStar(R) Call Center by the customer. Call Center personnel will be able to identify this inaccurate location condition. Customers will then be notified through the mail by OnStar(R) if their vehicle exhibits this condition. Once this condition has been identified OnStar(R) will instruct the customer to return to the dealership to have this condition corrected. It is not necessary to reconfigure the vehicle after the following procedure. In order to correct this condition you must cycle power to the OnStar(R) system. This can be done by either removing the fuses powering the OnStar(R) system or disconnecting the OnStar(R) module (VCIM) from the vehicle. As a last resort you can disconnect the vehicle's battery. The power needs to be removed from the system for approximately 15 minutes. After completing this procedure the vehicle should be taken to an area with an unobstructed view of the sky. The vehicle should be kept running for approximately 10 minutes to allow the vehicle to reacquire the global positioning system (GPS). Then contact the OnStar(R) Call Center via the blue OnStar(R) button and ask the advisor to verify the GPS position. If the OnStar(R) advisor still has an inaccurate GPS location refer to the Navigation Systems and Cellular Communications sub-sections in the Service Manual in order to diagnose and repair the concern. If the normal diagnostics lead to module replacement you will need to contact Technical Assistance (TAC) and choose the OnStar(R) prompt. GM OnStar(R) TAC will assist in the diagnosis and if appropriate order a replacement part.

Certain aftermarket devices, when connected to the Diagnostic Link Connector, such as, but not limited to, Scan Tools, Trip Computers, Fuel Economy Analyzers and Insurance Tracking Devices, interfere with OnStar's ability to perform a diagnostic probe when requested (via a blue button call) by a subscriber. These devices also prohibit the ability to gather diagnostic and tire pressure data for a subscriber's scheduled OnStar(R) Vehicle Diagnostic (OVD) e-mail. These aftermarket devices utilize the Vehicles serial data bus to perform data requests and/or information gathering. When these devices are requesting data, OnStar(R) is designed not to interfere with any data request being made by these devices as required by OBD II regulations. The OnStar(R) advisor is unable to definitively detect the presence of these devices and will only be able to inform the caller or requester of the unsuccessful or incomplete probe and may in some cases refer the subscriber/requester to take the vehicle to a dealer for diagnosis of the concern. When performing a diagnostic check for an unsuccessful or incomplete OnStar(R) diagnostic probe, or for concerns regarding completeness of the OnStar(R) Vehicle Diagnostic (OVD) e-mail, verify that an aftermarket device was not present at the time of the requested probe. Regarding the OVD e-mail, if an aftermarket device is interfering (including a Scan Tool of any type), the e-mail will consistently display a "yellow" indication in diagnostics section for all vehicle systems except the OnStar(R) System and Tire Pressure data (not available on all vehicles) will not be displayed (i.e. section is collapsed). Successful diagnostic probes and complete OVD e-mails will resume following the removal or disconnecting of the off-board device.

Please discard Corporate Bulletin Number 00-08-46-004B (Section 08 - Body and Accessories). When servicing any of the above models and a battery cable is disconnected or power to the OnStar(R) Vehicle Communication Interface Module (VCIM) is interrupted for any reason the following procedure must be performed to verify proper Global Positioning System (GPS) function. Never swap OnStar(R) Vehicle Communication Interface Modules (VCIM) from other vehicles. Transfer of OnStar(R) modules from other vehicles should not be done. Each OnStar(R) module has a unique identification number. The VCIM has a specific Station Identification (STID). This identification number is used by the National Cellular Telephone Network and OnStar(R) systems and is stored in General Motors Vehicle History files by VIN. After completing ALL repairs to the vehicle you must perform the following procedure: Move the vehicle into an open area of the service lot. Sit in the vehicle with the engine running and the radio turned on for five minutes. Press the OnStar(R) button in the vehicle. When the OnStar(R) advisor answers ask the advisor to verify the current location of the vehicle. If the vehicle location is different than the location the OnStar(R) advisor gives contact GM Technical Assistance (TAC) and choose the OnStar(R) prompt. GM OnStar(R) TAC will assist in the diagnosis of a failed VCIM and, if appropriate, order a replacement part. Replacement parts are usually shipped out within 24 hours, and a pre-paid return package label will be included for returning the faulty part. By returning the faulty part, you will avoid a non-return core charge.

Please discard Corporate Bulletin Number 02-08-46-006B (Section 08 - Body and Accessories). A small number of the above-mentioned vehicles may exhibit a condition in which the vehicle reports an inaccurate location to the OnStar(R) Call Center. This condition can only be identified via a button press to the OnStar(R) Call Center by the customer. Call Center personnel will be able to identify this inaccurate location condition. Customers will then be notified through the mail by OnStar(R) if their vehicle exhibits this condition. Once this condition has been identified OnStar(R) will instruct the customer to return to the dealership to have this condition corrected. It is not necessary to reconfigure the vehicle after the following procedure. In order to correct this condition you must cycle power to the OnStar(R) system. This can be done by either removing the fuses powering the OnStar(R) system or disconnecting the OnStar(R) module (VCIM) from the vehicle. As a last resort you can disconnect the vehicle's battery. The power needs to be removed from the system for approximately 15 minutes. After completing this procedure the vehicle should be taken to an area with an unobstructed view of the sky. The vehicle should be kept running for approximately 10 minutes to allow the vehicle to reacquire the global positioning system (GPS). Then contact the OnStar(R) Call Center via the blue OnStar(R) button and ask the advisor to verify the GPS position. If the OnStar(R) advisor still has an inaccurate GPS location refer to the Navigation Systems and Cellular Communications sub-sections in the Service Manual in order to diagnose and repair the concern. If the normal diagnostics lead to module replacement you will need to contact Technical Assistance (TAC) and choose the OnStar(R) prompt. GM OnStar(R) TAC will assist in the diagnosis and if appropriate order a replacement part. Replacement parts are usually shipped out within 24 hours and a pre-paid return package label will be included for returning the faulty part.

Please discard Corporate Bulletin Number 02-08-46-007B (Section 08 - Body & Accessories). If the vehicle currently has analog-upgradable OnStar(R) hardware, then the customer should be made aware of the digital upgrade program per the latest version of Service Bulletin # 05-08-46-006. Any analog OnStar system that is not upgraded prior to the end of 2007 will be deactivated due to the upcoming phase-out of the analog cellular network in the U.S. and Canada. If the vehicle has recently been upgraded or has had a service replacement unit installed, this bulletin may not be applicable. Certain 2001-2008 model year vehicles equipped with OnStar(R) may exhibit a condition with the Global Positioning System (GPS) that causes inaccuracies in the GPS clock. The GPS system is internal to the OnStar(R) Vehicle Interface Unit (VIU) or the Vehicle Communication Interface Module (VCIM). This inaccuracy can result in a symptom where the OnStar(R) Call Center is unable to obtain an accurate GPS signal, hands-Free Calling minutes expire prematurely and/or the inability to add Hands-Free calling minutes. Customer Notification OnStar(R) will notify the customer by mail with instructions to contact their dealership service department. Dealer Action Not all vehicles will require VIU/VCIM replacement. The GPS signal in some vehicles may be recoverable. To determine if the signal is recoverable, simply connect the Tech2(R) and using the GPS information data display option, observe the GPS date and time. If the date/time stamps are equal to a date approximately 19 years in the future, the GPS clock has exceeded its capacity and the VIU/VCIM will need to be replaced. If the date/time stamp is in the past or near future, the GPS clock has simply generated an inaccurate value and may be recoverable by performing the following power-up reset. To initiate a power-up reset, battery voltage (batt. +) must be removed from the VIU/VCIM. The preferred methods, in order, of initiating the reset are outlined below. Remove the fuse that supplies Battery positive (Batt. +) voltage to the module (refer to the applicable Service Information schematics for the appropriate fuse). The next preferred method is to remove the connector to the OnStar(R) unit that Batt + is contained. The least preferable method is to remove the negative terminal of the vehicle battery. This will not only initiate the power-up reset, but it may also result in the loss of radio presets and other stored personalization information/settings in other modules as well. After initiating the power-up reset, the GPS data will be set to the defaulted date and time and will require an acquisition of the GPS signal in order to gain the proper date and time. Acquiring the GPS signal requires running the vehicle in an open/unobstructed view of the sky. First, contact OnStar(R) Technical Support by pressing the blue button. Allow the OnStar(R) Technical Advisor to activate the GPS recovery process. This should take approximately 10 minutes.

REMINDER - Keep in mind that the time displayed on the Tech2(R) is in Greenwich Mean Time (GMT) and the offset is based on the time zones relationship to GMT. If replacement of the VIU/VCIM is necessary, you MUST reconfigure the OnStar® system. Failure to reconfigure the system will result in an additional customer visit for repair. OnStar® VIU, Generations 2 and 3, will require the technician to press the blue OnStar® button to reconfigure the vehicle with an OnStar® advisor. OnStar(R) VCIM, Generations 4-7 will require the technician to reconfigure the vehicle with the use of the TIS2WEB and SPS applications (pass thru only), along with the Tech2(R). The configuration and set-up procedure is a two-step process that must be completed step-by-step without interruption or delay in between each step. This procedure enables an automated activation without a button press by the technician to the OnStar(R) Call Center. Following this procedure, it may take up to 24 hours for all OnStar(R) services to be fully activated. How to Order Parts If the OnStar(R) GPS date/time stamp is non-recoverable and the unit needs to be replaced, dealers in the U.S. should contact Autocraft Electronics select the catalog item that contains this bulletin number. Canadian dealers should contact MASS Electronics. Dealers DO NOT need to call the GM Technical Assistance Center (TAC) for replacement approval. Autocraft Electronics and MASS Electronics will be responsible for verifying that the subject vehicle is a candidate for a replacement VIU/VCIM.

Certain aftermarket devices, when connected to the Diagnostic Link Connector, such as, but not limited to, Scan Tools, Trip Computers, Fuel Economy Analyzers and Insurance Tracking Devices, interfere with OnStar's ability to perform a diagnostic probe when requested (via a blue button call) by a subscriber. These devices also prohibit the ability to gather diagnostic and tire pressure data for a subscriber's scheduled OnStar(R) Vehicle Diagnostic (OVD) e-mail. These aftermarket devices utilize the Vehicles serial data bus to perform data requests and/or information gathering. When these devices are requesting data, OnStar(R) is designed not to interfere with any data request being made by these devices as required by OBD II regulations. The OnStar(R) advisor is unable to definitively detect the presence of these devices and will only be able to inform the caller or requester of the unsuccessful or incomplete probe and may in some cases refer the subscriber/requester to take the vehicle to a dealer for diagnosis of the concern. When performing a diagnostic check for an unsuccessful or incomplete OnStar(R) diagnostic probe, or for concerns regarding completeness of the OnStar(R) Vehicle Diagnostic (OVD) e-mail, verify that an aftermarket device was not present at the time of the requested probe. Regarding the OVD e-mail, if an aftermarket device is interfering (including a Scan Tool of any type), the e-mail will consistently display a "yellow" indication in diagnostics section for all vehicle systems except the OnStar(R) System and Tire Pressure data (not available on all vehicles) will not be displayed (i.e. section is collapsed).

Please discard Corporate Bulletin Number 02-08-46-007B (Section 08 - Body & Accessories). If the vehicle currently has analog-upgradable OnStar(R) hardware, then the customer should be made aware of the digital upgrade program per the latest version of Service Bulletin # 05-08-46-006. Any analog OnStar system that is not upgraded prior to the end of 2007 will be deactivated due to the upcoming phase-out of the analog cellular network in the U.S. and Canada. If the vehicle has recently been upgraded or has had a service replacement unit installed, this bulletin may not be applicable. Certain 2001-2008 model year vehicles equipped with OnStar(R) may exhibit a condition with the Global Positioning System (GPS) that causes inaccuracies in the GPS clock. The GPS system is internal to the OnStar(R) Vehicle Interface Unit (VIU) or the Vehicle Communication Interface Module (VCIM). This inaccuracy can result in a symptom where the OnStar(R) Call Center is unable to obtain an accurate GPS signal, hands-Free Calling minutes expire prematurely and/or the inability to add Hands-Free calling minutes. Customer Notification OnStar(R) will notify the customer by mail with instructions to contact their dealership service department. Dealer Action Not all vehicles will require VIU/VCIM replacement. The GPS signal in some vehicles may be recoverable. To determine if the signal is recoverable, simply connect the Tech2(R) and using the GPS information data display option, observe the GPS date and time. If the date/time stamps are equal to a date approximately 19 years in the future, the GPS clock has exceeded its capacity and the VIU/VCIM will need to be replaced. If the date/time stamp is in the past or near future, the GPS clock has simply generated an inaccurate value and may be recoverable by performing the following power-up reset. To initiate a power-up reset, battery voltage (batt. +) must be removed from the VIU/VCIM. The preferred methods, in order, of initiating the reset are outlined below. Remove the fuse that supplies Battery positive (Batt. +) voltage to the module (refer to the applicable Service Information schematics for the appropriate fuse). The next preferred method is to remove the connector to the OnStar(R) unit that Batt + is contained. The least preferable method is to remove the negative terminal of the vehicle battery. This will not only initiate the power-up reset, but it may also result in the loss of radio presets and other stored personalization information/settings in other modules as well. After initiating the power-up reset, the GPS data will be set to the defaulted date and time and will require an acquisition of the GPS signal in order to gain the proper date and time. Acquiring the GPS signal requires running the vehicle in an open/unobstructed view of the sky. First, contact OnStar(R) Technical Support by pressing the blue button. Allow the OnStar(R) Technical Advisor to activate the GPS recovery process. This should take approximately 10 minutes.

REMINDER - Keep in mind that the time displayed on the Tech2(R) is in Greenwich Mean Time (GMT) and the offset is based on the time zones relationship to GMT. If replacement of the VIU/VCIM is necessary, you MUST reconfigure the OnStar® system. Failure to reconfigure the system will result in an additional customer visit for repair. OnStar® VIU, Generations 2 and 3, will require the technician to press the blue OnStar® button to reconfigure the vehicle with an OnStar® advisor. OnStar(R) VCIM, Generations 4-7 will require the technician to reconfigure the vehicle with the use of the TIS2WEB and SPS applications (pass thru only), along with the Tech2(R). The configuration and set-up procedure is a two-step process that must be completed step-by-step without interruption or delay in between each step. This procedure enables an automated activation without a button press by the technician to the OnStar(R) Call Center. Following this procedure, it may take up to 24 hours for all OnStar(R) services to be fully activated. How to Order Parts If the OnStar(R) GPS date/time stamp is non-recoverable and the unit needs to be replaced, dealers in the U.S. should contact Autocraft Electronics select the catalog item that contains this bulletin number. Canadian dealers should contact MASS Electronics. Dealers DO NOT need to call the GM Technical Assistance Center (TAC) for replacement approval. Autocraft Electronics and MASS Electronics will be responsible for verifying that the subject vehicle is a candidate for a replacement VIU/VCIM.

Certain aftermarket devices, when connected to the Diagnostic Link Connector, such as, but not limited to, Scan Tools, Trip Computers, Fuel Economy Analyzers and Insurance Tracking Devices, interfere with OnStar's ability to perform a diagnostic probe when requested (via a blue button call) by a subscriber. These devices also prohibit the ability to gather diagnostic and tire pressure data for a subscriber's scheduled OnStar(R) Vehicle Diagnostic (OVD) e-mail. These aftermarket devices utilize the Vehicles serial data bus to perform data requests and/or information gathering. When these devices are requesting data, OnStar(R) is designed not to interfere with any data request being made by these devices as required by OBD II regulations. The OnStar(R) advisor is unable to definitively detect the presence of these devices and will only be able to inform the caller or requester of the unsuccessful or incomplete probe and may in some cases refer the subscriber/requester to take the vehicle to a dealer for diagnosis of the concern. When performing a diagnostic check for an unsuccessful or incomplete OnStar(R) diagnostic probe, or for concerns regarding completeness of the OnStar(R) Vehicle Diagnostic (OVD) e-mail, verify that an aftermarket device was not present at the time of the requested probe. Regarding the OVD e-mail, if an aftermarket device is interfering (including a Scan Tool of any type), the e-mail will consistently display a "yellow" indication in diagnostics section for all vehicle systems except the OnStar(R) System and Tire Pressure data (not available on all vehicles) will not be displayed (i.e. section is collapsed). Successful diagnostic probes and complete OVD e-mails will resume following the removal or disconnecting of the off-board device.

When servicing any of the above models and a battery cable is disconnected or power to the OnStar(R) Vehicle Communication Interface Module (VCIM) is interrupted for any reason the following procedure must be performed to verify proper Global Positioning System (GPS) function. Never swap OnStar(R) Vehicle Communication Interface Modules (VCIM) from other vehicles. Transfer of OnStar(R) modules from other vehicles should not be done. Each OnStar(R) module has a unique identification number. The VCIM has a specific Station Identification (STID). This identification number is used by the National Cellular Telephone Network and OnStar(R) systems and is stored in General Motors Vehicle History files by VIN. After completing ALL repairs to the vehicle you must perform the following procedure: Move the vehicle into an open area of the service lot. Sit in the vehicle with the engine running and the radio turned on for five minutes. Press the OnStar(R) button in the vehicle. When the OnStar(R) advisor answers ask the advisor to verify the current location of the vehicle. If the vehicle location is different than the location the OnStar(R) advisor gives contact GM Technical Assistance (TAC) and choose the OnStar(R) prompt. GM OnStar(R) TAC will assist in the diagnosis of a failed VCIM and, if appropriate, order a replacement part. Replacement parts are usually shipped out within 24 hours, and a pre-paid return package label will be included for returning the faulty part. By returning the faulty part, you will avoid a non-return core charge.

Disclaimer Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Accessories and Optional Equipment > Pedal Positioning System > Pedal Positioning Sensor > Component Information > Service and Repair > Procedures Pedal Positioning Sensor: Procedures BRAKE PEDAL POSITION SENSOR CALIBRATION CALIBRATION CRITERIA The brake pedal position sensor (BPPS) receives a low reference signal and a 5-volt reference signal from the BCM. Whenever the brake pedal is applied, the BPPS applies a variable voltage signal to the BCM through the stop lamp switch signal circuit. The BPPS calibration must be performed after the BPPS or body control module (BCM) have been serviced. The calibration procedure will set BPPS home value. This value is used by the BCM to determine the action of the driver applying the brake system and to provide this information to the vehicle subsystems via the communication bus. CALIBRATION PROCEDURE - Install a scan tool. - Turn ON the ignition, with the engine OFF. - Select Diagnostics. - Select the year. - Select the vehicle type. - Select BCM. - Select Module Setup. - Select the BPPS calibration procedure and follow the directions displayed on the screen.

Store them in their original cases or other protective cases and away from direct sunlight and dust. The CD player scans the bottom surface of the disc. If the surface of a CD is damaged, such as cracked, broken, scratched, or wrinkled labeling, the CD will not play properly or not at all. If the surface of a CD is soiled, take a soft, lint free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water, and clean it. Make sure the wiping process starts from the center to the edge. Do not touch the bottom side of a CD while handling it. This could damage the surface. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge. Care of the CD Player The use of CD lens cleaners for CD players is not advised, due to the risk of contaminating the internal lens of the CD optics with lubricants. Stuck CDs Interrupting the battery power by pulling the fuse will sometimes release a stuck CD. If a CD is stuck, and removed, inspect it for warps, cracks, etc. If the CD is damaged, do not replace the radio. Labeling CDs Paper labels can eventually warp and wrinkle, and this will cause the disc to jam inside the CD player. Try labeling the top of the discs with a soft magic marker instead.

Please discard Corporate Bulletin Number 07-08-46-002C (Section 08 - Body and Accessories). Condition Some customers may comment on an audio whine coming from the radio speakers when using the OnStar(R) system. The amplitude and frequency of the whine will change with an increase or decrease in engine speed. Cause This condition may be caused by electrical noise on the OnStar(R) Vehicle Communication Interface Module (VCIM) battery feed wire being passed to the microphone output pins at the radio. Correction Technicians are to install a noise suppression filter, P/N 1224205, into the OnStar(R) battery voltage circuit, a few centimeters (inches) from the VCIM. The filter package has three attached wires - a single yellow wire at one end with a yellow wire and a black wire at the other. Install the single yellow wire side into the battery voltage circuit towards the VCIM. Install the remaining single yellow wire into the battery voltage circuit toward the fuse and the black wire to ground. Important The noise suppression filter is polarity sensitive. The filter is designed to be most effective when the end with the capacitor ground is connected towards the source of the electrical noise. Install the filter in this polarity first. If the noise level is still not satisfactory, try disconnecting the capacitor ground. In some cases, if the first installation does not correct the noise, try reversing the filter polarity (removing the filter, turning it end for end and then reinstalling it) and grounding the capacitor lead.

Please discard Corporate Bulletin Number 02-08-46-006B (Section 08 - Body and Accessories). A small number of the above-mentioned vehicles may exhibit a condition in which the vehicle reports an inaccurate location to the OnStar(R) Call Center. This condition can only be identified via a button press to the OnStar(R) Call Center by the customer. Call Center personnel will be able to identify this inaccurate location condition. Customers will then be notified through the mail by OnStar(R) if their vehicle exhibits this condition. Once this condition has been identified OnStar(R) will instruct the customer to return to the dealership to have this condition corrected. It is not necessary to reconfigure the vehicle after the following procedure. In order to correct this condition you must cycle power to the OnStar(R) system. This can be done by either removing the fuses powering the OnStar(R) system or disconnecting the OnStar(R) module (VCIM) from the vehicle. As a last resort you can disconnect the vehicle's battery. The power needs to be removed from the system for approximately 15 minutes. After completing this procedure the vehicle should be taken to an area with an unobstructed view of the sky. The vehicle should be kept running for approximately 10 minutes to allow the vehicle to reacquire the global positioning system (GPS). Then contact the OnStar(R) Call Center via the blue OnStar(R) button and ask the advisor to verify the GPS position. If the OnStar(R) advisor still has an inaccurate GPS location refer to the Navigation Systems and Cellular Communications sub-sections in the Service Manual in order to diagnose and repair the concern. If the normal diagnostics lead to module replacement you will need to contact Technical Assistance (TAC) and choose the OnStar(R) prompt. GM OnStar(R) TAC will assist in the diagnosis and if appropriate order a replacement part. Replacement parts are usually shipped out within 24 hours and a pre-paid return package label will be included for returning the faulty part. By returning the faulty part you will avoid a significant non-return core charge. Warranty Information (excluding Saab US Models) For vehicles repaired under warranty, use the table.

Please discard Corporate Bulletin Number 02-08-46-007B (Section 08 - Body & Accessories). If the vehicle currently has analog-upgradable OnStar(R) hardware, then the customer should be made aware of the digital upgrade program per the latest version of Service Bulletin # 05-08-46-006. Any analog OnStar system that is not upgraded prior to the end of 2007 will be deactivated due to the upcoming phase-out of the analog cellular network in the U.S. and Canada. If the vehicle has recently been upgraded or has had a service replacement unit installed, this bulletin may not be applicable. Certain 2001-2008 model year vehicles equipped with OnStar(R) may exhibit a condition with the Global Positioning System (GPS) that causes inaccuracies in the GPS clock. The GPS system is internal to the OnStar(R) Vehicle Interface Unit (VIU) or the Vehicle Communication Interface Module (VCIM). This inaccuracy can result in a symptom where the OnStar(R) Call Center is unable to obtain an accurate GPS signal, hands-Free Calling minutes expire prematurely and/or the inability to add Hands-Free calling minutes. Customer Notification OnStar(R) will notify the customer by mail with instructions to contact their dealership service department. Dealer Action Not all vehicles will require VIU/VCIM replacement. The GPS signal in some vehicles may be recoverable. To determine if the signal is recoverable, simply connect the Tech2(R) and using the GPS information data display option, observe the GPS date and time. If the date/time stamps are equal to a date approximately 19 years in the future, the GPS clock has exceeded its capacity and the VIU/VCIM will need to be replaced. If the date/time stamp is in the past or near future, the GPS clock has simply generated an inaccurate value and may be recoverable by performing the following power-up reset. To initiate a power-up reset, battery voltage (batt. +) must be removed from the VIU/VCIM. The preferred methods, in order, of initiating the reset are outlined below. Remove the fuse that supplies Battery positive (Batt. +) voltage to the module (refer to the applicable Service Information schematics for the appropriate fuse). The next preferred method is to remove the connector to the OnStar(R) unit that Batt + is contained. The least preferable method is to remove the negative terminal of the vehicle battery. This will not only initiate the power-up reset, but it may also result in the loss of radio presets and other stored personalization information/settings in other modules as well. After initiating the power-up reset, the GPS data will be set to the defaulted date and time and will require an acquisition of the GPS signal in order to gain the proper date and time. Acquiring the GPS signal requires running the vehicle in an open/unobstructed view of the sky. First, contact OnStar(R) Technical Support by pressing the blue button. Allow the OnStar(R) Technical Advisor to activate the GPS recovery process. This should take approximately 10 minutes.

REMINDER - Keep in mind that the time displayed on the Tech2(R) is in Greenwich Mean Time (GMT) and the offset is based on the time zones relationship to GMT. If replacement of the VIU/VCIM is necessary, you MUST reconfigure the OnStar® system. Failure to reconfigure the system will result in an additional customer visit for repair. OnStar® VIU, Generations 2 and 3, will require the technician to press the blue OnStar® button to reconfigure the vehicle with an OnStar® advisor. OnStar(R) VCIM, Generations 4-7 will require the technician to reconfigure the vehicle with the use of the TIS2WEB and SPS applications (pass thru only), along with the Tech2(R). The configuration and set-up procedure is a two-step process that must be completed step-by-step without interruption or delay in between each step. This procedure enables an automated activation without a button press by the technician to the OnStar(R) Call Center. Following this procedure, it may take up to 24 hours for all OnStar(R) services to be fully activated. How to Order Parts If the OnStar(R) GPS date/time stamp is non-recoverable and the unit needs to be replaced, dealers in the U.S. should contact Autocraft Electronics select the catalog item that contains this bulletin number. Canadian dealers should contact MASS Electronics. Dealers DO NOT need to call the GM Technical Assistance Center (TAC) for replacement approval. Autocraft Electronics and MASS Electronics will be responsible for verifying that the subject vehicle is a candidate for a replacement VIU/VCIM.

A small number of the above-mentioned vehicles may exhibit a condition in which the vehicle reports an inaccurate location to the OnStar(R) Call Center. This condition can only be identified via a button press to the OnStar(R) Call Center by the customer. Call Center personnel will be able to identify this inaccurate location condition. Customers will then be notified through the mail by OnStar(R) if their vehicle exhibits this condition. Once this condition has been identified OnStar(R) will instruct the customer to return to the dealership to have this condition corrected. It is not necessary to reconfigure the vehicle after the following procedure. In order to correct this condition you must cycle power to the OnStar(R) system. This can be done by either removing the fuses powering the OnStar(R) system or disconnecting the OnStar(R) module (VCIM) from the vehicle. As a last resort you can disconnect the vehicle's battery. The power needs to be removed from the system for approximately 15 minutes. After completing this procedure the vehicle should be taken to an area with an unobstructed view of the sky. The vehicle should be kept running for approximately 10 minutes to allow the vehicle to reacquire the global positioning system (GPS). Then contact the OnStar(R) Call Center via the blue OnStar(R) button and ask the advisor to verify the GPS position. If the OnStar(R) advisor still has an inaccurate GPS location refer to the Navigation Systems and Cellular Communications sub-sections in the Service Manual in order to diagnose and repair the concern. If the normal diagnostics lead to module replacement you will need to contact Technical Assistance (TAC) and choose the OnStar(R) prompt. GM OnStar(R) TAC will assist in the diagnosis and if appropriate order a replacement part. Replacement parts are usually shipped out within 24 hours and a pre-paid return package label will be included for returning the faulty part.

Please discard Corporate Bulletin Number 02-08-46-007B (Section 08 - Body & Accessories). If the vehicle currently has analog-upgradable OnStar(R) hardware, then the customer should be made aware of the digital upgrade program per the latest version of Service Bulletin # 05-08-46-006. Any analog OnStar system that is not upgraded prior to the end of 2007 will be deactivated due to the upcoming phase-out of the analog cellular network in the U.S. and Canada. If the vehicle has recently been upgraded or has had a service replacement unit installed, this bulletin may not be applicable. Certain 2001-2008 model year vehicles equipped with OnStar(R) may exhibit a condition with the Global Positioning System (GPS) that causes inaccuracies in the GPS clock. The GPS system is internal to the OnStar(R) Vehicle Interface Unit (VIU) or the Vehicle Communication Interface Module (VCIM). This inaccuracy can result in a symptom where the OnStar(R) Call Center is unable to obtain an accurate GPS signal, hands-Free Calling minutes expire prematurely and/or the inability to add Hands-Free calling minutes. Customer Notification OnStar(R) will notify the customer by mail with instructions to contact their dealership service department. Dealer Action Not all vehicles will require VIU/VCIM replacement. The GPS signal in some vehicles may be recoverable. To determine if the signal is recoverable, simply connect the Tech2(R) and using the GPS information data display option, observe the GPS date and time. If the date/time stamps are equal to a date approximately 19 years in the future, the GPS clock has exceeded its capacity and the VIU/VCIM will need to be replaced. If the date/time stamp is in the past or near future, the GPS clock has simply generated an inaccurate value and may be recoverable by performing the following power-up reset. To initiate a power-up reset, battery voltage (batt. +) must be removed from the VIU/VCIM. The preferred methods, in order, of initiating the reset are outlined below. Remove the fuse that supplies Battery positive (Batt. +) voltage to the module (refer to the applicable Service Information schematics for the appropriate fuse). The next preferred method is to remove the connector to the OnStar(R) unit that Batt + is contained. The least preferable method is to remove the negative terminal of the vehicle battery. This will not only initiate the power-up reset, but it may also result in the loss of radio presets and other stored personalization information/settings in other modules as well. After initiating the power-up reset, the GPS data will be set to the defaulted date and time and will require an acquisition of the GPS signal in order to gain the proper date and time. Acquiring the GPS signal requires running the vehicle in an open/unobstructed view of the sky. First, contact OnStar(R) Technical Support by pressing the blue button. Allow the OnStar(R) Technical Advisor to activate the GPS recovery process. This should take approximately 10 minutes.

REMINDER - Keep in mind that the time displayed on the Tech2(R) is in Greenwich Mean Time (GMT) and the offset is based on the time zones relationship to GMT. If replacement of the VIU/VCIM is necessary, you MUST reconfigure the OnStar® system. Failure to reconfigure the system will result in an additional customer visit for repair. OnStar® VIU, Generations 2 and 3, will require the technician to press the blue OnStar® button to reconfigure the vehicle with an OnStar® advisor. OnStar(R) VCIM, Generations 4-7 will require the technician to reconfigure the vehicle with the use of the TIS2WEB and SPS applications (pass thru only), along with the Tech2(R). The configuration and set-up procedure is a two-step process that must be completed step-by-step without interruption or delay in between each step. This procedure enables an automated activation without a button press by the technician to the OnStar(R) Call Center. Following this procedure, it may take up to 24 hours for all OnStar(R) services to be fully activated. How to Order Parts If the OnStar(R) GPS date/time stamp is non-recoverable and the unit needs to be replaced, dealers in the U.S. should contact Autocraft Electronics select the catalog item that contains this bulletin number. Canadian dealers should contact MASS Electronics. Dealers DO NOT need to call the GM Technical Assistance Center (TAC) for replacement approval. Autocraft Electronics and MASS Electronics will be responsible for verifying that the subject vehicle is a candidate for a replacement VIU/VCIM.

Refer to the end of this bulletin for identification information to determine type of transfer case. The vehicles shown should NOT be dinghy towed because the transfer cases in these vehicles either have no neutral position or do not have an internal oil pump to provide lubrication while being towed. In order to properly tow the vehicles, place the vehicle on a platform trailer with all four tires off the ground. Avoid towing the vehicle with all four tires on the ground. In rare instances when towing with all four tires on the ground is unavoidable, both the front and the rear propeller shafts must be removed in order to prevent damage to the transfer case and/or transmission. Because front and rear propeller shafts are matched to attaching components at assembly, refer to the applicable Service Manual for procedures on propeller shaft removal/installation. Towing Procedure In order to properly dinghy tow the vehicle, use the following procedure: 1. Firmly set the parking brake. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Towing Information > System Information > Technical Service Bulletins > Vehicle - Recreational (Dinghy) Towing Information > Page 15169 2. Place the AT in Park (P) or the MT in the lowest gear (1st). 3. Securely attach the vehicle being towed to the tow vehicle. Caution: Shifting the transfer case to Neutral can cause the vehicle to roll, even if the transmission is in park (automatic) or 1st gear (manual), and may cause personal injury. 4. If equipped, place the transfer case shift lever in Neutral (N). Note: Use extra care whenever towing another vehicle. Do not exceed the towing vehicle's gross combination weight (GCW) by adding the weight of the dinghy towed vehicle or vehicle damage may result. 5. When the vehicle being towed is firmly attached to the tow vehicle, release the parking brake. 6. The Owner's Manual specifies the appropriate ignition key position to ensure that the steering is unlocked to allow the front wheels to follow the tow vehicle. Rear Wheel Drive Light Duty Trucks Important: ^ Dust or dirt can enter the back of the transmission through the opening created by the removal of the slip yoke from the transmission if proper protection is not provided. ^ Verify that the transmission fluid is at the proper level before driving the truck. Rear wheel drive vehicles, equipped with AT or MT, should NOT be dinghy towed. These transmissions have no provisions for internal lubrication while being towed. In order to properly tow these vehicles, place the vehicle on a platform trailer with all four tires off the ground. Avoid towing the vehicle with all four tires on the ground. In rare instances when it is unavoidable that a rear wheel drive vehicle be dinghy towed, the propeller shaft to axle yoke orientation should be marked and the propeller shaft removed. Refer to the applicable Service Manual for procedures on propeller shaft removal/installation.

The draw may be steady or may drop down to a low milliamp reading for 1-2 seconds and then rise back up to the 4.1 amp range. If this amp draw condition is observed, check for aftermarket accessories or an improperly installed GM accessory that is wired into circuit 6815 (orange wire) for courtesy lamps. Anytime aftermarket accessories are installed into the courtesy lamp circuit, it can cause the inadvertent power timer in the body control module (BCM) to keep resetting. The BCM will remain awake and cause the draw of approximately 4.1 amps. When servicing a vehicle with this concern, back out pin 1 of the connector 2 at the BCM and see if the draw goes away. If the draw goes away, check for an aftermarket accessory (Lojack, non-factory DVD system, alarm, etc.) that is improperly installed in circuit 6815.

This new primer comes in several different colors from five different suppliers. This change affects the cleaning process of the painting operation. The new process is as follows. 1. Wash with soap and water. 2. Clean with a 50% mix of isopropyl alcohol and water (or a waterborne cleaner). Check with your paint supplier for product recommendations. 3. Scuff sand per your paint suppliers recommendations. Note: The use of a solvent-type cleaner will soften, or begin to dissolve the primer. Base coats do not have any affect on this primer. 4. Reclean with a 50% mix of isopropyl alcohol and water (or a waterborne cleaner). All fascias, with the exception of the Corvette, Camaro, and Cadillac XLR, are made of TPO. You may find other TPO parts with this primer. If the technician has a question as to the type of plastic they are painting, inspect the back of the part for the plastic symbol (TPO).

This new primer comes in several different colors from five different suppliers. This change affects the cleaning process of the painting operation. The new process is as follows. 1. Wash with soap and water. 2. Clean with a 50% mix of isopropyl alcohol and water (or a waterborne cleaner). Check with your paint supplier for product recommendations. 3. Scuff sand per your paint suppliers recommendations. Note: The use of a solvent-type cleaner will soften, or begin to dissolve the primer. Base coats do not have any affect on this primer. 4. Reclean with a 50% mix of isopropyl alcohol and water (or a waterborne cleaner). All fascias, with the exception of the Corvette, Camaro, and Cadillac XLR, are made of TPO. You may find other TPO parts with this primer. If the technician has a question as to the type of plastic they are painting, inspect the back of the part for the plastic symbol (TPO).

Please discard Corporate Bulletin Number 00-08-48-005C (Section 08 - Body and Accessories). Distortion in the outer surface of the windshield glass, door glass or backlite glass may appear after the vehicle has: - Accumulated some mileage. - Been frequently washed in automatic car washes, particularly "touchless" car washes. This distortion may look like a subtle orange peel pattern, or may look like a drip or sag etched into the surface of the glass. Some car wash solutions contain a buffered solution of hydrofluoric acid which is used to clean the glass. This should not cause a problem if used in the correct concentration. However, if not used correctly, hydrofluoric acid will attack the glass, and over time, will cause visual distortion in the outer surface of the glass which cannot be removed by scraping or polishing. If this condition is suspected, look at the area of the windshield under the wipers or below the belt seal on the side glass. The area of the glass below the wipers or belt seal will not be affected and what looks like a drip or sag may be apparent at the edge of the wiper or belt seal. You may also see a line on the glass where the wiper blade or the belt seal contacts the glass. Important The repair will require replacing the affected glass and is not a result of a defect in material or workmanship. Therefore, is not covered by New Vehicle Warranty.

Condition General Motors has decided that certain 2007 Chevrolet Equinox and Pontiac Torrent model vehicles fail to conform to Federal/Canada Motor Vehicle Safety Standard (MVSS) 212, Windshield Mounting. On some of these vehicles, an incorrect primer may have been used when installing the windshield. In the event of a crash, the windshield may not be retained to the extent required by the Standard, increasing the risk of personal injuries to the vehicle occupants. The same primer may have also been applied to the liftgate glass and the side stationary glass. Correction For vehicles in customer possession, export vehicles, certain vehicles located in remote areas, and inventory vehicles identified in the "Dealer Repaired Vehicles" report, dealers are to replace the windshield, liftgate glass, and the side stationary glass. A listing of vehicles to repair, titled "Dealer Repaired Vehicles", has been sent in the Administrative Message releasing this bulletin. For vehicles in dealer inventory (greater than one), dealers are to hold the vehicle. The General Motors Dealer Business Center will contact dealers to arrange for return of the vehicles to GM. The vehicle transport company that normally services the dealership will facilitate the vehicle pick up. The vehicles will then be inspected, repaired if necessary, and returned to dealers as quickly as possible. A listing of vehicles to be returned to GM, titled "Vehicles Returned to GM", has been sent in the Administrative Message releasing this bulletin. Each vehicle will be returned with a completed Inspection/Repair Worksheet in the vehicle. This document will clearly indicate if the vehicle passed or failed the inspection. Vehicles that pass require no further action and can be released for sale/delivery. Vehicles that fail the inspection will require replacement of the specific fixed glass noted on the worksheet. This could be the windshield only, or the windshield and right side rear quarter, or the liftgate and left side rear quarter. Once the discrepant glass is replaced, the vehicle can be released for sale/delivery.

On some of these vehicles, an incorrect primer may have been used when installing the windshield. In the event of a crash, the windshield may not be retained to the extent required by the Standard, increasing the risk of personal injuries to the vehicle occupants. The same primer may have also been applied to the liftgate glass and the side stationary glass. Correction For vehicles in customer possession, export vehicles, certain vehicles located in remote areas, and inventory vehicles identified in the "Dealer Repaired Vehicles" report, dealers are to replace the windshield, liftgate glass, and the side stationary glass. A listing of vehicles to repair, titled "Dealer Repaired Vehicles", has been sent in the Administrative Message releasing this bulletin. For vehicles in dealer inventory (greater than one), dealers are to hold the vehicle. The General Motors Dealer Business Center will contact dealers to arrange for return of the vehicles to GM. The vehicle transport company that normally services the dealership will facilitate the vehicle pick up. The vehicles will then be inspected, repaired if necessary, and returned to dealers as quickly as possible. A listing of vehicles to be returned to GM, titled "Vehicles Returned to GM", has been sent in the Administrative Message releasing this bulletin. Each vehicle will be returned with a completed Inspection/Repair Worksheet in the vehicle. This document will clearly indicate if the vehicle passed or failed the inspection. Vehicles that pass require no further action and can be released for sale/delivery. Vehicles that fail the inspection will require replacement of the specific fixed glass noted on the worksheet. This could be the windshield only, or the windshield and right side rear quarter, or the liftgate and left side rear quarter. Once the discrepant glass is replaced, the vehicle can be released for sale/delivery.

Please discard Corporate Bulletin Number 06-00-89-029E (Section 00 - General Information). To keep the vehicle interior looking the best, it should be cleaned often. It is important to keep the upholstery from becoming heavily soiled. The vehicle's interior can experience extreme heat, which can cause stains to set quickly. Lighter color interiors may require more frequent cleaning. Care should be taken because newspapers and garments may transfer color to the vehicle's interior. Many of today's interiors are made with new low gloss materials. Permanent damage may result from using cleaners on ANY surfaces (interior trim, instrument panel, carpet, leather, vinyl and fabric) for which they are not intended. Using non-approved products can actually set the stain to the point that nothing can remove it. Important Do not use silicone or wax-based products or those containing organic solvents (such as naptha, alcohol, etc.) to clean your vehicle's interior because they can alter the appearance by increasing the gloss in a non-uniform manner. The increase in gloss may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions. - Never use a STIFF brush or a brush that has been previously used with a harsh chemical. This can cause damage to the vehicle's interior surfaces. - Use only mild, Neutral-pH cleaners. Avoid laundry detergents or dishwashing soaps with degreasers. Using too much soap will leave residue that leaves streaks and attracts dirt. Because it is critical to use only mild, neutral-pH cleaners, General Motors has approved the use of the cleaners and conditioners listed in this bulletin for the cleaning of interiors. These products are in the neutral-pH range and will maintain the best vehicle interior appearance. These products are water-based, biodegradable, and do not contain bleach, solvents or harsh chemicals. Interior trim pieces on new vehicles, as well as service components, arrive with a protective film. When removing the protective film, adhesive residue may be left on the trim panels/components. The cleaner (for leather, vinyl, plastic and interior paint) is an effective cleaner in removing adhesive residue without causing damage to the component. Important - If soapy, alkaline cleaning solutions are used on fabrics, and not thoroughly rinsed out, the residual left in the fabric will attract dirt. Because the recommended cleaners/conditioners are in the pH neutral range, they won't leave behind soapy residue. - On heavily stained or difficult to clean fabric/carpet, it is recommended that the entire surface be treated and cleaned vs. spot cleaning. Refer to Extractor Machine and Concentrate section of this bulletin for more information. Effective cleaning steps for hard and/or plastic surfaces: 1. Using a clean towel, apply/spray cleaner - leather, vinyl, plastic, interior paint, directly onto the towel. 2. Wipe the surface with the towel/cleaner. 3. If necessary, use a soft bristle brush to work cleaner into the crevasses of the area being cleaned. 4. Wipe off any excess cleaner from the surface. 5. Using a clean towel, apply/spray the conditioner (leather, vinyl restorer) directly onto the towel. 6. Wipe the conditioner onto the previously cleaned area to restore the material to it's original luster. Important Today's interiors are developed and intended to have a low-gloss appearance. It is important to use only products which provide a low-gloss finish in order to maintain the interior's integrity, customer appeal and satisfaction. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Interior Moulding / Trim > Carpet > Component Information > Technical Service Bulletins > Interior - Cleaning Interior Surfaces of Vehicle > Page 15613 Effective cleaning steps for fabric: 1. Remove any residue by lightly rubbing the surface with a clean towel. 2. Choose the appropriate stain remover based on the stain type. 3. Spray and lightly brush the area with a clean, soft bristle brush. 4. Gently blot up the stain. 5. On upholstery/carpet, the use of a fabric protector can help to reduce or eliminate future staining. Upholstery and Carpet Stains When cleaning upholstery and carpet stains ONLY, the following cleaning chart will help you determine which cleaner/formula works best on a particular stain. The chart lists many of the common stains. Some complex stains may require the application of both stain removers, one after the other, to remove both food-based oils and synthetic oils. A soft bristle brush (P/N 88861425) should be used to safely work the cleaner into the leather grain or material. This enables the dirt/stain to be completely removed from the material. Leather Conditioner/Restorer A Leather Conditioner/Restorer is also available. The restorer is safe for all vinyl and leather. It is a water-based product and contains essential emollients to restore suppleness, conditions and adds luster without adding gloss. The restorer will also provide protection against re-staining.

The lighter the leather color, the more quickly the dye transfer will appear. Leather should be cleaned on a regular basis so that the dirt and grime do not adversely affect the top coat of the leather. After cleaning the leather, it is important to treat the surface with the restorer. Extractor Machine and Concentrate For difficult to clean materials or when cleaning a large area, the best results will be achieved when using an extractor machine and concentrate. General Motors offers the Ruby Extractor (P/N 627-CC-3000AU) through GM Tools and Equipment 1-800-GM-TOOLS, and has recently released a concentrate for use with the extractor machine. Whichever extractor machine is used, it should meet the minimum specifications of the Ruby Extractor: Ruby Extractor Specifications: - Pump PSI: 55 - Water Lift: 85" - Hose Length: 10 ft Important The Ruby Extractor also comes with a 6 year Outer Body and 3 year Parts warranty. Extractor: The Ruby Extractor machine was designed for automotive use and works effectively in the vehicle's interior. The narrow design of the vacuum head allows detail work in tight areas. The water pressure pump is reduced so the fabric surface is not wet more than is necessary. The dry time is greatly reduced due to less water on the fabric surface, the vacuum head making better contact with the surface and the significant water lift capability of the machine. Concentrate: The concentrated extraction cleaner is engineered with lower pH levels to help remove alkaline buildup on fabrics. The concentrate should be mixed according to the instructions listed on the container. The available concentrate helps to break the stain down and then the stain is easily removed with less water. The concentrate used in the Ruby Extractor is slightly acidic to remove soap and alkalinity from the fabric surfaces left behind by using improper, soapy solutions. Dirt, grease and grime are more easily removed when the proper solution is used during the extraction process. Parts Information Products are available in two sizes; 8 oz / 235 ML and 24 oz / 710 ML bottles. Available Equipment Equipment is available by contacting 1-800-GMTOOLS.

Vehicle Odor Elimination General Motors offers a product that may control or eliminate odors in the interior and luggage compartment areas of GM vehicles. GM Vehicle Care Odor Eliminator is a non-toxic, biodegradable odor remover. This odorless product has been shown to greatly reduce or remove objectionable smells of mold and mildew resulting from vehicle water leaks (as well as customer created odors, i.e. smoke). You may use GM Vehicle Care Odor Eliminator on fabrics, vinyl, leather, carpet and sound deadening materials. It may also be induced into HVAC modules and instrument panel ducts (for the control of non-bacterial related odors). Important: This product leaves no residual scent and should not be sold as or considered an air freshener. Product action may result in the permanent elimination of an odor and may be preferable to customers with allergies who are sensitive to perfumes. How to Use This Product GM Vehicle Care Odor Eliminator may be sprayed on in a ready-to-use formula or used in steam cleaners as an additive with carpet shampoo. This water-based, odorless product is safe for all vehicle interiors. Do not wet or soak any interior surface that plain water would cause to deteriorate, as this product will have the same effect. Also avoid letting this product come into contact with vinegar or any acidic substance. Acid-based products will hamper the effectiveness of, or render GM Vehicle Care Odor Eliminator inert. Note: Complete eight page treatment sheets are enclosed within each case of GM Vehicle Care Odor Eliminator. These treatment instructions range from simple vehicle odor elimination to full step by step procedures for odor removal from water leaks. If lost, contact 800-977-4145 to get a replacement set faxed or e-mailed to your dealership. Instructions and cautions are printed on the bottle, but additional help is available. If you encounter a difficult to eliminate or reoccurring odor, you may call 1-800-955-8591 (in Canada, 1-800-977-4145) to obtain additional information and usage suggestions. Important: This product may effectively remove odors when directly contacting the odor source. It should be used in conjunction with diagnostic procedures (in cases such as a water leak) to first eliminate the root cause of the odor, and then the residual odor to permanently correct the vehicle condition. Vehicle Waterleak Odor Elimination STEP ONE: Confirm that all water leaks have been repaired. Determine what areas of the vehicle were water soaked or wet. Components with visible mold/mildew staining should be replaced. Isolate the odor source inside the vehicle. Often an odor can be isolated to an area or component of the vehicle interior by careful evaluation. Odor evaluation may need to be performed by multiple persons. Another method of isolating an odor source is to remove and segregate interior trim and components. Plastic sheeting or drop cloths can be used to confine seats, headliners, etc. to assist in evaluation and diagnoses. If appropriate the vehicle and interior trim should be evaluated separately to determine if the odor stays with the vehicle or the interior components. Odors that stay with the vehicle may be isolated to insulating and sound deadening materials (i.e. water leak at the windshield or standing water in the front foot well area caused mold/mildew to form on the bulkhead or kick panel sound deadening pads. If the interior is removed the floor pan and primed/painted surfaces should be treated with bleach/soap solution, rinsed with clean water and dried. Interior surfaces should then be treated with GM Vehicle Care Odor Eliminator product before reinstalling carpet or reassembling. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Interior Moulding / Trim > Carpet > Component Information > Technical Service Bulletins > Interior - Cleaning Interior Surfaces of Vehicle > Page 15619 The GM Vehicle Care Odor Eliminator product is an effective odor elimination product when used properly. It must come into direct contact with the odor source. It should be used in conjunction with diagnostic procedures to first eliminate the root cause of the odor. Some procedures for use after odor root cause correction are: STEP TWO: ^ Use the trigger spray head. ^ Put a drop of dish soap the size of a quarter in the bottom of a bottle. ^ Add 8 oz. of GM Vehicle Care Odor Eliminator (1 cup) to the dish soap and top off the bottle with tap water. ^ This formula should be used on hard surfaces (dash, interior plastic molding, and floor pan) STEP THREE: The third step to neutralizing the vehicle is a light to medium treatment of all carpeting and upholstered seats with the GM Vehicle Care Odor Eliminator formula and a wide fan spray setting (at full strength) (i.e.: carpeting on the driver's side requires 4-5 triggers pulls for coverage). The headliner and trunk should be sprayed next. Lightly brushing the formula into the carpeting and upholstery is a recommended step for deep odor problems. The dash and all hard surfaces should be sprayed with dish soap/water mixture. Let stand for 1-2 minutes then wipe off the surface. STEP FOUR: (vehicle ventilation system treatment) The ventilation system is generally the last step in the treatment of the vehicle. a. Spray the GM Vehicle Care Odor Eliminator formula into all dash vents. (1-2 trigger pulls per vent). b. Start the vehicle and turn the vehicle fan on high cool (not A/C setting). c. Spray the formula (10 trigger pulls) into the outside fresh air intake vent (cowl at base of windshield) d. Enter the vehicle after 1 minute and wipe off the excess formula spurting out of the dash vents. e. Smell the air coming from the dash vents. If odors are still present, spray another 5 triggers into the cowl, wait another minute and smell the results. Once you have obtained a fresh, clean smell coming from the vents, turn the system to the A/C re-circulation setting. Roll up the windows, spray 3-5 pumps into the right lower IP area and let the vehicle run with the fan set on high for 5-7 minutes. Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. Additional Suggestions to Increase Customer Satisfaction Here are some additional ideas to benefit your dealership and to generate greater customer enthusiasm for this product. ^ Keep this product on-hand for both the Service Department and the Used Car lot. Add value to your used car trades; treat loaner and demo cars during service and at final sale to eliminate smoke, pet, and other common odors offensive to customers. Make deodorizing a vehicle part of your normal vehicle detailing service. ^ Consider including GM Vehicle Care Odor Eliminator as a give-away item with new vehicle purchases. Many dealers give away as "gifts" various cleaning supplies at time of delivery. GM Odor Eliminator is one of a few products GM offers that has as many uses in the home as in the vehicle. Customers may find this product can be used for a host of recreational activities associated with their new vehicle, such as deodorizing a boat they tow, or a camper. ^ GM Odor Eliminator and many of the GM Vehicle Care products offer you the chance to increase dealership traffic as these superior quality products cannot be purchased in stores. Many Dealerships have product displays at the parts counter. Consider additional displays in the Customer Service Lounge, the Showroom and at the Service Desk or Cashier Window. Many customers who purchase vehicles and receive regular maintenance at your dealership may never visit the parts counter, and subsequently are not exposed to the variety and value that these products offer.

There are parts of the SIR system installed in various locations around a vehicle. To find the location of the SIR components refer to SIR Identification Views. There are several reasons for disabling the SIR system, such as repairs to the SIR system or servicing a component near or attached to an SIR component. There are several ways to disable the SIR system depending on what type of service is being performed. The following information covers the proper procedures for disabling/enabling the SIR system. SIR Service Precautions Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Failure to observe the correct procedure could cause deployment of the SIR components. Serious injury can occur. Failure to observe the correct procedure could also result in unnecessary SIR system repairs. The inflatable restraint sensing and diagnostic module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the air bags if the SDM loses battery power during a collision. Deployment power is available for as much as 1 minute after disconnecting the vehicle power. Waiting 1 minute before working on the system after disabling the SIR system prevents deployment of the air bags from the reserved energy supply. General Service Instructions The following are general service instructions which must be followed in order to properly repair the vehicle and return it to its original integrity: * Do not expose inflator modules to temperatures above 65°C (150°F). * Verify the correct replacement part number. Do not substitute a component from a different vehicle. * Use only original GM replacement parts available from your authorized GM dealer. Do not use salvaged parts for repairs to the SIR system. Discard any of the following components if it has been dropped from a height of 91 cm (3 feet) or greater: * Inflatable restraint sensing and diagnostic module (SDM) * Any Inflatable restraint air bag module * Inflatable restraint steering wheel module coil * Any Inflatable restraint sensor * Inflatable restraint seat belt pretensioners * Inflatable restraint Passenger Presence System (PPS) module or sensor Disabling Procedure - Air Bag Fuse 1. Turn the steering wheel so that the vehicles wheels are pointing straight ahead. 2. Place the ignition in the OFF position. Important: The SDM may have more than one fused power input. To ensure there is no unwanted SIR deployment, personal injury, or unnecessary SIR system repairs, remove all fuses supplying power to the SDM. With all SDM fuses removed and the ignition switch in the ON position, the AIR BAG warning indicator illuminates. This is normal operation, and does not indicate a SIR system malfunction. 3. Locate and remove the fuse(s) supplying power to the SDM. 4. Wait 1 minute before working on the system. Enabling Procedure - Air Bag Fuse 1. Place the ignition in the OFF position.

Customer Notification General Motors will notify customers of this recall on their vehicle (see copy of customer letter shown in this bulletin). Dealer Recall Responsibility The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time. This bulletin is notice to you that the new motor vehicles included in this recall may not comply with the standard identified above. Under Title 49, Section 30112 of the United States Code, it is illegal for a dealer to sell a new motor vehicle which the dealer knows does not comply with an applicable Federal Motor Vehicle Safety Standard. As a consequence, if you sell any of these motor vehicles without first performing the recall correction, your dealership may be subject to a civil penalty for each such sale. All unsold new vehicles in dealers possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall bulletin before customers take possession of these vehicles. Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer.

For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through GM DealerWorld Recall Information. Dealers will not have a report available if they have no involved vehicles currently assigned. The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall. Parts Information Parts required to complete this recall are to be obtained from General Motors Service and Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order. Courtesy Transportation The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Interior Moulding / Trim > Headliner > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Headliner: > 07281A > May > 08 > Recall - Head Impact Noncompliance > Page 15703 and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines. Claim Information Submit a Product Recall Claim with the information shown above. Customer Notification General Motors will notify customers of this recall on their vehicle (see copy of customer letter shown in this bulletin). Dealer Recall Responsibility The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time. This bulletin is notice to you that the new motor vehicles included in this recall may not comply with the standard identified above. Under Title 49, Section 30112 of the United States Code, it is illegal for a dealer to sell a new motor vehicle which the dealer knows does not comply with an applicable Federal Motor Vehicle Safety Standard. As a consequence, if you sell any of these motor vehicles without first performing the recall correction, your dealership may be subject to a civil penalty for each such sale. All unsold new vehicles in dealers possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall bulletin before customers take possession of these vehicles. Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter is shown in this bulletin for your use in contacting customers. Recall follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter. In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your dealership for service in the future, you must take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.

Code Security Rules and Information INFORMATION Bulletin No.: 10-00-89-010 Date: May 27, 2010 Subject: Key Code Security Rules and Information on GM KeyCode Look-Up Application (Canada Only) Models: 2011 and Prior GM Passenger Cars and Trucks 2010 and Prior HUMMER H2, H3 2009 and Prior Saturn and Saab 2002 and Prior Isuzu Attention: This bulletin has been created to address potential issues and questions regarding KeyCode security. This bulletin should be read by all parties involved in KeyCode activity, including dealer operator, partner security coordinator, sales, service and parts departments. A copy of this bulletin should be printed and maintained in the parts department for use as a reference. Important U.S. dealers should refer to Corporate Bulletin Number 10-00-89-009. Where Are Key Codes Located? General Motors provides access to KeyCodes through three sources when a vehicle is delivered to a dealer. Vehicle KeyCodes are located on the original vehicle invoice to the dealership. There is a small white bar coded tag sent with most new vehicles that also has the key code printed on it. Dealerships should make a practice of comparing the tag's keycode numbers to the keycode listed on the invoice. Any discrepancy should be reported immediately to the GM of Canada Key Code Inquiry Desk. Remember to remove the key tag prior to showing vehicles to potential customers. The third source for Key codes is through the GM KeyCode Look-Up feature within the OEConnection D2DLink application. KeyCode Look-Up currently goes back 17 previous model years from the current model year. When a vehicle is received by the dealership, care should be taken to safeguard the original vehicle invoice and KeyCode tag provided with the vehicle. Potential customers should not have access to the invoice or this KeyCode tag prior to the sale being completed. After a sale has been completed, the KeyCode information belongs to the customer and General Motors. Tip Only the original invoice contains key code information, a re-printed invoice does not. GM KeyCode Look-Up Application for GM of Canada Dealers All dealers should review the General Motors of Canada KeyCode Look-Up Policies and Procedures (Service Policy & Procedures Manual Section 3.1.6 "Replacement of VIN plates & keys"). Please note that the KeyCode Access site is restricted. Only authorized users should be using this application. Please see your Parts Manager for site authorized users. KeyCode Look-Up currently goes back 17 years from current model year. Important notes about security: - Users may not access the system from multiple computers simultaneously. - Users may only request one KeyCode at a time. - KeyCode information will only be available on the screen for 2 minutes. - Each user is personally responsible for maintaining and protecting their password. - Never share your password with others. - User Id's are suspended after 6 consecutive failed attempts. - User Id's are disabled if not used for 90 days. - Processes must be in place for regular dealership reviews. - The Parts Manager (or assigned management) must have processes in place for employee termination or life change events. Upon termination individuals access must be turned off immediately and access should be re-evaluated upon any position changes within the dealership. - If you think your password or ID security has been breached, contact Dealer Systems Support at 1-800-265-0573. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Locks > Key > Component Information > Technical Service Bulletins > Locks - Key Code Security Rules and Information > Page 15744 Each user will be required to accept the following agreement each time the KeyCode application is used. Key Code User Agreement - Key codes are proprietary information belonging to General Motors Corporation and to the vehicle owner. - Unauthorized access to, or use of, key code information is unlawful and may subject the user to criminal and civil penalties. - This information should be treated as strictly confidential and should not be disclosed to anyone unless authorized. I will ensure that the following information is obtained prior to releasing any Key Code information: 1. Government issued picture ID (Drivers License) 2. Registration or other proof of ownership. Registration should have normal markings from the Province that issued the registration and possibly the receipt for payment recorded as well. Important - GM takes this agreement seriously. Each user must be certain of vehicle ownership before giving out key codes. - When the ownership of the vehicle is in doubt, dealership personnel should not provide the information. Key code requests should never be received via a fax or the internet and key codes should never be provided to anyone in this manner. A face to face contact with the owner of the vehicle is the expected manner that dealers will use to release a key code or as otherwise stipulated in this bulletin or other materials. - Key codes should NEVER be sent via a fax or the internet. - Each Dealership should create a permanent file to document all KeyCode Look Up transactions. Requests should be filed by VIN and in each folder retain copies of the following: - Government issued picture ID (Drivers License) - Registration or other proof of ownership. - Copy of the paid customer receipt which has the name of the employee who cut and sold the key to the customer. - Do not put yourself or your Dealership in the position of needing to "explain" a KeyCode Look Up to either GM or law enforcement officials. - Dealership Management has the ability to review all KeyCode Look-Up transactions. - Dealership KeyCode documentation must be retained for two years. Frequently Asked Questions (FAQs) for GM of Canada Dealers How do I request a KeyCode for customer owned vehicle that is not registered? Scrapped, salvaged or stored vehicles that do not have a current registration should still have the ownership verified by requesting the vehicle title, current insurance policy and / or current lien holder information from the customers financing source. If you cannot determine if the customer is the owner of the vehicle, do not provide the key code information. In these cases, a short description of the vehicle (scrapped, salvaged, etc.) and the dealership location should be kept on file. Any clarifying explanation should be entered into the comments field. How do I document a KeyCode request for a vehicle that is being repossessed? The repossessor must document ownership of the vehicle by providing a court ordered repossession order and lien-holder documents prior to providing key code information. Copies of the repossessors Drivers License and a business card should be retained by the dealership for documentation. What do I do if the registration information is locked in the vehicle? Every effort should be made to obtain complete information for each request. Each Dealership will have to decide on a case by case basis if enough information is available to verify the customer's ownership of the vehicle. Other forms of documentation include vehicle title, insurance policy, and or current lien information from the customers financing source. Dealership Management must be involved in any request without complete information. If you cannot determine if the customer is the owner of the vehicle, do not provide the key code information. Can I get a print out of the information on the screen? It is important to note that the Key Code Look Up Search Results contain sensitive and/or proprietary information. For this reason GM recommends against printing it. If the Search Results must be printed, store and/or dispose of the printed copy properly to minimize the risk of improper or illegal use. Who in the dealership has access to the KeyCode application? Dealership Parts Manager (or assigned management) will determine, and control, who is authorized to access the KeyCode Look Up application. However, we anticipate that dealership parts and service management will be the primary users of the application. The KeyCode Look Up application automatically tracks each user activity session. Information tracked by the system includes: User name, User ID, all other entered data and the date/time of access. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Locks > Key > Component Information > Technical Service Bulletins > Locks - Key Code Security Rules and Information > Page 15745 What if I input the VIN incorrectly? If an incorrect VIN is entered into the system (meaning that the system does not recognize the VIN or that the VIN has been entered incorrectly) the system will return an error message. If I am an authorized user for the KeyCode application, can I access the application from home? Yes. What if I suspect key code misuse? Your dealership should communicate the proper procedures for requesting key codes. Any suspicious activity either within the dealership or externally should be reported to Dealer Systems Support at 1-800-265-0573 or GM of Canada Key Code Inquiry Desk at 1-905-644-4892. Whose key codes can I access through the system? At this time the following Canadian vehicle codes are available through the system: Chevrolet, Cadillac, Buick, Pontiac, GMC, HUMMER (H2 and H3 only), Oldsmobile, Saturn, Saab and Isuzu (up to 2002 model year) for a maximum of 17 model years. What should I do if I enter a valid VIN and the system does not produce any key code information? Occasionally, the KeyCode Look Up application may not produce a key code for a valid VIN. This may be the result of new vehicle information not yet available. In addition, older vehicle information may have been sent to an archive status. If you do not receive a key code returned for valid VIN, you should contact GM of Canada Key Code Inquiry Desk at 1-905-644-4892. How do I access KeyCodes if the KeyCode Look-up system is down? If the KeyCode Look-up system is temporarily unavailable, you can contact the original selling dealer who may have it on file or contact GM of Canada Key Code Inquiry Desk at 1-905-644-4892. If the customer is dealing with an emergency lock-out situation, you need to have the customer contact Roadside assistance, OnStar if subscribed, or 911. What should I do if the KeyCode from the look-up system does not work on the vehicle? On occasion a dealer may encounter a KeyCode that will not work on the vehicle in question. In cases where the KeyCode won't work you will need to verify with the manufacturer of the cutting equipment that the key has been cut correctly. If the key has been cut correctly you may be able to verify the proper KeyCode was given through the original selling dealer. When unable to verify the KeyCode through the original selling dealer contact GM of Canada Key Code Inquiry Desk at 1-905-644-4892. If the key has been cut correctly and the code given does not work, the lock cylinder may have been changed. In these situations following the proper SI document for recoding a key or replacing the lock cylinder may be necessary. How long do I have to keep KeyCode Records? Dealership KeyCode documentation must be retained for two years. Can I get a KeyCode changed in the Look-Up system? Yes, KeyCodes can be changed in the Look-Up system if a lock cylinder has been changed. Contact GM of Canada Key Code Inquiry Desk at 1-905-644-4892. What information do I need before I can provide a driver of a company fleet vehicle Keys or KeyCode information? The dealership should have a copy of the individual's driver's license, proof of employment and registration. If there is any question as to the customer's employment by the fleet company, the dealer should attempt to contact the fleet company for verification. If there is not enough information to determine ownership and employment, this information should not be provided. How do I document a request from an Independent Repair facility for a KeyCode or Key? The independent must provide a copy of their driver's license, proof of employment and signed copy of the repair order for that repair facility. The repair order must include customer's name, address, VIN, city, province and license plate number. Copies of this information must be included in your dealer KeyCode file.

Please discard Corporate Bulletin Number 08-08-64-011 (Section 08 - Body and Accessories). Defrosting Time/Performance Concern The electrochromatic (auto-dimming) outside rearview mirror used on the driver's side of many GM vehicles is slower to defrost than the passenger side outside rearview mirror. This is a normal condition. The glass on the driver's side electrochromatic mirror is twice as thick as the traditional glass on the passenger side mirror. The heating elements for the mirrors on both sides draw the same wattage, therefore the driver's side mirror will take approximately twice as long to defrost as the passenger mirror (approximately four minutes versus two minutes). Should a customer indicate that the driver's side heated mirror is not functioning correctly, verify it's function based upon this information prior to replacing the mirror.

Please discard Corporate Bulletin Number 05-08-51-008B (Section 08 - Body and Accessories). Condition Visible rust colored spots or bumps on a vehicle's paint surface from rail or iron dust. Cause Rail dust comes from tiny iron particles produced from the friction between train wheels and the tracks and gets deposited on the vehicle surfaces. Iron dust can get deposited on the surface if the vehicle is stored near any operation producing iron dust such as an iron ore yard. Either material can lay on top of, or become embedded in, the paint surface. Correction Because the severity of the condition varies, proper diagnosis of the damage is critical to the success of repairs. Diagnosis should be performed on horizontal surfaces (hood, roof, deck lid, pick up box, etc.) after the vehicle has been properly cleaned. There are two types of repair materials recommended to repair rail dust or iron dust: 1. GEL TYPE OXALIC ACID: - Has the characteristics of the liquid type oxalic acid but stays where you put it because of its gel consistency. 2. CLAY TYPE NON-ACID BASED: - Requires surface lubricant during use. - Has different grades available. Caution Rail dust remover (Oxalic Acid) is an acidic substance containing chemicals that will break down the iron particles embedded in the finish. When working with rail dust remover, use the necessary safety equipment, including gloves and goggles. Follow the chemical manufacturer's directions closely because it may require special handling and disposal. If, upon inspection, some particles are still present, the various chemical manufacturer's processes can be repeated. After the removal process, small pits may remain in the clearcoat and can be corrected, in most cases, with a finesse/polish operation. Procedure 1. Move the vehicle to a cool shaded area and make sure that the vehicle surfaces are cool during the removal process. DO NOT PERFORM THE REMOVAL PROCESS IN DIRECT SUNLIGHT OR ON A VEHICLE WITH HOT OR WARM BODY PANELS. 2. Wash the vehicle with soap and water. Dry it immediately and clean the affected areas with a wax and grease remover. 3. Perform the removal process according to the chemical manufacturer's directions. Once the damage has been repaired, the final step involves a polishing process.

Please discard Corporate Bulletin Number 05-08-51-008B (Section 08 - Body and Accessories). Condition Visible rust colored spots or bumps on a vehicle's paint surface from rail or iron dust. Cause Rail dust comes from tiny iron particles produced from the friction between train wheels and the tracks and gets deposited on the vehicle surfaces. Iron dust can get deposited on the surface if the vehicle is stored near any operation producing iron dust such as an iron ore yard. Either material can lay on top of, or become embedded in, the paint surface. Correction Because the severity of the condition varies, proper diagnosis of the damage is critical to the success of repairs. Diagnosis should be performed on horizontal surfaces (hood, roof, deck lid, pick up box, etc.) after the vehicle has been properly cleaned. There are two types of repair materials recommended to repair rail dust or iron dust: 1. GEL TYPE OXALIC ACID: - Has the characteristics of the liquid type oxalic acid but stays where you put it because of its gel consistency. 2. CLAY TYPE NON-ACID BASED: - Requires surface lubricant during use. - Has different grades available. Caution Rail dust remover (Oxalic Acid) is an acidic substance containing chemicals that will break down the iron particles embedded in the finish. When working with rail dust remover, use the necessary safety equipment, including gloves and goggles. Follow the chemical manufacturer's directions closely because it may require special handling and disposal. If, upon inspection, some particles are still present, the various chemical manufacturer's processes can be repeated. After the removal process, small pits may remain in the clearcoat and can be corrected, in most cases, with a finesse/polish operation. Procedure 1. Move the vehicle to a cool shaded area and make sure that the vehicle surfaces are cool during the removal process. DO NOT PERFORM THE REMOVAL PROCESS IN DIRECT SUNLIGHT OR ON A VEHICLE WITH HOT OR WARM BODY PANELS. 2. Wash the vehicle with soap and water. Dry it immediately and clean the affected areas with a wax and grease remover. 3. Perform the removal process according to the chemical manufacturer's directions. Once the damage has been repaired, the final step involves a polishing process.

Vehicles in inventory should be programmed during off peak hours if low performance is experienced. Important: This bulletin contains two reprogramming procedures, 1) reprogramming of the BCM, and 2) reprogramming of the RCDLR. Not all vehicles require reprogramming of both. ^ The Cadillac Escalade, Escalade ESV, Escalade EXT; Chevrolet Avalanche, Suburban, Tahoe; and GMC Yukon and Yukon XL vehicles require the BCM and RCDLR reprogramming. ^ The Buick Lucerne; Cadillac DTS; Chevrolet Impala, Monte Carlo; Chevrolet Equinox; and Pontiac Torrent require only the RCDLR reprogramming - DO NOT ATTEMPT TO REPROGRAM THE BCM ON THESE VEHICLES. Body Control Module Reprogramming - For Cadillac Escalade, Escalade ESV, Escalade EXT; Chevrolet Avalanche, Suburban, Tahoe; and GMC Yukon, Yukon XL ONLY: Important: The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2(R) scan tool and the Techline Information System (TIS) terminal with the calibration update. Use TIS 2 Web version 2.0 for 2007 (available on 02/04/07) and on TIS DVD version 2.0/2007 or later, that was mailed to dealers on 02/14/2007. If you cannot access the calibration, call the Techline Customer Support Center. Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use jumper cables from an additional battery. Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed. The ignition switch must be in the proper position. The Tech 2(R) prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.

Please discard all copies of bulletin 07287, issued May 2008. THIS PROGRAM IS IN EFFECT UNTIL MAY 31, 2009. Condition 2007 model year Chevrolet Equinox and Pontiac Torrent vehicles built without a head-curtain side impact air bag or without a sunroof not only meet but exceed government standards for head impact protection. GM has recently made changes that add to that protection. GM is making similar changes to vehicles built before this change was implemented. Correction To enhance head impact protection dealers are to install an energy-absorbing device on the driver and passenger side headliner. Vehicles Involved Involved are certain 2007 model year Chevrolet Equinox and Pontiac Torrent vehicles built without a head-curtain side impact air bag or without a sunroof and built within the VIN breakpoints shown above. Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the GM Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may be involved. For dealers with involved vehicles a listing with involved vehicles containing the complete vehicle identification number customer name and address information has been prepared and will be provided through GM DealerWorld Recall Information. Dealers will not have a report available if they have no involved vehicles currently assigned. The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly you are urged to limit the use of this report to the follow-up necessary to complete this recall.

Please discard Corporate Bulletin Number 06-00-89-029E (Section 00 - General Information). To keep the vehicle interior looking the best, it should be cleaned often. It is important to keep the upholstery from becoming heavily soiled. The vehicle's interior can experience extreme heat, which can cause stains to set quickly. Lighter color interiors may require more frequent cleaning. Care should be taken because newspapers and garments may transfer color to the vehicle's interior. Many of today's interiors are made with new low gloss materials. Permanent damage may result from using cleaners on ANY surfaces (interior trim, instrument panel, carpet, leather, vinyl and fabric) for which they are not intended. Using non-approved products can actually set the stain to the point that nothing can remove it. Important Do not use silicone or wax-based products or those containing organic solvents (such as naptha, alcohol, etc.) to clean your vehicle's interior because they can alter the appearance by increasing the gloss in a non-uniform manner. The increase in gloss may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions. - Never use a STIFF brush or a brush that has been previously used with a harsh chemical. This can cause damage to the vehicle's interior surfaces. - Use only mild, Neutral-pH cleaners. Avoid laundry detergents or dishwashing soaps with degreasers. Using too much soap will leave residue that leaves streaks and attracts dirt. Because it is critical to use only mild, neutral-pH cleaners, General Motors has approved the use of the cleaners and conditioners listed in this bulletin for the cleaning of interiors. These products are in the neutral-pH range and will maintain the best vehicle interior appearance. These products are water-based, biodegradable, and do not contain bleach, solvents or harsh chemicals. Interior trim pieces on new vehicles, as well as service components, arrive with a protective film. When removing the protective film, adhesive residue may be left on the trim panels/components. The cleaner (for leather, vinyl, plastic and interior paint) is an effective cleaner in removing adhesive residue without causing damage to the component. Important - If soapy, alkaline cleaning solutions are used on fabrics, and not thoroughly rinsed out, the residual left in the fabric will attract dirt. Because the recommended cleaners/conditioners are in the pH neutral range, they won't leave behind soapy residue. - On heavily stained or difficult to clean fabric/carpet, it is recommended that the entire surface be treated and cleaned vs. spot cleaning. Refer to Extractor Machine and Concentrate section of this bulletin for more information. Effective cleaning steps for hard and/or plastic surfaces: 1. Using a clean towel, apply/spray cleaner - leather, vinyl, plastic, interior paint, directly onto the towel. 2. Wipe the surface with the towel/cleaner. 3. If necessary, use a soft bristle brush to work cleaner into the crevasses of the area being cleaned. 4. Wipe off any excess cleaner from the surface. 5. Using a clean towel, apply/spray the conditioner (leather, vinyl restorer) directly onto the towel. 6. Wipe the conditioner onto the previously cleaned area to restore the material to it's original luster. Important Today's interiors are developed and intended to have a low-gloss appearance. It is important to use only products which provide a low-gloss finish in order to maintain the interior's integrity, customer appeal and satisfaction.

Remove any residue by lightly rubbing the surface with a clean towel. 2. Choose the appropriate stain remover based on the stain type. 3. Spray and lightly brush the area with a clean, soft bristle brush. 4. Gently blot up the stain. 5. On upholstery/carpet, the use of a fabric protector can help to reduce or eliminate future staining. Upholstery and Carpet Stains When cleaning upholstery and carpet stains ONLY, the following cleaning chart will help you determine which cleaner/formula works best on a particular stain. The chart lists many of the common stains. Some complex stains may require the application of both stain removers, one after the other, to remove both food-based oils and synthetic oils. A soft bristle brush (P/N 88861425) should be used to safely work the cleaner into the leather grain or material. This enables the dirt/stain to be completely removed from the material. Leather Conditioner/Restorer A Leather Conditioner/Restorer is also available. The restorer is safe for all vinyl and leather. It is a water-based product and contains essential emollients to restore suppleness, conditions and adds luster without adding gloss. The restorer will also provide protection against re-staining.

The lighter the leather color, the more quickly the dye transfer will appear. Leather should be cleaned on a regular basis so that the dirt and grime do not adversely affect the top coat of the leather. After cleaning the leather, it is important to treat the surface with the restorer. Extractor Machine and Concentrate For difficult to clean materials or when cleaning a large area, the best results will be achieved when using an extractor machine and concentrate. General Motors offers the Ruby Extractor (P/N 627-CC-3000AU) through GM Tools and Equipment 1-800-GM-TOOLS, and has recently released a concentrate for use with the extractor machine. Whichever extractor machine is used, it should meet the minimum specifications of the Ruby Extractor: Ruby Extractor Specifications: - Pump PSI: 55 - Water Lift: 85" - Hose Length: 10 ft Important The Ruby Extractor also comes with a 6 year Outer Body and 3 year Parts warranty. Extractor: The Ruby Extractor machine was designed for automotive use and works effectively in the vehicle's interior. The narrow design of the vacuum head allows detail work in tight areas. The water pressure pump is reduced so the fabric surface is not wet more than is necessary. The dry time is greatly reduced due to less water on the fabric surface, the vacuum head making better contact with the surface and the significant water lift capability of the machine. Concentrate: The concentrated extraction cleaner is engineered with lower pH levels to help remove alkaline buildup on fabrics. The concentrate should be mixed according to the instructions listed on the container. The available concentrate helps to break the stain down and then the stain is easily removed with less water. The concentrate used in the Ruby Extractor is slightly acidic to remove soap and alkalinity from the fabric surfaces left behind by using improper, soapy solutions. Dirt, grease and grime are more easily removed when the proper solution is used during the extraction process. Parts Information Products are available in two sizes; 8 oz / 235 ML and 24 oz / 710 ML bottles. Available Equipment Equipment is available by contacting 1-800-GMTOOLS.

Vehicle Odor Elimination General Motors offers a product that may control or eliminate odors in the interior and luggage compartment areas of GM vehicles. GM Vehicle Care Odor Eliminator is a non-toxic, biodegradable odor remover. This odorless product has been shown to greatly reduce or remove objectionable smells of mold and mildew resulting from vehicle water leaks (as well as customer created odors, i.e. smoke). You may use GM Vehicle Care Odor Eliminator on fabrics, vinyl, leather, carpet and sound deadening materials. It may also be induced into HVAC modules and instrument panel ducts (for the control of non-bacterial related odors). Important: This product leaves no residual scent and should not be sold as or considered an air freshener. Product action may result in the permanent elimination of an odor and may be preferable to customers with allergies who are sensitive to perfumes. How to Use This Product GM Vehicle Care Odor Eliminator may be sprayed on in a ready-to-use formula or used in steam cleaners as an additive with carpet shampoo. This water-based, odorless product is safe for all vehicle interiors. Do not wet or soak any interior surface that plain water would cause to deteriorate, as this product will have the same effect. Also avoid letting this product come into contact with vinegar or any acidic substance. Acid-based products will hamper the effectiveness of, or render GM Vehicle Care Odor Eliminator inert. Note: Complete eight page treatment sheets are enclosed within each case of GM Vehicle Care Odor Eliminator. These treatment instructions range from simple vehicle odor elimination to full step by step procedures for odor removal from water leaks. If lost, contact 800-977-4145 to get a replacement set faxed or e-mailed to your dealership. Instructions and cautions are printed on the bottle, but additional help is available. If you encounter a difficult to eliminate or reoccurring odor, you may call 1-800-955-8591 (in Canada, 1-800-977-4145) to obtain additional information and usage suggestions. Important: This product may effectively remove odors when directly contacting the odor source. It should be used in conjunction with diagnostic procedures (in cases such as a water leak) to first eliminate the root cause of the odor, and then the residual odor to permanently correct the vehicle condition. Vehicle Waterleak Odor Elimination STEP ONE: Confirm that all water leaks have been repaired. Determine what areas of the vehicle were water soaked or wet. Components with visible mold/mildew staining should be replaced. Isolate the odor source inside the vehicle. Often an odor can be isolated to an area or component of the vehicle interior by careful evaluation. Odor evaluation may need to be performed by multiple persons. Another method of isolating an odor source is to remove and segregate interior trim and components. Plastic sheeting or drop cloths can be used to confine seats, headliners, etc. to assist in evaluation and diagnoses. If appropriate the vehicle and interior trim should be evaluated separately to determine if the odor stays with the vehicle or the interior components. Odors that stay with the vehicle may be isolated to insulating and sound deadening materials (i.e. water leak at the windshield or standing water in the front foot well area caused mold/mildew to form on the bulkhead or kick panel sound deadening pads. If the interior is removed the floor pan and primed/painted surfaces should be treated with bleach/soap solution, rinsed with clean water and dried. Interior surfaces should then be treated with GM Vehicle Care Odor Eliminator product before reinstalling carpet or reassembling.

It must come into direct contact with the odor source. It should be used in conjunction with diagnostic procedures to first eliminate the root cause of the odor. Some procedures for use after odor root cause correction are: STEP TWO: ^ Use the trigger spray head. ^ Put a drop of dish soap the size of a quarter in the bottom of a bottle. ^ Add 8 oz. of GM Vehicle Care Odor Eliminator (1 cup) to the dish soap and top off the bottle with tap water. ^ This formula should be used on hard surfaces (dash, interior plastic molding, and floor pan) STEP THREE: The third step to neutralizing the vehicle is a light to medium treatment of all carpeting and upholstered seats with the GM Vehicle Care Odor Eliminator formula and a wide fan spray setting (at full strength) (i.e.: carpeting on the driver's side requires 4-5 triggers pulls for coverage). The headliner and trunk should be sprayed next. Lightly brushing the formula into the carpeting and upholstery is a recommended step for deep odor problems. The dash and all hard surfaces should be sprayed with dish soap/water mixture. Let stand for 1-2 minutes then wipe off the surface. STEP FOUR: (vehicle ventilation system treatment) The ventilation system is generally the last step in the treatment of the vehicle. a. Spray the GM Vehicle Care Odor Eliminator formula into all dash vents. (1-2 trigger pulls per vent). b. Start the vehicle and turn the vehicle fan on high cool (not A/C setting). c. Spray the formula (10 trigger pulls) into the outside fresh air intake vent (cowl at base of windshield) d. Enter the vehicle after 1 minute and wipe off the excess formula spurting out of the dash vents. e. Smell the air coming from the dash vents. If odors are still present, spray another 5 triggers into the cowl, wait another minute and smell the results. Once you have obtained a fresh, clean smell coming from the vents, turn the system to the A/C re-circulation setting. Roll up the windows, spray 3-5 pumps into the right lower IP area and let the vehicle run with the fan set on high for 5-7 minutes. Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. Additional Suggestions to Increase Customer Satisfaction Here are some additional ideas to benefit your dealership and to generate greater customer enthusiasm for this product. ^ Keep this product on-hand for both the Service Department and the Used Car lot. Add value to your used car trades; treat loaner and demo cars during service and at final sale to eliminate smoke, pet, and other common odors offensive to customers. Make deodorizing a vehicle part of your normal vehicle detailing service. ^ Consider including GM Vehicle Care Odor Eliminator as a give-away item with new vehicle purchases. Many dealers give away as "gifts" various cleaning supplies at time of delivery. GM Odor Eliminator is one of a few products GM offers that has as many uses in the home as in the vehicle. Customers may find this product can be used for a host of recreational activities associated with their new vehicle, such as deodorizing a boat they tow, or a camper. ^ GM Odor Eliminator and many of the GM Vehicle Care products offer you the chance to increase dealership traffic as these superior quality products cannot be purchased in stores. Many Dealerships have product displays at the parts counter. Consider additional displays in the Customer Service Lounge, the Showroom and at the Service Desk or Cashier Window. Many customers who purchase vehicles and receive regular maintenance at your dealership may never visit the parts counter, and subsequently are not exposed to the variety and value that these products offer.

Please discard Corporate Bulletin Number 06-00-89-029E (Section 00 - General Information). To keep the vehicle interior looking the best, it should be cleaned often. It is important to keep the upholstery from becoming heavily soiled. The vehicle's interior can experience extreme heat, which can cause stains to set quickly. Lighter color interiors may require more frequent cleaning. Care should be taken because newspapers and garments may transfer color to the vehicle's interior. Many of today's interiors are made with new low gloss materials. Permanent damage may result from using cleaners on ANY surfaces (interior trim, instrument panel, carpet, leather, vinyl and fabric) for which they are not intended. Using non-approved products can actually set the stain to the point that nothing can remove it. Important Do not use silicone or wax-based products or those containing organic solvents (such as naptha, alcohol, etc.) to clean your vehicle's interior because they can alter the appearance by increasing the gloss in a non-uniform manner. The increase in gloss may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions. - Never use a STIFF brush or a brush that has been previously used with a harsh chemical. This can cause damage to the vehicle's interior surfaces. - Use only mild, Neutral-pH cleaners. Avoid laundry detergents or dishwashing soaps with degreasers. Using too much soap will leave residue that leaves streaks and attracts dirt. Because it is critical to use only mild, neutral-pH cleaners, General Motors has approved the use of the cleaners and conditioners listed in this bulletin for the cleaning of interiors. These products are in the neutral-pH range and will maintain the best vehicle interior appearance. These products are water-based, biodegradable, and do not contain bleach, solvents or harsh chemicals. Interior trim pieces on new vehicles, as well as service components, arrive with a protective film. When removing the protective film, adhesive residue may be left on the trim panels/components. The cleaner (for leather, vinyl, plastic and interior paint) is an effective cleaner in removing adhesive residue without causing damage to the component. Important - If soapy, alkaline cleaning solutions are used on fabrics, and not thoroughly rinsed out, the residual left in the fabric will attract dirt. Because the recommended cleaners/conditioners are in the pH neutral range, they won't leave behind soapy residue. - On heavily stained or difficult to clean fabric/carpet, it is recommended that the entire surface be treated and cleaned vs. spot cleaning. Refer to Extractor Machine and Concentrate section of this bulletin for more information. Effective cleaning steps for hard and/or plastic surfaces: 1. Using a clean towel, apply/spray cleaner - leather, vinyl, plastic, interior paint, directly onto the towel. 2. Wipe the surface with the towel/cleaner. 3. If necessary, use a soft bristle brush to work cleaner into the crevasses of the area being cleaned. 4. Wipe off any excess cleaner from the surface. 5. Using a clean towel, apply/spray the conditioner (leather, vinyl restorer) directly onto the towel. 6. Wipe the conditioner onto the previously cleaned area to restore the material to it's original luster. Important Today's interiors are developed and intended to have a low-gloss appearance. It is important to use only products which provide a low-gloss finish in order to maintain the interior's integrity, customer appeal and satisfaction.

Remove any residue by lightly rubbing the surface with a clean towel. 2. Choose the appropriate stain remover based on the stain type. 3. Spray and lightly brush the area with a clean, soft bristle brush. 4. Gently blot up the stain. 5. On upholstery/carpet, the use of a fabric protector can help to reduce or eliminate future staining. Upholstery and Carpet Stains When cleaning upholstery and carpet stains ONLY, the following cleaning chart will help you determine which cleaner/formula works best on a particular stain. The chart lists many of the common stains. Some complex stains may require the application of both stain removers, one after the other, to remove both food-based oils and synthetic oils. A soft bristle brush (P/N 88861425) should be used to safely work the cleaner into the leather grain or material. This enables the dirt/stain to be completely removed from the material. Leather Conditioner/Restorer A Leather Conditioner/Restorer is also available. The restorer is safe for all vinyl and leather. It is a water-based product and contains essential emollients to restore suppleness, conditions and adds luster without adding gloss. The restorer will also provide protection against re-staining.

The lighter the leather color, the more quickly the dye transfer will appear. Leather should be cleaned on a regular basis so that the dirt and grime do not adversely affect the top coat of the leather. After cleaning the leather, it is important to treat the surface with the restorer. Extractor Machine and Concentrate For difficult to clean materials or when cleaning a large area, the best results will be achieved when using an extractor machine and concentrate. General Motors offers the Ruby Extractor (P/N 627-CC-3000AU) through GM Tools and Equipment 1-800-GM-TOOLS, and has recently released a concentrate for use with the extractor machine. Whichever extractor machine is used, it should meet the minimum specifications of the Ruby Extractor: Ruby Extractor Specifications: - Pump PSI: 55 - Water Lift: 85" - Hose Length: 10 ft Important The Ruby Extractor also comes with a 6 year Outer Body and 3 year Parts warranty. Extractor: The Ruby Extractor machine was designed for automotive use and works effectively in the vehicle's interior. The narrow design of the vacuum head allows detail work in tight areas. The water pressure pump is reduced so the fabric surface is not wet more than is necessary. The dry time is greatly reduced due to less water on the fabric surface, the vacuum head making better contact with the surface and the significant water lift capability of the machine. Concentrate: The concentrated extraction cleaner is engineered with lower pH levels to help remove alkaline buildup on fabrics. The concentrate should be mixed according to the instructions listed on the container. The available concentrate helps to break the stain down and then the stain is easily removed with less water. The concentrate used in the Ruby Extractor is slightly acidic to remove soap and alkalinity from the fabric surfaces left behind by using improper, soapy solutions. Dirt, grease and grime are more easily removed when the proper solution is used during the extraction process. Parts Information Products are available in two sizes; 8 oz / 235 ML and 24 oz / 710 ML bottles. Available Equipment Equipment is available by contacting 1-800-GMTOOLS.

Vehicle Odor Elimination General Motors offers a product that may control or eliminate odors in the interior and luggage compartment areas of GM vehicles. GM Vehicle Care Odor Eliminator is a non-toxic, biodegradable odor remover. This odorless product has been shown to greatly reduce or remove objectionable smells of mold and mildew resulting from vehicle water leaks (as well as customer created odors, i.e. smoke). You may use GM Vehicle Care Odor Eliminator on fabrics, vinyl, leather, carpet and sound deadening materials. It may also be induced into HVAC modules and instrument panel ducts (for the control of non-bacterial related odors). Important: This product leaves no residual scent and should not be sold as or considered an air freshener. Product action may result in the permanent elimination of an odor and may be preferable to customers with allergies who are sensitive to perfumes. How to Use This Product GM Vehicle Care Odor Eliminator may be sprayed on in a ready-to-use formula or used in steam cleaners as an additive with carpet shampoo. This water-based, odorless product is safe for all vehicle interiors. Do not wet or soak any interior surface that plain water would cause to deteriorate, as this product will have the same effect. Also avoid letting this product come into contact with vinegar or any acidic substance. Acid-based products will hamper the effectiveness of, or render GM Vehicle Care Odor Eliminator inert.

If lost, contact 800-977-4145 to get a replacement set faxed or e-mailed to your dealership. Instructions and cautions are printed on the bottle, but additional help is available. If you encounter a difficult to eliminate or reoccurring odor, you may call 1-800-955-8591 (in Canada, 1-800-977-4145) to obtain additional information and usage suggestions. Important: This product may effectively remove odors when directly contacting the odor source. It should be used in conjunction with diagnostic procedures (in cases such as a water leak) to first eliminate the root cause of the odor, and then the residual odor to permanently correct the vehicle condition. Vehicle Waterleak Odor Elimination STEP ONE: Confirm that all water leaks have been repaired. Determine what areas of the vehicle were water soaked or wet. Components with visible mold/mildew staining should be replaced. Isolate the odor source inside the vehicle. Often an odor can be isolated to an area or component of the vehicle interior by careful evaluation. Odor evaluation may need to be performed by multiple persons. Another method of isolating an odor source is to remove and segregate interior trim and components. Plastic sheeting or drop cloths can be used to confine seats, headliners, etc. to assist in evaluation and diagnoses. If appropriate the vehicle and interior trim should be evaluated separately to determine if the odor stays with the vehicle or the interior components. Odors that stay with the vehicle may be isolated to insulating and sound deadening materials (i.e. water leak at the windshield or standing water in the front foot well area caused mold/mildew to form on the bulkhead or kick panel sound deadening pads. If the interior is removed the floor pan and primed/painted surfaces should be treated with bleach/soap solution, rinsed with clean water and dried. Interior surfaces should then be treated with GM Vehicle Care Odor Eliminator product before reinstalling carpet or reassembling.

You should understand the basic theory of electricity, and know the meaning of voltage (volts), current (amps), and resistance (ohms). You should also be able to read and understand a wiring diagram, as well as understand what happens in a circuit with an open or a shorted wire. Decimal and Metric Equivalents Decimal and Metric Equivalents Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16264 Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16265 Checking Aftermarket Accessories CHECKING AFTERMARKET ACCESSORIES Do not connect aftermarket accessories into the following circuits: - CAUTION: Refer to SIR Caution. SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16266 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16267 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16268 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16269 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16270 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16271 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16272 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16273 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16274 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16275 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16294 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16339 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16340 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16341 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Fan > Component Information > Diagrams > Diagram Information and Instructions > Page 16342 1.

Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 4. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent american wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 5. Slide a section of high temperature SCT1 shrink tubing down the length of wire to be spliced. Ensure that the shrink tubing will not interfere with the splice procedure. 6. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 7. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 8. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 9.

Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16374 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16375 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16376 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16377 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16378 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16379 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16380 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16381 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16382 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16383 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16401 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors.

The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16402 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16447 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16448 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 16449 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice.

Left heated seat switch - Right heated seat switch - Heated seat module - Left seat cushion heater element - Left seat back heater element - Left seat temperature sensor - Right seat cushion heater element - Right seat back heater element - Right seat temperature sensor - Climate Control Panel (CCP) - HTD/SEAT 10 A POWER AND GROUND Battery positive voltage is supplied at all times to the heated seat module from the HTD/SEAT fuse located in the I/P fuse block. This voltage is used by the module to supply power to the seat heating elements. The module is grounded through the module ground circuit and G301. HEATED SEAT OPERATION The driver and passenger heated seats are controlled by a single heated seat module that is located under the driver seat cushion. Both heated seats are controlled by separate heated seat switches that are located in the climate control panel (CCP). When a heated seat switch is pressed, the CCP sends a GMLAN message via the serial data line to the heated seat module indicating the heated seat command. In response to this signal, the heated seat module then applies battery positive voltage through the element supply voltage circuit to the appropriate seat heating elements. The heated seat module then sends a GMLAN message back to the CCP to either illuminate or turn off the appropriate temperature indicator. TEMPERATURE REGULATION When the ignition is turned to the ON position, the heated seats will initialize in the OFF state. With each activation of the heated seat switch, the heated seat module will cycle the temperature setting in the following manner: HIGH, LOW, and OFF. The heated seat system is designed in order to warm the seat cushion and seat back to approximately 42°C (107.6°F) when in the high heat position, and 37°C (98.6°F) when in the low heat position. The heated seat module monitors the seat temperature through the temperature sensor signal circuit and the temperature sensor (thermistor) that is located in the seat cushion. The temperature sensor is a variable resistor, it's resistance changes as the temperature of the seat changes. When the temperature sensor resistance indicates to the heated seat module that the seat has reached the desired temperature, the module opens the ground path of the seat heating elements through the heated seat element control circuit. The module will then cycle the element control circuit open and closed in order to maintain the desired temperature. LOAD MANAGEMENT The load-shed operation is a means of reducing vehicle electrical loads during a low voltage or low battery state of charge (SOC) condition. During certain load-shed conditions, all heated seat functions will be disabled. Refer to Electrical Power Management Description and Operation.

Note This condition may be intermittent, therefore it is important to check if a revised calibration has been released on TIS2WEB for this concern, even if the condition cannot be duplicated at the dealer. Cause This condition may be caused by the heated seat module discharging the battery. The module keeps the serial data bus active, which creates a cumulative, continuous amperage draw on the battery after the vehicle is shut down, until the state of charge reaches three volts. Correction Important DO NOT replace the heated seat module or the battery for this concern. Reprogram the heated seat module with the latest software calibration. Important Select the correct calibration files for the appropriate vehicle configuration (body style) and RPO codes. A revised calibration has been developed to address this condition.

Whenever the brake pedal is applied, the BPPS applies a variable voltage signal to the BCM through the stop lamp switch signal circuit. The BPPS calibration must be performed after the BPPS or body control module (BCM) have been serviced. The calibration procedure will set BPPS home value. This value is used by the BCM to determine the action of the driver applying the brake system and to provide this information to the vehicle subsystems via the communication bus. CALIBRATION PROCEDURE - Install a scan tool. - Turn ON the ignition, with the engine OFF. - Select Diagnostics. - Select the year. - Select the vehicle type. - Select BCM. - Select Module Setup. - Select the BPPS calibration procedure and follow the directions displayed on the screen.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16653 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16654 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16655 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16656 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16657 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16658 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16659 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16660 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16661 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16662 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16680 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16681 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16726 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16727 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16728 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure.

Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16735 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16736 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 16737 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise.

Maintaining proper tire pressures is an Owner's Maintenance item and is not covered under warranty. This bulletin is being revised to add model years and update additional bulletin reference information. Please discard Corporate Bulletin Number 09-03-16-002 (Section 03 -- Suspension). Customer Concerns and Confusion with the Tire Pressure Monitoring (TPM) System The following procedure should be used by dealership service consultants when a customer comes into the service drive with a "low tire light" on or comments on a check tire pressure/low tire pressure/add air to tire or service tire monitor system message. The service consultant should perform the following steps: Procedure Turn the key to ON, without starting the engine. ^ If the low tire light comes on and stays on solid with a check tire pressure/low tire pressure/add air to tire message (on vehicles equipped with DIC), advise the customer: - The system is working properly. - Properly adjusting all tire air pressures to the recommended levels and driving the vehicle will turn the light off (refer to the Tire and Loading Information label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". ^ If the Tire Pressure Monitor (TPM) light blinks for one minute then stays on solid with a service tire monitor system message (on vehicles equipped with DIC): - A TPM system problem exists. The vehicle should be written up accordingly and sent to your service department for further DTC diagnosis and service. - If dashes (--) are displayed in only one or two of the tire pressure readouts, it is likely caused by a previous TPM system relearn that was performed incorrectly due to interference from another vehicle's TPM system during the relearn process (refer to the Important statement later in this bulletin regarding TPM relearn with a Tech 2(R)). - If dashes (--) are displayed in all four of the tire pressure readouts, there is a system problem. Follow the appropriate SI service procedures. ^ If a customer indicates the low tire light comes on for a few minutes when the vehicle is started, then goes off after driving a while, advise the customer: - The system is working properly. - Most likely, air pressure in one or more of the tires is low enough to turn the light on when tires are cold. After driving for a while, tires will heat Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Low Tire Pressure Indicator > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 16777 up, allowing tire air pressure to increase above the threshold causing the light to go off. Properly adjusting all tire air pressures to the recommended levels will correct this (Refer to the Tire and Loading Information Label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". For more detailed information, refer to Corporate Bulletin Number 07-03-16-004C and TPMS Training Course 13044.12T2. Tire Pressure Light At key on, without starting the vehicle: Steady Solid Glowing TPM Indicator If the TPM indicator appears as a steady glowing yellow lamp (as above), the system is functioning properly and you should add air to the tires to correct this condition. Blinking TPM Indicator If the TPM indicator appears as a BLINKING yellow lamp for one minute and then stays on solid, diagnostic service is needed. The Effect of Outside Temperature on Tire Pressures Important: As a rule of thumb, tire pressure will change about 7kPa (1 psi) for every 6°C (10°F) decrease in temperature - Tire pressure will drop when it gets colder outside, and rise when it gets warmer. Under certain situations such as extreme outside temperature changes, the system may bring on a solid light with a check tire pressure message. This should be considered normal and the system is working properly. The light will turn off upon adding the proper amount of air to the tires (refer to the Tire & Loading Information label in the driver's door opening). When properly adjusting tire air pressure, the following steps are important to help optimize the system and prolong bringing a tire pressure light on: ^ Use an accurate, high quality tire pressure gauge. ^ Never set the tire pressure below the specified placard value regardless of tire temperature or ambient temperature. ^ Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will encounter during operation. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Low Tire Pressure Indicator > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 16778 ^ When adding proper tire air pressure, it is important to remember fluctuations in outside air temperatures and tire temperatures effect tire air pressures. ^ After you have added the proper tire pressure, if the vehicle has a DIC (after the system has updated), check to see if DIC displays are the same readings as the tire pressure gauge used (adjust as necessary). ^ Only perform a TPM sensor re-learn after a tire rotation or system part replacements and use the Tech 2(R) to initiate the relearn whenever possible to avoid invalid sensor I.D. learns. Important: Always take outside temperature and tire temperature into consideration to properly set tire pressures. Foe example, on colder days (20°F/-7°C), if setting tire pressure when the vehicle has been indoors (60°F/16°C) or the tires are warm from being driven, it will be necessary to compensate for the low outside temperature by adding 21-27 kPa (3-4 psi) more then the placecard pressure. At some later time, when the vehicle has been parked outside for a while, the tires will cool off and the pressures will drop back into the placecard range. Important: Recently, nitrogen gas (for use in inflating tires) has become available to the general customer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. Tires inflated with nitrogen gas may exhibit less of a pressure change in response to outside temperature changes. Nitrogen gas inflation is compatible with GM TPM sensors. For additional information, refer to Corporate Service Bulletin 05-03-10-020C. Important: All Models (Except the Pontiac Vibe): Do not perform a TPM relearn at PDI, the system has already been set at the Assembly Plant. Do not perform a TPM relearn after adding air to the tires. The low tire light is similar to the low fuel indicator and adding something (fuel, air) to the vehicle makes that light turn back off again. Note that because of system behavior, some vehicles must be driven a short distance before the sensors recognize the increase in pressure and turns the light off again. Pontiac Vibe Only: Do not use the TPMS reset button to turn off the light. The system will update and light will turn off when all tire pressures have been adjusted followed by short distance drive. Important: All models (except the Pontiac Vibe): Each tire monitor sensor is learned to a specific vehicle corner. When performing a TPM relearn (only after a tire rotation or replacement of a TPM sensor or Module), always use the Tech2(R) to initiate the J 46079 relearned process. Tech 2(R) - initiated relearns lock out other vehicle TPM signals that may be broadcasting in the area. Only signals initiated by the J 46079 tool will be accepted. This method avoids storing false TPM I.D.s and will prevent customers from returning with dashes (--) displayed in tire pressure readouts and/or a flashing tire pressure monitor (TPM) light. Checking the four TPM I.D.s with the Tech 2(R) prior to and following relearn to verify they are the same can prevent invalid I.D. learns. Pontiac Vibe Only: Tire Monitor Sensors are not learned to a specific vehicle corner. Do not perform a TPM Reset after tire rotation. The TPMS Reset button must only be used during pre-delivery inspection by the dealer to initialize the system (after all tire pressures have been adjusted properly) or when a Tire Pressure Monitor System component is replaced. The J 46079 tool does not work on Vibe TPM sensors. A TPMS relearn on Vibe must be preformed with a Tech 2(R) to set the TPMS Module in learn mode. The TPMS sensor IDs are entered through the Tech 2(R). Refer to SI for further Vibe TPMS information. Labor Operation and Repair Order/Warranty System Claim Required Documentation Important: The ONLY time labor operation E0726 or E0722 should be used is to diagnose for a system issue. That should ONLY occur if, at key ON, without starting the engine, the Tire Pressure Monitor (TPM) blinks for one minute and then stays on solid with a Service Tire Monitor System message (on vehicles equipped with a DIC) If that occurs, a TPM system problem exists and the system will have set a DTC. If one of these operastions is used, the following Repair Order and Warranty System documentation are required: ^ Document the customer complaint on the Repair Order. ^ Document the TPMS DTC that has set on the Repair Order. ^ Enter the TPMS DTC in the Warranty System (WINS) in the Failure Code/DTC field on the claim submission (refer to the Claims Processing Manual, Section IV, Warranty claim Data, Page 6, Item G). If the above information is not documented on the Repair Order and Warranty System, the claim may be rejected.

Supercede: This bulletin is being revised to add information for the 2011 model year and add new 2011 vehicles. Please discard Corporate Bulletin Number 07-08-49-020C (Section 08 - Body and Accessories). The purpose of this bulletin is to provide a reference guide to help identify which season odometer programming method to use after replacing the instrument panel cluster (IPC). The three season odometer programming methods in use today are listed below. In addition, this reference guide lists the component where the season odometer value is stored. The season odometer value may be stored in the IPC, the driver information center (DIC) or the integrated body control module (IBCM), also commonly called a body control module (BCM). Season Odometer Programming Methods in Use Today 1. IPC reprogramming and setup using the service programming system (SPS). 2. Odometer setup at the electronic service center (ESC) when using an exchange IPC/DIC. 3. Tech 2(R) - The Tech 2 is used to set up a replacement BCM, which includes loading the odometer value that is displayed and stored in the IPC. A replacement IPC will display the previously stored vehicle odometer value, communicated from the BCM, after cycling the ignition or driving the vehicle. *The odometer programming is integrated as part of the BCM programming procedure. It is not a stand-alone event.

This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A "CHANGE ENGINE OIL SOON" message will come on. Change your oil as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. It is also important to check your oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed. HOW TO RESET THE ENGINE OIL LIFE SYSTEM The Engine Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a change engine oil light being turned on, reset the system. 1. Turn the ignition key to "RUN" with the engine off. 2. Fully press and release the accelerator pedal three times within five seconds. The "CHANGE ENGINE OIL SOON" message will flash while the system is resetting. 3. When the light stops flashing, turn the key to "LOCK". If the change engine oil light comes back on and stays on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure. WHAT TO DO WITH USED OIL Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.

Maintaining proper tire pressures is an Owner's Maintenance item and is not covered under warranty. This bulletin is being revised to add model years and update additional bulletin reference information. Please discard Corporate Bulletin Number 09-03-16-002 (Section 03 -- Suspension). Customer Concerns and Confusion with the Tire Pressure Monitoring (TPM) System The following procedure should be used by dealership service consultants when a customer comes into the service drive with a "low tire light" on or comments on a check tire pressure/low tire pressure/add air to tire or service tire monitor system message. The service consultant should perform the following steps: Procedure Turn the key to ON, without starting the engine. ^ If the low tire light comes on and stays on solid with a check tire pressure/low tire pressure/add air to tire message (on vehicles equipped with DIC), advise the customer: - The system is working properly. - Properly adjusting all tire air pressures to the recommended levels and driving the vehicle will turn the light off (refer to the Tire and Loading Information label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". ^ If the Tire Pressure Monitor (TPM) light blinks for one minute then stays on solid with a service tire monitor system message (on vehicles equipped with DIC): - A TPM system problem exists. The vehicle should be written up accordingly and sent to your service department for further DTC diagnosis and service. - If dashes (--) are displayed in only one or two of the tire pressure readouts, it is likely caused by a previous TPM system relearn that was performed incorrectly due to interference from another vehicle's TPM system during the relearn process (refer to the Important statement later in this bulletin regarding TPM relearn with a Tech 2(R)). - If dashes (--) are displayed in all four of the tire pressure readouts, there is a system problem. Follow the appropriate SI service procedures. ^ If a customer indicates the low tire light comes on for a few minutes when the vehicle is started, then goes off after driving a while, advise the customer: - The system is working properly. - Most likely, air pressure in one or more of the tires is low enough to turn the light on when tires are cold. After driving for a while, tires will heat Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Tire Monitoring System > Low Tire Pressure Indicator > Component Information > Technical Service Bulletins > Tire Pressure Monitor - TPM System Message/Service Tips > Page 16831 up, allowing tire air pressure to increase above the threshold causing the light to go off. Properly adjusting all tire air pressures to the recommended levels will correct this (Refer to the Tire and Loading Information Label on the driver side door). - More detailed information can be found in the Owner Manual. - Service is not covered under warranty - this maintenance is the responsibility of the owner. - Give the customer a copy of the "GM Customer TPMS Information". For more detailed information, refer to Corporate Bulletin Number 07-03-16-004C and TPMS Training Course 13044.12T2. Tire Pressure Light At key on, without starting the vehicle: Steady Solid Glowing TPM Indicator If the TPM indicator appears as a steady glowing yellow lamp (as above), the system is functioning properly and you should add air to the tires to correct this condition. Blinking TPM Indicator If the TPM indicator appears as a BLINKING yellow lamp for one minute and then stays on solid, diagnostic service is needed. The Effect of Outside Temperature on Tire Pressures Important: As a rule of thumb, tire pressure will change about 7kPa (1 psi) for every 6°C (10°F) decrease in temperature - Tire pressure will drop when it gets colder outside, and rise when it gets warmer. Under certain situations such as extreme outside temperature changes, the system may bring on a solid light with a check tire pressure message. This should be considered normal and the system is working properly. The light will turn off upon adding the proper amount of air to the tires (refer to the Tire & Loading Information label in the driver's door opening). When properly adjusting tire air pressure, the following steps are important to help optimize the system and prolong bringing a tire pressure light on: ^ Use an accurate, high quality tire pressure gauge. ^ Never set the tire pressure below the specified placard value regardless of tire temperature or ambient temperature. ^ Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will encounter during operation.

The driver information center (DIC), if equipped, will also display a SERVICE TIRE MONITOR type message. When the road tire is repaired and reinstalled in the original location, the TPM indicator icon illumination and DIC message may remain displayed until the DTC is cleared. To ensure that the TPM indicator and the DIC message are cleared after service, it is necessary to clear any TPM DTCs using a scan tool. If a scan tool is unavailable, performing the TPM relearn procedure using a TPM diagnostic tool will provide the same results. It is advised to perform the relearn procedure away from other vehicles to prevent picking up a stray sensor signal. If one or more of the TPM sensors are missing or damaged and have been replaced, then the relearn procedure must be performed.

Important: Operational TPM Sensors that are returned under warranty to General Motors will be charged back to the dealer.Sensors have a 10 year /150,000 mile (240,000 km) battery life, and should be transferred if one or more wheels are replaced. TPM Valve Stem / Grommet (0-ring) Replacement When the TPM sensors are transferred to new wheels you should replace the component used to seal the TPM sensor stem to the wheel. On sensors with an aluminum stem and visible nut on the outside of the wheel a replacement grommet (0-ring) should be used to assure a proper seal. The sensor retaining nut (except Aveo) should be tightened to 7 N.m (62 lb in) for all vehicles except Pontiac Vibe (4.0 N.m (35.4 lb in)). Important: ^ DO NOT overtorque the retaining nut. Notice: ^ Factory installed TPM Sensors come with plastic aluminum or nickel-plated brass stem caps. These caps should not be changed. Chrome plated steel caps may cause corrosion of aluminum valve stems due to incompatibility of the metals. On current style sensors the entire rubber stem is replaceable. The service interval on the revised TPM sensor with replaceable stem is the same as for any other traditional valve stem. Replace the stem at the time of tire replacement sensor transfer or whenever air seepage is suspected at the valve stem. When replacing the valve stem tighten the screw to 1.3 N.m (11.5 lb in). For either style of TPM sensor see the service parts guide for the correct GM part numbers to order and use.

The driver information center (DIC), if equipped, will also display a SERVICE TIRE MONITOR type message. When the road tire is repaired and reinstalled in the original location, the TPM indicator icon illumination and DIC message may remain displayed until the DTC is cleared. To ensure that the TPM indicator and the DIC message are cleared after service, it is necessary to clear any TPM DTCs using a scan tool. If a scan tool is unavailable, performing the TPM relearn procedure using a TPM diagnostic tool will provide the same results. It is advised to perform the relearn procedure away from other vehicles to prevent picking up a stray sensor signal. If one or more of the TPM sensors are missing or damaged and have been replaced, then the relearn procedure must be performed.

When dismounting and mounting tires, care must be taken when breaking the bead loose from the wheel. If the tire machines bead breaking fixture is positioned too close to the tire pressure sensor, as the tire bead breaks away from the wheel it may be forced into, or catch on the edge of the tire pressure sensor. This can damage the sensor and require the sensor to be replaced. Care must also be taken when transferring the tire bead to the other side of the wheel rim. As the tire machine rotates and the tire bead is stretched around the wheel rim, the bead can come in contact with the sensor if it is not correctly positioned in relation to the mounting/dismounting head prior to tire mounting/dismounting. This can also cause sensor damage requiring replacement. Procedure Notice: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result. Notice: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel. 1. Remove the valve core from the valve stem. 2. Deflate the tire completely. Important: Rim-clamp European-type tire changers are recommended. 3. Use the tire changer in order to remove the tire from the wheel. Follow steps 4-7 to remove the tire from the wheel. 4. When separating the tire bead from the wheel position the bead breaking fixture 90, 180 and 270 degrees from the valve stem.

Position the wheel and tire so the valve stem is situated at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the outer tire bead up and over the mounting/dismounting head. 6. Position the wheel and tire so that the valve stem is situated again at the 2 o'clock position relative to the head. The tire iron or pry bar can be inserted when prying the inner tire bead up and over the mounting/dismounting head. 7. Remove all residual liquid sealant from the inside of the tire and wheel surfaces. If any tire sealant is noted upon tire dismounting on vehicles equipped with TPM replace the tire pressure sensor. 8. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats. Important: If bead seat corrosion has been identified as an air loss concern on the wheel being worked on, refer to GM Service Bulletin # 08-03-10-006 for additional information on correcting the leak. 9. Apply GM P/N 12345884 (in Canada, P/N 5728223) or equivalent to the tire bead and the wheel rim.

Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim. 11. Position the rim so that the valve stem (1) is situated at the 3 o'clock position relative to the head (2). This will protect the sensor when the bottom bead seats. 12. After the bottom bead is on the wheel, reposition the wheel and tire so that the valve stem is situated at the 9 o'clock position relative to the head. This will protect the sensor while mounting the tire bead to the outside of the wheel.

Use the tire changer in order to install the tire to the wheel. Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, lubricate the beads and reinflate. Overinflating may cause the bead to break and cause serious personal injury. Important: Allowable bead seating pressure is 345 kPa (50 psi) on Extended Mobility Tires. 14. Inflate the tire until it passes the bead humps. Be sure that the valve core is not installed at this time. 15. Install the valve core to the valve core stem. 16. Inflate the tire to the proper air pressure. 17. Ensure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.

Please discard Corporate Bulletin Number 02-08-42-0004 (Section 08 - Body and Accessories). After backing the vehicle out of a garage or dark environment into a daylight environment, the PRNDL display has reduced visibility for approximately one minute. While the vehicle is parked in a dark environment, the sensor for the automatic headlamp/driving lamps senses that it is dark. When the key is turned to the run/start position, the automatic headlamp module will turn all driving lamps, the instrument panel cluster and PRNDL display ON in the night-time mode. The night-time mode intensity of the instrument panel lamps and PRNDL display is controlled by the automatic headlamp module and can be dimmed further by the customer using the dimming control of the headlamp switch. When the customer then moves the vehicle from the dark environment into the bright sunlight, it will take approximately one minute before the headlamp control module recognizes this as true daylight and not just a bright overhead street lamp shining on the sensor. The headlamp control module will then turn the headlamps off and restore the instrument panel and PRNDL display to full brilliance. Without the time delay, the automatic headlamp control module would switch to the night mode (turn on all driving lamps, instrument panel lamps and PRNDL display would dim) each time the vehicle was driven under an overpass or other darkened environment. This is a normal condition and no repair should be attempted. Ensure the instrument panel backlighting control is in the full bright position. This will help alleviate the condition. You may demonstrate to the customer what happens by placing a repair order over the automatic headlamp control light sensor, which will cause the automatic headlamp control module to switch to the night mode in approximately one minute. All driving lamps will come ON, the instrument panel backlight will be dim, and the PRNDL display will also dim to the night setting in conjunction with the position of the headlamp switch dimming control. Demonstrate to the customer the variance in the instrument panel backlighting and PRNDL display while adjusting the headlamp switch dimming control to both ends of its allowable range. Advise the customer to keep the headlight switch dimming control in the highest position to allow viewing of the PRNDL display in a bright environment.

Please discard Corporate Bulletin Number 01-08-42-001G (Section 08 - Body and Accessories). The following information is being provided to better define the causes of condensation in exterior lamps and includes guidelines for determining the difference between a lamp with a normal atmospheric condition (condensation) and a lamp with a water leak. Some exterior lamps, such as cornering, turn signal, backup, headlamps or tail lamps may exhibit very small droplets of water, a fine mist or white fog (condensation) on the inside of the lamp lens. This may be more noticeable on lamps with "multi-lens" designs and may be normal during certain weather conditions. Condensation occurs when the air inside the lamp assembly, through atmospheric changes, reaches the "dew point". When this takes place, the moisture in the air within the lamp assembly condenses, creating a fine mist or white fog on the inside surface of the lamp lens. Most exterior lamps on General Motors vehicles use a vented design and feature a replaceable bulb assembly. They are designed to remove any accumulated moisture vapor by expelling it through a vent system. The vent system operates at all times, however, it is most effective when the lamps are ON or when the vehicle is in motion. Depending on the size, shape and location of the lamp on the vehicle, and the atmospheric conditions occurring, the amount of time required to clear the lamp may vary from 2 to 6 hours. Completely sealed headlamp assemblies (sealed beams) are still used on a limited number of models being manufactured today. These lamps require the replacement of the complete lamp assembly if a bulb filament burns out. Condensation 2006 TrailBlazer Shown A Fine Mist or White Fog on the Inside Surface of the Lamp Lens Occurring After a Period of High Humidity - May be located primarily in the lens corners (near the vents) and SHOULD NOT cover more than half the lens surface. - The condition should clear of moisture when the vehicle is parked in a dry environment, or when the vehicle is driven with the lights ON. - A comparison of the equivalent lamp on the opposing side of the vehicle indicates a SIMILAR performance. If the above conditions are noted, the customer should be advised that replacement of a lamp assembly may not correct this condition.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16886 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16887 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16888 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6.

Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16890 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16891 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16892 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16893 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16894 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16895 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16913 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal. Insulation should be visible on both sides of the terminal insulation wings. 6. Compress the handles until the ratchet automatically releases. 7. Place the terminal into the appropriate cavity and assemble the connector. Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16914 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16959 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16960 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16961 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire.

Use the Splice Crimp Tool from the J-38125 to crimp DuraSeal splice sleeve. In order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Gradually move the heat barrel to the open end of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. CONNECTOR POSITION ASSURANCE (CPA) The connector position assurance (CPA) is a small plastic insert that fits through the locking tabs of a connector. CPAs are used in all SIR System connectors and also in some connectors of other systems. The CPA ensures that the connector halves cannot vibrate apart. You must have the CPA in place in order to ensure good contact between the mating terminals of a connection. TERMINAL POSITION ASSURANCE (TPA) The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.

Refer to Splicing Copper Wire Using Splice Sleeves. TOOLS REQUIRED J-38125 Terminal Repair Kit 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16968 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16969 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 16970 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17007 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17008 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17009 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17010 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17011 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17012 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17013 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17014 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17015 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17016 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17035 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17080 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17081 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17082 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17089 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17090 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17091 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Courtesy Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17092 4. IMPORTANT: Apply the mylar tape with the aluminum side inward. This ensures good electrical contact with the drain wire. Re-assemble the cable. Rewrap the conductors with the mylar tape. - Use caution not to wrap the drain wire in the tape (1). - Follow the splicing instructions for copper wire and splice the drain wire. - Wrap the drain wire around the conductors and tape with mylar tape. 5. Tape over the entire cable. Use a winding motion when you apply the tape.

Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Headlamp > Headlamp Lens > Component Information > Technical Service Bulletins > Lighting - Headlamp Polycarbonate Lens Damage Prevention Headlamp Lens: Technical Service Bulletins Lighting - Headlamp Polycarbonate Lens Damage Prevention INFORMATION Bulletin No.: 02-08-42-001D Date: June 21, 2010 Subject: Headlamp Lens Overheating When Covered and Chemical Damage to Exterior Polycarbonate Headlamp Lenses Models: 2011 and Prior GM Passenger Cars and Trucks (Including Saturn) 2010 and Prior HUMMER H2, H3 2009 and Prior Saab 9-7X Supercede: This bulletin is being revised to add model years and to revise the warning statements. Please discard Corporate Bulletin Number 02-08-42-001C (Section 08 - Body and Accessories). The bulletin is being issued to make dealers and customers aware of chemical damage that may be caused to exterior polycarbonate headlamp lenses. Most late model vehicles have these types of headlamp lenses. This material is used because of its temperature and high impact resistance. A variety of chemicals can cause crazing or cracking of the headlamp lens. Headlamp lenses are very sensitive. Care should be exercised to avoid contact with all exterior headlamp lenses when treating a vehicle with any type of chemical, such as those recommended for rail dust removal. Rubbing compound, grease tar and oil removers, tire cleaners, cleaner waxes and even car wash soaps in too high a concentration may also attribute to this condition. This could result in the need to replace the entire headlamp housing. Warning Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Also, crazing or deformations of the lens may occur if a shop mat or fender cover is draped over the fender and covers a portion or all of the headlamp assembly while the DRL or headlamps are on. This action restricts the amount of heat dissipated by the headlamps. Warning Care should be taken to not cover headlamps with shop mats or fender covers if the vehicle is being serviced with the headlamps or DRL illuminated. Covering an illuminated lamp can cause excessive heat build up and crazing/deformation of the lens may occur. The degradation of the lens can be unnoticeable at first and eventually become hairline cracks in the lens. In extreme cases, it could cause the lens to deform. This damage can also be caused by aftermarket shields that are often tinted in color. Once a heat buildup is generated by the headlamp, a degradation of the headlamp lens begins. This degradation of the lens can be unnoticeable at first and eventually manifest as spider cracks. In more extreme cases, it will begin to melt the lens of the headlamp. Notice Headlamps damaged by chemicals, improper cleaning, or overheating due to being covered are not covered under the new vehicle warranty.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17286 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17287 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17288 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17289 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17290 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17291 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17292 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17293 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17294 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17295 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17359 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17360 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 17361 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125 and then encapsulate the splice sleeve using the high temperature SCT1 shrink tubing.

For Chevrolet Tahoe, Suburban, GMC Yukon, and Cadillac Escalade vehicles (with moveable glass), always replace the defroster tab (GM P/N 25916031) and the defroster electrical power connector (P/N 12034110). For all other vehicles, reconnect the original defroster tab. In most applications it is preferable to create a new solder connection to reattach a separated rear defroster tab. If you take note of the steps below, it is possible to create a new solder joint that is equal to, or stronger than, the original. The generic procedure below is not very time intensive, but does include minor preparation work to create a good bonding surface. Be sure to follow each of the steps, as combined they will produce the strongest bond possible. Please consider the following before attempting the repair: - Soldering introduces significant heat to the glass window of the vehicle. When performing the re-connection of the tab, use only the heat required to do the job. Pre-heat the soldering iron and have the solder in your other hand, ready to go, the moment you have enough heat to melt the solder. - If it is winter, bring the vehicle into the service garage and remove any snow from the back window area. Allow time for the glass to warm to the temperature inside the building. Soldering creates a "hot spot" in the glass. DO NOT solder on cold glass. Caution Heating the glass excessively, or repeatedly without time to cool, may result in glass breakage. ALWAYS wear safety glasses when performing this repair! - You MUST use a silver-bearing solder to make the connection. DO NOT attempt this repair with conventional tin/lead alloy solders. Silver bearing solder will adhere to the electrical buss bar, making a strong and lasting repair. - Protect surfaces under the area to be soldered. It is very easy to drip solder when performing this repair. Placing a shop towel under the soldering area is sufficient protection. Soldering Procedure 1. It is imperative to remove and replace the rear defroster electrical power connector by crimping a new connector to the feed wire. The proper connector P/N 12034110 can be found in the Packard Electrical Assortment, Tray 18, Position 5. - Insert Delphi pick 12094430 to depress the locking tab on the terminal. - Insert Delphi pick 12094429 to release the secondary lock tab. Important DO NOT re-use the existing defroster tab on new-style full-size utility vehicles with moveable glass. 2. Connect the electrical connector to the defroster tab. Fully engage the connector. An improperly seated connector may cause excessive resistance and impede the proper operation of the defroster. Add a small bead of solder to mate the electrical connector tab to the defroster tab.

Prepare the surface of the used defroster tab (not required for new tabs on new-style full-size utility models) and the defroster buss bar with fine grain (500 grit) sandpaper or Emery cloth. It is not necessary to remove all of the original solder, but it should be scuffed sufficiently so that no oxidation is present. The photo above shows a close up of a properly prepared surface. Tip You may want to mask the glass around the contact area with tape. This is easy to do and will allow you to safely prepare the contact surface without the risk of scratching the glass or the black painted shading. Important Most rear glass has a black painted masking around the edge of the glass. When cleaning up the connection surface, be very careful not to damage the surface of the black shading or the surface of the glass. 4. Wipe the newly prepared contact area with Kent Automotive* Acrysol(TM) (or equivalent) to remove any residual oil or dirt.

DO NOT attempt this repair with conventional tin/lead alloy solders. Most suppliers have this type of solder available and it is available nationally at Radio Shack(R)*. It is sold in several diameters and either are acceptable for this repair. 5. For this step, it is permitted that two technicians be used if required. Heat the new connector on the surface of the buss bar that is to be soldered. Long nose pliers are suggested to hold the electrical connector and the defroster tab in place. Keep the solder ready and begin flowing out the solder as soon as the melting temperature has been reached. Tip If a single technician is attempting this repair, it is beneficial to wrap one turn of the solder around the new contacts base. In this manner, as the melting point of the solder is reached, a layer is deposited on the bottom side of the contact. Important Try to align the new contact so that it is positioned with the same orientation as the original contact. 6. The above illustrates an ideal finished solder joint. Additional stray solder will not harm the performance of the bond; however, while it is unlikely that customers may refer to the appearance of the rear window defroster and its components as a positive styling feature of the vehicle interior, it is easy to elicit the opposite reaction due to a poor cosmetic application. *We believe this source and their products to be reliable.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17407 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17408 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17409 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17410 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17411 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17412 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17413 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17414 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17415 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17416 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

REPAIR PROCEDURE Follow the steps below in order to repair Micro 64 connector terminals. The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also designed to crimp both the wire and the insulation at the same time. After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 terminals. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. 1. Cut the wire as close to the damaged terminal as possible. 2. Strip 5 mm (3/16 in) of insulation from the wire. 3. Depress the spring loaded locator of the crimping tool until the terminal holder is completely visible. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17434 4. Insert terminal into the appropriate terminal holder until it hits bottom and stops. The correct terminal holder is determined by the wire size. Also ensure that the terminals wings are pointing towards the former on the tool and the release locator. 5. Insert the stripped cable into the terminal.

Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17435 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17436 3. Use a small flat-blade tool to push in one of the locking tabs while gently pulling on the same side of the nose piece. 4. Repeat the procedure for the other locking tab and remove the nose piece. 5. Remove the wire dress cover. The following is a general procedure for wire dress cover removal. Use this procedure as a guide, some dress cover removal procedures may vary. 6. Use fingers to squeeze the 2 locking legs of the cover. 7. Apply pressure and gently rock the cover until one locking leg is unseated. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17437 8. Continue to apply pressure and rock the cover until the second locking leg is unseated. Repeat procedure for the other side of the dress cover and remove the cover. 9. Use J 38125-12A (GM P/N 12094429) to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector. See the release tool cross reference in the Reference Guide of the J-38125 to ensure that the correct release tool is used. 10. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17438 3. Depress the spring loaded locator of the J 38125-101 (W jaw) crimping tool until the terminal holder is completely visible. 4. Insert the terminal into the crimp tool until the core wings are flush with the anvil on the crimp tool. Be sure that the wings are pointed toward the crimp tool former and release the spring locator. The locator will hold the terminal in place. Inspect the alignment of the terminal wings with the crimp tool former. If the terminal wings are wider than the crimp tool former, remove the terminal and bend the terminal wings in slightly. 5. Place stripped wire into terminal. 6. Crimp the new terminal to the wire. If a jam occurs, press the emergency release to open applicator. TERMINAL REPLACEMENT PROCEDURE After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals. 1. Slide the new terminal into the correct cavity at the back of the connector. 2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire. 3. To assemble the connector, reverse the Terminal Removal Procedure.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17480 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17481 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17482 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire.

Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17490 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17491 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Diagrams > Diagram Information and Instructions > Page 17492 4. IMPORTANT: Apply the mylar tape with the aluminum side inward. This ensures good electrical contact with the drain wire. Re-assemble the cable. Rewrap the conductors with the mylar tape. - Use caution not to wrap the drain wire in the tape (1). - Follow the splicing instructions for copper wire and splice the drain wire. - Wrap the drain wire around the conductors and tape with mylar tape. 5. Tape over the entire cable. Use a winding motion when you apply the tape.

CIRCUIT/SYSTEM DESCRIPTION When you depress the rear defogger button, voltage is supplied to the DEFOG relay coil and the HVAC control module also illuminates the rear window defogger indicator. Battery positive voltage is supplied at all times to the DEFOG relay switched input and the DEFOG relay coil is always grounded. This allows battery positive voltage from the relay switched input through the switch contacts and out the relay switched output to the rear window defogger. Ground for the rear defogger grid is provided by G401. When you start the engine and press the rear defogger switch for the first time, the defogger cycle lasts for 15 minutes. Further operation results in 7.5 minute defogger cycles. The defogger cycle resets to 15 minutes when you cycle the ignition to the OFF position and then to the ON position. CIRCUIT/SYSTEM VERIFICATION 1. Ignition ON, observe the operation of the Rear Defogger Grid while pressing the Rear Defogger Switch. The Rear Defogger Grid should ACTIVATE and DEACTIVATE when changing between commanded states. 2. Command the rear window defogger indicator ON and OFF with the scan tool. The rear window defogger indicator should turn ON and OFF when changing between the commanded states. If the Defogger Indicator does not illuminate, replace the HVAC control module. CIRCUIT/SYSTEM TESTING 1. Ignition OFF, disconnect the REAR DEFOG relay. 2. Ignition OFF, test for less than 1.0 ohm of resistance between the relay coil ground circuit terminal 25 and ground. - If greater than the specified range, test for an open/high resistance. 3.

Verify that a test lamp illuminates between the relay switch B+ circuit terminal 43 and ground. - If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the RR DEFOG circuit fuse is open, test the relay controlled output circuit terminal 46 for a short to ground 5. Ignition OFF, disconnect the harness connectors C1 and C2 at the Rear Defogger Grid. 6. Ignition OFF, test for less than 1.0 ohm of resistance between the Rear Defogger Grid ground circuit terminal 1 and ground. - If greater than the specified range, test the ground circuit for an open/high resistance. 7. Connect the harness connectors at the Rear Defogger Grid. 8. Ignition ON, connect a 30-A fused jumper wire between the relay switch B+ circuit terminal 43 and the relay controlled output circuit terminal 46. Verify the Rear Defogger Grid is activated. If the Rear Defogger Grid does not activate, test the control circuit for an open/high resistance. If the circuit tests normal, test or replace the Rear Defogger Grid. 9. Connect a test lamp between the relay coil control circuit terminal 39 and the relay coil ground circuit terminal 25. 10. Command the Rear Defogger Grid ON and OFF by pressing the Rear Defogger Switch. The test lamp should turn ON and OFF when changing between the commanded states. If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the HVAC Control Module. - If the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the HVAC Control Module. 11. If all circuits test normal, test or replace the DEFOG Relay. COMPONENT TESTING Relay Test Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Windows and Glass > Heated Glass Element > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures > Page 17499 1. Ignition OFF, disconnect the REAR DEFOG relay. 2. Test for 60-180 ohms of resistance between terminals 85 and 86. - If the resistance is not within the specified range, replace the relay. 3. Test for infinite resistance between the following terminals: - 30 and 86 - 30 and 87 - 30 and 85 - 85 and 87 - If not the specified value, replace the relay. 4. Install a 25-amp fused jumper wire between relay terminal 85 and 12 volts. Install a jumper wire between relay terminal 86 and ground.

A grid line fault requires rear window replacement. 1. Start the engine. 2. Activate the rear window defogger system. 3. Connect a test lamp to a good ground. 4. IMPORTANT: The test lamp brilliance will decrease proportionately to the increased resistance in the grid line as the probe is moved from the battery positive bus wire to the ground bus wire. The test lamp brilliance may vary from one window to another. Move the test lamp probe from the positive to the negative wire. If the test lamp shows full brilliance at both ends of the grid lines, inspect for an open or poor connection in the ground circuit of the rear window defogger grid. - If the test lamp goes out, test the grid line in at least 2 places to eliminate the possibility of bridging the open in the grid line. 5. Once the open is located, replace the rear window.

RPO C49 Supercede: This bulletin is being revised to add the 2012 model year. Please discard Corporate Bulletin Number 03-08-48-006G (Section 08 - Body and Accessories). Repair Suggestions Soldering Defroster Contact Tabs In many cases the terminal tab will still be in the connector when you examine the vehicle. For Chevrolet Tahoe, Suburban, GMC Yukon, and Cadillac Escalade vehicles (with moveable glass), always replace the defroster tab (GM P/N 25916031) and the defroster electrical power connector (P/N 12034110). For all other vehicles, reconnect the original defroster tab. In most applications it is preferable to create a new solder connection to reattach a separated rear defroster tab. If you take note of the steps below, it is possible to create a new solder joint that is equal to, or stronger than, the original. The generic procedure below is not very time intensive, but does include minor preparation work to create a good bonding surface. Be sure to follow each of the steps, as combined they will produce the strongest bond possible. Please consider the following before attempting the repair: - Soldering introduces significant heat to the glass window of the vehicle. When performing the re-connection of the tab, use only the heat required to do the job. Pre-heat the soldering iron and have the solder in your other hand, ready to go, the moment you have enough heat to melt the solder. - If it is winter, bring the vehicle into the service garage and remove any snow from the back window area. Allow time for the glass to warm to the temperature inside the building. Soldering creates a "hot spot" in the glass. DO NOT solder on cold glass. Caution Heating the glass excessively, or repeatedly without time to cool, may result in glass breakage. ALWAYS wear safety glasses when performing this repair! - You MUST use a silver-bearing solder to make the connection. DO NOT attempt this repair with conventional tin/lead alloy solders. Silver bearing solder will adhere to the electrical buss bar, making a strong and lasting repair. - Protect surfaces under the area to be soldered. It is very easy to drip solder when performing this repair. Placing a shop towel under the soldering area is sufficient protection. Soldering Procedure 1. It is imperative to remove and replace the rear defroster electrical power connector by crimping a new connector to the feed wire. The proper connector P/N 12034110 can be found in the Packard Electrical Assortment, Tray 18, Position 5. - Insert Delphi pick 12094430 to depress the locking tab on the terminal. - Insert Delphi pick 12094429 to release the secondary lock tab. Important DO NOT re-use the existing defroster tab on new-style full-size utility vehicles with moveable glass. 2. Connect the electrical connector to the defroster tab. Fully engage the connector. An improperly seated connector may cause excessive resistance and impede the proper operation of the defroster. Add a small bead of solder to mate the electrical connector tab to the defroster tab.

Prepare the surface of the used defroster tab (not required for new tabs on new-style full-size utility models) and the defroster buss bar with fine grain (500 grit) sandpaper or Emery cloth. It is not necessary to remove all of the original solder, but it should be scuffed sufficiently so that no oxidation is present. The photo above shows a close up of a properly prepared surface. Tip You may want to mask the glass around the contact area with tape. This is easy to do and will allow you to safely prepare the contact surface without the risk of scratching the glass or the black painted shading. Important Most rear glass has a black painted masking around the edge of the glass. When cleaning up the connection surface, be very careful not to damage the surface of the black shading or the surface of the glass. 4. Wipe the newly prepared contact area with Kent Automotive* Acrysol(TM) (or equivalent) to remove any residual oil or dirt.

DO NOT attempt this repair with conventional tin/lead alloy solders. Most suppliers have this type of solder available and it is available nationally at Radio Shack(R)*. It is sold in several diameters and either are acceptable for this repair. 5. For this step, it is permitted that two technicians be used if required. Heat the new connector on the surface of the buss bar that is to be soldered. Long nose pliers are suggested to hold the electrical connector and the defroster tab in place. Keep the solder ready and begin flowing out the solder as soon as the melting temperature has been reached. Tip If a single technician is attempting this repair, it is beneficial to wrap one turn of the solder around the new contacts base. In this manner, as the melting point of the solder is reached, a layer is deposited on the bottom side of the contact. Important Try to align the new contact so that it is positioned with the same orientation as the original contact. 6. The above illustrates an ideal finished solder joint. Additional stray solder will not harm the performance of the bond; however, while it is unlikely that customers may refer to the appearance of the rear window defroster and its components as a positive styling feature of the vehicle interior, it is easy to elicit the opposite reaction due to a poor cosmetic application. *We believe this source and their products to be reliable.

Please discard Corporate Bulletin Number 00-08-48-005C (Section 08 - Body and Accessories). Distortion in the outer surface of the windshield glass, door glass or backlite glass may appear after the vehicle has: - Accumulated some mileage. - Been frequently washed in automatic car washes, particularly "touchless" car washes. This distortion may look like a subtle orange peel pattern, or may look like a drip or sag etched into the surface of the glass. Some car wash solutions contain a buffered solution of hydrofluoric acid which is used to clean the glass. This should not cause a problem if used in the correct concentration. However, if not used correctly, hydrofluoric acid will attack the glass, and over time, will cause visual distortion in the outer surface of the glass which cannot be removed by scraping or polishing. If this condition is suspected, look at the area of the windshield under the wipers or below the belt seal on the side glass. The area of the glass below the wipers or belt seal will not be affected and what looks like a drip or sag may be apparent at the edge of the wiper or belt seal. You may also see a line on the glass where the wiper blade or the belt seal contacts the glass.

Please discard Corporate Bulletin Number 00-08-48-005C (Section 08 - Body and Accessories). Distortion in the outer surface of the windshield glass, door glass or backlite glass may appear after the vehicle has: - Accumulated some mileage. - Been frequently washed in automatic car washes, particularly "touchless" car washes. This distortion may look like a subtle orange peel pattern, or may look like a drip or sag etched into the surface of the glass. Some car wash solutions contain a buffered solution of hydrofluoric acid which is used to clean the glass. This should not cause a problem if used in the correct concentration. However, if not used correctly, hydrofluoric acid will attack the glass, and over time, will cause visual distortion in the outer surface of the glass which cannot be removed by scraping or polishing. If this condition is suspected, look at the area of the windshield under the wipers or below the belt seal on the side glass. The area of the glass below the wipers or belt seal will not be affected and what looks like a drip or sag may be apparent at the edge of the wiper or belt seal.

Condition General Motors has decided that certain 2007 Chevrolet Equinox and Pontiac Torrent model vehicles fail to conform to Federal/Canada Motor Vehicle Safety Standard (MVSS) 212, Windshield Mounting. On some of these vehicles, an incorrect primer may have been used when installing the windshield. In the event of a crash, the windshield may not be retained to the extent required by the Standard, increasing the risk of personal injuries to the vehicle occupants. The same primer may have also been applied to the liftgate glass and the side stationary glass. Correction For vehicles in customer possession, export vehicles, certain vehicles located in remote areas, and inventory vehicles identified in the "Dealer Repaired Vehicles" report, dealers are to replace the windshield, liftgate glass, and the side stationary glass. A listing of vehicles to repair, titled "Dealer Repaired Vehicles", has been sent in the Administrative Message releasing this bulletin. For vehicles in dealer inventory (greater than one), dealers are to hold the vehicle. The General Motors Dealer Business Center will contact dealers to arrange for return of the vehicles to GM. The vehicle transport company that normally services the dealership will facilitate the vehicle pick up. The vehicles will then be inspected, repaired if necessary, and returned to dealers as quickly as possible. A listing of vehicles to be returned to GM, titled "Vehicles Returned to GM", has been sent in the Administrative Message releasing this bulletin. Each vehicle will be returned with a completed Inspection/Repair Worksheet in the vehicle. This document will clearly indicate if the vehicle passed or failed the inspection.

Please discard Corporate Bulletin Number 00-08-48-005C (Section 08 - Body and Accessories). Distortion in the outer surface of the windshield glass, door glass or backlite glass may appear after the vehicle has: - Accumulated some mileage. - Been frequently washed in automatic car washes, particularly "touchless" car washes. This distortion may look like a subtle orange peel pattern, or may look like a drip or sag etched into the surface of the glass. Some car wash solutions contain a buffered solution of hydrofluoric acid which is used to clean the glass. This should not cause a problem if used in the correct concentration. However, if not used correctly, hydrofluoric acid will attack the glass, and over time, will cause visual distortion in the outer surface of the glass which cannot be removed by scraping or polishing. If this condition is suspected, look at the area of the windshield under the wipers or below the belt seal on the side glass. The area of the glass below the wipers or belt seal will not be affected and what looks like a drip or sag may be apparent at the edge of the wiper or belt seal. You may also see a line on the glass where the wiper blade or the belt seal contacts the glass. Important The repair will require replacing the affected glass and is not a result of a defect in material or workmanship. Therefore, is not covered by New Vehicle Warranty.

Wiper Concerns Most concerns about windshield wiper performance are the result of dirty wiper blades, damaged wiper blades, or worn out blades that are continuing to be used beyond their useful life. Depending on environmental conditions, wiper blades can have dramatic differences in lifespan. Here are some tips and guidelines to maximize wiper performance to avoid damage to the blades, and to avoid unnecessary replacements. Many wiper blades are being replaced under warranty with reviews showing there is nothing wrong with the returned blades other than a build-up of dirt. Additionally, advise the customer to review the information in their Owner Manual. Inspection and Cleaning Scheduled Maintenance - Inspect your wipers rubber blades every 4-6 months or 12,000 km (7,500 mi) for wear, cracking or contamination. - Clean the windshield and the rubber wiper blades (using the procedure below) if the blades are not clearing the glass satisfactorily. If this does not correct the problem, then replace the rubber elements. Cleaning Procedure Important Avoid getting windshield washer fluid on your hands. Wear rubber gloves or avoid direct contact with washer fluid. Important Do not use gasoline, kerosene, or petroleum based products to clean wiper blades. - Clean the rubber blades using a lint free cloth or paper towel soaked with windshield washer fluid or a mild detergent. You should see significant amounts of dirt being removed on the cloth. - Be sure to wash the windshield thoroughly when you clean the blades. Bugs, road grime, sap and a buildup of car wash/wax treatments may additionally cause wiper streaking. Tip For a larger scale buildup on the windshield, use a non-abrasive cleaner such as Bon-Ami* (www.faultless.com) cleanser with a wet sponge, being sure to use plenty of water to avoid scratching the glass. Flush the surface and body panels completely. Tip For day-to-day exterior glass cleaning and to maintain a streak free appearance, suggest Vehicle Care Glass Cleaner, P/N 88862560 (in Canada, 992727). This product is an easy to use foaming cleaner that quickly removes dirt and grime from glass surfaces. Tip Interior glass should be cleaned with plain, clean water to eliminate any film or haze on the window and help prevent fogging, a major customer dissatisfier. Refer to Corporate Bulletin Number 03-00-89-006D for more information. The New Vehicle Pre-Delivery Inspection form also recommends using plain water to clean interior glass. *"We believe this material to be reliable.

Some of these you can control and others are environmental concerns. - Extremely dusty areas (such as driving on dirt roads) may cause the wipers rubber edge to wear quickly and unevenly. - Sand and salt used on roads for increasing winter traction and ice control will cause the wiper blades to wear quicker. Areas with significant snowfall require more frequent blade replacements. - Heat and time may cause the rubber blades to take a "permanent set" resulting in the rubber not flexing and turning over uniformly. This condition may result in streaking and/or unwiped areas. - Rubber blades are easily cut or torn when using ice scrapers. Likewise pulling blades up off a frozen windshield can tear the rubber. Exercise caution when clearing ice and snow. - Using your wipers to "wear through" frost and ice, instead of allowing the defrosters to melt the ice, can dull, nick or tear the rubber blades. - Banging wipers on the glass to remove ice and snow may cause the blade to bend, dislodging the rubber and causing potential scratching of the windshield. - Ice can form in the pin joints of the wipers, which can cause streaking and unwiped areas. To remove ice from pin joints, compress the blade and rubber edge with your hand to loosen the frozen joints. Consider using Winter Blades that have a rubber cover to avoid this condition. Note GM does not recommend the use of any spray on/wipe on windshield treatments or washer fluid additives. The variation in friction that results on the glass from the use of these products causes wipers to chatter and have premature wear.

SIR circuits, all such circuits are indicated on circuit diagrams with the SIR symbol. - NOTE: Refer to OBD II Symbol Description Notice. OBD II circuits, all such circuits are indicated on circuit diagrams with the OBD II symbol. Always check for aftermarket accessories (non-OEM) as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify that these add-on accessories are not the cause of the problems. Possible causes of vehicle problems related to aftermarket accessories include: - Power feeds connected to points other than the battery - Antenna location - Transceiver wiring located too close to vehicle electronic modules or wiring - Poor shielding or poor connectors on antenna feed line - Check for recent service bulletins detailing installation guidelines for aftermarket accessories. Circuit Protection - Circuit Breakers CIRCUIT PROTECTION - CIRCUIT BREAKERS A circuit breaker is a protective device that is designed to open the circuit when a current load is in excess of the rated breaker capacity. If there is a short or other type of overload condition in the circuit, the excessive current will open the circuit between the circuit breaker terminals. Two types of circuit breakers are used. Circuit Breaker This type opens when excessive current passes through it for a period of time. It closes again after a few seconds, and if the cause of the high current is still present, it will open again. The circuit breaker will continue to cycle open and closed until the condition causing the high current is removed. Positive Temperature Coefficient (PTC) Circuit Breaker This type greatly increases its resistance when excessive current passes through it. The excessive current heats the PTC device, as the device heats its Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17779 resistance increases. Eventually the resistance gets so high that the circuit is effectively open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the voltage is removed the circuit breaker will re-close within a second or 2. Circuit Protection - Fuses CIRCUIT PROTECTION - FUSES Fuse Types The fuse is the most common method of an automotive wiring circuit protection. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are an one time protection device and must be replaced each time the circuit is overloaded. To determine if a fuse is open, remove the suspected fuse and examine the element in the fuse for an open (2). If not broken (1), also check for continuity using a DMM or a continuity tester. If the element is open or continuity is suspect, replace the fuse with one of equal current rating. Circuit Protection - Fusible Links CIRCUIT PROTECTION - FUSIBLE LINKS Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17780 electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size. Repairing a Fusible Link IMPORTANT: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection. Refer to Splicing Copper Wire Using Splice Clips. Inducing Intermittent Fault Conditions INDUCING INTERMITTENT FAULT CONDITIONS TOOLS REQUIRED J 25070 Heat Gun Many intermittent open or shorted circuits are affected by harness/connector movement that is caused by vibration, engine torque, bumps/rough pavement, etc. In order to duplicate the customer's concern, it may be necessary to manipulate the wiring harness if the malfunction appears to be vibration related. Manipulation of a circuit can consist of a wide variety of actions, including: Wiggling the harness - Disconnecting a connector and reconnecting - Stressing the mechanical connection of a connector - Pulling on the harness or wire in order to identify a separation/break inside the insulation - Relocating a harness or wires All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to the control module. The snapshot option would be appropriate here. Refer to Scan Tool Snapshot Procedure. Another option is, with the component commanded ON and OFF by the scan tool, move related connectors and wiring and observe the component operation. With the engine running, move related connectors and wiring while monitoring engine operation. If harness or connector movement affects the data displayed, component/system operation, or engine operation, inspect and repair the harness/connections as necessary. You may need to load the vehicle in order to duplicate the concern. This may require the use of weights, floorjacks, jackstands, frame machines, etc. In these cases you are attempting to duplicate the concern by manipulating the suspension or frame. This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection. A DMM set to Peak Min/Max mode and connected to the suspect circuit while testing can yield desirable results. Refer to Testing for Electrical Intermittents. Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well. There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness. Such conditions would include high moisture conditions, along with exceptionally high or low temperatures. The following discusses how to expose the circuit to these kinds of conditions. SALT WATER SPRAY Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt. By mixing table salt with water in sufficient quantities, you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture. Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this mixture. This mixture is sufficient to enhance the water's own conductivity. This may cause the circuit to fail more easily when sprayed. Once the mixture is completed, spray the suspect area liberally with the solution. Then, while monitoring either a scan tool or DMM, manipulate the harness as discussed previously. HIGH TEMPERATURE CONDITIONS If the complaint tends to be heat related, you can simulate the condition using the J 25070. Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition. The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however. LOW TEMPERATURE CONDITIONS Depending on the nature of the fault condition, placing a fan in front of the vehicle while the vehicle is in the shade can have the desired effect. If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable of producing air stream temperatures down to -18°C (0°F) from one end and +71°C (160°F) from the other. This is ideally suited for localized Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17781 cooling needs. Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern. DUPLICATING FAILURE CONDITIONS - If none of the previous tests are successful, attempt to duplicate and/or capture the failure conditions. - Freeze Frame/Failure Records data, where applicable, contains the conditions that were present when the DTC set. 1. Review and record Freeze Frame/Failure Records data. 2. Clear the DTCs using the scan tool. 3. Turn the key to OFF and wait 15 seconds. 4. Operate the vehicle under the same conditions that were noted in Freeze Frame/Failure Records data, as closely as possible. The vehicle must also be operating within the Conditions for Running the DTC. Refer to Conditions for Running the DTC in the supporting text if a DTC is being diagnosed. 5. Monitor DTC Status for the DTC being tested. The scan tool will indicate Ran, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed. - An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the concern occurs, may help you locate the concern. Measuring Frequency MEASURING FREQUENCY NOTE: Refer to Test Probe NOTE. The following procedure determines the frequency of a signal. IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range. 1. Apply power to the circuit. 2. Set the rotary dial of the DMM to the V (AC) position. 3. Connect the positive lead of the DMM to the circuit to be tested. 4. Connect the negative lead of the DMM to a good ground. 5. Press the Hz button on the DMM. 6. The DMM will display the frequency measured. Measuring Voltage MEASURING VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure measures the voltage at a selected point in a circuit. 1. Disconnect the electrical harness connector for the circuit being tested, if necessary. 2. Enable the circuit and/or system being tested. Use the following methods: - Turn ON the ignition, with the engine OFF. - Turn ON the engine. - Turn ON the circuit and/or system with a scan tool in Output Controls. - Turn ON the switch for the circuit and/or system being tested. 3. Select the V (AC) or V (DC) position on the DMM. 4. Connect the positive lead of the DMM to the point of the circuit to be tested. 5. Connect the negative lead of the DMM to a good ground. 6. The DMM displays the voltage measured at that point. Measuring Voltage Drop MEASURING VOLTAGE DROP NOTE: Refer to Test Probe NOTE. The following procedure determines the difference in voltage potential between 2 points. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17782 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one point of the circuit to be tested. 3. Connect the negative lead of the DMM to the other point of the circuit. 4. Operate the circuit. 5. The DMM displays the difference in voltage between the 2 points. Probing Electrical Connectors PROBING ELECTRICAL CONNECTORS IMPORTANT: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals. Frontprobe Disconnect the connector and probe the terminals from the mating side (front) of the connector. IMPORTANT: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The proper adapter for 0.64 terminals is the J 35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis. NOTE Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors: Backprobe Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17783 IMPORTANT: Backprobe connector terminals only when specifically required in diagnostic procedures. - Do not backprobe a sealed (Weather Pack(R)) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. - Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. - After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact. Do not disconnect the connector and probe the terminals from the harness side (back) of the connector. Scan Tool Snapshot Procedure SCAN TOOL SNAPSHOT PROCEDURE Snapshot is a recording of what a control module on the vehicle was receiving for information while the snapshot is being made. A snapshot may be used to analyze the data during the time a vehicle condition is current. This allows you to concentrate on making the condition occur, rather than trying to view all the data in anticipation of the fault. The snapshot contains information around a trigger point that you have determined. Only a single data list may be recorded in each snapshot. The Scan Tool has the ability to store 2 snapshots. The ability to record 2 snapshots allows comparing hot versus cold and good versus bad vehicle scenarios. The snapshots are stored on a first-in, first-out basis. If a third snapshot is taken, the first snapshot stored in the memory will be lost. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17784 Snapshots can be 1 of 2 types: - Snapshot - taken from the Snapshot menu choice - Quick Snapshot - taken from the Data Display soft key choice, does not contain DTC information When a snapshot is taken, it is recorded on the memory card and may contain as many as 1200 frames of information. Because the snapshot is recorded onto the memory card, snapshots are not lost if the Scan Tool is powered down. The snapshot replay screen has a plot soft key that can be of great value for intermittent diagnosis. The snapshot plot feature can help you to quickly determine if a sensor is outside of its expected values by plotting 3 parameters at a time. The data will be displayed both graphically and numerically showing the minimum and maximum values for all frames captured. This is helpful, especially if the fault occurs only once and does not set a DTC. Testing for a Short to Voltage TESTING FOR A SHORT TO VOLTAGE NOTE: Refer to Test Probe Notice. The following procedure tests for a short to voltage in a circuit. 1. Set the rotary dial of the DMM to the V (DC) position. 2. Connect the positive lead of the DMM to one end of the circuit to be tested. 3. Connect the negative lead of the DMM to a good ground. 4. Turn ON the ignition and operate all accessories. 5. If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit. Testing for Continuity TESTING FOR CONTINUITY NOTE: Refer to Test Probe NOTE. The following procedures verify good continuity in a circuit. With a DMM 1. Set the rotary dial of the DMM to the ohm position. 2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit. 3. Disconnect the load. 4. Press the MIN MAX button on the DMM. 5. Connect one lead of the DMM to one end of the circuit to be tested. 6. Connect the other lead of the DMM to the other end of the circuit. 7. If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity. With a Test Lamp IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits. 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to one end of the circuit to be tested. 4. Connect the other lead of the test lamp to battery positive voltage. 5. Connect the other end of the circuit to ground. 6. If the test lamp illuminates (full intensity), then the circuit has good continuity. Testing for Electrical Intermittents TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment. - Testing for Short to Ground - Testing for Continuity - Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200. The J 39200 will generate an audible tone when a change is detected. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17785 IMPORTANT: The J 39200 must be used in order to perform the following procedure since the J 39200 can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200. The J 39200 displays 100 ms RECORD and emits an audible tone (beep). IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change. 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent Fault Conditions. 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. - If the variation between the recorded MIN and MAX voltage values is 1 volt or greater an intermittent open or high resistance condition exists. Repair the condition as necessary. - If the variation between the recorded MIN and MAX voltage values is less than 1 volt an intermittent open or high resistance condition does not exist. Testing for Intermittent Conditions and Poor Connections TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS TOOLS REQUIRED - J 35616 GM-Approved Terminal Test Kit - J-38125 Terminal Repair Kit When the condition is not currently present, but is indicated in DTC history, the cause may be intermittent. An intermittent may also be the cause when there is a customer complaint, but the symptom cannot be duplicated. Refer to the Symptom Table of the system that is suspect of causing the condition before trying to locate an intermittent condition. Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items: Wiring broken inside the insulation - Poor connection between the male and female terminal at a connector - Poor terminal to wire connection-Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc. - Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits. - Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle. - Wiring that comes in contact with hot or exhaust components - Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern. - Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions. - Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation. TESTING FOR PROPER TERMINAL CONTACT It is important to test terminal contact at the component and any inline connectors before replacing a suspect component. Mating terminals must be inspected to ensure good terminal contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation. Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit. Deformation is caused by probing the mating side of a connector terminal without the proper adapter. Always use the J 35616 when probing connectors. Other causes of terminal deformation are improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal contact tang, can result in poor terminal contact causing an open or intermittently open circuit. TESTING FOR PROPER TERMINAL CONTACT IN BUSSED ELECTRICAL CENTERS (BEC) It is very important to use the correct test adapter when testing for proper terminal contact of fuses and relays in a bussed electrical center (BEC). Use J-35616-35 to test for proper terminal contact. Failure to use J-35616-35 can result in improper diagnosis of the BEC. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17786 Follow the procedure below in order to test terminal contact: 1. Separate the connector halves. 2. Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety: terminals, seals, and connector body. 3. Using an equivalent male terminal from the J-38125, test that the retention force is significantly different between a good terminal and a suspect terminal. Replace the female terminal in question. FLAT WIRE (DOCK AND LOCK) CONNECTORS There are no serviceable parts for flat wire (dock and lock) connectors on the harness side or the component side. Follow the procedure below in order to test terminal contact: 1. Remove the component in question. 2. Visually inspect each side of the connector for signs of contamination. Avoid touching either side of the connector as oil from your skin may be a source of contamination as well. 3. Visually inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact. Visually inspect the component side connector to ensure that all of the terminals are uniform and free of damage or deformation. 4. Insert the appropriate adapter from the on the flat wire harness connector in order to test the circuit in question. CONTROL MODULE/COMPONENT VOLTAGE AND GROUNDS Poor voltage or ground connections can cause widely varying symptoms. Test all control module voltage supply circuits. Many vehicles have multiple circuits supplying voltage to a control module. Other components in the system may have separate voltage supply circuits that may also need to be tested. Inspect connections at the module/component connectors, fuses, and any intermediate connections between the voltage source and the module/component. A test lamp or a DMM may indicate that voltage is present, but neither tests the ability of the circuit to carry sufficient current. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Power Distribution Schematics. - Test all control module ground and system ground circuits. The control module may have multiple ground circuits. Other components in the system may have separate grounds that may also need to be tested. Inspect grounds for clean and tight connections at the grounding point. Inspect the connections at the component and in splice packs, where applicable. Ensure that the circuit can carry the current necessary to operate the component. Refer to Circuit Testing and Ground Distribution Schematics. TEMPERATURE SENSITIVITY - An intermittent condition may occur when a component/connection reaches normal operating temperature. The condition may occur only when the component/connection is cold, or only when the component/connection is hot. - Freeze Frame, Failure Records, Snapshot, or Vehicle Data Recorder data may help with this type of intermittent condition, where applicable. - If the intermittent is related to heat, review the data for a relationship with the following: High ambient temperatures - Underhood/engine generated heat - Circuit generated heat due to a poor connection, or high electrical load - Higher than normal load conditions, towing, etc. - If the intermittent is related to cold, review the data for the following: Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Inspect for water intrusion. - The condition only occurs on a cold start. - The condition goes away when the vehicle warms up. - Information from the customer may help to determine if the trouble follows a pattern that is temperature related. - If temperature is suspected of causing an intermittent fault condition, attempt to duplicate the condition. Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required. ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTRICAL NOISE Some electrical components/circuits are sensitive to electromagnetic interference (EMI) or other types of electrical noise. Inspect for the following conditions: A misrouted harness that is too close to high voltage/high current devices such as secondary ignition components, motors, generator etc-These components may induce electrical noise on a circuit that could interfere with normal circuit operation. - Electrical system interference caused by a malfunctioning relay, or a control module driven solenoid or switch-These conditions can cause a sharp electrical surge. Normally, the condition will occur when the malfunctioning component is operating. - Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems, cell phones, etc-These accessories may lead to interference while in use, but do not fail when the accessories are not in use. - Test for an open diode across the A/C compressor clutch and for other open diodes. Some relays may contain a clamping diode. - The generator may be allowing AC noise into the electrical system. INCORRECT CONTROL MODULE - There are only a few situations where reprogramming a control module is appropriate: A new service control module is installed. - A control module from another vehicle is installed. - Revised software/calibration files have been released for this vehicle. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17787 - IMPORTANT: DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern. Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning Testing for Short to Ground TESTING FOR SHORT TO GROUND NOTE: Refer to Test Probe NOTE. The following procedures test for a short to ground in a circuit. With a DMM 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Set the rotary dial of the DMM to the ohm position. 4. Connect one lead of the DMM to one end of the circuit to be tested. 5. Connect the other lead of the DMM to a good ground. 6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit. With a Test Lamp 1. Remove the power feed (i.e. fuse, control module) from the suspect circuit. 2. Disconnect the load. 3. Connect one lead of the test lamp to battery positive voltage. 4. Connect the other lead of the test lamp to one end of the circuit to be tested. 5. If the test lamp illuminates, there is a short to ground in the circuit. Fuse Powering Several Loads 1. Review the system schematic and locate the fuse that is open. 2. Open the first connector or switch leading from the fuse to each load. 3. Connect a DMM across the fuse terminals (be sure that the fuse is powered). - When the DMM displays voltage the short is in the wiring leading to the first connector or switch. - If the DMM does not display voltage 4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted. Troubleshooting with a Digital Multimeter TROUBLESHOOTING WITH A DIGITAL MULTIMETER NOTE: Refer to Test Probe NOTE. IMPORTANT: Circuits which include any solid state control modules, such as the powertrain control module (PCM), should only be tested with a 10 megohm or higher impedance digital multimeter such as the J 39200 Digital Multimeter (DMM). The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present. The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit. Low resistance in a circuit means good continuity. IMPORTANT: Disconnect the power feed from the suspect circuit when measuring resistance with a DMM. This prevents incorrect readings. DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading. Diodes and solid state components in a circuit can cause a DMM to display a false reading. To find out if a component is affecting a measurement take a reading once, then reverse the leads and take a second reading. If the readings differ the solid state component is affecting the measurement. Following are examples of the various methods of connecting the DMM to the circuit to be tested: Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving. Refer to Probing Electrical Connectors. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17788 - Disconnect the harness at both ends of the suspected circuit where it connects either to a component or to other harnesses. - If the system that is being diagnosed has a specified pinout or breakout box, it may be used in order to simplify connecting the DMM to the circuit or for testing multiple circuits quickly. Troubleshooting With A Test Lamp TROUBLESHOOTING WITH A TEST LAMP TOOLS REQUIRED J 35616-200 Test Light - Probe Kit NOTE: Refer to Test Probe NOTE. A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminage even though voltage is present. The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads. To properly operate this tool use the following procedures. When testing for voltage: 1. Attach one lead to ground. 2. Touch the other lead to various points along the circuit where voltage should be present. 3. When the bulb illuminates, there is voltage at the point being tested. When testing for ground: 1. Attach one lead to battery positive voltage. 2. Touch the other lead to various points along the circuit where ground should be present. 3. When the bulb illuminates, there is ground at the point being tested. Using Connector Test Adapters USING CONNECTOR TEST ADAPTERS NOTE: Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals. When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the correct size for the connector terminal. Do not visually choose the terminal test adapter because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the connector end view for terminal size.

Delphi Connectors (Micro-Pack 100W) DELPHI CONNECTORS (MICRO-PACK 100W) TOOLS REQUIRED J-38125 Terminal Repair Kit TERMINAL REMOVAL PROCEDURE There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also. The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17807 IMPORTANT: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area. Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide. 1. Disconnect the connector from the component. 2. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such.

If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector. TERMINAL REPAIR PROCEDURE The Micro-Pack 100W connectors have small terminals that are difficult to handle and hold when crimping. In order to aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-101 (W jaw) crimping tool was developed to crimp Micro-Pack 100W terminals. The J 38125-101 (W jaw) crimping tool has a terminal holding block that will hold the terminal in place while the terminal is being crimped. After the terminal is removed from the connector perform the following procedure in order to repair Micro-Pack 100 terminals. 1. Cut the wire as close to the terminal as possible. 2. IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining wire is long enough to reach the connector without putting a strain on the wire. If the wire is not long enough, splice a small length of the same gage wire to the existing wire, then crimp the new terminal on the added wire. Strip 5 mm (3/16 in) of insulation from the wire.

GMLAN Wiring Repairs GMLAN WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals. The tool kit J-38125 contains the following items in order to repair the GMLAN wiring: DuraSeal splice sleeves - A wire stripping tool - J 38125-8 Crimping Tool (GM P/N 12085115) - J 38125-5 Ultra Torch Special Tool (GM P/N 12085116) The DuraSeal splice sleeves have the following 2 critical features: A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside. - A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits. The J-38125 also serves as a generic terminal repair kit. The kit contains the following items: A large sampling of common electrical terminals - The correct tools in order to attach the terminals to the wires - The correct tools in order to remove the terminals from the connectors GMLAN REPAIRS IMPORTANT: When making a repair to any GMLAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed. GMLAN has 2 types of networks, low speed and high speed. Low speed GMLAN has a single wire and works at slow speeds. High speed GMLAN has 2 wires in a twisted pair and works at higher speeds. For more information on GMLAN, refer to Data Link Communications Description and Operation. GMLAN CONNECTOR TERMINAL REPAIR IMPORTANT: A service terminal can be used to replace damaged connector terminals for both high speed and low speed GMLAN systems. When making a connector terminal repair on a GMLAN high speed system with twisted pair wires, do not untwist the wires more than necessary to make the repair. The terminals in the GMLAN system are made of a special metal. This metal provides the necessary contact integrity for the sensitive, low energy circuits. These terminals are available in the J-38125. If the individual terminals are damaged on any GMLAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure. GMLAN WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17852 If a wire is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm, etc.). Use the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the sealed splice. 1. IMPORTANT: You must perform the following procedures in the listed order. Repeat the procedure if any wire strands are damaged. You must obtain a clean strip with all of the wire strands intact. Open the harness by removing any tape: - Use a sewing seam ripper (available from sewing supply stores) in order to cut open the harness in order to avoid wire insulation damage. - Use the DuraSeal splice sleeves on all types of insulation except coaxial. - Do not use the DuraSeal splice sleeve to form a splice with more than 2 wires coming together. 2. Cut as little wire off the harness as possible. You may need the extra length of wire in order to change the location of a splice.Adjust splice locations so that each splice is at least 40 mm (1.5 in) away from the other splices, harness branches, or connectors. 3. Strip the insulation: - When adding a length of wire to the existing harness, use the same size wire as the original wire. - Perform one of the following items in order to find the correct wire size: Find the wire on the schematic and convert the metric size to the equivalent American wire gage (AWG) size. - Use an AWG wire gage. - If you are unsure of the wire size, begin with the largest opening in the wire stripper and work down until achieving a clean strip of the insulation. - Strip approximately 7.5 mm (0.313 in) of insulation from each wire to be spliced. - Do not nick or cut any of the strands. Inspect the stripped wire for nicks or cut strands. - If the wire is damaged, repeat this procedure after removing the damaged section. 4. Select the proper DuraSeal splice sleeve according to the wire size. Refer to the above table at the beginning of the repair procedure for the color coding of the DuraSeal splice sleeves and the crimp tool nests. 5. Use the Splice Crimp Tool from the J-38125 in order to position the DuraSeal splice sleeve in the proper color nest of the Splice Crimp Tool. The crimp tool has three nests, 1 is for the salmon and green splice sleeve, 2 is for the blue splice sleeve, and 3 is for the yellow splice sleeve. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17853 6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest. 7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop. 8. Tightly close the handles of the crimp tool until the crimper handles open when released.The crimper handles will not open until you apply the proper amount of pressure to the splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice. 9. Using the heat torch, apply heat to the crimped area of the barrel. 10. Start in the middle and gradually move the heat barrel to the open ends of the tubing: - The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Heated Oxygen Sensor Wiring Repairs HEATED OXYGEN SENSOR WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit NOTE:Do not solder repairs under any circumstances as this could result in the air reference being obstructed. If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance. The following guidelines should be used when servicing the heated oxygen sensor: Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. - Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire. - Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17854 - To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector. The engine harness may be repaired using the J-38125. High Temperature Wiring Repairs HIGH TEMPERATURE WIRING REPAIRS TOOLS REQUIRED J-38125 Terminal Repair Kit HIGH TEMPERATURE WIRING Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following: Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire. - Replace any heat shielding that is removed. - Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit). - After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source. IDENTIFYING HIGH TEMPERATURE WIRING Wiring that is exposed to high temperature, 135°C (275°F) or higher, for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair. Obvious areas of consideration would be any area located near the exhaust manifolds, catalytic converter, and exhaust pipes. The J-38125 contains much of the material you will need to perform repairs on areas exposed to high heat. The kit contains the following items: DuraSeal splice sleeves to crimp and seal connections - High temperature SCT1 shrink tubing to protect the splice sleeves - A large sampling of common electrical terminals - The correct crimp tool to attach the terminals to the wires - The correct tools to remove the terminals from the connectors The J-38125 does not contain wire that is suitable to high temperature exposure. Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gage size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair. HIGH TEMPERATURE WIRE REPAIR IMPORTANT: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity. If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire rated at 150°C (302°F) continuous temperature rating of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.).

This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original (except fusible link). - The wire insulation must have the same or higher temperature rating. Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced. 5. Select the proper clip to secure the splice. Follow the instructions in the J-38125 in order to determine the proper clip size crimp tool and anvil. 6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger. 7. Center the splice clip (2) over the stripped wires (1) and hold the clip in place. - Ensure that the wires extend beyond the clip in each direction. - Ensure that no insulation is caught under the clip. 8. Center the crimp tool over the splice clip and wires. 9. Apply steady pressure until the crimp tool closes.Ensure that no strands of wire are cut. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17861 10. Crimp the splice on each end (2). 11. Apply 60/40 rosin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment. 12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires. 13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to cover the first piece of tape. Splicing Copper Wire Using Splice Sleeves SPLICING COPPER WIRE USING SPLICE SLEEVES TOOLS REQUIRED J-38125 Terminal Repair Kit IMPORTANT: Use only duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection. Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17862 Use duraseal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial. Use duraseal splice sleeves where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using duraseal splice sleeves. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the desired wire. 2. Cut the wire. - Cut as little wire off the harness as possible. - Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches, and connectors. This helps prevent moisture from bridging adjacent splices and causing damage. 3. Select the proper size and type of wire. - The wire must be of equal or greater size than the original. - The wires insulation must have the same or higher temperature rating (4). Use general purpose insulation for areas that are not subject to high temperatures. - Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected. IMPORTANT: Use cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC. - Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact. 4. Strip the insulation. - Select the correct size opening in the wire stripper or work down from the largest size. - Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1). 5. Select the proper duraseal splice sleeve (2) and the required crimp nest tool. Refer to the Crimp and Seal Splice Table. 6. Place the duraseal splice sleeve in the J-38125-8 (GM P/N 12085115) crimp tool nest so that the crimp falls at point 1 on the splice. 7. Close the hand crimper handles slightly in order to hold the duraseal splice sleeve firmly in the proper crimp tool nest. 8. Insert the wires into the duraseal splice sleeve until the wire hits the barrel stop. The splice sleeve has a stop in the middle of the barrel in order to prevent the wire from passing through the splice (3). 9. Close the handles of the J-38125-8 (GM P/N 12085115), until the crimper handles open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. 10. Shrink the insulation around the splice. - Using the heat torch, apply heat to the crimped area of the barrel. - Gradually move the heat barrel to the open end of the tubing. The tubing will shrink completely as the heat is moved along the insulation. - A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved. Splicing Inline Harness Diodes Chevrolet Equinox Fwd Workshop Manual (V6-3.4L (2007)) Chevrolet Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 17863 SPLICING INLINE HARNESS DIODES Many vehicle electrical systems use a diode to isolate circuits and protect the components from voltage spikes. When installing a new diode use the following procedure. 1. Open the harness. - If the harness is taped, remove the tape. - To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness. - If the harness has a black plastic conduit, pull out the diode. 2. If the diode is taped to the harness, remove all of the tape. 3. Check and record the current flow direction and orientation of diode. 4. Remove the inoperative diode from the harness with a suitable soldering tool. IMPORTANT: If the diode is located next to a connector terminal remove the terminal(s) from the connector to prevent damage from the soldering tool. 5. Carefully strip away a section of insulation next to the old soldered portion of the wire(s). Do not remove any more than is needed to attach the new diode. 6. Check current flow direction of the new diode, being sure to install the diode with correct bias. Reference the appropriate service manual wiring schematic to obtain the correct diode installation position. 7. Attach the new diode to the wire(s) using 60/40 rosin core solder. Before soldering attach some heat sinks (aluminum alligator clips) across the diode wire ends to protect the diode from excessive heat. Follow the manufacturer's instruction for the soldering equipment. 8. Reinstall terminal(s) into the connector body if previously removed. 9. IMPORTANT: To prevent shorts to ground and water intrusion, completely cover all exposed wire and diode attachment points with tape. Tape the diode to the harness or connector using electrical tape. Splicing Twisted or Shielded Cable SPLICING TWISTED OR SHIELDED CABLE Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose(R) speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable. 1. Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape. 2. Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made. 3. Prepare the splice. Untwist the conductors and follow the splicing instructions for copper wire. Staggering the splices by 65 mm (2.5 in) is recommended.
