The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and
controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics.
- Monitors the RWAL brake system for proper operation.
- Controls the RWAL valve solenoids.
NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be
programed into the new CAB.
SYSTEM SELF-TEST
When the ignition switch is turned-on the microprocessor RAM and ROM are tested. If an error
occurs during the test a Diagnostic Trouble Code (DTC) will be set into the RAM memory. However
it is possible the DTC will not be stored in memory if the error has occurred in the RAM module
were the DTC's are stored. Also it is possible a DTC may not be stored if the error has occurred in
the ROM which signals the RAM to store the DTC.
CAB INPUTS
The CAB continuously monitors the speed of the differential ring gear by monitoring signals
generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency when it
recognizes the ring gear decelerating too rapidly. The CAB monitors the following inputs to
determine when a wheel locking tendency may exists: -
Rear Wheel Speed Sensor
- Brake Lamp Switch
- Brake Warning Lamp Switch
- Reset Switch
- 4WD Switch (If equipped)
CAB OUTPUTS
The CAB controls the following outputs for antilock braking and brake warning information: RWAL Valve

SYSTEM OPERATION
Front
The front blower motor relay is a International Standards Organization (ISO)-type relay. The relay
is a electromechanical device that switches battery current from a fuse in the Power Distribution
Center (PDC) directly to the blower motor. The relay is energized when the relay coil is provided a
voltage signal by the ignition switch. This arrangement reduces the amount of battery current that
must flow through the ignition switch.
The blower motor relay control circuit is protected by a fuse located in the junction block. When the
relay is de-energized, the blower motor receives no battery current. See Blower Motor Relay in the
Diagnosis and Testing for more information.
The front blower motor relay is located in the PDC in the engine compartment. Refer to the PDC
label for blower motor relay identification and location.
The blower motor relay cannot be repaired and, if faulty or damaged, it must be replaced.

The high speed blower motor relay is energized when the relay coil is provided a ground signal by
the blower motor switch, and a battery feed from the ignition switch. When the relay is
de-energized, the rear blower motor ground feed is routed through the rear blower motor switch
and the blower motor resistor. See High Speed Blower Motor Relay in the Diagnosis and Testing
for more information.
The rear high speed blower motor relay is located in a connector that is secured to the back of the
rear heater-A/C unit housing in the passenger compartment. See High Speed Blower Motor Relay
Rear in the Removal and Installation for rear high speed blower motor relay identification and
location.
The rear high speed blower motor relay cannot be repaired and, if faulty or damaged, it must be
replaced.

The blower motor relays used for the front heater-only or heater-A/C systems and for the optional
rear heater-A/C unit can be tested in the same manner. The front blower motor relay is located in
the Power Distribution Center (PDC). The rear blower motor relay is located in a connector that is
attached to the back of the rear heater-A/C unit. See Blower Motor Relay in the Removal and
Installation for the procedures to remove the relay, to perform the following tests:
1. A relay in the de-energized position should have continuity between terminals 87A and 30, and
no continuity between terminals 87 and 30. If OK,
go to Step 3. If not OK, replace the faulty relay
2. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 4. If not OK, replace the faulty relay. 3. Connect a battery to terminals 85 and 86. There
should now be continuity between terminals 30 and 87, and no continuity between terminals 87A
and 30. If OK, see Relay Circuit Test in the Diagnosis and Testing. If not OK, replace the faulty
relay.

Compressor Clutch Relay: Description and Operation
SYSTEM OPERATION
The compressor clutch relay is a International Standards Organization (ISO) micro-relay The
terminal designations and functions are the same as a conventional ISO relay. However, the
micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay
case dimensions are smaller than those of the conventional ISO relay
The compressor clutch relay is a electromechanical device that switches battery current to the
compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the
relay. The PCM responds to inputs from the heater-A/C mode control switch, the low pressure
cut-off switch, the high pressure cut-off switch, and the fin sensing cycling clutch switch. See
Compressor Clutch Relay in the Diagnosis and Testing for more information.
The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine
compartment. Refer to the PDC label for relay identification and location.
The compressor clutch relay cannot be repaired and, if faulty or damaged, it must be replaced.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.
- ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE
CLOTHING.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Audible Warning Device Control Module: Description and Operation
SYSTEM OPERATION
A Central Timer Module (CTM) is used on this vehicle when it is equipped with the optional Vehicle
Theft Security System (VTSS). In addition to serving as the security system module, the CTM
combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated
entry module, and a Remote Keyless Entry (RKE) module in a single unit.
The CTM is also able to control and integrate many of the additional electronic functions and
features included on models with this option. The CTM contains a central processing unit and
interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus
network. The CCD data bus network allows the sharing of sensor information. This helps to reduce
wire harness complexity, reduce internal controller hardware, and reduce component sensor
current loads. At the same time, this system provides increased reliability, enhanced diagnostics,
and allows the addition of many new feature capabilities.
The horn relay is one of the outputs that the CTM can control. The CTM is programmed to energize
or de-energize the horn relay in response to certain inputs from the Vehicle Theft Security System
(VTSS) and the Remote Keyless Entry (RKE) system. Refer to Body and Frame/Locks/Power
Locks Systems for more information on the RKE system. Refer to Accessories and Optional
Equipment/Antitheft and Alarm Systems/Vehicle Theft/Security Systems for more information on
the VTSS.
The CTM is mounted under the instrument panel, to the inboard side of the left center instrument
panel support. Refer to Instrument Panel, Gauges and Warning Indicators/Instrument
Panel/Central Timer Module Replacement
For diagnosis of the CTM or the CCD data bus, a DRB scan tool and the proper Diagnostic
Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be
replaced.
The CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless
Entry (RKE) systems. The CTM receives hard wired inputs from the power lock switches, CCD
message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and
coded radio frequency inputs from the RKE transmitters. In response to those and many other
inputs, the internal programming of the CTM sends the proper outputs to control the power lock
motors, the headlamp and horn relays, and the courtesy lamps.
The RKE receiver within the CTM has a memory function to retain the vehicle access codes of at
least one, but no more than four RKE transmitters. The receiver is designed to retain the
transmitter codes in memory, even if the battery is disconnected.
Some of the features and functions of the power lock, illuminated entry and RKE systems made
possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a
power door lock switch if the key is in the ignition and/or the headlamps are on. However, the locks
can still be operated manually, with a key, or energized with the REE transmitter.
- A delay lock feature. With the delay lock feature, if a side or rear door is still open when a lock
request is received by the CTM, the module will automatically cycle all of the power lock motors to
lock five seconds after the doors are closed.
- An enhanced accident response feature will unlock all doors, then prevent the power door lock
system from locking the doors for a predetermined time interval, after receiving a CCD message
from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature
will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if
the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course,
these responses are dependent upon functional battery power and wiring circuitry following the
impact.
- Rolling door locks is a programmable feature of the power lock system. This feature will
automatically lock all of the doors and the liftgate after the vehicle reaches a speed of about 24
kilometers-per- hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is
opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour).
- A programmable feature of the RKE system is the enabling or disabling of the horn chirp following
activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the
horn chirp duration (twenty or forty milliseconds) can be selected.
The CTM is mounted under the instrument panel, to the inboard side of the left center instrument
panel support. Refer to Central Timer Module Replacement.
The programmable features of the CTM can be enabled or disabled using the DRB scan tool as
described in the proper Diagnostic Procedures. For diagnosis of the CTM or the CCD data bus, a
DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be
repaired and, if faulty or damaged, it must be replaced.

hardware, and reduce component sensor current loads. At the same time, this system provides
increased reliability, enhanced diagnostics, and allows the addition of many new feature
capabilities.
One of the features that the CTM supports and controls is the Vehicle Theft Security System
(VTSS). In the VTSS, the CTM receives hard--wired inputs from the door ajar, front door lock
cylinder, and ignition switches. The programming in the CTM allows it to process the information
from these inputs and send control outputs to energize or de-energize the headlamp (or security)
relay, horn relay; and the security lamp. The CTM also sends CCD data bus messages to the
Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS.
The CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry
(RKE) systems, which are integrated into the arming, disarming, and triggering function; of the
VTSS.
The CTM is mounted under the instrument panel, to the inboard side of the left center instrument
panel support. Refer to Instrument Panel, Gauges and Warning Indicators/Audible Warning Device

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.

Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

Instructions > Page 207
Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Body Control Module: Description and Operation System Description and Functional Operation
The body system on the 1998 AB HIGH LINE consists of three modules that communicate over the
CCD bus (Chrysler Collision Detection multiplex system). There are two additional modules, the
Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the
body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for
diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are
performed through the Serial Communication Interface of SCI, the same as previous years. All of
the information about the functioning of all the system is organized, controlled, and communicated
by the CCD bus, which is described in Section 3 (CCD Bus) of this general information section.
Through the CCD bus, information about the operation of vehicle components and circuits is
relayed quickly to the appropriate module(s). All modules receive all the information transmitted on
the bus even though a module may not require all the information to perform it's function. It will only
respond to messages "addressed" to it through a binary coding process. This method of data
transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring
harnesses.

Owner Letter
EMISSIONS RECALL TO REPROGRAM YOUR VEHICLE'S POWERTRAIN CONTROL MODULE
Dear DaimlerChrysler Vehicle Owner:
DaimlerChrysler has determined that some 1998 Dodge Dakota, Durango, Ram Van/Wagon, Ram
Truck, and Jeep(R) Grand Cherokee vehicles, equipped with a V-8 or V-10 engine, may be in
violation of California Emissions Regulations.
The problem is...
The On-Board Diagnostic (OBD) system on your vehicle (identified on the enclosed form) may not
detect evaporative emissions purge system malfunctions as required by California Emissions
Regulations. As a result, the OBD system on your vehicle may not illuminate the "Check Engine"
light if the evaporative emissions purge system malfunctions. This could cause your vehicle to emit
hydrocarbon levels above the limits that were established to protect the public health from the
dangers of air pollution.
Hydrocarbons (unburned fuel) combined with oxides of nitrogen, in the presence of sunlight, can
cause the formation of ozone. These pollutants are the primary components of smog.
What DaimlerChrysler and your dealer will do...
DaimlerChrysler will repair your vehicle free of charge (parts and labor). To do this, your dealer will
reprogram your vehicle's powertrain control module. The work will take about 1/2 hour to complete.
However, additional time may be necessary depending on how dealer appointments are scheduled
and processed.
What you must do...
^ Simply contact your dealer right away to schedule a service appointment.
^ Bring the enclosed Owner Notification form with you to your dealer. It identifies the required
service to the dealer.
If you live in California and don't get this done...
The State of California requires the completion of emission recall repairs prior to vehicle
registration renewal. In addition, the State requires that every vehicle must pass an emission test
(SMOG Check) every two years and before it is sold. Without the free service we are providing,
your vehicle may be more likely to fail this test and require that you make costly repairs.
How the state knows that the recall has been performed...
State of California regulations require DaimlerChrysler to provide the Department of Motor Vehicles
with a record of all vehicles that have not had the recall service performed. If you live in the state of
California and your vehicle is not on this list, the state will know that the recall has been completed.
Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the
recall service is completed. Be sure to save this form since the California Department of Motor
Vehicles may require that you supply it as proof of recall completion.
If you need help...
If you have trouble getting your vehicle repaired, please call the DaimlerChrysler Customer
Assistance Center, toll free, at 1-800-992-1997. A representative will assist you in getting your
vehicle repaired.
In order to ensure your full protection under the emission warranty provisions, it is recommended
that you have your vehicle serviced as soon as possible. Failure to do so could be determined as
lack of proper maintenance of your vehicle.
We are sorry for any inconvenience but trust you understand our interest in clean air and your
continued satisfaction with our products. Thank you for your attention to this important matter.

DISCUSSION:
Whenever any connector on the PCM is disconnected, the ignition switch must be in the "OFF"
position for a minimum of 5 seconds before connector removal.
It has been found under certain key "ON" or momentary key "OFF" conditions, when the black
connector is unplugged, the PCM may attempt to write information to the EEPROM processor
within the PCM. Sometimes this inadvertent write will set the target charging voltage to 0 (zero)
volts. The result will prevent the charging system from charging the battery.
If this occurs, the only correction is PCM replacement.

NO: 18-21-98
GROUP: Vehicle Performance
DATE: Jun. 5, 1998
SUBJECT:
Powertrain Control Module (PCM) Service Caution
MODELS:
1996 - 1998 (AB) Ram Van
1996 - 1998 (AN) Dakota
1996 - 1998 (BR/BE) Ram Truck
1998 (DN) Durango
1997 - 1998 (TJ) Wrangler
1996-1998 (XJ) Cherokee
1996-1998 (ZJ) Grand Cherokee
1996 - 1998 (ZG) Grand Cherokee (European Market)
DISCUSSION:
Whenever any connector on the PCM is disconnected, the ignition switch must be in the "OFF"
position for a minimum of 5 seconds before connector removal.
It has been found under certain key "ON" or momentary key "OFF" conditions, when the black
connector is unplugged, the PCM may attempt to write information to the EEPROM processor
within the PCM. Sometimes this inadvertent write will set the target charging voltage to 0 (zero)
volts. The result will prevent the charging system from charging the battery.
If this occurs, the only correction is PCM replacement.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.
- ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE
CLOTHING.

Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Engine Control Module: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation
Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of
the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check
voltage. Refer to the
appropriate test procedure.

Dodge 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 273
Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Engine Control Module: Description and Operation
SYSTEM OPERATION
Powertrain Control Module (PCM)
The Powertrain Control Module (PCM) is located in the engine compartment. The ignition system is
controlled by the PCM.
NOTE: Base ignition timing by rotation of distributor is not adjustable.
The PCM opens and closes the ignition coil ground circuit to operate the ignition coil. This is done
to adjust ignition timing, both initial (base) and advance, and for changing engine operating
conditions. The amount of electronic spark advance provided by the PCM is determined by five
input factors: engine coolant temperature, engine rpm, intake manifold temperature, manifold
absolute pressure and throttle position.

The relay terminal numbers can be found on the bottom of the relay:
- Terminal number 30 is connected to battery voltage and can be switched or B+ (hot) at all times.
- The center terminal number 87A is connected (a circuit is formed) to terminal 30 in the
de-energized (normally OFF) position.
- Terminal number 87 is connected (a circuit is formed) to terminal 30 in the energized (ON)
position. Terminal number 87 then supplies battery voltage to the component being operated.
- Terminal number 86 is connected to a switched (+) power source.
- Terminal number 85 is grounded by the Powertrain Control Module (PCM).
TESTING
1. Remove relay before testing. 2. Using an ohmmeter, perform a resistance test between
terminals 85 and 86.
- Resistance value (ohms) should be 75 +/- 5 ohms for resistor equipped relays.
3. Connect the ohmmeter between terminals number 87A and 30.
- Continuity should be present at this time.
4. Connect the ohmmeter between terminals number 87 and 30.
- Continuity should not be present at this time.
5. Use a set of jumper wires (16 gauge or smaller).
- Connect one jumper wire between terminal number 85 (on the relay) to the ground side (-) of a 12
volt power source.
6. Attach the other jumper wire to the positive side (+) of a 12V power source.
- Do not connect this jumper wire to relay at this time.
CAUTION: Do not allow the ohmmeter to contact terminals 85 or 86 during these tests. Damage to
ohmmeter may result.
7. Attach the other jumper wire (12V +) to terminal number 86. This will activate the relay.
- Continuity should now be present between terminals number 87 and 30.
- Continuity should not be present between terminals number 87A and 30.
8. Disconnect jumper wires from relay and 12 volt power source.
If continuity or resistance tests did not pass, replace relay.

Air Bag Control Module: Description and Operation
SYSTEM OPERATION
The Airbag Control Module (ACM) is secured to a bracket on the floor panel underneath the driver
side front seat in the passenger compartment of the vehicle. The ACM contains a microprocessor
that contains the airbag system logic, the impact sensor, and an energy storage capacitor. The
ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the
instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag
indicator lamp.
The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical
circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends
messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A
pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration
rate signaled by the impact sensor indicates an impact that is severe enough to require airbag
system protection. When the programmed conditions are met, the ACM sends an electrical signal
to deploy the air-bag system components.
Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that
senses the rate of vehicle deceleration, which provides verification of the direction and severity of
an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit
with the ACM.
The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical
energy to deploy the airbags for up to one second following a battery disconnect or failure during
an impact. The purpose of the capacitor is to provide airbag system protection in a severe
secondary impact, if the initial impact has damaged or disconnected the battery, but was not
severe enough to deploy the airbags.
The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced.

Starter Relay: Description and Operation
SYSTEM OPERATION
The starter relay is a International Standards Organization (ISO) micro-relay. The terminal
designations and functions are the same as a conventional ISO relay However, the micro-relay
terminal orientation (or footprint) is different, the current capacity is lower, and the relay case
dimensions are smaller than those of the conventional ISO relay
The starter relay is a electromechanical device that switches battery current to the pull-in coil of the
starter solenoid when the ignition switch is turned to the Start position. See Starter Relay/Testing
and Inspection/Procedures.
The starter relay is located in the Power Distribution Center (PDC), in the engine compartment.
Refer to the PDC label for relay identification and location.
The starter relay cannot be repaired and, if faulty or damaged, it must be replaced.

SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too
High
OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain
Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and
99Cal14).
MODELS:
**1996** - 1999 (AB) Ram Van
**1996** - 1999 (AN) Dakota
**1996** - 1999 (BR/BE) Ram Truck
1998 - 1999 (DN) Durango
**1997** - 1999 (TJ) Wrangler
**1996** 1999 (XJ) Cherokee
**1996** - 1998 (ZJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC
TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX).
SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble
Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle
operator may experience slower than normal vehicle accelerations because the transmission may
have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode
may last until the vehicle owner cycles the ignition key. The technician may not detect a problem
with the automatic transmission during a diagnostic test or test drive.
The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the
result of a new valve body machining process, which entered into production January 1, 1998. This
condition will occur most often with vehicles that were built between January 1, 1998 and
December 18, 1998.
Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the
transmission assembly is replaced with components built after January 1, 1998.
DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB
III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission
systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record
them on the repair order and repair as necessary before proceeding further with this bulletin. If no
DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF

Wiper Control Module: Description and Operation
SYSTEM OPERATION
Intermittent Wipe Module An intermittent wipe module is used on vehicles that are not equipped
with the optional Vehicle Theft Security System (VTSS). In addition to low and high speed, the
intermittent wipe system has a delay mode. Electronic circuitry within the intermittent wipe module
is used to accomplish the wiper delay mode. The delay time selected by the driver has a range of
from about one-half second to about fourteen seconds.
The driver selects the length of the delay by placing the wiper (multi-function) switch knob in one of
five different intermittent wipe detent positions. One of the detent positions sends a battery voltage
signal to the intermittent wipe module, while the other four positions use resistors to provide
progressively lower voltage signals to the module. If the washer knob is depressed while the wiper
switch is in the Off position, the intermittent wipe module will operate the wiper motor for
approximately two wipes and automatically turn off the motor.
The intermittent wipe module is snap-fit onto a single blade-type mounting bracket located on the
instrument panel reinforcement above the glove box opening. The intermittent wipe module cannot
be repaired and, if faulty or damaged, it must be replaced.

Wiper Relay: Description and Operation
SYSTEM OPERATION
An intermittent wipe relay is used on models that are equipped with the optional Vehicle Theft
Security System (VTSS). The intermittent wipe relay is a International Standards Organization
(ISO) micro-relay. The terminal designations and functions are the same as a conventional ISO
relay. However, the micro-relay terminal orientation (or footprint) is different, current capacity is
lower, and the relay case dimensions are smaller than those of the conventional ISO relay.
The intermittent wipe relay is a electromechanical device that switches battery current to the
windshield wiper motor when the relay coil is grounded by the Central Timer Module (CTM) in
response to inputs from the windshield wiper (multi-function) switch. See Intermittent Wipe Relay in
the Diagnosis.
The intermittent wipe relay is located in a connector that is taped back to the instrument panel wire
harness above the inboard side of the glove box opening. The intermittent wipe relay cannot be
repaired and, if faulty or damaged, it must be replaced.

4WD Switch: Description and Operation
Vehicles equipped with four wheel drive (4WD) have an indicator switch mounted on the front axle
assembly. This switch is closed to ground when the transfer case is shifted to four wheel drive
mode and the engine is running on some vehicles. While in four wheel drive, the front and rear
axles will operate together. With this input, the CAB is able to modify its operation to allow for 4WD
operation. Should a need for antilock operation occur while in four wheel drive, the CAB will extend
the amount of allowable dump cycles.

Wheel Speed Sensor: Description and Operation Four Wheel Antilock Brakes
OPERATION
The ABS brake system uses 3 wheel speed sensors. A sensor is mounted to each front steering
knuckles. The third sensor is mounted on top of the rear axle differential housing. The sensor is a
magnet coil that is mounted over a tone wheel front/exciter ring rear with an air gap between them.
The sensors measure the wheel speed by monitoring the rotation of the tone wheels front/exciter
ring rear. As the teeth of the tone wheels front/exciter ring rear move through the magnetic field of
the sensor an AC voltage is generated. This signal frequency increases or decreases proportionally
to the speed of the wheel. The Controller Antilock Brake (CAB) monitors these signals for changes
in wheel deceleration. If the CAB detects a sudden wheel or wheels deceleration within a
predetermined amount the CAB will activate the ABS system.
CIRCUIT OPERATION
The all wheel Anti-Lock Brake System (ABS) uses three wheel speed sensors; a single sensor for
both rear wheels and individual sensors for the front wheels. The single sensor used for the rear
wheels mounts on the top of the rear axle differential housing. Each sensor converts wheel speed
into an electrical signal that is transmitted to the Controller Anti-Lock Brakes (CAB). A pair of
twisted wires connect to each sensor and provide signals to the CAB.
Circuits B6 and B7 provide signals to the CAB from the right front wheel speed sensor. Circuit B6,
which provides the LOW signal, connects to cavity 15 of the CAB. Circuit B7 connects to cavity 2 of
the CAB and provides the HIGH signal.
Circuits B8 and B9 provide signals to the CAB from the left front wheel speed sensor. Circuit B8,
which provides the LOW signal, connects to cavity 16 of the CAB. Circuit B9 connects to cavity 3
and provides the HIGH signal.
Circuit B114 connects to cavity 14 of the CAB and to circuit B2 of the rear wheel speed sensor
harness at the sensor connector. Circuit B113 connects to cavity 1 of the CAB and to circuit B1 at
the rear wheel speed sensor harness connector. Circuit B114 provides the rear wheel speed
sensor LOW input while circuit B113 provides the HIGH input.

Wheel Speed Sensor: Description and Operation Kelsey-Hayes Antilock Brake Systems
The EBC 325 ABS system uses one wheel speed sensor on each front wheel, and one speed
sensor mounted in the rear axle for the rear wheels.
The RWAL II uses only one speed sensor mounted in the rear axle for the rear wheels.
The sensor measures the wheel speed by monitoring a rotating tone wheel. The signal generated
by the sensor and tone wheel is transmitted to the CAB.
Each sensor has:
- a metal tone wheel with teeth on its outside diameter
- a magnetic/coil pick-up (speed sensor) that is mounted to a fixed component
- an air gap between the tone wheel and the speed sensor assembly
As the teeth of the tone wheel move through the magnetic field of the sensor, an AC voltage is
generated. This signal frequency increases or decreases proportionally to the speed of the wheel.
The CAB monitors this signal to check for a sudden change in single or multiple wheel
decelerations. If the deceleration of one or more wheels is not within a predetermined amount, the
antilock module takes control.
Diagnostically, the coil of wheel speed sensors have different amounts of resistance based upon
the sensor type. When measured across the connector two terminals, the resistance should be:
AN, DN, BE and BR:
4x4 front sensors 945-1155 ohms
AB, AN and DN:
4x2 front sensors 2500-2955 ohms
BE and BR:
4x2 front sensors 1000-1250 ohms
AB, AN, DN, BE and BR:
All rear sensors 1600-2300 ohms
NOTE: For all resistance ranges add 30% to the value for extreme heat, subtract 30% for extreme
cold.)
The rear wheel speed sensor used on all vehicles have the same resistance value, but there are
two different sensors. Therefore, it is important to replace the rear wheel speed sensor with the
proper part.
On a EBC 325 system each front wheel speed is monitored through the speed sensor mounted at
the wheel end of the hub. On a EBC 325 and RWAL II system the rear wheel speed is monitored
through the speed sensor mounted in the rear axle assembly.
The CAB will disable antilock control, illuminate the ABS warning light circuit via COD, and store
trouble codes if it detects a problem with any or all of the wheel speed sensors:
- incorrect circuit resistance when checked with no vehicle movement
- incorrect sensor output during vehicle movement
- erratic sensor output during vehicle movement

Cruise Control Switch: Description and Operation
SYSTEM OPERATION
Two separate speed control switch modules are mounted on the steering wheel to the left and right
side of the driver's airbag module. Within the two switch modules, five momentary contact
switches, supporting seven different speed control functions are used. The outputs from these
switches are filtered into one input. The Powertrain Control Module (PCM) determines which output
has been applied through resistive multiplexing. The input circuit voltage is measured by the PCM
to determine which switch function has been selected.
A speed control indicator lamp, located on the instrument panel cluster is energized by the PCM via
the CCD Bus. This occurs when speed control system power has been turned ON, and the engine
is running.
The two switch modules are labeled: ON/OFF, SET, RESUME/ACCEL, CANCEL and COAST.
Refer to the owner's manual for more information on speed control switch functions and setting
procedures. The individual switches cannot be repaired. If one individual switch fails, the switch
module must be replaced.

High Pressure Sensor / Switch: Description and Operation
SYSTEM OPERATION
High Pressure Cut-Off Switch The high pressure cut-off switch is located on the discharge line near
the condenser. The switch is screwed onto a fitting that contains a Schrader-type valve, which
allows the switch to be serviced without discharging the refrigerant system. The discharge line
fitting is equipped with an 0-ring to seal the switch connection.
The high pressure cut-off switch is connected in series electrically with the low pressure cut-off
switch between the fin sensing cycling clutch switch and the Powertrain Control Module (PCM).
The switch contacts open and close causing the PCM to turn the compressor clutch on and off.
This prevents compressor operation when the discharge line pressure approaches high levels.
The high pressure cut-off switch contacts are open when the discharge line pressure rises above
about 3100 to 3375 kPa (450 to 490 psi). The switch contacts will close when the discharge line
pressure drops to about 1860 to 2275 kPa (270 to 330 psi).
The high pressure cut-off switch is a factory-calibrated unit. The switch cannot be adjusted or
repaired and, if faulty or damaged, it must be replaced.

Low Pressure Sensor / Switch: Description and Operation
SYSTEM OPERATION
Fin Sensing Cycling Clutch Switch
Fin Sensing Cycling Clutch Switch The fin sensing cycling clutch switch is used on this model to
signal the Powertrain Control Module (PCM) to cycle the compressor clutch on arid off in order to
control the evaporator temperature. Controlling the evaporator temperature prevents condensate
water on the evaporator fins from freezing and obstructing air conditioning system air flow.
The fin sensing cycling clutch switch consists of a probe and a switch unit. The probe, which is a
Negative Temperature Coefficient (NTC) thermistor in a capillary tube, is inserted between the front
evaporator coil fins to monitor evaporator temperature. The switch unit contains internal control
logic that monitors the input from the probe in order to switch an internal transistor that controls the
output to the PCM. when the fin sensing cycling clutch switch sees a temperature input below
about 1.60 °C (350 °F), it signals the PCM to cycle the compressor off. When the temperature input
reaches above about 3.90 °C (390 °F), the switch signals the PCM to cycle the compressor back
on.
The fin sensing cycling clutch switch can be accessed for service by removing the screws and
carefully lifting the front of the top cover up from the heater-A/C housing. The fin sensing cycling
clutch switch is a sealed unit and cannot be adjusted or repaired. If faulty or damaged, the switch
must be replaced.

Low Pressure Sensor / Switch: Testing and Inspection Fin Sensing Cycling Clutch Switch
Before testing the fin sensing cycling clutch switch, verity that the refrigerant system has the correct
refrigerant charge. Also check that both the low and high pressure cut-off switches are functional,
and confirm that the compressor clutch is operational. Use a volt/ohmmeter to test the switch.
1. Turn the ignition switch in the On position. Place the heater-A/C mode control switch in any A/C
position. Check for battery voltage at the fused
ignition switch output (run/start) circuit cavity of the fill sensing cycling clutch switch wire harness
connector. If OK, go to Step 3. If not OK, repair the open circuit to the fuse in the junction block as
required.
2. With the ambient temperature between 20 to 30° C (68 to 900 F), start the engine and run the air
conditioning system. The compressor clutch
should cycle on and off two to three times per minute. If the clutch fails to cycle at this rate in these
temperatures, replace the faulty fin sensing cycling clutch switch.
NOTE: If the ambient temperature is above 32° C (90° F) the compressor clutch may stay engaged
and not cycle due to the high heat load. This condition is normal.

Low Pressure Sensor / Switch: Testing and Inspection Low Pressure Cut-Off Switch
Before performing diagnosis of the low pressure cut-off switch, remember that lower ambient
temperatures, below about -1° C (30° F), during cold weather will open the switch contacts and
prevent compressor operation due to the pressure/temperature relationship of the refrigerant.
Also verify that the refrigerant system has the correct refrigerant charge. See Refrigerant System
Charge in the Service Procedures.
1. Disconnect and isolate the battery negative cable. 2. Unplug the low pressure cut-off switch wire
harness connector from the switch on the suction line jumper fitting. 3. Install a jumper wire
between the two cavities of the low pressure cut-off switch wire harness connector. 4. Connect a
manifold gauge set to the refrigerant system service ports. See Refrigerant System Service
Equipment and Refrigerant System Service
Ports.
5. Connect the battery negative cable. 6. Place the heater-A/C mode control switch knob in any
A/C position and start the engine. 7. Check for continuity between the two terminals of the low

Fuel Gauge Sender: Description and Operation
DESCRIPTION
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a vanable resistor (track). The resistor track is used to
send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for
OBD II emission requirements.
OPERATION
For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the
sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and
arm move down. This increases the sending unit resistance causing the fuel gauge to read empty.
After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus
circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading.
For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the
sending unit to the PCM to indicate fuel level. The purpose of this feature is to prevent the OBD II
system from recording/setting false misfire and fuel system monitor trouble codes. The feature is
activated if the fuel level in the tank is less than approximately 15 percent of its rated capacity. If
equipped with a Leak Detection Pump (EVAP system monitor), this feature will also be activated if
the fuel level in the tank is more than approximately 85 percent of its rated capacity.

Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Instrument Panel > Fuel Gauge Sender >
Component Information > Technical Service Bulletins > Page 514
Fuel Gauge Sender: Testing and Inspection
The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down,
electrical resistance will change. To test the gauge sending unit only, it must be removed from
vehicle. The unit is part of the fuel pump module. Refer to Fuel Pump Module Removal Installation
for procedures.
Measure the resistance across the sending unit terminals. With float in up position, resistance should be 20 ohms ± 6 ohms.
- With float in down position, resistance should be 220 ± 6 ohms.

Brake Light Switch: Description and Operation Switch With RWAL System
The primary function of the switch,is to turn on the stop lamps during braking. The switch is also
used to send signals to components that must know when the brakes are applied, such as the
Powertrain Control Module (PCM), which uses the signal to cancel speed control. The Controller
Antilock Brake (CAB) uses the brake switch signal to monitor brake pedal application. When the
switch contacts open (brakes applied), the CAB receives the brake applied signal. The CAB then
monitors the ABS system to anticipate the need for an ABS stop.

Camshaft Position Sensor: Description and Operation
SYSTEM OPERATION
The camshaft position sensor is located in the distributor on all engines.
The sensor contains a hall effect device called a sync signal generator to generate a fuel sync
signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The
pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction
with the crankshaft position sensor to differentiate between fuel injection and spark events. It is
also used to synchronize the fuel injectors with their respective cylinders.
When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following
occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync
signal of approximately 5 volts.
When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following
occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts.

Camshaft Position Sensor: Testing and Inspection
Camshaft Position Sensor - Typical
The camshaft position sensor is located in the distributor on all engines.
To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain
Diagnostics Procedures service. To test the sensor only, refer to the following:
For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector
from the distributor. Using small paper clips, insert them into the backside of the distributor wire
harness connector to make contact with the terminals. Be sure that the connector is not damaged
when inserting the paper clips. Attach voltmeter leads to these paper clips.
1. Remove engine cover. 2. Connect the positive (+) voltmeter lead into the sensor output wire.
This is at done the distributor wire harness connector. For wire identification. 3. Connect the
negative (-) voltmeter lead into the ground wire. For wire identification. 4. Set the voltmeter to the
15 Volt DC scale. 5. Remove distributor cap from distributor (two screws). Rotate (crank) the
engine until the distributor rotor is pointed towards the rear of vehicle.
The movable pulse ring should now be within the sensor pickup.
6. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 7. If voltage is
not present, check the voltmeter leads for a good connection. 8. If voltage is still not present, check
for voltage at the supply wire. For wire identification. 9. If 5 volts is not present at supply wire,
check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for
this
test.
10. If voltage is still not present, perform vehicle test using the DRB scan tool. 11. If voltage is
present at cavity A-17, but not at the supply wire:
a. Check continuity between the supply wire. This is checked between the distributor connector and
cavity A-17 at the PCM. If continuity is not
present, repair the harness as necessary
b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the
PCM. If continuity is not present, repair the
harness as necessary
c. Check for continuity between the ground circuit wire at the distributor connector and ground. If
continuity is not present, repair the harness as
necessary.
12. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle
should fluctuate between 0 and 5 volts while the
engine is cranking. This verifies that the camshaft position sensor in the distributor is operating
properly and a sync pulse signal is being generated. If sync pulse signal is not present,
replacement of the camshaft position sensor is necessary.

Crankshaft Position Sensor: Description and Operation
SYSTEM OPERATION
Sensor Operation
Engine speed and crankshaft position are provided through the crankshaft position sensor. The
sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM
interprets the sensor input to determine the crankshaft position. The PCM then uses this position,
along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
On this engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its
outer edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM. For each engine revolution, there are 8 pulses generated on V-8 engines.
The engine will not operate if the PCM does not receive a crankshaft position sensor input.

Throttle Position Sensor: Testing and Inspection
The Throttle Position Sensor (TPS) can be tested with a digital voltmeter. The center terminal of
the TPS is the output terminal.
With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of
the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT).
- At idle, TPS output voltage should should be greater than 0.350 millivolts and less than 900
millivolts.
- At wide open throttle, TPS output voltage must be less than 4.5 volts.
- The output voltage should increase gradually as the throttle plate is slowly opened from idle to
WOT.
NOTE: For additional testing information and circuit diagnosis see Computers and Control
Systems/System Diagnosis/Procedures/Diagnostic Charts.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Information and Instructions > Page 666
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers.
- Connectors located on the instrument panel harness are C200 series numbers.
- Connectors located on the body harness are C300 series numbers.

Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and
Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram
Information and Instructions > Page 668
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Information and Instructions > Page 669
Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.
- ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE
CLOTHING.
Positive Temperature Coefficient
Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's
act like a solid state fuse. They are located in the

junction block, and are used to protect such items as: power door lock motors, power windows, and
various engine solenoids.
Positive Temperature Coefficient Symbol
A special symbol is used to identify these in the wiring diagrams.
Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

International symbols are used throughout the wiring diagrams. These symbols are consistent with
those being used around the world.
Take-Outs
The abbreviation T/O is used in the Component Location group to indicate a point at which the
wiring harness branches out to a component.
How to Find System & Component Diagrams
When trying to find the diagram for a specific component or system, use the Group Index
information or the Alphabetic Index to Wiring Diagrams under Electrical
Whenever a reference exists to another sheet or figure, find the corresponding diagram using the
Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number
for the subsequent diagram will match a listed group shown.

Vehicle Speed Sensor: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation
Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of
the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check
voltage. Refer to the
appropriate test procedure.

Information and Instructions > Page 681
Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Throttle Position Sensor: Testing and Inspection
The Throttle Position Sensor (TPS) can be tested with a digital voltmeter. The center terminal of
the TPS is the output terminal.
With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of
the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT).
- At idle, TPS output voltage should should be greater than 0.350 millivolts and less than 900
millivolts.
- At wide open throttle, TPS output voltage must be less than 4.5 volts.
- The output voltage should increase gradually as the throttle plate is slowly opened from idle to
WOT.
NOTE: For additional testing information and circuit diagnosis see Computers and Control
Systems/System Diagnosis/Procedures/Diagnostic Charts.

Camshaft Position Sensor: Description and Operation
SYSTEM OPERATION
The camshaft position sensor is located in the distributor on all engines.
The sensor contains a hall effect device called a sync signal generator to generate a fuel sync
signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The
pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction
with the crankshaft position sensor to differentiate between fuel injection and spark events. It is
also used to synchronize the fuel injectors with their respective cylinders.
When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following
occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync
signal of approximately 5 volts.
When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following
occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts.

Camshaft Position Sensor: Testing and Inspection
Camshaft Position Sensor - Typical
The camshaft position sensor is located in the distributor on all engines.
To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain
Diagnostics Procedures service. To test the sensor only, refer to the following:
For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector
from the distributor. Using small paper clips, insert them into the backside of the distributor wire
harness connector to make contact with the terminals. Be sure that the connector is not damaged
when inserting the paper clips. Attach voltmeter leads to these paper clips.
1. Remove engine cover. 2. Connect the positive (+) voltmeter lead into the sensor output wire.
This is at done the distributor wire harness connector. For wire identification. 3. Connect the
negative (-) voltmeter lead into the ground wire. For wire identification. 4. Set the voltmeter to the
15 Volt DC scale. 5. Remove distributor cap from distributor (two screws). Rotate (crank) the
engine until the distributor rotor is pointed towards the rear of vehicle.
The movable pulse ring should now be within the sensor pickup.
6. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 7. If voltage is
not present, check the voltmeter leads for a good connection. 8. If voltage is still not present, check
for voltage at the supply wire. For wire identification. 9. If 5 volts is not present at supply wire,
check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for
this
test.
10. If voltage is still not present, perform vehicle test using the DRB scan tool. 11. If voltage is
present at cavity A-17, but not at the supply wire:
a. Check continuity between the supply wire. This is checked between the distributor connector and
cavity A-17 at the PCM. If continuity is not
present, repair the harness as necessary
b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the
PCM. If continuity is not present, repair the
harness as necessary
c. Check for continuity between the ground circuit wire at the distributor connector and ground. If
continuity is not present, repair the harness as
necessary.
12. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle
should fluctuate between 0 and 5 volts while the
engine is cranking. This verifies that the camshaft position sensor in the distributor is operating
properly and a sync pulse signal is being generated. If sync pulse signal is not present,
replacement of the camshaft position sensor is necessary.

Crankshaft Position Sensor: Description and Operation
SYSTEM OPERATION
Sensor Operation
Engine speed and crankshaft position are provided through the crankshaft position sensor. The
sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM
interprets the sensor input to determine the crankshaft position. The PCM then uses this position,
along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
On this engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its
outer edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM. For each engine revolution, there are 8 pulses generated on V-8 engines.
The engine will not operate if the PCM does not receive a crankshaft position sensor input.

NOTE:
THIS INFORMATION APPLIES TO VEHICLES BUILT BEFORE JAN 16, 1998 MDH (0116XX)
EQUIPPED WITH GASOLINE ENGINES AND A 42/44/46 OR 47RE TRANSMISSION.
SYMPTOM/CONDITION:
Some vehicles may experience bucking during wide open throttle (WOT) acceleration. The bucking
occurs at approximately 5300 RPM. This condition may be caused by reaching the high RPM fuel
shut off rev limit before the transmission can shift into the next higher gear and is most likely to
occur with high electrical loads (high beams on, heated back lite, heated seats, radio, HVAC blower
on MAX etc.). During high current demands, the generator may emit electrical noise that can affect
the transmission governor pressure sensor output. If this occurs, the transmission may not shift
properly to the next higher gear under (WOT) acceleration conditions and therefore reach the fuel
shut off rev limiter. This may be seen most often between the 2-3 shift but can also be experienced
between the 1-2 shift.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual,
verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes
(DTC's) are present, record them on the repair order and repair as necessary before proceeding
further with this bulletin.
NOTE:
ONLY PERFORM THE FOLLOWING PROCEDURE SAFELY ON A HIGHWAY OR ROAD
OBEYING ALL POSTED SPEED LIMITS AND LAWS.
Attempt to duplicate the condition by switching on all accessory loads and driving the vehicle with
WOT accelerations through a shift sequence to see if the engine will reach the fuel shut off rev
limiter before the 2-3 or 1-2 shift is made.
If the bucking condition is experienced at approximately 5300 RPM before making the appropriate
upshifts, switch off all electrical loads and repeat the procedure. Repeat the procedure with the
electrical loads on and off a second time. If the bucking occurs with the electrical loads on and
does not occur with the loads off, perform the Repair Procedure.

DATE: September 22, 2000
SUBJECT: Steering Wander Diagnosis
OVERVIEW: This bulletin provides a diagnostic procedure for steering wander.
MODELS: 1998-2001 (AB) Ram Van/Wagon
SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight
steering corrections are necessary to be able to keep the vehicle moving in a straight line.
Steering wander can be created by a number of different conditions including but not limited to the
following:
^ Non-factory installed options.
^ Tires or wheels of different size.
^ Aftermarket wheels.
^ Tires that have a belt that has shifted.
^ Incorrect tire pressure.
^ A vehicle that is carrying extra added weight (e.g. tool boxes).
^ Steering and/or suspension components that are worn or damaged.
^ Wheel bearings that are loose, worn, or damaged.
^ A vehicle that is not within alignment specifications.
NOTE:
UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS,
CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER.
The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering
system components are functioning as designed and are not the root cause of steering wander.
DIAGNOSIS:
1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may
cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to
exceed the front or rear Gross Axle Weight Rating (GAWR).
2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged
and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to
wander and should be replaced before continuing with the diagnosis.
3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove
box).
NOTE:

Alignment: Description and Operation
GENERAL INFORMATION
Wheel Alignment Measurements
Wheel alignment involves the correct positioning of the wheels in relation to the vehicle. The
positioning is accomplished through suspension and steering linkage adjustments. An alignment is
considered essential for efficient steering, good directional stability and to minimize tire wear. The
most important measurements of an alignment are caster, camber and toe.
Caster - is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the
knuckle forward provides negative caster. Tilting the top of the knuckle rearward provides positive
caster. Positive caster promotes directional stability. This angle enables the front wheels to return
to a straight ahead position after turns.
Camber - is the inward or outward tilt of the wheel relative to the center of the vehicle. Tilting the
top of the wheel inward provides negative camber. Tilting the top of the wheel outward provides
positive camber. Incorrect camber will cause wear on the inside or outside edge of the tire.
Toe - is the difference between the leading inside edges and trailing inside edges of the front tires.
Uneven wheel toe position cause's unstable steering, uneven tire near and steering wheel
off-center. The wheel toe position is the final front wheel alignment adjustment.
Thrust Angle - is the angle of the rear axle relative to the centerline of the vehicle. Incorrect thrust
angle can cause off-center steering and excessive tire wear. This angle is not adjustable, damaged
component(s) must be replaced to correct the thrust angle.

Alignment: Testing and Inspection
PRE-ALIGNMENT INSPECTION
Before starting wheel alignment, the following inspection and necessary corrections must be
completed. 1. Inspect tires for size, air pressure and tread wear. 2. Inspect front wheel bearings for
wear or adjustment. 3. Inspect front wheels for excessive radial or lateral runout and balance. 4.
Inspect ball studs, linkage pivot points and steering gear for looseness, roughness or binding. 5.
Inspect suspension components for wear and noise.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Page 838
Alignment: Service and Repair
GENERAL INFORMATION
The front wheel alignment angles should be set to preferred specifications. This will prevent
abnormal tire tread wear.
Before each alignment reading the vehicle should be jounced (rear first, then front). Grasp each
bumper at the center and jounce the vehicle up and down several times. Always release the
bumper in the down position.
CAMBER AND CASTER
Camber and caster angle adjustments involve repositioning the upper suspension arm pivot bar.
Alignment adjustments are accomplished by changing the position of the pivot bar.
Adjuster Tool 8199, or equivalent is used to adjust the camber and caster angles.
Tools Attached To Frame
1. Clamp the tool on the upper suspension arm frame bracket. Use the two clamp bolts to attach
the tool to the bracket. 2. With the adjustment tools installed, loosen both upper suspension arm
bolts completely. 3. Tighten or loosen the tool adjustment bolts to move the upper suspension arm
inward or outward to obtain the proper camber and caster
angles.
Caster: Move the rear position of the pivot bar in or out. This will change the caster angle
significantly and camber angle only slightly. To retain the camber while adjusting caster, move the
rear pivot bar in or out. Move the forward pivot very slightly in the opposite direction.
NOTE: For example, to increase a positive caster angle move the rear position of the pivot bar
inward. Move the front of pivot bar outward until the original camber angle is obtained.
Camber: Move the forward position of the pivot bar in or out. This will change the camber angle
significantly and caster angle only slightly. The camber angle should be adjusted to the service
specifications. Tighten the pivot bar bolts to 298 Nm (220 ft. lbs.).

Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Page 839
TOE POSITION
The wheel toe position is the final adjustment procedure. 1. Secure the steering wheel with the
front wheels in the straight ahead position. For power steering vehicles, start the engine before
straightening
the wheels.
2. Loosen the tie rod adjustment sleeve clamp bolts.
3. Adjust the wheel toe position by rotating the tie rod adjustment sleeve. 4. Position the adjustment
sleeve clamps so the ends are not located at the sleeve slot. Tighten the tie rod sleeve clamps to:
- Standard Duty: 23 Nm (17 ft. lbs.)
- Heavy Duty: 35 Nm (26 ft. lbs.)
Ensure the clamp bolts are located at the underside of the sleeve.
5. Verify camber, caster and toe position.

- Insert other end of Adaptor Tool hose into a graduated container.
4. Remove the fuel fill cap. 5. To activate fuel pump and pressurize system, obtain DRB scan tool
and actuate ASD Fuel System Test. 6. A good fuel pump will deliver at least 1/4 liter of fuel in 7
seconds.
- Do not operate fuel pump for longer than 7 seconds with fuel line disconnected as fuel pump
module reservoir may run empty.
a. If capacity is lower than specification, but fuel pump can be heard operating through fuel fill cap
opening, check for a kinked/damaged fuel
supply line somewhere between fuel rail and fuel pump module.
b. If line is not kinked/damaged, and fuel pressure is OK, but capacity is low, replace fuel filter/ fuel
pressure regulator. The filter/regulator may be serviced separately on certain applications.
- Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information.

Fuel Pressure: Testing and Inspection Fuel Pressure Leak Down Test
Fig 9 Connecting Adaptor Tool -- Typical
Fig. 8 Installing Adapter Tool And Pressure Gauge
NOTE: Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity
Test.
Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational.
After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid
gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure
that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the
electric fuel pump is activated, fuel pressure should immediately rise to specification.
Abnormally long periods of cranking to restart a hot engine that has been shut down for a short
period of time may be caused by: Fuel pressure bleeding past a fuel injector(s).
- Fuel pressure bleeding past the check valve in the fuel pump module.
1. Disconnect the fuel inlet line at fuel rail.
- On some engines, air cleaner housing removal may be necessary before fuel line disconnection.
2. Connect the appropriate Fuel Line Pressure Test Adapter Tool (number 6539, 6631, 6541 or
6923) between the disconnected fuel line and fuel rail
(Fig. 9) or (Fig. 10).
3. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test
port on the appropriate Adaptor Tool.
- The fittings on both tools must be in good condition and free from any small leaks before
performing the proceeding test.
4. Start engine and bring to normal operating temperature.

Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Fuel Pressure > System
Information > System Diagnosis > Fuel Pressure Leak Down Test > Page 851
5. Observe test gauge. Normal operating pressure should be 339 kPa +/- 34 kPa (49.2 psi +/- 5
psi). 6. Shut engine off. 7. Pressure should not fall below 30 psi for five minutes. 8. If pressure falls
below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module,
or a fuel tube/line is leaking. 9. Again, start engine and bring to normal operating temperature.
10. Shut engine off. 11. Testing for fuel injector or fuel rail leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on
Adapter Tool.
- If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking.
12. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T"
on Adapter Tool.
- If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line.
- If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump
or filter/ regulator may be leaking.
NOTE: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A
slow loss of pressure usually indicates a defective check valve in the electric fuel pump.
The electric fuel pump is not serviced separately -- Replace the fuel pump module assembly. The
filter/ regulator may be replaced separately on certain applications. Refer to Fuel Filter/Fuel
Pressure Regulator Removal/installation for additional information.

Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow hack into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational. After the vehicle has cooled down fuel pressure may drop to 0 psi (cold fluid
contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel
injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal
condition. When the electric fuel pump is activated, fuel pressure should immediately rise to
specification.
All fuel systems are equipped with a fuel tank module mounted, combination fuel filter/fuel pressure
regulator. The fuel pressure regulator is not controlled by engine vacuum.
WARNING: The fuel system is under constant fuel pressure even with the engine off. Before
disconnecting fuel line at fuel rail, this pressure must be released. Refer to the fuel system
pressure release procedure.
NOTE: To perform this test you will need to remove the engine cover.
1. Remove the protective cap at the fuel rail test port. Connect the 0-414 kPa (0-60 psi) fuel
pressure gauge (from gauge set 5069) to the test port
pressure fitting on the fuel rail.
2. Start and warm the engine and note pressure gauge reading. Fuel pressure should be 3.39 kPa
+/- 34 kPa (49.2 psi +/- 5 psi) at idle. 3. If engine runs but pressure is below 44.2 psi, check for a
kinked fuel supply line somewhere between fuel rail and fuel pump module. If line is not
kinked, replace fuel pump module assembly. Refer to Fuel Pump Removal/Installation.
4. If operating pressure is above 54.2 psi, electric fuel pump is OK, but fuel pressure regulator is
defective. Replace fuel filter/fuel pressure regulator.
Certain filter/regulators may be serviced separately and some require the replacement of the fuel
pump module assembly Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for more
information.

Ignition Cable: Description and Operation
SYSTEM OPERATION
Spark plug cables are sometimes referred to as secondary ignition wires. These cables transfer
electrical current from the ignition coil(8) and/or distributor, to individual spark plugs at each
cylinder. The resistive spark plug cables are of nonmetallic construction. The cables provide
suppression of radio frequency emissions from the ignition system.

Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Ignition Cable > Component
Information > Technical Service Bulletins > Page 915
Ignition Cable: Testing and Inspection
Heat Shields
Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and
spark plugs. Terminals should be fully seated. The insulators should be in good condition and
should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are
cracked or torn must be replaced.
Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the
cables dry. Check for brittle or cracked insulation.
Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable
boot and spark plug . These shields protect the spark plug boots from damage (due to intense
engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug
cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat
shield.
Testing
When testing secondary cables for damage with an oscilloscope, follow the instructions of the
equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as
follows:
CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during
testing. This may cause possible heat damage to the catalytic converter. Total test time must not
exceed ten minutes.
With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to
a good engine ground. If the cable and spark plug are in good condition, the engine rpm should
drop and the engine will run poorly If engine rpm does not drop, the cable and/or spark plug may
not be operating properly and should be replaced. Also check engine cylinder compression.
With the engine not running, connect one end of a test probe to a good ground. Start the engine
and run the other end of the test probe along the entire length of all spark plug cables. If cables are
cracked or punctured, there will be a noticeable spark jump from the damaged area to the test
probe. The cable running from the ignition coil to the distributor cap can be checked in the same
manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This
can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket.
Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped,
remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from
spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode
in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable
from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not
within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable.
Test all spark plug cables in this manner.
Spark Plug Cable Resistance MINIMUM = MAXIMUM 250 Ohms Per Inch = 1000 Ohms Per Inch
3000 Ohms Per Foot = 12,000 Ohms Per Foot
To test ignition coil-to-distributor cap cab]e, do not remove the cable from the cap. Connect
ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of
cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart,
remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable.
If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace
the cable. Inspect the ignition coil tower for cracks, burns or corrosion.

REMOVAL AND INSTALLATION
Cable Removal
CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap,
twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off
with a steady, even force.
Engine Firing Order
Install cables into the proper engine cylinder firing order.
When replacing the spark plug and coil cables, route the cables correctly and secure in the proper
retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It
could also cause cross ignition of the plugs or short circuit the cables to ground.
When installing new cables, make sure a positive connection is made. A snap should be felt when
a good connection is made between the plug cable and the distributor cap tower.

Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for
cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the
inside (caused by condensation entering the cap through cracks). Replace any cap that displays
charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will
indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence
of mechanical interference with the rotor tip.

Spark Plug: Description and Operation
SYSTEM OPERATION
All engines use resistor type spark plugs. Remove the spark plugs and examine them for burned
electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in
which they were removed from the engine. A single plug displaying an abnormal condition indicates
that a problem exists in the corresponding cylinder.
Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or
oil fouled.

Spark Plug: Testing and Inspection
Normal Operating
Spark Plug Cable Resistance
The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is
evident with most grades of commercial gasoline. There will not be evidence of electrode burning.
Gap growth will not average more than approximately 0.025 mm (0.001 in) per 1600 km (1000
miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the
electrodes filed, have the gap set and then be installed.
Some fuel refiners in several areas of the United States have introduced a manganese additive
(MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug
to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by
coolant in the combustion chamber. Spark plug performance is not affected by MMT deposits.
Cold Fouling/Carbon Fouling
Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are
basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking
valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be
caused by a clogged air cleaner element or repeated short operating times (short trips).
Wet Fouling Or Gas Fouling
A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings,
leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently
overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This
condition can usually be resolved by cleaning and reinstalling the fouled plugs.
Oil Or Ash Encrusted
Oil Or Ash Encrusted
If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of
oil entry into that particular combustion chamber.
Electrode Gap Bridging
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component
Information > Specifications > Page 930
Electrode Gap Bridging
Electrode gap bridging may be traced to loose deposits in the combustion chamber. These
deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is
suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between
electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be
cleaned using standard procedures.
Scavenger Deposits
Scavenger Deposit
Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is
a normal condition caused by chemical additives in certain fuels. These additives are designed to
change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that
accumulation on the ground electrode and shell area may be heavy, but the deposits are easily
removed. Spark plugs with scavenger deposits can be considered normal in condition and can be
cleaned using standard procedures.
Chipped Electrode Insulator
Chipped Electrode Insulator
A chipped electrode insulator usually results from bending the center electrode while adjusting the
spark plug electrode gap. Under certain conditions, severe detonation can also separate the
insulator from the center electrode. Spark plugs with this condition must be replaced.
Preignition Damage
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component
Information > Specifications > Page 931
Preignition Damage
Preignition damage is usually caused by excessive combustion chamber temperature. The center
electrode dissolves first and the ground electrode dissolves somewhat latter. Insulators appear
relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine.
Determine if ignition timing is over advanced or if other operating conditions are causing engine
overheating. (The heat range rating refers to the operating temperature of a particular type spark
plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon
the thickness and length of the center electrodes porcelain insulator.)
Spark Plug Overheating
Spark Plug Overheating
Overheating is indicated by a white or gray center electrode insulator that also appears blistered.
The increase in electrode gap will be considerably in excess of 0.001 inch per 1000 miles of
operation. This suggests that a plug with a cooler heat range rating should be used. Over
advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug
overheating.

Spark Plug: Service and Repair
Heat Shields
Spark plug cable heat shields are pressed into the cylinder head to surround each cable boot and
spark plug.
If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides
of shield for removal. Each shield is slotted to allow for compression and removal. To install the
shields, align shield to machined opening in cylinder head and tap into place with a block of wood.
PLUG REMOVAL 1. Remove engine cover. 2. Always remove spark plug or ignition coil cables by
grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady
motion. Never pull directly on the cable. Internal damage to cable will result,
3. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area
around the spark plug. This will help prevent
foreign material from entering the combustion chamber.
4. Remove the spark plug using a quality socket with a rubber or foam insert. 5. Inspect the spark
plug condition.
Plug Cleaning The plugs may be cleaned using commercially available spark plug cleaning
equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before
adjusting gap.
CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will
remain on the spark plug insulator arid will cause plug misfire.
Plug Gap Adjustment Check the spark plug gap with a gap gauge tool. If the gap is not correct,
adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center
electrode.
Spark Plug Gap V-8 Engines: 1.01 mm (.040 in).
PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder
head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be
damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in
a change in the spark plug gap or a cracked porcelain insulator.
when replacing the spark plug and ignition coil cables, route the cables correctly and secure them
in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce
ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground.
1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark
plugs to 35-41 N.m (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs.

VISUAL DIAGNOSIS
Belt Ware Patterns
When diagnosing serpentine accessory drive belts, small cracks that run across the ribbed surface
of the belt from rib to rib, are considered normal. These are not a reason to replace the belt.
However, cracks running along a rib (not across) are not normal. Any belt with cracks running
along a rib must be replaced. Also replace the belt if it has excessive wear, frayed cords or severe
glazing. Refer to the Accessory Drive Belt Diagnosis charts for further belt diagnosis.
NOISE DIAGNOSIS
Noises generated by the accessory drive belt are most noticeable at idle. Before replacing a belt to
resolve a noise condition, inspect all of the accessory drive pulleys for alignment, glazing, or
excessive end play.

Refrigerant Filter: Description and Operation
SYSTEM OPERATION
A single filter-drier unit is used for both the front-only A/C system, and for the combined front and
rear A/C system. The filter-drier is mounted on the right side of the engine compartment in front of
the heater-A/C housing. It is located in the liquid line between the condenser outlet and the
evaporator inlet. Refrigerant enters the filter-drier as a high-pressure, high-temperature liquid.
The filter-drier performs a filtering action to prevent foreign material in the refrigerant from
contaminating the expansion valve. A desiccant bag is mounted inside the filter-drier canister to
absorb any moisture which may have entered and become trapped within the refrigerant system. In
addition, during periods of high demand air conditioner operation, the filter-drier acts as a reservoir
to store surplus liquid refrigerant.
The filter-drier cannot be repaired. If the filter-drier is faulty or damaged, if the refrigerant system
has been contaminated, or if the system has been left open to the atmosphere for an
indeterminable period, it must be replaced.

Coolant Line/Hose: Description and Operation
Radiator Hoses-Typical
Rubber hoses route coolant to and from the radiator, intake manifold and heater core. Radiator
lower hoses are spring-reinforced to prevent collapse from water pump suction at moderate and
high engine speeds. Inspect the hoses at regular intervals. Replace hoses that are cracked, feel
brittle when squeezed or swell excessively when the system is pressurized. The use of molded
replacement hoses is recommended. When performing a hose inspection, inspect the radiator
lower hose for proper position and condition of the spring.
Hose Clamp Tool-Typical
WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM
HOSES. WHEN REMOVING OR INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING
THIS TYPE OF CLAMP, SUCH AS SPECIAL CLAMP TOOL (NUMBER 6094). SNAP-ON CLAMP
TOOL (NUMBER HPC-20) MAY BE USED FOR LARGER CLAMPS. ALWAYS WEAR SAFETY
GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS.

Clamp Number/Letter Location
CAUTION: A number or letter is stamped into the tongue of constant tension clamps. If
replacement is necessary, use only an original equipment clamp with matching number or letter.
For all vehicles: In areas where specific routing and clamps are not provided, be sure that hoses
are positioned with sufficient clearance. Check clearance from exhaust manifolds and pipe, fan
blades, drive belts and sway bars. Improperly positioned hoses can be damaged, resulting in
coolant loss and engine overheating. Ordinary worm gear type hose clamps (when equipped) can
be removed with a straight screwdriver or a hex socket. To prevent damage to hoses or clamps,
the hose clamps should be tightened to 4 Nm (34 inch lbs.) torque. Do not over tighten hose
clamps.

Hose/Line HVAC: Description and Operation
SYSTEM OPERATION
Refrigerant Line The refrigerant lines and hoses are used to carry the refrigerant between the
various air conditioning system components. A barrier hose design with a nylon tube inner hose
liner is used for the R-134a air conditioning system on this vehicle. This nylon liner helps to further
contain the R-134a refrigerant, which has a smaller molecular structure than R-12 refrigerant. The
ends of the refrigerant hoses are made from lightweight aluminum, and use brazeless fittings.
Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air
conditioning system. Kinks and sharp bends reduce the flow of refrigerant in the system. A good
rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the
diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at
least 80 millimeters (3 inches) from the exhaust manifold.
High pressures are produced in the refrigerant system when the air conditioning compressor is
operating. Extreme care must be exercised to make sure that each of the refrigerant system
connections is pressure-tight and leak free. It is a good practice to inspect all flexible hose
refrigerant lines at least once a year to make sure they are in good condition and properly routed.
The refrigerant lines and hoses cannot be repaired and, if faulty or damaged, they must be
replaced.

Brake Fluid: Testing and Inspection
CAUTION:
The hydraulic fluid used in automotive brake systems is hygroscopic. This means that the hydraulic
fluid tends to absorb moisture from the atmosphere over periods of time. As hydraulic brake fluid
absorbs moisture, it effects the function of the vehicles hydraulic brake system. For this reason, the
vehicle's hydraulic brake fluid should be drained and replaced using fresh clean hydraulic brake
fluid every two years. When replacing hydraulic brake fluid, use only Mopar brake fluid or an
equivalent from a sealed container. Brake fluid must conform to DOT 3 specifications.
BRAKE FLUID CONTAMINATION
Indications of fluid contamination are swollen or deteriorated rubber parts. Swelling indicates the
presence of petroleum in the brake fluid.
To test for contamination, put a small amount of drained brake fluid in clear glass jar. If the fluid
separates into layers, there is mineral oil or other fluid contamination of the brake fluid.
If the brake fluid is contaminated, drain and thoroughly flush the brake system. Replace all the
rubber parts or components containing rubber coming into contact with the brake fluid. This
includes the master cylinder, proportioning valves, caliper seals, wheel cylinder seals, ABS
hydraulic control unit (HCU), and all hydraulic fluid hoses.

Brake Fluid: Service and Repair
Always clean the master cylinder filler caps before checking fluid level. If not cleaned, dirt from the
caps could enter the fluid.
Correct fluid level is to the bottom of the ring indicators on the reservoir. If necessary, add fluid to
correct the level. With disc brake equipped vehicles, fluid level in the front brake reservoir will
decrease slightly in proportion to normal lining wear.

Coolant: Fluid Type Specifications
The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle
operating conditions. The recommended mixture of 50/50 ethylene-glycol and water will provide
protection against freezing to -37° C (-35° F). The antifreeze concentration must always be a
minimum of 44%, year round, in all climates. If percentage is lower than 44%, engine parts may be
eroded by cavitation, and cooling system components may be severely damaged by corrosion.
Maximum protection against freezing is provided with a 68% antifreeze concentration, which
prevents freezing down to -67.7° C (-90° F). A higher percentage will freeze at a warmer
temperature. Also, a higher percentage of antifreeze can cause the engine to overheat because the
specific heat of antifreeze is lower than that of water.
100 Percent Ethylene-Glycol Should Not Be Used
Use of 100 Percent Ethylene-Glycol will cause formation of additive deposits in the system, as the
corrosive inhibitive additives in ethylene-glycol require the presence of water to dissolve. The
deposits act as insulation, causing temperatures to rise as high as 149° C (300° F). this
temperature is hot enough to melt plastic and soften solder. The increased temperature can result
in engine detonation. In addition, 100 % ethylene-glycol freezes at 22° C (-8° F).
Propylene-Glycol Formulations Should Not Be Used
Propylene-glycol formulations do not meet the required specifications. It's overall effective
temperature range is smaller than that of ethylene-glycol. The freeze point of 50/50
propylene-glycol and water is -32° C (-26° F), 5 degrees higher than ethylene-glycol's freeze point.
The boiling point (protection against summer boil-over) of propylene-glycol is 125° C (257° F) at
96.5 kPa (14 PSI), compared to 128° C (263° F) for ethylene-glycol. Use of propylene-glycol can
result in boil-over and freeze up. Propylene-Glycol also has a poorer heat transfer characteristics
than ethylene-glycol. This can increase cylinder head temperatures under certain conditions.
Propylene-Glycol/Ethylene-Glycol Mixtures Should Not Be Used
Propylene-glycol/ethylene-glycol mixtures can cause the destabilization of various corrosion
inhibitors, causing damage to the coling system components. Also, once ethylene-glycol and
propylene-glycol based coolants are mixed in the vehicle, conventional methods of determining the
freeze point will not be accurate. Both the refractive index and specific gravity differ between the
ethylene-glycol and propylene-glycol.
CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can
cause problems associated with 100 percent ethylene-glycol.

ETHYLENE-GLYCOL MIXTURES
The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle
open ating conditions. The recommended mixture of 50/50 ethylene-glycol and water will provide
protection against freezing to -37 deg. C 05 deg. F). The anti-freeze concentration must always be
a minimum of 44 percent, year-round in all climates. If percentage is lower than 44 percent, engine
parts may be eroded by cavitation, and cooling system components may be severely damaged by
corrosion. Maximum protection against freezing is provided with a 68 percent antifreeze
concentration, which prevents freezing down to -67.7 deg. C (-90 deg. F). A higher percentage will
freeze at a warmer temperature. Also, a higher percentage of antifreeze can cause the engine to
overheat because the specific heat of antifreeze is lower than that of water.
100 Percent Ethylene-Glycol Should Not Be Used in Chrysler Vehicles Use of 100 percent
ethylene-glycol will cause formation of additive deposits in the system, as the corrosion inhibitive
additives in ethylene-glycol require the presence of water to dissolve. The deposits act as
insulation, causing temperatures to rise to as high as 149 deg. C (300) deg. F). This temperature is
hot, enough to melt plastic and soften solder. The increased temperature can result in engine
detonation. In addition, 100 percent ethylene-glycol freezes at 22 deg. C (-8 deg. F).
Propylene-glycol Formulations Should Not Be Used in Chrysler Vehicles Propylene-glycol
formulations do not meet Chrysler coolant specifications. It's overall effective temperature range is
smaller than that of ethylene-glycol. The freeze point of 50/50 propylene-glycol and water is -32
deg. C (-26 deg. F). 5 deg. C higher than ethylene-glycol's freeze point. The boiling point
(protection against summer boil-over) of propylene-glycol is 125 deg. C (257 deg. F ) at 96.5 kPa
(14 psi), compared to 128 deg. C (263 deg. F) for ethylene-glycol. Use of propylene-glycol can
result in boil-over or freeze-up in Chrysler vehicles, which are designed for ethylene-glycol.
Propylene glycol also has poorer heat transfer characteristics than ethylene glycol. This can
increase cylinder head temperatures under certain conditions.
Propylene-glycol/Ethylene-glycol Mixtures Should Not Be Used in Chrysler Vehicles
Propylene-glycol/ethylene-glycol Mixtures can cause the destabilization of various corrosion
inhibitors, causing damage to the various cooling system components. Also, once ethylene-glycol
and propylene-glycol based coolants are mixed in the vehicle, conventional methods of determining
freeze point will not be accurate. Both the refractive index and specific gravity differ between
ethylene glycol and propylene glycol.
CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can
cause problems associated with 100 percent ethylene-glycol.

Coolant: Description and Operation Selection and Additives
The presence of aluminum components in the cooling system requires strict corrosion protection.
Maintain coolant at specified level with a mixture of ethylene-glycol based antifreeze and water.
Chrysler Corporation recommends Mopar Antifreeze or equivalent. If coolant becomes
contaminated or looses color, drain and flush cooling system and fill with correctly mixed solution.
A 0.25 percent emulsifiable oil is added to the radiator at the factory to prevent solder corrosion.
CAUTION: Do not use coolant additives that are claimed to improve engine cooling.

DATE: Sep. 5, 2000 SUBJECT: RTV Use On Corporate Axle
MODELS:
NOTE:
THIS BULLETIN APPLIES TO ALL VEHICLES EQUIPPED WITH AN 8.25, 9.25, OR C205F
CORPORATE AXLE.
DISCUSSION: The axle lubricant used in all corporate axles was changed in formulation starting at
the beginning of the 1998 model year. The corporate axles involved include: the 8.25 and 9.25 rear
axles, and the C205F front axle. The new lubricant in use is SAE 75W-90 p/n 05010320AA. The
lubricant change was made as a fuel economy improvement.
The new axle lubricant is more chemically aggressive/reactive when in contact with the previous
used Room Temperature Vulcanizable (RTV) sealant. Because of this condition, the RTV used in
assembly of the pan/cover to the axle housing was revised and improved.
When re-sealing axle covers, using the proper sealing material to minimize any potential sealant
breakdown is important. The only recommended sealing material for all corporate axle covers is
MOPAR RTV Sealant, p/n 05013477M. This RTV is red/orange in color.
NOTE:
IF SAE 75W-90 LUBRICANT IS USED TO REFILL ANY CORPORATE AXLE, THEN THE
RED/ORANGE MOPAR RTV SEALANT, P/N 05013477AA, SHOULD BE USED TO SEAL THE
COVER TO THE AXLE HOUSING.
To optimize sealant performance and enhance adhesion, flanges should be clean and free of
residual lubricant. The mating flanges should first be cleaned of any excess old RTV using a plastic
putty knife. Final cleaning/degreasing shall be done by spraying MOPAR Brake Parts Cleaner, p/n
04549623, on the carrier and cover flanges, followed by a wipe with a clean dry cloth. Care should
be taken to avoid spraying the parts cleaner inside the carrier. Once the RTV has been applied, the
axle cover is to be installed to the housing within 3 to 5 minutes to prevent skinning over of the
RTV.
NOTE:
IF THE AXLE COVER IS NOT INSTALLED WITHIN THE 3 TO 5 MINUTE TIME FRAME, THE
CARRIER COVER FACE MUST BE RECLEANED AND NEW RTV APPLIED, OR ADHESION
QUALITY WILL BE COMPROMISED.
Immediately install the cover attaching bolts and tighten them to the specified torque to prevent a
shimming effect by the RTV.

MODELS: 1998 (AB) Ram Van 1998 (AN) Dakota 1998 (BR/BE) Ram Truck 1998 (DN) Durango
1998 (XJ) Cherokee
DISCUSSION:
With the introduction of the 1998 model year, the axle lubricant in the 8-1/4 and 9-1/4 axles was
changed in formulation to improve fuel economy. When adding lubricant or if service is performed
that requires new lubricant use 75W90 p/n 5010320AA.
This lubricant is more aggressive toward RTV sealants than previously used axle lubricants. When
resealing the axle cover, using the proper sealing material to minimize any potential fluid foaming
and/or seal breakdown is important. Currently the only recommended sealing material for mall axle
covers or transmission pans is MOPAR RTV Sealant (grey in color) p/n 82300234.

DISCUSSION:
The factory fill power steering fluid for most 2004 model year Chrysler Group vehicles is ATF+4
(MS9602) and it provides superior performance at both low and high temperatures. WJ/WG and ZH
vehicles use unique power steering fluids. Refer to the table to identify factory fill and the approved
service power steering fluid by year and model. Note that MS9602 is Red in color and MS5931 and
MS9933 are Amber/Yellow in color. All three fluids will darken in color with usage and fluid color is
no longer an indication of fluid condition.
The part numbers for MS9602 are 05013457AA (quart) and 05013458AA (gallon). The part number
for MS5931 is 04883077 (quart). The part number for MB345 is 05127381AA.
MS9602 should not be mixed or used as a "topping off" fluid on systems requiring MS5931. On
some past models, MS9602 should be used as the replacement fluid. On these models, if a power
steering system is being serviced that results in a large fluid loss, such as a pump, hose or
gear/rack replacement, the complete system should be drained and filled with MS9602.

Refrigerant: Description and Operation
SYSTEM OPERATION
The refrigerant used in this air conditioning system is a HydroFluoroCarbon (HFC), type R-134a.
Unlike R-12, which is a ChloroFluoroCarbon (CFC), R-134a refrigerant does not contain
ozone-depleting chlorine. R-134a refrigerant is a non-toxic, non-flammable, clear, and colorless
liquefied gas.
Even though R-134a does not contain chlorine, it must be reclaimed and recycled just like
CFC-type refrigerants. This is because R-134a is a greenhouse gas and can contribute to global
warming.
R-134a refrigerant is not compatible with R-12 refrigerant in an air conditioning system. Even a
small amount of R-12 added to an R-134a refrigerant system will cause compressor failure,
refrigerant oil sludge or poor air conditioning system performance. In addition, the PolyAlkylene
Glycol (PAG) synthetic refrigerant oils used in an R-134a refrigerant system are not compatible
with the mineral-based refrigerant oils used in an R-12 refrigerant system.
R-134a refrigerant system service ports, service tool couplers and refrigerant dispensing bottles
have all been designed with unique fittings to ensure that an R-134a system is not accidentally
contaminated with the wrong refrigerant (R-12). There are also labels posted in the engine
compartment of the vehicle and on the compressor identifying to service technicians that the air
conditioning system is equipped with R-134a.

Refrigerant Oil: Service and Repair
Refrigerant Oil Level
Refrigerant Oil Capacities
When an air conditioning system is assembled at the factory, all components except the
compressor and the combination coil, if the vehicle is so equipped, are refrigerant oil free. After the
refrigerant system has been charged and operated, the refrigerant oil in the compressor and the
combination coil is dispersed throughout the refrigerant system. The combination coil, evaporator,
filter-drier, condenser, and compressor will each retain a significant amount of the needed
refrigerant oil.
It is important to have the correct amount of oil in the refrigerant system. This ensures proper
lubrication of the compressor. Too little oil will result in damage to the compressor. Too much oil
will reduce the cooling capacity of the air conditioning system.
It will not be necessary to check the oil level in the compressor or to add oil, unless there has been
an oil loss. An oil loss may occur due to a rupture or leak from a refrigerant line, a connector fitting,
a component, or a component seal. If a leak occurs, add 30 milliliters (1 fluid ounce) of refrigerant
oil to the refrigerant system after the repair has been made. Refrigerant oil loss will be evident at
the leak point by the presence of a wet, shiny surface around the leak.
Refrigerant oil must be added when a filter-drier, evaporator coil, combination coil, or condenser
are replaced. See the Refrigerant Oil Capacities chart. When a compressor is replaced, the
refrigerant oil must be drained from the old compressor and measured. Drain all of the refrigerant
oil from the new compressor, then fill the new compressor with the same amount of refrigerant oil
that was drained out of the old compressor.

System Bleeding Procedures
Brake Bleeding: Service and Repair Antilock Brake System Bleeding Procedures
W/ Four Wheel Antilock Brakes
ABS system bleeding requires conventional bleeding methods plus use of the DRB scan tool. The
procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and
bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to
remove any air remaining in the system.
1. Perform base brake bleeding. 2. Connect scan tool to the Data Link Connector. 3. Select
ANTILOCK BRAKES, followed by MISCELLANEOUS, then BLEED BRAKES. Follow the
instructions displayed. When scan tool
displays TEST COMPLETE, disconnect scan tool and proceed.
4. Perform base brake bleeding a second time. 5. Top off master cylinder fluid level and verify
proper brake operation before moving vehicle.
W/ Rear Wheel Antilock Brakes
GENERAL INFORMATION
RWAL brake bleeding can be performed manually, or with pressure bleeding equipment.
Use Mopar DOT 3 brake fluid, or an equivalent meeting SAE J1703-F and DOT 3 standards, to fill
and bleed the brake system.
Bleed only one brake component at a time. Recommended bleed sequence is: master cylinder
- combination valve
- rear antilock valve
- left rear wheel
- right rear wheel
- right front wheel
- left front wheel
MANUAL BLEEDING
Use a bleed hose at each caliper/cylinder bleed screw. Attach one end of the hose to the bleed
screw and insert the opposite end in glass container partially filled with brake fluid. A glass
container makes it easier to see air bubbles as they exit the bleed hose. Be sure the end of the
bleed hose remains immersed in fluid. This prevents air from being drawn back into the system.
Do not allow the master cylinder to run out of fluid when bleeding the brakes. An empty cylinder will
allow air to be drawn back into the system. Check fluid level frequently during bleeding operations.
Be sure to tighten each brake line fitting, or bleed screw once bleeding is completed. Loose fittings
and bleed screws allows air to enter the system.
PRESSURE BLEEDING
If pressure bleeding equipment will be used, the front brake metering valve will have to be held
open to bleed the front brakes. The valve stem is located in the forward end of the combination
valve. The stem must either be pressed inward, or held outward slightly. a spring clip tool or helper
is needed to hold the valve stem in position.
Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the
tank manufacturers pressure recommendations. Generally, a tank pressure of 15 - 20 psi is
sufficient for bleeding.
Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to
leakage, or drawing air back into the system.

Brake Bleeding: Service and Repair Base Brake System Bleeding
GENERAL INFORMATION
Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards
only. Use fresh, clean fluid from a sealed container at all times.
Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into
small bubbles that are distributed throughout the hydraulic system. This will make additional
bleeding operations necessary.
Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will
allow additional air to be drawn into the system. Check the cylinder fluid level frequently and add
fluid as needed.
Bleed only one brake component at a time in the following sequence: master cylinder
- combination valve
- right rear wheel
- left rear wheel
- right front wheel
- left front wheel
MANUAL BLEEDING
1. Remove reservoir filler caps and fill reservoir with Mopar, or equivalent quality DOT 3 brake fluid.
2. If calipers, or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws.
Then close each bleed screw as fluid starts to
drip from it. Top off master cylinder reservoir once more before proceeding.
Bleed Hose Setup
3. Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially
filled with brake fluid. Be sure end of bleed hose is
immersed in fluid.
4. Open up bleeder, then have a helper press down the brake pedal. Once the pedal is down close
the bleeder. Repeat bleeding until fluid stream is
clear and free of bubbles. Then move to the next wheel.
PRESSURE BLEEDING
Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the
tank manufacturers pressure recommendations. Generally, a tank pressure of 15 - 20 psi is
sufficient for bleeding.
Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to
leakage, or drawing air back into the system. Use adapter provided with the equipment or Adapter
6921 or equivalent.

Malfunction Indicator Lamp: Description and Operation
Data Link Connector
As a functional test, the MIL (check engine) illuminates at key-on before engine cranking.
Whenever the Powertrain Control Module (PCM) sets a Diagnostic Trouble Code (DTC) that affects
vehicle emissions, it illuminates the MIL. If a problem is detected, the PCM sends a message to the
instrument cluster to illuminate the lamp. The PCM illuminates the MIL only for DTC's that affect
vehicle emissions. There are some monitors that may take two consecutive trips, with a detected
fault, before the MIL is illuminated. The MIL stays on continuously when the PCM has entered a
Limp-In mode or identified a failed emission component. Also, the MIL either flashes or illuminates
continuously when the PCM detects active engine misfire.
Additionally, the PCM may reset (turn off) the MIL when one of the following occur:
^ PCM does not detect the malfunction for 3 consecutive trips (except misfire and Fuel system
Monitors).
^ PCM does not detect a malfunction while performing three successive engine misfire or fuel
system tests. The PCM performs these tests while the engine is operating within ± 375 RPM of and
within 10 % of the load of the operating condition at which the malfunction was first detected.

The rim size is on the safety certification label located on the drivers door shut face. The size of the
rim is determined by the drivetrain package. Original equipment wheels are designed for operation
up to the specified maximum vehicle capacity.
Fig. 1
All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised
sections between the rim flanges and rim drop well called safety humps.
Initial inflation of the tire forces the bead over these raised sections. In case of rapid loss of air
pressure, the raised sections help hold the tire on the wheel.
The wheel studs and nuts are designed for specific applications. All aluminum and some steel
wheels have wheel stud nuts with an enlarged nose. This enlarged nose is necessary to ensure
proper retention of the wheels. Do not use replacement studs or nuts with a different design or
lesser quality.

SUBJECT: Steering Wander Diagnosis
OVERVIEW: This bulletin provides a diagnostic procedure for steering wander.
MODELS: 1998-2001 (AB) Ram Van/Wagon
SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight
steering corrections are necessary to be able to keep the vehicle moving in a straight line.
Steering wander can be created by a number of different conditions including but not limited to the
following:
^ Non-factory installed options.
^ Tires or wheels of different size.
^ Aftermarket wheels.
^ Tires that have a belt that has shifted.
^ Incorrect tire pressure.
^ A vehicle that is carrying extra added weight (e.g. tool boxes).
^ Steering and/or suspension components that are worn or damaged.
^ Wheel bearings that are loose, worn, or damaged.
^ A vehicle that is not within alignment specifications.
NOTE:
UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS,
CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER.
The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering
system components are functioning as designed and are not the root cause of steering wander.
DIAGNOSIS:
1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may
cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to
exceed the front or rear Gross Axle Weight Rating (GAWR).
2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged
and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to
wander and should be replaced before continuing with the diagnosis.
3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove
box).
NOTE:
TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN
PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB
OR LIGHT LOAD CONDITIONS.
4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road
crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70
mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the
vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a
steering wander condition.
NOTE:
VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD
TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION
MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED
ROADS, ETC.).
5. Raise the vehicle on an appropriate lift.

Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 1100
6. Secure a dial indicator to the lower control arm. Position the dial indicator so that the tip of the
indicator contacts the inside face of the rotor (Figure 1).
7. Place your hands at the top and bottom of the tire/wheel assembly and push the tire/wheel
assembly inboard (Figure 2). Zero the dial indicator. With your hands at the top and bottom of the
tire/wheel assembly, pull the tire/wheel assembly outboard (Figure 3). Record the dial indicator
reading. Perform this procedure on both front wheel bearings and proceed to the next step if the
wheel bearing endplay exceeds 0.025 - 0.076 mm (0.001 - 0.003 in.). Proceed to Step 9 if
wheel-bearing endplay on both front wheel bearings are within specifications.
NOTE:
WHEEL BEARING INSPECTION AND ADJUSTMENT IS ONLY REQUIRED ON WHEEL
BEARINGS EXCEEDING 0.025 - 0.076 MM (0.001 - 0.003 IN.) ENDPLAY.
8. Remove the wheel bearing protective end cap, cotter pin, nut lock, nut, and washer from the
spindle. Inspect the wheel bearings. If it is determined that wheel bearing replacement is
necessary, refer to the appropriate Ram Van/Wagon Service Manual, Group 02, Wheel Bearings,
for removal and installation information. Reinstall the wheel bearings, washer, and adjustment nut if
the wheel bearings pass the inspection.
9. Using a torque wrench, tighten the wheel bearing adjustment nut to 54 N.m (40 ft. lbs.) while
rotating the tire/wheel assembly. Stop the wheel from rotating and loosen the nut. Using the
procedure identified in Steps 6 and 7 to measure endplay, adjust the front wheel bearing endplay
until 0.025 - 0.076 mm (0.001 - 0.003 in.) endplay has been achieved. Install the nut lock and a
new cotter pin.
10. Perform the Pre-Alignment inspection as identified in Group 02, Service Procedures, of the
appropriate Ram Van/Wagon Service Manual. Any worn steering and/or suspension component
must be replaced prior to performing an alignment.

Lifter / Lash Adjuster: Testing and Inspection
HYDRAULIC TAPPETS
Before disassembling any part of the engine to correct tappet noise, check the oil pressure. If
vehicle has no oil pressure gauge, install a reliable gauge at the pressure sending-unit. The
pressure should be between 207-552 kPa (30-80 psi) at 3,000 RPM. Check the oil level after the
engine reaches normal operating temperature. Allow 5 minutes to stabilize oil level, check dipstick.
The oil level in the pan should never be above the FULL mark or below the ADD OIL mark on
dipstick. Either of these two conditions could be responsible for noisy tappets.
OIL LEVEL HIGH
If oil level is above the FULL mark, it is possible for the connecting rods to dip into the oil. With the
engine running, this condition could create foam in the oil pan. Foam in oil pan would be fed to the
hydraulic tappets by the oil pump causing them to lose length and allow valves to seat noisily.
LOW
Low oil level may allow oil pump to take in air. When air is fed to the tappets, they lose length,
which allows valves to seat noisily. Any leaks on intake side of oil pump through which air can be
drawn will create the same tappet action. Check the lubrication system from the intake strainer to
the pump cover, including the relief valve retainer cap. When tappet noise is due to aeration, it may
be intermittent or constant, and usually more than one tappet will be noisy. When oil level and
leaks have been corrected, operate the engine at fast idle. Run engine for a sufficient time to allow
all of the air inside the tappets to be bled out.
TAPPET NOISE DIAGNOSIS
1. To determine source of tappet noise, operate engine at idle with cylinder head covers removed.
2. Feel each valve spring or rocker arm to detect noisy tappet. The noisy tappet will cause the
affected spring and/or rocker arm to vibrate or feel
rough in operation.
NOTE: Worn valve guides or cocked springs are sometimes mistaken for noisy tappets.
If such is the case, noise may be dampened by applying side thrust on the valve spring. If noise is
not appreciably reduced, it can be assumed the noise is in the tappet. Inspect the rocker arm push
rod sockets and push rod ends for wear.
3. Valve tappet noise ranges from light noise to a heavy click. A light noise is usually caused by
excessive leak-down around the unit plunger, or by
the plunger partially sticking in the tappet body cylinder. The tappet should be replaced. A heavy
click is caused by a tappet check valve not seating, or by foreign particles wedged between the
plunger and the tappet body. This will cause the plunger to stick in the down position. This heavy
click will be accompanied by excessive clearance between the valve stem and rocker arm as valve
closes. In either case, tappet assembly should be removed for inspection and cleaning.
4. The valve train generates a noise very much like a light tappet noise during normal operation.
Care must be taken to ensure that tappets are making
the noise. If more than one tappet seems to be noisy, it's probably not the tappets.

Fit all rods on a bank until completed. DO NOT alternate from one bank to another, because
connecting rods and pistons are not interchangeable from one bank to another. The bearing caps
are not interchangeable and should be marked at removal to ensure correct assembly. Each
bearing cap has a small V-groove across the parting face. When installing the lower bearing shell,
make certain that the V-groove in the shell is in line with the V-groove in the cap. This provides
lubrication of the cylinder wall in the opposite bank. The bearing shells must be installed so that the
tangs are in the machined grooves in the rods and caps. Limits of taper or out-of-round on any
crankshaft journals should be held to 0.025 mm (0.001 inch). Bearings are available in 0.025 mm
(0.001 inch), 0.051 mm (0.002 inch), 0.076 mm (0.003 inch), 0.254 mm (0.010 inch) and 0.305 mm

Connecting Rod Bearing: Service and Repair Connecting Rod Bearing Clearance
CONNECTING ROD BEARING CLEARANCE
Engine connecting rod bearing clearances can be determined by use of Plastigage, or equivalent.
The following is the recommended procedures for the use of Plastigage: 1. Remove oil film from
surface to be checked. Plastigage is soluble in oil. 2. Place a piece of Plastigage across the entire
width of the bearing cap shell. Position the Plastigage approximately 6.35 mm (1/4 inch) off center
and away from the oil holes. In addition, suspect areas can be checked by placing the Plastigage in
the suspect area.
3. The crankshaft must be turned until the connecting rod to be checked starts moving toward the
top of the engine. Only then should the rod cap with
Plastigage in place be assembled. Tighten the 3.9L, and 5.2L rod cap nut to 61 Nm (45 ft. lbs.)
torque. DO NOT rotate the crankshaft or the Plastigage may be smeared, giving inaccurate results.
4. Remove the bearing cap and compare the width of the flattened Plastigage with the scale
provided on the package. Plastigage generally comes in 2
scales (one scale is in inches and the other is a metric scale). Locate the band closest to the same
width. This band shows the amount of clearance. Differences in readings between the ends
indicate the amount of taper present. Record all readings taken (refer to Engine Specifications).
5. Plastigage is available in a variety of clearance ranges. The 0.025-0.076 mm (0.001-0.003 inch)
range is usually the most appropriate for checking
engine bearing clearances.

Piston: Description and Operation
PISTONS
The pistons are elliptically turned so that the diameter at the pin boss is less than its diameter
across the thrust face. This allows for expansion under normal operating conditions. Under
operating temperatures, expansion forces the pin bosses away from each other, causing the piston
to assume a more nearly round shape. All pistons are machined to the same weight, regardless of
size, to maintain piston balance. The piston pin rotates in the piston only and is retained by the
press interference fit of the piston pin in the connecting rod.

Piston Ring: Service and Repair
1. Measurement of end gaps:
a. Measure piston ring gap 2 inches from bottom of cylinder bore. An inverted piston can be used
to push the rings down to ensure positioning
rings squarely in the cylinder bore before measuring.
b. Insert feeler gauge in the gap. The top compression ring gap should be between 0.254-0.508
mm (0.010-0.020 inch). The second compression
ring gap should be between 0.508-0.762 mm (0.020-0.030 inch). The oil ring gap should be
0.254-1.270 mm (0.010-0.050 inch).
c. Rings with insufficient end gap may be properly filed to the correct dimension. Rings with excess
gaps should not be used.
2. Install rings and confirm ring side clearance:
a. Install oil rings being careful not to nick or scratch the piston. Install the oil control rings
according to instructions in the package. It is not
necessary to use a tool to install the upper and lower rails. Insert oil rail spacer first, then side rails.
Top Compression Ring Identification (Typical)
Compression Ring Chamfer Location (Typical)
b. Install the second compression rings using Installation Tool C-4184. The compression rings must
be installed with the identification mark face
up (toward top of piston) and chamfer facing down. An identification mark on the ring is a drill point,
a stamped letter "O", an oval depression or the word TOP.

Refacing Valve Seats
CAUTION: DO NOT un-shroud valves during valve seat refacing.
1. When refacing valve seats, it is important that, the correct size valve guide pilot be used for
reseating stones. A true and complete surface must be
obtained.
2. Measure the concentricity of valve seat using a. dial indicator. Total runout should not exceed
0.051 mm (0.002 inch) total indicator reading. 3. Inspect the valve seat with Prussian blue to
determine where the valve contacts the seat. To do this, coat valve seat LIGHTLY with Prussian
blue
then set valve in place. Rotate the valve with light, pressure. If the blue is transferred to the center
of valve face, contact is satisfactory. If the blue is transferred to the top edge of valve face, lower
valve seat, with a 15° stone. If the blue is transferred to bottom edge of valve face raise valve seat
with a 60° stone.
4. When seat is properly positioned the width of intake seats should be 1.016-1.524 mm
(0.040-0.060 inch). The width of the exhaust seats should be
1.524-2.032 mm (0.060-0.080 inch).
VALVE SPRING INSPECTION
Testing Valve Spring For Compression Length
Whenever valves have been removed for inspection, reconditioning or replacement, valve springs
should be tested. As an example the compression length of the spring to be tested is 1-5/16 inch.
Turn table of Universal Valve Spring Tester Tool until surface is in line with the 1-5/16 inch mark on
the threaded stud. Be sure the zero mark is to the front. Place spring over stud on the table and lift
compressing lever to set tone device. Pull on torque wrench until ping is heard. Take reading on
torque wrench at this instant. Multiply this reading by 2. This will give the spring load at test length.
Fractional measurements are indicated on the table for finer adjustments. Refer to specifications to
obtain specified height and allowable tensions. Discard the springs that do not meet specifications.

Drive Belt: Description and Operation
ACCESSORY DRIVE BELT/TENSION
The accessory drive components are operated by a single, crankshaft driven, serpentine drive belt.
An automatic belt tensioner is used to maintain correct belt tension at all times. Correct accessory
drive belt tension is required to be sure of optimum performance of belt driven engine accessories.
If specified tension is not maintained, belt slippage may cause; engine overheating, lack of power
steering assist, loss of air conditioning capacity, reduced generator output rate and greatly reduced
belt life. It is not necessary to adjust belt tension on any engine. All engines are equipped with an
automatic belt tensioner. The tensioner maintains correct belt tension at all times. Due to use of
this belt tensioner, do not attempt to use a belt tension gauge on any engine.

Drive Belt: Testing and Inspection
VISUAL DIAGNOSIS
Belt Ware Patterns
When diagnosing serpentine accessory drive belts, small cracks that run across the ribbed surface
of the belt from rib to rib, are considered normal. These are not a reason to replace the belt.
However, cracks running along a rib (not across) are not normal. Any belt with cracks running
along a rib must be replaced. Also replace the belt if it has excessive wear, frayed cords or severe
glazing. Refer to the Accessory Drive Belt Diagnosis charts for further belt diagnosis.
NOISE DIAGNOSIS
Noises generated by the accessory drive belt are most noticeable at idle. Before replacing a belt to
resolve a noise condition, inspect all of the accessory drive pulleys for alignment, glazing, or
excessive end play.

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Gauge >
Component Information > Description and Operation
Oil Pressure Gauge: Description and Operation
SYSTEM OPERATION
The oil pressure gauge gives an indication of the engine oil pressure. The instrument cluster
circuitry controls the gauge pointer position. The instrument cluster circuitry calculates the proper
gauge pointer position based upon engine oil pressure messages received from the Powertrain
Control Module (PCM) on the Chrysler Collision Detection (CCD) data bus.
The PCM uses an input from the engine oil pressure sensor and internal programming to decide
what engine oil pressure messages are required. The PCM then sends the proper messages to the
instrument cluster on the CCD data bus. If the PCM messages indicate that oil pressure is too low,
the instrument cluster circuitry moves the gauge needle to the 0 PSI graduation on the gauge face,
turns on the Check Gauges lamp, and sends a chime tone request to the Central Timer Module
(CTM). If the PCM messages indicate that oil pressure is too high, the instrument cluster circuitry
moves the gauge needle to the 110 PSI graduation on the gauge face.
The engine oil pressure sensor is installed in a threaded hole that penetrates an oil passage of the
engine. The engine oil pressure sensor contains a flexible diaphragm and a variable resistor coil.
The diaphragm moves in response to changes in the engine oil pressure, which changes the
internal electrical resistance of the sensor.

Oil Pressure Gauge: Testing and Inspection
If the problem being diagnosed is related to oil pressure gauge accuracy, be certain to confirm that
the problem is with the gauge and not with the engine oiling system performance. The actual
engine oil pressure should be checked with a test gauge and compared to the instrument cluster oil
pressure gauge readings before you proceed with gauge diagnosis.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
NOTE: Increased oil pressure gauge needle activity may be noted with this instrument cluster than
with previous designs. This increased needle activity is due to changes that were made to the
instrument cluster software that are intended to make the gauge more responsive, and not due to
any problem with the engine oiling or oil pressure gauge systems. No attempt at service of these
systems should be made, unless the oil pressure gauge readings remain in the high end or the low
end of the normal range.
Diagnosis of the oil pressure sensor and circuit, the Chrysler Collision Detection (CCD) data bus,
and/or the Powertrain Control Module (PCM) should be performed with a DRB scan tool. For
further diagnosis of the oil pressure gauge and the instrument cluster circuitry, refer to Instrument
Panel/Testing and Inspection. See: Instrument Panel, Gauges and Warning Indicators/Instrument
Cluster / Carrier/Testing and Inspection

THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 09-06-99, DATED SEP.10,
1999, WHICH SHOULD BE REMOVED FROM YOUR FILES. THIS IS A COMPLETE REVISION
AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS.
SUBJECT: Spark Knock And Engine Oil Consumption Due To Intake Manifold Pan Gasket Oil
Leak
OVER VIEW: This bulletin involves the replacement of the engine intake manifold plenum pan
gasket.
NOTE:
THIS BULLETIN APPLIES TO VEHICLE EQUIPPED WITH A 3.9L, 5.2L. OR 5.9L GASOLINE
ENGINE.
SYMPTOM/CONDITION: An engine intake manifold plenum pan gasket oil leak may occur on
some V-6 and V-8 style engines. The oil leak is internal to the engine so no external oil leakage will
be present. Two symptoms of this oil leak condition may be present. The vehicle operator may
experience an engine spark knock during acceleration and/or an increase in the amount of engine
oil consumed by the engine.
DIAGNOSIS: Make sure Technical Service Bulletin (TSB) 18-48-98 has been performed.
NOTE:
IT IS IMPORTANT THAT THE COIL AND SPARK PLUG WIRES ARE ROUTED EXACTLY AS
SPECIFIED IN TSB 18-48-98 TO ACHIEVE THE MOST BENEFIT.
Inspect the Positive Crankcase Ventilation (PCV) valve. Shake the PCV valve to verify that the
pintle inside of the PCV valve is free. Replace the PVC if the pintle is not free.
If the intake manifold plenum pan gasket is leaking, an additional vacuum source will be created
inside of the engine at the location of the pan gasket leakage. Engine combustion blow-by gases,
oil vapor, and air from the crankcase filter/breather may be drawn past the leaking pan gasket and
into the intake manifold. In most cases when this condition occurs, an engine at idle will create the
highest vacuum and lowest amount of engine blow-by.
1. Allow the engine to reach normal operating temperature.
2. Stop the engine.
3. Disconnect the breather hose from the air cleaner.

Technical Service Bulletins > Customer Interest for Intake Manifold: > 09-05-00 > Feb > 00 > Engine - Spark Knock/Oil
Consumption > Page 1340
4. Attach a vacuum/pressure gauge to the end of the breather hose (Figure 1).
5. Disconnect the PCV valve hose from the intake manifold.
6. Seal off the intake manifold PCV valve hose port opening.
7. Seal off the open end of the PCV valve hose (Figure 2).
NOTE:
DURING THIS DIAGNOSIS, IT WOULD BE NORMAL FOR THE ENGINE TO DEVELOP
PRESSURE WITHIN THE ENGINE CRANKCASE. THIS IS DUE TO THE NORMAL PROCESS
OF EXHAUST BLOW-BY GASES LEAKING PAST THE ENGINE PISTON RINGS AND
ACCUMULATING IN THE ENGINE CRANKCASE. DO NOT ALLOW MORE THAN 3 PSI (20.7
kpa) OF PRESSURE TO BUILD WITHIN THE ENGINE WHEN PERFORMING THE FOLLOWING
DIAGNOSTIC PROCEDURE.
8. Start the warmed engine and observe the vacuum gauge.

Technical Service Bulletins > Customer Interest for Intake Manifold: > 09-05-00 > Feb > 00 > Engine - Spark Knock/Oil
Consumption > Page 1341
9. Allow the engine to idle for approximately 30 seconds. Do not allow more than 3 psi (20.7 kPa)
of pressure to develop in the engine crankcase.
10. If the attached vacuum / pressure gauge does not indicate that a vacuum is present in the
engine crankcase, then the intake manifold plenum pan gasket is good and no further internal
engine vacuum leak diagnosis is required.
11. If an internal vacuum leak is present then perform the Repair Procedure.

AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS.
SUBJECT: Spark Knock And Engine Oil Consumption Due To Intake Manifold Pan Gasket Oil
Leak
OVER VIEW: This bulletin involves the replacement of the engine intake manifold plenum pan
gasket.
NOTE:
THIS BULLETIN APPLIES TO VEHICLE EQUIPPED WITH A 3.9L, 5.2L. OR 5.9L GASOLINE
ENGINE.
SYMPTOM/CONDITION: An engine intake manifold plenum pan gasket oil leak may occur on
some V-6 and V-8 style engines. The oil leak is internal to the engine so no external oil leakage will
be present. Two symptoms of this oil leak condition may be present. The vehicle operator may
experience an engine spark knock during acceleration and/or an increase in the amount of engine
oil consumed by the engine.
DIAGNOSIS: Make sure Technical Service Bulletin (TSB) 18-48-98 has been performed.
NOTE:
IT IS IMPORTANT THAT THE COIL AND SPARK PLUG WIRES ARE ROUTED EXACTLY AS
SPECIFIED IN TSB 18-48-98 TO ACHIEVE THE MOST BENEFIT.
Inspect the Positive Crankcase Ventilation (PCV) valve. Shake the PCV valve to verify that the
pintle inside of the PCV valve is free. Replace the PVC if the pintle is not free.
If the intake manifold plenum pan gasket is leaking, an additional vacuum source will be created
inside of the engine at the location of the pan gasket leakage. Engine combustion blow-by gases,
oil vapor, and air from the crankcase filter/breather may be drawn past the leaking pan gasket and
into the intake manifold. In most cases when this condition occurs, an engine at idle will create the
highest vacuum and lowest amount of engine blow-by.
1. Allow the engine to reach normal operating temperature.
2. Stop the engine.
3. Disconnect the breather hose from the air cleaner.

4. Attach a vacuum/pressure gauge to the end of the breather hose (Figure 1).
5. Disconnect the PCV valve hose from the intake manifold.
6. Seal off the intake manifold PCV valve hose port opening.
7. Seal off the open end of the PCV valve hose (Figure 2).
NOTE:
DURING THIS DIAGNOSIS, IT WOULD BE NORMAL FOR THE ENGINE TO DEVELOP
PRESSURE WITHIN THE ENGINE CRANKCASE. THIS IS DUE TO THE NORMAL PROCESS
OF EXHAUST BLOW-BY GASES LEAKING PAST THE ENGINE PISTON RINGS AND
ACCUMULATING IN THE ENGINE CRANKCASE. DO NOT ALLOW MORE THAN 3 PSI (20.7
kpa) OF PRESSURE TO BUILD WITHIN THE ENGINE WHEN PERFORMING THE FOLLOWING
DIAGNOSTIC PROCEDURE.
8. Start the warmed engine and observe the vacuum gauge.

9. Allow the engine to idle for approximately 30 seconds. Do not allow more than 3 psi (20.7 kPa)
of pressure to develop in the engine crankcase.
10. If the attached vacuum / pressure gauge does not indicate that a vacuum is present in the
engine crankcase, then the intake manifold plenum pan gasket is good and no further internal
engine vacuum leak diagnosis is required.
11. If an internal vacuum leak is present then perform the Repair Procedure.

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Lamps and Indicators - Engine > Oil Pressure Gauge
> Component Information > Description and Operation
Oil Pressure Gauge: Description and Operation
SYSTEM OPERATION
The oil pressure gauge gives an indication of the engine oil pressure. The instrument cluster
circuitry controls the gauge pointer position. The instrument cluster circuitry calculates the proper
gauge pointer position based upon engine oil pressure messages received from the Powertrain
Control Module (PCM) on the Chrysler Collision Detection (CCD) data bus.
The PCM uses an input from the engine oil pressure sensor and internal programming to decide
what engine oil pressure messages are required. The PCM then sends the proper messages to the
instrument cluster on the CCD data bus. If the PCM messages indicate that oil pressure is too low,
the instrument cluster circuitry moves the gauge needle to the 0 PSI graduation on the gauge face,
turns on the Check Gauges lamp, and sends a chime tone request to the Central Timer Module
(CTM). If the PCM messages indicate that oil pressure is too high, the instrument cluster circuitry
moves the gauge needle to the 110 PSI graduation on the gauge face.
The engine oil pressure sensor is installed in a threaded hole that penetrates an oil passage of the
engine. The engine oil pressure sensor contains a flexible diaphragm and a variable resistor coil.
The diaphragm moves in response to changes in the engine oil pressure, which changes the
internal electrical resistance of the sensor.

Oil Pressure Gauge: Testing and Inspection
If the problem being diagnosed is related to oil pressure gauge accuracy, be certain to confirm that
the problem is with the gauge and not with the engine oiling system performance. The actual
engine oil pressure should be checked with a test gauge and compared to the instrument cluster oil
pressure gauge readings before you proceed with gauge diagnosis.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
NOTE: Increased oil pressure gauge needle activity may be noted with this instrument cluster than
with previous designs. This increased needle activity is due to changes that were made to the
instrument cluster software that are intended to make the gauge more responsive, and not due to
any problem with the engine oiling or oil pressure gauge systems. No attempt at service of these
systems should be made, unless the oil pressure gauge readings remain in the high end or the low
end of the normal range.
Diagnosis of the oil pressure sensor and circuit, the Chrysler Collision Detection (CCD) data bus,
and/or the Powertrain Control Module (PCM) should be performed with a DRB scan tool. For
further diagnosis of the oil pressure gauge and the instrument cluster circuitry, refer to Instrument
Panel/Testing and Inspection. See: Instrument Panel, Gauges and Warning Indicators/Instrument
Cluster / Carrier/Testing and Inspection

Cylinder Head Gasket: Testing and Inspection
FAILURE DIAGNOSIS
A leaking engine cylinder head gasket usually results in loss of power, loss of coolant, and engine
misfiring.
An engine cylinder head gasket leak can be located between adjacent cylinders or between a
cylinder and the adjacent water jacket. An engine cylinder head gasket leaking between adjacent cylinders is indicated by a loss of power
and/or engine misfire.
- An engine cylinder head gasket leaking between a cylinder and an adjacent water jacket is
indicated by coolant foaming or overheating and loss of coolant.
Cylinder To Cylinder Leakage Test To determine if an engine cylinder head gasket is leaking
between adjacent cylinders, follow the procedures outlined in Cylinder Compression Pressure Test.
An engine cylinder head gasket leaking between adjacent cylinders will result in approximately a
50-70% reduction in compression pressure.
Cylinder To Water Jacket Leakage Test
WARNING: Use extreme caution when the engine is operating. Do not stand in a direct line with
the fan. Do not put your hands near the pulleys, belts, oft the fan. Do not wear loose clothing.
Remove the radiator cap.
Start the engine and allow it to warm up until the engine thermostat opens.
If a large combustion/compression pressure leak exists, bubbles will be visible in the coolant.
If bubbles are not visible, install a radiator pressure tester and pressurize the coolant system.
If a cylinder is leaking combustion pressure into the water jacket, the tester pointer will pulsate with
every combustion stroke of the cylinder.

SUBJECT: Spark Knock And Engine Oil Consumption Due To Intake Manifold Pan Gasket Oil
Leak
OVER VIEW: This bulletin involves the replacement of the engine intake manifold plenum pan
gasket.
NOTE:
THIS BULLETIN APPLIES TO VEHICLE EQUIPPED WITH A 3.9L, 5.2L. OR 5.9L GASOLINE
ENGINE.
SYMPTOM/CONDITION: An engine intake manifold plenum pan gasket oil leak may occur on
some V-6 and V-8 style engines. The oil leak is internal to the engine so no external oil leakage will
be present. Two symptoms of this oil leak condition may be present. The vehicle operator may
experience an engine spark knock during acceleration and/or an increase in the amount of engine
oil consumed by the engine.
DIAGNOSIS: Make sure Technical Service Bulletin (TSB) 18-48-98 has been performed.
NOTE:
IT IS IMPORTANT THAT THE COIL AND SPARK PLUG WIRES ARE ROUTED EXACTLY AS
SPECIFIED IN TSB 18-48-98 TO ACHIEVE THE MOST BENEFIT.
Inspect the Positive Crankcase Ventilation (PCV) valve. Shake the PCV valve to verify that the
pintle inside of the PCV valve is free. Replace the PVC if the pintle is not free.
If the intake manifold plenum pan gasket is leaking, an additional vacuum source will be created
inside of the engine at the location of the pan gasket leakage. Engine combustion blow-by gases,
oil vapor, and air from the crankcase filter/breather may be drawn past the leaking pan gasket and
into the intake manifold. In most cases when this condition occurs, an engine at idle will create the
highest vacuum and lowest amount of engine blow-by.
1. Allow the engine to reach normal operating temperature.
2. Stop the engine.
3. Disconnect the breather hose from the air cleaner.

4. Attach a vacuum/pressure gauge to the end of the breather hose (Figure 1).
5. Disconnect the PCV valve hose from the intake manifold.
6. Seal off the intake manifold PCV valve hose port opening.
7. Seal off the open end of the PCV valve hose (Figure 2).
NOTE:
DURING THIS DIAGNOSIS, IT WOULD BE NORMAL FOR THE ENGINE TO DEVELOP
PRESSURE WITHIN THE ENGINE CRANKCASE. THIS IS DUE TO THE NORMAL PROCESS
OF EXHAUST BLOW-BY GASES LEAKING PAST THE ENGINE PISTON RINGS AND
ACCUMULATING IN THE ENGINE CRANKCASE. DO NOT ALLOW MORE THAN 3 PSI (20.7
kpa) OF PRESSURE TO BUILD WITHIN THE ENGINE WHEN PERFORMING THE FOLLOWING
DIAGNOSTIC PROCEDURE.
8. Start the warmed engine and observe the vacuum gauge.

9. Allow the engine to idle for approximately 30 seconds. Do not allow more than 3 psi (20.7 kPa)
of pressure to develop in the engine crankcase.
10. If the attached vacuum / pressure gauge does not indicate that a vacuum is present in the
engine crankcase, then the intake manifold plenum pan gasket is good and no further internal
engine vacuum leak diagnosis is required.
11. If an internal vacuum leak is present then perform the Repair Procedure.

NOTE: To access timing chain Refer to Timing Cover.
1. Place a scale next to the timing chain so that any movement of the chain may be measured. 2.
Place a torque wrench and socket over camshaft sprocket attaching bolt. Apply torque in the
direction of crankshaft rotation to take up slack; 41
Nm (30 ft. lbs.) torque with cylinder head installed or 20 Nm (15 ft. lbs.) torque with cylinder head
removed. With a torque applied to the camshaft sprocket bolt, crankshaft should not be permitted
to move. It may be necessary to block the crankshaft to prevent rotation.

3. Hold a scale with dimensional reading even with the edge of a chain link. With cylinder heads
installed, apply 14 Nm (30 ft. lbs.) torque in the
reverse direction. With the cylinder heads removed, apply 20 Nm (15 ft. lbs.) torque in the reverse
direction. Note the amount of chain movement.
4. Install a new timing chain, if its movement exceeds 3.175 mm (1/8 inch). 5. If chain is not
satisfactory, remove camshaft sprocket attaching bolt and remove timing chain with crankshaft and
camshaft sprockets. 6. Place both camshaft sprocket and crankshaft sprocket on the bench with
timing marks on exact imaginary center line through both camshaft and
crankshaft bores.
7. Place timing chain around both sprockets. 8. Turn crankshaft and camshaft to line up with
keyway location in crankshaft sprocket and in camshaft sprocket. 9. Lift sprockets and chain (keep
sprockets tight against the chain in position as described).
Alignment Of Timing Marks
10. Slide both sprockets evenly over their respective shafts and use a straightedge to check
alignment of timing marks. 11. Install the camshaft bolt. Tighten the bolt to 47 Nm (35 ft. lbs.)
torque. 12. Check camshaft end play. The end play should be 0.051-0.152 mm (0.002-0.006 inch)
with a new thrust plate and up to 0.254 mm (0.010 inch)
with a used thrust plate. If not within these limits install a new thrust plate.

Fuel Pressure: Capacity Specifications
NOTE: Before performing this test, verify fuel pump pressure by performing the Fuel Pump
Pressure Test. Use this test in conjunction with the Fuel Pressure Leak Down Test.
1. Release fuel system pressure.
- Refer to the Fuel Pressure Release Procedure.
2. Disconnect the fuel supply line at fuel rail.
- Some engines may require air cleaner housing removal before line disconnection.
3. Connect appropriate Fuel Line Pressure Test Adapter Tool Hose (number 6631, 6923, 6541 or
6539) into disconnected fuel supply line.
- Insert other end of Adaptor Tool hose into a graduated container.
4. Remove the fuel fill cap. 5. To activate fuel pump and pressurize system, obtain DRB scan tool
and actuate ASD Fuel System Test. 6. A good fuel pump will deliver at least 1/4 liter of fuel in 7
seconds.
- Do not operate fuel pump for longer than 7 seconds with fuel line disconnected as fuel pump
module reservoir may run empty.
a. If capacity is lower than specification, but fuel pump can be heard operating through fuel fill cap
opening, check for a kinked/damaged fuel
supply line somewhere between fuel rail and fuel pump module.
b. If line is not kinked/damaged, and fuel pressure is OK, but capacity is low, replace fuel filter/ fuel
pressure regulator. The filter/regulator may be serviced separately on certain applications.
- Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information.

Fuel Pressure: Testing and Inspection Fuel Pressure Leak Down Test
Fig 9 Connecting Adaptor Tool -- Typical
Fig. 8 Installing Adapter Tool And Pressure Gauge
NOTE: Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity
Test.
Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational.
After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid
gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure
that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the
electric fuel pump is activated, fuel pressure should immediately rise to specification.
Abnormally long periods of cranking to restart a hot engine that has been shut down for a short
period of time may be caused by: Fuel pressure bleeding past a fuel injector(s).
- Fuel pressure bleeding past the check valve in the fuel pump module.
1. Disconnect the fuel inlet line at fuel rail.
- On some engines, air cleaner housing removal may be necessary before fuel line disconnection.
2. Connect the appropriate Fuel Line Pressure Test Adapter Tool (number 6539, 6631, 6541 or
6923) between the disconnected fuel line and fuel rail
(Fig. 9) or (Fig. 10).
3. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test
port on the appropriate Adaptor Tool.
- The fittings on both tools must be in good condition and free from any small leaks before
performing the proceeding test.
4. Start engine and bring to normal operating temperature.

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Fuel
Pressure > System Information > System Diagnosis > Fuel Pressure Leak Down Test > Page 1452
5. Observe test gauge. Normal operating pressure should be 339 kPa +/- 34 kPa (49.2 psi +/- 5
psi). 6. Shut engine off. 7. Pressure should not fall below 30 psi for five minutes. 8. If pressure falls
below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module,
or a fuel tube/line is leaking. 9. Again, start engine and bring to normal operating temperature.
10. Shut engine off. 11. Testing for fuel injector or fuel rail leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on
Adapter Tool.
- If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking.
12. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T"
on Adapter Tool.
- If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line.
- If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump
or filter/ regulator may be leaking.
NOTE: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A
slow loss of pressure usually indicates a defective check valve in the electric fuel pump.
The electric fuel pump is not serviced separately -- Replace the fuel pump module assembly. The
filter/ regulator may be replaced separately on certain applications. Refer to Fuel Filter/Fuel
Pressure Regulator Removal/installation for additional information.

Fuel Pressure: Testing and Inspection Fuel Pressure Test
Fuel Pressure Test Gauge
NOTE: Use this test in conjunction with the Fuel Pump Capacity Test, Fuel Pressure Leak Down
Test, fuel pump amperage test.
Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow hack into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational. After the vehicle has cooled down fuel pressure may drop to 0 psi (cold fluid
contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel
injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal
condition. When the electric fuel pump is activated, fuel pressure should immediately rise to
specification.
All fuel systems are equipped with a fuel tank module mounted, combination fuel filter/fuel pressure
regulator. The fuel pressure regulator is not controlled by engine vacuum.
WARNING: The fuel system is under constant fuel pressure even with the engine off. Before
disconnecting fuel line at fuel rail, this pressure must be released. Refer to the fuel system
pressure release procedure.
NOTE: To perform this test you will need to remove the engine cover.
1. Remove the protective cap at the fuel rail test port. Connect the 0-414 kPa (0-60 psi) fuel
pressure gauge (from gauge set 5069) to the test port
pressure fitting on the fuel rail.
2. Start and warm the engine and note pressure gauge reading. Fuel pressure should be 3.39 kPa
+/- 34 kPa (49.2 psi +/- 5 psi) at idle. 3. If engine runs but pressure is below 44.2 psi, check for a
kinked fuel supply line somewhere between fuel rail and fuel pump module. If line is not
kinked, replace fuel pump module assembly. Refer to Fuel Pump Removal/Installation.
4. If operating pressure is above 54.2 psi, electric fuel pump is OK, but fuel pressure regulator is
defective. Replace fuel filter/fuel pressure regulator.
Certain filter/regulators may be serviced separately and some require the replacement of the fuel
pump module assembly Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for more
information.

Ignition Cable: Description and Operation
SYSTEM OPERATION
Spark plug cables are sometimes referred to as secondary ignition wires. These cables transfer
electrical current from the ignition coil(8) and/or distributor, to individual spark plugs at each
cylinder. The resistive spark plug cables are of nonmetallic construction. The cables provide
suppression of radio frequency emissions from the ignition system.

Cable > Component Information > Technical Service Bulletins > Page 1516
Ignition Cable: Testing and Inspection
Heat Shields
Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and
spark plugs. Terminals should be fully seated. The insulators should be in good condition and
should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are
cracked or torn must be replaced.
Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the
cables dry. Check for brittle or cracked insulation.
Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable
boot and spark plug . These shields protect the spark plug boots from damage (due to intense
engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug
cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat
shield.
Testing
When testing secondary cables for damage with an oscilloscope, follow the instructions of the
equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as
follows:
CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during
testing. This may cause possible heat damage to the catalytic converter. Total test time must not
exceed ten minutes.
With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to
a good engine ground. If the cable and spark plug are in good condition, the engine rpm should
drop and the engine will run poorly If engine rpm does not drop, the cable and/or spark plug may
not be operating properly and should be replaced. Also check engine cylinder compression.
With the engine not running, connect one end of a test probe to a good ground. Start the engine
and run the other end of the test probe along the entire length of all spark plug cables. If cables are
cracked or punctured, there will be a noticeable spark jump from the damaged area to the test
probe. The cable running from the ignition coil to the distributor cap can be checked in the same
manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This
can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket.
Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped,
remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from
spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode
in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable
from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not
within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable.
Test all spark plug cables in this manner.
Spark Plug Cable Resistance MINIMUM = MAXIMUM 250 Ohms Per Inch = 1000 Ohms Per Inch
3000 Ohms Per Foot = 12,000 Ohms Per Foot
To test ignition coil-to-distributor cap cab]e, do not remove the cable from the cap. Connect
ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of
cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart,
remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable.
If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace
the cable. Inspect the ignition coil tower for cracks, burns or corrosion.

REMOVAL AND INSTALLATION
Cable Removal
CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap,
twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off
with a steady, even force.
Engine Firing Order
Install cables into the proper engine cylinder firing order.
When replacing the spark plug and coil cables, route the cables correctly and secure in the proper
retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It
could also cause cross ignition of the plugs or short circuit the cables to ground.
When installing new cables, make sure a positive connection is made. A snap should be felt when
a good connection is made between the plug cable and the distributor cap tower.

Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for
cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the
inside (caused by condensation entering the cap through cracks). Replace any cap that displays
charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will
indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence
of mechanical interference with the rotor tip.

Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip.
Also check for evidence of mechanical interference with the cap. Some charring is normal on the
end of the metal tip. The silicone-dielectric-varnish-compound applied to the rotor tip for radio
interference noise suppression, will appear charred. This is normal. Do not remove the charred
compound. Test the spring for insufficient tension. Replace a rotor that displays any of these
adverse conditions.

Spark Plug: Description and Operation
SYSTEM OPERATION
All engines use resistor type spark plugs. Remove the spark plugs and examine them for burned
electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in
which they were removed from the engine. A single plug displaying an abnormal condition indicates
that a problem exists in the corresponding cylinder.
Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or
oil fouled.

Spark Plug: Testing and Inspection
Normal Operating
Spark Plug Cable Resistance
The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is
evident with most grades of commercial gasoline. There will not be evidence of electrode burning.
Gap growth will not average more than approximately 0.025 mm (0.001 in) per 1600 km (1000
miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the
electrodes filed, have the gap set and then be installed.
Some fuel refiners in several areas of the United States have introduced a manganese additive
(MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug
to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by
coolant in the combustion chamber. Spark plug performance is not affected by MMT deposits.
Cold Fouling/Carbon Fouling
Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are
basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking
valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be
caused by a clogged air cleaner element or repeated short operating times (short trips).
Wet Fouling Or Gas Fouling
A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings,
leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently
overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This
condition can usually be resolved by cleaning and reinstalling the fouled plugs.
Oil Or Ash Encrusted
Oil Or Ash Encrusted
If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of
oil entry into that particular combustion chamber.
Electrode Gap Bridging

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark
Plug > Component Information > Specifications > Page 1531
Electrode Gap Bridging
Electrode gap bridging may be traced to loose deposits in the combustion chamber. These
deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is
suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between
electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be
cleaned using standard procedures.
Scavenger Deposits
Scavenger Deposit
Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is
a normal condition caused by chemical additives in certain fuels. These additives are designed to
change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that
accumulation on the ground electrode and shell area may be heavy, but the deposits are easily
removed. Spark plugs with scavenger deposits can be considered normal in condition and can be
cleaned using standard procedures.
Chipped Electrode Insulator
Chipped Electrode Insulator
A chipped electrode insulator usually results from bending the center electrode while adjusting the
spark plug electrode gap. Under certain conditions, severe detonation can also separate the
insulator from the center electrode. Spark plugs with this condition must be replaced.
Preignition Damage

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark
Plug > Component Information > Specifications > Page 1532
Preignition Damage
Preignition damage is usually caused by excessive combustion chamber temperature. The center
electrode dissolves first and the ground electrode dissolves somewhat latter. Insulators appear
relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine.
Determine if ignition timing is over advanced or if other operating conditions are causing engine
overheating. (The heat range rating refers to the operating temperature of a particular type spark
plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon
the thickness and length of the center electrodes porcelain insulator.)
Spark Plug Overheating
Spark Plug Overheating
Overheating is indicated by a white or gray center electrode insulator that also appears blistered.
The increase in electrode gap will be considerably in excess of 0.001 inch per 1000 miles of
operation. This suggests that a plug with a cooler heat range rating should be used. Over
advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug
overheating.

Spark Plug: Service and Repair
Heat Shields
Spark plug cable heat shields are pressed into the cylinder head to surround each cable boot and
spark plug.
If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides
of shield for removal. Each shield is slotted to allow for compression and removal. To install the
shields, align shield to machined opening in cylinder head and tap into place with a block of wood.
PLUG REMOVAL 1. Remove engine cover. 2. Always remove spark plug or ignition coil cables by
grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady
motion. Never pull directly on the cable. Internal damage to cable will result,
3. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area
around the spark plug. This will help prevent
foreign material from entering the combustion chamber.
4. Remove the spark plug using a quality socket with a rubber or foam insert. 5. Inspect the spark
plug condition.
Plug Cleaning The plugs may be cleaned using commercially available spark plug cleaning
equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before
adjusting gap.
CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will
remain on the spark plug insulator arid will cause plug misfire.
Plug Gap Adjustment Check the spark plug gap with a gap gauge tool. If the gap is not correct,
adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center
electrode.
Spark Plug Gap V-8 Engines: 1.01 mm (.040 in).
PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder
head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be
damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in
a change in the spark plug gap or a cracked porcelain insulator.
when replacing the spark plug and ignition coil cables, route the cables correctly and secure them
in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce
ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground.
1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark
plugs to 35-41 N.m (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs.

Water Pump: Description and Operation
A centrifugal water pump circulates coolant through the water jackets, passages, intake manifold,
radiator core, cooling system hoses and heater core. The pump is driven from the engine
crankshaft by a drive belt.
The water pump impeller is pressed onto the rear of a shaft that rotates in a bearing pressed into
the water pump body. The body has a small hole for ventilation. The water pump seals are
lubricated by antifreeze in the coolant mixture. Additional lubrication is not necessary.
A quick test to determine if pump is working is to check if heater warms properly. A defective water
pump will not be able to circulate heated coolant through the long heater hose to the heater core.
The water pump on all models can be removed without discharging the air conditioning system (if
equipped).

Coolant: Fluid Type Specifications
The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle
operating conditions. The recommended mixture of 50/50 ethylene-glycol and water will provide
protection against freezing to -37° C (-35° F). The antifreeze concentration must always be a
minimum of 44%, year round, in all climates. If percentage is lower than 44%, engine parts may be
eroded by cavitation, and cooling system components may be severely damaged by corrosion.
Maximum protection against freezing is provided with a 68% antifreeze concentration, which
prevents freezing down to -67.7° C (-90° F). A higher percentage will freeze at a warmer
temperature. Also, a higher percentage of antifreeze can cause the engine to overheat because the
specific heat of antifreeze is lower than that of water.
100 Percent Ethylene-Glycol Should Not Be Used
Use of 100 Percent Ethylene-Glycol will cause formation of additive deposits in the system, as the
corrosive inhibitive additives in ethylene-glycol require the presence of water to dissolve. The
deposits act as insulation, causing temperatures to rise as high as 149° C (300° F). this
temperature is hot enough to melt plastic and soften solder. The increased temperature can result
in engine detonation. In addition, 100 % ethylene-glycol freezes at 22° C (-8° F).
Propylene-Glycol Formulations Should Not Be Used
Propylene-glycol formulations do not meet the required specifications. It's overall effective
temperature range is smaller than that of ethylene-glycol. The freeze point of 50/50
propylene-glycol and water is -32° C (-26° F), 5 degrees higher than ethylene-glycol's freeze point.
The boiling point (protection against summer boil-over) of propylene-glycol is 125° C (257° F) at
96.5 kPa (14 PSI), compared to 128° C (263° F) for ethylene-glycol. Use of propylene-glycol can
result in boil-over and freeze up. Propylene-Glycol also has a poorer heat transfer characteristics
than ethylene-glycol. This can increase cylinder head temperatures under certain conditions.
Propylene-Glycol/Ethylene-Glycol Mixtures Should Not Be Used
Propylene-glycol/ethylene-glycol mixtures can cause the destabilization of various corrosion
inhibitors, causing damage to the coling system components. Also, once ethylene-glycol and
propylene-glycol based coolants are mixed in the vehicle, conventional methods of determining the
freeze point will not be accurate. Both the refractive index and specific gravity differ between the
ethylene-glycol and propylene-glycol.
CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can
cause problems associated with 100 percent ethylene-glycol.

ETHYLENE-GLYCOL MIXTURES
The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle
open ating conditions. The recommended mixture of 50/50 ethylene-glycol and water will provide
protection against freezing to -37 deg. C 05 deg. F). The anti-freeze concentration must always be
a minimum of 44 percent, year-round in all climates. If percentage is lower than 44 percent, engine
parts may be eroded by cavitation, and cooling system components may be severely damaged by
corrosion. Maximum protection against freezing is provided with a 68 percent antifreeze

100 Percent Ethylene-Glycol Should Not Be Used in Chrysler Vehicles Use of 100 percent
ethylene-glycol will cause formation of additive deposits in the system, as the corrosion inhibitive
additives in ethylene-glycol require the presence of water to dissolve. The deposits act as
insulation, causing temperatures to rise to as high as 149 deg. C (300) deg. F). This temperature is
hot, enough to melt plastic and soften solder. The increased temperature can result in engine
detonation. In addition, 100 percent ethylene-glycol freezes at 22 deg. C (-8 deg. F).
Propylene-glycol Formulations Should Not Be Used in Chrysler Vehicles Propylene-glycol
formulations do not meet Chrysler coolant specifications. It's overall effective temperature range is
smaller than that of ethylene-glycol. The freeze point of 50/50 propylene-glycol and water is -32
deg. C (-26 deg. F). 5 deg. C higher than ethylene-glycol's freeze point. The boiling point
(protection against summer boil-over) of propylene-glycol is 125 deg. C (257 deg. F ) at 96.5 kPa
(14 psi), compared to 128 deg. C (263 deg. F) for ethylene-glycol. Use of propylene-glycol can
result in boil-over or freeze-up in Chrysler vehicles, which are designed for ethylene-glycol.
Propylene glycol also has poorer heat transfer characteristics than ethylene glycol. This can
increase cylinder head temperatures under certain conditions.
Propylene-glycol/Ethylene-glycol Mixtures Should Not Be Used in Chrysler Vehicles
Propylene-glycol/ethylene-glycol Mixtures can cause the destabilization of various corrosion

NO: 07-05-98
GROUP: Cooling
DATE: Sep. 4, 1998
SUBJECT:
Engine Cooling Fan Noise
MODELS:
1998 - 1999 (AB) Ram Van/Wagon 1997 - 1999 (AN) Dakota 1998 - 1999 (DN) Durango
DISCUSSION:
Some vehicles may exhibit an engine cooling fan "roar" noise. This noise is created by a large
cooling fan that is required to provide optimum cooling for low vehicle speed operation in hot
weather conditions and for heavy trailer towing. Since the large cooling fan is unnecessary in most
operating conditions, these vehicles are also equipped with viscous fan drives that allow the fan to
operate at variable speeds based upon temperature loads. The viscous fan drive will engage the
fan for maximum cooling when temperatures are high and allow the fan to operate at slower
speeds when temperatures are low. In addition, at engine start-up, the viscous fan drive engages
the fan for maximum cooling until the fluid in the viscous clutch can dissipate out of the clutch drive
grooves allowing the fan to operate at a slower speed.
Because of the viscous fan drive, the noise may occur during high temperature conditions and for
the first 1-2 minutes of operation. Due to the roar of the fan, customers may also complain of a
perceived loss of power, automatic transmission slippage, or that the transmission is slaying into a
low gear too long (delayed upshift).
Customers concerned about this noise should be advised that this condition is normal and no
repair attempts should be made.

NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 3.9L, 5.2L, OR 5.9L GASOLINE
ENGINE BUILT AFTER JANUARY 5, 1998 (MDH 0105XX).
DISCUSSION:
Vehicles built after January 5, 1998 have the water pump pulley pressed onto the water pump hub
shaft. As in previous models, the viscous fan drive is threaded onto the water pump hub shaft.
Because the pulley is pressed onto the hub shaft, viscous fan drive removal/installation procedures
are unique.
The fan/viscous fan drive assembly can be removed or installed from the water pump by turning
the mounting nut. To remove the fan/viscous fan drive assembly, turn the nut counterclockwise as
viewed from the front. To install the fan/viscous fan drive assembly, turn the nut clockwise as
viewed from the front. Threads on the viscous fan drive are RIGHT-HANDED. Snap-On 36 mm Fan
Wrench (number SP346 from Snap-On Cummins Diesel Tool Set number 2017DSP) can be used
to remove/install the fan drive assembly on gasoline engines. To hold the water pump pulley from
rotating, place Miller Special Tool 6958 Spanner Wrench onto the water pump pulley with adapter
pins 8346 inserted into the holes on the pulley (Figure 1).
NOTE:

Engine Cooling Fan Noise
MODELS:
1998 - 1999 (AB) Ram Van/Wagon 1997 - 1999 (AN) Dakota 1998 - 1999 (DN) Durango
DISCUSSION:
Some vehicles may exhibit an engine cooling fan "roar" noise. This noise is created by a large
cooling fan that is required to provide optimum cooling for low vehicle speed operation in hot
weather conditions and for heavy trailer towing. Since the large cooling fan is unnecessary in most
operating conditions, these vehicles are also equipped with viscous fan drives that allow the fan to
operate at variable speeds based upon temperature loads. The viscous fan drive will engage the
fan for maximum cooling when temperatures are high and allow the fan to operate at slower
speeds when temperatures are low. In addition, at engine start-up, the viscous fan drive engages
the fan for maximum cooling until the fluid in the viscous clutch can dissipate out of the clutch drive
grooves allowing the fan to operate at a slower speed.
Because of the viscous fan drive, the noise may occur during high temperature conditions and for
the first 1-2 minutes of operation. Due to the roar of the fan, customers may also complain of a
perceived loss of power, automatic transmission slippage, or that the transmission is slaying into a
low gear too long (delayed upshift).
Customers concerned about this noise should be advised that this condition is normal and no
repair attempts should be made.

VISCOUS FAN DRIVE
Fan Blade/Viscous Fan Drive Assembly
Viscous Fan Drive-Typical
The thermal viscous fan drive is a silicone-fluid- filled coupling used to connect the fan blades to
the water pump shaft. The coupling allows the fan to be driven in a normal manner. This is done at
low engine speeds while limiting the top speed of the fan to a predetermined maximum level at
higher engine speeds. A thermostatic bi-metallic spring coil is located on the front face of the
viscous fan drive unit (a typical viscous unit is shown in. This spring coil reacts to the temperature
of the radiator discharge air. It engages the viscous fan drive for higher fan speed if the air
temperature from the radiator rises above a certain point. Until additional engine cooling is
necessary, the fan will remain at a reduced rpm regardless of engine speed. Only when sufficient
heat is present, will the viscous fan drive engage. This is when the air flowing through the radiator
core causes a reaction to the bimetallic coil. It then increases fan speed to provide the necessary
additional engine cooling. Once the engine has cooled, the radiator discharge temperature will
drop. The bimetallic coil again reacts and the fan speed is reduced to the previous disengaged
speed.
CAUTION: Engines equipped with serpentine drive belts have reverse rotating fans and viscous
fan drives. They are marked with the word REVERSE to designate their usage. Installation of the
wrong fan or viscous fan drive can result in engine overheating.
CAUTION: If the viscous fan drive is replaced because of mechanical damage, the cooling fan
blades should also be inspected. Inspect for fatigue cracks, loose blades, or loose rivets that could
have resulted from excessive vibration. Replace fan blade assembly if any of these conditions are
found. Also inspect water pump bearing and shaft assembly for any related damage due to a
viscous fan drive malfunction.
NOISE
NOTE: It is normal for fan noise to be louder (roaring) when:

^ The underhood temperature is above the engagement point for the viscous drive coupling. This
may occur when ambient (outside air temperature) is very high.
^ Engine loads and temperatures are high such as when towing a trailer.
^ Cool silicone fluid within the fan drive unit is being redistributed back to its normal disengaged
(warm) position. This can occur during the first 15 seconds to one minute after engine start-up on a
cold engine.
LEAKS Viscous fan drive operation is not affected by small oil stains near the drive bearing. If
leakage appears excessive, replace the fan drive unit.

VISCOUS FAN DRIVE
TESTING
If the fan assembly free-wheels without drag (the fan blades will revolve more than five turns when
spun by hand), replace the fan drive. This spin test must be performed when the engine is cool. For
the following test, the cooling system must be in good condition. It also will ensure against
excessively high coolant temperature.
WARNING: BE SURE THAT THERE IS ADEQUATE FAN BLADE CLEARANCE BEFORE
DRILLING.
1. Drill a 3.18-mm (1/8-in) diameter hole in the top center of the fan shroud. 2. Obtain a dial
thermometer with an 8 inch stem (or equivalent). It should have a range of -18° to 105°C (0° to
220°F). Insert thermometer through
the hole in the shroud. Be sure that there is adequate clearance from the fan blades.
3. Connect a tachometer and an engine ignition timing light (timing light is to be used as a strobe
light). 4. Block the air flow through the radiator. Secure a sheet of plastic in front of the radiator (or
air conditioner condenser). Use tape at the top to secure
the plastic and be sure that the air flow is blocked.
5. Be sure that the air conditioner (if equipped) is turned off.
WARNING: USE EXTREME CAUTION WHEN THE ENGINE IS OPERATING. DO NOT STAND IN
A DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELTS OR
FAN. DO NOT WEAR LOOSE CLOTHING.
6. Start the engine and operate at 2400 rpm. Within ten minutes the air temperature (indicated on
the dial thermometer) should be up to 88° C (190°
F). Fan drive engagement should have started to occur at between 74° to 82° C (165° to 180° F).
Engagement is distinguishable by a definite increase in fan flow noise (roaring). The timing light
also will indicate an increase in the speed of the fan.
7. When the air temperature reaches 88° C (190° F), remove the plastic sheet. Fan drive
disengagement should have started to occur at between 57°
to 79° C (135° to 175° F). A definite decrease of fan flow noise (roaring) should be noticed. If not,
replace the defective viscous fan drive unit.

Description and Operation
Heater Core: Description and Operation
SYSTEM OPERATION
Front
The heater core is located in the heater-A/C housing, on the right side of the engine compartment.
It is a heat exchanger made of rows of tubes and fins. Engine coolant is circulated through heater
hoses to the heater core whenever the front water valve is open. As the coolant flows through the
heater core, heat removed from the engine is transferred to the heater core fins and tubes.
Air directed through the heater core picks up the heat from the heater core fins. The blend air door
allows control of the heater output air temperature by controlling how much of the air flowing
through the heater-A/C housing is directed through or around the heater core. The blower motor
speed controls the volume of air flowing through the heater-A/C system.
The heater core cannot be repaired and, if faulty or damaged, it must be replaced.
Rear
Models equipped with the optional rear heater-A/C unit have a combination coil located within the
rear unit housing. The combination coil functions as both the rear heater core and the rear
evaporator coil. See Combination Coil in the Description and Operation for more information.

Temperature Gauge > Component Information > Description and Operation
Temperature Gauge: Description and Operation
SYSTEM OPERATION
The coolant temperature gauge gives an indication of the engine coolant temperature. The
instrument cluster circuitry controls the gauge pointer position. The instrument cluster circuitry
calculates the proper gauge pointer position based upon engine coolant temperature messages
received from the Powertrain Control Module (PCM) on the Chrysler Collision Detection (CCD)
data bus.
The PCM uses an input from the engine coolant temperature sensor and internal programming to
decide what engine coolant temperature messages are required. The PCM then sends the proper
messages to the instrument cluster on the CCD data bus.
If the PCM messages indicate that coolant temperature is too high, the instrument cluster circuitry
moves the gauge needle to the high end of the scale on the gauge face, turns on the Check
Gauges lamp, and sends a chime tone request to the Central Timer Module (CTM).
The engine coolant temperature sensor is installed in a threaded hole that penetrates a coolant
passage of the engine. It is a thermistor-type sensor that changes its internal resistance with
changes in engine coolant temperature.

Temperature Gauge: Testing and Inspection
If the problem being diagnosed is related to coolant temperature gauge accuracy, be certain to
confirm that the problem is with the gauge and not with cooling system performance. The actual
engine coolant temperature should be checked with a test gauge or thermometer and compared to
the instrument cluster coolant temperature gauge readings before you proceed with gauge
diagnosis.

COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
Diagnosis of the coolant temperature sensor and circuit, the Chrysler Collision Detection (CCD)
data bus, and/or the Powertrain Control Module (PCM) should be performed with a DRB scan tool.

messages received from the PCM on the Chrysler Collision Detection (CCD) data bus. The PCM
sends lamp-on messages for about two seconds when the ignition switch is turned to the On
position as a bulb test.
Following the bulb test, the PCM uses an input from the automatic transmission oil temperature
sensor located within the transmission, along with its internal programming, to decide whether a
condition exists that requires the transmission oil temperature warning lamp to be turned on. The
PCM then sends the proper messages to the instrument cluster on the CCD data bus to turn the
lamp on or off. When the instrument cluster receives a message to turn the transmission oil
temperature warning lamp on, it also sends a chime tone request to the Central Timer Module
(CTM).

Description and Operation
Radiator Cap: Description and Operation
Radiator Pressure Cap And Filler Neck-Typical
Radiators are equipped with a pressure cap, which releases pressure at some point within a range
of 97-138 kPa (14-20 psi). The pressure relief point (in pounds) is engraved on top of cap. The
cooling system will operate at pressures slightly above atmospheric pressure. This results in a
higher coolant boiling point allowing increased radiator cooling capacity. The cap contains a
spring-loaded pressure relief valve that opens when system pressure reaches release range of
97-138 kPa (14-20 psi). A vent valve in the center of cap allows a small coolant flow through cap
when coolant is below boiling temperature. The valve is completely closed when boiling point is
reached. As the coolant cools, it contracts and creates a vacuum in the cooling system. This
causes the vacuum valve to open and coolant in the reserve/overflow tank to be drawn through its
connecting hose into radiator. If the vacuum valve is stuck shut, the radiator hoses will collapse on
cool down. Clean the vent valve. A rubber gasket seals radiator filler neck to prevent leakage. This
is done to keep system under pressure. It also maintains vacuum during coolant cool-down
allowing coolant to return from reserve/ overflow tank.

PRESSURE TESTING
Pressure Testing Radiator Cap
Remove cap from radiator. Be sure that sealing surfaces are clean. Moisten rubber gasket with
water and install cap on pressure tester 7700 or an equivalent. Operate tester pump to bring
pressure to 104 kPa (15 psi) on gauge. If pressure cap fails to hold pressure of at least 97 kPa (14
psi) replace cap. The pressure cap may test properly while positioned on tool 7700 (or equivalent).
It may not hold pressure or vacuum when installed on radiator. If so, inspect radiator filler neck and
cap's top gasket for damage. Also inspect for dirt or distortion that may prevent cap from sealing
properly.
CAUTION: Radiator pressure testing tools are very sensitive to small air leaks, which will not cause
cooling system problems. A pressure cap that does not have a history of coolant loss should not be
replaced just because it leaks slowly when tested with this tool. Add water to tool. Turn tool upside
down and recheck pressure cap to confirm that cap needs replacement.

INSPECTION
Hold cap at eye level, right side up. The vent valve at bottom of cap should open. If rubber gasket
has swollen and prevents vent valve from opening, replace cap. Hold cap at eye level, upside
down. If any light can be seen between vent valve and rubber gasket, replace cap. Do not use a
replacement cap that has a spring to hold vent shut. A replacement cap must be the type designed
for a coolant reserve/overflow system with a completely sealed diaphragm spring and a rubber
gasket. This gasket is used to seal to radiator filler neck top surface. Use of proper cap will allow
coolant return to radiator.

Information > Description and Operation
Temperature Gauge: Description and Operation
SYSTEM OPERATION
The coolant temperature gauge gives an indication of the engine coolant temperature. The
instrument cluster circuitry controls the gauge pointer position. The instrument cluster circuitry
calculates the proper gauge pointer position based upon engine coolant temperature messages
received from the Powertrain Control Module (PCM) on the Chrysler Collision Detection (CCD)
data bus.
The PCM uses an input from the engine coolant temperature sensor and internal programming to
decide what engine coolant temperature messages are required. The PCM then sends the proper
messages to the instrument cluster on the CCD data bus.
If the PCM messages indicate that coolant temperature is too high, the instrument cluster circuitry
moves the gauge needle to the high end of the scale on the gauge face, turns on the Check
Gauges lamp, and sends a chime tone request to the Central Timer Module (CTM).
The engine coolant temperature sensor is installed in a threaded hole that penetrates a coolant
passage of the engine. It is a thermistor-type sensor that changes its internal resistance with
changes in engine coolant temperature.

Temperature Gauge: Testing and Inspection
If the problem being diagnosed is related to coolant temperature gauge accuracy, be certain to
confirm that the problem is with the gauge and not with cooling system performance. The actual
engine coolant temperature should be checked with a test gauge or thermometer and compared to
the instrument cluster coolant temperature gauge readings before you proceed with gauge
diagnosis.

Thermostat: Description and Operation
Thermostats installed in the 3.9L/5.2L/5.9L engines are of the wax- pellet-driven,
reverse-poppet-choke-type. The wax pellet is located in a sealed container at spring end of
thermostat. When heated, the pellet expands, overcoming closing spring tension and water pump
pressure to force valve to open. Coolant leakage into pellet container will cause thermostat to fail in
open position. Do not attempt to free a sticking thermostat with a prying device. The thermostat
controls the operating temperature of the engine by controlling the amount of coolant flow to
radiator. On all engines, the thermostat is closed below 88°C (192°F). When coolant reaches this
temperature, thermostat begins to open allowing coolant flow to radiator. This provides quick
engine warm-up and overall temperature control. The thermostat is designed to provide a minimum
engine operating temperature range of from 88 to 93°C (192 to 199°F). The thermostat should be
fully open for maximum coolant flow during operation in hot ambient temperatures of approximately
104°C (220°F). Above 104°C (220°F), coolant temperature is controlled by radiator, fan and
ambient temperature. An arrow, plus the word UP is stamped on front flange next to air bleed. The
words TO RAD are stamped on one arm of thermostat. They indicate proper installed position. The
same thermostat is used for winter and summer seasons.
CAUTION: Do not operate an engine without a thermostat, except for servicing or testing.
An engine should not be operated without a thermostat, except for servicing or testing. Operating
without a thermostat causes longer engine warm-up time, unreliable warm-up performance,
increased exhaust emissions and crankcase condensation that can result in sludge formation.

Water Pump: Description and Operation
A centrifugal water pump circulates coolant through the water jackets, passages, intake manifold,
radiator core, cooling system hoses and heater core. The pump is driven from the engine
crankshaft by a drive belt.
The water pump impeller is pressed onto the rear of a shaft that rotates in a bearing pressed into
the water pump body. The body has a small hole for ventilation. The water pump seals are
lubricated by antifreeze in the coolant mixture. Additional lubrication is not necessary.
A quick test to determine if pump is working is to check if heater warms properly. A defective water
pump will not be able to circulate heated coolant through the long heater hose to the heater core.
The water pump on all models can be removed without discharging the air conditioning system (if
equipped).

Catalytic Converter: Customer Safety Information
CATALYTIC CONVERTER
The catalytic converter routinely reaches operating temperatures of 650° C (1200° F) and will stay
hot for some time after the engine has been shut off. Do NOT park the vehicle over any object or
material that could ignite (i.e. dry leaves, cardboard, puddles of oil, or other combustibles).
CARBON MONOXIDE
Exhaust gas contains toxic carbon monoxide. Do not run the engine in confined areas or breathe
concentrated exhaust gases. Breathing exhaust gases may cause loss of consciousness or death.
EXHAUST SYSTEM LEAKS
Repair any leaks in the exhaust system as soon as possible. Hot gases escaping from the leak can
ignite flammable materials and may set the vehicle on fire.
Also exhaust may circulate through the passenger compartment causing throat, sinus, and eye
irritation, light headedness, headaches, and increased irritability, especially while driving with
windows closed.
FUEL ODORS/EXCESSIVE EMISSIONS
Be alert for fuel odors and excessive tailpipe emissions (black smoke etc...). These indicate a
problem that should be corrected as soon as possible (excessive emissions can ruin oxygen
sensors, catalytic converters, and other expensive emission components).

Heat Shield: Description and Operation
Exhaust heat shields are needed to protect both the vehicle and the environment from the high
temperatures developed by the catalytic converter. The
combustion reaction facilitated by the catalyst releases additional heat in the exhaust system.
Under severe operating conditions, the temperature increases in the area of the reactor. Such
conditions can exist when the engine misfires or otherwise does not operate at peak efficiency. DO
NOT remove spark plug wires from plugs or by any other means short out cylinders. Failure of the
catalytic converter can occur due to a temperature increase caused by unburned fuel passing
through the converter. Do not allow the engine to operate at fast idle for extended periods (over 5
minutes). This condition may result in excessive temperatures in the exhaust system and on the
floor pan.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.

Body Control Module: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation
Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of
the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check
voltage. Refer to the
appropriate test procedure.

Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and
Modules - Computers and Control Systems > Body Control Module > Component Information > Diagrams > Diagram
Information and Instructions > Page 1747
Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Body Control Module: Description and Operation System Description and Functional Operation
The body system on the 1998 AB HIGH LINE consists of three modules that communicate over the
CCD bus (Chrysler Collision Detection multiplex system). There are two additional modules, the
Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the
body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for
diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are
performed through the Serial Communication Interface of SCI, the same as previous years. All of
the information about the functioning of all the system is organized, controlled, and communicated
by the CCD bus, which is described in Section 3 (CCD Bus) of this general information section.
Through the CCD bus, information about the operation of vehicle components and circuits is
relayed quickly to the appropriate module(s). All modules receive all the information transmitted on
the bus even though a module may not require all the information to perform it's function. It will only
respond to messages "addressed" to it through a binary coding process. This method of data
transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring
harnesses.

Owner Letter
EMISSIONS RECALL TO REPROGRAM YOUR VEHICLE'S POWERTRAIN CONTROL MODULE
Dear DaimlerChrysler Vehicle Owner:
DaimlerChrysler has determined that some 1998 Dodge Dakota, Durango, Ram Van/Wagon, Ram
Truck, and Jeep(R) Grand Cherokee vehicles, equipped with a V-8 or V-10 engine, may be in
violation of California Emissions Regulations.
The problem is...
The On-Board Diagnostic (OBD) system on your vehicle (identified on the enclosed form) may not
detect evaporative emissions purge system malfunctions as required by California Emissions
Regulations. As a result, the OBD system on your vehicle may not illuminate the "Check Engine"
light if the evaporative emissions purge system malfunctions. This could cause your vehicle to emit
hydrocarbon levels above the limits that were established to protect the public health from the
dangers of air pollution.
Hydrocarbons (unburned fuel) combined with oxides of nitrogen, in the presence of sunlight, can
cause the formation of ozone. These pollutants are the primary components of smog.
What DaimlerChrysler and your dealer will do...
DaimlerChrysler will repair your vehicle free of charge (parts and labor). To do this, your dealer will
reprogram your vehicle's powertrain control module. The work will take about 1/2 hour to complete.
However, additional time may be necessary depending on how dealer appointments are scheduled
and processed.
What you must do...
^ Simply contact your dealer right away to schedule a service appointment.
^ Bring the enclosed Owner Notification form with you to your dealer. It identifies the required
service to the dealer.
If you live in California and don't get this done...
The State of California requires the completion of emission recall repairs prior to vehicle
registration renewal. In addition, the State requires that every vehicle must pass an emission test
(SMOG Check) every two years and before it is sold. Without the free service we are providing,
your vehicle may be more likely to fail this test and require that you make costly repairs.
How the state knows that the recall has been performed...
State of California regulations require DaimlerChrysler to provide the Department of Motor Vehicles
with a record of all vehicles that have not had the recall service performed. If you live in the state of
California and your vehicle is not on this list, the state will know that the recall has been completed.
Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the
recall service is completed. Be sure to save this form since the California Department of Motor
Vehicles may require that you supply it as proof of recall completion.
If you need help...
If you have trouble getting your vehicle repaired, please call the DaimlerChrysler Customer
Assistance Center, toll free, at 1-800-992-1997. A representative will assist you in getting your
vehicle repaired.
In order to ensure your full protection under the emission warranty provisions, it is recommended
that you have your vehicle serviced as soon as possible. Failure to do so could be determined as
lack of proper maintenance of your vehicle.
We are sorry for any inconvenience but trust you understand our interest in clean air and your
continued satisfaction with our products. Thank you for your attention to this important matter.

Owner Letter
EMISSIONS RECALL TO REPROGRAM YOUR VEHICLE'S POWERTRAIN CONTROL MODULE
Dear DaimlerChrysler Vehicle Owner:
DaimlerChrysler has determined that some 1998 Dodge Dakota, Durango, Ram Van/Wagon, Ram
Truck, and Jeep(R) Grand Cherokee vehicles, equipped with a V-8 or V-10 engine, may be in
violation of California Emissions Regulations.
The problem is...
The On-Board Diagnostic (OBD) system on your vehicle (identified on the enclosed form) may not
detect evaporative emissions purge system malfunctions as required by California Emissions
Regulations. As a result, the OBD system on your vehicle may not illuminate the "Check Engine"
light if the evaporative emissions purge system malfunctions. This could cause your vehicle to emit
hydrocarbon levels above the limits that were established to protect the public health from the
dangers of air pollution.
Hydrocarbons (unburned fuel) combined with oxides of nitrogen, in the presence of sunlight, can
cause the formation of ozone. These pollutants are the primary components of smog.
What DaimlerChrysler and your dealer will do...
DaimlerChrysler will repair your vehicle free of charge (parts and labor). To do this, your dealer will
reprogram your vehicle's powertrain control module. The work will take about 1/2 hour to complete.
However, additional time may be necessary depending on how dealer appointments are scheduled
and processed.
What you must do...
^ Simply contact your dealer right away to schedule a service appointment.
^ Bring the enclosed Owner Notification form with you to your dealer. It identifies the required
service to the dealer.
If you live in California and don't get this done...
The State of California requires the completion of emission recall repairs prior to vehicle
registration renewal. In addition, the State requires that every vehicle must pass an emission test
(SMOG Check) every two years and before it is sold. Without the free service we are providing,
your vehicle may be more likely to fail this test and require that you make costly repairs.
How the state knows that the recall has been performed...
State of California regulations require DaimlerChrysler to provide the Department of Motor Vehicles
with a record of all vehicles that have not had the recall service performed. If you live in the state of
California and your vehicle is not on this list, the state will know that the recall has been completed.
Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the
recall service is completed. Be sure to save this form since the California Department of Motor
Vehicles may require that you supply it as proof of recall completion.
If you need help...
If you have trouble getting your vehicle repaired, please call the DaimlerChrysler Customer
Assistance Center, toll free, at 1-800-992-1997. A representative will assist you in getting your
vehicle repaired.
In order to ensure your full protection under the emission warranty provisions, it is recommended
that you have your vehicle serviced as soon as possible. Failure to do so could be determined as
lack of proper maintenance of your vehicle.
We are sorry for any inconvenience but trust you understand our interest in clean air and your
continued satisfaction with our products. Thank you for your attention to this important matter.

DISCUSSION:
Whenever any connector on the PCM is disconnected, the ignition switch must be in the "OFF"
position for a minimum of 5 seconds before connector removal.
It has been found under certain key "ON" or momentary key "OFF" conditions, when the black
connector is unplugged, the PCM may attempt to write information to the EEPROM processor
within the PCM. Sometimes this inadvertent write will set the target charging voltage to 0 (zero)
volts. The result will prevent the charging system from charging the battery.
If this occurs, the only correction is PCM replacement.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Information and Instructions > Page 1806
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers.
- Connectors located on the instrument panel harness are C200 series numbers.
- Connectors located on the body harness are C300 series numbers.

Dodge 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 1808
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Dodge 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 1809
Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.
- ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE
CLOTHING.
Positive Temperature Coefficient
Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's
act like a solid state fuse. They are located in the

junction block, and are used to protect such items as: power door lock motors, power windows, and
various engine solenoids.
Positive Temperature Coefficient Symbol
A special symbol is used to identify these in the wiring diagrams.
Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Engine Control Module: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation
Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of
the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check
voltage. Refer to the
appropriate test procedure.

Modules - Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram
Information and Instructions > Page 1821
Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Engine Control Module: Description and Operation
SYSTEM OPERATION
Powertrain Control Module (PCM)
The Powertrain Control Module (PCM) is located in the engine compartment. The ignition system is
controlled by the PCM.
NOTE: Base ignition timing by rotation of distributor is not adjustable.
The PCM opens and closes the ignition coil ground circuit to operate the ignition coil. This is done
to adjust ignition timing, both initial (base) and advance, and for changing engine operating
conditions. The amount of electronic spark advance provided by the PCM is determined by five
input factors: engine coolant temperature, engine rpm, intake manifold temperature, manifold
absolute pressure and throttle position.

Camshaft Position Sensor: Description and Operation
SYSTEM OPERATION
The camshaft position sensor is located in the distributor on all engines.
The sensor contains a hall effect device called a sync signal generator to generate a fuel sync
signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The
pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction
with the crankshaft position sensor to differentiate between fuel injection and spark events. It is
also used to synchronize the fuel injectors with their respective cylinders.
When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following
occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync
signal of approximately 5 volts.
When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following
occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts.

Camshaft Position Sensor: Testing and Inspection
Camshaft Position Sensor - Typical
The camshaft position sensor is located in the distributor on all engines.
To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain
Diagnostics Procedures service. To test the sensor only, refer to the following:
For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector
from the distributor. Using small paper clips, insert them into the backside of the distributor wire
harness connector to make contact with the terminals. Be sure that the connector is not damaged
when inserting the paper clips. Attach voltmeter leads to these paper clips.
1. Remove engine cover. 2. Connect the positive (+) voltmeter lead into the sensor output wire.
This is at done the distributor wire harness connector. For wire identification. 3. Connect the
negative (-) voltmeter lead into the ground wire. For wire identification. 4. Set the voltmeter to the
15 Volt DC scale. 5. Remove distributor cap from distributor (two screws). Rotate (crank) the
engine until the distributor rotor is pointed towards the rear of vehicle.
The movable pulse ring should now be within the sensor pickup.
6. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 7. If voltage is
not present, check the voltmeter leads for a good connection. 8. If voltage is still not present, check
for voltage at the supply wire. For wire identification. 9. If 5 volts is not present at supply wire,
check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for
this
test.
10. If voltage is still not present, perform vehicle test using the DRB scan tool. 11. If voltage is
present at cavity A-17, but not at the supply wire:
a. Check continuity between the supply wire. This is checked between the distributor connector and
cavity A-17 at the PCM. If continuity is not
present, repair the harness as necessary
b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the
PCM. If continuity is not present, repair the
harness as necessary
c. Check for continuity between the ground circuit wire at the distributor connector and ground. If
continuity is not present, repair the harness as
necessary.
12. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle
should fluctuate between 0 and 5 volts while the
engine is cranking. This verifies that the camshaft position sensor in the distributor is operating
properly and a sync pulse signal is being generated. If sync pulse signal is not present,
replacement of the camshaft position sensor is necessary.

Crankshaft Position Sensor: Description and Operation
SYSTEM OPERATION
Sensor Operation
Engine speed and crankshaft position are provided through the crankshaft position sensor. The
sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM
interprets the sensor input to determine the crankshaft position. The PCM then uses this position,
along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
On this engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its
outer edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM. For each engine revolution, there are 8 pulses generated on V-8 engines.
The engine will not operate if the PCM does not receive a crankshaft position sensor input.

Throttle Position Sensor: Testing and Inspection
The Throttle Position Sensor (TPS) can be tested with a digital voltmeter. The center terminal of
the TPS is the output terminal.
With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of
the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT).
- At idle, TPS output voltage should should be greater than 0.350 millivolts and less than 900
millivolts.
- At wide open throttle, TPS output voltage must be less than 4.5 volts.
- The output voltage should increase gradually as the throttle plate is slowly opened from idle to
WOT.
NOTE: For additional testing information and circuit diagnosis see Computers and Control
Systems/System Diagnosis/Procedures/Diagnostic Charts.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers.
- Connectors located on the instrument panel harness are C200 series numbers.
- Connectors located on the body harness are C300 series numbers.

Information and Instructions > Page 1955
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Information and Instructions > Page 1956
Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.
- ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE
CLOTHING.
Positive Temperature Coefficient

junction block, and are used to protect such items as: power door lock motors, power windows, and
various engine solenoids.
Positive Temperature Coefficient Symbol
A special symbol is used to identify these in the wiring diagrams.
Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

International symbols are used throughout the wiring diagrams. These symbols are consistent with
those being used around the world.
Take-Outs
The abbreviation T/O is used in the Component Location group to indicate a point at which the
wiring harness branches out to a component.
How to Find System & Component Diagrams
When trying to find the diagram for a specific component or system, use the Group Index
information or the Alphabetic Index to Wiring Diagrams under Electrical
Whenever a reference exists to another sheet or figure, find the corresponding diagram using the
Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number

Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Throttle Position Sensor: Testing and Inspection
The Throttle Position Sensor (TPS) can be tested with a digital voltmeter. The center terminal of
the TPS is the output terminal.
With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of
the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT).
- At idle, TPS output voltage should should be greater than 0.350 millivolts and less than 900
millivolts.
- At wide open throttle, TPS output voltage must be less than 4.5 volts.
- The output voltage should increase gradually as the throttle plate is slowly opened from idle to
WOT.
NOTE: For additional testing information and circuit diagnosis see Computers and Control
Systems/System Diagnosis/Procedures/Diagnostic Charts.

Camshaft Position Sensor: Description and Operation
SYSTEM OPERATION
The camshaft position sensor is located in the distributor on all engines.
The sensor contains a hall effect device called a sync signal generator to generate a fuel sync
signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The
pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction
with the crankshaft position sensor to differentiate between fuel injection and spark events. It is
also used to synchronize the fuel injectors with their respective cylinders.
When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following
occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync
signal of approximately 5 volts.
When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following
occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts.

Camshaft Position Sensor: Testing and Inspection
Camshaft Position Sensor - Typical
The camshaft position sensor is located in the distributor on all engines.
To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain
Diagnostics Procedures service. To test the sensor only, refer to the following:
For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector
from the distributor. Using small paper clips, insert them into the backside of the distributor wire
harness connector to make contact with the terminals. Be sure that the connector is not damaged
when inserting the paper clips. Attach voltmeter leads to these paper clips.
1. Remove engine cover. 2. Connect the positive (+) voltmeter lead into the sensor output wire.
This is at done the distributor wire harness connector. For wire identification. 3. Connect the
negative (-) voltmeter lead into the ground wire. For wire identification. 4. Set the voltmeter to the
15 Volt DC scale. 5. Remove distributor cap from distributor (two screws). Rotate (crank) the
engine until the distributor rotor is pointed towards the rear of vehicle.
The movable pulse ring should now be within the sensor pickup.
6. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 7. If voltage is
not present, check the voltmeter leads for a good connection. 8. If voltage is still not present, check
for voltage at the supply wire. For wire identification. 9. If 5 volts is not present at supply wire,
check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for
this
test.
10. If voltage is still not present, perform vehicle test using the DRB scan tool. 11. If voltage is
present at cavity A-17, but not at the supply wire:
a. Check continuity between the supply wire. This is checked between the distributor connector and
cavity A-17 at the PCM. If continuity is not
present, repair the harness as necessary
b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the
PCM. If continuity is not present, repair the
harness as necessary
c. Check for continuity between the ground circuit wire at the distributor connector and ground. If
continuity is not present, repair the harness as
necessary.
12. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle
should fluctuate between 0 and 5 volts while the
engine is cranking. This verifies that the camshaft position sensor in the distributor is operating
properly and a sync pulse signal is being generated. If sync pulse signal is not present,
replacement of the camshaft position sensor is necessary.

Crankshaft Position Sensor: Description and Operation
SYSTEM OPERATION
Sensor Operation
Engine speed and crankshaft position are provided through the crankshaft position sensor. The
sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM
interprets the sensor input to determine the crankshaft position. The PCM then uses this position,
along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
On this engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its
outer edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM. For each engine revolution, there are 8 pulses generated on V-8 engines.
The engine will not operate if the PCM does not receive a crankshaft position sensor input.

Fuel Pressure: Capacity Specifications
NOTE: Before performing this test, verify fuel pump pressure by performing the Fuel Pump
Pressure Test. Use this test in conjunction with the Fuel Pressure Leak Down Test.
1. Release fuel system pressure.
- Refer to the Fuel Pressure Release Procedure.
2. Disconnect the fuel supply line at fuel rail.
- Some engines may require air cleaner housing removal before line disconnection.
3. Connect appropriate Fuel Line Pressure Test Adapter Tool Hose (number 6631, 6923, 6541 or
6539) into disconnected fuel supply line.
- Insert other end of Adaptor Tool hose into a graduated container.
4. Remove the fuel fill cap. 5. To activate fuel pump and pressurize system, obtain DRB scan tool
and actuate ASD Fuel System Test. 6. A good fuel pump will deliver at least 1/4 liter of fuel in 7
seconds.
- Do not operate fuel pump for longer than 7 seconds with fuel line disconnected as fuel pump
module reservoir may run empty.
a. If capacity is lower than specification, but fuel pump can be heard operating through fuel fill cap
opening, check for a kinked/damaged fuel
supply line somewhere between fuel rail and fuel pump module.
b. If line is not kinked/damaged, and fuel pressure is OK, but capacity is low, replace fuel filter/ fuel
pressure regulator. The filter/regulator may be serviced separately on certain applications.

Fuel Pressure: Testing and Inspection Fuel Pressure Leak Down Test
Fig 9 Connecting Adaptor Tool -- Typical
Fig. 8 Installing Adapter Tool And Pressure Gauge
NOTE: Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity
Test.
Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational.
After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid
gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure
that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the
electric fuel pump is activated, fuel pressure should immediately rise to specification.
Abnormally long periods of cranking to restart a hot engine that has been shut down for a short
period of time may be caused by: Fuel pressure bleeding past a fuel injector(s).
- Fuel pressure bleeding past the check valve in the fuel pump module.
1. Disconnect the fuel inlet line at fuel rail.
- On some engines, air cleaner housing removal may be necessary before fuel line disconnection.
2. Connect the appropriate Fuel Line Pressure Test Adapter Tool (number 6539, 6631, 6541 or
6923) between the disconnected fuel line and fuel rail
(Fig. 9) or (Fig. 10).
3. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test
port on the appropriate Adaptor Tool.
- The fittings on both tools must be in good condition and free from any small leaks before
performing the proceeding test.
4. Start engine and bring to normal operating temperature.

Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Fuel Pressure >
System Information > System Diagnosis > Fuel Pressure Leak Down Test > Page 2027
5. Observe test gauge. Normal operating pressure should be 339 kPa +/- 34 kPa (49.2 psi +/- 5
psi). 6. Shut engine off. 7. Pressure should not fall below 30 psi for five minutes. 8. If pressure falls
below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module,
or a fuel tube/line is leaking. 9. Again, start engine and bring to normal operating temperature.
10. Shut engine off. 11. Testing for fuel injector or fuel rail leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on
Adapter Tool.
- If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking.
12. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T"
on Adapter Tool.
- If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line.
- If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump
or filter/ regulator may be leaking.
NOTE: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A
slow loss of pressure usually indicates a defective check valve in the electric fuel pump.
The electric fuel pump is not serviced separately -- Replace the fuel pump module assembly. The
filter/ regulator may be replaced separately on certain applications. Refer to Fuel Filter/Fuel
Pressure Regulator Removal/installation for additional information.

Fuel Pressure: Testing and Inspection Fuel Pressure Test
Fuel Pressure Test Gauge
NOTE: Use this test in conjunction with the Fuel Pump Capacity Test, Fuel Pressure Leak Down
Test, fuel pump amperage test.
Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow hack into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational. After the vehicle has cooled down fuel pressure may drop to 0 psi (cold fluid
contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel
injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal
condition. When the electric fuel pump is activated, fuel pressure should immediately rise to
specification.
All fuel systems are equipped with a fuel tank module mounted, combination fuel filter/fuel pressure
regulator. The fuel pressure regulator is not controlled by engine vacuum.
WARNING: The fuel system is under constant fuel pressure even with the engine off. Before
disconnecting fuel line at fuel rail, this pressure must be released. Refer to the fuel system
pressure release procedure.
NOTE: To perform this test you will need to remove the engine cover.
1. Remove the protective cap at the fuel rail test port. Connect the 0-414 kPa (0-60 psi) fuel
pressure gauge (from gauge set 5069) to the test port
pressure fitting on the fuel rail.
2. Start and warm the engine and note pressure gauge reading. Fuel pressure should be 3.39 kPa
+/- 34 kPa (49.2 psi +/- 5 psi) at idle. 3. If engine runs but pressure is below 44.2 psi, check for a
kinked fuel supply line somewhere between fuel rail and fuel pump module. If line is not
kinked, replace fuel pump module assembly. Refer to Fuel Pump Removal/Installation.
4. If operating pressure is above 54.2 psi, electric fuel pump is OK, but fuel pressure regulator is
defective. Replace fuel filter/fuel pressure regulator.
Certain filter/regulators may be serviced separately and some require the replacement of the fuel
pump module assembly Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for more
information.

Ignition Cable: Description and Operation
SYSTEM OPERATION
Spark plug cables are sometimes referred to as secondary ignition wires. These cables transfer
electrical current from the ignition coil(8) and/or distributor, to individual spark plugs at each
cylinder. The resistive spark plug cables are of nonmetallic construction. The cables provide
suppression of radio frequency emissions from the ignition system.

Component Information > Technical Service Bulletins > Page 2091
Ignition Cable: Testing and Inspection
Heat Shields
Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and
spark plugs. Terminals should be fully seated. The insulators should be in good condition and
should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are
cracked or torn must be replaced.
Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the
cables dry. Check for brittle or cracked insulation.
Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable
boot and spark plug . These shields protect the spark plug boots from damage (due to intense
engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug
cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat
shield.
Testing
When testing secondary cables for damage with an oscilloscope, follow the instructions of the
equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as
follows:
CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during
testing. This may cause possible heat damage to the catalytic converter. Total test time must not
exceed ten minutes.
With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to
a good engine ground. If the cable and spark plug are in good condition, the engine rpm should
drop and the engine will run poorly If engine rpm does not drop, the cable and/or spark plug may
not be operating properly and should be replaced. Also check engine cylinder compression.
With the engine not running, connect one end of a test probe to a good ground. Start the engine
and run the other end of the test probe along the entire length of all spark plug cables. If cables are
cracked or punctured, there will be a noticeable spark jump from the damaged area to the test
probe. The cable running from the ignition coil to the distributor cap can be checked in the same
manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This
can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket.
Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped,
remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from
spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode
in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable
from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not
within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable.
Test all spark plug cables in this manner.
Spark Plug Cable Resistance MINIMUM = MAXIMUM 250 Ohms Per Inch = 1000 Ohms Per Inch
3000 Ohms Per Foot = 12,000 Ohms Per Foot
To test ignition coil-to-distributor cap cab]e, do not remove the cable from the cap. Connect
ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of
cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart,
remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable.
If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace
the cable. Inspect the ignition coil tower for cracks, burns or corrosion.

Ignition Cable: Service and Repair
REMOVAL AND INSTALLATION
Cable Removal
CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap,
twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off
with a steady, even force.
Engine Firing Order
Install cables into the proper engine cylinder firing order.
When replacing the spark plug and coil cables, route the cables correctly and secure in the proper
retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It
could also cause cross ignition of the plugs or short circuit the cables to ground.
When installing new cables, make sure a positive connection is made. A snap should be felt when
a good connection is made between the plug cable and the distributor cap tower.

Cap Inspection-External-Typical
Cap Inspection-Internal-Typical
Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for
cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the
inside (caused by condensation entering the cap through cracks). Replace any cap that displays
charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will
indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence
of mechanical interference with the rotor tip.

Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip.
Also check for evidence of mechanical interference with the cap. Some charring is normal on the
end of the metal tip. The silicone-dielectric-varnish-compound applied to the rotor tip for radio
interference noise suppression, will appear charred. This is normal. Do not remove the charred
compound. Test the spring for insufficient tension. Replace a rotor that displays any of these
adverse conditions.

Spark Plug: Description and Operation
SYSTEM OPERATION
All engines use resistor type spark plugs. Remove the spark plugs and examine them for burned
electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in
which they were removed from the engine. A single plug displaying an abnormal condition indicates
that a problem exists in the corresponding cylinder.
Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or
oil fouled.

Spark Plug: Testing and Inspection
Normal Operating
Spark Plug Cable Resistance
The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is
evident with most grades of commercial gasoline. There will not be evidence of electrode burning.
Gap growth will not average more than approximately 0.025 mm (0.001 in) per 1600 km (1000
miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the
electrodes filed, have the gap set and then be installed.
Some fuel refiners in several areas of the United States have introduced a manganese additive
(MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug
to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by
coolant in the combustion chamber. Spark plug performance is not affected by MMT deposits.
Cold Fouling/Carbon Fouling
Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are
basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking
valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be
caused by a clogged air cleaner element or repeated short operating times (short trips).
Wet Fouling Or Gas Fouling
A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings,
leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently
overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This
condition can usually be resolved by cleaning and reinstalling the fouled plugs.
Oil Or Ash Encrusted
Oil Or Ash Encrusted
If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of
oil entry into that particular combustion chamber.
Electrode Gap Bridging

Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug >
Component Information > Specifications > Page 2106
Electrode Gap Bridging
Electrode gap bridging may be traced to loose deposits in the combustion chamber. These
deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is
suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between
electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be
cleaned using standard procedures.
Scavenger Deposits
Scavenger Deposit
Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is
a normal condition caused by chemical additives in certain fuels. These additives are designed to
change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that
accumulation on the ground electrode and shell area may be heavy, but the deposits are easily
removed. Spark plugs with scavenger deposits can be considered normal in condition and can be
cleaned using standard procedures.
Chipped Electrode Insulator
Chipped Electrode Insulator
A chipped electrode insulator usually results from bending the center electrode while adjusting the
spark plug electrode gap. Under certain conditions, severe detonation can also separate the
insulator from the center electrode. Spark plugs with this condition must be replaced.
Preignition Damage

Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug >
Component Information > Specifications > Page 2107
Preignition Damage
Preignition damage is usually caused by excessive combustion chamber temperature. The center
electrode dissolves first and the ground electrode dissolves somewhat latter. Insulators appear
relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine.
Determine if ignition timing is over advanced or if other operating conditions are causing engine
overheating. (The heat range rating refers to the operating temperature of a particular type spark
plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon
the thickness and length of the center electrodes porcelain insulator.)
Spark Plug Overheating
Spark Plug Overheating
Overheating is indicated by a white or gray center electrode insulator that also appears blistered.
The increase in electrode gap will be considerably in excess of 0.001 inch per 1000 miles of
operation. This suggests that a plug with a cooler heat range rating should be used. Over
advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug
overheating.

Spark Plug: Service and Repair
Heat Shields
Spark plug cable heat shields are pressed into the cylinder head to surround each cable boot and
spark plug.
If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides
of shield for removal. Each shield is slotted to allow for compression and removal. To install the
shields, align shield to machined opening in cylinder head and tap into place with a block of wood.
PLUG REMOVAL 1. Remove engine cover. 2. Always remove spark plug or ignition coil cables by
grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady
motion. Never pull directly on the cable. Internal damage to cable will result,
3. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area
around the spark plug. This will help prevent
foreign material from entering the combustion chamber.
4. Remove the spark plug using a quality socket with a rubber or foam insert. 5. Inspect the spark
plug condition.
Plug Cleaning The plugs may be cleaned using commercially available spark plug cleaning
equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before
adjusting gap.
CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will
remain on the spark plug insulator arid will cause plug misfire.
Plug Gap Adjustment Check the spark plug gap with a gap gauge tool. If the gap is not correct,
adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center
electrode.
Spark Plug Gap V-8 Engines: 1.01 mm (.040 in).
PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder
head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be
damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in
a change in the spark plug gap or a cracked porcelain insulator.
when replacing the spark plug and ignition coil cables, route the cables correctly and secure them
in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce
ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground.
1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark
plugs to 35-41 N.m (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE

Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Body Control Module: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Body Control Module: Description and Operation System Description and Functional Operation
The body system on the 1998 AB HIGH LINE consists of three modules that communicate over the
CCD bus (Chrysler Collision Detection multiplex system). There are two additional modules, the
Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the
body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for
diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are
performed through the Serial Communication Interface of SCI, the same as previous years. All of
the information about the functioning of all the system is organized, controlled, and communicated
by the CCD bus, which is described in Section 3 (CCD Bus) of this general information section.
Through the CCD bus, information about the operation of vehicle components and circuits is
relayed quickly to the appropriate module(s). All modules receive all the information transmitted on
the bus even though a module may not require all the information to perform it's function. It will only
respond to messages "addressed" to it through a binary coding process. This method of data
transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring
harnesses.

Camshaft Position Sensor: Description and Operation
SYSTEM OPERATION
The camshaft position sensor is located in the distributor on all engines.
The sensor contains a hall effect device called a sync signal generator to generate a fuel sync
signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The
pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction
with the crankshaft position sensor to differentiate between fuel injection and spark events. It is
also used to synchronize the fuel injectors with their respective cylinders.
When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following
occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync
signal of approximately 5 volts.
When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following
occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts.

Camshaft Position Sensor: Testing and Inspection
Camshaft Position Sensor - Typical
The camshaft position sensor is located in the distributor on all engines.
To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain
Diagnostics Procedures service. To test the sensor only, refer to the following:
For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector
from the distributor. Using small paper clips, insert them into the backside of the distributor wire
harness connector to make contact with the terminals. Be sure that the connector is not damaged
when inserting the paper clips. Attach voltmeter leads to these paper clips.
1. Remove engine cover. 2. Connect the positive (+) voltmeter lead into the sensor output wire.
This is at done the distributor wire harness connector. For wire identification. 3. Connect the
negative (-) voltmeter lead into the ground wire. For wire identification. 4. Set the voltmeter to the
15 Volt DC scale. 5. Remove distributor cap from distributor (two screws). Rotate (crank) the
engine until the distributor rotor is pointed towards the rear of vehicle.
The movable pulse ring should now be within the sensor pickup.
6. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 7. If voltage is
not present, check the voltmeter leads for a good connection. 8. If voltage is still not present, check
for voltage at the supply wire. For wire identification. 9. If 5 volts is not present at supply wire,
check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for
this
test.
10. If voltage is still not present, perform vehicle test using the DRB scan tool. 11. If voltage is
present at cavity A-17, but not at the supply wire:
a. Check continuity between the supply wire. This is checked between the distributor connector and
cavity A-17 at the PCM. If continuity is not
present, repair the harness as necessary
b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the
PCM. If continuity is not present, repair the
harness as necessary
c. Check for continuity between the ground circuit wire at the distributor connector and ground. If
continuity is not present, repair the harness as
necessary.
12. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle
should fluctuate between 0 and 5 volts while the
engine is cranking. This verifies that the camshaft position sensor in the distributor is operating
properly and a sync pulse signal is being generated. If sync pulse signal is not present,
replacement of the camshaft position sensor is necessary.

Crankshaft Position Sensor: Description and Operation
SYSTEM OPERATION
Sensor Operation
Engine speed and crankshaft position are provided through the crankshaft position sensor. The
sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM
interprets the sensor input to determine the crankshaft position. The PCM then uses this position,
along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
On this engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its
outer edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM. For each engine revolution, there are 8 pulses generated on V-8 engines.
The engine will not operate if the PCM does not receive a crankshaft position sensor input.

Owner Letter
EMISSIONS RECALL TO REPROGRAM YOUR VEHICLE'S POWERTRAIN CONTROL MODULE
Dear DaimlerChrysler Vehicle Owner:
DaimlerChrysler has determined that some 1998 Dodge Dakota, Durango, Ram Van/Wagon, Ram
Truck, and Jeep(R) Grand Cherokee vehicles, equipped with a V-8 or V-10 engine, may be in
violation of California Emissions Regulations.
The problem is...
The On-Board Diagnostic (OBD) system on your vehicle (identified on the enclosed form) may not
detect evaporative emissions purge system malfunctions as required by California Emissions
Regulations. As a result, the OBD system on your vehicle may not illuminate the "Check Engine"
light if the evaporative emissions purge system malfunctions. This could cause your vehicle to emit
hydrocarbon levels above the limits that were established to protect the public health from the
dangers of air pollution.
Hydrocarbons (unburned fuel) combined with oxides of nitrogen, in the presence of sunlight, can
cause the formation of ozone. These pollutants are the primary components of smog.
What DaimlerChrysler and your dealer will do...
DaimlerChrysler will repair your vehicle free of charge (parts and labor). To do this, your dealer will
reprogram your vehicle's powertrain control module. The work will take about 1/2 hour to complete.
However, additional time may be necessary depending on how dealer appointments are scheduled
and processed.
What you must do...
^ Simply contact your dealer right away to schedule a service appointment.
^ Bring the enclosed Owner Notification form with you to your dealer. It identifies the required
service to the dealer.
If you live in California and don't get this done...
The State of California requires the completion of emission recall repairs prior to vehicle
registration renewal. In addition, the State requires that every vehicle must pass an emission test
(SMOG Check) every two years and before it is sold. Without the free service we are providing,
your vehicle may be more likely to fail this test and require that you make costly repairs.
How the state knows that the recall has been performed...
State of California regulations require DaimlerChrysler to provide the Department of Motor Vehicles
with a record of all vehicles that have not had the recall service performed. If you live in the state of
California and your vehicle is not on this list, the state will know that the recall has been completed.
Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the
recall service is completed. Be sure to save this form since the California Department of Motor
Vehicles may require that you supply it as proof of recall completion.
If you need help...
If you have trouble getting your vehicle repaired, please call the DaimlerChrysler Customer
Assistance Center, toll free, at 1-800-992-1997. A representative will assist you in getting your
vehicle repaired.
In order to ensure your full protection under the emission warranty provisions, it is recommended
that you have your vehicle serviced as soon as possible. Failure to do so could be determined as
lack of proper maintenance of your vehicle.
We are sorry for any inconvenience but trust you understand our interest in clean air and your
continued satisfaction with our products. Thank you for your attention to this important matter.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module >
Component Information > Diagrams > Diagram Information and Instructions > Page 2237
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers.
- Connectors located on the instrument panel harness are C200 series numbers.
- Connectors located on the body harness are C300 series numbers.

- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Component Information > Diagrams > Diagram Information and Instructions > Page 2240
Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For

Engine Control Module: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation
Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of
the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module >
Component Information > Diagrams > Diagram Information and Instructions > Page 2252
Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

SYSTEM OPERATION
Powertrain Control Module (PCM)
The Powertrain Control Module (PCM) is located in the engine compartment. The ignition system is
controlled by the PCM.
NOTE: Base ignition timing by rotation of distributor is not adjustable.
The PCM opens and closes the ignition coil ground circuit to operate the ignition coil. This is done
to adjust ignition timing, both initial (base) and advance, and for changing engine operating
conditions. The amount of electronic spark advance provided by the PCM is determined by five
input factors: engine coolant temperature, engine rpm, intake manifold temperature, manifold
absolute pressure and throttle position.

Malfunction Indicator Lamp: Description and Operation
Data Link Connector
As a functional test, the MIL (check engine) illuminates at key-on before engine cranking.
Whenever the Powertrain Control Module (PCM) sets a Diagnostic Trouble Code (DTC) that affects
vehicle emissions, it illuminates the MIL. If a problem is detected, the PCM sends a message to the
instrument cluster to illuminate the lamp. The PCM illuminates the MIL only for DTC's that affect
vehicle emissions. There are some monitors that may take two consecutive trips, with a detected
fault, before the MIL is illuminated. The MIL stays on continuously when the PCM has entered a
Limp-In mode or identified a failed emission component. Also, the MIL either flashes or illuminates
continuously when the PCM detects active engine misfire.
Additionally, the PCM may reset (turn off) the MIL when one of the following occur:
^ PCM does not detect the malfunction for 3 consecutive trips (except misfire and Fuel system
Monitors).
^ PCM does not detect a malfunction while performing three successive engine misfire or fuel
system tests. The PCM performs these tests while the engine is operating within ± 375 RPM of and
within 10 % of the load of the operating condition at which the malfunction was first detected.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Instructions > Page 2318
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers.
- Connectors located on the instrument panel harness are C200 series numbers.
- Connectors located on the body harness are C300 series numbers.

Instructions > Page 2320
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Instructions > Page 2321
Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.
- ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE
CLOTHING.

various engine solenoids.
Positive Temperature Coefficient Symbol
A special symbol is used to identify these in the wiring diagrams.
Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Body Control Module: Description and Operation System Description and Functional Operation
The body system on the 1998 AB HIGH LINE consists of three modules that communicate over the
CCD bus (Chrysler Collision Detection multiplex system). There are two additional modules, the
Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the
body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for
diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are
performed through the Serial Communication Interface of SCI, the same as previous years. All of
the information about the functioning of all the system is organized, controlled, and communicated
by the CCD bus, which is described in Section 3 (CCD Bus) of this general information section.
Through the CCD bus, information about the operation of vehicle components and circuits is
relayed quickly to the appropriate module(s). All modules receive all the information transmitted on
the bus even though a module may not require all the information to perform it's function. It will only
respond to messages "addressed" to it through a binary coding process. This method of data
transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring
harnesses.

Owner Letter
EMISSIONS RECALL TO REPROGRAM YOUR VEHICLE'S POWERTRAIN CONTROL MODULE
Dear DaimlerChrysler Vehicle Owner:
DaimlerChrysler has determined that some 1998 Dodge Dakota, Durango, Ram Van/Wagon, Ram
Truck, and Jeep(R) Grand Cherokee vehicles, equipped with a V-8 or V-10 engine, may be in
violation of California Emissions Regulations.
The problem is...
The On-Board Diagnostic (OBD) system on your vehicle (identified on the enclosed form) may not
detect evaporative emissions purge system malfunctions as required by California Emissions
Regulations. As a result, the OBD system on your vehicle may not illuminate the "Check Engine"
light if the evaporative emissions purge system malfunctions. This could cause your vehicle to emit
hydrocarbon levels above the limits that were established to protect the public health from the
dangers of air pollution.
Hydrocarbons (unburned fuel) combined with oxides of nitrogen, in the presence of sunlight, can
cause the formation of ozone. These pollutants are the primary components of smog.
What DaimlerChrysler and your dealer will do...
DaimlerChrysler will repair your vehicle free of charge (parts and labor). To do this, your dealer will
reprogram your vehicle's powertrain control module. The work will take about 1/2 hour to complete.
However, additional time may be necessary depending on how dealer appointments are scheduled
and processed.
What you must do...
^ Simply contact your dealer right away to schedule a service appointment.
^ Bring the enclosed Owner Notification form with you to your dealer. It identifies the required
service to the dealer.
If you live in California and don't get this done...
The State of California requires the completion of emission recall repairs prior to vehicle
registration renewal. In addition, the State requires that every vehicle must pass an emission test
(SMOG Check) every two years and before it is sold. Without the free service we are providing,
your vehicle may be more likely to fail this test and require that you make costly repairs.
How the state knows that the recall has been performed...
State of California regulations require DaimlerChrysler to provide the Department of Motor Vehicles
with a record of all vehicles that have not had the recall service performed. If you live in the state of
California and your vehicle is not on this list, the state will know that the recall has been completed.
Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the
recall service is completed. Be sure to save this form since the California Department of Motor
Vehicles may require that you supply it as proof of recall completion.
If you need help...
If you have trouble getting your vehicle repaired, please call the DaimlerChrysler Customer
Assistance Center, toll free, at 1-800-992-1997. A representative will assist you in getting your
vehicle repaired.
In order to ensure your full protection under the emission warranty provisions, it is recommended
that you have your vehicle serviced as soon as possible. Failure to do so could be determined as
lack of proper maintenance of your vehicle.
We are sorry for any inconvenience but trust you understand our interest in clean air and your
continued satisfaction with our products. Thank you for your attention to this important matter.

How the state knows that the recall has been performed...
State of California regulations require DaimlerChrysler to provide the Department of Motor Vehicles
with a record of all vehicles that have not had the recall service performed. If you live in the state of
California and your vehicle is not on this list, the state will know that the recall has been completed.
Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the
recall service is completed. Be sure to save this form since the California Department of Motor
Vehicles may require that you supply it as proof of recall completion.
If you need help...
If you have trouble getting your vehicle repaired, please call the DaimlerChrysler Customer
Assistance Center, toll free, at 1-800-992-1997. A representative will assist you in getting your

Whenever any connector on the PCM is disconnected, the ignition switch must be in the "OFF"
position for a minimum of 5 seconds before connector removal.
It has been found under certain key "ON" or momentary key "OFF" conditions, when the black
connector is unplugged, the PCM may attempt to write information to the EEPROM processor
within the PCM. Sometimes this inadvertent write will set the target charging voltage to 0 (zero)
volts. The result will prevent the charging system from charging the battery.
If this occurs, the only correction is PCM replacement.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
Circuit Function

Dodge 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 2392
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers.
- Connectors located on the instrument panel harness are C200 series numbers.
- Connectors located on the body harness are C300 series numbers.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge 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 2394
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Dodge 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 2395
Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.
- ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE
CLOTHING.
Positive Temperature Coefficient
Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's
act like a solid state fuse. They are located in the

junction block, and are used to protect such items as: power door lock motors, power windows, and
various engine solenoids.
Positive Temperature Coefficient Symbol
A special symbol is used to identify these in the wiring diagrams.
Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.
Symbols

International symbols are used throughout the wiring diagrams. These symbols are consistent with
those being used around the world.
Take-Outs
The abbreviation T/O is used in the Component Location group to indicate a point at which the
wiring harness branches out to a component.
How to Find System & Component Diagrams
When trying to find the diagram for a specific component or system, use the Group Index
information or the Alphabetic Index to Wiring Diagrams under Electrical
Whenever a reference exists to another sheet or figure, find the corresponding diagram using the
Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number
for the subsequent diagram will match a listed group shown.

Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation
Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of
the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check

Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Engine Control Module: Description and Operation
SYSTEM OPERATION
Powertrain Control Module (PCM)
The Powertrain Control Module (PCM) is located in the engine compartment. The ignition system is
controlled by the PCM.
NOTE: Base ignition timing by rotation of distributor is not adjustable.
The PCM opens and closes the ignition coil ground circuit to operate the ignition coil. This is done
to adjust ignition timing, both initial (base) and advance, and for changing engine operating
conditions. The amount of electronic spark advance provided by the PCM is determined by five
input factors: engine coolant temperature, engine rpm, intake manifold temperature, manifold
absolute pressure and throttle position.

Camshaft Position Sensor: Description and Operation
SYSTEM OPERATION
The camshaft position sensor is located in the distributor on all engines.
The sensor contains a hall effect device called a sync signal generator to generate a fuel sync
signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The
pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction
with the crankshaft position sensor to differentiate between fuel injection and spark events. It is
also used to synchronize the fuel injectors with their respective cylinders.
When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following
occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync
signal of approximately 5 volts.
When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following
occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts.

Camshaft Position Sensor: Testing and Inspection
Camshaft Position Sensor - Typical
The camshaft position sensor is located in the distributor on all engines.
To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain
Diagnostics Procedures service. To test the sensor only, refer to the following:
For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector
from the distributor. Using small paper clips, insert them into the backside of the distributor wire
harness connector to make contact with the terminals. Be sure that the connector is not damaged
when inserting the paper clips. Attach voltmeter leads to these paper clips.
1. Remove engine cover. 2. Connect the positive (+) voltmeter lead into the sensor output wire.
This is at done the distributor wire harness connector. For wire identification. 3. Connect the
negative (-) voltmeter lead into the ground wire. For wire identification. 4. Set the voltmeter to the
15 Volt DC scale. 5. Remove distributor cap from distributor (two screws). Rotate (crank) the
engine until the distributor rotor is pointed towards the rear of vehicle.
The movable pulse ring should now be within the sensor pickup.
6. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 7. If voltage is
not present, check the voltmeter leads for a good connection. 8. If voltage is still not present, check
for voltage at the supply wire. For wire identification. 9. If 5 volts is not present at supply wire,
check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for
this
test.
10. If voltage is still not present, perform vehicle test using the DRB scan tool. 11. If voltage is
present at cavity A-17, but not at the supply wire:
a. Check continuity between the supply wire. This is checked between the distributor connector and
cavity A-17 at the PCM. If continuity is not
present, repair the harness as necessary
b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the
PCM. If continuity is not present, repair the
harness as necessary
c. Check for continuity between the ground circuit wire at the distributor connector and ground. If
continuity is not present, repair the harness as
necessary.
12. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle
should fluctuate between 0 and 5 volts while the
engine is cranking. This verifies that the camshaft position sensor in the distributor is operating
properly and a sync pulse signal is being generated. If sync pulse signal is not present,
replacement of the camshaft position sensor is necessary.

Crankshaft Position Sensor: Description and Operation
SYSTEM OPERATION
Sensor Operation
Engine speed and crankshaft position are provided through the crankshaft position sensor. The
sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM
interprets the sensor input to determine the crankshaft position. The PCM then uses this position,
along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
On this engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its
outer edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM. For each engine revolution, there are 8 pulses generated on V-8 engines.
The engine will not operate if the PCM does not receive a crankshaft position sensor input.

Throttle Position Sensor: Testing and Inspection
The Throttle Position Sensor (TPS) can be tested with a digital voltmeter. The center terminal of
the TPS is the output terminal.
With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of
the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT).
- At idle, TPS output voltage should should be greater than 0.350 millivolts and less than 900
millivolts.
- At wide open throttle, TPS output voltage must be less than 4.5 volts.
- The output voltage should increase gradually as the throttle plate is slowly opened from idle to
WOT.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Instructions > Page 2522
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers.
- Connectors located on the instrument panel harness are C200 series numbers.
- Connectors located on the body harness are C300 series numbers.

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and
Instructions > Page 2524
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.
- ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE
CLOTHING.
Positive Temperature Coefficient
Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's
act like a solid state fuse. They are located in the

junction block, and are used to protect such items as: power door lock motors, power windows, and
various engine solenoids.
Positive Temperature Coefficient Symbol
A special symbol is used to identify these in the wiring diagrams.
Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

International symbols are used throughout the wiring diagrams. These symbols are consistent with
those being used around the world.
Take-Outs
The abbreviation T/O is used in the Component Location group to indicate a point at which the
wiring harness branches out to a component.
How to Find System & Component Diagrams
When trying to find the diagram for a specific component or system, use the Group Index
information or the Alphabetic Index to Wiring Diagrams under Electrical
Whenever a reference exists to another sheet or figure, find the corresponding diagram using the
Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number
for the subsequent diagram will match a listed group shown.

Vehicle Speed Sensor: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation
Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of
the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check
voltage. Refer to the
appropriate test procedure.

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and
Instructions > Page 2537
Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Vehicle Speed Sensor: Description and Operation
VEHICLE SPEED AND DISTANCE-PCM INPUT
The Vehicle Speed Sensor (VSS) is no longer used for any Dodge truck in the 1998 model year.
Vehicle speed and distance covered are measured by the Rear Wheel Speed Sensor. See: Brakes
and Traction Control/Antilock Brakes / Traction Control Systems/Wheel Speed Sensor The sensor
is mounted to the rear axle. A signal is sent from this sensor to the Controller Antilock Brake (CAB)
computer. A signal is then sent from the CAB to the Powertrain Control Module (PCM) to determine
vehicle speed and distance covered. The PCM will then determine strategies for fuel system and
speed control system operation.

Throttle Position Sensor: Testing and Inspection
The Throttle Position Sensor (TPS) can be tested with a digital voltmeter. The center terminal of
the TPS is the output terminal.
With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of
the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT).
- At idle, TPS output voltage should should be greater than 0.350 millivolts and less than 900
millivolts.
- At wide open throttle, TPS output voltage must be less than 4.5 volts.
- The output voltage should increase gradually as the throttle plate is slowly opened from idle to
WOT.
NOTE: For additional testing information and circuit diagnosis see Computers and Control
Systems/System Diagnosis/Procedures/Diagnostic Charts.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.

Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Vehicle Speed Sensor: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Canister Purge Solenoid: Description and Operation
EVAP Purge Solenoid And LDP
DESCRIPTION
All engines use a duty cycle EVAP canister purge solenoid. The solenoid regulates the rate of
vapor flow from the EVAP canister to the throttle body. The Powertrain Control Module (PCM)
operates the solenoid.
OPERATION
During the cold start warm-up period and the hot start time delay, the PCM does not energize the
solenoid. When de-energized, no vapors are purged. The PCM deenergizes the solenoid during
open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay
ends. During closed loop operation, the PCM energizes and de-energizes the solenoid 5 or 10
times per second, depending upon operating conditions. The PCM varies the vapor flow rate by
changing solenoid pulse width. Pulse width is the amount of time the solenoid energizes. The PCM
adjusts solenoid pulse width based on engine operating condition.
CIRCUIT OPERATION
The Powertrain Control Module (PCM) operates the EVAP/Purge solenoid by providing a ground
path on circuit K52. Circuit K52 connects to PCM cavity C20. Circuit F18 supplies battery voltage to
the EVAP/Purge solenoid.

DISCUSSION: During evaporative system diagnosis, Leak Detection Pumps have mistakenly been
replaced. A thorough inspection for pinched, kinked, or disconnected supply vacuum lines (as
currently listed in the Powertrain Diagnostic Procedures) is a critical step in diagnosing DTC P1494
(LDP SW OR MECHANICAL FAULT). Additionally, the other evaporative leak faults (DTC P0442 SMALL LEAK, P0455 - LARGE LEAK, and P0456 - VERY SMALL LEAK) should have the supply
vacuum lines examined for pinches or kinks prior to any LDP component replacement.
The supply vacuum lines should be checked from the engine compartment all the way to the fuel
tank, including the LDP and purge system.
NOTE:
VERIFY ALL RELATED SUPPLY VACUUM LINE ROUTINGS FOR PINCHES, KINKS, OR
DISCONNECTION'S BEFORE REPLACING LDP SYSTEM COMPONENTS.

INTRODUCTION
The evaporative emission system is designed to prevent the escape of fuel vapors from the fuel
system. Leaks in the system, even small ones, can allow fuel vapors to escape into the
atmosphere. Government regulations require on-board testing to make sure that the evaporative
(EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and
blockage. It also performs self-diagnostics.
During self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection
Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the
LDP to seal the vent valve and pump air into the system to pressurize
it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The
PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to
maintain pressure in the system.

EVAP LEAK DETECTION SYSTEM COMPONENTS
Service Port: Used with special tools like the Miller Evaporative Emissions Leak Detector (EELD) to
test for leaks in the system.
EVAP Purge Solenoid: The PCM uses the EVAP purge solenoid to control purging of excess fuel
vapors stored in the EVAP canister. It remains closed during leak testing to prevent loss of
pressure.
EVAP Canister The EVAP canister stores fuel vapors from the fuel tank for purging. EVAP Purge
Orifice: Limits purge volume.
EVAP System Air Filter: Provides air to the LDP for pressurizing the system. It filters out dirt while
allowing a vent to atmosphere for the EVAP system.
Leak Detection Pump (LDP) Components
The main purpose of the LDP is to pressurize the fuel system for leak checking. It closes the EVAP
system vent to atmospheric pressure so the system can be pressurized for leak testing. The
diaphragm is powered by engine vacuum. It pumps air into the EVAP system to develop a pressure
of about 7.5' H20(1/4) psi. A reed switch in the LDP allows the PCM to monitor the position of the
LDP diaphragm. The PCM uses the reed switch input to monitor how fast the LDP is pumping air
into the EVAP system. This allows detection of leaks and blockage.
The LDP assembly consists of several parts. The solenoid is controlled by the PCM, and it
connects the upper pump cavity to either engine vacuum or atmospheric pressure. A vent valve
closes the EVAP system to atmosphere, sealing the system during leak testing. The pump section
of the LDP consists of a diaphragm that moves up and down to bring air in through the air filter and
inlet check valve, and pump it out through an outlet check valve into the EVAP system.
The diaphragm is pulled up by engine vacuum, and pushed down by spring pressure, as the LDP
solenoid turns on and off. The LDP also has a magnetic reed switch to signal diaphragm position to
the PCM. When the diaphragm is down, the switch is closed, which sends a 12 V (system voltage)
signal to the PCM. When the diaphragm is up, the switch is open, and there is no voltage sent to
the PCM. This allows the PCM to monitor LDP pumping action as it turns the LDP solenoid on and
off.

Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2624
LDP AT REST (NOT POWERED)
When the LDP is at rest (no electrical/vacuum) the diaphragm is allowed to drop down if the
internal (EVAP system) pressure is not greater than the return spring. The LDP solenoid blocks the
engine vacuum port and opens the atmospheric pressure port connected through the EVAP system
air filter. The vent valve is held open by the diaphragm. This allows the canister to see atmospheric
pressure.

Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2625
DIAPHRAGM UPWARD MOVEMENT
When the PCM energizes the LDP solenoid, the solenoid blocks the atmospheric port leading
through the EVAP air filter and at the same time opens the engine vacuum port to the pump cavity
above the diaphragm. The diaphragm moves upward when vacuum above the diaphragm exceeds
spring force. This upward movement closes the vent valve. It also causes low pressure below the
diaphragm, unseating the inlet check valve and allowing air in from the EVAP air filter. When the
diaphragm completes its upward movement, the LDP reed switch turns from closed to open.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak
Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2626
DIAPHRAGM DOWNWARD MOVEMENT based on reed switch input, the PCM de-energizes the
LDP solenoid, causing it to block the vacuum port, and open the atmospheric port. This connects
the upper pump cavity to atmosphere through the EVAP air filter. The spring is now able to push
the diaphragm down. The downward movement of the diaphragm closes the inlet check valve and
opens the outlet check valve pumping air into the evaporative system. The LDP reed switch turns
from open to closed, allowing the PGM to monitor LDP pumping (diaphragm up/down) activity.
During the pumping mode, the diaphragm will not move down far enough to open the vent valve
The pumping cycle is repeated as the solenoid is turned on and off. When the evaporative system
begins to pressurize, the pressure on the bottom of the diaphragm will begin to oppose the spring
pressure, slowing the pumping action. The PCM watches the time from when the solenoid is
de-energized, until the diaphragm drops down far enough for the reed switch to change from
opened to closed. If the reed switch changes too quickly, a leak may be indicated. The longer it
takes the reed switch to change state, the tighter the evaporative system is sealed. If the system
pressurizes too quickly, a restriction somewhere in the EVAP system may be indicated.
PUMPING ACTION During portions of this test, the PCM uses the reed switch to monitor
diaphragm movement. The solenoid is only turned on by the PCM after the reed switch changes
from open to closed, indicating that the diaphragm has moved down. At other times during the test,
the PCM will rapidly cycle the LDP solenoid on and off to quickly pressurize the system. During
rapid cycling, the diaphragm will not move enough to change the reed switch state. In the state of
rapid cycling, the PCM will use a fixed time interval to cycle the solenoid.

ENABLING CONDITIONS TO RUN EVAP LEAK DETECTION TEST
NOTE: The following values are approximate and vehicle specific. Use the values seen in pre
test/monitor test screen on the DRB III. See TSB 25-02-98 for more detail
1. Cold start: with ambient temperature (obtained from modeling the inlet air temperature sensor on

Figure 6
EVAP leak detection test sequence
When the ignition key is turned to "ON" the LDP diaphragm should be in the down position and the
LDP reed switch should be closed. If the EVAP system has residual pressure, the LDP diaphragm
may be up. This could result in the LDP reed switch being open when the key is turned to "ON" and
a P1494 fault could be set because the PCM is expecting the reed switch to be closed.
After the key is turned "ON", the PCM immediately tests the LDP solenoid circuit for electrical
faults. If a fault is detected, DTC P1495 will set, the MIL will illuminate, and the remaining EVAP
Leak Detection Test is canceled.
NOTE: If battery temperature is not within range, or if the engine coolant temperature is not within a
specified range of the battery temperature, the PCM will not run tests for DTC P1494, P1486,
P0442, P0455 and P0441. These temperature calibrations may be different between models.
FIGURE 6 SECTION 2
If DTC P1495 is not set, the PCM will check for DTC P1494. If the LDP reed switch was closed
when the key was turned to "ON", the PCM energizes the LDP solenoid for up to 8 seconds and
monitors the LDP switch. As the LDP diaphragm is pulled up by engine vacuum, the LDP reed
switch should change from closed to open. If it does not, the PCM sets a temporary fault (P1494) in
memory, and waits until the next time the Enabling Conditions are met to run the test again. If this
is again detected, P1494 is stored and the MIL is illuminated. If the problem is not detected during
the next enabling cycle, the temporary fault will be cleared.
However, if the PCM detects the reed switch open when the key is turned to "ON", the PCM must
determine if this condition is due to residual pressure in the EVAP system, or an actual fault. The
PCM stores information in memory on EVAP system purging from previous engine run or drive
cycles.
If little or no purging took place, residual pressure could be holding the LDP diaphragm up, causing
the LDP switch to be open. Since this is not a malfunction, the PCM cancels the EVAP Leak
Detection Test without setting the temporary fault.
If there was sufficient purging during the previous cycle to eliminate EVAP system pressure, the
PCM judges that this is a malfunction and sets a temporary fault in memory. The next time that the
Enabling Conditions are met, the test will run again. If the fault is again detected, the MIL will

Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2629
illuminate and DTC 1494 will be stored. If the fault is not detected, the temporary fault will be
cleared.
FIGURE 6 SECTION 3
If no fault has been detected so far, the PCM begins testing for possible blockage in the EVAP
system between the LDP and the fuel tank. This is done by monitoring the time required for the
LDP to pump air into the EVAP system during two to three pump cycles. If no blockage is present,
the LDP diaphragm is able to quickly pump air out of the LDP each time the PCM turns oft the LDP
solenoid. If a blockage is present, the PCM detects that the LDP takes longer to complete each
pump cycle. If the pump cycles take longer than expected (approximately 6 to 10 seconds) the
PCM will suspect a blockage. On the next drive when Enabling Conditions are met, the test will run
again. If blockage is again detected, P1486 is stored, and the MIL is illuminated.
FIGURE 6 SECTION 4
After the LDP blockage tests are completed, the PCM then tests for EVAP system leakage. First,
the PCM commands the LDP to rapidly pump for 20 to 50 seconds (depending on fuel level) to
build pressure in the EVAP system. This evaluates the system J18-24-0 to see if it can be
sufficiently pressurized. This evaluation (rapid pump cycling) may occur several times prior to leak
checking. The LDP reed switch does not close and open during rapid pumping because the
diaphragm does not travel through its full range during this part of the test.
FIGURE 6 SECTION 5
Next, the PCM performs one or more test cycles by monitoring the time required for the LDP reed
switch to close (diaphragm to drop) after the LDP solenoid is turned off.
If the switch does not close, or closes after a long delay, it means that the system does not have
any significant leakage and the EVAP Leak Detection Test is complete.
However, if the LDP reed switch closes quickly, there may be a leak or the fuel level may be low
enough that the LDP must pump more to finish pressurizing the EVAP system. In this case, the
PCM will rapidly pump the LDP again to build pressure in the EVAP system, and follow that by
monitoring the time needed for several LDP test cycles. This process of rapid pumping followed by
several LDP test cycles may repeat several times before the PCM judges that a leak is present.
When leaks are present, the LDP test cycle time will be inversely proportional to the size of the
leak. The larger the leak, the shorter the test cycle time. The smaller the leak, the longer the test
cycle time. DTC's may be set when a leak as small as 0.5 mm (0.020") diameter is present.
If the system detects a leak, a temporary fault will be stored in PCM memory. The time it takes to
detect a .020, .040, or Large leak is based on calibrations that vary from model to model. The
important point to remember is if a leak is again detected on the next EVAP Leak Detection Test,
the MIL will illuminate and a DTC will be stored based on the size of leak detected. If no leak is
detected during the next test, the temporary fault will be cleared.
DIAGNOSTIC TIPS
During diagnosis, you can compare the LDP solenoid activity with the monitor sequence in Figure
6. If the PCM detects a problem that could set a DTC, the testing is halted and LDP solenoid
activity will stop. As each section of the test begins, it indicates that the previous section passed
successfully. By watching to see which tests complete, you can see if any conditions are present
that the PCM considers abnormal.
For example, if the LDP solenoid is energized for the test cycles to test for blockage (P1486), it
means that the LDP has already passed its test for P1494. Then, if the PCM detects a possible
blockage, it will set a temporary fault without turning on the MIL and continue the leak portion of the
test. However, the PCM will assume that the system is already pressurized and skip the rapid
pump cycles.
Always diagnose leaks, if possible, before disconnecting connections. Disconnecting connections
may mask a leak condition.
Keep in mind that if the purge solenoid seat is leaking, it could go undetected since the leak would
end up in the intake manifold. Disconnect the purge solenoid at the manifold when leak checking.
In addition, a pinched hose fault (P1486) could set if the purge solenoid does not purge the fuel
system properly (blocked seat). The purge solenoid must vent the fuel system prior to the LDP
system test. If the purge solenoid cannot properly vent the system the LDP cannot properly
complete the test for P1486 and this fault can set due to pressure being in the EVAP system during
the test sequence.
Multiple actuation's of the DRB Ill® Leak Detection Pump (LDP) Monitor Test can hide a 0.020 leak
because of excess vapor generation. Additionally, any source for additional vapor generation can
hide a small leak in the EVAP system. Excess vapor generation can delay the fall of the LDP
diaphragm thus hiding the small leak. An example of this condition could be bringing a cold vehicle
into a warm shop for testing or high ambient temperatures.
Fully plugged and partially plugged underhood vacuum lines have been known to set MIL
conditions. P1494 and P0456 can be set for this reason. Always, thoroughly, check plumbing for
pinches or blockage before condemning components.
TEST EQUIPMENT
The Evaporative Emission Leak Detector (EELD) Miller Special Tool 8404 is capable of visually
detecting leaks in the evaporative system and will take

Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2630
the place of the ultrasonic leak detector 6917A. The EELD utilizes shop air and a smoke generator
to visually detect leaks down to 0.020 or smaller. The food grade oil used to make the smoke
includes an UV trace dye that will leave telltale signs of the leak under a black light. This is helpful
when components have to be removed to determine the exact leak location. For detailed test
instructions, follow the operators manual packaged with the EELD.
IMPORTANT
Be sure that the PCM has the latest software update. Reprogram as indicated by any applicable
Technical Service Bulletin. After LDP repairs are completed, verify the repair by running the DRB
Ill® Leak Detection Pump (LDP) Monitor Test as described in Technical Service Bulletin 18-12-99.

Fuel Pressure: Capacity Specifications
NOTE: Before performing this test, verify fuel pump pressure by performing the Fuel Pump
Pressure Test. Use this test in conjunction with the Fuel Pressure Leak Down Test.
1. Release fuel system pressure.
- Refer to the Fuel Pressure Release Procedure.
2. Disconnect the fuel supply line at fuel rail.
- Some engines may require air cleaner housing removal before line disconnection.
3. Connect appropriate Fuel Line Pressure Test Adapter Tool Hose (number 6631, 6923, 6541 or
6539) into disconnected fuel supply line.
- Insert other end of Adaptor Tool hose into a graduated container.
4. Remove the fuel fill cap. 5. To activate fuel pump and pressurize system, obtain DRB scan tool
and actuate ASD Fuel System Test. 6. A good fuel pump will deliver at least 1/4 liter of fuel in 7
seconds.
- Do not operate fuel pump for longer than 7 seconds with fuel line disconnected as fuel pump
module reservoir may run empty.
a. If capacity is lower than specification, but fuel pump can be heard operating through fuel fill cap
opening, check for a kinked/damaged fuel
supply line somewhere between fuel rail and fuel pump module.
b. If line is not kinked/damaged, and fuel pressure is OK, but capacity is low, replace fuel filter/ fuel
pressure regulator. The filter/regulator may be serviced separately on certain applications.
- Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information.
c. If both fuel pressure and capacity are low, replace fuel pump module assembly. Refer to Fuel Pump Module Removal/Installation.

NOTE: Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity
Test.
Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational.
After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid
gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure
that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the
electric fuel pump is activated, fuel pressure should immediately rise to specification.
Abnormally long periods of cranking to restart a hot engine that has been shut down for a short
period of time may be caused by: Fuel pressure bleeding past a fuel injector(s).
- Fuel pressure bleeding past the check valve in the fuel pump module.
1. Disconnect the fuel inlet line at fuel rail.
- On some engines, air cleaner housing removal may be necessary before fuel line disconnection.
2. Connect the appropriate Fuel Line Pressure Test Adapter Tool (number 6539, 6631, 6541 or
6923) between the disconnected fuel line and fuel rail
(Fig. 9) or (Fig. 10).
3. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test
port on the appropriate Adaptor Tool.
- The fittings on both tools must be in good condition and free from any small leaks before
performing the proceeding test.
4. Start engine and bring to normal operating temperature.

5. Observe test gauge. Normal operating pressure should be 339 kPa +/- 34 kPa (49.2 psi +/- 5
psi). 6. Shut engine off. 7. Pressure should not fall below 30 psi for five minutes. 8. If pressure falls
below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module,
or a fuel tube/line is leaking. 9. Again, start engine and bring to normal operating temperature.
10. Shut engine off. 11. Testing for fuel injector or fuel rail leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on
Adapter Tool.
- If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking.
12. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T"
on Adapter Tool.
- If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line.
- If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump
or filter/ regulator may be leaking.
NOTE: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A
slow loss of pressure usually indicates a defective check valve in the electric fuel pump.
The electric fuel pump is not serviced separately -- Replace the fuel pump module assembly. The

Fuel Pressure: Testing and Inspection Fuel Pressure Test
Fuel Pressure Test Gauge
NOTE: Use this test in conjunction with the Fuel Pump Capacity Test, Fuel Pressure Leak Down
Test, fuel pump amperage test.
Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow hack into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational. After the vehicle has cooled down fuel pressure may drop to 0 psi (cold fluid
contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel
injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal
condition. When the electric fuel pump is activated, fuel pressure should immediately rise to
specification.
All fuel systems are equipped with a fuel tank module mounted, combination fuel filter/fuel pressure
regulator. The fuel pressure regulator is not controlled by engine vacuum.
WARNING: The fuel system is under constant fuel pressure even with the engine off. Before
disconnecting fuel line at fuel rail, this pressure must be released. Refer to the fuel system
pressure release procedure.
NOTE: To perform this test you will need to remove the engine cover.
1. Remove the protective cap at the fuel rail test port. Connect the 0-414 kPa (0-60 psi) fuel
pressure gauge (from gauge set 5069) to the test port
pressure fitting on the fuel rail.
2. Start and warm the engine and note pressure gauge reading. Fuel pressure should be 3.39 kPa
+/- 34 kPa (49.2 psi +/- 5 psi) at idle. 3. If engine runs but pressure is below 44.2 psi, check for a
kinked fuel supply line somewhere between fuel rail and fuel pump module. If line is not
kinked, replace fuel pump module assembly. Refer to Fuel Pump Removal/Installation.
4. If operating pressure is above 54.2 psi, electric fuel pump is OK, but fuel pressure regulator is
defective. Replace fuel filter/fuel pressure regulator.
Certain filter/regulators may be serviced separately and some require the replacement of the fuel
pump module assembly Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for more
information.

SYMPTOM/CONDITION:
Long cold start times, warm-up sags, hesitations, and driveway die outs. These symptoms are
most noticeable and severe at moderate ambient temperatures between 4 - 27 degrees C (40 - 80
degrees F).
DISCUSSION:
Gasoline with a high Driveability Index (DI) can cause the above described symptoms. DI is a
measure of the gasolines total volatility, or tendency to vaporize completely. A high DI number is
less volatile than a low DI number. Most premium gasoline sold in the U.S. has a higher (worse) DI
index than regular or mid-grade gasoline. Use of premium gasoline is NOT recommended for
vehicles designed to run on 87 (R+M)/2 regular or 89 (R+M)/2 midgrade gasoline. High DI
gasolines also cause higher emissions for the same reasons they cause driveability problems.
For vehicles that require an octane rating of 91 (R+M)/2, premium is recommended, or possibly
required. Using premium fuel with a higher than recommended octane rating is not recommended.
Owners who experience fuel related cold start and warm up driveability problems should try a
gasoline with the recommended octane rating or different brands of gasoline until they find one that
provides good performance.
The octane quality of gasoline is only a measure of its resistance to spark knock. The use of higher
than recommended octane gasoline under normal operating conditions does NOT improve
startability, idle quality, fuel economy, driveability, acceleration, engine durability, or emissions. In
fact, most higher octane gasolines available in the U.S. have higher DI values than regular
gasoline. Customers are most likely to experience poor driveability with premium gasoline than with
regular.
Some vehicles, such as Viper, Prowler, 5.9L Grand Cherokee, 2.0L Turbo Talon, and 2.0L DOHC
Neon have been specifically designed to take advantage of higher octane. These vehicles may
have higher compression ratios, and/or more aggressive spark calibrations which provide optimum
performance with the specified higher octane. However, other vehicles which are not specifically
designed and calibrated to take advantage of higher octane will not benefit from higher octane.
Some vehicles may experience light spark knock in situations such as trailer towing or climbing
steep sustained grades. Light knock or "ping" under these conditions is not harmful. However, if the
customer is concerned about light knock under these circumstances, the use of 89 (R+M)/2 or
even 91 (R+M)/2 premium gasoline may be temporarily warranted. If a vehicle is experiencing
heavy spark knock on gasoline with its designed octane rating, this may be an indication of
excessive combustion chamber deposits, or some other problem. Combustion chamber deposits
can be removed with Mopar Combustion Chamber Conditioner p/n 04318001. Standard diagnostic
procedures may help in identifying other potential causes of excessive knock.
Some gasoline marketers may advertise that their premium gasoline contains extra detergent
additives. Under provisions of the Clean Air Act, ALL gasoline sold in the U.S. must contain
effective deposit control additives. Nevertheless, if fuel injector or intake valve deposits are
suspected of

Technical Service Bulletins > Engine - High Driveability Index Fuels > Page 2682
contributing to poor performance, occasional use of Mopar Fuel Injector Clean Up p/n 04549613 is
a much less expensive way to maintain engine cleanliness than regular use of premium gasoline.
The charts (Figures 1 & 2) show the negative effects of high DI fuel as related to customer
satisfaction.
If fuel quality is suspected in causing a customers driveability concern, your zone technical office
may be able to provide direction on procedures for fuel sample analysis.

Fuel Filler Cap: Description and Operation
DESCRIPTION
The loss of any fuel or vapor out of filler neck is prevented by the use of a pressure-vacuum fuel
tank filler tube cap.
OPERATION
Relief valves inside the cap will release fuel tank pressure at predetermined pressures. Fuel tank
vacuum will also be released at predetermined values. This cap must be replaced by a similar unit
if replacement is necessary. This is in order for the system to remain effective.
CAUTION: Remove fuel tank filler tube cap before servicing any fuel system component. This is
done to help relieve tank pressure. If equipped with a California emissions package and a Leak
Detection Pump (LDP), the secondary seal below the fill cap must be pressed (opened) to relieve
fuel tank pressure.

Fuel Pressure Leak Down Test
Fig 9 Connecting Adaptor Tool -- Typical
Fig. 8 Installing Adapter Tool And Pressure Gauge
NOTE: Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity
Test.
Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational.
After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid
gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure
that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the
electric fuel pump is activated, fuel pressure should immediately rise to specification.
Abnormally long periods of cranking to restart a hot engine that has been shut down for a short
period of time may be caused by: Fuel pressure bleeding past a fuel injector(s).
- Fuel pressure bleeding past the check valve in the fuel pump module.
1. Disconnect the fuel inlet line at fuel rail.
- On some engines, air cleaner housing removal may be necessary before fuel line disconnection.

2. Connect the appropriate Fuel Line Pressure Test Adapter Tool (number 6539, 6631, 6541 or
6923) between the disconnected fuel line and fuel rail
(Fig. 9) or (Fig. 10).
3. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test
port on the appropriate Adaptor Tool.
- The fittings on both tools must be in good condition and free from any small leaks before
performing the proceeding test.
4. Start engine and bring to normal operating temperature. 5. Observe test gauge. Normal
operating pressure should be 339 kPa +/- 34 kPa (49.2 psi +/- 5 psi). 6. Shut engine off. 7.
Pressure should not fall below 30 psi for five minutes. 8. If pressure falls below 30 psi, it must be
determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is
leaking. 9. Again, start engine and bring to normal operating temperature.
10. Shut engine off. 11. Testing for fuel injector or fuel rail leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on
Adapter Tool.
- If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking.
12. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T"

- If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line.
- If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump
or filter/ regulator may be leaking.
NOTE: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A
slow loss of pressure usually indicates a defective check valve in the electric fuel pump.
The electric fuel pump is not serviced separately -- Replace the fuel pump module assembly. The
filter/ regulator may be replaced separately on certain applications. Refer to Fuel Filter/Fuel
Pressure Regulator Removal/installation for additional information.

Fuel Injector: Description and Operation
Fuel Injector - Typical
DESCRIPTION
The fuel injectors are electrical solenoids. The injector contains a pintle that closes off an orifice at
the nozzle end. When electric current is supplied to the injector, the armature and needle move a
short distance against a spring, allowing fuel to flow out the orifice. Because the fuel is under high
pressure, a fine spray is developed in the shape of a pencil stream. The spraying action atomizes
the fuel, adding it to the air entering the combustion chamber.
OPERATION
An individual fuel injector is used for each individual cylinder. The top (fuel entry) end of the injector
is attached into an opening on the fuel rail. The nozzle outlet) ends of the injectors are positioned
into openings in the intake manifold just above the intake valve ports of the cylinder head. The
engine wiring harness connector for each fuel injector is equipped with an attached numerical tag
(INJ 1, INJ 2 etc.). This is used to identify each fuel injector.
The injectors are energized individually in a sequential order by the powertrain control module
(PCM). The PCM will adjust injector pulse width by switching the ground path to each individual
injector on and off. Injector pulse width is the period of time that the injector is energized. The PCM
will adjust injector pulse width based on various inputs it receives.
During start up, battery voltage is supplied to the injectors through the ASD relay. When the engine
is operating, voltage is supplied by the charging system. The PCM determines injector pulse width
based on various inputs.

Fuel Pressure Regulator: Description and Operation
Fig 3 Side View -- Filter/Pressure Regulator
DESCRIPTION
A combination fuel filter and fuel pressure regulator is used on all engines. It is located on the top
of the fuel pump module. A separate frame mounted fuel filter is not used with any engine.
Both fuel filters (at bottom of fuel pump module and within fuel pressure regulator) are designed for
extended service. They do not require normal scheduled maintenance. Filters should only be
replaced if a diagnostic procedure indicates to do so.
OPERATION
Fuel Pressure Regulator Operation: The pressure regulator is a mechanical device that is not
controlled by engine vacuum or the powertrain control module (PCM).
The regulator is calibrated to maintain fuel system operating pressure of approximately 339 kPa ±
34 kPa (49.2 psi ± 5 psi) at the fuel injectors. It contains a diaphragm, calibrated springs and a fuel
return valve. The internal fuel filter is also part of the assembly
Fuel is supplied to the filter/regulator by the electric fuel pump through an opening tube at the
bottom of filter/regulator. The regulator acts as a check valve to maintain some fuel pressure when
the engine is not operating. This will help to start the engine. A second check valve is located at the
outlet end of the electric fuel pump. If fuel pressure at the pressure regulator exceeds
approximately 49.2 psi, an internal diaphragm opens and excess fuel pressure is routed back into
the tank through the bottom of pressure regulator.

Fig 9 Connecting Adaptor Tool -- Typical
Fig. 8 Installing Adapter Tool And Pressure Gauge
NOTE: Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity
Test.
Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational.
After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid
gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure
that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the
electric fuel pump is activated, fuel pressure should immediately rise to specification.
Abnormally long periods of cranking to restart a hot engine that has been shut down for a short
period of time may be caused by: Fuel pressure bleeding past a fuel injector(s).
- Fuel pressure bleeding past the check valve in the fuel pump module.
1. Disconnect the fuel inlet line at fuel rail.
- On some engines, air cleaner housing removal may be necessary before fuel line disconnection.
2. Connect the appropriate Fuel Line Pressure Test Adapter Tool (number 6539, 6631, 6541 or
6923) between the disconnected fuel line and fuel rail
(Fig. 9) or (Fig. 10).
3. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test
port on the appropriate Adaptor Tool.
- The fittings on both tools must be in good condition and free from any small leaks before
performing the proceeding test.
4. Start engine and bring to normal operating temperature.

System Information > System Diagnosis > Fuel Pressure Leak Down Test > Page 2728
5. Observe test gauge. Normal operating pressure should be 339 kPa +/- 34 kPa (49.2 psi +/- 5
psi). 6. Shut engine off. 7. Pressure should not fall below 30 psi for five minutes. 8. If pressure falls
below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module,
or a fuel tube/line is leaking. 9. Again, start engine and bring to normal operating temperature.
10. Shut engine off. 11. Testing for fuel injector or fuel rail leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on
Adapter Tool.
- If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking.
12. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage:
- Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T"
on Adapter Tool.
- If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line.
- If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump
or filter/ regulator may be leaking.
NOTE: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A
slow loss of pressure usually indicates a defective check valve in the electric fuel pump.
The electric fuel pump is not serviced separately -- Replace the fuel pump module assembly. The
filter/ regulator may be replaced separately on certain applications. Refer to Fuel Filter/Fuel
Pressure Regulator Removal/installation for additional information.

Fuel Pressure Test Gauge
NOTE: Use this test in conjunction with the Fuel Pump Capacity Test, Fuel Pressure Leak Down
Test, fuel pump amperage test.
Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent
fuel flow hack into the tank and to maintain fuel supply line pressure (engine warm) when pump is
not operational. It is also used to keep the fuel supply line full of gasoline when pump is not
operational. After the vehicle has cooled down fuel pressure may drop to 0 psi (cold fluid
contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel
injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal
condition. When the electric fuel pump is activated, fuel pressure should immediately rise to
specification.
All fuel systems are equipped with a fuel tank module mounted, combination fuel filter/fuel pressure
regulator. The fuel pressure regulator is not controlled by engine vacuum.
WARNING: The fuel system is under constant fuel pressure even with the engine off. Before
disconnecting fuel line at fuel rail, this pressure must be released. Refer to the fuel system
pressure release procedure.
NOTE: To perform this test you will need to remove the engine cover.
1. Remove the protective cap at the fuel rail test port. Connect the 0-414 kPa (0-60 psi) fuel
pressure gauge (from gauge set 5069) to the test port
pressure fitting on the fuel rail.
2. Start and warm the engine and note pressure gauge reading. Fuel pressure should be 3.39 kPa
+/- 34 kPa (49.2 psi +/- 5 psi) at idle. 3. If engine runs but pressure is below 44.2 psi, check for a
kinked fuel supply line somewhere between fuel rail and fuel pump module. If line is not
kinked, replace fuel pump module assembly. Refer to Fuel Pump Removal/Installation.
4. If operating pressure is above 54.2 psi, electric fuel pump is OK, but fuel pressure regulator is
defective. Replace fuel filter/fuel pressure regulator.
Certain filter/regulators may be serviced separately and some require the replacement of the fuel
pump module assembly Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for more
information.

Fuel Gauge Sender: Description and Operation
DESCRIPTION
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a vanable resistor (track). The resistor track is used to
send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for
OBD II emission requirements.
OPERATION
For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the
sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and
arm move down. This increases the sending unit resistance causing the fuel gauge to read empty.
After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus
circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading.
For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the
sending unit to the PCM to indicate fuel level. The purpose of this feature is to prevent the OBD II
system from recording/setting false misfire and fuel system monitor trouble codes. The feature is
activated if the fuel level in the tank is less than approximately 15 percent of its rated capacity. If
equipped with a Leak Detection Pump (EVAP system monitor), this feature will also be activated if
the fuel level in the tank is more than approximately 85 percent of its rated capacity.

Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank > Fuel Gauge Sender >
Component Information > Technical Service Bulletins > Page 2758
Fuel Gauge Sender: Testing and Inspection
The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down,
electrical resistance will change. To test the gauge sending unit only, it must be removed from
vehicle. The unit is part of the fuel pump module. Refer to Fuel Pump Module Removal Installation
for procedures.
Measure the resistance across the sending unit terminals. With float in up position, resistance should be 20 ohms ± 6 ohms.
- With float in down position, resistance should be 220 ± 6 ohms.

- Terminal number 85 is grounded by the Powertrain Control Module (PCM).
TESTING
1. Remove relay before testing. 2. Using an ohmmeter, perform a resistance test between
terminals 85 and 86.
- Resistance value (ohms) should be 75 +/- 5 ohms for resistor equipped relays.
3. Connect the ohmmeter between terminals number 87A and 30.
- Continuity should be present at this time.
4. Connect the ohmmeter between terminals number 87 and 30.
- Continuity should not be present at this time.
5. Use a set of jumper wires (16 gauge or smaller).
- Connect one jumper wire between terminal number 85 (on the relay) to the ground side (-) of a 12
volt power source.
6. Attach the other jumper wire to the positive side (+) of a 12V power source.
- Do not connect this jumper wire to relay at this time.
CAUTION: Do not allow the ohmmeter to contact terminals 85 or 86 during these tests. Damage to
ohmmeter may result.
7. Attach the other jumper wire (12V +) to terminal number 86. This will activate the relay.
- Continuity should now be present between terminals number 87 and 30.
- Continuity should not be present between terminals number 87A and 30.
8. Disconnect jumper wires from relay and 12 volt power source.
If continuity or resistance tests did not pass, replace relay.

Camshaft Position Sensor: Description and Operation
SYSTEM OPERATION
The camshaft position sensor is located in the distributor on all engines.
The sensor contains a hall effect device called a sync signal generator to generate a fuel sync
signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The
pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction
with the crankshaft position sensor to differentiate between fuel injection and spark events. It is
also used to synchronize the fuel injectors with their respective cylinders.
When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following
occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync
signal of approximately 5 volts.
When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following
occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts.

Camshaft Position Sensor: Testing and Inspection
Camshaft Position Sensor - Typical
The camshaft position sensor is located in the distributor on all engines.
To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain
Diagnostics Procedures service. To test the sensor only, refer to the following:
For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector
from the distributor. Using small paper clips, insert them into the backside of the distributor wire
harness connector to make contact with the terminals. Be sure that the connector is not damaged
when inserting the paper clips. Attach voltmeter leads to these paper clips.
1. Remove engine cover. 2. Connect the positive (+) voltmeter lead into the sensor output wire.
This is at done the distributor wire harness connector. For wire identification. 3. Connect the
negative (-) voltmeter lead into the ground wire. For wire identification. 4. Set the voltmeter to the
15 Volt DC scale. 5. Remove distributor cap from distributor (two screws). Rotate (crank) the
engine until the distributor rotor is pointed towards the rear of vehicle.
The movable pulse ring should now be within the sensor pickup.
6. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 7. If voltage is
not present, check the voltmeter leads for a good connection. 8. If voltage is still not present, check
for voltage at the supply wire. For wire identification. 9. If 5 volts is not present at supply wire,
check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for
this
test.
10. If voltage is still not present, perform vehicle test using the DRB scan tool. 11. If voltage is
present at cavity A-17, but not at the supply wire:
a. Check continuity between the supply wire. This is checked between the distributor connector and
cavity A-17 at the PCM. If continuity is not
present, repair the harness as necessary
b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the
PCM. If continuity is not present, repair the
harness as necessary
c. Check for continuity between the ground circuit wire at the distributor connector and ground. If
continuity is not present, repair the harness as
necessary.
12. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle
should fluctuate between 0 and 5 volts while the
engine is cranking. This verifies that the camshaft position sensor in the distributor is operating
properly and a sync pulse signal is being generated. If sync pulse signal is not present,
replacement of the camshaft position sensor is necessary.

Crankshaft Position Sensor: Description and Operation
SYSTEM OPERATION
Sensor Operation
Engine speed and crankshaft position are provided through the crankshaft position sensor. The
sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM
interprets the sensor input to determine the crankshaft position. The PCM then uses this position,
along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
On this engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its
outer edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM. For each engine revolution, there are 8 pulses generated on V-8 engines.
The engine will not operate if the PCM does not receive a crankshaft position sensor input.

Distributor Cap: Testing and Inspection
Cap Inspection-External-Typical
Cap Inspection-Internal-Typical
Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for
cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the
inside (caused by condensation entering the cap through cracks). Replace any cap that displays
charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will
indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence
of mechanical interference with the rotor tip.

Ignition Rotor: Testing and Inspection
Rotor Inspection-Typical
Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip.
Also check for evidence of mechanical interference with the cap. Some charring is normal on the
end of the metal tip. The silicone-dielectric-varnish-compound applied to the rotor tip for radio
interference noise suppression, will appear charred. This is normal. Do not remove the charred
compound. Test the spring for insufficient tension. Replace a rotor that displays any of these
adverse conditions.

Ignition Cable: Description and Operation
SYSTEM OPERATION
Spark plug cables are sometimes referred to as secondary ignition wires. These cables transfer
electrical current from the ignition coil(8) and/or distributor, to individual spark plugs at each
cylinder. The resistive spark plug cables are of nonmetallic construction. The cables provide
suppression of radio frequency emissions from the ignition system.

Ignition Cable: Testing and Inspection
Heat Shields
Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and
spark plugs. Terminals should be fully seated. The insulators should be in good condition and
should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are
cracked or torn must be replaced.
Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the
cables dry. Check for brittle or cracked insulation.
Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable
boot and spark plug . These shields protect the spark plug boots from damage (due to intense
engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug
cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat
shield.
Testing
When testing secondary cables for damage with an oscilloscope, follow the instructions of the
equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as
follows:
CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during
testing. This may cause possible heat damage to the catalytic converter. Total test time must not
exceed ten minutes.
With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to
a good engine ground. If the cable and spark plug are in good condition, the engine rpm should
drop and the engine will run poorly If engine rpm does not drop, the cable and/or spark plug may
not be operating properly and should be replaced. Also check engine cylinder compression.
With the engine not running, connect one end of a test probe to a good ground. Start the engine
and run the other end of the test probe along the entire length of all spark plug cables. If cables are
cracked or punctured, there will be a noticeable spark jump from the damaged area to the test
probe. The cable running from the ignition coil to the distributor cap can be checked in the same
manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This
can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket.
Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped,
remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from
spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode
in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable
from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not
within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable.
Test all spark plug cables in this manner.
Spark Plug Cable Resistance MINIMUM = MAXIMUM 250 Ohms Per Inch = 1000 Ohms Per Inch
3000 Ohms Per Foot = 12,000 Ohms Per Foot
To test ignition coil-to-distributor cap cab]e, do not remove the cable from the cap. Connect
ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of
cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart,
remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable.
If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace
the cable. Inspect the ignition coil tower for cracks, burns or corrosion.

REMOVAL AND INSTALLATION
Cable Removal
CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap,
twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off
with a steady, even force.
Engine Firing Order
Install cables into the proper engine cylinder firing order.
When replacing the spark plug and coil cables, route the cables correctly and secure in the proper
retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It
could also cause cross ignition of the plugs or short circuit the cables to ground.
When installing new cables, make sure a positive connection is made. A snap should be felt when
a good connection is made between the plug cable and the distributor cap tower.

Ignition Coil: Description and Operation
SYSTEM OPERATION
Battery voltage is supplied to the ignition coil positive terminal from the Automatic Shutdown (ASD)
relay.
The Powertrain Control Module (PCM) opens and closes the ignition coil ground circuit for ignition
coil operation.
Base ignition timing is not adjustable on any engine. By controlling the coil ground circuit, the PCM
is able to set the base timing and adjust the ignition timing advance. This is done to meet changing
engine operating conditions.
The ignition coil is not oil filled. The windings are embedded in an epoxy compound. This provides
heat and vibration resistance that allows the ignition coil to be mounted on the engine.

Ignition Coil: Testing and Inspection Ignition Coil Test
To perform a complete test of the ignition coil and its circuitry, refer to the DRB scan tool. Also refer
to the appropriate Powertrain Diagnostics Procedures. To test the coil only, refer to the following:
Ignition Coil - Typical
The ignition coil is designed to operate without an external ballast resistor.
Ignition Coil Resistance
Coil Manufacturer = Diamond Primary resistance 21 - 27°C (70 - 80°F) = 0.97 - 1.18 Ohms
Secondary resistance 21 - 27°C (70 - 80°F) = 11,300 - 15,300 Ohms
Coil Manufacturer = Toydenso Primary resistance 21 - 27°C (70 - 80°F) = 0.95 - 1.20 Ohms
Secondary resistance 21 - 27°C (70 - 80°F) = 11,300 - 13,300 Ohms
Inspect the ignition coil for arcing. Test the coil according to coil tester manufacturer's instructions.
Test the coil primary and secondary resistance. Replace any coil that does not meet specifications.
Refer to the IGNITION COIL RESISTANCE chart.
If the ignition coil is being replaced, the secondary spark plug cable must also be checked. Replace
cable if it has been burned or damaged.
Arcing at the tower will carbonize the cable boot, which if it is connected to a new ignition coil, will
cause the coil to fail.
If the secondary coil cable shows any signs of damage, it should be replaced with a new cable and
new terminal. Carbon tracking on the old cable can cause arcing and the failure of a new ignition
coil.

Cable Removal
CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap,
twist the rubber boot slightly (112 turn) to break it loose. Grasp the boot (not the cable) and pull it
off with a steady, even force.
Checking For Spark - Typical
1. Disconnect the ignition coil secondary cable from center tower of tile distributor cap. Hold the
cable terminal approximately 12 mm (1/2 in.) from
a good engine ground.
WARNING: BE VERY CAREFUL WHEN THE ENGINE IS CRANKING. DO NOT PUT YOUR
HANDS NEAR THE PULLEYS, BELTS OR THE FAN. DO NOT WEAR LOOSE FITTING
CLOTHING.
2. Rotate (crank) the engine with the starter motor and observe the cable terminal for a steady arc.
If steady arcing does not occur, inspect tile
secondary coil cable. Refer to Spark Plug Cables. Also inspect the distributor cap and rotor for
cracks or burn marks. Repair as necessary. If steady arcing occurs, connect ignition coil cable to
the distributor cap.
3. Remove a cable from one spark plug. 4. Using insulated pliers, hold the cable terminal
approximately 12 mm (1/2 in.) from the engine cylinder head or block while rotating the engine
with the starter motor. Observe the spark plug cable terminal for an arc. If steady arcing occurs, it
can be expected that the ignition secondary system is operating correctly (If the ignition coil cable
is removed for this test, instead of a spark plug cable, the spark intensity will be much higher). If
steady arcing occurs at the spark plug cables, but the engine will not start, connect the DRB scan
tool. Refer to the appropriate Powertrain Diagnostic Procedures service.

Camshaft Position Sensor: Description and Operation
SYSTEM OPERATION
The camshaft position sensor is located in the distributor on all engines.
The sensor contains a hall effect device called a sync signal generator to generate a fuel sync
signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The
pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction
with the crankshaft position sensor to differentiate between fuel injection and spark events. It is
also used to synchronize the fuel injectors with their respective cylinders.
When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following
occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync
signal of approximately 5 volts.
When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following
occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts.

Camshaft Position Sensor: Testing and Inspection
Camshaft Position Sensor - Typical
The camshaft position sensor is located in the distributor on all engines.
To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain
Diagnostics Procedures service. To test the sensor only, refer to the following:
For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector
from the distributor. Using small paper clips, insert them into the backside of the distributor wire
harness connector to make contact with the terminals. Be sure that the connector is not damaged
when inserting the paper clips. Attach voltmeter leads to these paper clips.
1. Remove engine cover. 2. Connect the positive (+) voltmeter lead into the sensor output wire.
This is at done the distributor wire harness connector. For wire identification. 3. Connect the
negative (-) voltmeter lead into the ground wire. For wire identification. 4. Set the voltmeter to the
15 Volt DC scale. 5. Remove distributor cap from distributor (two screws). Rotate (crank) the
engine until the distributor rotor is pointed towards the rear of vehicle.
The movable pulse ring should now be within the sensor pickup.
6. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 7. If voltage is
not present, check the voltmeter leads for a good connection. 8. If voltage is still not present, check
for voltage at the supply wire. For wire identification. 9. If 5 volts is not present at supply wire,
check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for
this
test.
10. If voltage is still not present, perform vehicle test using the DRB scan tool. 11. If voltage is
present at cavity A-17, but not at the supply wire:
a. Check continuity between the supply wire. This is checked between the distributor connector and
cavity A-17 at the PCM. If continuity is not
present, repair the harness as necessary
b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the
PCM. If continuity is not present, repair the
harness as necessary
c. Check for continuity between the ground circuit wire at the distributor connector and ground. If
continuity is not present, repair the harness as
necessary.
12. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle
should fluctuate between 0 and 5 volts while the
engine is cranking. This verifies that the camshaft position sensor in the distributor is operating
properly and a sync pulse signal is being generated. If sync pulse signal is not present,
replacement of the camshaft position sensor is necessary.

Crankshaft Position Sensor: Description and Operation
SYSTEM OPERATION
Sensor Operation
Engine speed and crankshaft position are provided through the crankshaft position sensor. The
sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM
interprets the sensor input to determine the crankshaft position. The PCM then uses this position,
along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
On this engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its
outer edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM. For each engine revolution, there are 8 pulses generated on V-8 engines.
The engine will not operate if the PCM does not receive a crankshaft position sensor input.

Spark Plug: Description and Operation
SYSTEM OPERATION
All engines use resistor type spark plugs. Remove the spark plugs and examine them for burned
electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in
which they were removed from the engine. A single plug displaying an abnormal condition indicates
that a problem exists in the corresponding cylinder.
Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or
oil fouled.

Spark Plug: Testing and Inspection
Normal Operating
Spark Plug Cable Resistance
The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is
evident with most grades of commercial gasoline. There will not be evidence of electrode burning.
Gap growth will not average more than approximately 0.025 mm (0.001 in) per 1600 km (1000
miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the
electrodes filed, have the gap set and then be installed.
Some fuel refiners in several areas of the United States have introduced a manganese additive
(MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug
to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by
coolant in the combustion chamber. Spark plug performance is not affected by MMT deposits.
Cold Fouling/Carbon Fouling
Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are
basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking
valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be
caused by a clogged air cleaner element or repeated short operating times (short trips).
Wet Fouling Or Gas Fouling
A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings,
leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently
overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This
condition can usually be resolved by cleaning and reinstalling the fouled plugs.
Oil Or Ash Encrusted
Oil Or Ash Encrusted
If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of
oil entry into that particular combustion chamber.
Electrode Gap Bridging

Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information >
Specifications > Page 2947
Electrode Gap Bridging
Electrode gap bridging may be traced to loose deposits in the combustion chamber. These
deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is
suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between
electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be
cleaned using standard procedures.
Scavenger Deposits
Scavenger Deposit
Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is
a normal condition caused by chemical additives in certain fuels. These additives are designed to
change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that
accumulation on the ground electrode and shell area may be heavy, but the deposits are easily
removed. Spark plugs with scavenger deposits can be considered normal in condition and can be
cleaned using standard procedures.
Chipped Electrode Insulator
Chipped Electrode Insulator
A chipped electrode insulator usually results from bending the center electrode while adjusting the
spark plug electrode gap. Under certain conditions, severe detonation can also separate the
insulator from the center electrode. Spark plugs with this condition must be replaced.
Preignition Damage

Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information >
Specifications > Page 2948
Preignition Damage
Preignition damage is usually caused by excessive combustion chamber temperature. The center
electrode dissolves first and the ground electrode dissolves somewhat latter. Insulators appear
relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine.
Determine if ignition timing is over advanced or if other operating conditions are causing engine
overheating. (The heat range rating refers to the operating temperature of a particular type spark
plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon
the thickness and length of the center electrodes porcelain insulator.)
Spark Plug Overheating
Spark Plug Overheating
Overheating is indicated by a white or gray center electrode insulator that also appears blistered.
The increase in electrode gap will be considerably in excess of 0.001 inch per 1000 miles of
operation. This suggests that a plug with a cooler heat range rating should be used. Over
advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug
overheating.

Spark Plug: Service and Repair
Heat Shields
Spark plug cable heat shields are pressed into the cylinder head to surround each cable boot and
spark plug.
If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides
of shield for removal. Each shield is slotted to allow for compression and removal. To install the
shields, align shield to machined opening in cylinder head and tap into place with a block of wood.
PLUG REMOVAL 1. Remove engine cover. 2. Always remove spark plug or ignition coil cables by
grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady
motion. Never pull directly on the cable. Internal damage to cable will result,
3. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area
around the spark plug. This will help prevent
foreign material from entering the combustion chamber.
4. Remove the spark plug using a quality socket with a rubber or foam insert. 5. Inspect the spark
plug condition.
Plug Cleaning The plugs may be cleaned using commercially available spark plug cleaning
equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before
adjusting gap.
CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will
remain on the spark plug insulator arid will cause plug misfire.
Plug Gap Adjustment Check the spark plug gap with a gap gauge tool. If the gap is not correct,
adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center
electrode.
Spark Plug Gap V-8 Engines: 1.01 mm (.040 in).
PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder
head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be
damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in
a change in the spark plug gap or a cracked porcelain insulator.
when replacing the spark plug and ignition coil cables, route the cables correctly and secure them
in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce
ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground.
1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark
plugs to 35-41 N.m (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs.

NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC
TRANSMISSION.
SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission
when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning"
like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100
F.). The condition is caused by a resonance of the transmission regulator valve system.
Other items may cause regulator valve resonance, including air ingestion into the valve body or out
of specification parts. These two items may be the result a possible cracked pump housing, a torn
pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of
specification valve and/or valve body. You should remember these additional items / components
when you perform your diagnosis.
Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve
body or an entire automatic transmission was replaced with components manufactured after
August 1, 1995.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual,
verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble
Codes (DTC's) are present, record them on the repair order and repair as necessary before
proceeding further with this bulletin.
For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to
determine if it applies to this vehicle before attempting to complete the analysis or repairs
described in this bulletin.
In most instances, the sump temperature of vehicles exhibiting transmission regulator valve
resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to
remain parked in a cool place overnight. Then perform the following steps:
1. Set the vehicle parking brake.
2. Start the engine (make certain windows are closed, to eliminate outside noise).
3. With brakes applied, place the transmission selector lever in reverse.
4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to
normal operating temperature (180 - 210 degrees F).
5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

Description and Operation
Overdrive Indicator Lamp: Description and Operation
SYSTEM OPERATION
The overdrive-off indicator lamp gives the driver an indication that the automatic transmission
overdrive has been locked out. The lamp is controlled by the Powertrain Control Module (PCM) on
a hard wired circuit to instrument cluster.
The PCM receives an input from the momentary overdrive lockout switch, which is located on the
end of the automatic transmission gearshift selector lever. The PCM uses the overdrive lockout
switch input, along with numerous other sensor inputs and its internal programming to decide
whether the over-drive-off indicator lamp should be on or off. The PCM then turns the lamp on or
off by controlling the ground path for the lamp control circuit.

Overdrive Indicator Lamp: Testing and Inspection
The diagnosis found here addresses an inoperative overdrive-off indicator lamp condition. If the
overdrive-off indicator lamp comes on and stays on with the engine running, refer to the proper
Diagnostic Procedures for diagnosis of the Powertrain Control Module (PCM) and the transmission
control system circuits.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
1. Check the fuse in the junction block. If OK, go to Step 3. If not OK, repair the shorted circuit or
component as required and replace the faulty fuse. 2. Turn the ignition switch to the On position.
Check for battery voltage at the fuse in the junction block. If OK, go to Step 4. If not OK, repair the
open circuit to the ignition switch as required.
3. Disconnect and isolate the battery negative cable. Unplug the gray PCM wire harness connector.
Install a jumper wire between the overdrive lamp
driver circuit cavity of the gray PCM wire harness connector and a good ground. Connect the
battery negative cable. Turn the ignition switch to the On position. The overdrive-off indicator lamp
should light. Remove the jumper wire and the lamp should turn off. If OK, refer to the proper
Diagnostic Procedures for diagnosis of the Powertrain Control Module (PCM) and the transmission
control system circuits. If not OK, go to Step 5.
4. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable.
Remove the instrument cluster. Check for continuity
between the overdrive lamp driver circuit cavity of the gray PCM wire harness connector and a
good ground. There should be no continuity. If OK, go to Step 6. If not OK, repair the short circuit
as required.
5. Check for continuity between the overdrive lamp driver circuit cavities of the gray PCM wire
harness connector and the instrument cluster wire
harness connector (connector A). There should be continuity. If OK, replace the faulty bulb. If not

SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too
High
OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain
Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and
99Cal14).
MODELS:
**1996** - 1999 (AB) Ram Van
**1996** - 1999 (AN) Dakota
**1996** - 1999 (BR/BE) Ram Truck
1998 - 1999 (DN) Durango
**1997** - 1999 (TJ) Wrangler
**1996** 1999 (XJ) Cherokee
**1996** - 1998 (ZJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC
TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX).
SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble
Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle
operator may experience slower than normal vehicle accelerations because the transmission may
have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode
may last until the vehicle owner cycles the ignition key. The technician may not detect a problem
with the automatic transmission during a diagnostic test or test drive.
The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the
result of a new valve body machining process, which entered into production January 1, 1998. This
condition will occur most often with vehicles that were built between January 1, 1998 and
December 18, 1998.
Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the
transmission assembly is replaced with components built after January 1, 1998.
DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB
III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission
systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record
them on the repair order and repair as necessary before proceeding further with this bulletin. If no
DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF

SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too
High
OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain
Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and
99Cal14).
MODELS:
**1996** - 1999 (AB) Ram Van
**1996** - 1999 (AN) Dakota
**1996** - 1999 (BR/BE) Ram Truck
1998 - 1999 (DN) Durango
**1997** - 1999 (TJ) Wrangler
**1996** 1999 (XJ) Cherokee
**1996** - 1998 (ZJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC
TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX).
SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble
Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle
operator may experience slower than normal vehicle accelerations because the transmission may
have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode
may last until the vehicle owner cycles the ignition key. The technician may not detect a problem
with the automatic transmission during a diagnostic test or test drive.
The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the
result of a new valve body machining process, which entered into production January 1, 1998. This
condition will occur most often with vehicles that were built between January 1, 1998 and
December 18, 1998.
Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the
transmission assembly is replaced with components built after January 1, 1998.
DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB
III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission
systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record
them on the repair order and repair as necessary before proceeding further with this bulletin. If no
DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF
THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION
LEVEL. USE THE FLASH PROCEDURE TO UPDATE REPLACED CONTROLLERS AS
NECESSARY.

NOTE:
THIS INFORMATION APPLIES TO VEHICLES BUILT BEFORE JAN 16, 1998 MDH (0116XX)
EQUIPPED WITH GASOLINE ENGINES AND A 42/44/46 OR 47RE TRANSMISSION.
SYMPTOM/CONDITION:
Some vehicles may experience bucking during wide open throttle (WOT) acceleration. The bucking
occurs at approximately 5300 RPM. This condition may be caused by reaching the high RPM fuel
shut off rev limit before the transmission can shift into the next higher gear and is most likely to
occur with high electrical loads (high beams on, heated back lite, heated seats, radio, HVAC blower
on MAX etc.). During high current demands, the generator may emit electrical noise that can affect
the transmission governor pressure sensor output. If this occurs, the transmission may not shift
properly to the next higher gear under (WOT) acceleration conditions and therefore reach the fuel
shut off rev limiter. This may be seen most often between the 2-3 shift but can also be experienced
between the 1-2 shift.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual,
verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes
(DTC's) are present, record them on the repair order and repair as necessary before proceeding
further with this bulletin.
NOTE:
ONLY PERFORM THE FOLLOWING PROCEDURE SAFELY ON A HIGHWAY OR ROAD
OBEYING ALL POSTED SPEED LIMITS AND LAWS.
Attempt to duplicate the condition by switching on all accessory loads and driving the vehicle with
WOT accelerations through a shift sequence to see if the engine will reach the fuel shut off rev
limiter before the 2-3 or 1-2 shift is made.
If the bucking condition is experienced at approximately 5300 RPM before making the appropriate
upshifts, switch off all electrical loads and repeat the procedure. Repeat the procedure with the
electrical loads on and off a second time. If the bucking occurs with the electrical loads on and
does not occur with the loads off, perform the Repair Procedure.
PARTS REQUIRED:

TRANSMISSION SPEED SENSOR
Transmission Output Speed Sensor
The speed sensor is located in the overdrive gear case. The sensor is positioned over the park
gear and monitors transmission output shaft rotating speed. Speed sensor signals are triggered by
the park gear lugs as they rotate past the sensor pickup face. Input signals from the sensor are
sent to the transmission control module for processing. The rear wheel speed sensor also serves
as a backup for the transmission speed sensor. Signals from this sensor are shared with the
powertrain control module. See: Brakes and Traction Control/Antilock Brakes / Traction Control

Owner Letter
EMISSIONS RECALL TO REPROGRAM YOUR VEHICLE'S POWERTRAIN CONTROL MODULE
Dear DaimlerChrysler Vehicle Owner:
DaimlerChrysler has determined that some 1998 Dodge Dakota, Durango, Ram Van/Wagon, Ram
Truck, and Jeep(R) Grand Cherokee vehicles, equipped with a V-8 or V-10 engine, may be in
violation of California Emissions Regulations.
The problem is...
The On-Board Diagnostic (OBD) system on your vehicle (identified on the enclosed form) may not
detect evaporative emissions purge system malfunctions as required by California Emissions
Regulations. As a result, the OBD system on your vehicle may not illuminate the "Check Engine"
light if the evaporative emissions purge system malfunctions. This could cause your vehicle to emit
hydrocarbon levels above the limits that were established to protect the public health from the
dangers of air pollution.
Hydrocarbons (unburned fuel) combined with oxides of nitrogen, in the presence of sunlight, can
cause the formation of ozone. These pollutants are the primary components of smog.
What DaimlerChrysler and your dealer will do...
DaimlerChrysler will repair your vehicle free of charge (parts and labor). To do this, your dealer will
reprogram your vehicle's powertrain control module. The work will take about 1/2 hour to complete.
However, additional time may be necessary depending on how dealer appointments are scheduled
and processed.
What you must do...
^ Simply contact your dealer right away to schedule a service appointment.
^ Bring the enclosed Owner Notification form with you to your dealer. It identifies the required
service to the dealer.
If you live in California and don't get this done...
The State of California requires the completion of emission recall repairs prior to vehicle
registration renewal. In addition, the State requires that every vehicle must pass an emission test
(SMOG Check) every two years and before it is sold. Without the free service we are providing,
your vehicle may be more likely to fail this test and require that you make costly repairs.
How the state knows that the recall has been performed...
State of California regulations require DaimlerChrysler to provide the Department of Motor Vehicles
with a record of all vehicles that have not had the recall service performed. If you live in the state of
California and your vehicle is not on this list, the state will know that the recall has been completed.
Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the
recall service is completed. Be sure to save this form since the California Department of Motor
Vehicles may require that you supply it as proof of recall completion.

NOTE:
THIS INFORMATION APPLIES TO NATURALLY ASPIRATED (NON-TURBO) GASOLINE
ENGINES.
DISCUSSION:
Some states that require I/M inspections are beginning to include OBD II "CARB" Readiness as a
prerequisite to an I/M test. OBD Readiness tells an I/M station if the OBD II systems have run their
self test. Owners, in those states that use OBD Readiness, may be denied an I/M test if one or
more of the Readiness monitors read "NO" or in other words the OBD II monitors have not run their
tests.
It is important to understand that the MIL will not be illuminated because OBD Readiness reads
"NO". MIL illumination happens when an actual malfunction or failure of a monitored emissions
system occurs. It is possible to have MIL illumination for a detected failure while at the same time
having a "NO" for an OBO Readiness monitor.
NOTE:
MIL ILLUMINATION INDICATES ADDITIONAL PROBLEMS WITH THE VEHICLE. FURTHER
DIAGNOSIS AND REPAIR WILL BE REQUIRED BEFORE PROCEEDING FURTHER WITH THIS
BULLETIN.
OBD Readiness that reads "NO" can be caused by the following: PCM reprogramming, PCM
replacement, fault code erasure, battery disconnects and/or replacement. If any of the above items
occur before an I/M test, a good chance exists that one or more of the monitors will read "NO" for
OBD Readiness.
Some customers may be directed back to their dealers for assistance when an I/M test station has
not allowed an I/M test due to Readiness status. The following procedures will help technicians
efficiently run the Readiness tests so an owner can have their I/M test completed.

FAILURE CODE: XX - Service Adjustment
Repair Procedure
This bulletin involves operating the vehicle under specific parameters to run or complete the OBD
monitors. The number of monitors applicable to a vehicle will vary by type of vehicle and emissions
application. In addition, the parameters to run each monitor will vary.
Preliminary Checks
1. Perform a MIL bulb check by switching the ignition key "ON" (engine off). The MIL will illuminate
as a bulb check. If the MIL does not illuminate, repair the bulb or bulb circuit.
2. Connect a DRB III(R) to the vehicle. Select DRB III(R) standalone, current model year
diagnostics, engine, DTC's and related functions, read DTC's.
3. Verity that no emission related DTC's are present and that the MIL is not illuminated with the
engine running.
NOTE:
EMISSION RELATED DTC'S AND MIL ILLUMINATION MAY PREVENT OTHER OBD MONITORS
FROM RUNNING. DTC'S THAT ILLUMINATE THE MIL MUST BE REPAIRED BEFORE
ATTEMPTING TO RUN THE MONITORS.
OBD "CARB" Readiness Check
1. With the DRB III(R) select engine, OBD II monitors, CARB Readiness Status.
2. Read the monitor status. "YES" tells you that monitor has run and is ready for an I/M test, "NO"
tells you that the monitor must be run. If all monitors listed read "YES", the vehicle can be returned
to the customer for completion of their I/M test. Only monitors that read "NO" must be run to read
"YES".
NOTE:
THE MONITORS LISTED IN THE OBD "CARB" READINESS SCREEN ARE THE ONLY ONES
APPLICABLE FOR THE VEHICLE BEING WORKED ON.
The vehicle must be operated in various conditions (speed, temperature, etc.) for the monitors to
run. Each monitor includes a pre-test and monitor test that can be viewed on the DRB III(R). The
pre-test/monitor test screen lists all the preliminary parameters that must be met along with the
running parameters for that specific monitor to run. An example of one screen is shown in Figure 1.

Readiness Monitor Information > Page 3077
NOTE:
1997 AND PREVIOUS MODEL VEHICLES WILL HAVE A DIFFERENT LOOKING SCREEN.
PRESS THE F1 KEY TO OBTAIN MONITOR RUN CONDITIONS. THE WAY IN WHICH THE
MONITORS RUN WILL BE SIMILAR.
The following explains how to interpret each section of the screen:
PRE-TEST REQUIREMENTS
The pre-test requirements include all the operating parameters that must be met before the actual
test can run. The vehicle must be operated until each item within the pre-test section are fulfilled.
LOW VALUE/HIGH VALUE/BAR GRAPH
The low value/high value provides the minimum and maximum operating conditions for each item
(ie ECT Range must be between 170° and 260° F in Figure 1). The bar graph will begin to fill when
the lowest value required for each item is met. This provides a visual indication that the parameters
are being met. The vehicle should be driven until most of each pre-test bar graph is filled.
MONITOR REQUIREMENTS
Once all pre-test requirements are met, the vehicle must be brought within the parameters listed in
the monitor requirements section for the monitors to begin running. As the monitor begins to run,
the DRB III(R) will begin to beep. This is an audible indication that the test is in progress. If vehicle
operation falls outside any of the parameters, the beeping will stop. If this occurs, the technician
must determine if the pre-test requirements or the monitor requirements have fallen outside the
window for the test and the vehicle must be driven accordingly for the test to restart. When the
monitor completes its test, the DRB III(R) will beep 3 consecutive times.
NOTE:
THE PURGE FLOW PRE-TEST SCREEN WILL LOOK DIFFERENT THAN THE REST OF THE
PRE-TEST/MONITOR SCREENS. PRESS THE F1 KEY ON THE DRB III(R) TO SEE A SIMILAR
SCREEN FOR THIS MONITOR.
MONITOR RUN PROCESS
The following will provide the most efficient order along with tips to help run through the monitor
tests quickly. The monitors listed include all possible monitors for either Front Wheel Drive or Rear
Wheel Drive vehicles. The vehicle being worked on may have fewer monitors than the maximum
available. Only those listed on the DRB III(R) are applicable for the vehicle being worked on. The
only monitors that will require attention are those that read "NO" under the OBD "CARB"
Readiness Status screen.
Front Wheel Drive
1. Evaporative Leak Detection Monitor - This test will require a cold start (possibly an overnight
soak either indoors or out depending on conditions). The ambient (outside) temperature must be
between 4° and 32° C (40° and 90° F) with the engine coolant temperature within 6° C (10 ° F) of
ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen
on the DRB III(R) to determine the remaining requirements.
2. Catalyst Monitor - The vehicle must be driven at highway speeds for the time listed in the
pre-test screen. If the vehicle is equipped with a manual transaxle, use fourth gear to help meet the
requirements.
3. EGR Monitor - It is necessary to maintain TPS, MAP, and RPM ranges listed in the pre-test
screen for this test to complete.
4. O2 Sensor Monitor - The vehicle must be driven and brought to a stop for the time listed in the
pre-test screen. Automatic transaxle vehicles must be left in drive during the stop period.
5. Purge Monitor - To see a similar screen format as listed in Figure 1, press the F1 key on the
DRB III(R) while in the Purge Flow Pre-Test screen. The purge free (PF) cells must update and the
monitor will attempt to run on every other throttle closure. Automatic transaxle vehicles must be left
in drive for the test to run. If all parameters are met and the test still will not run, place your foot on
the brake, open the throttle to 1/4 and then quickly close the throttle. This should allow the PF cells
to update.
6. O2 Sensor Heater Monitor - The open throttle time for the O2 Heater pre-test must be exceeded.
This monitor will run after the ignition key is switched "Off". After the DRB III(R) switches to No
Response (approximately 3 minutes) turn the ignition key "On" and check the O2 Sensor Heater
monitor status. It should have switched to "YES". All other monitors should be completed before
running this test.
Rear Wheel Drive
1. O2 Sensor Heater Monitor - This test will require a cold start (possibly an overnight soak either
indoors or outdoors depending on conditions). The ambient (outside) temperature must be between
18° and 38° C (0° and 100° F with the engine coolant temperature within 6° C (10° F) of
ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen
on the DRB III(R) to determine the remaining

2. Evaporative Leak Detection Monitor - This test will require a cold start (possibly an overnight
soak either indoors or outdoors depending on conditions). The ambient (outside) temperature must
be between 4° and 32° C (40° and 90° F) with the engine coolant temperature within 6° C (10 ° F)
of ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test
screen on the DRB III(R) to determine the remaining requirements.
3. Catalyst Monitor - The vehicle must be driven at highway speeds for the time listed in the
pre-test screen. If the vehicle is equipped with a manual transmission, use 4th gear to help meet
the requirements.
4. O2 Sensor Monitor - The vehicle must be driven and brought to a stop for the time listed in the
pre-test screen. Automatic transmission vehicles must be left in drive during the stop period.
5. Purge Monitor - To see a similar screen format as listed in Figure 1, press the F1 key on the
DRB III(R) while in the Purge Flow Pre-Test screen. The purge free (PF) cells must update and the
monitor will attempt to run on every other throttle closure. Automatic transmission vehicles must be
left in drive for the test to run. If all parameters are met and the test will still not run, place your foot
on the brake, open the throttle to 1/4 and then quickly close the throttle. This should allow the PF
cells to update.

Repair Procedure
This bulletin involves installing a cold weather by-pass kit to the transmission cooler circuit,
selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software
(calibration changes for 1996 models only), and using the DRB III to selectively turn off the
overdrive inhibitor feature for all applications.
NOTE:
IT IS ESSENTIAL THAT THE TRANSMISSION COOLER BYPASS KIT BE INSTALLED PRIOR
TO DISABLING THE INHIBITOR FEATURE. TRANSMISSION DAMAGE MAY OCCUR IF THE
BYPASS KIT IS NOT INSTALLED.
NOTE:
EVEN WITH BYPASS KIT INSTALLATION AND THE INHIBITOR FEATURE TURNED OFF, 4TH
GEAR WILL BE INHIBITED UNTIL THE OIL SUMP TEMPERATURE REACHES 0 C (30 F). THIS
MAY TAKE SEVERAL MINUTES.
Bypass Kit Installation
1. Record all radio pre-sets and disconnect the negative battery cable.
2. Raise the vehicle for access to the transmission housing. The bypass assembly will be
connected to the existing transmission lines and mounted to the transmission housing by means of
a bypass adapter.
3. During this installation procedure, some transmission fluid will be lost when the transmission
cooler lines are cut (allowing bypass assembly installation). Take proper precautions and check
transmission fluid fill level upon completing the installation.
4. It the cold weather bypass kit has provision for an in-line temperature sensor, the threaded
"therm-o-well" (in the pressure "P" line of the kit) must be plugged with either the temperature
sensor from the existing transmission line or the standard pipe plug provided. Consequently, if the
vehicle being serviced is equipped with a temperature sensor (i.e., heavy duty BR truck), remove
the temperature sensor from the existing line by un-threading and install it in the "pressure" line
provided with the kit. Use Mopar Thread Sealant, p/n 04318044, to ensure a leak free seal.
5. Disconnect the pressure and return lines from the transmission housing fittings.
6. Remove and discard the fittings from the transmission housing.
7. Apply Mopar Thread Sealant, p/n 04318044, to the threaded bypass adapter (# 2 Figure 1).
8. Install the threaded bypass adapter securely into the front pressure port of the transmission
housing and torque to 17.6 Nm (13 ft. lbs.).
9. Make sure the snap ring and O-ring are properly installed in their respective grooves on the nose
of the bypass assembly block. Lubricate the O-ring with ATF.
10. Position the bypass assembly block such that the return port fitting "R" is pointed directly up
and the two other fittings are pointed forward.
11. Firmly press the male nose of the bypass assembly into the female body of the threaded
bypass adapter until it snaps into place. After snapping into place, the bypass assembly is
permanently attached to the adapter.
NOTE:
THE BYPASS ASSEMBLY CAN ROTATE INSIDE THE ADAPTER, AND REMOVAL OF THE
BLOCK FROM THE TRANSMISSION HOUSING (IF REQUIRED) CAN BE ACCOMPLISHED BY
UN-THREADING THE ADAPTER.
CAUTION:
IF FLUSHING THE BYPASS ASSEMBLY IS REQUIRED, IT MUST BE REMOVED FROM THE
TRANSMISSION HOUSING AND FORWARD FLUSHED ONLY. FAILING TO REMOVE THE
VALVE AND REVERSE FLUSHING WILL RESULT IN TRANSMISSION FAILURE BY PLUGGING
THE BYPASS VALVES INTERNAL ORIFICE AND DRAIN BACK VALVE.
12. Apply Mopar Thread Sealant, p/n 04318044, to the threaded end (transmission housing end) of
the compression fitting.
13. Install the threaded compression fitting securely into the rear return port of the transmission
housing and torque to 17.6 Nm (13 ft. lbs.).

14. Using a small tubing cutter, cut the existing pressure line at approximately 120 mm (5 in.) from
the transmission housing end. Repeat the procedure for the existing return line.
CAUTION:
AFTER CUTTING THE PRESSURE LINE, MARK IT WITH A PIECE OF TAPE FOR
IDENTIFICATION.
15. Identify the proper return line ("R" line) by using the marked labels attached to the tubes.
16. Connect the "R" line to the bypass assembly block and the rearward return port of the
transmission housing. Tighten the compression fitting finger tight, and then wrench tighten it an
additional 1/2 turn. Tighten the inverted flare nut to 6.78 Nm (60 in. lbs.).
17. Select the appropriate "RR" and "P" tubes for the application. Mixing or matching may be
required to provide the best routing for your

application.
18. Loosely connect the pressure line "P" to the pressure port fitting "P" on the bypass assembly
block.
19. Loosely connect the radiator return line, "RR" to the "RR" port fitting, on the bypass assembly
block.
NOTE:
DURING THE INSTALLATION OF THE "P" AND "RR" LINES, THE ORDER MAY BE REVERSED
TO AID IN THE ASSEMBLY PROCESS.
NOTE:
ON 5.2L ZJ MODELS, THE THROTTLE VALVE CABLE AND BRACKET MAY REQUIRE
REMOVAL FOR BYPASS TUBE CLEARANCE. ONCE THE TUBES ARE INSTALLED LOOSELY,
INSTALL THE BRACKET AND THROTTLE VALVE CABLE. MAKE ANY ADJUSTMENTS FOR
CLEARANCE AND TIGHTEN THE BYPASS TUBES AND BRACKET ASSEMBLY.
20. Make sure that the existing return line is properly re-attached to the hanger bracket and lay the
new return line, "RR", beside it.
21. Install the hose bracket (# 12 in Figure 1) required for the overhead line application. The
bracket will replace the existing bracket at the starter mount location. It may require slight
modification to provide the best clearance from the exhaust system.
22. Attach clamp (# 11 in Figure 1) and the rubber hose to the "RR" tube to determine the
approximate rubber hose routing. For connection to the existing return line, the line may be cut
again to provide optimum line routing.
CAUTION:
WHEN ROUTING THE TUBING AND HOSE BE AWARE OF POTENTIAL MOVING
COMPONENT INTERFERENCES, SUCH AS THE PROPELLER SHAFT, SHIFT LINKAGE IN ALL
POSITIONS, TV CABLE, TV RETURN SPRING, AND TV LINKAGE. BE AWARE OF THE
EXHAUST SYSTEM, ALL ROUTINGS SHOULD MAINTAIN AT LEAST ONE INCH OF
CLEARANCE FROM THE EXHAUST SYSTEM.
23. Cut the rubber hose so that it has sufficient length to be attached to the existing return line.
24. Loosely connect a nut (# 7 in Figure 1), a compression sleeve (# 8 in Figure 1), and a hose
fitting (# 10 in Figure 1) to the existing return line.
25. Using a clamp (# 11 in Figure 1), install the rubber hose onto the hose fitting (# 10 in Figure 1).
26. Evaluate the line routing to ensure moving components and exhaust will not interfere with the
new lines. Make modifications as necessary to provide the best routing.
27. Disconnect the "RR" tube from the Bypass Block for access to the "P" port on the block
assembly.
28. Attach a clamp and the rubber hose to the "P" tube and determine the approximate rubber hose
routing. For connection to the existing pressure line, the line may be cut again to provide optimum
line routing.
CAUTION:
WHEN ROUTING THE TUBING AND HOSE BE AWARE OF POTENTIAL MOVING
COMPONENT INTERFERENCES, SUCH AS THE PROPELLER SHAFT, SHIFT LINKAGE IN ALL
POSITIONS, TV CABLE, TV RETURN SPRING, AND TV LINKAGE. BE AWARE OF THE
EXHAUST SYSTEM, ALL ROUTINGS SHOULD MAINTAIN AT LEAST ONE INCH OF
CLEARANCE FROM THE EXHAUST SYSTEM.
29. Cut the rubber hose so that it has sufficient length to be attached to the existing pressure line.
30. Loosely connect a nut (# 7 in Figure 1), a compression sleeve (# 8 in Figure 1), and a hose
fitting (# 10 in Figure 1) to the existing pressure line.
31. Using a clamp (# 11 in Figure 1), install the rubber hose onto the hose fitting (# 10 in Figure 1).
32. Evaluate the line routing to ensure moving components and exhaust will not interfere with the
new lines. Use tie straps and rubber bumpers on the hose to protect the hose from metal surfaces
that may cause chaffing.
33. Torque both clamps, the compression fitting (finger tight, then wrench tighten 1/2 turn), and the
inverted flare nut to 6.78 Nm (60 in. lbs.) on the "P" line.
34. Connect the "RR" ling and torque both clamps, the compression fitting (finger tight, then wrench
tighten 1/2 turn), and the inverted flare nut to 6.78 Nm (60 in. lbs.) on the "P" line.
35. Re-check to ensure that all connections have been securely tightened and there is sufficient
clearance around the exhaust system.

DISCUSSION:
NOTE:
Many of the reasons a flash reprogramming procedure may not complete are documented in this
service bulletin, but if you are constantly having issues performing the flash reprogramming
procedure using a specific DRBIII(R), it is suggested you send the DRBIII(R) in question to
SPX/Miller Special Tools for service.
Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment
may lock up or become disconnected during the procedure. Flash Reprogramming is a "CRITICAL
PROCESS"; an error may result in a no-start/failed control module. Most modules, encountering an
interruption or failure while reprogramming, are recoverable; a recoverable module is not covered
under the provisions of the warranty.
This service bulletin covers items that may cause this condition, a process to restart the flash
procedure, and miscellaneous information that will help prevent needless replacement of control
modules.
GENERAL: Flash Reprogramming is only authorized by a specific SERVICE BULLETIN, or
RECALL.
Review the entire Service Bulletin/Recall prior to performing a flash reprogramming update. Often
other parts may need to be serviced, replaced, or tested, prior to flash reprogramming, and ARE
REQUIRED as part of completing the Service Bulletin/Recall.
When flashing a Powertrain Control Module (PCM) or Transmission Control Module (TCM) there
are other legal requirements with labeling issues that are included in those service bulletins.
Other non-emission related modules, such as instrument clusters and Body Control Modules
(BCMs) do not require labels.
FLASH REPROGRAMMING SEQUENCE OF EVENTS
The process of flash reprogramming is similar to flashing the BIOS on a Personal Computer.
Interruptions, voltage problems, and a variety of other outside interactions can potentially interfere
with the process. This document seeks to provide information to minimize problems associated
with vehicle control module flash reprogramming. The description that follows is for most PCMs
and some TCMs. Other modules use different initiation procedures.
The process starts by selecting an update from the TechCONNECT Client or ISIS and then
"loading" that update into the DRBIII(R). Once the flash reprogramming update is loaded into the
DRBIII(R), and before the flash reprogramming begins, the DRBIII(R) verifies that the update
loaded from the TechCONNECT Client or ISIS is the proper update for the module. This is done
using part number supersedence. This verification occurs only if an update is required, available
(on the TechCONNECT Client or ISIS) and has been selected for programming.
^ The module is then placed into "Boot Strap" programming mode by the DRBIII(R). This module
mode gives the DRBIII(R) permission and the ability to proceed with the flash reprogramming
session.
^ Next, the current part number, which resides in the module's flash memory, is stored in a "Safe
Memory" location within the module. This memory location is not affected by flash memory erasure
and reprogramming, which are to follow.
^ Once the part number is safely stored, the flash memory in the control module is erased. From
this point forward any interruption in the flash process,

will result in a Non-Responsive module (NR). A NR module is a module that is either partially
erased or partially programmed.
^ After erasure, the actual reprogramming procedure starts, and the update software is
programmed into the flash memory within the module.
^ When reprogramming is completed, the flash memory is verified through an internal process in
the DRBIII(R) using a "Check Sum". This value is compared against another value that represents
what should be in memory and when matched, verifies successful reprogramming.
^ Next, a DRBIII(R) prompt is displayed instructing that the ignition switch be turned OFF. The
module exits the "Boot Strap" mode when the switch is turned off.
^ After a slight pause, the DRBIII(R) will prompt for the ignition switch to be turned ON. The
DRBIII(R) then reads the new part number in flash memory (along with a new computer program
the new part number is placed into the module's memory). If the new part number matches the
expected part number, the flash reprogramming session has completed successfully.
SOFTWARE VERSIONS MUST BE CURRENT
Before attempting a flash reprogramming session using the TechCONNECT Client, make sure you
have the most current DRBIII(R) software installed.
To verify whether your DRBIII(R) software is current, check the upper right-hand corner of the
TechCONNECT Client screen for DRBIII(R) Available Version, DRBIII(R) Current Version.
Often, because of multiple DRBIII(R)s in the shop, not all will get updated on a timely manner. The
installed DRBIII(R) software version can generally be found at the bottom center of most screens.
Alternately the version can be checked by pressing 6, 2, 5 from the DRBIII(R) Main Menu and
comparing it to what is available from a current TechCONNECT Client as described above.
If the TechCONNECT Client is current and the DRBIII(R) is not, it may be due to the fact that the
TechCONNECT Client does not force DRBIII(R) updates for "minor" revisions. Changes and new
support are added to the Vehicle Flash application on "minor" revisions on a regular basis. This is
why your TechCONNECT Client and DRBIII(R) must have the LATEST software revisions
installed.
DO NOT PASS on the option for updating to a "minor" revision!
Major updates require the DRBIII(R) to be updated prior to allowing any flash programming.
DRBIII(R) CABLES
A NEW DRBIII(R) cable was released as an Essential Service Tool! CH7000A - 8 ft.
Cable, DRBIII(R) to OBDII (J1962) DLC Connector.
CH7000A is the required cable for ALL flash reprogramming. The older CH7000 cable can be used
for diagnostics ONLY. One (1) cable was shipped to all dealerships. Easily identified, the correct
cable has a RED connector, which plugs into the DRBIII(R).
The cable modification enhances the DRBIII(R) communication capabilities when dealing with the
flash requirements of certain controllers/ECUs affected in part by the recent changes in DLC
connector configurations.
The new cable is required for ALL flash reprogramming sessions, and can be used wherever the
previous CH700017001 cables were used.
While not recommended for flash reprogramming usage, if you require a longer cable, there is also
a 12-foot cable released under pin CH7001A
The production of the previous CH700017001 cables has ceased. All orders placed will be
superseded to part number CH7000A/CH7001A.

NOTE:
Consider all cables wear items. Always inspect for worn, damaged cables, connectors that are
damaged or do not lock securely, and all mating connections including checking for corrosion on
the pins. REPLACE ALL suspect cables. Do not use worn or damaged cables when flash
reprogramming.
Failure to use the new cable or to use a damaged cable often results in failed flash reprogramming
sessions.
The 2 door Sebring, Stratus, and Avenger coupes (supplied by MMC) generally use the CH7O1O
cable (Pre-OBDII MMC vehicles will use the CH7005 cable).
TechCONNECT CABLE (GPIB)
Replace any suspect GPIB cable.
The GPIB cable provides the connection between TechCONNECT Client and the DRBIII(R).
This cable is used by the TechCONNECT Client for vehicle part number reads and to send update
files to the DRBIII(R).
Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If
this cable becomes disconnected during a flash session, you may have to reload the update file
that you selected on the TechCONNECT Client.
TROUBLESHOOTING CONNECTIVITY OF THE DRBIII(R) UNIT TO THE TechCONNECT
APPLICATION.
1. Turn-on the power to the DRBIII(R) unit.
2. Select option 2 "Connect to TechCONNECT" and press Enter.
3. Attach the male mini D-shell amphenol GPIB connector of the new DRBIII(R) cable (part number
CH7035B) to the DRBIII(R) unit.
4. Insure that the larger female D-shell amphenol GPIB connector of the new DRBIII(R) cable is
properly attached to the male D-shell amphenol GPIB connector on the GPIB-USB-B protocol
converter, (part number CHGPIB-B).
5. Attach the USB cable from the GPIB-USB-B protocol converter to one of the USB ports on the
rear panel of the client CPU.
6. When the cable is attached to the USB port of the CPU for the first time, Windows 2000 will
detect the device and install software for it. Please wait for 25-30 seconds to complete the
installation.

ISIS NULL MODEM CABLE
Replace any suspect null modem cables.
International (ISIS), a PC-based CD program similar to TechCONNECT Client uses a null modem
cable for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for
loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes
disconnected during a flash download session, you will have to reload the update file or files.
GENERAL NOTES FOR CABLES AND VEHICLE CONNECTIONS
Consider ALL cables to be wear items.
Many successful dealers have dedicated cables devoted to "Flash ONLY".
Always have spare CH7000A, CH7010 and CH2002 GPIB or null modem cables available.
Inspect vehicle diagnostic connectors for potential problems that might cause communication
interruptions.
There are now clip repair kits available through teamPSE to replace the retaining clips for two of
these cables. To protect the DRBIII(R) from internal damage, the clips are designed to fail at above
25 lbs. of axial force. Kits are described in the table.
It is a good practice to discard cables that have damage to the pins, cuts, corrosion, or general
damage beyond the retaining clips.

These vehicles use MMC based modules. The CH8432 Supplemental Reprogramming Tool (SRT)
was shipped as a 2001 Essential Tool. The flash reprogramming update files will be downloaded
from TechCONNECT Client to the SRT for flash reprogramming sessions on these vehicles. Users
should closely follow the instructions that come with the tool. If the tool has not been initialized,
there is a known condition where it may take up to 5 or more attempts for it to fully initialize and
become functional.
NOTE:
Once it has successfully flashed, it is initialized and no further action is required.
PREPARING TO FLASH
It is highly recommended that a sign, or other process, be used that notifies other users that a
FLASH SESSION IS IN-PROGRESS and must NOT be interrupted. Interrupting some flash
reprogramming sessions at critical junctures can render a module inoperative. Another user may
not realize that a flash session is in-progress and may disturb or disconnect the DRBIII(R) or do
something on the vehicle that could interrupt the flash process.
Before starting the flash session, read, record and erase all DTCs found on the vehicle.
Also "Cold Boot" the DRBIII(R) and download the flash since this will erase the flash file from the
DRBIII(R) memory. (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the
same time. Then press "F4").
Be sure to arrange the TechCONNECT and DRBIII(R) so that no cables are stretched across an
area where someone might trip over or kick a cable. When setting up your DRBIII(R), insure that it
rests on a surface where it will not fall or be bumped during reprogramming e.g.: DRBIII's have
been known to be swept off vehicle windshields by accident when a user bumps the wiper switch).
Check User settings on the DRBIII(R). From the DRBIII(R) Main menu, press 6,1 and check to
make sure item 1. Echo on PC is set to OFF. On occasion, when Echo on PC is set to ON, flash
reprogramming errors may occur.
VEHICLE BATTERY VOLTAGE
The flash programming procedure puts a load on the electrical system that may last from five to
twenty minutes depending on the particular flash reprogramming update. Connect a battery
charger to the vehicle. Set the charger to as close to 14 volts as possible. If the charger has a
timer, set it for 30 minutes BEFORE starting a flash reprogramming session. This will help to
prevent unwanted resets by either the DRBIII(R) and/or the vehicle module that are caused by
voltage fluctuations.
Alternately, as a bare minimum, use a "Battery Jump Box" when a battery charger is unavailable to
ensure adequate and stable system voltages on the module being flash reprogrammed.
POLICY: Information Only

This bulletin is supplied as technical information only and is not an authorization for repair.
Connected/Disconnected Flash Mode Using TechCONNECT
CONNECTED MODE FLASHING USING TechCONNECT
NOTE:
Capable but not recommended.
In this mode, the DRBIII(R) remains connected to the TechCONNECT Client and the vehicle
throughout the flash session. The DRBIII(R) is connected to the TechCONNECT Client using the
GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the CH7000A for most
vehicles).
This mode is useful when the TechCONNECT Client is next to the vehicle being flashed.
Another advantage of this mode is that you are able to determine all available flash updates for the
vehicle you are connected to by clicking on the "Read Part Number(s) From Vehicle" button.
Again, it is important that other users do not attempt to reboot or move the TechCONNECT Client
while a flash update is in-progress.
The reprogramming procedure of this mode is initiated by selecting the controller option and
clicking "Download/Update" button on the TechCONNECT client.
DISCONNECTED FLASH MODE
NOTE:
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3104
This is the preferred method.
This mode allows a user to flash a vehicle without being connected to the TechCONNECT Client.
This is a popular mode for flashing in a remote area of the service garage or in a back lot.
Before you attempt to use this mode, you must configure the DRBIII(R) for the desired update(s).
To do this, you must connect the DRBIII(R) to the TechCONNECT Client using the GPIB cable and
the CH7025 cable. It is not necessary to be connected to a vehicle. The GPIB (CH7035) cable will
be used to communicate with the TechCONNECT Client (for update file downloading) while the
CH7025 cable is used to provide power to the DRBIII(R).
After making the above connections, you are able to select one or more updates that you want to
perform. These selections are made by highlighting the desired updates and then clicking on the
"Download/Update" button by selecting the DRBIII(R) option on the TechCONNECT client.
Obviously, the DRBIII(R) does not have unlimited memory. If the file size of the selected updates
exceeds 948 KB, the "DRB Space Used" indicator (at the bottom-center of the TechCONNECT
Client screen) will change color from GREEN to RED. At this point you must de-select entries until
the indicator changes color to GREEN again.
When the updates have finished downloading, you may disconnect from the TechCONNECT Client
and take the DRBIII(R) to wherever the vehicle is located. The updates will remain in DRBIII(R)
memory for 8 hours while the DRBIII(R) is without power. If the DRBIII(R) is powered up for several
minutes before the 8 hour time period has expired, the update files will remain on the DRBIII(R) for
another 8 hours without power.
To start the actual flash process, after connecting to the vehicle in Disconnected Mode, you must
press "7 - Vehicle Flash" from the Main Menu on the DRBIII(R). Step by step instruction will follow
on the DRBIII(R) display. As with Connected Flash Mode, take the necessary precautions to insure
that others are aware of the flash session and that nothing disturbs the vehicle, DRBIII(R), or
cabling while performing the flash. Remember to use a battery charger set to 14 volts or a "battery
jump box".
Pay Attention While Performing Flash Reprogram Procedures
PAY ATTENTION WHILE PERFORMING FLASH REPROGRAMMING PROCEDURES
Before downloading the flash files, double check to see if the files that you have selected are the
appropriate ones for that vehicle. Don't forget about the "Read Part Numbers From Vehicle" option
on TechCONNECT Client, this can be of great assistance when trying to flash a module. If the files
selected don't download on the first attempt, try again.
The technician should NOT leave the vehicle when flash reprogramming a module.
Again, check to make sure that all cable connections are secure and that the DRBIII(R) rests on a
stable surface. If you are using a battery charger, insure that the settings and charging times are
correct and that the battery post clamps are securely fastened.
Read, record, and erase all DTCs found on the vehicle. Read and record the module type and part
number from the module that is to be flash reprogrammed.
Some control modules are not "abort-recovery" capable. When this is true, the scan tool will
indicate so by displaying a WARNING message prior to the start of reprogramming. For these
modules it is especially important that all precautions and procedures, outlined here, are carefully
followed.
Pay special attention to DRBIII(R) screen directions relating to key cycles. Missing a "Key ON" or
"Key OFF" can cause the module to have to be reflashed again. Due to the variety of module types
and vehicle options, you can't always anticipate key prompts, so be alert and ready to respond to
DRBIII(R) instructions.
Some screens will also instruct that certain modules, connectors or fuses be disconnected or pulled
prior to the start of reprogramming and re-installed immediately after completion. Be careful not to
anticipate the steps or order of operations for reprogramming any vehicle modules. Because of the
many possible changes that occur with each new release of scan tool software, always allow the
TSB/Recall and scan tool instructions to be your guide while performing flash reprogramming.
Flash reprogramming sessions usually range from 5 to 20 minutes. If the flash session has not
completed within 25 minutes after starting a flash reprogramming update, an error has most likely
occurred (Record the message that appears on the screen when a failure occurs). If this is the
case, or if you know that the flash process was interrupted, cycle the ignition key (OFF to the
locked position, then back ON). Reset the DRBIII(R) (power down for 4 seconds and then power
up) before attempting to restart the flash process. If the module still won't respond, turn the ignition
key off, disconnect the module from the vehicle for 2 minutes, reconnect the module, turn the
ignition key to run and try to restart the flash process again.
Regardless of what mode that you are in (Connected Flash or Disconnected Flash), if you have
tried twice (2 times) unsuccessfully to do a flash recovery and ALL DRBIII(R) instructions were
followed, perform the following:
^ Cold boot the DRBIII(R). This resets memory and removes all update files from the DRBIII(R).
(Push MORE and YES buttons at the same time, then press F4).
^ Reload the flash update file from the TechCONNECT Client.
^ If it fails to complete in the connected mode, first reboot the TechCONNECT Client before
re-attempting the flash download to the DRBIII(R).

Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3105
^ Proceed to reflash the module.
On vehicles that have multiple flash updates available, always complete and verify each flash
update before attempting the next one.
After all flash reprogramming is completed, read and erase all DTCs in all modules on the vehicle.
A variety of DTCs may be set, which are usually related to a loss of communication with the
module(s) being reprogrammed.
Verify the update by reading the new part number using the DRBIII(R). A good double check is to
read the part number using DRBIII(R) stand alone.
At times, other modules, wired in parallel, to the DLC connector have prevented flash
reprogramming sessions to be successful. After the failed attempt, review the appropriate wiring
diagram for the vehicle you are flash reprogramming and, with the key "OFF"; disconnect the other
modules and retry the flash. Complete the flash, turn the key "OFF" and reconnect any modules
that were disconnected. Refer to the "Programmable Modules" section later in this document for
more information.
Error Messages
ERROR MESSAGES
Block Echo/Compare Errors
Block Echo and Block Compare errors are often caused by voltage fluctuations, faulty I/O cables
(CH7OOOA, CH7005, CH7010) or faulty communication connections at the diagnostic connector.
Inspect for these conditions and review the sections on Vehicle Battery Voltage and Cable
recommendations.
Checksum Errors
Checksum Errors are generally caused by corrupt flash update files, which can be caused by
DRBIII(R) memory problems. If the DRBIII(R) has been without power for more than 8 hours, the
update files and system memory could be in a corrupted state. "Cold Boot" the DRBIII(R). (To
"Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press
"F4"). Reload the flash update file(s) from the TechCONNECT CLIENT. If it fails to complete in the
connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to
the DRBIII(R). Then re-attempt the flash reprogramming process.
Enhanced and Original Abort Recovery
ENHANCED ABORT RECOVERY
Interruptions in the flash process are one of the main reasons for failed flash sessions and
non-responsive (NR) modules. Interrupting the flash process after the erase phase has started will
leave the control module in a non-functional state.
Generally, but not always, NR modules may be recovered successfully.
Briefly, abort recovery is the process used to get a NR module back to a fully functional state with
the latest software update. The technician should be familiar with the other sections in this
document and follow all DRBIII(R) user prompts carefully.
There are two methods for abort-recovery. The newer method is called "Enhanced Abort
Recovery". This is the preferred method since the original method takes several minutes longer
and requires the correct selection of module type from a list of possible PCM's or TCM's.
Starting with Release 60.1, a new useful feature was added to the flash reprogramming application
for Engine and Transmission control modules. The DRBIII(R) "writes" the YME and Controller Type
information to a "Safe Memory" location. This method allows for rapid recovery of the module part
number and minimizes errors that could otherwise be made by selecting the wrong controller type.
It also assumes that the user will attempt abort recovery for a failed flash attempt before moving to
another vehicle with the same DRBIII(R). If you need to move to another vehicle for flash
reprogramming you must erase the saved recovery information in order to successfully perform
flash reprogramming. Be careful to match the YME information displayed on the enhanced abort
recovery screen with the vehicle and module that you are attempting to recover. If you use the
recovery file on a different vehicle and module you could damage the module.
The recovery information will be displayed on your DRBIII(R), at the start of a flash session, only if
you previously encountered a problem that prevented a flash session from completing normally. If
your prior flash session was successful, the DRBIII(R) automatically erases the recovery file so that
the flash application will not show any recovery information at the start of your next flash session.
Enhanced abort recovery features:
^ Reduces the amount of time for the Module ID process.
^ Lowers the risk of possible user mistakes by presenting the user the Year, Model, Engine, and
Controller Type.
^ Currently only applicable to Engine and Transmission flash reprogramming.
^ The enhanced abort recovery file will only be erased upon a successful flash or manually by the
user.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))

Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3106
^ Cold booting (simultaneously pushing MORE & YES, then F4) the DRBIII(R) will not erase the
enhanced abort recovery file, but cold booting the DRBIII(R) will still erase the flash file so it can be
reloaded.
^ The user has a choice, at the start of a flash session, whether or not to use the enhanced abort
recovery feature. If the user chooses to erase the recovery file, then the DRBIII(R) will use the
original method of abort recovery.
^ Cycling the ignition key, when prompted by the DRBIII(R), is still necessary to put the controller
into bootstrap (reprogramming) mode.
ORIGINAL ABORT RECOVERY
If the choice is made to use the original method of abort recovery, a NR module is not always able
to provide the DRBIII with ID information. In this case the technician must enter this when prompted
by the DRBIII(R). Be patient when performing this process. If the module does not respond to
standard diagnostic requests, the DRBIII(R) may take several minutes before it determines that the
engine module is in a NR state. At this point, the DRBIII(R) displays the prompt "Could not
determine engine controller type. Please select from list" along with a list of possible controller
types (if the DRBIII(R) is attempting to identify a TCM, the prompt will say "trans" instead of
"engine" and list the possible trans controller types). Because of module variations, it is important
to correctly identify the PCM/TCM type so that the correct flash procedure is used. Failure to do
this will cause further problems and may damage the module. Tables are provided below to help
identify the proper module type to select. These tables correctly identify the modules that were on
the vehicles when they were built. However, some vehicles will have module types which were
superseded to a new type when a replacement part was installed (ie: EATX4 modules replaced
with an EATX4A). Correctly identify these modules using DRBIII(R) Standalone prior to attempting
flash reprogramming.
NOTE:
When instructed to turn the key to the LOCKED position, be sure that the key is not just turned to
the OFF position. The key must be rotated to the point at which it can be removed from the ignition
switch. On most vehicles the switch is on the steering column and at this position the steering
column is LOCKED. When instructed to turn the key to the RUN position, be careful not to turn the
key past this position which may engage the starter motor. This creates electrical noise which
interferes with the flash process.
General Steps for Abort Recovery
1. Review all Tips and Techniques before continuing. Pay special attention to the section on
Preparing to Flash a controller and to the Programmable Modules section.
2. Cycle the vehicle's ignition key to the LOCKED position and back to the RUN position.
3. Reset the DRBIII(R) by disconnecting the vehicle cable from the DRBIII(R) for 4 seconds and
then reconnecting the cable.
4. Depending on where the flash session was aborted, the DRBIII(R) may require that the
technician identify the control module type that was being flash reprogrammed. Use the PCM/TCM
configuration table below as a guide. This step is not necessary if using the enhanced abort
recovery method.
5. After selecting the proper control module type or choosing enhanced abort recovery, follow the
prompts that are displayed on the DRBIII(R).
NOTE:
If an error message is displayed at this point, an incorrect module type was most likely selected. If
this occurs, start the process over.
6. If the recovery process is unsuccessful, perform the following:
a. Review the TSB/Recall notice (authorizing the flash update) and all Tips and Techniques in this
document.
b. Reboot/Restart the TechCONNECT Client.
c. "Cold Boot" the DRBIII(R). (Press the MORE and YES buttons on the DRBIII(R) at the same
time, then press F4).
d. Start this process over from item # 1. If using Disconnected Mode, the flash update will have to
be reloaded from the TechCONNECT Client or ISIS DVD.

Programmable Modules
The following pages list the various modules that have flash reprogramming capability. It does not
mean that a flash is currently available. What will be described are the module types and
variations, followed by items to note, and finally, abort recovery specifics if applicable.
Powertrain Modules - Engine and Transmission
ENGINE - POWERTRAIN CONTROL MODULE (PCM)

Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3111
There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions that are
somewhat unique to each type will have comments. Prior to reprogramming a PCM, retrieve the
module information and module type using your DRBII I®. PCM information is used by many
modules. Be sure to check DIG's before and after performing all flash reprogramming event.
The DTC's associated with flash reprogramming generally relate to "lack of communication" with
the other modules during the reprogramming session.
SBEC
Types:
SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B
NOTE:
During recovery, if the DRBIII® is not seeing the key off, you may need to remove power (B+) to
PCM by removing fuse(s) or disconnecting the PCM. When DRBIII® states to turn key ON,
reconnect fuse or harness connection.
Abort Recovery Specifics:
^ Follow instructions on the DRBIII® for the module type. See table above.
^ Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not correctly
identify a key cycle. In this case a Modified Key Cycle routine is required.
This state is present when the following message is displayed on the DRBIII(R): "Can not read Part
Number. Did not see Key On or PCM/TCM Controller may not be flashable". When this occurs
restart the flash session and when prompted to turn the ignition key to the LOCKED position, pull
the fuse(s) that supply battery power to the module instead. When prompted to turn the key to the
RUN position, replace the battery supply fuse(s) instead.
JTEC
Types:
^ JTEC, JTEC+
NOTE:
Viper ALL - Roll down windows especially Coupes before attempting a flash.
NOTE:
1999 WJ JTEC with Speed Proportional Steering module. Disconnect before and reconnect after
the PCM flash reprogramming session. Also see Transmission.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
NGC Types:
^ NGC 1, NGC 2, and NGC 3
NOTE:
There are derivatives of NGC 3 that will be significant when reprogramming and or testing. NGC
modules use one of the longest time spans for flash reprogramming (approximately 15 minutes).
The NGCI and NGC3 controllers incorporate both an engine as well as a transmission controller in
a common package. The NGC2 controller incorporates the engine controller and an Electronic
Throttle Control (ETC) module in place of the TCM. All NGC controllers can be visually identified by
noting its four (4) wiring connectors. On manual transmission applications and the NGC2, only 3
connectors may be populated with pins.
NOTE:
On certain vehicles, the ABS CAB module connector MUST be disconnected prior to performing
this Repair Procedure. The CAB module and the PCM are connected at the same diagnostic
connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB module
connector, and reprogram the PCM per the Repair Procedure. When reprogramming is complete
turn the ignition switch to the OFF position, connect the CAB module connector, and then check for
DTC's. If the PCM becomes "locked" during reprogramming because the ABS CAB module
connector was not disconnected, then the PCM may be recovered by following the procedure in
this NOTE.

^ 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement EATX4A part
numbers 56041814AD and 56028227AH currently display a P/N read failed error after the flash is
completed during PIN verification. This DOES NOT mean the flash failed. Check for the part
number using DRBIII(R) in standalone mode. This exists only for the service replacement modules
listed above. Flash reprogramming for OE modules flash and read the part number correctly.
Follow DRBIII(R) prompts carefully.

provides transmission control functions on Dodge trucks and Jeep vehicles. Additionally, they are
used on some Cummins equipped Dodge trucks with manual and automatic transmissions.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
PRE 1996 EATX TRANSMISSION CONTROL MODULES
Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX controller
only to the PCM. Those vehicle TCMs only communicate to the DRBIII(R) using CCD
communications.
For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting those
modules to the DRBIII(R) vehicle connector.
For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because of this
you will need to use the Yellow SuperCard2, CH8361,to set pinion factor or when using a "new"
(superseded) TCM from parts as only the SuperCard2 properly sets the pinion factor on these
updated modules.
Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124.
The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin
18-24-95.

Owner Letter
EMISSIONS RECALL TO REPROGRAM YOUR VEHICLE'S POWERTRAIN CONTROL MODULE
Dear DaimlerChrysler Vehicle Owner:
DaimlerChrysler has determined that some 1998 Dodge Dakota, Durango, Ram Van/Wagon, Ram
Truck, and Jeep(R) Grand Cherokee vehicles, equipped with a V-8 or V-10 engine, may be in
violation of California Emissions Regulations.
The problem is...
The On-Board Diagnostic (OBD) system on your vehicle (identified on the enclosed form) may not
detect evaporative emissions purge system malfunctions as required by California Emissions
Regulations. As a result, the OBD system on your vehicle may not illuminate the "Check Engine"
light if the evaporative emissions purge system malfunctions. This could cause your vehicle to emit
hydrocarbon levels above the limits that were established to protect the public health from the
dangers of air pollution.
Hydrocarbons (unburned fuel) combined with oxides of nitrogen, in the presence of sunlight, can
cause the formation of ozone. These pollutants are the primary components of smog.
What DaimlerChrysler and your dealer will do...
DaimlerChrysler will repair your vehicle free of charge (parts and labor). To do this, your dealer will
reprogram your vehicle's powertrain control module. The work will take about 1/2 hour to complete.
However, additional time may be necessary depending on how dealer appointments are scheduled
and processed.
What you must do...
^ Simply contact your dealer right away to schedule a service appointment.
^ Bring the enclosed Owner Notification form with you to your dealer. It identifies the required
service to the dealer.
If you live in California and don't get this done...
The State of California requires the completion of emission recall repairs prior to vehicle
registration renewal. In addition, the State requires that every vehicle must pass an emission test
(SMOG Check) every two years and before it is sold. Without the free service we are providing,
your vehicle may be more likely to fail this test and require that you make costly repairs.
How the state knows that the recall has been performed...
State of California regulations require DaimlerChrysler to provide the Department of Motor Vehicles
with a record of all vehicles that have not had the recall service performed. If you live in the state of
California and your vehicle is not on this list, the state will know that the recall has been completed.
Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the
recall service is completed. Be sure to save this form since the California Department of Motor
Vehicles may require that you supply it as proof of recall completion.
If you need help...
If you have trouble getting your vehicle repaired, please call the DaimlerChrysler Customer
Assistance Center, toll free, at 1-800-992-1997. A representative will assist you in getting your
vehicle repaired.
In order to ensure your full protection under the emission warranty provisions, it is recommended
that you have your vehicle serviced as soon as possible. Failure to do so could be determined as
lack of proper maintenance of your vehicle.
We are sorry for any inconvenience but trust you understand our interest in clean air and your
continued satisfaction with our products. Thank you for your attention to this important matter.

NOTE:
THIS INFORMATION APPLIES TO NATURALLY ASPIRATED (NON-TURBO) GASOLINE
ENGINES.
DISCUSSION:
Some states that require I/M inspections are beginning to include OBD II "CARB" Readiness as a
prerequisite to an I/M test. OBD Readiness tells an I/M station if the OBD II systems have run their
self test. Owners, in those states that use OBD Readiness, may be denied an I/M test if one or
more of the Readiness monitors read "NO" or in other words the OBD II monitors have not run their
tests.
It is important to understand that the MIL will not be illuminated because OBD Readiness reads
"NO". MIL illumination happens when an actual malfunction or failure of a monitored emissions
system occurs. It is possible to have MIL illumination for a detected failure while at the same time
having a "NO" for an OBO Readiness monitor.
NOTE:
MIL ILLUMINATION INDICATES ADDITIONAL PROBLEMS WITH THE VEHICLE. FURTHER
DIAGNOSIS AND REPAIR WILL BE REQUIRED BEFORE PROCEEDING FURTHER WITH THIS
BULLETIN.
OBD Readiness that reads "NO" can be caused by the following: PCM reprogramming, PCM
replacement, fault code erasure, battery disconnects and/or replacement. If any of the above items
occur before an I/M test, a good chance exists that one or more of the monitors will read "NO" for
OBD Readiness.
Some customers may be directed back to their dealers for assistance when an I/M test station has
not allowed an I/M test due to Readiness status. The following procedures will help technicians
efficiently run the Readiness tests so an owner can have their I/M test completed.
EQUIPMENT REQUIRED:
1 CH6OOO Scan Tool (DRB III(R))
1 CH7000/7001 J1962Cable
1 CH7OlO J1962 MMC Cable

Repair Procedure
This bulletin involves operating the vehicle under specific parameters to run or complete the OBD
monitors. The number of monitors applicable to a vehicle will vary by type of vehicle and emissions
application. In addition, the parameters to run each monitor will vary.
Preliminary Checks
1. Perform a MIL bulb check by switching the ignition key "ON" (engine off). The MIL will illuminate
as a bulb check. If the MIL does not illuminate, repair the bulb or bulb circuit.
2. Connect a DRB III(R) to the vehicle. Select DRB III(R) standalone, current model year
diagnostics, engine, DTC's and related functions, read DTC's.
3. Verity that no emission related DTC's are present and that the MIL is not illuminated with the
engine running.
NOTE:
EMISSION RELATED DTC'S AND MIL ILLUMINATION MAY PREVENT OTHER OBD MONITORS
FROM RUNNING. DTC'S THAT ILLUMINATE THE MIL MUST BE REPAIRED BEFORE
ATTEMPTING TO RUN THE MONITORS.
OBD "CARB" Readiness Check
1. With the DRB III(R) select engine, OBD II monitors, CARB Readiness Status.
2. Read the monitor status. "YES" tells you that monitor has run and is ready for an I/M test, "NO"
tells you that the monitor must be run. If all monitors listed read "YES", the vehicle can be returned
to the customer for completion of their I/M test. Only monitors that read "NO" must be run to read
"YES".
NOTE:
THE MONITORS LISTED IN THE OBD "CARB" READINESS SCREEN ARE THE ONLY ONES
APPLICABLE FOR THE VEHICLE BEING WORKED ON.
The vehicle must be operated in various conditions (speed, temperature, etc.) for the monitors to
run. Each monitor includes a pre-test and monitor test that can be viewed on the DRB III(R). The
pre-test/monitor test screen lists all the preliminary parameters that must be met along with the
running parameters for that specific monitor to run. An example of one screen is shown in Figure 1.

25-02-98 > Oct > 98 > I/M Testing - OBDII CARB Readiness Monitor Information > Page 3149
NOTE:
1997 AND PREVIOUS MODEL VEHICLES WILL HAVE A DIFFERENT LOOKING SCREEN.
PRESS THE F1 KEY TO OBTAIN MONITOR RUN CONDITIONS. THE WAY IN WHICH THE
MONITORS RUN WILL BE SIMILAR.
The following explains how to interpret each section of the screen:
PRE-TEST REQUIREMENTS
The pre-test requirements include all the operating parameters that must be met before the actual
test can run. The vehicle must be operated until each item within the pre-test section are fulfilled.
LOW VALUE/HIGH VALUE/BAR GRAPH
The low value/high value provides the minimum and maximum operating conditions for each item
(ie ECT Range must be between 170° and 260° F in Figure 1). The bar graph will begin to fill when
the lowest value required for each item is met. This provides a visual indication that the parameters
are being met. The vehicle should be driven until most of each pre-test bar graph is filled.
MONITOR REQUIREMENTS
Once all pre-test requirements are met, the vehicle must be brought within the parameters listed in
the monitor requirements section for the monitors to begin running. As the monitor begins to run,
the DRB III(R) will begin to beep. This is an audible indication that the test is in progress. If vehicle
operation falls outside any of the parameters, the beeping will stop. If this occurs, the technician
must determine if the pre-test requirements or the monitor requirements have fallen outside the
window for the test and the vehicle must be driven accordingly for the test to restart. When the
monitor completes its test, the DRB III(R) will beep 3 consecutive times.
NOTE:
THE PURGE FLOW PRE-TEST SCREEN WILL LOOK DIFFERENT THAN THE REST OF THE
PRE-TEST/MONITOR SCREENS. PRESS THE F1 KEY ON THE DRB III(R) TO SEE A SIMILAR
SCREEN FOR THIS MONITOR.
MONITOR RUN PROCESS
The following will provide the most efficient order along with tips to help run through the monitor
tests quickly. The monitors listed include all possible monitors for either Front Wheel Drive or Rear
Wheel Drive vehicles. The vehicle being worked on may have fewer monitors than the maximum
available. Only those listed on the DRB III(R) are applicable for the vehicle being worked on. The
only monitors that will require attention are those that read "NO" under the OBD "CARB"
Readiness Status screen.
Front Wheel Drive
1. Evaporative Leak Detection Monitor - This test will require a cold start (possibly an overnight
soak either indoors or out depending on conditions). The ambient (outside) temperature must be
between 4° and 32° C (40° and 90° F) with the engine coolant temperature within 6° C (10 ° F) of
ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen
on the DRB III(R) to determine the remaining requirements.
2. Catalyst Monitor - The vehicle must be driven at highway speeds for the time listed in the
pre-test screen. If the vehicle is equipped with a manual transaxle, use fourth gear to help meet the
requirements.
3. EGR Monitor - It is necessary to maintain TPS, MAP, and RPM ranges listed in the pre-test
screen for this test to complete.
4. O2 Sensor Monitor - The vehicle must be driven and brought to a stop for the time listed in the
pre-test screen. Automatic transaxle vehicles must be left in drive during the stop period.
5. Purge Monitor - To see a similar screen format as listed in Figure 1, press the F1 key on the
DRB III(R) while in the Purge Flow Pre-Test screen. The purge free (PF) cells must update and the
monitor will attempt to run on every other throttle closure. Automatic transaxle vehicles must be left
in drive for the test to run. If all parameters are met and the test still will not run, place your foot on
the brake, open the throttle to 1/4 and then quickly close the throttle. This should allow the PF cells
to update.
6. O2 Sensor Heater Monitor - The open throttle time for the O2 Heater pre-test must be exceeded.
This monitor will run after the ignition key is switched "Off". After the DRB III(R) switches to No
Response (approximately 3 minutes) turn the ignition key "On" and check the O2 Sensor Heater
monitor status. It should have switched to "YES". All other monitors should be completed before
running this test.
Rear Wheel Drive
1. O2 Sensor Heater Monitor - This test will require a cold start (possibly an overnight soak either
indoors or outdoors depending on conditions). The ambient (outside) temperature must be between
18° and 38° C (0° and 100° F with the engine coolant temperature within 6° C (10° F) of
ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen
on the DRB III(R) to determine the remaining

2. Evaporative Leak Detection Monitor - This test will require a cold start (possibly an overnight
soak either indoors or outdoors depending on conditions). The ambient (outside) temperature must
be between 4° and 32° C (40° and 90° F) with the engine coolant temperature within 6° C (10 ° F)
of ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test
screen on the DRB III(R) to determine the remaining requirements.
3. Catalyst Monitor - The vehicle must be driven at highway speeds for the time listed in the
pre-test screen. If the vehicle is equipped with a manual transmission, use 4th gear to help meet
the requirements.
4. O2 Sensor Monitor - The vehicle must be driven and brought to a stop for the time listed in the
pre-test screen. Automatic transmission vehicles must be left in drive during the stop period.
5. Purge Monitor - To see a similar screen format as listed in Figure 1, press the F1 key on the
DRB III(R) while in the Purge Flow Pre-Test screen. The purge free (PF) cells must update and the
monitor will attempt to run on every other throttle closure. Automatic transmission vehicles must be

NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH GASOLINE ENGINES AND A 42RE,
44RE, 46RE, OR 47RE TRANSMISSION.
SYMPTOM/CONDITION: At ambient temperatures of -20 C (-5 F) or below, the Powertrain Control
Module (PCM) will electronically inhibit the transmission from shifting into overdrive. This will
protect the transmission from damage if the transmission fluid begins to freeze. In extreme cold
climatic regions, this feature can cause customer dissatisfaction due to elimination of overdrive and
less than optimal fuel economy.
DIAGNOSIS: The cold weather by-pass kit along with disabling the inhibitor feature should only be
incorporated for vehicles used in areas of extended cold ambient temperatures.
NOTE:
THIS KIT WILL DECREASE THE MAXIMUM COOLING CAPACITY OF THE TRANSMISSION'S
COOLING SYSTEM. AS A RESULT, IT IS NOT RECOMMENDED THAT THIS BULLETIN BE
PERFORMED UNLESS THE ABOVE STATED CONDITION EXISTS. ALSO, IF THE VEHICLE IS
USED FOR MODERATE TO HEAVY TOWING IT IS NOT RECOMMENDED.

Repair Procedure
This bulletin involves installing a cold weather by-pass kit to the transmission cooler circuit,
selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software
(calibration changes for 1996 models only), and using the DRB III to selectively turn off the
overdrive inhibitor feature for all applications.
NOTE:
IT IS ESSENTIAL THAT THE TRANSMISSION COOLER BYPASS KIT BE INSTALLED PRIOR
TO DISABLING THE INHIBITOR FEATURE. TRANSMISSION DAMAGE MAY OCCUR IF THE
BYPASS KIT IS NOT INSTALLED.
NOTE:
EVEN WITH BYPASS KIT INSTALLATION AND THE INHIBITOR FEATURE TURNED OFF, 4TH
GEAR WILL BE INHIBITED UNTIL THE OIL SUMP TEMPERATURE REACHES 0 C (30 F). THIS
MAY TAKE SEVERAL MINUTES.
Bypass Kit Installation
1. Record all radio pre-sets and disconnect the negative battery cable.
2. Raise the vehicle for access to the transmission housing. The bypass assembly will be
connected to the existing transmission lines and mounted to the transmission housing by means of
a bypass adapter.
3. During this installation procedure, some transmission fluid will be lost when the transmission
cooler lines are cut (allowing bypass assembly installation). Take proper precautions and check
transmission fluid fill level upon completing the installation.
4. It the cold weather bypass kit has provision for an in-line temperature sensor, the threaded
"therm-o-well" (in the pressure "P" line of the kit) must be plugged with either the temperature
sensor from the existing transmission line or the standard pipe plug provided. Consequently, if the
vehicle being serviced is equipped with a temperature sensor (i.e., heavy duty BR truck), remove
the temperature sensor from the existing line by un-threading and install it in the "pressure" line
provided with the kit. Use Mopar Thread Sealant, p/n 04318044, to ensure a leak free seal.
5. Disconnect the pressure and return lines from the transmission housing fittings.
6. Remove and discard the fittings from the transmission housing.
7. Apply Mopar Thread Sealant, p/n 04318044, to the threaded bypass adapter (# 2 Figure 1).
8. Install the threaded bypass adapter securely into the front pressure port of the transmission
housing and torque to 17.6 Nm (13 ft. lbs.).
9. Make sure the snap ring and O-ring are properly installed in their respective grooves on the nose
of the bypass assembly block. Lubricate the O-ring with ATF.
10. Position the bypass assembly block such that the return port fitting "R" is pointed directly up
and the two other fittings are pointed forward.
11. Firmly press the male nose of the bypass assembly into the female body of the threaded
bypass adapter until it snaps into place. After snapping into place, the bypass assembly is
permanently attached to the adapter.
NOTE:
THE BYPASS ASSEMBLY CAN ROTATE INSIDE THE ADAPTER, AND REMOVAL OF THE
BLOCK FROM THE TRANSMISSION HOUSING (IF REQUIRED) CAN BE ACCOMPLISHED BY
UN-THREADING THE ADAPTER.
CAUTION:
IF FLUSHING THE BYPASS ASSEMBLY IS REQUIRED, IT MUST BE REMOVED FROM THE
TRANSMISSION HOUSING AND FORWARD FLUSHED ONLY. FAILING TO REMOVE THE
VALVE AND REVERSE FLUSHING WILL RESULT IN TRANSMISSION FAILURE BY PLUGGING
THE BYPASS VALVES INTERNAL ORIFICE AND DRAIN BACK VALVE.
12. Apply Mopar Thread Sealant, p/n 04318044, to the threaded end (transmission housing end) of
the compression fitting.
13. Install the threaded compression fitting securely into the rear return port of the transmission
housing and torque to 17.6 Nm (13 ft. lbs.).

14. Using a small tubing cutter, cut the existing pressure line at approximately 120 mm (5 in.) from
the transmission housing end. Repeat the procedure for the existing return line.
CAUTION:
AFTER CUTTING THE PRESSURE LINE, MARK IT WITH A PIECE OF TAPE FOR
IDENTIFICATION.
15. Identify the proper return line ("R" line) by using the marked labels attached to the tubes.
16. Connect the "R" line to the bypass assembly block and the rearward return port of the
transmission housing. Tighten the compression fitting finger tight, and then wrench tighten it an
additional 1/2 turn. Tighten the inverted flare nut to 6.78 Nm (60 in. lbs.).
17. Select the appropriate "RR" and "P" tubes for the application. Mixing or matching may be
required to provide the best routing for your

18. Loosely connect the pressure line "P" to the pressure port fitting "P" on the bypass assembly
block.
19. Loosely connect the radiator return line, "RR" to the "RR" port fitting, on the bypass assembly
block.
NOTE:
DURING THE INSTALLATION OF THE "P" AND "RR" LINES, THE ORDER MAY BE REVERSED
TO AID IN THE ASSEMBLY PROCESS.
NOTE:
ON 5.2L ZJ MODELS, THE THROTTLE VALVE CABLE AND BRACKET MAY REQUIRE
REMOVAL FOR BYPASS TUBE CLEARANCE. ONCE THE TUBES ARE INSTALLED LOOSELY,
INSTALL THE BRACKET AND THROTTLE VALVE CABLE. MAKE ANY ADJUSTMENTS FOR
CLEARANCE AND TIGHTEN THE BYPASS TUBES AND BRACKET ASSEMBLY.
20. Make sure that the existing return line is properly re-attached to the hanger bracket and lay the
new return line, "RR", beside it.
21. Install the hose bracket (# 12 in Figure 1) required for the overhead line application. The
bracket will replace the existing bracket at the starter mount location. It may require slight
modification to provide the best clearance from the exhaust system.
22. Attach clamp (# 11 in Figure 1) and the rubber hose to the "RR" tube to determine the
approximate rubber hose routing. For connection to the existing return line, the line may be cut
again to provide optimum line routing.
CAUTION:
WHEN ROUTING THE TUBING AND HOSE BE AWARE OF POTENTIAL MOVING
COMPONENT INTERFERENCES, SUCH AS THE PROPELLER SHAFT, SHIFT LINKAGE IN ALL
POSITIONS, TV CABLE, TV RETURN SPRING, AND TV LINKAGE. BE AWARE OF THE
EXHAUST SYSTEM, ALL ROUTINGS SHOULD MAINTAIN AT LEAST ONE INCH OF
CLEARANCE FROM THE EXHAUST SYSTEM.
23. Cut the rubber hose so that it has sufficient length to be attached to the existing return line.
24. Loosely connect a nut (# 7 in Figure 1), a compression sleeve (# 8 in Figure 1), and a hose
fitting (# 10 in Figure 1) to the existing return line.
25. Using a clamp (# 11 in Figure 1), install the rubber hose onto the hose fitting (# 10 in Figure 1).
26. Evaluate the line routing to ensure moving components and exhaust will not interfere with the
new lines. Make modifications as necessary to provide the best routing.
27. Disconnect the "RR" tube from the Bypass Block for access to the "P" port on the block
assembly.
28. Attach a clamp and the rubber hose to the "P" tube and determine the approximate rubber hose
routing. For connection to the existing pressure line, the line may be cut again to provide optimum
line routing.
CAUTION:
WHEN ROUTING THE TUBING AND HOSE BE AWARE OF POTENTIAL MOVING
COMPONENT INTERFERENCES, SUCH AS THE PROPELLER SHAFT, SHIFT LINKAGE IN ALL
POSITIONS, TV CABLE, TV RETURN SPRING, AND TV LINKAGE. BE AWARE OF THE
EXHAUST SYSTEM, ALL ROUTINGS SHOULD MAINTAIN AT LEAST ONE INCH OF
CLEARANCE FROM THE EXHAUST SYSTEM.
29. Cut the rubber hose so that it has sufficient length to be attached to the existing pressure line.
30. Loosely connect a nut (# 7 in Figure 1), a compression sleeve (# 8 in Figure 1), and a hose
fitting (# 10 in Figure 1) to the existing pressure line.
31. Using a clamp (# 11 in Figure 1), install the rubber hose onto the hose fitting (# 10 in Figure 1).
32. Evaluate the line routing to ensure moving components and exhaust will not interfere with the
new lines. Use tie straps and rubber bumpers on the hose to protect the hose from metal surfaces
that may cause chaffing.
33. Torque both clamps, the compression fitting (finger tight, then wrench tighten 1/2 turn), and the
inverted flare nut to 6.78 Nm (60 in. lbs.) on the "P" line.
34. Connect the "RR" ling and torque both clamps, the compression fitting (finger tight, then wrench
tighten 1/2 turn), and the inverted flare nut to 6.78 Nm (60 in. lbs.) on the "P" line.

DISCUSSION:
NOTE:
Many of the reasons a flash reprogramming procedure may not complete are documented in this
service bulletin, but if you are constantly having issues performing the flash reprogramming
procedure using a specific DRBIII(R), it is suggested you send the DRBIII(R) in question to
SPX/Miller Special Tools for service.
Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment
may lock up or become disconnected during the procedure. Flash Reprogramming is a "CRITICAL
PROCESS"; an error may result in a no-start/failed control module. Most modules, encountering an
interruption or failure while reprogramming, are recoverable; a recoverable module is not covered
under the provisions of the warranty.
This service bulletin covers items that may cause this condition, a process to restart the flash
procedure, and miscellaneous information that will help prevent needless replacement of control
modules.
GENERAL: Flash Reprogramming is only authorized by a specific SERVICE BULLETIN, or
RECALL.
Review the entire Service Bulletin/Recall prior to performing a flash reprogramming update. Often
other parts may need to be serviced, replaced, or tested, prior to flash reprogramming, and ARE
REQUIRED as part of completing the Service Bulletin/Recall.
When flashing a Powertrain Control Module (PCM) or Transmission Control Module (TCM) there
are other legal requirements with labeling issues that are included in those service bulletins.
Other non-emission related modules, such as instrument clusters and Body Control Modules
(BCMs) do not require labels.
FLASH REPROGRAMMING SEQUENCE OF EVENTS
The process of flash reprogramming is similar to flashing the BIOS on a Personal Computer.
Interruptions, voltage problems, and a variety of other outside interactions can potentially interfere
with the process. This document seeks to provide information to minimize problems associated
with vehicle control module flash reprogramming. The description that follows is for most PCMs
and some TCMs. Other modules use different initiation procedures.
The process starts by selecting an update from the TechCONNECT Client or ISIS and then
"loading" that update into the DRBIII(R). Once the flash reprogramming update is loaded into the
DRBIII(R), and before the flash reprogramming begins, the DRBIII(R) verifies that the update
loaded from the TechCONNECT Client or ISIS is the proper update for the module. This is done
using part number supersedence. This verification occurs only if an update is required, available
(on the TechCONNECT Client or ISIS) and has been selected for programming.
^ The module is then placed into "Boot Strap" programming mode by the DRBIII(R). This module
mode gives the DRBIII(R) permission and the ability to proceed with the flash reprogramming
session.
^ Next, the current part number, which resides in the module's flash memory, is stored in a "Safe
Memory" location within the module. This memory location is not affected by flash memory erasure
and reprogramming, which are to follow.
^ Once the part number is safely stored, the flash memory in the control module is erased. From
this point forward any interruption in the flash process,
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3172
will result in a Non-Responsive module (NR). A NR module is a module that is either partially
erased or partially programmed.
^ After erasure, the actual reprogramming procedure starts, and the update software is
programmed into the flash memory within the module.
^ When reprogramming is completed, the flash memory is verified through an internal process in
the DRBIII(R) using a "Check Sum". This value is compared against another value that represents
what should be in memory and when matched, verifies successful reprogramming.
^ Next, a DRBIII(R) prompt is displayed instructing that the ignition switch be turned OFF. The
module exits the "Boot Strap" mode when the switch is turned off.
^ After a slight pause, the DRBIII(R) will prompt for the ignition switch to be turned ON. The
DRBIII(R) then reads the new part number in flash memory (along with a new computer program
the new part number is placed into the module's memory). If the new part number matches the
expected part number, the flash reprogramming session has completed successfully.
SOFTWARE VERSIONS MUST BE CURRENT
Before attempting a flash reprogramming session using the TechCONNECT Client, make sure you
have the most current DRBIII(R) software installed.
To verify whether your DRBIII(R) software is current, check the upper right-hand corner of the
TechCONNECT Client screen for DRBIII(R) Available Version, DRBIII(R) Current Version.
Often, because of multiple DRBIII(R)s in the shop, not all will get updated on a timely manner. The
installed DRBIII(R) software version can generally be found at the bottom center of most screens.
Alternately the version can be checked by pressing 6, 2, 5 from the DRBIII(R) Main Menu and
comparing it to what is available from a current TechCONNECT Client as described above.
If the TechCONNECT Client is current and the DRBIII(R) is not, it may be due to the fact that the
TechCONNECT Client does not force DRBIII(R) updates for "minor" revisions. Changes and new
support are added to the Vehicle Flash application on "minor" revisions on a regular basis. This is
why your TechCONNECT Client and DRBIII(R) must have the LATEST software revisions
installed.
DO NOT PASS on the option for updating to a "minor" revision!
Major updates require the DRBIII(R) to be updated prior to allowing any flash programming.
DRBIII(R) CABLES
A NEW DRBIII(R) cable was released as an Essential Service Tool! CH7000A - 8 ft.
Cable, DRBIII(R) to OBDII (J1962) DLC Connector.
CH7000A is the required cable for ALL flash reprogramming. The older CH7000 cable can be used
for diagnostics ONLY. One (1) cable was shipped to all dealerships. Easily identified, the correct
cable has a RED connector, which plugs into the DRBIII(R).
The cable modification enhances the DRBIII(R) communication capabilities when dealing with the
flash requirements of certain controllers/ECUs affected in part by the recent changes in DLC
connector configurations.
The new cable is required for ALL flash reprogramming sessions, and can be used wherever the
previous CH700017001 cables were used.
While not recommended for flash reprogramming usage, if you require a longer cable, there is also
a 12-foot cable released under pin CH7001A
The production of the previous CH700017001 cables has ceased. All orders placed will be
superseded to part number CH7000A/CH7001A.

NOTE:
Consider all cables wear items. Always inspect for worn, damaged cables, connectors that are
damaged or do not lock securely, and all mating connections including checking for corrosion on
the pins. REPLACE ALL suspect cables. Do not use worn or damaged cables when flash
reprogramming.
Failure to use the new cable or to use a damaged cable often results in failed flash reprogramming
sessions.
The 2 door Sebring, Stratus, and Avenger coupes (supplied by MMC) generally use the CH7O1O
cable (Pre-OBDII MMC vehicles will use the CH7005 cable).
TechCONNECT CABLE (GPIB)
Replace any suspect GPIB cable.
The GPIB cable provides the connection between TechCONNECT Client and the DRBIII(R).
This cable is used by the TechCONNECT Client for vehicle part number reads and to send update
files to the DRBIII(R).
Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If
this cable becomes disconnected during a flash session, you may have to reload the update file
that you selected on the TechCONNECT Client.
TROUBLESHOOTING CONNECTIVITY OF THE DRBIII(R) UNIT TO THE TechCONNECT
APPLICATION.
1. Turn-on the power to the DRBIII(R) unit.
2. Select option 2 "Connect to TechCONNECT" and press Enter.
3. Attach the male mini D-shell amphenol GPIB connector of the new DRBIII(R) cable (part number
CH7035B) to the DRBIII(R) unit.
4. Insure that the larger female D-shell amphenol GPIB connector of the new DRBIII(R) cable is
properly attached to the male D-shell amphenol GPIB connector on the GPIB-USB-B protocol
converter, (part number CHGPIB-B).
5. Attach the USB cable from the GPIB-USB-B protocol converter to one of the USB ports on the
rear panel of the client CPU.
6. When the cable is attached to the USB port of the CPU for the first time, Windows 2000 will
detect the device and install software for it. Please wait for 25-30 seconds to complete the
installation.

ISIS NULL MODEM CABLE
Replace any suspect null modem cables.
International (ISIS), a PC-based CD program similar to TechCONNECT Client uses a null modem
cable for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for
loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes
disconnected during a flash download session, you will have to reload the update file or files.
GENERAL NOTES FOR CABLES AND VEHICLE CONNECTIONS
Consider ALL cables to be wear items.
Many successful dealers have dedicated cables devoted to "Flash ONLY".
Always have spare CH7000A, CH7010 and CH2002 GPIB or null modem cables available.
Inspect vehicle diagnostic connectors for potential problems that might cause communication
interruptions.
There are now clip repair kits available through teamPSE to replace the retaining clips for two of
these cables. To protect the DRBIII(R) from internal damage, the clips are designed to fail at above
25 lbs. of axial force. Kits are described in the table.
It is a good practice to discard cables that have damage to the pins, cuts, corrosion, or general
damage beyond the retaining clips.

These vehicles use MMC based modules. The CH8432 Supplemental Reprogramming Tool (SRT)
was shipped as a 2001 Essential Tool. The flash reprogramming update files will be downloaded
from TechCONNECT Client to the SRT for flash reprogramming sessions on these vehicles. Users
should closely follow the instructions that come with the tool. If the tool has not been initialized,
there is a known condition where it may take up to 5 or more attempts for it to fully initialize and
become functional.
NOTE:
Once it has successfully flashed, it is initialized and no further action is required.
PREPARING TO FLASH
It is highly recommended that a sign, or other process, be used that notifies other users that a
FLASH SESSION IS IN-PROGRESS and must NOT be interrupted. Interrupting some flash
reprogramming sessions at critical junctures can render a module inoperative. Another user may
not realize that a flash session is in-progress and may disturb or disconnect the DRBIII(R) or do
something on the vehicle that could interrupt the flash process.
Before starting the flash session, read, record and erase all DTCs found on the vehicle.
Also "Cold Boot" the DRBIII(R) and download the flash since this will erase the flash file from the
DRBIII(R) memory. (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the
same time. Then press "F4").
Be sure to arrange the TechCONNECT and DRBIII(R) so that no cables are stretched across an
area where someone might trip over or kick a cable. When setting up your DRBIII(R), insure that it
rests on a surface where it will not fall or be bumped during reprogramming e.g.: DRBIII's have
been known to be swept off vehicle windshields by accident when a user bumps the wiper switch).
Check User settings on the DRBIII(R). From the DRBIII(R) Main menu, press 6,1 and check to
make sure item 1. Echo on PC is set to OFF. On occasion, when Echo on PC is set to ON, flash
reprogramming errors may occur.
VEHICLE BATTERY VOLTAGE
The flash programming procedure puts a load on the electrical system that may last from five to
twenty minutes depending on the particular flash reprogramming update. Connect a battery
charger to the vehicle. Set the charger to as close to 14 volts as possible. If the charger has a
timer, set it for 30 minutes BEFORE starting a flash reprogramming session. This will help to
prevent unwanted resets by either the DRBIII(R) and/or the vehicle module that are caused by
voltage fluctuations.
Alternately, as a bare minimum, use a "Battery Jump Box" when a battery charger is unavailable to
ensure adequate and stable system voltages on the module being flash reprogrammed.

Connected/Disconnected Flash Mode Using TechCONNECT
CONNECTED MODE FLASHING USING TechCONNECT
NOTE:
Capable but not recommended.
In this mode, the DRBIII(R) remains connected to the TechCONNECT Client and the vehicle
throughout the flash session. The DRBIII(R) is connected to the TechCONNECT Client using the
GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the CH7000A for most
vehicles).
This mode is useful when the TechCONNECT Client is next to the vehicle being flashed.
Another advantage of this mode is that you are able to determine all available flash updates for the
vehicle you are connected to by clicking on the "Read Part Number(s) From Vehicle" button.
Again, it is important that other users do not attempt to reboot or move the TechCONNECT Client
while a flash update is in-progress.
The reprogramming procedure of this mode is initiated by selecting the controller option and
clicking "Download/Update" button on the TechCONNECT client.
DISCONNECTED FLASH MODE
NOTE:
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3176
This is the preferred method.
This mode allows a user to flash a vehicle without being connected to the TechCONNECT Client.
This is a popular mode for flashing in a remote area of the service garage or in a back lot.
Before you attempt to use this mode, you must configure the DRBIII(R) for the desired update(s).
To do this, you must connect the DRBIII(R) to the TechCONNECT Client using the GPIB cable and
the CH7025 cable. It is not necessary to be connected to a vehicle. The GPIB (CH7035) cable will
be used to communicate with the TechCONNECT Client (for update file downloading) while the
CH7025 cable is used to provide power to the DRBIII(R).
After making the above connections, you are able to select one or more updates that you want to
perform. These selections are made by highlighting the desired updates and then clicking on the
"Download/Update" button by selecting the DRBIII(R) option on the TechCONNECT client.
Obviously, the DRBIII(R) does not have unlimited memory. If the file size of the selected updates
exceeds 948 KB, the "DRB Space Used" indicator (at the bottom-center of the TechCONNECT
Client screen) will change color from GREEN to RED. At this point you must de-select entries until
the indicator changes color to GREEN again.
When the updates have finished downloading, you may disconnect from the TechCONNECT Client
and take the DRBIII(R) to wherever the vehicle is located. The updates will remain in DRBIII(R)
memory for 8 hours while the DRBIII(R) is without power. If the DRBIII(R) is powered up for several
minutes before the 8 hour time period has expired, the update files will remain on the DRBIII(R) for
another 8 hours without power.
To start the actual flash process, after connecting to the vehicle in Disconnected Mode, you must
press "7 - Vehicle Flash" from the Main Menu on the DRBIII(R). Step by step instruction will follow
on the DRBIII(R) display. As with Connected Flash Mode, take the necessary precautions to insure
that others are aware of the flash session and that nothing disturbs the vehicle, DRBIII(R), or
cabling while performing the flash. Remember to use a battery charger set to 14 volts or a "battery
jump box".
Pay Attention While Performing Flash Reprogram Procedures
PAY ATTENTION WHILE PERFORMING FLASH REPROGRAMMING PROCEDURES
Before downloading the flash files, double check to see if the files that you have selected are the
appropriate ones for that vehicle. Don't forget about the "Read Part Numbers From Vehicle" option
on TechCONNECT Client, this can be of great assistance when trying to flash a module. If the files
selected don't download on the first attempt, try again.
The technician should NOT leave the vehicle when flash reprogramming a module.
Again, check to make sure that all cable connections are secure and that the DRBIII(R) rests on a
stable surface. If you are using a battery charger, insure that the settings and charging times are
correct and that the battery post clamps are securely fastened.
Read, record, and erase all DTCs found on the vehicle. Read and record the module type and part
number from the module that is to be flash reprogrammed.
Some control modules are not "abort-recovery" capable. When this is true, the scan tool will
indicate so by displaying a WARNING message prior to the start of reprogramming. For these
modules it is especially important that all precautions and procedures, outlined here, are carefully
followed.
Pay special attention to DRBIII(R) screen directions relating to key cycles. Missing a "Key ON" or
"Key OFF" can cause the module to have to be reflashed again. Due to the variety of module types
and vehicle options, you can't always anticipate key prompts, so be alert and ready to respond to
DRBIII(R) instructions.
Some screens will also instruct that certain modules, connectors or fuses be disconnected or pulled
prior to the start of reprogramming and re-installed immediately after completion. Be careful not to
anticipate the steps or order of operations for reprogramming any vehicle modules. Because of the
many possible changes that occur with each new release of scan tool software, always allow the
TSB/Recall and scan tool instructions to be your guide while performing flash reprogramming.
Flash reprogramming sessions usually range from 5 to 20 minutes. If the flash session has not
completed within 25 minutes after starting a flash reprogramming update, an error has most likely
occurred (Record the message that appears on the screen when a failure occurs). If this is the
case, or if you know that the flash process was interrupted, cycle the ignition key (OFF to the
locked position, then back ON). Reset the DRBIII(R) (power down for 4 seconds and then power
up) before attempting to restart the flash process. If the module still won't respond, turn the ignition
key off, disconnect the module from the vehicle for 2 minutes, reconnect the module, turn the
ignition key to run and try to restart the flash process again.
Regardless of what mode that you are in (Connected Flash or Disconnected Flash), if you have
tried twice (2 times) unsuccessfully to do a flash recovery and ALL DRBIII(R) instructions were
followed, perform the following:
^ Cold boot the DRBIII(R). This resets memory and removes all update files from the DRBIII(R).
(Push MORE and YES buttons at the same time, then press F4).
^ Reload the flash update file from the TechCONNECT Client.
^ If it fails to complete in the connected mode, first reboot the TechCONNECT Client before
re-attempting the flash download to the DRBIII(R).
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3177
^ Proceed to reflash the module.
On vehicles that have multiple flash updates available, always complete and verify each flash
update before attempting the next one.
After all flash reprogramming is completed, read and erase all DTCs in all modules on the vehicle.
A variety of DTCs may be set, which are usually related to a loss of communication with the
module(s) being reprogrammed.
Verify the update by reading the new part number using the DRBIII(R). A good double check is to
read the part number using DRBIII(R) stand alone.
At times, other modules, wired in parallel, to the DLC connector have prevented flash
reprogramming sessions to be successful. After the failed attempt, review the appropriate wiring
diagram for the vehicle you are flash reprogramming and, with the key "OFF"; disconnect the other
modules and retry the flash. Complete the flash, turn the key "OFF" and reconnect any modules
that were disconnected. Refer to the "Programmable Modules" section later in this document for
more information.
Error Messages
ERROR MESSAGES
Block Echo/Compare Errors
Block Echo and Block Compare errors are often caused by voltage fluctuations, faulty I/O cables
(CH7OOOA, CH7005, CH7010) or faulty communication connections at the diagnostic connector.
Inspect for these conditions and review the sections on Vehicle Battery Voltage and Cable
recommendations.
Checksum Errors
Checksum Errors are generally caused by corrupt flash update files, which can be caused by
DRBIII(R) memory problems. If the DRBIII(R) has been without power for more than 8 hours, the
update files and system memory could be in a corrupted state. "Cold Boot" the DRBIII(R). (To
"Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press
"F4"). Reload the flash update file(s) from the TechCONNECT CLIENT. If it fails to complete in the
connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to
the DRBIII(R). Then re-attempt the flash reprogramming process.
Enhanced and Original Abort Recovery
ENHANCED ABORT RECOVERY
Interruptions in the flash process are one of the main reasons for failed flash sessions and
non-responsive (NR) modules. Interrupting the flash process after the erase phase has started will
leave the control module in a non-functional state.
Generally, but not always, NR modules may be recovered successfully.
Briefly, abort recovery is the process used to get a NR module back to a fully functional state with
the latest software update. The technician should be familiar with the other sections in this
document and follow all DRBIII(R) user prompts carefully.
There are two methods for abort-recovery. The newer method is called "Enhanced Abort
Recovery". This is the preferred method since the original method takes several minutes longer
and requires the correct selection of module type from a list of possible PCM's or TCM's.
Starting with Release 60.1, a new useful feature was added to the flash reprogramming application
for Engine and Transmission control modules. The DRBIII(R) "writes" the YME and Controller Type
information to a "Safe Memory" location. This method allows for rapid recovery of the module part
number and minimizes errors that could otherwise be made by selecting the wrong controller type.
It also assumes that the user will attempt abort recovery for a failed flash attempt before moving to
another vehicle with the same DRBIII(R). If you need to move to another vehicle for flash
reprogramming you must erase the saved recovery information in order to successfully perform
flash reprogramming. Be careful to match the YME information displayed on the enhanced abort
recovery screen with the vehicle and module that you are attempting to recover. If you use the
recovery file on a different vehicle and module you could damage the module.
The recovery information will be displayed on your DRBIII(R), at the start of a flash session, only if
you previously encountered a problem that prevented a flash session from completing normally. If
your prior flash session was successful, the DRBIII(R) automatically erases the recovery file so that
the flash application will not show any recovery information at the start of your next flash session.
Enhanced abort recovery features:
^ Reduces the amount of time for the Module ID process.
^ Lowers the risk of possible user mistakes by presenting the user the Year, Model, Engine, and
Controller Type.
^ Currently only applicable to Engine and Transmission flash reprogramming.
^ The enhanced abort recovery file will only be erased upon a successful flash or manually by the
user.

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3178
^ Cold booting (simultaneously pushing MORE & YES, then F4) the DRBIII(R) will not erase the
enhanced abort recovery file, but cold booting the DRBIII(R) will still erase the flash file so it can be
reloaded.
^ The user has a choice, at the start of a flash session, whether or not to use the enhanced abort
recovery feature. If the user chooses to erase the recovery file, then the DRBIII(R) will use the
original method of abort recovery.
^ Cycling the ignition key, when prompted by the DRBIII(R), is still necessary to put the controller
into bootstrap (reprogramming) mode.
ORIGINAL ABORT RECOVERY
If the choice is made to use the original method of abort recovery, a NR module is not always able
to provide the DRBIII with ID information. In this case the technician must enter this when prompted
by the DRBIII(R). Be patient when performing this process. If the module does not respond to
standard diagnostic requests, the DRBIII(R) may take several minutes before it determines that the
engine module is in a NR state. At this point, the DRBIII(R) displays the prompt "Could not
determine engine controller type. Please select from list" along with a list of possible controller
types (if the DRBIII(R) is attempting to identify a TCM, the prompt will say "trans" instead of
"engine" and list the possible trans controller types). Because of module variations, it is important
to correctly identify the PCM/TCM type so that the correct flash procedure is used. Failure to do
this will cause further problems and may damage the module. Tables are provided below to help
identify the proper module type to select. These tables correctly identify the modules that were on
the vehicles when they were built. However, some vehicles will have module types which were
superseded to a new type when a replacement part was installed (ie: EATX4 modules replaced
with an EATX4A). Correctly identify these modules using DRBIII(R) Standalone prior to attempting
flash reprogramming.
NOTE:
When instructed to turn the key to the LOCKED position, be sure that the key is not just turned to
the OFF position. The key must be rotated to the point at which it can be removed from the ignition
switch. On most vehicles the switch is on the steering column and at this position the steering
column is LOCKED. When instructed to turn the key to the RUN position, be careful not to turn the
key past this position which may engage the starter motor. This creates electrical noise which
interferes with the flash process.
General Steps for Abort Recovery
1. Review all Tips and Techniques before continuing. Pay special attention to the section on
Preparing to Flash a controller and to the Programmable Modules section.
2. Cycle the vehicle's ignition key to the LOCKED position and back to the RUN position.
3. Reset the DRBIII(R) by disconnecting the vehicle cable from the DRBIII(R) for 4 seconds and
then reconnecting the cable.
4. Depending on where the flash session was aborted, the DRBIII(R) may require that the
technician identify the control module type that was being flash reprogrammed. Use the PCM/TCM
configuration table below as a guide. This step is not necessary if using the enhanced abort
recovery method.
5. After selecting the proper control module type or choosing enhanced abort recovery, follow the
prompts that are displayed on the DRBIII(R).
NOTE:
If an error message is displayed at this point, an incorrect module type was most likely selected. If
this occurs, start the process over.
6. If the recovery process is unsuccessful, perform the following:
a. Review the TSB/Recall notice (authorizing the flash update) and all Tips and Techniques in this
document.
b. Reboot/Restart the TechCONNECT Client.
c. "Cold Boot" the DRBIII(R). (Press the MORE and YES buttons on the DRBIII(R) at the same
time, then press F4).
d. Start this process over from item # 1. If using Disconnected Mode, the flash update will have to
be reloaded from the TechCONNECT Client or ISIS DVD.

Programmable Modules
The following pages list the various modules that have flash reprogramming capability. It does not
mean that a flash is currently available. What will be described are the module types and
variations, followed by items to note, and finally, abort recovery specifics if applicable.
Powertrain Modules - Engine and Transmission
ENGINE - POWERTRAIN CONTROL MODULE (PCM)
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3183
There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions that are
somewhat unique to each type will have comments. Prior to reprogramming a PCM, retrieve the
module information and module type using your DRBII I®. PCM information is used by many
modules. Be sure to check DIG's before and after performing all flash reprogramming event.
The DTC's associated with flash reprogramming generally relate to "lack of communication" with
the other modules during the reprogramming session.
SBEC
Types:
SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B
NOTE:
During recovery, if the DRBIII® is not seeing the key off, you may need to remove power (B+) to
PCM by removing fuse(s) or disconnecting the PCM. When DRBIII® states to turn key ON,
reconnect fuse or harness connection.
Abort Recovery Specifics:
^ Follow instructions on the DRBIII® for the module type. See table above.
^ Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not correctly
identify a key cycle. In this case a Modified Key Cycle routine is required.
This state is present when the following message is displayed on the DRBIII(R): "Can not read Part
Number. Did not see Key On or PCM/TCM Controller may not be flashable". When this occurs
restart the flash session and when prompted to turn the ignition key to the LOCKED position, pull
the fuse(s) that supply battery power to the module instead. When prompted to turn the key to the
RUN position, replace the battery supply fuse(s) instead.
JTEC
Types:
^ JTEC, JTEC+
NOTE:
Viper ALL - Roll down windows especially Coupes before attempting a flash.
NOTE:
1999 WJ JTEC with Speed Proportional Steering module. Disconnect before and reconnect after
the PCM flash reprogramming session. Also see Transmission.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
NGC Types:
^ NGC 1, NGC 2, and NGC 3
NOTE:
There are derivatives of NGC 3 that will be significant when reprogramming and or testing. NGC
modules use one of the longest time spans for flash reprogramming (approximately 15 minutes).
The NGCI and NGC3 controllers incorporate both an engine as well as a transmission controller in
a common package. The NGC2 controller incorporates the engine controller and an Electronic
Throttle Control (ETC) module in place of the TCM. All NGC controllers can be visually identified by
noting its four (4) wiring connectors. On manual transmission applications and the NGC2, only 3
connectors may be populated with pins.
NOTE:
On certain vehicles, the ABS CAB module connector MUST be disconnected prior to performing
this Repair Procedure. The CAB module and the PCM are connected at the same diagnostic
connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB module
connector, and reprogram the PCM per the Repair Procedure. When reprogramming is complete
turn the ignition switch to the OFF position, connect the CAB module connector, and then check for
DTC's. If the PCM becomes "locked" during reprogramming because the ABS CAB module
connector was not disconnected, then the PCM may be recovered by following the procedure in
this NOTE.

^ CM551 and CM84x series
NOTE:
Cummins flash reprogrammable PCMs are used on 1998.5 and newer Dodge Trucks.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully. Model Year 2000 and earlier vehicles have one Engine
Control Fuse to pull when prompted by the DRBIII(R). Model Year 2001 and later have two Engine
Control Fuses (one 20 Amp and one 30 Amp) to pull when prompted by the DRBIII(R). The fuse(s)
are located in the PDC and need to be pulled/removed, when prompted, for at least 10 seconds.
SIEMENS
Types:
^ SIM-70
NOTE:
The SIM-70 is currently used on BUX PL and PG vehicles with a 1.6L ONLY. Abort Recovery
Specifics:
Follow DRBIII(R) prompts carefully.
BOSCH
Types:
^ EDC15V, EDC15-C5, and EDC16
NOTE:
While there have been other Bosch modules, the EDC15V is not flash reprogrammable.
Transmission controllers are usually flashed on the vehicle (since 1996).
Technicians may set the pinion factor on "NEW" modules either before or after flash
reprogramming. Suggestions follow.
After flash reprogramming and before returning the vehicle to the customer, always perform a
"QuickLearn" to the TCM.
EATX
Types:
^ EATX, EATX 2, EATX 3, EATX 3A, EATX 3B, EATX 4, and EATX 4A
NOTE:
Table shows which TCM was installed "as-built". Often TCMs are superseded by parts and or a
service bulletin.
Abort Recovery Specifics:
^ 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement EATX4A part
numbers 56041814AD and 56028227AH currently display a P/N read failed error after the flash is
completed during PIN verification. This DOES NOT mean the flash failed. Check for the part
number using DRBIII(R) in standalone mode. This exists only for the service replacement modules
listed above. Flash reprogramming for OE modules flash and read the part number correctly.
Follow DRBIII(R) prompts carefully.

^ NGC1, NGC2, NGC3
NOTE:
The NGC I1and NGC 3 have the EATX/XCORE and Engine modules combined. NGC 2 does not.
Vehicles with automatic transmissions using NGC2 will use an EATX4A.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
^ 2002 DR, 2002.5 DN, 2003 AN/DN and later with NGC have shown that in some instances the
CAB controller may need to be disconnected when attempting to flash the NGC controller. (This
should only be performed if an error occurs at the very beginning of the TCM flash portion.)
SIEMENS
Types:
^ EG552
NOTE:
EGS52 is used with the A580 automatic transmission WG Grand Cherokees with a 2.7L diesel
engine (BUX), ZH Crossfire and VA Sprinter.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
JTEC
Types:
^ JTEC,JTEC+
NOTE:
Except for the 45RFE, 545RFE, and AW4 automatic transmissions, the JTEC controller also
provides transmission control functions on Dodge trucks and Jeep vehicles. Additionally, they are
used on some Cummins equipped Dodge trucks with manual and automatic transmissions.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
PRE 1996 EATX TRANSMISSION CONTROL MODULES
Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX controller
only to the PCM. Those vehicle TCMs only communicate to the DRBIII(R) using CCD
communications.
For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting those
modules to the DRBIII(R) vehicle connector.
For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because of this
you will need to use the Yellow SuperCard2, CH8361,to set pinion factor or when using a "new"
(superseded) TCM from parts as only the SuperCard2 properly sets the pinion factor on these
updated modules.
Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124.
The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin
18-24-95.
Types:
^ TCCM
NOTE:
These modules are found on AN, DN, and DR trucks.

NOTE:
THIS INFORMATION APPLIES TO NATURALLY ASPIRATED (NON-TURBO) GASOLINE
ENGINES.
DISCUSSION:
Some states that require I/M inspections are beginning to include OBD II "CARB" Readiness as a
prerequisite to an I/M test. OBD Readiness tells an I/M station if the OBD II systems have run their
self test. Owners, in those states that use OBD Readiness, may be denied an I/M test if one or
more of the Readiness monitors read "NO" or in other words the OBD II monitors have not run their
tests.
It is important to understand that the MIL will not be illuminated because OBD Readiness reads
"NO". MIL illumination happens when an actual malfunction or failure of a monitored emissions
system occurs. It is possible to have MIL illumination for a detected failure while at the same time
having a "NO" for an OBO Readiness monitor.
NOTE:
MIL ILLUMINATION INDICATES ADDITIONAL PROBLEMS WITH THE VEHICLE. FURTHER
DIAGNOSIS AND REPAIR WILL BE REQUIRED BEFORE PROCEEDING FURTHER WITH THIS
BULLETIN.
OBD Readiness that reads "NO" can be caused by the following: PCM reprogramming, PCM
replacement, fault code erasure, battery disconnects and/or replacement. If any of the above items
occur before an I/M test, a good chance exists that one or more of the monitors will read "NO" for
OBD Readiness.
Some customers may be directed back to their dealers for assistance when an I/M test station has
not allowed an I/M test due to Readiness status. The following procedures will help technicians
efficiently run the Readiness tests so an owner can have their I/M test completed.

Repair Procedure
This bulletin involves operating the vehicle under specific parameters to run or complete the OBD
monitors. The number of monitors applicable to a vehicle will vary by type of vehicle and emissions
application. In addition, the parameters to run each monitor will vary.
Preliminary Checks
1. Perform a MIL bulb check by switching the ignition key "ON" (engine off). The MIL will illuminate
as a bulb check. If the MIL does not illuminate, repair the bulb or bulb circuit.
2. Connect a DRB III(R) to the vehicle. Select DRB III(R) standalone, current model year
diagnostics, engine, DTC's and related functions, read DTC's.
3. Verity that no emission related DTC's are present and that the MIL is not illuminated with the
engine running.
NOTE:
EMISSION RELATED DTC'S AND MIL ILLUMINATION MAY PREVENT OTHER OBD MONITORS
FROM RUNNING. DTC'S THAT ILLUMINATE THE MIL MUST BE REPAIRED BEFORE
ATTEMPTING TO RUN THE MONITORS.
OBD "CARB" Readiness Check
1. With the DRB III(R) select engine, OBD II monitors, CARB Readiness Status.
2. Read the monitor status. "YES" tells you that monitor has run and is ready for an I/M test, "NO"
tells you that the monitor must be run. If all monitors listed read "YES", the vehicle can be returned
to the customer for completion of their I/M test. Only monitors that read "NO" must be run to read
"YES".
NOTE:
THE MONITORS LISTED IN THE OBD "CARB" READINESS SCREEN ARE THE ONLY ONES
APPLICABLE FOR THE VEHICLE BEING WORKED ON.
The vehicle must be operated in various conditions (speed, temperature, etc.) for the monitors to
run. Each monitor includes a pre-test and monitor test that can be viewed on the DRB III(R). The
pre-test/monitor test screen lists all the preliminary parameters that must be met along with the
running parameters for that specific monitor to run. An example of one screen is shown in Figure 1.

NOTE:
1997 AND PREVIOUS MODEL VEHICLES WILL HAVE A DIFFERENT LOOKING SCREEN.
PRESS THE F1 KEY TO OBTAIN MONITOR RUN CONDITIONS. THE WAY IN WHICH THE
MONITORS RUN WILL BE SIMILAR.
The following explains how to interpret each section of the screen:
PRE-TEST REQUIREMENTS
The pre-test requirements include all the operating parameters that must be met before the actual
test can run. The vehicle must be operated until each item within the pre-test section are fulfilled.
LOW VALUE/HIGH VALUE/BAR GRAPH
The low value/high value provides the minimum and maximum operating conditions for each item
(ie ECT Range must be between 170° and 260° F in Figure 1). The bar graph will begin to fill when
the lowest value required for each item is met. This provides a visual indication that the parameters
are being met. The vehicle should be driven until most of each pre-test bar graph is filled.
MONITOR REQUIREMENTS
Once all pre-test requirements are met, the vehicle must be brought within the parameters listed in
the monitor requirements section for the monitors to begin running. As the monitor begins to run,
the DRB III(R) will begin to beep. This is an audible indication that the test is in progress. If vehicle
operation falls outside any of the parameters, the beeping will stop. If this occurs, the technician
must determine if the pre-test requirements or the monitor requirements have fallen outside the
window for the test and the vehicle must be driven accordingly for the test to restart. When the
monitor completes its test, the DRB III(R) will beep 3 consecutive times.
NOTE:
THE PURGE FLOW PRE-TEST SCREEN WILL LOOK DIFFERENT THAN THE REST OF THE
PRE-TEST/MONITOR SCREENS. PRESS THE F1 KEY ON THE DRB III(R) TO SEE A SIMILAR
SCREEN FOR THIS MONITOR.
MONITOR RUN PROCESS
The following will provide the most efficient order along with tips to help run through the monitor
tests quickly. The monitors listed include all possible monitors for either Front Wheel Drive or Rear
Wheel Drive vehicles. The vehicle being worked on may have fewer monitors than the maximum
available. Only those listed on the DRB III(R) are applicable for the vehicle being worked on. The
only monitors that will require attention are those that read "NO" under the OBD "CARB"
Readiness Status screen.
Front Wheel Drive
1. Evaporative Leak Detection Monitor - This test will require a cold start (possibly an overnight
soak either indoors or out depending on conditions). The ambient (outside) temperature must be
between 4° and 32° C (40° and 90° F) with the engine coolant temperature within 6° C (10 ° F) of
ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen
on the DRB III(R) to determine the remaining requirements.
2. Catalyst Monitor - The vehicle must be driven at highway speeds for the time listed in the
pre-test screen. If the vehicle is equipped with a manual transaxle, use fourth gear to help meet the
requirements.
3. EGR Monitor - It is necessary to maintain TPS, MAP, and RPM ranges listed in the pre-test
screen for this test to complete.
4. O2 Sensor Monitor - The vehicle must be driven and brought to a stop for the time listed in the
pre-test screen. Automatic transaxle vehicles must be left in drive during the stop period.
5. Purge Monitor - To see a similar screen format as listed in Figure 1, press the F1 key on the
DRB III(R) while in the Purge Flow Pre-Test screen. The purge free (PF) cells must update and the
monitor will attempt to run on every other throttle closure. Automatic transaxle vehicles must be left
in drive for the test to run. If all parameters are met and the test still will not run, place your foot on
the brake, open the throttle to 1/4 and then quickly close the throttle. This should allow the PF cells
to update.
6. O2 Sensor Heater Monitor - The open throttle time for the O2 Heater pre-test must be exceeded.
This monitor will run after the ignition key is switched "Off". After the DRB III(R) switches to No
Response (approximately 3 minutes) turn the ignition key "On" and check the O2 Sensor Heater
monitor status. It should have switched to "YES". All other monitors should be completed before
running this test.
Rear Wheel Drive
1. O2 Sensor Heater Monitor - This test will require a cold start (possibly an overnight soak either
indoors or outdoors depending on conditions). The ambient (outside) temperature must be between
18° and 38° C (0° and 100° F with the engine coolant temperature within 6° C (10° F) of
ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen
on the DRB III(R) to determine the remaining

of ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test
screen on the DRB III(R) to determine the remaining requirements.
3. Catalyst Monitor - The vehicle must be driven at highway speeds for the time listed in the
pre-test screen. If the vehicle is equipped with a manual transmission, use 4th gear to help meet
the requirements.
4. O2 Sensor Monitor - The vehicle must be driven and brought to a stop for the time listed in the
pre-test screen. Automatic transmission vehicles must be left in drive during the stop period.
5. Purge Monitor - To see a similar screen format as listed in Figure 1, press the F1 key on the
DRB III(R) while in the Purge Flow Pre-Test screen. The purge free (PF) cells must update and the
monitor will attempt to run on every other throttle closure. Automatic transmission vehicles must be

THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH GASOLINE ENGINES AND A 42RE,
44RE, 46RE, OR 47RE TRANSMISSION.
SYMPTOM/CONDITION: At ambient temperatures of -20 C (-5 F) or below, the Powertrain Control
Module (PCM) will electronically inhibit the transmission from shifting into overdrive. This will
protect the transmission from damage if the transmission fluid begins to freeze. In extreme cold
climatic regions, this feature can cause customer dissatisfaction due to elimination of overdrive and
less than optimal fuel economy.
DIAGNOSIS: The cold weather by-pass kit along with disabling the inhibitor feature should only be
incorporated for vehicles used in areas of extended cold ambient temperatures.

Repair Procedure
This bulletin involves installing a cold weather by-pass kit to the transmission cooler circuit,
selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software
(calibration changes for 1996 models only), and using the DRB III to selectively turn off the
overdrive inhibitor feature for all applications.
NOTE:
IT IS ESSENTIAL THAT THE TRANSMISSION COOLER BYPASS KIT BE INSTALLED PRIOR
TO DISABLING THE INHIBITOR FEATURE. TRANSMISSION DAMAGE MAY OCCUR IF THE
BYPASS KIT IS NOT INSTALLED.
NOTE:
EVEN WITH BYPASS KIT INSTALLATION AND THE INHIBITOR FEATURE TURNED OFF, 4TH
GEAR WILL BE INHIBITED UNTIL THE OIL SUMP TEMPERATURE REACHES 0 C (30 F). THIS
MAY TAKE SEVERAL MINUTES.
Bypass Kit Installation
1. Record all radio pre-sets and disconnect the negative battery cable.
2. Raise the vehicle for access to the transmission housing. The bypass assembly will be
connected to the existing transmission lines and mounted to the transmission housing by means of
a bypass adapter.
3. During this installation procedure, some transmission fluid will be lost when the transmission
cooler lines are cut (allowing bypass assembly installation). Take proper precautions and check
transmission fluid fill level upon completing the installation.
4. It the cold weather bypass kit has provision for an in-line temperature sensor, the threaded
"therm-o-well" (in the pressure "P" line of the kit) must be plugged with either the temperature
sensor from the existing transmission line or the standard pipe plug provided. Consequently, if the
vehicle being serviced is equipped with a temperature sensor (i.e., heavy duty BR truck), remove
the temperature sensor from the existing line by un-threading and install it in the "pressure" line
provided with the kit. Use Mopar Thread Sealant, p/n 04318044, to ensure a leak free seal.
5. Disconnect the pressure and return lines from the transmission housing fittings.
6. Remove and discard the fittings from the transmission housing.
7. Apply Mopar Thread Sealant, p/n 04318044, to the threaded bypass adapter (# 2 Figure 1).
8. Install the threaded bypass adapter securely into the front pressure port of the transmission
housing and torque to 17.6 Nm (13 ft. lbs.).
9. Make sure the snap ring and O-ring are properly installed in their respective grooves on the nose
of the bypass assembly block. Lubricate the O-ring with ATF.
10. Position the bypass assembly block such that the return port fitting "R" is pointed directly up
and the two other fittings are pointed forward.
11. Firmly press the male nose of the bypass assembly into the female body of the threaded
bypass adapter until it snaps into place. After snapping into place, the bypass assembly is
permanently attached to the adapter.
NOTE:
THE BYPASS ASSEMBLY CAN ROTATE INSIDE THE ADAPTER, AND REMOVAL OF THE
BLOCK FROM THE TRANSMISSION HOUSING (IF REQUIRED) CAN BE ACCOMPLISHED BY
UN-THREADING THE ADAPTER.
CAUTION:
IF FLUSHING THE BYPASS ASSEMBLY IS REQUIRED, IT MUST BE REMOVED FROM THE
TRANSMISSION HOUSING AND FORWARD FLUSHED ONLY. FAILING TO REMOVE THE
VALVE AND REVERSE FLUSHING WILL RESULT IN TRANSMISSION FAILURE BY PLUGGING
THE BYPASS VALVES INTERNAL ORIFICE AND DRAIN BACK VALVE.
12. Apply Mopar Thread Sealant, p/n 04318044, to the threaded end (transmission housing end) of
the compression fitting.
13. Install the threaded compression fitting securely into the rear return port of the transmission
housing and torque to 17.6 Nm (13 ft. lbs.).

14. Using a small tubing cutter, cut the existing pressure line at approximately 120 mm (5 in.) from
the transmission housing end. Repeat the procedure for the existing return line.
CAUTION:
AFTER CUTTING THE PRESSURE LINE, MARK IT WITH A PIECE OF TAPE FOR
IDENTIFICATION.
15. Identify the proper return line ("R" line) by using the marked labels attached to the tubes.
16. Connect the "R" line to the bypass assembly block and the rearward return port of the
transmission housing. Tighten the compression fitting finger tight, and then wrench tighten it an
additional 1/2 turn. Tighten the inverted flare nut to 6.78 Nm (60 in. lbs.).
17. Select the appropriate "RR" and "P" tubes for the application. Mixing or matching may be
required to provide the best routing for your

application.
18. Loosely connect the pressure line "P" to the pressure port fitting "P" on the bypass assembly
block.
19. Loosely connect the radiator return line, "RR" to the "RR" port fitting, on the bypass assembly
block.
NOTE:
DURING THE INSTALLATION OF THE "P" AND "RR" LINES, THE ORDER MAY BE REVERSED
TO AID IN THE ASSEMBLY PROCESS.
NOTE:
ON 5.2L ZJ MODELS, THE THROTTLE VALVE CABLE AND BRACKET MAY REQUIRE
REMOVAL FOR BYPASS TUBE CLEARANCE. ONCE THE TUBES ARE INSTALLED LOOSELY,
INSTALL THE BRACKET AND THROTTLE VALVE CABLE. MAKE ANY ADJUSTMENTS FOR
CLEARANCE AND TIGHTEN THE BYPASS TUBES AND BRACKET ASSEMBLY.
20. Make sure that the existing return line is properly re-attached to the hanger bracket and lay the
new return line, "RR", beside it.
21. Install the hose bracket (# 12 in Figure 1) required for the overhead line application. The
bracket will replace the existing bracket at the starter mount location. It may require slight
modification to provide the best clearance from the exhaust system.
22. Attach clamp (# 11 in Figure 1) and the rubber hose to the "RR" tube to determine the
approximate rubber hose routing. For connection to the existing return line, the line may be cut
again to provide optimum line routing.
CAUTION:
WHEN ROUTING THE TUBING AND HOSE BE AWARE OF POTENTIAL MOVING
COMPONENT INTERFERENCES, SUCH AS THE PROPELLER SHAFT, SHIFT LINKAGE IN ALL
POSITIONS, TV CABLE, TV RETURN SPRING, AND TV LINKAGE. BE AWARE OF THE
EXHAUST SYSTEM, ALL ROUTINGS SHOULD MAINTAIN AT LEAST ONE INCH OF
CLEARANCE FROM THE EXHAUST SYSTEM.
23. Cut the rubber hose so that it has sufficient length to be attached to the existing return line.
24. Loosely connect a nut (# 7 in Figure 1), a compression sleeve (# 8 in Figure 1), and a hose
fitting (# 10 in Figure 1) to the existing return line.
25. Using a clamp (# 11 in Figure 1), install the rubber hose onto the hose fitting (# 10 in Figure 1).
26. Evaluate the line routing to ensure moving components and exhaust will not interfere with the
new lines. Make modifications as necessary to provide the best routing.
27. Disconnect the "RR" tube from the Bypass Block for access to the "P" port on the block
assembly.
28. Attach a clamp and the rubber hose to the "P" tube and determine the approximate rubber hose
routing. For connection to the existing pressure line, the line may be cut again to provide optimum
line routing.
CAUTION:
WHEN ROUTING THE TUBING AND HOSE BE AWARE OF POTENTIAL MOVING
COMPONENT INTERFERENCES, SUCH AS THE PROPELLER SHAFT, SHIFT LINKAGE IN ALL
POSITIONS, TV CABLE, TV RETURN SPRING, AND TV LINKAGE. BE AWARE OF THE
EXHAUST SYSTEM, ALL ROUTINGS SHOULD MAINTAIN AT LEAST ONE INCH OF
CLEARANCE FROM THE EXHAUST SYSTEM.
29. Cut the rubber hose so that it has sufficient length to be attached to the existing pressure line.
30. Loosely connect a nut (# 7 in Figure 1), a compression sleeve (# 8 in Figure 1), and a hose
fitting (# 10 in Figure 1) to the existing pressure line.
31. Using a clamp (# 11 in Figure 1), install the rubber hose onto the hose fitting (# 10 in Figure 1).
32. Evaluate the line routing to ensure moving components and exhaust will not interfere with the
new lines. Use tie straps and rubber bumpers on the hose to protect the hose from metal surfaces
that may cause chaffing.
33. Torque both clamps, the compression fitting (finger tight, then wrench tighten 1/2 turn), and the
inverted flare nut to 6.78 Nm (60 in. lbs.) on the "P" line.
34. Connect the "RR" ling and torque both clamps, the compression fitting (finger tight, then wrench
tighten 1/2 turn), and the inverted flare nut to 6.78 Nm (60 in. lbs.) on the "P" line.
35. Re-check to ensure that all connections have been securely tightened and there is sufficient
clearance around the exhaust system.
36. If applicable, connect the wire harness to the temperature sensor.

DISCUSSION:
NOTE:
Many of the reasons a flash reprogramming procedure may not complete are documented in this
service bulletin, but if you are constantly having issues performing the flash reprogramming
procedure using a specific DRBIII(R), it is suggested you send the DRBIII(R) in question to
SPX/Miller Special Tools for service.
Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment
may lock up or become disconnected during the procedure. Flash Reprogramming is a "CRITICAL
PROCESS"; an error may result in a no-start/failed control module. Most modules, encountering an
interruption or failure while reprogramming, are recoverable; a recoverable module is not covered
under the provisions of the warranty.
This service bulletin covers items that may cause this condition, a process to restart the flash
procedure, and miscellaneous information that will help prevent needless replacement of control
modules.
GENERAL: Flash Reprogramming is only authorized by a specific SERVICE BULLETIN, or
RECALL.
Review the entire Service Bulletin/Recall prior to performing a flash reprogramming update. Often
other parts may need to be serviced, replaced, or tested, prior to flash reprogramming, and ARE
REQUIRED as part of completing the Service Bulletin/Recall.
When flashing a Powertrain Control Module (PCM) or Transmission Control Module (TCM) there
are other legal requirements with labeling issues that are included in those service bulletins.
Other non-emission related modules, such as instrument clusters and Body Control Modules
(BCMs) do not require labels.
FLASH REPROGRAMMING SEQUENCE OF EVENTS
The process of flash reprogramming is similar to flashing the BIOS on a Personal Computer.
Interruptions, voltage problems, and a variety of other outside interactions can potentially interfere
with the process. This document seeks to provide information to minimize problems associated
with vehicle control module flash reprogramming. The description that follows is for most PCMs
and some TCMs. Other modules use different initiation procedures.
The process starts by selecting an update from the TechCONNECT Client or ISIS and then
"loading" that update into the DRBIII(R). Once the flash reprogramming update is loaded into the
DRBIII(R), and before the flash reprogramming begins, the DRBIII(R) verifies that the update
loaded from the TechCONNECT Client or ISIS is the proper update for the module. This is done
using part number supersedence. This verification occurs only if an update is required, available
(on the TechCONNECT Client or ISIS) and has been selected for programming.
^ The module is then placed into "Boot Strap" programming mode by the DRBIII(R). This module
mode gives the DRBIII(R) permission and the ability to proceed with the flash reprogramming
session.
^ Next, the current part number, which resides in the module's flash memory, is stored in a "Safe
Memory" location within the module. This memory location is not affected by flash memory erasure
and reprogramming, which are to follow.
^ Once the part number is safely stored, the flash memory in the control module is erased. From
this point forward any interruption in the flash process,

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3237
will result in a Non-Responsive module (NR). A NR module is a module that is either partially
erased or partially programmed.
^ After erasure, the actual reprogramming procedure starts, and the update software is
programmed into the flash memory within the module.
^ When reprogramming is completed, the flash memory is verified through an internal process in
the DRBIII(R) using a "Check Sum". This value is compared against another value that represents
what should be in memory and when matched, verifies successful reprogramming.
^ Next, a DRBIII(R) prompt is displayed instructing that the ignition switch be turned OFF. The
module exits the "Boot Strap" mode when the switch is turned off.
^ After a slight pause, the DRBIII(R) will prompt for the ignition switch to be turned ON. The
DRBIII(R) then reads the new part number in flash memory (along with a new computer program
the new part number is placed into the module's memory). If the new part number matches the
expected part number, the flash reprogramming session has completed successfully.
SOFTWARE VERSIONS MUST BE CURRENT
Before attempting a flash reprogramming session using the TechCONNECT Client, make sure you
have the most current DRBIII(R) software installed.
To verify whether your DRBIII(R) software is current, check the upper right-hand corner of the
TechCONNECT Client screen for DRBIII(R) Available Version, DRBIII(R) Current Version.
Often, because of multiple DRBIII(R)s in the shop, not all will get updated on a timely manner. The
installed DRBIII(R) software version can generally be found at the bottom center of most screens.
Alternately the version can be checked by pressing 6, 2, 5 from the DRBIII(R) Main Menu and
comparing it to what is available from a current TechCONNECT Client as described above.
If the TechCONNECT Client is current and the DRBIII(R) is not, it may be due to the fact that the
TechCONNECT Client does not force DRBIII(R) updates for "minor" revisions. Changes and new
support are added to the Vehicle Flash application on "minor" revisions on a regular basis. This is
why your TechCONNECT Client and DRBIII(R) must have the LATEST software revisions
installed.
DO NOT PASS on the option for updating to a "minor" revision!
Major updates require the DRBIII(R) to be updated prior to allowing any flash programming.
DRBIII(R) CABLES
A NEW DRBIII(R) cable was released as an Essential Service Tool! CH7000A - 8 ft.
Cable, DRBIII(R) to OBDII (J1962) DLC Connector.
CH7000A is the required cable for ALL flash reprogramming. The older CH7000 cable can be used
for diagnostics ONLY. One (1) cable was shipped to all dealerships. Easily identified, the correct
cable has a RED connector, which plugs into the DRBIII(R).
The cable modification enhances the DRBIII(R) communication capabilities when dealing with the
flash requirements of certain controllers/ECUs affected in part by the recent changes in DLC
connector configurations.
The new cable is required for ALL flash reprogramming sessions, and can be used wherever the
previous CH700017001 cables were used.
While not recommended for flash reprogramming usage, if you require a longer cable, there is also
a 12-foot cable released under pin CH7001A
The production of the previous CH700017001 cables has ceased. All orders placed will be
superseded to part number CH7000A/CH7001A.

NOTE:
Consider all cables wear items. Always inspect for worn, damaged cables, connectors that are
damaged or do not lock securely, and all mating connections including checking for corrosion on
the pins. REPLACE ALL suspect cables. Do not use worn or damaged cables when flash
reprogramming.
Failure to use the new cable or to use a damaged cable often results in failed flash reprogramming
sessions.
The 2 door Sebring, Stratus, and Avenger coupes (supplied by MMC) generally use the CH7O1O
cable (Pre-OBDII MMC vehicles will use the CH7005 cable).
TechCONNECT CABLE (GPIB)
Replace any suspect GPIB cable.
The GPIB cable provides the connection between TechCONNECT Client and the DRBIII(R).
This cable is used by the TechCONNECT Client for vehicle part number reads and to send update
files to the DRBIII(R).
Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If
this cable becomes disconnected during a flash session, you may have to reload the update file
that you selected on the TechCONNECT Client.
TROUBLESHOOTING CONNECTIVITY OF THE DRBIII(R) UNIT TO THE TechCONNECT
APPLICATION.
1. Turn-on the power to the DRBIII(R) unit.
2. Select option 2 "Connect to TechCONNECT" and press Enter.
3. Attach the male mini D-shell amphenol GPIB connector of the new DRBIII(R) cable (part number
CH7035B) to the DRBIII(R) unit.
4. Insure that the larger female D-shell amphenol GPIB connector of the new DRBIII(R) cable is
properly attached to the male D-shell amphenol GPIB connector on the GPIB-USB-B protocol
converter, (part number CHGPIB-B).
5. Attach the USB cable from the GPIB-USB-B protocol converter to one of the USB ports on the
rear panel of the client CPU.
6. When the cable is attached to the USB port of the CPU for the first time, Windows 2000 will
detect the device and install software for it. Please wait for 25-30 seconds to complete the
installation.

ISIS NULL MODEM CABLE
Replace any suspect null modem cables.
International (ISIS), a PC-based CD program similar to TechCONNECT Client uses a null modem
cable for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for
loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes
disconnected during a flash download session, you will have to reload the update file or files.
GENERAL NOTES FOR CABLES AND VEHICLE CONNECTIONS
Consider ALL cables to be wear items.
Many successful dealers have dedicated cables devoted to "Flash ONLY".
Always have spare CH7000A, CH7010 and CH2002 GPIB or null modem cables available.
Inspect vehicle diagnostic connectors for potential problems that might cause communication
interruptions.
There are now clip repair kits available through teamPSE to replace the retaining clips for two of
these cables. To protect the DRBIII(R) from internal damage, the clips are designed to fail at above
25 lbs. of axial force. Kits are described in the table.
It is a good practice to discard cables that have damage to the pins, cuts, corrosion, or general
damage beyond the retaining clips.

These vehicles use MMC based modules. The CH8432 Supplemental Reprogramming Tool (SRT)
was shipped as a 2001 Essential Tool. The flash reprogramming update files will be downloaded
from TechCONNECT Client to the SRT for flash reprogramming sessions on these vehicles. Users
should closely follow the instructions that come with the tool. If the tool has not been initialized,
there is a known condition where it may take up to 5 or more attempts for it to fully initialize and
become functional.
NOTE:
Once it has successfully flashed, it is initialized and no further action is required.
PREPARING TO FLASH
It is highly recommended that a sign, or other process, be used that notifies other users that a
FLASH SESSION IS IN-PROGRESS and must NOT be interrupted. Interrupting some flash
reprogramming sessions at critical junctures can render a module inoperative. Another user may
not realize that a flash session is in-progress and may disturb or disconnect the DRBIII(R) or do
something on the vehicle that could interrupt the flash process.
Before starting the flash session, read, record and erase all DTCs found on the vehicle.
Also "Cold Boot" the DRBIII(R) and download the flash since this will erase the flash file from the
DRBIII(R) memory. (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the
same time. Then press "F4").
Be sure to arrange the TechCONNECT and DRBIII(R) so that no cables are stretched across an
area where someone might trip over or kick a cable. When setting up your DRBIII(R), insure that it
rests on a surface where it will not fall or be bumped during reprogramming e.g.: DRBIII's have
been known to be swept off vehicle windshields by accident when a user bumps the wiper switch).
Check User settings on the DRBIII(R). From the DRBIII(R) Main menu, press 6,1 and check to
make sure item 1. Echo on PC is set to OFF. On occasion, when Echo on PC is set to ON, flash
reprogramming errors may occur.
VEHICLE BATTERY VOLTAGE
The flash programming procedure puts a load on the electrical system that may last from five to
twenty minutes depending on the particular flash reprogramming update. Connect a battery
charger to the vehicle. Set the charger to as close to 14 volts as possible. If the charger has a
timer, set it for 30 minutes BEFORE starting a flash reprogramming session. This will help to
prevent unwanted resets by either the DRBIII(R) and/or the vehicle module that are caused by
voltage fluctuations.
Alternately, as a bare minimum, use a "Battery Jump Box" when a battery charger is unavailable to
ensure adequate and stable system voltages on the module being flash reprogrammed.
POLICY: Information Only

This bulletin is supplied as technical information only and is not an authorization for repair.
Connected/Disconnected Flash Mode Using TechCONNECT
CONNECTED MODE FLASHING USING TechCONNECT
NOTE:
Capable but not recommended.
In this mode, the DRBIII(R) remains connected to the TechCONNECT Client and the vehicle
throughout the flash session. The DRBIII(R) is connected to the TechCONNECT Client using the
GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the CH7000A for most
vehicles).
This mode is useful when the TechCONNECT Client is next to the vehicle being flashed.
Another advantage of this mode is that you are able to determine all available flash updates for the
vehicle you are connected to by clicking on the "Read Part Number(s) From Vehicle" button.
Again, it is important that other users do not attempt to reboot or move the TechCONNECT Client
while a flash update is in-progress.
The reprogramming procedure of this mode is initiated by selecting the controller option and
clicking "Download/Update" button on the TechCONNECT client.
DISCONNECTED FLASH MODE
NOTE:
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3241
This is the preferred method.
This mode allows a user to flash a vehicle without being connected to the TechCONNECT Client.
This is a popular mode for flashing in a remote area of the service garage or in a back lot.
Before you attempt to use this mode, you must configure the DRBIII(R) for the desired update(s).
To do this, you must connect the DRBIII(R) to the TechCONNECT Client using the GPIB cable and
the CH7025 cable. It is not necessary to be connected to a vehicle. The GPIB (CH7035) cable will
be used to communicate with the TechCONNECT Client (for update file downloading) while the
CH7025 cable is used to provide power to the DRBIII(R).
After making the above connections, you are able to select one or more updates that you want to
perform. These selections are made by highlighting the desired updates and then clicking on the
"Download/Update" button by selecting the DRBIII(R) option on the TechCONNECT client.
Obviously, the DRBIII(R) does not have unlimited memory. If the file size of the selected updates
exceeds 948 KB, the "DRB Space Used" indicator (at the bottom-center of the TechCONNECT
Client screen) will change color from GREEN to RED. At this point you must de-select entries until
the indicator changes color to GREEN again.
When the updates have finished downloading, you may disconnect from the TechCONNECT Client
and take the DRBIII(R) to wherever the vehicle is located. The updates will remain in DRBIII(R)
memory for 8 hours while the DRBIII(R) is without power. If the DRBIII(R) is powered up for several
minutes before the 8 hour time period has expired, the update files will remain on the DRBIII(R) for
another 8 hours without power.
To start the actual flash process, after connecting to the vehicle in Disconnected Mode, you must
press "7 - Vehicle Flash" from the Main Menu on the DRBIII(R). Step by step instruction will follow
on the DRBIII(R) display. As with Connected Flash Mode, take the necessary precautions to insure
that others are aware of the flash session and that nothing disturbs the vehicle, DRBIII(R), or
cabling while performing the flash. Remember to use a battery charger set to 14 volts or a "battery
jump box".
Pay Attention While Performing Flash Reprogram Procedures
PAY ATTENTION WHILE PERFORMING FLASH REPROGRAMMING PROCEDURES
Before downloading the flash files, double check to see if the files that you have selected are the
appropriate ones for that vehicle. Don't forget about the "Read Part Numbers From Vehicle" option
on TechCONNECT Client, this can be of great assistance when trying to flash a module. If the files
selected don't download on the first attempt, try again.
The technician should NOT leave the vehicle when flash reprogramming a module.
Again, check to make sure that all cable connections are secure and that the DRBIII(R) rests on a
stable surface. If you are using a battery charger, insure that the settings and charging times are
correct and that the battery post clamps are securely fastened.
Read, record, and erase all DTCs found on the vehicle. Read and record the module type and part
number from the module that is to be flash reprogrammed.
Some control modules are not "abort-recovery" capable. When this is true, the scan tool will
indicate so by displaying a WARNING message prior to the start of reprogramming. For these
modules it is especially important that all precautions and procedures, outlined here, are carefully
followed.
Pay special attention to DRBIII(R) screen directions relating to key cycles. Missing a "Key ON" or
"Key OFF" can cause the module to have to be reflashed again. Due to the variety of module types
and vehicle options, you can't always anticipate key prompts, so be alert and ready to respond to
DRBIII(R) instructions.
Some screens will also instruct that certain modules, connectors or fuses be disconnected or pulled
prior to the start of reprogramming and re-installed immediately after completion. Be careful not to
anticipate the steps or order of operations for reprogramming any vehicle modules. Because of the
many possible changes that occur with each new release of scan tool software, always allow the
TSB/Recall and scan tool instructions to be your guide while performing flash reprogramming.
Flash reprogramming sessions usually range from 5 to 20 minutes. If the flash session has not
completed within 25 minutes after starting a flash reprogramming update, an error has most likely
occurred (Record the message that appears on the screen when a failure occurs). If this is the
case, or if you know that the flash process was interrupted, cycle the ignition key (OFF to the
locked position, then back ON). Reset the DRBIII(R) (power down for 4 seconds and then power
up) before attempting to restart the flash process. If the module still won't respond, turn the ignition
key off, disconnect the module from the vehicle for 2 minutes, reconnect the module, turn the
ignition key to run and try to restart the flash process again.
Regardless of what mode that you are in (Connected Flash or Disconnected Flash), if you have
tried twice (2 times) unsuccessfully to do a flash recovery and ALL DRBIII(R) instructions were
followed, perform the following:
^ Cold boot the DRBIII(R). This resets memory and removes all update files from the DRBIII(R).
(Push MORE and YES buttons at the same time, then press F4).
^ Reload the flash update file from the TechCONNECT Client.
^ If it fails to complete in the connected mode, first reboot the TechCONNECT Client before
re-attempting the flash download to the DRBIII(R).

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3242
^ Proceed to reflash the module.
On vehicles that have multiple flash updates available, always complete and verify each flash
update before attempting the next one.
After all flash reprogramming is completed, read and erase all DTCs in all modules on the vehicle.
A variety of DTCs may be set, which are usually related to a loss of communication with the
module(s) being reprogrammed.
Verify the update by reading the new part number using the DRBIII(R). A good double check is to
read the part number using DRBIII(R) stand alone.
At times, other modules, wired in parallel, to the DLC connector have prevented flash
reprogramming sessions to be successful. After the failed attempt, review the appropriate wiring
diagram for the vehicle you are flash reprogramming and, with the key "OFF"; disconnect the other
modules and retry the flash. Complete the flash, turn the key "OFF" and reconnect any modules
that were disconnected. Refer to the "Programmable Modules" section later in this document for
more information.
Error Messages
ERROR MESSAGES
Block Echo/Compare Errors
Block Echo and Block Compare errors are often caused by voltage fluctuations, faulty I/O cables
(CH7OOOA, CH7005, CH7010) or faulty communication connections at the diagnostic connector.
Inspect for these conditions and review the sections on Vehicle Battery Voltage and Cable
recommendations.
Checksum Errors
Checksum Errors are generally caused by corrupt flash update files, which can be caused by
DRBIII(R) memory problems. If the DRBIII(R) has been without power for more than 8 hours, the
update files and system memory could be in a corrupted state. "Cold Boot" the DRBIII(R). (To
"Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press
"F4"). Reload the flash update file(s) from the TechCONNECT CLIENT. If it fails to complete in the
connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to
the DRBIII(R). Then re-attempt the flash reprogramming process.
Enhanced and Original Abort Recovery
ENHANCED ABORT RECOVERY
Interruptions in the flash process are one of the main reasons for failed flash sessions and
non-responsive (NR) modules. Interrupting the flash process after the erase phase has started will
leave the control module in a non-functional state.
Generally, but not always, NR modules may be recovered successfully.
Briefly, abort recovery is the process used to get a NR module back to a fully functional state with
the latest software update. The technician should be familiar with the other sections in this
document and follow all DRBIII(R) user prompts carefully.
There are two methods for abort-recovery. The newer method is called "Enhanced Abort
Recovery". This is the preferred method since the original method takes several minutes longer
and requires the correct selection of module type from a list of possible PCM's or TCM's.
Starting with Release 60.1, a new useful feature was added to the flash reprogramming application
for Engine and Transmission control modules. The DRBIII(R) "writes" the YME and Controller Type
information to a "Safe Memory" location. This method allows for rapid recovery of the module part
number and minimizes errors that could otherwise be made by selecting the wrong controller type.
It also assumes that the user will attempt abort recovery for a failed flash attempt before moving to
another vehicle with the same DRBIII(R). If you need to move to another vehicle for flash
reprogramming you must erase the saved recovery information in order to successfully perform
flash reprogramming. Be careful to match the YME information displayed on the enhanced abort
recovery screen with the vehicle and module that you are attempting to recover. If you use the
recovery file on a different vehicle and module you could damage the module.
The recovery information will be displayed on your DRBIII(R), at the start of a flash session, only if
you previously encountered a problem that prevented a flash session from completing normally. If
your prior flash session was successful, the DRBIII(R) automatically erases the recovery file so that
the flash application will not show any recovery information at the start of your next flash session.
Enhanced abort recovery features:
^ Reduces the amount of time for the Module ID process.
^ Lowers the risk of possible user mistakes by presenting the user the Year, Model, Engine, and
Controller Type.
^ Currently only applicable to Engine and Transmission flash reprogramming.
^ The enhanced abort recovery file will only be erased upon a successful flash or manually by the
user.

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3243
^ Cold booting (simultaneously pushing MORE & YES, then F4) the DRBIII(R) will not erase the
enhanced abort recovery file, but cold booting the DRBIII(R) will still erase the flash file so it can be
reloaded.
^ The user has a choice, at the start of a flash session, whether or not to use the enhanced abort
recovery feature. If the user chooses to erase the recovery file, then the DRBIII(R) will use the
original method of abort recovery.
^ Cycling the ignition key, when prompted by the DRBIII(R), is still necessary to put the controller
into bootstrap (reprogramming) mode.
ORIGINAL ABORT RECOVERY
If the choice is made to use the original method of abort recovery, a NR module is not always able
to provide the DRBIII with ID information. In this case the technician must enter this when prompted
by the DRBIII(R). Be patient when performing this process. If the module does not respond to
standard diagnostic requests, the DRBIII(R) may take several minutes before it determines that the
engine module is in a NR state. At this point, the DRBIII(R) displays the prompt "Could not
determine engine controller type. Please select from list" along with a list of possible controller
types (if the DRBIII(R) is attempting to identify a TCM, the prompt will say "trans" instead of
"engine" and list the possible trans controller types). Because of module variations, it is important
to correctly identify the PCM/TCM type so that the correct flash procedure is used. Failure to do
this will cause further problems and may damage the module. Tables are provided below to help
identify the proper module type to select. These tables correctly identify the modules that were on
the vehicles when they were built. However, some vehicles will have module types which were
superseded to a new type when a replacement part was installed (ie: EATX4 modules replaced
with an EATX4A). Correctly identify these modules using DRBIII(R) Standalone prior to attempting
flash reprogramming.
NOTE:
When instructed to turn the key to the LOCKED position, be sure that the key is not just turned to
the OFF position. The key must be rotated to the point at which it can be removed from the ignition
switch. On most vehicles the switch is on the steering column and at this position the steering
column is LOCKED. When instructed to turn the key to the RUN position, be careful not to turn the
key past this position which may engage the starter motor. This creates electrical noise which
interferes with the flash process.
General Steps for Abort Recovery
1. Review all Tips and Techniques before continuing. Pay special attention to the section on
Preparing to Flash a controller and to the Programmable Modules section.
2. Cycle the vehicle's ignition key to the LOCKED position and back to the RUN position.
3. Reset the DRBIII(R) by disconnecting the vehicle cable from the DRBIII(R) for 4 seconds and
then reconnecting the cable.
4. Depending on where the flash session was aborted, the DRBIII(R) may require that the
technician identify the control module type that was being flash reprogrammed. Use the PCM/TCM
configuration table below as a guide. This step is not necessary if using the enhanced abort
recovery method.
5. After selecting the proper control module type or choosing enhanced abort recovery, follow the
prompts that are displayed on the DRBIII(R).
NOTE:
If an error message is displayed at this point, an incorrect module type was most likely selected. If
this occurs, start the process over.
6. If the recovery process is unsuccessful, perform the following:
a. Review the TSB/Recall notice (authorizing the flash update) and all Tips and Techniques in this
document.
b. Reboot/Restart the TechCONNECT Client.
c. "Cold Boot" the DRBIII(R). (Press the MORE and YES buttons on the DRBIII(R) at the same
time, then press F4).
d. Start this process over from item # 1. If using Disconnected Mode, the flash update will have to
be reloaded from the TechCONNECT Client or ISIS DVD.

There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions that are
somewhat unique to each type will have comments. Prior to reprogramming a PCM, retrieve the
module information and module type using your DRBII I®. PCM information is used by many
modules. Be sure to check DIG's before and after performing all flash reprogramming event.
The DTC's associated with flash reprogramming generally relate to "lack of communication" with
the other modules during the reprogramming session.
SBEC
Types:
SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B
NOTE:
During recovery, if the DRBIII® is not seeing the key off, you may need to remove power (B+) to
PCM by removing fuse(s) or disconnecting the PCM. When DRBIII® states to turn key ON,
reconnect fuse or harness connection.
Abort Recovery Specifics:
^ Follow instructions on the DRBIII® for the module type. See table above.
^ Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not correctly
identify a key cycle. In this case a Modified Key Cycle routine is required.
This state is present when the following message is displayed on the DRBIII(R): "Can not read Part
Number. Did not see Key On or PCM/TCM Controller may not be flashable". When this occurs
restart the flash session and when prompted to turn the ignition key to the LOCKED position, pull
the fuse(s) that supply battery power to the module instead. When prompted to turn the key to the
RUN position, replace the battery supply fuse(s) instead.
JTEC
Types:
^ JTEC, JTEC+
NOTE:
Viper ALL - Roll down windows especially Coupes before attempting a flash.
NOTE:
1999 WJ JTEC with Speed Proportional Steering module. Disconnect before and reconnect after
the PCM flash reprogramming session. Also see Transmission.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
NGC Types:
^ NGC 1, NGC 2, and NGC 3
NOTE:
There are derivatives of NGC 3 that will be significant when reprogramming and or testing. NGC
modules use one of the longest time spans for flash reprogramming (approximately 15 minutes).
The NGCI and NGC3 controllers incorporate both an engine as well as a transmission controller in
a common package. The NGC2 controller incorporates the engine controller and an Electronic
Throttle Control (ETC) module in place of the TCM. All NGC controllers can be visually identified by
noting its four (4) wiring connectors. On manual transmission applications and the NGC2, only 3
connectors may be populated with pins.
NOTE:
On certain vehicles, the ABS CAB module connector MUST be disconnected prior to performing
this Repair Procedure. The CAB module and the PCM are connected at the same diagnostic
connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB module
connector, and reprogram the PCM per the Repair Procedure. When reprogramming is complete
turn the ignition switch to the OFF position, connect the CAB module connector, and then check for
DTC's. If the PCM becomes "locked" during reprogramming because the ABS CAB module
connector was not disconnected, then the PCM may be recovered by following the procedure in
this NOTE.

CUMMINS
Types:
^ CM551 and CM84x series
NOTE:
Cummins flash reprogrammable PCMs are used on 1998.5 and newer Dodge Trucks.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully. Model Year 2000 and earlier vehicles have one Engine
Control Fuse to pull when prompted by the DRBIII(R). Model Year 2001 and later have two Engine
Control Fuses (one 20 Amp and one 30 Amp) to pull when prompted by the DRBIII(R). The fuse(s)
are located in the PDC and need to be pulled/removed, when prompted, for at least 10 seconds.
SIEMENS
Types:
^ SIM-70
NOTE:
The SIM-70 is currently used on BUX PL and PG vehicles with a 1.6L ONLY. Abort Recovery
Specifics:
Follow DRBIII(R) prompts carefully.
BOSCH
Types:
^ EDC15V, EDC15-C5, and EDC16
NOTE:
While there have been other Bosch modules, the EDC15V is not flash reprogrammable.
Transmission controllers are usually flashed on the vehicle (since 1996).
Technicians may set the pinion factor on "NEW" modules either before or after flash
reprogramming. Suggestions follow.
After flash reprogramming and before returning the vehicle to the customer, always perform a
"QuickLearn" to the TCM.
EATX
Types:
^ EATX, EATX 2, EATX 3, EATX 3A, EATX 3B, EATX 4, and EATX 4A
NOTE:
Table shows which TCM was installed "as-built". Often TCMs are superseded by parts and or a
service bulletin.
Abort Recovery Specifics:
^ 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement EATX4A part
numbers 56041814AD and 56028227AH currently display a P/N read failed error after the flash is
completed during PIN verification. This DOES NOT mean the flash failed. Check for the part
number using DRBIII(R) in standalone mode. This exists only for the service replacement modules
listed above. Flash reprogramming for OE modules flash and read the part number correctly.
Follow DRBIII(R) prompts carefully.
NGC

^ NGC1, NGC2, NGC3
NOTE:
The NGC I1and NGC 3 have the EATX/XCORE and Engine modules combined. NGC 2 does not.
Vehicles with automatic transmissions using NGC2 will use an EATX4A.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
^ 2002 DR, 2002.5 DN, 2003 AN/DN and later with NGC have shown that in some instances the
CAB controller may need to be disconnected when attempting to flash the NGC controller. (This
should only be performed if an error occurs at the very beginning of the TCM flash portion.)
SIEMENS
Types:
^ EG552
NOTE:
EGS52 is used with the A580 automatic transmission WG Grand Cherokees with a 2.7L diesel
engine (BUX), ZH Crossfire and VA Sprinter.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
JTEC
Types:
^ JTEC,JTEC+
NOTE:
Except for the 45RFE, 545RFE, and AW4 automatic transmissions, the JTEC controller also
provides transmission control functions on Dodge trucks and Jeep vehicles. Additionally, they are
used on some Cummins equipped Dodge trucks with manual and automatic transmissions.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
PRE 1996 EATX TRANSMISSION CONTROL MODULES
Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX controller
only to the PCM. Those vehicle TCMs only communicate to the DRBIII(R) using CCD
communications.
For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting those
modules to the DRBIII(R) vehicle connector.
For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because of this
you will need to use the Yellow SuperCard2, CH8361,to set pinion factor or when using a "new"
(superseded) TCM from parts as only the SuperCard2 properly sets the pinion factor on these
updated modules.
Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124.
The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin
18-24-95.

Owner Letter
EMISSIONS RECALL TO REPROGRAM YOUR VEHICLE'S POWERTRAIN CONTROL MODULE
Dear DaimlerChrysler Vehicle Owner:
DaimlerChrysler has determined that some 1998 Dodge Dakota, Durango, Ram Van/Wagon, Ram
Truck, and Jeep(R) Grand Cherokee vehicles, equipped with a V-8 or V-10 engine, may be in
violation of California Emissions Regulations.
The problem is...
The On-Board Diagnostic (OBD) system on your vehicle (identified on the enclosed form) may not
detect evaporative emissions purge system malfunctions as required by California Emissions
Regulations. As a result, the OBD system on your vehicle may not illuminate the "Check Engine"
light if the evaporative emissions purge system malfunctions. This could cause your vehicle to emit
hydrocarbon levels above the limits that were established to protect the public health from the
dangers of air pollution.
Hydrocarbons (unburned fuel) combined with oxides of nitrogen, in the presence of sunlight, can
cause the formation of ozone. These pollutants are the primary components of smog.
What DaimlerChrysler and your dealer will do...
DaimlerChrysler will repair your vehicle free of charge (parts and labor). To do this, your dealer will
reprogram your vehicle's powertrain control module. The work will take about 1/2 hour to complete.
However, additional time may be necessary depending on how dealer appointments are scheduled
and processed.
What you must do...
^ Simply contact your dealer right away to schedule a service appointment.
^ Bring the enclosed Owner Notification form with you to your dealer. It identifies the required
service to the dealer.
If you live in California and don't get this done...
The State of California requires the completion of emission recall repairs prior to vehicle
registration renewal. In addition, the State requires that every vehicle must pass an emission test
(SMOG Check) every two years and before it is sold. Without the free service we are providing,
your vehicle may be more likely to fail this test and require that you make costly repairs.
How the state knows that the recall has been performed...
State of California regulations require DaimlerChrysler to provide the Department of Motor Vehicles
with a record of all vehicles that have not had the recall service performed. If you live in the state of
California and your vehicle is not on this list, the state will know that the recall has been completed.
Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the
recall service is completed. Be sure to save this form since the California Department of Motor
Vehicles may require that you supply it as proof of recall completion.
If you need help...
If you have trouble getting your vehicle repaired, please call the DaimlerChrysler Customer
Assistance Center, toll free, at 1-800-992-1997. A representative will assist you in getting your
vehicle repaired.
In order to ensure your full protection under the emission warranty provisions, it is recommended
that you have your vehicle serviced as soon as possible. Failure to do so could be determined as
lack of proper maintenance of your vehicle.
We are sorry for any inconvenience but trust you understand our interest in clean air and your
continued satisfaction with our products. Thank you for your attention to this important matter.

NUMBER: 21-08-99
GROUP: Transmission
DATE: April 30, 1999
SUBJECT: "Buzz", "Whining", Or "Moaning" Like Noise From A Cold Transmission When Reverse
Is Selected.
OVERVIEW: This bulletin involves replacing the transmission regulator valve.
MODELS: 1996 - 1999
(AB) Ram Van
1996 - 1999 (AN) Dakota
1996 - 1999 (BR/BE) Ram Truck
1998 - 1999 (DN) Durango

1996 - 1998 (ZJ) Grand Cherokee
1999 (WJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC
TRANSMISSION.
SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission
when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning"
like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100
F.). The condition is caused by a resonance of the transmission regulator valve system.
Other items may cause regulator valve resonance, including air ingestion into the valve body or out
of specification parts. These two items may be the result a possible cracked pump housing, a torn
pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of
specification valve and/or valve body. You should remember these additional items / components
when you perform your diagnosis.
Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve
body or an entire automatic transmission was replaced with components manufactured after
August 1, 1995.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual,
verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble
Codes (DTC's) are present, record them on the repair order and repair as necessary before
proceeding further with this bulletin.
For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to
determine if it applies to this vehicle before attempting to complete the analysis or repairs
described in this bulletin.
In most instances, the sump temperature of vehicles exhibiting transmission regulator valve
resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to
remain parked in a cool place overnight. Then perform the following steps:
1. Set the vehicle parking brake.
2. Start the engine (make certain windows are closed, to eliminate outside noise).
3. With brakes applied, place the transmission selector lever in reverse.
4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to
normal operating temperature (180 - 210 degrees F).
5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too
High
OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain
Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and
99Cal14).
MODELS:
**1996** - 1999 (AB) Ram Van
**1996** - 1999 (AN) Dakota
**1996** - 1999 (BR/BE) Ram Truck
1998 - 1999 (DN) Durango
**1997** - 1999 (TJ) Wrangler
**1996** 1999 (XJ) Cherokee
**1996** - 1998 (ZJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC
TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX).
SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble
Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle
operator may experience slower than normal vehicle accelerations because the transmission may
have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode
may last until the vehicle owner cycles the ignition key. The technician may not detect a problem
with the automatic transmission during a diagnostic test or test drive.
The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the
result of a new valve body machining process, which entered into production January 1, 1998. This
condition will occur most often with vehicles that were built between January 1, 1998 and
December 18, 1998.
Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the
transmission assembly is replaced with components built after January 1, 1998.
DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB
III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission
systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record
them on the repair order and repair as necessary before proceeding further with this bulletin. If no
DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF
THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION
LEVEL. USE THE FLASH PROCEDURE TO UPDATE REPLACED CONTROLLERS AS
NECESSARY.

1996 - 1998 (ZJ) Grand Cherokee
1999 (WJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC
TRANSMISSION.
SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission
when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning"
like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100
F.). The condition is caused by a resonance of the transmission regulator valve system.
Other items may cause regulator valve resonance, including air ingestion into the valve body or out
of specification parts. These two items may be the result a possible cracked pump housing, a torn
pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of
specification valve and/or valve body. You should remember these additional items / components
when you perform your diagnosis.
Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve
body or an entire automatic transmission was replaced with components manufactured after
August 1, 1995.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual,
verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble
Codes (DTC's) are present, record them on the repair order and repair as necessary before
proceeding further with this bulletin.
For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to
determine if it applies to this vehicle before attempting to complete the analysis or repairs
described in this bulletin.
In most instances, the sump temperature of vehicles exhibiting transmission regulator valve
resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to
remain parked in a cool place overnight. Then perform the following steps:
1. Set the vehicle parking brake.
2. Start the engine (make certain windows are closed, to eliminate outside noise).
3. With brakes applied, place the transmission selector lever in reverse.
4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to
normal operating temperature (180 - 210 degrees F).
5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

FLUID COLOR
Mopar ATF+4(R) has exceptional durability. However, the red dye used in ATF+4(R) is not
permanent; as the fluid ages it may become darker or appear brown in color. ATF+4(R) also has a
unique odor that may change with age. With ATF+4(R) fluid, color and odor are no longer
indicators of fluid condition and do not necessarily support a fluid change.

NOTE:
THIS INFORMATION APPLIES TO VEHICLES BUILT BEFORE JAN 16, 1998 MDH (0116XX)
EQUIPPED WITH GASOLINE ENGINES AND A 42/44/46 OR 47RE TRANSMISSION.
SYMPTOM/CONDITION:
Some vehicles may experience bucking during wide open throttle (WOT) acceleration. The bucking
occurs at approximately 5300 RPM. This condition may be caused by reaching the high RPM fuel
shut off rev limit before the transmission can shift into the next higher gear and is most likely to
occur with high electrical loads (high beams on, heated back lite, heated seats, radio, HVAC blower
on MAX etc.). During high current demands, the generator may emit electrical noise that can affect
the transmission governor pressure sensor output. If this occurs, the transmission may not shift
properly to the next higher gear under (WOT) acceleration conditions and therefore reach the fuel
shut off rev limiter. This may be seen most often between the 2-3 shift but can also be experienced
between the 1-2 shift.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual,
verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes
(DTC's) are present, record them on the repair order and repair as necessary before proceeding
further with this bulletin.
NOTE:
ONLY PERFORM THE FOLLOWING PROCEDURE SAFELY ON A HIGHWAY OR ROAD
OBEYING ALL POSTED SPEED LIMITS AND LAWS.
Attempt to duplicate the condition by switching on all accessory loads and driving the vehicle with
WOT accelerations through a shift sequence to see if the engine will reach the fuel shut off rev
limiter before the 2-3 or 1-2 shift is made.
If the bucking condition is experienced at approximately 5300 RPM before making the appropriate
upshifts, switch off all electrical loads and repeat the procedure. Repeat the procedure with the
electrical loads on and off a second time. If the bucking occurs with the electrical loads on and
does not occur with the loads off, perform the Repair Procedure.

1999, WHICH SHOULD BE REMOVED FROM YOUR FILES. ALL REVISIONS ARE
HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS.
SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too
High
OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain
Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and
99Cal14).
MODELS:
**1996** - 1999 (AB) Ram Van
**1996** - 1999 (AN) Dakota
**1996** - 1999 (BR/BE) Ram Truck
1998 - 1999 (DN) Durango
**1997** - 1999 (TJ) Wrangler
**1996** 1999 (XJ) Cherokee
**1996** - 1998 (ZJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC
TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX).
SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble
Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle
operator may experience slower than normal vehicle accelerations because the transmission may
have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode
may last until the vehicle owner cycles the ignition key. The technician may not detect a problem
with the automatic transmission during a diagnostic test or test drive.
The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the
result of a new valve body machining process, which entered into production January 1, 1998. This
condition will occur most often with vehicles that were built between January 1, 1998 and
December 18, 1998.
Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the
transmission assembly is replaced with components built after January 1, 1998.
DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB
III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission
systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record
them on the repair order and repair as necessary before proceeding further with this bulletin. If no
DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF
THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION
LEVEL. USE THE FLASH PROCEDURE TO UPDATE REPLACED CONTROLLERS AS
NECESSARY.

EQUIPPED WITH GASOLINE ENGINES AND A 42/44/46 OR 47RE TRANSMISSION.
SYMPTOM/CONDITION:
Some vehicles may experience bucking during wide open throttle (WOT) acceleration. The bucking
occurs at approximately 5300 RPM. This condition may be caused by reaching the high RPM fuel
shut off rev limit before the transmission can shift into the next higher gear and is most likely to
occur with high electrical loads (high beams on, heated back lite, heated seats, radio, HVAC blower
on MAX etc.). During high current demands, the generator may emit electrical noise that can affect
the transmission governor pressure sensor output. If this occurs, the transmission may not shift
properly to the next higher gear under (WOT) acceleration conditions and therefore reach the fuel
shut off rev limiter. This may be seen most often between the 2-3 shift but can also be experienced
between the 1-2 shift.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual,
verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes
(DTC's) are present, record them on the repair order and repair as necessary before proceeding
further with this bulletin.
NOTE:
ONLY PERFORM THE FOLLOWING PROCEDURE SAFELY ON A HIGHWAY OR ROAD

Attempt to duplicate the condition by switching on all accessory loads and driving the vehicle with
WOT accelerations through a shift sequence to see if the engine will reach the fuel shut off rev
limiter before the 2-3 or 1-2 shift is made.
If the bucking condition is experienced at approximately 5300 RPM before making the appropriate
upshifts, switch off all electrical loads and repeat the procedure. Repeat the procedure with the
electrical loads on and off a second time. If the bucking occurs with the electrical loads on and
does not occur with the loads off, perform the Repair Procedure.

Overdrive Indicator Lamp: Description and Operation
SYSTEM OPERATION
The overdrive-off indicator lamp gives the driver an indication that the automatic transmission
overdrive has been locked out. The lamp is controlled by the Powertrain Control Module (PCM) on
a hard wired circuit to instrument cluster.
The PCM receives an input from the momentary overdrive lockout switch, which is located on the
end of the automatic transmission gearshift selector lever. The PCM uses the overdrive lockout
switch input, along with numerous other sensor inputs and its internal programming to decide
whether the over-drive-off indicator lamp should be on or off. The PCM then turns the lamp on or
off by controlling the ground path for the lamp control circuit.

NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC
TRANSMISSION.
SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission
when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning"
like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100
F.). The condition is caused by a resonance of the transmission regulator valve system.
Other items may cause regulator valve resonance, including air ingestion into the valve body or out
of specification parts. These two items may be the result a possible cracked pump housing, a torn
pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of
specification valve and/or valve body. You should remember these additional items / components
when you perform your diagnosis.
Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve
body or an entire automatic transmission was replaced with components manufactured after
August 1, 1995.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual,
verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble
Codes (DTC's) are present, record them on the repair order and repair as necessary before
proceeding further with this bulletin.
For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to
determine if it applies to this vehicle before attempting to complete the analysis or repairs
described in this bulletin.
In most instances, the sump temperature of vehicles exhibiting transmission regulator valve
resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to
remain parked in a cool place overnight. Then perform the following steps:
1. Set the vehicle parking brake.
2. Start the engine (make certain windows are closed, to eliminate outside noise).
3. With brakes applied, place the transmission selector lever in reverse.
4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to
normal operating temperature (180 - 210 degrees F).
5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too
High
OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain
Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and
99Cal14).
MODELS:
**1996** - 1999 (AB) Ram Van
**1996** - 1999 (AN) Dakota
**1996** - 1999 (BR/BE) Ram Truck
1998 - 1999 (DN) Durango
**1997** - 1999 (TJ) Wrangler
**1996** 1999 (XJ) Cherokee
**1996** - 1998 (ZJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC
TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX).
SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble
Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle
operator may experience slower than normal vehicle accelerations because the transmission may
have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode
may last until the vehicle owner cycles the ignition key. The technician may not detect a problem
with the automatic transmission during a diagnostic test or test drive.
The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the
result of a new valve body machining process, which entered into production January 1, 1998. This
condition will occur most often with vehicles that were built between January 1, 1998 and
December 18, 1998.
Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the
transmission assembly is replaced with components built after January 1, 1998.
DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB
III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission
systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record
them on the repair order and repair as necessary before proceeding further with this bulletin. If no
DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF
THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION
LEVEL. USE THE FLASH PROCEDURE TO UPDATE REPLACED CONTROLLERS AS
NECESSARY.

SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too
High
OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain
Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and
99Cal14).
MODELS:
**1996** - 1999 (AB) Ram Van
**1996** - 1999 (AN) Dakota
**1996** - 1999 (BR/BE) Ram Truck
1998 - 1999 (DN) Durango
**1997** - 1999 (TJ) Wrangler
**1996** 1999 (XJ) Cherokee
**1996** - 1998 (ZJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC
TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX).
SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble
Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle
operator may experience slower than normal vehicle accelerations because the transmission may
have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode
may last until the vehicle owner cycles the ignition key. The technician may not detect a problem
with the automatic transmission during a diagnostic test or test drive.
The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the
result of a new valve body machining process, which entered into production January 1, 1998. This
condition will occur most often with vehicles that were built between January 1, 1998 and
December 18, 1998.
Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the
transmission assembly is replaced with components built after January 1, 1998.
DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB
III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission
systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record
them on the repair order and repair as necessary before proceeding further with this bulletin. If no
DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF
THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION
LEVEL. USE THE FLASH PROCEDURE TO UPDATE REPLACED CONTROLLERS AS
NECESSARY.

NOTE:
THIS INFORMATION APPLIES TO VEHICLES BUILT BEFORE JAN 16, 1998 MDH (0116XX)
EQUIPPED WITH GASOLINE ENGINES AND A 42/44/46 OR 47RE TRANSMISSION.
SYMPTOM/CONDITION:
Some vehicles may experience bucking during wide open throttle (WOT) acceleration. The bucking
occurs at approximately 5300 RPM. This condition may be caused by reaching the high RPM fuel
shut off rev limit before the transmission can shift into the next higher gear and is most likely to
occur with high electrical loads (high beams on, heated back lite, heated seats, radio, HVAC blower
on MAX etc.). During high current demands, the generator may emit electrical noise that can affect
the transmission governor pressure sensor output. If this occurs, the transmission may not shift
properly to the next higher gear under (WOT) acceleration conditions and therefore reach the fuel
shut off rev limiter. This may be seen most often between the 2-3 shift but can also be experienced
between the 1-2 shift.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual,
verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes
(DTC's) are present, record them on the repair order and repair as necessary before proceeding
further with this bulletin.
NOTE:
ONLY PERFORM THE FOLLOWING PROCEDURE SAFELY ON A HIGHWAY OR ROAD
OBEYING ALL POSTED SPEED LIMITS AND LAWS.
Attempt to duplicate the condition by switching on all accessory loads and driving the vehicle with
WOT accelerations through a shift sequence to see if the engine will reach the fuel shut off rev
limiter before the 2-3 or 1-2 shift is made.
If the bucking condition is experienced at approximately 5300 RPM before making the appropriate
upshifts, switch off all electrical loads and repeat the procedure. Repeat the procedure with the
electrical loads on and off a second time. If the bucking occurs with the electrical loads on and
does not occur with the loads off, perform the Repair Procedure.

TRANSMISSION SPEED SENSOR
Transmission Output Speed Sensor
The speed sensor is located in the overdrive gear case. The sensor is positioned over the park
gear and monitors transmission output shaft rotating speed. Speed sensor signals are triggered by
the park gear lugs as they rotate past the sensor pickup face. Input signals from the sensor are
sent to the transmission control module for processing. The rear wheel speed sensor also serves
as a backup for the transmission speed sensor. Signals from this sensor are shared with the
powertrain control module. See: Brakes and Traction Control/Antilock Brakes / Traction Control

TRANSMISSION THROTTLE VALVE CABLE ADJUSTMENT
Throttle Valve Cable Attachment-At Engine
The transmission throttle valve is operated by a cam on the valve body throttle lever. The throttle
lever is actuated by a cable connected to the engine throttle body lever. A retaining clip at the
engine-end of the cable is removed to provide for cable adjustment. The retaining clip is then
installed back onto the throttle valve cable to lock in the adjustment.
A correctly adjusted throttle valve cable, will cause the throttle lever on the transmission to move
simultaneously with the throttle body lever from the idle position. Proper adjustment allows
simultaneous movement without causing the transmission throttle lever to move ahead of, or lag
behind the throttle body lever.
THROTTLE VALVE CABLE ADJUSTMENT CHECK
1. Turn ignition key to OFF position. 2. Remove air cleaner. 3. Verify that throttle body lever is at
curb idle position. Then verify that transmission throttle lever is also at idle (full forward) position. 4.
Slide cable off attachment stud on throttle body lever. 5. Compare position of cable end to
attachment stud on throttle body lever:
a. Cable end and attachment stud should be aligned (or centered on one another) to within 1 mm
(0.039 inch) in either direction. b. If cable end and attachment stud are misaligned (off center),
cable will have to be adjusted as described in following procedure.
6. Reconnect cable end to attachment stud. Then with aid of a helper, observe movement of
transmission throttle lever and lever on throttle body.
a. If both levers move simultaneously from idle to half-throttle and back to idle position, adjustment
is correct. b. If transmission throttle lever moves ahead of, or lags behind throttle body lever, cable
adjustment will be necessary. Or, if throttle body lever
prevents transmission lever from returning to closed position, cable adjustment will be necessary.
THROTTLE VALVE CABLE ADJUSTMENT PROCEDURE
1. Turn ignition switch to OFF position and shift into Park. 2. Remove air cleaner. 3. Disconnect
cable end from attachment stud on throttle body Carefully slide cable off stud. Do not pull or pry
cable off. 4. Verify that transmission throttle lever is in idle (full forward) position. Then be sure
lever on throttle body is at curb idle position. 5. Insert a small screwdriver under edge of retaining
clip and remove retaining clip. 6. Center cable end on attachment stud to within 1 mm (0.039 inch).
7. Install retaining clip onto cable housing. 8. Check cable adjustment. Be sure transmission throttle
lever and lever on throttle body move simultaneously and as described in cable adjustment
checking procedure.

TRANSMISSION THROTTLE VALVE CABLE ADJUSTMENT
Throttle Valve Cable Attachment-At Engine
The transmission throttle valve is operated by a cam on the valve body throttle lever. The throttle
lever is actuated by a cable connected to the engine throttle body lever. A retaining clip at the
engine-end of the cable is removed to provide for cable adjustment. The retaining clip is then
installed back onto the throttle valve cable to lock in the adjustment.
A correctly adjusted throttle valve cable, will cause the throttle lever on the transmission to move
simultaneously with the throttle body lever from the idle position. Proper adjustment allows
simultaneous movement without causing the transmission throttle lever to move ahead of, or lag
behind the throttle body lever.
THROTTLE VALVE CABLE ADJUSTMENT CHECK
1. Turn ignition key to OFF position. 2. Remove air cleaner. 3. Verify that throttle body lever is at
curb idle position. Then verify that transmission throttle lever is also at idle (full forward) position. 4.
Slide cable off attachment stud on throttle body lever. 5. Compare position of cable end to
attachment stud on throttle body lever:
a. Cable end and attachment stud should be aligned (or centered on one another) to within 1 mm
(0.039 inch) in either direction. b. If cable end and attachment stud are misaligned-aligned (off
center), cable will have to be adjusted as described in following procedure.
6. Reconnect cable end to attachment stud. Then with aid of a helper, observe movement of
transmission throttle lever and lever on throttle body
a. If both levers move simultaneously from idle to half-throttle and back to idle position,, adjustment
is correct. b. If transmission throttle lever moves ahead of, or lags behind throttle body lever, cable
adjustment will be necessary. Or, if throttle body lever
prevents transmission lever from returning to closed position, cable adjustment will be necessary.
THROTTLE VALVE CABLE ADJUSTMENT PROCEDURE
1. Turn ignition switch to OFF position and shift into Park. 2. Remove air cleaner. 3. Disconnect
cable end from attachment stud on throttle body. Carefully slide cable off stud. Do not pull or pry
cable off. 4. Verify that transmission throttle lever is in idle (full forward) position. Then be sure
lever on throttle body is at curb idle position. 5. Insert a small screwdriver under edge of retaining
clip and remove retaining clip. 6. Center cable end on attachment stud to within 1 mm (0.039 inch).
7. Install retaining clip onto cable housing 8. Check cable adjustment. Be sure transmission throttle
lever and lever on throttle body move simultaneously and as described in cable adjustment
checking procedure.

Repair Procedure
This bulletin involves installing a cold weather by-pass kit to the transmission cooler circuit,
selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software
(calibration changes for 1996 models only), and using the DRB III to selectively turn off the
overdrive inhibitor feature for all applications.
NOTE:
IT IS ESSENTIAL THAT THE TRANSMISSION COOLER BYPASS KIT BE INSTALLED PRIOR
TO DISABLING THE INHIBITOR FEATURE. TRANSMISSION DAMAGE MAY OCCUR IF THE
BYPASS KIT IS NOT INSTALLED.
NOTE:
EVEN WITH BYPASS KIT INSTALLATION AND THE INHIBITOR FEATURE TURNED OFF, 4TH
GEAR WILL BE INHIBITED UNTIL THE OIL SUMP TEMPERATURE REACHES 0 C (30 F). THIS
MAY TAKE SEVERAL MINUTES.
Bypass Kit Installation
1. Record all radio pre-sets and disconnect the negative battery cable.
2. Raise the vehicle for access to the transmission housing. The bypass assembly will be
connected to the existing transmission lines and mounted to the transmission housing by means of
a bypass adapter.
3. During this installation procedure, some transmission fluid will be lost when the transmission
cooler lines are cut (allowing bypass assembly installation). Take proper precautions and check
transmission fluid fill level upon completing the installation.
4. It the cold weather bypass kit has provision for an in-line temperature sensor, the threaded
"therm-o-well" (in the pressure "P" line of the kit) must be plugged with either the temperature
sensor from the existing transmission line or the standard pipe plug provided. Consequently, if the
vehicle being serviced is equipped with a temperature sensor (i.e., heavy duty BR truck), remove
the temperature sensor from the existing line by un-threading and install it in the "pressure" line
provided with the kit. Use Mopar Thread Sealant, p/n 04318044, to ensure a leak free seal.
5. Disconnect the pressure and return lines from the transmission housing fittings.
6. Remove and discard the fittings from the transmission housing.
7. Apply Mopar Thread Sealant, p/n 04318044, to the threaded bypass adapter (# 2 Figure 1).
8. Install the threaded bypass adapter securely into the front pressure port of the transmission
housing and torque to 17.6 Nm (13 ft. lbs.).
9. Make sure the snap ring and O-ring are properly installed in their respective grooves on the nose
of the bypass assembly block. Lubricate the O-ring with ATF.
10. Position the bypass assembly block such that the return port fitting "R" is pointed directly up
and the two other fittings are pointed forward.
11. Firmly press the male nose of the bypass assembly into the female body of the threaded
bypass adapter until it snaps into place. After snapping into place, the bypass assembly is
permanently attached to the adapter.
NOTE:
THE BYPASS ASSEMBLY CAN ROTATE INSIDE THE ADAPTER, AND REMOVAL OF THE
BLOCK FROM THE TRANSMISSION HOUSING (IF REQUIRED) CAN BE ACCOMPLISHED BY
UN-THREADING THE ADAPTER.
CAUTION:
IF FLUSHING THE BYPASS ASSEMBLY IS REQUIRED, IT MUST BE REMOVED FROM THE
TRANSMISSION HOUSING AND FORWARD FLUSHED ONLY. FAILING TO REMOVE THE
VALVE AND REVERSE FLUSHING WILL RESULT IN TRANSMISSION FAILURE BY PLUGGING
THE BYPASS VALVES INTERNAL ORIFICE AND DRAIN BACK VALVE.
12. Apply Mopar Thread Sealant, p/n 04318044, to the threaded end (transmission housing end) of
the compression fitting.
13. Install the threaded compression fitting securely into the rear return port of the transmission
housing and torque to 17.6 Nm (13 ft. lbs.).

14. Using a small tubing cutter, cut the existing pressure line at approximately 120 mm (5 in.) from
the transmission housing end. Repeat the procedure for the existing return line.
CAUTION:
AFTER CUTTING THE PRESSURE LINE, MARK IT WITH A PIECE OF TAPE FOR
IDENTIFICATION.
15. Identify the proper return line ("R" line) by using the marked labels attached to the tubes.
16. Connect the "R" line to the bypass assembly block and the rearward return port of the
transmission housing. Tighten the compression fitting finger tight, and then wrench tighten it an
additional 1/2 turn. Tighten the inverted flare nut to 6.78 Nm (60 in. lbs.).
17. Select the appropriate "RR" and "P" tubes for the application. Mixing or matching may be
required to provide the best routing for your

REMOVAL FOR BYPASS TUBE CLEARANCE. ONCE THE TUBES ARE INSTALLED LOOSELY,
INSTALL THE BRACKET AND THROTTLE VALVE CABLE. MAKE ANY ADJUSTMENTS FOR
CLEARANCE AND TIGHTEN THE BYPASS TUBES AND BRACKET ASSEMBLY.
20. Make sure that the existing return line is properly re-attached to the hanger bracket and lay the
new return line, "RR", beside it.
21. Install the hose bracket (# 12 in Figure 1) required for the overhead line application. The
bracket will replace the existing bracket at the starter mount location. It may require slight
modification to provide the best clearance from the exhaust system.
22. Attach clamp (# 11 in Figure 1) and the rubber hose to the "RR" tube to determine the
approximate rubber hose routing. For connection to the existing return line, the line may be cut
again to provide optimum line routing.

"therm-o-well" (in the pressure "P" line of the kit) must be plugged with either the temperature
sensor from the existing transmission line or the standard pipe plug provided. Consequently, if the
vehicle being serviced is equipped with a temperature sensor (i.e., heavy duty BR truck), remove
the temperature sensor from the existing line by un-threading and install it in the "pressure" line
provided with the kit. Use Mopar Thread Sealant, p/n 04318044, to ensure a leak free seal.
5. Disconnect the pressure and return lines from the transmission housing fittings.
6. Remove and discard the fittings from the transmission housing.

housing and torque to 17.6 Nm (13 ft. lbs.).
9. Make sure the snap ring and O-ring are properly installed in their respective grooves on the nose
of the bypass assembly block. Lubricate the O-ring with ATF.
10. Position the bypass assembly block such that the return port fitting "R" is pointed directly up
and the two other fittings are pointed forward.
11. Firmly press the male nose of the bypass assembly into the female body of the threaded
bypass adapter until it snaps into place. After snapping into place, the bypass assembly is
permanently attached to the adapter.
NOTE:
THE BYPASS ASSEMBLY CAN ROTATE INSIDE THE ADAPTER, AND REMOVAL OF THE
BLOCK FROM THE TRANSMISSION HOUSING (IF REQUIRED) CAN BE ACCOMPLISHED BY
UN-THREADING THE ADAPTER.
CAUTION:
IF FLUSHING THE BYPASS ASSEMBLY IS REQUIRED, IT MUST BE REMOVED FROM THE
TRANSMISSION HOUSING AND FORWARD FLUSHED ONLY. FAILING TO REMOVE THE
VALVE AND REVERSE FLUSHING WILL RESULT IN TRANSMISSION FAILURE BY PLUGGING
THE BYPASS VALVES INTERNAL ORIFICE AND DRAIN BACK VALVE.

TRANSMISSION SPEED SENSOR
Transmission Output Speed Sensor
The speed sensor is located in the overdrive gear case. The sensor is positioned over the park
gear and monitors transmission output shaft rotating speed. Speed sensor signals are triggered by
the park gear lugs as they rotate past the sensor pickup face. Input signals from the sensor are
sent to the transmission control module for processing. The rear wheel speed sensor also serves
as a backup for the transmission speed sensor. Signals from this sensor are shared with the
powertrain control module. See: Brakes and Traction Control/Antilock Brakes / Traction Control

CONTROL PRESSURE ADJUSTMENTS
There are two control pressure adjustments on the valve body; Line Pressure
- Throttle Pressure
Line and throttle pressures are interdependent because each affects shift quality and timing. As a
result, both adjustments must be performed properly and in the correct sequence. Adjust line
pressure first and throttle pressure last.
LINE PRESSURE ADJUSTMENT
Line Pressure Adjustment
Measure distance from the valve body to the inner edge of the adjusting screw with an accurate
steel scale.
Distance should be 33.4 mm (1-5/16 inch).
If adjustment is required, turn the adjusting screw in, or out, to obtain required distance setting.
NOTE: The 33.4 mm (1-5/16 inch) setting is an approximate setting. Manufacturing tolerances may
make it necessary to vary from this dimension to obtain desired pressure.
One complete turn of the adjusting screw changes line pressure approximately 1-2/3 psi (9 kPa).
Turning the adjusting screw counterclockwise increases pressure while turning the screw clockwise
decreases pressure.
THROTTLE PRESSURE ADJUSTMENT
Throttle Pressure Adjustment
Insert Gauge Tool C-3763 between the throttle lever cam and the kickdown valve stem.
Push the gauge tool inward to compress the kickdown valve against the spring and bottom the
throttle valve.

Valve Body: Service and Repair Cleaning and Inspection
Clean the valve housings, valves, plugs, springs, and separator plates with a standard parts
cleaning solution only. Do not use gasoline, kerosene, or any type of caustic solution.
Do not immerse any of the electrical components in cleaning solution. Clean the governor solenoid
and sensor and the dual solenoid and harness assembly by wiping them off with dry shop towels
only.
Dry all except the electrical parts with compressed air. Make sure all passages are clean and free
from obstructions. Do not use rags or shop towels to dry or wipe off valve body components. Lint
from these materials can stick to valve body parts, interfere with valve operation, and clog filters
and fluid passages.
Wipe the governor pressure sensor and solenoid valve with dry, lint free shop towels only. The
O-rings on the sensor and solenoid valve are the only serviceable components. Be sure the vent
ports in the solenoid valve are open and not blocked by dirt or debris. Replace the valve and/or
sensor only when DRB scan tool diagnosis indicates this is necessary. Or, if either part has
sustained physical damage (dented, deformed, broken, etc.).
CAUTION: Do not turn the small screw at the end of the solenoid valve for any reason. Turning the
screw in either direction will ruin solenoid calibration and result in solenoid failure. In addition, the
filter on the solenoid valve is NOT serviceable. Do not try to remove the filter as this will damage
the valve housing.

Upper Housing Valves, Plugs, Springs And Brackets
Inspect the throttle and manual valve levers and shafts. Do not attempt to straighten a bent shaft or
correct a loose lever. Replace these components if worn, bent, loose or damaged in any way.
Inspect all of the valve body mating surfaces for scratches, nicks, burrs, or distortion. Use a
straightedge to check surface flatness. Minor scratches may be removed with crocus cloth using
only very light pressure.
Minor distortion of a valve body mating surface may be corrected by smoothing the surface with a
sheet of crocus cloth. Position the crocus cloth on a surface plate, sheet of plate glass or equally
flat surface. If distortion is severe or any surfaces are heavily scored, the valve body will have to be
replaced.

Component Information > Service and Repair > Removal and Installation > Page 3683
CAUTION: Many of the valves and plugs, such as the throttle valve, shuttle valve plug, 1-2 shift
valve and 1-2 governor plug, are made of coated aluminum. Aluminum components are identified
by the dark color of the special coating applied to the surface (or by testing with a magnet). Do not
sand aluminum valves or plugs under any circumstances. This practice could damage the special
coating causing the valves/plugs to stick and bind.
Inspect the valves and plugs for scratches, burrs, nicks, or scores. Minor surface scratches on steel
valves and plugs can be removed with crocus cloth but do not round off the edges of the valve or
plug lands. Maintaining sharpness of these edges is vitally important. The edges prevent foreign
matter from lodging between the valves and plugs and the bore.
Inspect all the valve and plug bores in the valve body. Use a penlight to view the bore interiors.
Replace the valve body if any bores are distorted or scored. Inspect all of the valve body springs.
The springs must be free of distortion, warpage or broken coils.
Check the two separator plates for distortion or damage of any kind. Inspect the upper housing,
lower housing, 3-4 accumulator housing, and transfer plate carefully. Be sure all fluid passages are
clean and clear. Check condition of the upper housing and transfer plate check balls as well. The
check balls and ball seats must not be worn or damaged.
Trial fit each valve and plug in its bore to check freedom of operation. When clean and dry, the
valves and plugs should drop freely into the bores.
Valve body bores do not change dimensionally with use. If the valve body functioned correctly
when new, it will continue to operate properly after cleaning and inspection. It should not be
necessary to replace a valve body assembly unless it is damaged in handling.
The only serviceable valve body components are listed below. The remaining valve body
components are serviced only as part of a complete valve body assembly. Serviceable parts are:
- dual solenoid and harness assembly
- solenoid gasket
- solenoid case connector O-rings and shoulder bolt
- switch valve and spring
- pressure adjusting screw and bracket assembly
- throttle lever
- manual lever and shaft seal
- throttle lever shaft seal, washer, and E-clip

Carrier Bearings: Adjustments Rear Axle - 8 1/4 and 9 1/4
DIFFERENTIAL BEARING PRELOAD AND GEAR BACKLASH
The following must be considered when adjusting bearing pre-load and gear backlash: The maximum ring gear backlash variation is 0.003 inch (0.076 mm).
- Mark the gears so the same teeth are meshed during all backlash measurements.
- Maintain the torque while adjusting the bearing pre-load and ring gear backlash.
- Excessive adjuster torque will introduce a high bearing load and cause premature bearing failure.
Insufficient adjuster torque can result in excessive differential case free-play and ring gear noise.
- Insufficient adjuster torque will not support the ring gear correctly and can cause excessive
differential case free-play and ring gear noise.
NOTE: The differential bearing cups will not always immediately follow the threaded adjusters as
they are moved during adjustment. To ensure accurate bearing cup responses to the adjustments:
Maintain the gear teeth engaged (meshed) as marked.
- The bearings must be seated by rapidly rotating the pinion gear a half turn back and forth.
- Do this five to ten times each time the threaded adjusters are adjusted.
Threaded Adjuster Tool
1. Use Wrench C-4164 to adjust each threaded adjuster inward until the differential bearing
freeplay is eliminated. Allow some ring gear backlash
(approximately 0.01 inch/0.25 mm) between the ring and pinion gear. Seat the bearing cups with
the procedure described above.
Ring Gear Backlash Measurement
2. Install dial indicator and position the plunger against the drive side of a ring gear tooth. Measure
the backlash at 4 positions (90° apart) around the
ring gear. Locate and mark the area of minimum backlash.
3. Rotate the ring gear to the position of the least backlash. Mark the gear so that all future
backlash measurements will be taken with the same gear
teeth meshed.
4. Loosen the right-side, tighten the left-side threaded adjuster. Obtain backlash of 0.003 to 0.004
inch (0.076 to 0.102 mm) with each adjuster
tightened to 14 Nm (10 ft. lbs.). Seat the bearing cups with the procedure described above.
5. Tighten the differential bearing cap bolts; 8 1/4 axles: 95 Nm (70 ft. lbs.)
- 9 1/4 axles: 136 Nm (100 ft. lbs.)
6. Tighten the right-side threaded adjuster to 102 Nm (75 ft. lbs.). Seat the bearing cups with the
procedure described above. Continue to tighten the

right-side adjuster and seat bearing cups until the torque remains constant at 102 Nm (75 ft. lbs.)
7. Measure the ring gear backlash. The range of backlash is 0.006 to 0.008 inch (0.15 to 0.203
mm). 8. Continue increasing the torque at the rightside threaded adjuster until the specified
backlash is obtained.
NOTE: The left-side threaded adjuster torque should have approximately 102 Nm (75 ft. lbs.). If the
torque is considerably less, the complete adjustment procedure must be repeated.
9. Tighten the left-side threaded adjuster until 102 Nm (75 ft. lbs.) torque is indicated. Seat the
bearing rollers with the procedure described above.
Do this until the torque remains constant.
10. Install the threaded adjuster locks and tighten the lock screws to 10 Nm (90 inch lbs.).
After the proper backlash is achieved, perform the Gear Contact Analysis procedure.

INTRODUCTION
Axle Adjustment Shim Locations-248 RBI
Differential side bearing pre-load and gear backlash is achieved by selective shims positioned
behind the differential side bearing cones. The proper shim thickness can be determined using
slip-fit dummy bearings D-343 in place of the differential side bearings and a dial indicator C-3339.
Before proceeding with the differential bearing pre-load and gear backlash measurements,
measure the pinion gear depth and prepare the pinion gear for installation. Establishing proper
pinion gear depth is essential to establishing gear backlash and tooth contact patterns. After the
overall shim thickness to take up differential side play is measured, the pinion gear is installed, and
the gear backlash shim thickness is measured. The overall shim thickness is the total of the dial
indicator reading and the pre-load specification added together. The gear backlash measurement
determines the thickness of the shim used on the ring gear side of the differential case. Subtract
the gear backlash shim thickness from the total overall shim thickness and select that amount for
the pinion gear side of the differential. Differential shim measurements are performed with axle
spreader W-129-B removed.
SHIM SELECTION
NOTE: It is difficult to salvage the differential side bearings during the removal procedure. Install
replacement bearings if necessary.
1. Remove differential side bearings from differential case. 2. Remove factory installed shims from
differential case. 3. Install ring gear on differential case and tighten bolts to specification, if

Backlash Shim Adjustment
38. Push and hold ring gear downward while not allowing the pinion gear to rotate. Dial indicator
reading should be between 0.12 mm (0.005 inch)
and 0.20 mm (0.008 inch). If backlash is not within specifications transfer the necessary amount of
shim thickness from one side of the axle housing to the other.
39. Verify differential case and ring gear runout by measuring ring to pinion gear backlash at
several locations around the ring gear. Readings should
not vary more than 0.05 mm. (0.002 inch). If readings vary more than specified, the ring gear or the
differential case is defective.
After the proper backlash is achieved, perform Gear Contact Pattern Analysis procedure.

SIDE GEAR CLEARANCE
When measuring side gear clearance, check each gear independently. If it necessary to replace a
side gear, replace both gears as a matched set. 1. Install the axle shafts and C-clip locks and
pinion mate shaft.
Side Gear Clearance Measurement
2. Measure each side gear clearance. Insert a matched pair of feeler gauge blades between the
gear and differential housing on opposite sides of the
hub.
3. If side gear clearances is no more than 0.005 inch. Determine if the shaft is contacting the pinion
gear mate shaft. Do not remove the feeler gauges,
inspect the axle shaft with the feeler gauge inserted behind the side gear. If the end of the axle
shaft is not contacting the pinion gear mate shaft, the side gear clearance is acceptable.
Side Gear Calculations
4. If clearance is more than 0.005 inch (axle shaft not contacting mate shaft), record the side gear
clearance. Remove the thrust washer and measure
its thickness with a micrometer. Add the washer thickness to the recorded side gear clearance. The
sum of gear clearance and washer thickness will determine required thickness of replacement
thrust washer. In some cases, the end of the axle shaft will move and contact the mate shaft when
the feeler gauge is inserted. The C-clip lock is preventing the side gear from sliding on the axle
shaft.
5. If there is no side gear clearance, remove the C-clip lock from the axle shaft. Use a micrometer
to measure the thrust washer thickness. Record the
thickness and re-install the thrust washer. Assemble the differential case without the C-clip lock
installed and re-measure the side gear clearance.
6. Compare both clearance measurements. If the difference is less than 0.012 inch (0.305 mm),
add clearance recorded when the C-clip lock was
installed to thrust washer thickness measured. The sum will determine the required thickness of the
replacement thrust washer.
7. If clearance is 0.012 inch (0.305 mm) or greater, both side gears must be replaced (matched set)
and the clearance measurements repeated. 8. If clearance (above) continues to be 0.012 inch
(0.305 mm) or greater, the case must be replaced.

NOTE:
THIS BULLETIN APPLIES TO ALL VEHICLES EQUIPPED WITH AN 8.25, 9.25, OR C205F
CORPORATE AXLE.
DISCUSSION: The axle lubricant used in all corporate axles was changed in formulation starting at
the beginning of the 1998 model year. The corporate axles involved include: the 8.25 and 9.25 rear
axles, and the C205F front axle. The new lubricant in use is SAE 75W-90 p/n 05010320AA. The
lubricant change was made as a fuel economy improvement.
The new axle lubricant is more chemically aggressive/reactive when in contact with the previous
used Room Temperature Vulcanizable (RTV) sealant. Because of this condition, the RTV used in
assembly of the pan/cover to the axle housing was revised and improved.
When re-sealing axle covers, using the proper sealing material to minimize any potential sealant
breakdown is important. The only recommended sealing material for all corporate axle covers is
MOPAR RTV Sealant, p/n 05013477M. This RTV is red/orange in color.
NOTE:
IF SAE 75W-90 LUBRICANT IS USED TO REFILL ANY CORPORATE AXLE, THEN THE
RED/ORANGE MOPAR RTV SEALANT, P/N 05013477AA, SHOULD BE USED TO SEAL THE
COVER TO THE AXLE HOUSING.
To optimize sealant performance and enhance adhesion, flanges should be clean and free of
residual lubricant. The mating flanges should first be cleaned of any excess old RTV using a plastic
putty knife. Final cleaning/degreasing shall be done by spraying MOPAR Brake Parts Cleaner, p/n
04549623, on the carrier and cover flanges, followed by a wipe with a clean dry cloth. Care should
be taken to avoid spraying the parts cleaner inside the carrier. Once the RTV has been applied, the
axle cover is to be installed to the housing within 3 to 5 minutes to prevent skinning over of the
RTV.
NOTE:
IF THE AXLE COVER IS NOT INSTALLED WITHIN THE 3 TO 5 MINUTE TIME FRAME, THE
CARRIER COVER FACE MUST BE RECLEANED AND NEW RTV APPLIED, OR ADHESION
QUALITY WILL BE COMPROMISED.
Immediately install the cover attaching bolts and tighten them to the specified torque to prevent a
shimming effect by the RTV.

DISCUSSION:
With the introduction of the 1998 model year, the axle lubricant in the 8-1/4 and 9-1/4 axles was
changed in formulation to improve fuel economy. When adding lubricant or if service is performed
that requires new lubricant use 75W90 p/n 5010320AA.
This lubricant is more aggressive toward RTV sealants than previously used axle lubricants. When
resealing the axle cover, using the proper sealing material to minimize any potential fluid foaming
and/or seal breakdown is important. Currently the only recommended sealing material for mall axle
covers or transmission pans is MOPAR RTV Sealant (grey in color) p/n 82300234.

GENERAL INFORMATION
Pinion Gear ID Numbers
Ring and pinion gears are supplied as matched sets only. The identifying numbers for the ring and
pinion gear are marked on the face of each gear. A plus (+) number, minus (-) number or zero (0)
is marked on the face of the pinion gear. This number is the amount (in thousandths of an inch) the
depth varies from the standard depth setting of a pinion marked with a (0). The standard depth
provides the best teeth contact pattern. Refer to Backlash and Contact Pattern Analysis Paragraph
for additional information.
Shim Locations
Compensation for pinion depth variance is achieved with select shims. The shims are placed under
the rear pinion bearing cone.
If a new gear set is being installed, note the depth variance marked on both the original and
replacement pinion gear. Add or subtract the thickness of the original depth shims to compensate
for the difference in the depth variances. Refer to the Depth Variance charts.

Note where Old and New Pinion Marking columns intersect. Intersecting figure represents plus or
minus amount needed. Note the marked number on the face of the drive pinion gear (-1, -2, 0, +1,
+2, etc.). The numbers represent thousands of an inch deviation from the standard. If the number
is negative, add that value to the required thickness of the depth shim(s). If the number is positive,
subtract that value from the thickness of the depth shim(s). If the number is 0 no change is
necessary. Refer to the Pinion Gear Depth Variance Chart.

NUMBER: 19-07-00
GROUP: Steering
DATE: September 22, 2000
SUBJECT: Steering Wander Diagnosis
OVERVIEW: This bulletin provides a diagnostic procedure for steering wander.
MODELS: 1998-2001 (AB) Ram Van/Wagon
SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight
steering corrections are necessary to be able to keep the vehicle moving in a straight line.
Steering wander can be created by a number of different conditions including but not limited to the
following:
^ Non-factory installed options.
^ Tires or wheels of different size.
^ Aftermarket wheels.
^ Tires that have a belt that has shifted.
^ Incorrect tire pressure.
^ A vehicle that is carrying extra added weight (e.g. tool boxes).
^ Steering and/or suspension components that are worn or damaged.
^ Wheel bearings that are loose, worn, or damaged.
^ A vehicle that is not within alignment specifications.
NOTE:
UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS,
CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER.
The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering
system components are functioning as designed and are not the root cause of steering wander.
DIAGNOSIS:
1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may
cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to
exceed the front or rear Gross Axle Weight Rating (GAWR).
2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged
and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to
wander and should be replaced before continuing with the diagnosis.
3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove
box).
NOTE:
TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN
PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB
OR LIGHT LOAD CONDITIONS.
4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road
crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70
mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the
vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a
steering wander condition.
NOTE:
VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD
TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION
MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED
ROADS, ETC.).
5. Raise the vehicle on an appropriate lift.

Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 3893
6. Secure a dial indicator to the lower control arm. Position the dial indicator so that the tip of the
indicator contacts the inside face of the rotor (Figure 1).
7. Place your hands at the top and bottom of the tire/wheel assembly and push the tire/wheel
assembly inboard (Figure 2). Zero the dial indicator. With your hands at the top and bottom of the
tire/wheel assembly, pull the tire/wheel assembly outboard (Figure 3). Record the dial indicator
reading. Perform this procedure on both front wheel bearings and proceed to the next step if the
wheel bearing endplay exceeds 0.025 - 0.076 mm (0.001 - 0.003 in.). Proceed to Step 9 if
wheel-bearing endplay on both front wheel bearings are within specifications.
NOTE:
WHEEL BEARING INSPECTION AND ADJUSTMENT IS ONLY REQUIRED ON WHEEL
BEARINGS EXCEEDING 0.025 - 0.076 MM (0.001 - 0.003 IN.) ENDPLAY.
8. Remove the wheel bearing protective end cap, cotter pin, nut lock, nut, and washer from the
spindle. Inspect the wheel bearings. If it is determined that wheel bearing replacement is
necessary, refer to the appropriate Ram Van/Wagon Service Manual, Group 02, Wheel Bearings,
for removal and installation information. Reinstall the wheel bearings, washer, and adjustment nut if
the wheel bearings pass the inspection.
9. Using a torque wrench, tighten the wheel bearing adjustment nut to 54 N.m (40 ft. lbs.) while
rotating the tire/wheel assembly. Stop the wheel from rotating and loosen the nut. Using the
procedure identified in Steps 6 and 7 to measure endplay, adjust the front wheel bearing endplay
until 0.025 - 0.076 mm (0.001 - 0.003 in.) endplay has been achieved. Install the nut lock and a
new cotter pin.
10. Perform the Pre-Alignment inspection as identified in Group 02, Service Procedures, of the
appropriate Ram Van/Wagon Service Manual. Any worn steering and/or suspension component
must be replaced prior to performing an alignment.

Overdrive Indicator Lamp: Description and Operation
SYSTEM OPERATION
The overdrive-off indicator lamp gives the driver an indication that the automatic transmission
overdrive has been locked out. The lamp is controlled by the Powertrain Control Module (PCM) on
a hard wired circuit to instrument cluster.
The PCM receives an input from the momentary overdrive lockout switch, which is located on the
end of the automatic transmission gearshift selector lever. The PCM uses the overdrive lockout
switch input, along with numerous other sensor inputs and its internal programming to decide
whether the over-drive-off indicator lamp should be on or off. The PCM then turns the lamp on or
off by controlling the ground path for the lamp control circuit.

Overdrive Indicator Lamp: Testing and Inspection
The diagnosis found here addresses an inoperative overdrive-off indicator lamp condition. If the
overdrive-off indicator lamp comes on and stays on with the engine running, refer to the proper
Diagnostic Procedures for diagnosis of the Powertrain Control Module (PCM) and the transmission
control system circuits.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL

SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too
High
OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain
Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and
99Cal14).
MODELS:
**1996** - 1999 (AB) Ram Van
**1996** - 1999 (AN) Dakota
**1996** - 1999 (BR/BE) Ram Truck
1998 - 1999 (DN) Durango
**1997** - 1999 (TJ) Wrangler
**1996** 1999 (XJ) Cherokee
**1996** - 1998 (ZJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC
TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX).
SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble
Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle
operator may experience slower than normal vehicle accelerations because the transmission may
have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode
may last until the vehicle owner cycles the ignition key. The technician may not detect a problem
with the automatic transmission during a diagnostic test or test drive.
The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the
result of a new valve body machining process, which entered into production January 1, 1998. This
condition will occur most often with vehicles that were built between January 1, 1998 and
December 18, 1998.
Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the
transmission assembly is replaced with components built after January 1, 1998.
DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB
III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission
systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record
them on the repair order and repair as necessary before proceeding further with this bulletin. If no
DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF
THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION
LEVEL. USE THE FLASH PROCEDURE TO UPDATE REPLACED CONTROLLERS AS
NECESSARY.

Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle
operator may experience slower than normal vehicle accelerations because the transmission may
have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode
may last until the vehicle owner cycles the ignition key. The technician may not detect a problem
with the automatic transmission during a diagnostic test or test drive.
The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the
result of a new valve body machining process, which entered into production January 1, 1998. This
condition will occur most often with vehicles that were built between January 1, 1998 and
December 18, 1998.
Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the
transmission assembly is replaced with components built after January 1, 1998.
DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB
III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission
systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record
them on the repair order and repair as necessary before proceeding further with this bulletin. If no
DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

NOTE:
THIS INFORMATION APPLIES TO VEHICLES BUILT BEFORE JAN 16, 1998 MDH (0116XX)
EQUIPPED WITH GASOLINE ENGINES AND A 42/44/46 OR 47RE TRANSMISSION.
SYMPTOM/CONDITION:
Some vehicles may experience bucking during wide open throttle (WOT) acceleration. The bucking
occurs at approximately 5300 RPM. This condition may be caused by reaching the high RPM fuel
shut off rev limit before the transmission can shift into the next higher gear and is most likely to
occur with high electrical loads (high beams on, heated back lite, heated seats, radio, HVAC blower
on MAX etc.). During high current demands, the generator may emit electrical noise that can affect
the transmission governor pressure sensor output. If this occurs, the transmission may not shift
properly to the next higher gear under (WOT) acceleration conditions and therefore reach the fuel
shut off rev limiter. This may be seen most often between the 2-3 shift but can also be experienced
between the 1-2 shift.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual,
verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes
(DTC's) are present, record them on the repair order and repair as necessary before proceeding
further with this bulletin.
NOTE:
ONLY PERFORM THE FOLLOWING PROCEDURE SAFELY ON A HIGHWAY OR ROAD
OBEYING ALL POSTED SPEED LIMITS AND LAWS.
Attempt to duplicate the condition by switching on all accessory loads and driving the vehicle with
WOT accelerations through a shift sequence to see if the engine will reach the fuel shut off rev
limiter before the 2-3 or 1-2 shift is made.
If the bucking condition is experienced at approximately 5300 RPM before making the appropriate
upshifts, switch off all electrical loads and repeat the procedure. Repeat the procedure with the
electrical loads on and off a second time. If the bucking occurs with the electrical loads on and
does not occur with the loads off, perform the Repair Procedure.

TRANSMISSION SPEED SENSOR
Transmission Output Speed Sensor
The speed sensor is located in the overdrive gear case. The sensor is positioned over the park
gear and monitors transmission output shaft rotating speed. Speed sensor signals are triggered by
the park gear lugs as they rotate past the sensor pickup face. Input signals from the sensor are
sent to the transmission control module for processing. The rear wheel speed sensor also serves
as a backup for the transmission speed sensor. Signals from this sensor are shared with the
powertrain control module. See: Brakes and Traction Control/Antilock Brakes / Traction Control

NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC
TRANSMISSION.
SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission
when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning"
like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100
F.). The condition is caused by a resonance of the transmission regulator valve system.
Other items may cause regulator valve resonance, including air ingestion into the valve body or out
of specification parts. These two items may be the result a possible cracked pump housing, a torn
pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of
specification valve and/or valve body. You should remember these additional items / components
when you perform your diagnosis.
Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve
body or an entire automatic transmission was replaced with components manufactured after
August 1, 1995.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual,
verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble
Codes (DTC's) are present, record them on the repair order and repair as necessary before
proceeding further with this bulletin.
For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to
determine if it applies to this vehicle before attempting to complete the analysis or repairs
described in this bulletin.
In most instances, the sump temperature of vehicles exhibiting transmission regulator valve
resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to
remain parked in a cool place overnight. Then perform the following steps:
1. Set the vehicle parking brake.
2. Start the engine (make certain windows are closed, to eliminate outside noise).
3. With brakes applied, place the transmission selector lever in reverse.
4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to
normal operating temperature (180 - 210 degrees F).
5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

Description and Operation
Overdrive Indicator Lamp: Description and Operation
SYSTEM OPERATION
The overdrive-off indicator lamp gives the driver an indication that the automatic transmission
overdrive has been locked out. The lamp is controlled by the Powertrain Control Module (PCM) on
a hard wired circuit to instrument cluster.
The PCM receives an input from the momentary overdrive lockout switch, which is located on the
end of the automatic transmission gearshift selector lever. The PCM uses the overdrive lockout
switch input, along with numerous other sensor inputs and its internal programming to decide
whether the over-drive-off indicator lamp should be on or off. The PCM then turns the lamp on or
off by controlling the ground path for the lamp control circuit.

Overdrive Indicator Lamp: Testing and Inspection
The diagnosis found here addresses an inoperative overdrive-off indicator lamp condition. If the
overdrive-off indicator lamp comes on and stays on with the engine running, refer to the proper
Diagnostic Procedures for diagnosis of the Powertrain Control Module (PCM) and the transmission
control system circuits.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
1. Check the fuse in the junction block. If OK, go to Step 3. If not OK, repair the shorted circuit or
component as required and replace the faulty fuse. 2. Turn the ignition switch to the On position.
Check for battery voltage at the fuse in the junction block. If OK, go to Step 4. If not OK, repair the
open circuit to the ignition switch as required.
3. Disconnect and isolate the battery negative cable. Unplug the gray PCM wire harness connector.
Install a jumper wire between the overdrive lamp
driver circuit cavity of the gray PCM wire harness connector and a good ground. Connect the
battery negative cable. Turn the ignition switch to the On position. The overdrive-off indicator lamp
should light. Remove the jumper wire and the lamp should turn off. If OK, refer to the proper
Diagnostic Procedures for diagnosis of the Powertrain Control Module (PCM) and the transmission
control system circuits. If not OK, go to Step 5.
4. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable.
Remove the instrument cluster. Check for continuity
between the overdrive lamp driver circuit cavity of the gray PCM wire harness connector and a
good ground. There should be no continuity. If OK, go to Step 6. If not OK, repair the short circuit
as required.
5. Check for continuity between the overdrive lamp driver circuit cavities of the gray PCM wire
harness connector and the instrument cluster wire
harness connector (connector A). There should be continuity. If OK, replace the faulty bulb. If not
OK, repair the open circuit as required.

1999, WHICH SHOULD BE REMOVED FROM YOUR FILES. ALL REVISIONS ARE
HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS.
SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too
High
OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain
Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and
99Cal14).
MODELS:
**1996** - 1999 (AB) Ram Van
**1996** - 1999 (AN) Dakota
**1996** - 1999 (BR/BE) Ram Truck
1998 - 1999 (DN) Durango
**1997** - 1999 (TJ) Wrangler
**1996** 1999 (XJ) Cherokee
**1996** - 1998 (ZJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC
TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX).
SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble
Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle
operator may experience slower than normal vehicle accelerations because the transmission may
have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode
may last until the vehicle owner cycles the ignition key. The technician may not detect a problem
with the automatic transmission during a diagnostic test or test drive.
The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the
result of a new valve body machining process, which entered into production January 1, 1998. This
condition will occur most often with vehicles that were built between January 1, 1998 and
December 18, 1998.
Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the
transmission assembly is replaced with components built after January 1, 1998.
DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB
III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission
systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record
them on the repair order and repair as necessary before proceeding further with this bulletin. If no
DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF
THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION
LEVEL. USE THE FLASH PROCEDURE TO UPDATE REPLACED CONTROLLERS AS
NECESSARY.

NOTE:
THIS INFORMATION APPLIES TO VEHICLES BUILT BEFORE JAN 16, 1998 MDH (0116XX)
EQUIPPED WITH GASOLINE ENGINES AND A 42/44/46 OR 47RE TRANSMISSION.
SYMPTOM/CONDITION:
Some vehicles may experience bucking during wide open throttle (WOT) acceleration. The bucking
occurs at approximately 5300 RPM. This condition may be caused by reaching the high RPM fuel
shut off rev limit before the transmission can shift into the next higher gear and is most likely to
occur with high electrical loads (high beams on, heated back lite, heated seats, radio, HVAC blower
on MAX etc.). During high current demands, the generator may emit electrical noise that can affect
the transmission governor pressure sensor output. If this occurs, the transmission may not shift
properly to the next higher gear under (WOT) acceleration conditions and therefore reach the fuel
shut off rev limiter. This may be seen most often between the 2-3 shift but can also be experienced
between the 1-2 shift.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual,
verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes
(DTC's) are present, record them on the repair order and repair as necessary before proceeding
further with this bulletin.
NOTE:
ONLY PERFORM THE FOLLOWING PROCEDURE SAFELY ON A HIGHWAY OR ROAD
OBEYING ALL POSTED SPEED LIMITS AND LAWS.
Attempt to duplicate the condition by switching on all accessory loads and driving the vehicle with
WOT accelerations through a shift sequence to see if the engine will reach the fuel shut off rev
limiter before the 2-3 or 1-2 shift is made.
If the bucking condition is experienced at approximately 5300 RPM before making the appropriate
upshifts, switch off all electrical loads and repeat the procedure. Repeat the procedure with the
electrical loads on and off a second time. If the bucking occurs with the electrical loads on and
does not occur with the loads off, perform the Repair Procedure.
PARTS REQUIRED:

Transmission Speed Sensor: Description and Operation
TRANSMISSION SPEED SENSOR
Transmission Output Speed Sensor
The speed sensor is located in the overdrive gear case. The sensor is positioned over the park
gear and monitors transmission output shaft rotating speed. Speed sensor signals are triggered by
the park gear lugs as they rotate past the sensor pickup face. Input signals from the sensor are
sent to the transmission control module for processing. The rear wheel speed sensor also serves
as a backup for the transmission speed sensor. Signals from this sensor are shared with the
powertrain control module. See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Wheel Speed Sensor

4WD Switch: Description and Operation
Vehicles equipped with four wheel drive (4WD) have an indicator switch mounted on the front axle
assembly. This switch is closed to ground when the transfer case is shifted to four wheel drive
mode and the engine is running on some vehicles. While in four wheel drive, the front and rear
axles will operate together. With this input, the CAB is able to modify its operation to allow for 4WD
operation. Should a need for antilock operation occur while in four wheel drive, the CAB will extend
the amount of allowable dump cycles.

ABS Light: Description and Operation General Information
SYSTEM OPERATION
The Anti-Lock Brake System (ABS)lamp gives an indication when the ABS system is faulty or
inoperative. The lamp is controlled by the instrument cluster circuitry based upon messages
received from the Controller Anti-lock Brake (CAB) on the Chrysler Collision Detection (CCD) data
bus. The lamp is turned on by the CAB for about two seconds when the ignition switch is turned to
the On position as a bulb test.
After the bulb test, the CAB turns the lamp on or off based upon the results of the ABS self-tests.
The CAB continually monitors the ABS circuits and sensors to decide whether the system is in
good operating condition. The CAB then sends the proper messages to the instrument cluster on
the CCD data bus to turn the lamp on or off. If the CAB turns the lamp on after the bulb test, it
indicates that the CAB has detected a system malfunction and/or that the ABS system has become
inoperative. If only the amber ABS lamp is illuminated, and the red brake warning lamp remains off,
the base brake system will operate normally.
Each time the instrument cluster circuitry receives a lamp-on message from the CAB, it will light the
lamp for the duration of the ABS malfunction. The CAB will also flash this lamp during the
diagnostic mode, unless a hard fault is present. If a hard fault is present, the ABS lamp will
illuminate without flashing.

ABS Light: Description and Operation Four Wheel Antilock Brakes
The amber ABS warning lamp is located in the instrument cluster. The lamp illuminates at start-up
to perform a self check. The lamp goes out when the self check program determines the system is
operating normal. If an ABS component exhibits a fault the Controller Antilock Brake (CAB) will
illuminate the lamp and register a trouble code in the microprocessor. The lamp is controlled by the
CAB. The CAB controls the lamp sending a message to the instrument cluster.

COULD RESULT IN ACCIDENTAL AIR BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
If the ABS lamp fails to light when the ignition switch is turned to the On position, replace the ABS
lamp bulb with a known good unit. If the ABS lamp still fails to operate, diagnosis of the ABS
system and the Chrysler Collision Detection (CCD) data bus should be performed with a DRB scan
tool as described in the proper Diagnostic Procedures. For further diagnosis of the ABS lamp and
the instrument cluster circuitry, see Instrument Cluster in the Diagnosis and Testing.

Module Corrosion
DEFECT: On some van and wagon model vehicles equipped with 4-wheel antilock brake systems
(ABS), aftermarket batteries may leak electrolyte onto the ABS control module connector, which
can compromise the sealing integrity of the connector. This may allow development of a short
circuit in the connector, which could eventually lead to a fire.
REMEDY: Dealers will inspect the ABS control module connector for electrolyte damage and
replace the connector as necessary. The manufacturer has not yet provided an owner notification
for this campaign. Owners may contact DaimlerChrysler at 1-800-853-1403.

DEFECT: On some van and wagon model vehicles equipped with 4-wheel antilock brake systems
(ABS), aftermarket batteries may leak electrolyte onto the ABS control module connector, which
can compromise the sealing integrity of the connector. This may allow development of a short
circuit in the connector, which could eventually lead to a fire.
REMEDY: Dealers will inspect the ABS control module connector for electrolyte damage and
replace the connector as necessary. The manufacturer has not yet provided an owner notification
for this campaign. Owners may contact DaimlerChrysler at 1-800-853-1403.

CAB/HCU
The Controller Antilock Brake (CAB) is mounted on the top of the hydraulic control unit.
The CAB operates the ABS system and is separate from other vehicle electrical circuits. CAB
voltage source is through the ignition switch in the RUN position.
The CAB contains dual microprocessors. A logic block in each microprocessor receives identical
sensor signals. These signals are processed and compared simultaneously.
The CAB contains a self check program that illuminates the ABS warning light when a system fault
is detected. Faults are stored in a diagnostic program memory and are accessible with the DRB
scan tool.
ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50
times. Stored faults are not erased if the battery is disconnected.
NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be
programed into the new CAB.

GENERAL INFORMATION
RWAL Controller Antilock Brake (CAB)
The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and
controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics.
- Monitors the RWAL brake system for proper operation.
- Controls the RWAL valve solenoids.
NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be
programed into the new CAB.
SYSTEM SELF-TEST
When the ignition switch is turned-on the microprocessor RAM and ROM are tested. If an error
occurs during the test a Diagnostic Trouble Code (DTC) will be set into the RAM memory. However
it is possible the DTC will not be stored in memory if the error has occurred in the RAM module
were the DTC's are stored. Also it is possible a DTC may not be stored if the error has occurred in
the ROM which signals the RAM to store the DTC.
CAB INPUTS
The CAB continuously monitors the speed of the differential ring gear by monitoring signals
generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency when it
recognizes the ring gear decelerating too rapidly. The CAB monitors the following inputs to
determine when a wheel locking tendency may exists: -
Rear Wheel Speed Sensor
- Brake Lamp Switch
- Brake Warning Lamp Switch
- Reset Switch
- 4WD Switch (If equipped)
CAB OUTPUTS

Hydraulic Control Assembly - Antilock Brakes: Description and Operation General Information
The controller-antilock brake module is used to monitor wheel speeds and modulates (control)
hydraulic pressure in each brake channel. The modulated hydraulic pressure is used to prevent
wheel lock up during braking. The CAB also provides a vehicle speed signal (VSS) to the
powertrain control module.

Hydraulic Control Assembly - Antilock Brakes: Description and Operation Hydraulic Control Unit
(HCU)
Description
The HCU on the EBC 2 has only a separate rear valve body.
The HCU on the EBC 325 has two integral valve bodies for controlling the front and rear brakes.
Within the HCU are solenoids, valves, check valves, and a reset switch necessary to apply and
release brake pressure as required to avoid wheel lockup, keep the wheels rolling, and maintain
optimum deceleration.
The isolation valve is normally open, allowing unrestricted flow from the master cylinder to the
wheels. When the CAB determines antilock intervention is required, the valve closes to isolate the
master cylinder hydraulic circuit. Fluid is trapped in the circuit and then prevented from reaching the
wheels.
The dump valve is pulsed on and off by the CAB. This valve cycles only if the isolation valve is
closed. When dump is on, it allows fluid to the low pressure accumulator for temporary storage.
This causes the pressure to the wheel to decrease. When the valve is off, fluid is allowed to the
wheel.
The brake return check valve allows the HCU to drain faster after the ABS stop, when the brake is
released.
The Reset Switch is positioned in the HCU to monitor the master cylinder (input), rear brake
(output) and accumulator pressure. During normal braking, pressure is equal for input and output
and the switch remains open. During an Antilock stop the switch will close as the isolation valve is
cycled and pressure becomes unequal between input and output. At the end of an ABS stop the
isolation valve will open as master cylinder pressure and rear pressure equalize. The switch is
used to monitor correct operation of the HCU and to set a diagnostic trouble code if incorrect
pressure is detected.
When the brakes are applied, fluid is forced from the master cylinder outlet ports to the HCU inlet
ports. This pressure is transmitted through three normally open isolation valves inside the HCU,
then through the outlet ports of the HCU to the wheels. If the CAB senses that a wheel is about to
lock, based on wheel speed sensor data, it pulls the normally open isolation valve closed for that
circuit. This prevents any more fluid from entering that circuit. The CAB continues to look at the
sensor signal to determine if the wheel is still decelerating. If deceleration is still taking place, the
normally closed dump valve for that circuit is opened. This dumps any pressure that is trapped
between the normally open valve and the brake back into an accumulator. Once the affected circuit
comes back up to speed, the CAB returns the valves to their normal condition allowing the affected
brake to be reapplied. On the EBC 325 system, the pump and accumulators are used to provide
rapid response during the reapply sequence and to minimize pedal feedback.
With Four Wheel Antilock Brakes
GENERAL INFORMATION
CAB/HCU
The Hydraulic Control Unit (HCU) consists of a valve body, pump, accumulator and motor.
The pump, motor, and accumulator are combined into an assembly attached to the valve body. The
accumulator store the extra fluid which had to be dumped from the brakes. This is done to prevent
the wheels from locking up. The pump provides the fluid volume needed and is operated by a DC
type motor. The motor is controlled by the Controller Antilock Brake (CAB).
The valve body contains the solenoid valves. The valves modulate brake pressure during antilock
braking and are controlled by the CAB.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Hydraulic Control
Assembly - Antilock Brakes > Component Information > Description and Operation > General Information > Page 4204
The HCU provides three channel pressure control to the front and rear brakes. One channel
controls the rear wheel brakes in tandem. The two remaining channels control the front wheel
brakes individually.
During antilock braking, the solenoid valves are opened and closed as needed. The valves are not
static. They are cycled rapidly and continuously to modulate pressure and control wheel slip and
deceleration.
During normal braking, the HCU solenoid valves and pump are not activated. The master cylinder
and power booster operate the same as a vehicle without an ABS brake system.
During antilock braking, solenoid valve pressure modulation occurs in three stages, pressure
decrease, pressure hold, and pressure increase. The valves are all contained in the valve body
portion of the HCU.
Pressure Decrease The inlet valve is closed and the outlet valve is opened during the pressure
decrease cycle.
A pressure decrease cycle is initiated when speed sensor signals indicate high wheel slip at one or
more wheels. At this point, the CAB closes the inlet to prevent the driver from further increasing the
brake pressure and locking the brakes. The CAB then opens the outlet valve, which also opens the
return circuit to the accumulators. Fluid pressure is allowed to bleed off (decrease) as needed to
prevent wheel lock.
Once the period of high wheel slip has ended, the CAB closes the outlet valve and begins a
pressure increase or hold cycle as needed.
Pressure Hold Both solenoid valves are closed in the pressure hold cycle. Fluid apply pressure in
the control channel is maintained at a constant rate. The CAB maintains the hold cycle until sensor
inputs indicate a pressure change is necessary.
Pressure Increase The inlet valve is open and the outlet valve is closed during the pressure
increase cycle. The pressure increase cycle is used to counteract unequal wheel speeds. This
cycle controls re-application of fluid apply pressure due to changing road surfaces or wheel speed.
With Rear Wheel Antilock Brakes
If the Controller Antilock Brake (CAB) senses that rear wheel speed deceleration is excessive, it
will energize a isolation solenoid by providing battery voltage to the solenoid. This prevents a
further increase of driver induced brake pressure to the rear wheels. If this initial action is not
enough to prevent rear wheel lock-up, the CAB will momentarily energize a dump solenoid (the
CAB energizes the dump solenoid by providing battery voltage to the solenoid). This opens the
dump valve to vent a small amount of isolated rear brake pressure to an accumulator. The action of
fluid moving to the accumulator reduces the isolated brake pressure at the wheel cylinders. The
dump (pressure venting) cycle is limited to very short time periods (milliseconds). The CAB will
pulse the dump valve until rear wheel deceleration matches the vehicle deceleration rate or the
desired slip rate programmed into the CAB. The system will switch to normal braking once wheel
locking tendencies are no longer present.
A predetermined maximum number of consecutive dump cycles can be performed during any one
antilock stop. If excessive dump cycles occur, a DTC will be set and stored in the CAB memory. If
during an antilock stop, the driver releases the brake pedal, the reset switch contacts will open.
This signal to the CAB is an indication that pressure has equalized across the RWAL valve. The
CAB will then reset the dump cycle counter in anticipation of the next antilock stop. Additionally,
any fluid stored in the accumulator will force its way past the dump valve, back into the hydraulic
circuit and return to the master cylinder.
A fuse internal to the CAB, provides a fail-safe device which prevents unwanted control over the
isolation and dump solenoids. The fuse is in series with the isolation and dump solenoids output
circuits. If the internal fuse is open, the CAB cannot provide voltage to energize either solenoid and
antilock stops are prevented. If the fuse is open, the braking system will operate normally but
without antilock control over rear brake pressure.

Wheel Speed Sensor: Description and Operation Four Wheel Antilock Brakes
OPERATION
The ABS brake system uses 3 wheel speed sensors. A sensor is mounted to each front steering
knuckles. The third sensor is mounted on top of the rear axle differential housing. The sensor is a
magnet coil that is mounted over a tone wheel front/exciter ring rear with an air gap between them.
The sensors measure the wheel speed by monitoring the rotation of the tone wheels front/exciter
ring rear. As the teeth of the tone wheels front/exciter ring rear move through the magnetic field of
the sensor an AC voltage is generated. This signal frequency increases or decreases proportionally
to the speed of the wheel. The Controller Antilock Brake (CAB) monitors these signals for changes
in wheel deceleration. If the CAB detects a sudden wheel or wheels deceleration within a
predetermined amount the CAB will activate the ABS system.
CIRCUIT OPERATION
The all wheel Anti-Lock Brake System (ABS) uses three wheel speed sensors; a single sensor for
both rear wheels and individual sensors for the front wheels. The single sensor used for the rear
wheels mounts on the top of the rear axle differential housing. Each sensor converts wheel speed
into an electrical signal that is transmitted to the Controller Anti-Lock Brakes (CAB). A pair of
twisted wires connect to each sensor and provide signals to the CAB.
Circuits B6 and B7 provide signals to the CAB from the right front wheel speed sensor. Circuit B6,
which provides the LOW signal, connects to cavity 15 of the CAB. Circuit B7 connects to cavity 2 of
the CAB and provides the HIGH signal.
Circuits B8 and B9 provide signals to the CAB from the left front wheel speed sensor. Circuit B8,
which provides the LOW signal, connects to cavity 16 of the CAB. Circuit B9 connects to cavity 3
and provides the HIGH signal.
Circuit B114 connects to cavity 14 of the CAB and to circuit B2 of the rear wheel speed sensor
harness at the sensor connector. Circuit B113 connects to cavity 1 of the CAB and to circuit B1 at
the rear wheel speed sensor harness connector. Circuit B114 provides the rear wheel speed
sensor LOW input while circuit B113 provides the HIGH input.

Wheel Speed Sensor: Description and Operation Kelsey-Hayes Antilock Brake Systems
The EBC 325 ABS system uses one wheel speed sensor on each front wheel, and one speed
sensor mounted in the rear axle for the rear wheels.
The RWAL II uses only one speed sensor mounted in the rear axle for the rear wheels.
The sensor measures the wheel speed by monitoring a rotating tone wheel. The signal generated
by the sensor and tone wheel is transmitted to the CAB.
Each sensor has:
- a metal tone wheel with teeth on its outside diameter
- a magnetic/coil pick-up (speed sensor) that is mounted to a fixed component
- an air gap between the tone wheel and the speed sensor assembly
As the teeth of the tone wheel move through the magnetic field of the sensor, an AC voltage is
generated. This signal frequency increases or decreases proportionally to the speed of the wheel.
The CAB monitors this signal to check for a sudden change in single or multiple wheel
decelerations. If the deceleration of one or more wheels is not within a predetermined amount, the
antilock module takes control.
Diagnostically, the coil of wheel speed sensors have different amounts of resistance based upon
the sensor type. When measured across the connector two terminals, the resistance should be:
AN, DN, BE and BR:
4x4 front sensors 945-1155 ohms
AB, AN and DN:
4x2 front sensors 2500-2955 ohms
BE and BR:
4x2 front sensors 1000-1250 ohms
AB, AN, DN, BE and BR:
All rear sensors 1600-2300 ohms
NOTE: For all resistance ranges add 30% to the value for extreme heat, subtract 30% for extreme
cold.)
The rear wheel speed sensor used on all vehicles have the same resistance value, but there are
two different sensors. Therefore, it is important to replace the rear wheel speed sensor with the
proper part.
On a EBC 325 system each front wheel speed is monitored through the speed sensor mounted at
the wheel end of the hub. On a EBC 325 and RWAL II system the rear wheel speed is monitored
through the speed sensor mounted in the rear axle assembly.
The CAB will disable antilock control, illuminate the ABS warning light circuit via COD, and store
trouble codes if it detects a problem with any or all of the wheel speed sensors:
- incorrect circuit resistance when checked with no vehicle movement
- incorrect sensor output during vehicle movement
- erratic sensor output during vehicle movement

Antilock Brake System Bleeding Procedures
Brake Bleeding: Service and Repair Antilock Brake System Bleeding Procedures
W/ Four Wheel Antilock Brakes
ABS system bleeding requires conventional bleeding methods plus use of the DRB scan tool. The
procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and
bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to
remove any air remaining in the system.
1. Perform base brake bleeding. 2. Connect scan tool to the Data Link Connector. 3. Select
ANTILOCK BRAKES, followed by MISCELLANEOUS, then BLEED BRAKES. Follow the
instructions displayed. When scan tool
displays TEST COMPLETE, disconnect scan tool and proceed.
4. Perform base brake bleeding a second time. 5. Top off master cylinder fluid level and verify
proper brake operation before moving vehicle.
W/ Rear Wheel Antilock Brakes
GENERAL INFORMATION
RWAL brake bleeding can be performed manually, or with pressure bleeding equipment.
Use Mopar DOT 3 brake fluid, or an equivalent meeting SAE J1703-F and DOT 3 standards, to fill
and bleed the brake system.
Bleed only one brake component at a time. Recommended bleed sequence is: master cylinder
- combination valve
- rear antilock valve
- left rear wheel
- right rear wheel
- right front wheel
- left front wheel
MANUAL BLEEDING
Use a bleed hose at each caliper/cylinder bleed screw. Attach one end of the hose to the bleed
screw and insert the opposite end in glass container partially filled with brake fluid. A glass
container makes it easier to see air bubbles as they exit the bleed hose. Be sure the end of the
bleed hose remains immersed in fluid. This prevents air from being drawn back into the system.
Do not allow the master cylinder to run out of fluid when bleeding the brakes. An empty cylinder will
allow air to be drawn back into the system. Check fluid level frequently during bleeding operations.
Be sure to tighten each brake line fitting, or bleed screw once bleeding is completed. Loose fittings
and bleed screws allows air to enter the system.
PRESSURE BLEEDING
If pressure bleeding equipment will be used, the front brake metering valve will have to be held
open to bleed the front brakes. The valve stem is located in the forward end of the combination
valve. The stem must either be pressed inward, or held outward slightly. a spring clip tool or helper
is needed to hold the valve stem in position.
Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the
tank manufacturers pressure recommendations. Generally, a tank pressure of 15 - 20 psi is
sufficient for bleeding.
Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to
leakage, or drawing air back into the system.

Brake Bleeding: Service and Repair Base Brake System Bleeding
GENERAL INFORMATION
Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards
only. Use fresh, clean fluid from a sealed container at all times.
Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into
small bubbles that are distributed throughout the hydraulic system. This will make additional
bleeding operations necessary.
Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will
allow additional air to be drawn into the system. Check the cylinder fluid level frequently and add
fluid as needed.
Bleed only one brake component at a time in the following sequence: master cylinder
- combination valve
- right rear wheel
- left rear wheel
- right front wheel
- left front wheel
MANUAL BLEEDING
1. Remove reservoir filler caps and fill reservoir with Mopar, or equivalent quality DOT 3 brake fluid.
2. If calipers, or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws.
Then close each bleed screw as fluid starts to
drip from it. Top off master cylinder reservoir once more before proceeding.
Bleed Hose Setup
3. Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially
filled with brake fluid. Be sure end of bleed hose is
immersed in fluid.
4. Open up bleeder, then have a helper press down the brake pedal. Once the pedal is down close
the bleeder. Repeat bleeding until fluid stream is
clear and free of bubbles. Then move to the next wheel.
PRESSURE BLEEDING
Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the
tank manufacturers pressure recommendations. Generally, a tank pressure of 15 - 20 psi is
sufficient for bleeding.
Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to
leakage, or drawing air back into the system. Use adapter provided with the equipment or Adapter
6921 or equivalent.

Brake Warning Indicator: Description and Operation General Information
SYSTEM OPERATION
The brake warning lamp gives an indication when the parking brake is applied, when the pressures
in the two halves of the split brake hydraulic system are unequal, if the Anti-lock Brake System
(ABS) lamp has failed and an ABS fault occurs, and during ABS diagnostics. The lamp is turned on
by the instrument cluster circuitry for about two seconds when the ignition switch is moved to the
Start position as a bulb test. After the bulb test, the lamp is controlled by a hard wired input from
the parking brake switch and/or by the instrument cluster circuitry based upon messages received
from the Controller Anti-lock Brake (CAB) on the Chrysler Collision Detection (CCD) data bus.
The CAB turns the lamp on or off based upon the results of the ABS self-tests. The CAB
continually monitors the ABS circuits and sensors, including the brake warning switch and the ABS
lamp, to decide whether the system is in good operating condition. The CAB then sends the proper
messages to the instrument cluster on the CCD data bus to turn the lamp on or off. If the CAB turns
the lamp on after the bulb test, it indicates that the CAB has detected a system malfunction.
The parking brake switch is hard wired to the instrument cluster and closes to ground when the
parking brake is applied. The brake warning switch is hard wired to the CAB and closes to ground
when it senses unequal hydraulic pressures in the two halves of the split brake hydraulic system,
possibly due to low brake fluid level or brake fluid leakage.
After the bulb test, if the red brake warning lamp remains illuminated with the parking brake
released, the base brake system may not be operational. The vehicle should never be operated
while the red brake warning lamp is illuminated.

Brake Warning Indicator: Description and Operation Brake Warning Lamp Description
The red brake warning lamp is used to alert the driver of a hydraulic fault or that the parking brake
is applied. For the RWAL system, the red brake warning lamp also is used to alerts the driver of a
problem with the RWAL system.
The brake warning lamp illuminates when a message is sent over the bus to the cluster to
illuminate the bulb. A ground for the bulb is provided when:
- The brakes are applied and the park brake switch is actuated.
- A hydraulic fault has occurred and the pressure differential switch is actuated.
- A RWAL fault has occurred.

Brake Rotor/Disc: Testing and Inspection
GENERAL INFORMATION
The rotor braking surfaces should not be refinished unless necessary
Light surface rust and scale can be removed with a lathe equipped with dual sanding discs. The
rotor surfaces can be restored by machining in a disc brake lathe if surface scoring and wear are
light.
Replace the rotor under the following conditions: severely scored
- tapered
- hard spots
- cracked
- below minimum thickness
ROTOR MINIMUM THICKNESS
Measure rotor thickness at the center of the brake shoe contact surface. Replace the rotor if worn
below minimum thickness, or if machining would reduce thickness below the allowable minimum.
Rotor minimum thickness is usually specified on the rotor hub. The specification is either stamped
or cast into the hub surface.
ROTOR RUNOUT
Checking Rotor Runout And Thickness Variation
Check rotor lateral runout with dial indicator C-3339 or equivalent. Excessive lateral runout will
cause brake pedal pulsation and rapid, uneven wear of the brake shoes. Position the dial indicator
plunger approximately 25.4 min (1 inch) inward from the rotor edge. Maximum allowable rotor
runout is 0.102 mm (0.004 inch).
ROTOR THICKNESS VARIATION
Variations in rotor thickness will cause pedal pulsation, noise and shudder.
Measuring Rotor Thickness
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component
Information > Specifications > Page 4273
Measure rotor thickness at 6 to 12 points around the rotor face.
Position the micrometer approximately 25.4 mm (1 inch) from the rotor outer circumference for
each measurement.
Thickness should not vary by more than 0.013 mm (0.0005 inch) from point-to-point on the rotor.
Machine or replace the rotor if necessary.

Brake Rotor/Disc: Service and Repair Rotor Refinishing
Rotor braking surfaces can be sanded or machined in a disc brake lathe.
Fig 6 Refacing Brake Disc
The lathe must machine both sides of the rotor simultaneously with dual (two) cutter heads.
Equipment capable of machining only one side at a time will produce a tapered rotor.
Fig 7 Refacing Brake Disc -- Final Finish
The lathe should also be equipped with a grinder attachment or dual sanding discs for final cleanup
or light refinishing.
If the rotor surfaces only need minor cleanup of rust, scale, or minor scoring, use abrasive discs to
clean up the rotor surfaces. However, when a rotor is scored or worn, machining with cutting tools
will be required.
CAUTION: Do not machine the rotor if it will cause the rotor to fall below minimum allowable
thickness.

Brake Drum: Testing and Inspection
GENERAL INFORMATION
The maximum allowable diameter of the drum braking surface is indicated on the drum outer edge.
Generally, a drum can be machined to a maximum of 1.52 mm (0.060 inch) oversize. Always
replace the drum if machining would cause drum diameter to exceed the size limit indicated on the
drum.
BRAKE DRUM RUNOUT
Measure drum diameter and runout with an accurate gauge. The most accurate method of
measurement involves mounting the drum in a brake lathe and checking variation and runout with a
dial indicator.
Variations in drum diameter should not exceed 0.076 mm (0.003 inch). Drum runout should not
exceed 0.20 mm (0.008 inch) out of round. Machine the drum if runout or variation exceed these
values. Replace the drum if machining causes the drum to exceed the maximum allowable
diameter.

NOTE:
THIS INFORMATION APPLIES TO VEHICLES BUILT BEFORE JAN 16, 1998 MDH (0116XX)
EQUIPPED WITH GASOLINE ENGINES AND A 42/44/46 OR 47RE TRANSMISSION.
SYMPTOM/CONDITION:
Some vehicles may experience bucking during wide open throttle (WOT) acceleration. The bucking
occurs at approximately 5300 RPM. This condition may be caused by reaching the high RPM fuel
shut off rev limit before the transmission can shift into the next higher gear and is most likely to
occur with high electrical loads (high beams on, heated back lite, heated seats, radio, HVAC blower
on MAX etc.). During high current demands, the generator may emit electrical noise that can affect
the transmission governor pressure sensor output. If this occurs, the transmission may not shift
properly to the next higher gear under (WOT) acceleration conditions and therefore reach the fuel
shut off rev limiter. This may be seen most often between the 2-3 shift but can also be experienced
between the 1-2 shift.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual,
verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes
(DTC's) are present, record them on the repair order and repair as necessary before proceeding
further with this bulletin.
NOTE:
ONLY PERFORM THE FOLLOWING PROCEDURE SAFELY ON A HIGHWAY OR ROAD
OBEYING ALL POSTED SPEED LIMITS AND LAWS.
Attempt to duplicate the condition by switching on all accessory loads and driving the vehicle with
WOT accelerations through a shift sequence to see if the engine will reach the fuel shut off rev
limiter before the 2-3 or 1-2 shift is made.
If the bucking condition is experienced at approximately 5300 RPM before making the appropriate
upshifts, switch off all electrical loads and repeat the procedure. Repeat the procedure with the
electrical loads on and off a second time. If the bucking occurs with the electrical loads on and
does not occur with the loads off, perform the Repair Procedure.
PARTS REQUIRED:
1 56041403AA Sensor, Governor Pressure
REPAIR PROCEDURE:
This bulletin involves installing a newly designed governor pressure sensor.

The relay terminal numbers can be found on the bottom of the relay:
- Terminal number 30 is connected to battery voltage and can be switched or B+ (hot) at all times.
- The center terminal number 87A is connected (a circuit is formed) to terminal 30 in the
de-energized (normally OFF) position.
- Terminal number 87 is connected (a circuit is formed) to terminal 30 in the energized (ON)
position. Terminal number 87 then supplies battery voltage to the component being operated.
- Terminal number 86 is connected to a switched (+) power source.
- Terminal number 85 is grounded by the Powertrain Control Module (PCM).
TESTING
1. Remove relay before testing. 2. Using an ohmmeter, perform a resistance test between
terminals 85 and 86.
- Resistance value (ohms) should be 75 +/- 5 ohms for resistor equipped relays.
3. Connect the ohmmeter between terminals number 87A and 30.
- Continuity should be present at this time.
4. Connect the ohmmeter between terminals number 87 and 30.
- Continuity should not be present at this time.
5. Use a set of jumper wires (16 gauge or smaller).
- Connect one jumper wire between terminal number 85 (on the relay) to the ground side (-) of a 12
volt power source.
6. Attach the other jumper wire to the positive side (+) of a 12V power source.
- Do not connect this jumper wire to relay at this time.
CAUTION: Do not allow the ohmmeter to contact terminals 85 or 86 during these tests. Damage to
ohmmeter may result.
7. Attach the other jumper wire (12V +) to terminal number 86. This will activate the relay.
- Continuity should now be present between terminals number 87 and 30.
- Continuity should not be present between terminals number 87A and 30.
8. Disconnect jumper wires from relay and 12 volt power source.
If continuity or resistance tests did not pass, replace relay.

Wheel Cylinder: Service and Repair Cleaning and Inspection
CLEANING
Clean the cylinder and pistons with clean brake fluid or brake cleaner only. Do not use any other
cleaning agents.
Dry the cylinder and pistons with compressed air. Do not use rags or shop towels to dry the
cylinder components. Lint from cloth material will adhere to the cylinder bores and pistons.
INSPECTION
Inspect the cylinder bore. Light discoloration and dark stains in the bore are normal and will not
impair cylinder operation.
The cylinder bore can be lightly polished but only with crocus cloth. Replace the cylinder if the bore
is scored, pitted or heavily corroded. Honing the bore to restore the surface is not recommended.
Inspect the cylinder pistons. The piston surfaces should be smooth and free of scratches, scoring
and corrosion. Replace the pistons if worn, scored, or corroded. Do attempt to restore the surface
by sanding or polishing.
Discard the old piston cups and the spring and expander. These parts are not reusable. The
original dust boots may be reused but only if they are in good condition.

Brake Bleeding: Service and Repair Antilock Brake System Bleeding Procedures
W/ Four Wheel Antilock Brakes
ABS system bleeding requires conventional bleeding methods plus use of the DRB scan tool. The
procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and
bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to
remove any air remaining in the system.
1. Perform base brake bleeding. 2. Connect scan tool to the Data Link Connector. 3. Select
ANTILOCK BRAKES, followed by MISCELLANEOUS, then BLEED BRAKES. Follow the
instructions displayed. When scan tool
displays TEST COMPLETE, disconnect scan tool and proceed.
4. Perform base brake bleeding a second time. 5. Top off master cylinder fluid level and verify
proper brake operation before moving vehicle.
W/ Rear Wheel Antilock Brakes
GENERAL INFORMATION
RWAL brake bleeding can be performed manually, or with pressure bleeding equipment.
Use Mopar DOT 3 brake fluid, or an equivalent meeting SAE J1703-F and DOT 3 standards, to fill
and bleed the brake system.
Bleed only one brake component at a time. Recommended bleed sequence is: master cylinder
- combination valve
- rear antilock valve
- left rear wheel
- right rear wheel
- right front wheel
- left front wheel
MANUAL BLEEDING
Use a bleed hose at each caliper/cylinder bleed screw. Attach one end of the hose to the bleed
screw and insert the opposite end in glass container partially filled with brake fluid. A glass
container makes it easier to see air bubbles as they exit the bleed hose. Be sure the end of the
bleed hose remains immersed in fluid. This prevents air from being drawn back into the system.
Do not allow the master cylinder to run out of fluid when bleeding the brakes. An empty cylinder will
allow air to be drawn back into the system. Check fluid level frequently during bleeding operations.
Be sure to tighten each brake line fitting, or bleed screw once bleeding is completed. Loose fittings
and bleed screws allows air to enter the system.
PRESSURE BLEEDING
If pressure bleeding equipment will be used, the front brake metering valve will have to be held
open to bleed the front brakes. The valve stem is located in the forward end of the combination
valve. The stem must either be pressed inward, or held outward slightly. a spring clip tool or helper
is needed to hold the valve stem in position.
Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the
tank manufacturers pressure recommendations. Generally, a tank pressure of 15 - 20 psi is
sufficient for bleeding.
Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to
leakage, or drawing air back into the system.

Brake Bleeding: Service and Repair Base Brake System Bleeding
GENERAL INFORMATION
Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards
only. Use fresh, clean fluid from a sealed container at all times.
Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into
small bubbles that are distributed throughout the hydraulic system. This will make additional
bleeding operations necessary.
Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will
allow additional air to be drawn into the system. Check the cylinder fluid level frequently and add
fluid as needed.
Bleed only one brake component at a time in the following sequence: master cylinder
- combination valve
- right rear wheel
- left rear wheel
- right front wheel
- left front wheel
MANUAL BLEEDING
1. Remove reservoir filler caps and fill reservoir with Mopar, or equivalent quality DOT 3 brake fluid.
2. If calipers, or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws.
Then close each bleed screw as fluid starts to
drip from it. Top off master cylinder reservoir once more before proceeding.
Bleed Hose Setup
3. Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially
filled with brake fluid. Be sure end of bleed hose is
immersed in fluid.
4. Open up bleeder, then have a helper press down the brake pedal. Once the pedal is down close
the bleeder. Repeat bleeding until fluid stream is
clear and free of bubbles. Then move to the next wheel.
PRESSURE BLEEDING
Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the
tank manufacturers pressure recommendations. Generally, a tank pressure of 15 - 20 psi is
sufficient for bleeding.
Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to
leakage, or drawing air back into the system. Use adapter provided with the equipment or Adapter
6921 or equivalent.

Brake Fluid: Testing and Inspection
CAUTION:
The hydraulic fluid used in automotive brake systems is hygroscopic. This means that the hydraulic
fluid tends to absorb moisture from the atmosphere over periods of time. As hydraulic brake fluid
absorbs moisture, it effects the function of the vehicles hydraulic brake system. For this reason, the
vehicle's hydraulic brake fluid should be drained and replaced using fresh clean hydraulic brake
fluid every two years. When replacing hydraulic brake fluid, use only Mopar brake fluid or an
equivalent from a sealed container. Brake fluid must conform to DOT 3 specifications.
BRAKE FLUID CONTAMINATION
Indications of fluid contamination are swollen or deteriorated rubber parts. Swelling indicates the
presence of petroleum in the brake fluid.
To test for contamination, put a small amount of drained brake fluid in clear glass jar. If the fluid
separates into layers, there is mineral oil or other fluid contamination of the brake fluid.
If the brake fluid is contaminated, drain and thoroughly flush the brake system. Replace all the
rubber parts or components containing rubber coming into contact with the brake fluid. This
includes the master cylinder, proportioning valves, caliper seals, wheel cylinder seals, ABS
hydraulic control unit (HCU), and all hydraulic fluid hoses.

Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Hose/Line > Component
Information > Description and Operation > Page 4383
Brake Hose/Line: Testing and Inspection
Flexible rubber hose is used at both front brakes and at the rear axle junction block. Inspect the
hoses whenever the brake system is serviced, at every engine oil change, or whenever the vehicle
is in for service. Inspect the hoses for surface cracking, scuffing, or worn spots. Replace any brake
hose immediately if the fabric casing of the hose is exposed due to cracks or abrasions.
Also check brake hose installation. Faulty installation can result in kinked, twisted hoses, or contact
with the wheels and tires or other chassis components. All of these conditions can lead to scuffing,
cracking and eventual failure.
The steel brake lines should be inspected periodically for evidence of corrosion, twists, kinks,
leaks, or other damage. Heavily corroded lines will eventually rust through causing leaks. In any
case, corroded or damaged brake lines should be replaced.
Factory replacement brake lines and hoses are recommended to ensure quality, correct length and
superior fatigue life. Care should be taken to make sure that brake line and hose mating surfaces
are clean and free from nicks and burrs. Also remember that right and left brake hoses are not
interchangeable.
Use new copper seal washers at all caliper connections. Be sure brake line connections are
properly made (not cross threaded) and tightened to recommended torque.

Brake Proportioning/Combination Valve: Description and Operation
GENERAL INFORMATION
The combination valve contains a pressure differential valve and switch, metering valve and a
proportioning valve on 1500 models. The combination valve/ rear brake proportioning valve are not
repairable and must be replaced as an assembly.
PRESSURE DIFFERENTIAL SWITCH
The pressure differential switch is connected to the brake warning lamp. The switch is triggered by
movement of the switch valve. The purpose of the switch is to monitor fluid pressure in the
separate front/rear brake hydraulic circuits.
A decrease or loss of fluid pressure in either hydraulic circuit will cause the switch valve to shuttle
forward or rearward in response to the pressure differential. Movement of the switch valve will push
the switch plunger upward. This closes the switch internal contacts completing the electrical circuit
to the warning lamp. The switch valve may remain in an actuated position until repair restores
system pressures to normal levels.
METERING VALVE
The metering valve is used to balance brake action between the front disc and rear drum brakes.
The valve holds-off the initial pressure to the front disc brakes until the rear brake shoes retracting
springs are overcome. The valve is designed to maintain front brake fluid pressure at 241 - 517
kPa (35 - 75 psi) until the hold-off limit of 310 - 689 kPa (100 psi) is reached. At this point, the
metering valve opens completely permitting full fluid apply pressure to the front disc brakes. This
reduces front brake lining wear during low deceleration stops.
PROPORTIONING VALVE
The proportioning valve is used to balance front-rear brake action at high decelerations. The valve
allows normal fluid flow during moderate braking. The valve only controls fluid flow during high
decelerations brake stops, when a percentage of rear weight is transferred to the front wheels.

Brake Proportioning/Combination Valve: Testing and Inspection
METERING VALVE
Metering valve operation can be checked visually with the aid of a helper. Observe the metering
valve stem while a helper applies and releases the brakes. If the valve is operating correctly, the
stem will extend slightly when the brakes are applied and retract when the brakes are released. If
the valve is faulty, replace the entire combination valve as an assembly.
PRESSURE DIFFERENTIAL SWITCH
1. Have helper sit in drivers seat to apply brake pedal and observe red brake warning light. 2.
Raise vehicle on hoist. 3. Connect bleed hose to a rear wheel cylinder and immerse hose end in
container partially filled with brake fluid. 4. Have helper press and hold brake pedal to floor and
observe warning light.
a. If warning light illuminates, switch is operating correctly. b. If light fails to illuminate, check circuit
fuse, bulb, and wiring. The parking brake switch can be used to aid in identifying whether or not the
brake light bulb and fuse is functional. Repair or replace parts as necessary and test differential
pressure switch operation again.
5. If warning light still does not illuminate, switch is faulty. Replace combination valve assembly,
bleed brake system and verify proper switch and
valve operation.
PROPORTIONING VALVE
Road test the vehicle and make several hard brake applications. If a premature rear wheel skid
occurs this could be an indication the proportioning valve has malfunctioned. 1. Inspect and verify
the rear brakes are clean, adjusted and operating properly. 2. Check the pressure in and out of the
valve. The pressure should be equal up to the 250 psi. split point. 3. Above 250 psi. the output
pressure should decrease on a 0.43 slope.

Hydraulic Control Assembly - Antilock Brakes: Description and Operation General Information
The controller-antilock brake module is used to monitor wheel speeds and modulates (control)
hydraulic pressure in each brake channel. The modulated hydraulic pressure is used to prevent
wheel lock up during braking. The CAB also provides a vehicle speed signal (VSS) to the
powertrain control module.

Hydraulic Control Assembly - Antilock Brakes: Description and Operation Hydraulic Control Unit
(HCU)
Description
The HCU on the EBC 2 has only a separate rear valve body.
The HCU on the EBC 325 has two integral valve bodies for controlling the front and rear brakes.
Within the HCU are solenoids, valves, check valves, and a reset switch necessary to apply and
release brake pressure as required to avoid wheel lockup, keep the wheels rolling, and maintain
optimum deceleration.
The isolation valve is normally open, allowing unrestricted flow from the master cylinder to the
wheels. When the CAB determines antilock intervention is required, the valve closes to isolate the
master cylinder hydraulic circuit. Fluid is trapped in the circuit and then prevented from reaching the
wheels.
The dump valve is pulsed on and off by the CAB. This valve cycles only if the isolation valve is
closed. When dump is on, it allows fluid to the low pressure accumulator for temporary storage.
This causes the pressure to the wheel to decrease. When the valve is off, fluid is allowed to the
wheel.
The brake return check valve allows the HCU to drain faster after the ABS stop, when the brake is
released.
The Reset Switch is positioned in the HCU to monitor the master cylinder (input), rear brake
(output) and accumulator pressure. During normal braking, pressure is equal for input and output
and the switch remains open. During an Antilock stop the switch will close as the isolation valve is
cycled and pressure becomes unequal between input and output. At the end of an ABS stop the
isolation valve will open as master cylinder pressure and rear pressure equalize. The switch is
used to monitor correct operation of the HCU and to set a diagnostic trouble code if incorrect
pressure is detected.
When the brakes are applied, fluid is forced from the master cylinder outlet ports to the HCU inlet
ports. This pressure is transmitted through three normally open isolation valves inside the HCU,
then through the outlet ports of the HCU to the wheels. If the CAB senses that a wheel is about to
lock, based on wheel speed sensor data, it pulls the normally open isolation valve closed for that
circuit. This prevents any more fluid from entering that circuit. The CAB continues to look at the
sensor signal to determine if the wheel is still decelerating. If deceleration is still taking place, the
normally closed dump valve for that circuit is opened. This dumps any pressure that is trapped
between the normally open valve and the brake back into an accumulator. Once the affected circuit
comes back up to speed, the CAB returns the valves to their normal condition allowing the affected
brake to be reapplied. On the EBC 325 system, the pump and accumulators are used to provide
rapid response during the reapply sequence and to minimize pedal feedback.
With Four Wheel Antilock Brakes
GENERAL INFORMATION
CAB/HCU
The Hydraulic Control Unit (HCU) consists of a valve body, pump, accumulator and motor.
The pump, motor, and accumulator are combined into an assembly attached to the valve body. The
accumulator store the extra fluid which had to be dumped from the brakes. This is done to prevent
the wheels from locking up. The pump provides the fluid volume needed and is operated by a DC
type motor. The motor is controlled by the Controller Antilock Brake (CAB).
The valve body contains the solenoid valves. The valves modulate brake pressure during antilock
braking and are controlled by the CAB.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Hydraulic Control Assembly Antilock Brakes > Component Information > Description and Operation > General Information > Page 4401
The HCU provides three channel pressure control to the front and rear brakes. One channel
controls the rear wheel brakes in tandem. The two remaining channels control the front wheel
brakes individually.
During antilock braking, the solenoid valves are opened and closed as needed. The valves are not
static. They are cycled rapidly and continuously to modulate pressure and control wheel slip and
deceleration.
During normal braking, the HCU solenoid valves and pump are not activated. The master cylinder
and power booster operate the same as a vehicle without an ABS brake system.
During antilock braking, solenoid valve pressure modulation occurs in three stages, pressure
decrease, pressure hold, and pressure increase. The valves are all contained in the valve body
portion of the HCU.
Pressure Decrease The inlet valve is closed and the outlet valve is opened during the pressure
decrease cycle.
A pressure decrease cycle is initiated when speed sensor signals indicate high wheel slip at one or
more wheels. At this point, the CAB closes the inlet to prevent the driver from further increasing the
brake pressure and locking the brakes. The CAB then opens the outlet valve, which also opens the
return circuit to the accumulators. Fluid pressure is allowed to bleed off (decrease) as needed to
prevent wheel lock.
Once the period of high wheel slip has ended, the CAB closes the outlet valve and begins a
pressure increase or hold cycle as needed.
Pressure Hold Both solenoid valves are closed in the pressure hold cycle. Fluid apply pressure in
the control channel is maintained at a constant rate. The CAB maintains the hold cycle until sensor
inputs indicate a pressure change is necessary.
Pressure Increase The inlet valve is open and the outlet valve is closed during the pressure
increase cycle. The pressure increase cycle is used to counteract unequal wheel speeds. This
cycle controls re-application of fluid apply pressure due to changing road surfaces or wheel speed.
With Rear Wheel Antilock Brakes
If the Controller Antilock Brake (CAB) senses that rear wheel speed deceleration is excessive, it
will energize a isolation solenoid by providing battery voltage to the solenoid. This prevents a
further increase of driver induced brake pressure to the rear wheels. If this initial action is not
enough to prevent rear wheel lock-up, the CAB will momentarily energize a dump solenoid (the
CAB energizes the dump solenoid by providing battery voltage to the solenoid). This opens the
dump valve to vent a small amount of isolated rear brake pressure to an accumulator. The action of
fluid moving to the accumulator reduces the isolated brake pressure at the wheel cylinders. The
dump (pressure venting) cycle is limited to very short time periods (milliseconds). The CAB will
pulse the dump valve until rear wheel deceleration matches the vehicle deceleration rate or the
desired slip rate programmed into the CAB. The system will switch to normal braking once wheel
locking tendencies are no longer present.
A predetermined maximum number of consecutive dump cycles can be performed during any one
antilock stop. If excessive dump cycles occur, a DTC will be set and stored in the CAB memory. If
during an antilock stop, the driver releases the brake pedal, the reset switch contacts will open.
This signal to the CAB is an indication that pressure has equalized across the RWAL valve. The
CAB will then reset the dump cycle counter in anticipation of the next antilock stop. Additionally,
any fluid stored in the accumulator will force its way past the dump valve, back into the hydraulic
circuit and return to the master cylinder.
A fuse internal to the CAB, provides a fail-safe device which prevents unwanted control over the
isolation and dump solenoids. The fuse is in series with the isolation and dump solenoids output
circuits. If the internal fuse is open, the CAB cannot provide voltage to energize either solenoid and
antilock stops are prevented. If the fuse is open, the braking system will operate normally but
without antilock control over rear brake pressure.

Brake Master Cylinder: Description and Operation
A two-piece master cylinder is used on all models. The cylinder body containing the primary and
secondary pistons is made of aluminum. The removable fluid reservoir is made of nylon reinforced
with glass fiber. The reservoir is the only serviceable component.
The fluid compartments of the nylon reservoir are interconnected to permit fluid level equalization.
However, the equalization feature does not affect circuit separation in the event of a front or rear
brake malfunction. The reservoir compartments will retain enough fluid to operate the functioning
hydraulic circuit.
Care must be exercised when removing/installing the master cylinder connecting lines. The threads
in the cylinder fluid ports can be damaged if care is not exercised. Start all brake line fittings by
hand to avoid cross threading.
The cylinder reservoir can be replaced when necessary. However, the aluminum body section of
the master cylinder is not a repairable component.
NOTE: If diagnosis indicates that an internal malfunction has occurred, the aluminum body section
must be replaced as an assembly.

Vacuum Brake Booster: Description and Operation
Power assisted brakes are standard on all models. A dual diaphragm, vacuum operated power
brake booster is used to provide assist.
The booster unit consists of a single housing divided into separate chambers by two internal
diaphragms. The outer edge of the diaphragm is secured to the housing.
The booster push rod, which connects the booster to the brake pedal and master cylinder, is
attached to the center of the diaphragm. A check valve is used in the booster inlet and is connected
to the engine intake manifold. Power assist is generated utilizing a combination of vacuum and
atmospheric pressure to boost brake assist.
NOTE: The power brake booster is not a repairable component. The booster must be replaced as
an assembly if diagnosis indicates a malfunction has occurred.

Module Corrosion
DEFECT: On some van and wagon model vehicles equipped with 4-wheel antilock brake systems
(ABS), aftermarket batteries may leak electrolyte onto the ABS control module connector, which
can compromise the sealing integrity of the connector. This may allow development of a short
circuit in the connector, which could eventually lead to a fire.
REMEDY: Dealers will inspect the ABS control module connector for electrolyte damage and
replace the connector as necessary. The manufacturer has not yet provided an owner notification
for this campaign. Owners may contact DaimlerChrysler at 1-800-853-1403.

DEFECT: On some van and wagon model vehicles equipped with 4-wheel antilock brake systems
(ABS), aftermarket batteries may leak electrolyte onto the ABS control module connector, which
can compromise the sealing integrity of the connector. This may allow development of a short
circuit in the connector, which could eventually lead to a fire.
REMEDY: Dealers will inspect the ABS control module connector for electrolyte damage and
replace the connector as necessary. The manufacturer has not yet provided an owner notification
for this campaign. Owners may contact DaimlerChrysler at 1-800-853-1403.

CAB/HCU
The Controller Antilock Brake (CAB) is mounted on the top of the hydraulic control unit.
The CAB operates the ABS system and is separate from other vehicle electrical circuits. CAB
voltage source is through the ignition switch in the RUN position.
The CAB contains dual microprocessors. A logic block in each microprocessor receives identical
sensor signals. These signals are processed and compared simultaneously.
The CAB contains a self check program that illuminates the ABS warning light when a system fault
is detected. Faults are stored in a diagnostic program memory and are accessible with the DRB
scan tool.
ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50
times. Stored faults are not erased if the battery is disconnected.
NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be
programed into the new CAB.

GENERAL INFORMATION
RWAL Controller Antilock Brake (CAB)
The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and
controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics.
- Monitors the RWAL brake system for proper operation.
- Controls the RWAL valve solenoids.
NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be
programed into the new CAB.
SYSTEM SELF-TEST
When the ignition switch is turned-on the microprocessor RAM and ROM are tested. If an error
occurs during the test a Diagnostic Trouble Code (DTC) will be set into the RAM memory. However
it is possible the DTC will not be stored in memory if the error has occurred in the RAM module
were the DTC's are stored. Also it is possible a DTC may not be stored if the error has occurred in
the ROM which signals the RAM to store the DTC.
CAB INPUTS
The CAB continuously monitors the speed of the differential ring gear by monitoring signals
generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency when it
recognizes the ring gear decelerating too rapidly. The CAB monitors the following inputs to
determine when a wheel locking tendency may exists: -
Rear Wheel Speed Sensor
- Brake Lamp Switch
- Brake Warning Lamp Switch
- Reset Switch
- 4WD Switch (If equipped)
CAB OUTPUTS
The CAB controls the following outputs for antilock braking and brake warning information: RWAL Valve
- ABS Warning Lamp
- Brake Warning Lamp

4WD Switch: Description and Operation
Vehicles equipped with four wheel drive (4WD) have an indicator switch mounted on the front axle
assembly. This switch is closed to ground when the transfer case is shifted to four wheel drive
mode and the engine is running on some vehicles. While in four wheel drive, the front and rear
axles will operate together. With this input, the CAB is able to modify its operation to allow for 4WD
operation. Should a need for antilock operation occur while in four wheel drive, the CAB will extend
the amount of allowable dump cycles.

OPERATION
The ABS brake system uses 3 wheel speed sensors. A sensor is mounted to each front steering
knuckles. The third sensor is mounted on top of the rear axle differential housing. The sensor is a
magnet coil that is mounted over a tone wheel front/exciter ring rear with an air gap between them.
The sensors measure the wheel speed by monitoring the rotation of the tone wheels front/exciter
ring rear. As the teeth of the tone wheels front/exciter ring rear move through the magnetic field of
the sensor an AC voltage is generated. This signal frequency increases or decreases proportionally
to the speed of the wheel. The Controller Antilock Brake (CAB) monitors these signals for changes
in wheel deceleration. If the CAB detects a sudden wheel or wheels deceleration within a
predetermined amount the CAB will activate the ABS system.
CIRCUIT OPERATION
The all wheel Anti-Lock Brake System (ABS) uses three wheel speed sensors; a single sensor for
both rear wheels and individual sensors for the front wheels. The single sensor used for the rear
wheels mounts on the top of the rear axle differential housing. Each sensor converts wheel speed
into an electrical signal that is transmitted to the Controller Anti-Lock Brakes (CAB). A pair of
twisted wires connect to each sensor and provide signals to the CAB.
Circuits B6 and B7 provide signals to the CAB from the right front wheel speed sensor. Circuit B6,
which provides the LOW signal, connects to cavity 15 of the CAB. Circuit B7 connects to cavity 2 of
the CAB and provides the HIGH signal.
Circuits B8 and B9 provide signals to the CAB from the left front wheel speed sensor. Circuit B8,
which provides the LOW signal, connects to cavity 16 of the CAB. Circuit B9 connects to cavity 3
and provides the HIGH signal.
Circuit B114 connects to cavity 14 of the CAB and to circuit B2 of the rear wheel speed sensor
harness at the sensor connector. Circuit B113 connects to cavity 1 of the CAB and to circuit B1 at
the rear wheel speed sensor harness connector. Circuit B114 provides the rear wheel speed
sensor LOW input while circuit B113 provides the HIGH input.

Wheel Speed Sensor: Description and Operation Kelsey-Hayes Antilock Brake Systems
The EBC 325 ABS system uses one wheel speed sensor on each front wheel, and one speed
sensor mounted in the rear axle for the rear wheels.
The RWAL II uses only one speed sensor mounted in the rear axle for the rear wheels.
The sensor measures the wheel speed by monitoring a rotating tone wheel. The signal generated
by the sensor and tone wheel is transmitted to the CAB.
Each sensor has:
- a metal tone wheel with teeth on its outside diameter
- a magnetic/coil pick-up (speed sensor) that is mounted to a fixed component
- an air gap between the tone wheel and the speed sensor assembly
As the teeth of the tone wheel move through the magnetic field of the sensor, an AC voltage is
generated. This signal frequency increases or decreases proportionally to the speed of the wheel.
The CAB monitors this signal to check for a sudden change in single or multiple wheel
decelerations. If the deceleration of one or more wheels is not within a predetermined amount, the
antilock module takes control.
Diagnostically, the coil of wheel speed sensors have different amounts of resistance based upon
the sensor type. When measured across the connector two terminals, the resistance should be:
AN, DN, BE and BR:
4x4 front sensors 945-1155 ohms
AB, AN and DN:
4x2 front sensors 2500-2955 ohms
BE and BR:
4x2 front sensors 1000-1250 ohms
AB, AN, DN, BE and BR:
All rear sensors 1600-2300 ohms
NOTE: For all resistance ranges add 30% to the value for extreme heat, subtract 30% for extreme
cold.)
The rear wheel speed sensor used on all vehicles have the same resistance value, but there are
two different sensors. Therefore, it is important to replace the rear wheel speed sensor with the
proper part.
On a EBC 325 system each front wheel speed is monitored through the speed sensor mounted at
the wheel end of the hub. On a EBC 325 and RWAL II system the rear wheel speed is monitored
through the speed sensor mounted in the rear axle assembly.
The CAB will disable antilock control, illuminate the ABS warning light circuit via COD, and store
trouble codes if it detects a problem with any or all of the wheel speed sensors:
- incorrect circuit resistance when checked with no vehicle movement
- incorrect sensor output during vehicle movement
- erratic sensor output during vehicle movement

Alternator: Description and Operation
SYSTEM OPERATION
The generator is belt-driven by the engine using a serpentine type drive belt. It is serviced only as a
complete assembly. If the generator fails for any reason, the entire assembly must he replaced.
As the energized rotor begins to rotate within the generator, the spinning magnetic field induces a
current into the windings of the stator coil. Once the generator begins producing sufficient current. it
also provides the current needed to energize the rotor.
The Y type stator winding connections deliver the induced AC current to 3 positive and 3 negative
diodes for rectification. From the diodes, rectified DC current is delivered to the vehicle electrical
system through the generator battery and ground terminals.
Although the generators appear the same externally, different generators with different output
ratings are used on this vehicle. Be certain that the replacement generator has the same output
rating and part number as the original unit. Refer to Generator Ratings in the Specifications for
amperage ratings and part numbers.
Noise emitting from the generator may be caused by: worn, loose or defective bearings; a loose or
defective drive pulley; incorrect, worn, damaged or misadjusted fan drive belt; loose mounting
bolts; a misaligned drive pulley or a defective stator or diode.

Description and Operation
Voltage Regulator: Description and Operation
SYSTEM OPERATION
The Electronic Voltage Regulator (EVR) is not a separate component. It is actually a voltage
regulating circuit located within the Powertrain Control Module (PCM). The EVR is not serviced
separately. If replacement is necessary, the PCM must be replaced.
Operation: The amount of DC current produced by the generator is controlled by EVR circuitry
contained within the PCM. This circuitry is connected in series with the generators second rotor
field terminal and its ground.
Voltage is regulated by cycling the ground path to control the strength of the rotor magnetic field.
The EVR circuitry monitors system line voltage and battery temperature (refer to Battery
Temperature Sensor for more information). It then compensates and regulates generator current
output accordingly. Also refer to Charging System Operation for additional information.

Description and Operation
Starter Motor: Description and Operation
SYSTEM OPERATION
The starter motor incorporates several features to create a reliable, efficient, compact, and
lightweight unit. A planetary gear system (intermediate transmission) is used between the electric
motor and the pinion gear. This feature makes it possible to reduce the dimensions of the starter.
At the same time, it allows higher armature rotational speed and delivers increased torque through
the pinion gear to the starter ring gear on the automatic transmission torque converter.
The starter motors for all engines are activated by a solenoid mounted to the overrunning clutch
housing. However, the starter motor and solenoid are serviced only as a complete assembly If
either component is faulty or damaged, the entire starter assembly must be replaced.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE

Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.

Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Auxiliary Power Outlet: Description and Operation
SYSTEM OPERATION
An accessory power outlet is optional equipment on this model. The power outlet is installed in the
instrument panel accessory switch plate, which is located near the center of the instrument panel,
inboard of the radio. The power outlet base is secured by a snap fit within the instrument panel
accessory switch plate. A plastic protective cap snaps into the power outlet base when the power
outlet is not being used.
The power outlet base or receptacle shell is connected to ground, and an insulated contact in the
bottom of the shell is connected to battery current. The power outlet receives battery voltage from a
fuse in the Power Distribution Center (PDC) at all times.
While the power outlet is very similar to a cigar lighter base unit, it does not include the two small
spring-clip retainers inside the bottom of the receptacle shell that are used to secure the cigar
lighter heating element to the insulated contact.
The power outlet receptacle unit and the accessory power outlet protective cap are available for
service. The power outlet receptacle cannot be repaired and, if faulty or damaged, it must be
replaced.

Component Information > Description and Operation
Electronic Noise Suppressor: Description and Operation
SYSTEM OPERATION
Radio Frequency Interference (RFI) and ElectroMagnetic Interference (EMI) noise suppression is
accomplished primarily through circuitry internal to the radio receivers. These internal suppression
devices are only serviced as part of the radio receiver. External suppression devices that are
serviced, and should be checked in the case of RFI or EMI noise complaints, include the following:
Radio antenna base ground
- Radio chassis ground wire, strap, or bracket
- Engine-to-body ground strap (if the vehicle is so equipped)
- Cab-to-bed ground strap (if the vehicle is so equipped)
- Heater core ground strap (if the vehicle is so equipped)
- Resistor-type spark plugs
- Radio suppression-type secondary ignition wiring.
In addition, if the source of RFI or EMI noise is identified as a component on the vehicle (i.e.,
generator, blower motor, etc.), the ground path for that component should be checked. If excessive
resistance is found in that circuit, repair that circuit as required before considering any component
replacement.
If the source of the noise is identified as two-way mobile radio or telephone equipment, check the
equipment installation for the following: Power connections should be made directly to the battery, and fused as closely to the battery as
possible.
- The antenna should be mounted on the roof or toward the rear of the vehicle. Remember that
magnetic antenna mounts on the roof panel can adversely affect the operation of an overhead
console compass, if the vehicle is so equipped.
- The antenna cable should be fully shielded coaxial cable, should be as short as is practical, and
should be routed away from the factory-installed vehicle wire harnesses whenever possible.
- The antenna and cable must be carefully matched to ensure a low Standing Wave Ratio (SWR).
Fleet vehicles are available with an extra-cost RFI suppressed Powertrain Control Module (PCM).
This unit reduces interference generated by the PCM on some radio frequencies used in two-way
radio communications. However, this unit will not resolve complaints of RFI in the commercial AM
or FM radio frequency ranges

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:

Multiple Junction Connector: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:

Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Auxiliary Power Outlet: Description and Operation
SYSTEM OPERATION
An accessory power outlet is optional equipment on this model. The power outlet is installed in the
instrument panel accessory switch plate, which is located near the center of the instrument panel,
inboard of the radio. The power outlet base is secured by a snap fit within the instrument panel
accessory switch plate. A plastic protective cap snaps into the power outlet base when the power
outlet is not being used.
The power outlet base or receptacle shell is connected to ground, and an insulated contact in the
bottom of the shell is connected to battery current. The power outlet receives battery voltage from a
fuse in the Power Distribution Center (PDC) at all times.
While the power outlet is very similar to a cigar lighter base unit, it does not include the two small
spring-clip retainers inside the bottom of the receptacle shell that are used to secure the cigar
lighter heating element to the insulated contact.
The power outlet receptacle unit and the accessory power outlet protective cap are available for
service. The power outlet receptacle cannot be repaired and, if faulty or damaged, it must be
replaced.

Description and Operation
Electronic Noise Suppressor: Description and Operation
SYSTEM OPERATION
Radio Frequency Interference (RFI) and ElectroMagnetic Interference (EMI) noise suppression is
accomplished primarily through circuitry internal to the radio receivers. These internal suppression
devices are only serviced as part of the radio receiver. External suppression devices that are
serviced, and should be checked in the case of RFI or EMI noise complaints, include the following:
Radio antenna base ground
- Radio chassis ground wire, strap, or bracket
- Engine-to-body ground strap (if the vehicle is so equipped)
- Cab-to-bed ground strap (if the vehicle is so equipped)
- Heater core ground strap (if the vehicle is so equipped)
- Resistor-type spark plugs
- Radio suppression-type secondary ignition wiring.
In addition, if the source of RFI or EMI noise is identified as a component on the vehicle (i.e.,
generator, blower motor, etc.), the ground path for that component should be checked. If excessive
resistance is found in that circuit, repair that circuit as required before considering any component
replacement.
If the source of the noise is identified as two-way mobile radio or telephone equipment, check the
equipment installation for the following: Power connections should be made directly to the battery, and fused as closely to the battery as
possible.
- The antenna should be mounted on the roof or toward the rear of the vehicle. Remember that
magnetic antenna mounts on the roof panel can adversely affect the operation of an overhead
console compass, if the vehicle is so equipped.
- The antenna cable should be fully shielded coaxial cable, should be as short as is practical, and
should be routed away from the factory-installed vehicle wire harnesses whenever possible.
- The antenna and cable must be carefully matched to ensure a low Standing Wave Ratio (SWR).
Fleet vehicles are available with an extra-cost RFI suppressed Powertrain Control Module (PCM).
This unit reduces interference generated by the PCM on some radio frequencies used in two-way
radio communications. However, this unit will not resolve complaints of RFI in the commercial AM
or FM radio frequency ranges

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.

Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

NUMBER: 19-07-00
GROUP: Steering
DATE: September 22, 2000
SUBJECT: Steering Wander Diagnosis
OVERVIEW: This bulletin provides a diagnostic procedure for steering wander.
MODELS: 1998-2001 (AB) Ram Van/Wagon
SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight
steering corrections are necessary to be able to keep the vehicle moving in a straight line.
Steering wander can be created by a number of different conditions including but not limited to the
following:
^ Non-factory installed options.
^ Tires or wheels of different size.
^ Aftermarket wheels.
^ Tires that have a belt that has shifted.
^ Incorrect tire pressure.
^ A vehicle that is carrying extra added weight (e.g. tool boxes).
^ Steering and/or suspension components that are worn or damaged.
^ Wheel bearings that are loose, worn, or damaged.
^ A vehicle that is not within alignment specifications.
NOTE:
UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS,
CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER.
The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering
system components are functioning as designed and are not the root cause of steering wander.
DIAGNOSIS:
1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may
cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to
exceed the front or rear Gross Axle Weight Rating (GAWR).
2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged
and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to
wander and should be replaced before continuing with the diagnosis.
3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove
box).
NOTE:
TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN
PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB
OR LIGHT LOAD CONDITIONS.
4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road
crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70
mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the
vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a
steering wander condition.
NOTE:
VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD
TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION
MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED
ROADS, ETC.).
5. Raise the vehicle on an appropriate lift.

6. Secure a dial indicator to the lower control arm. Position the dial indicator so that the tip of the
indicator contacts the inside face of the rotor (Figure 1).
7. Place your hands at the top and bottom of the tire/wheel assembly and push the tire/wheel
assembly inboard (Figure 2). Zero the dial indicator. With your hands at the top and bottom of the
tire/wheel assembly, pull the tire/wheel assembly outboard (Figure 3). Record the dial indicator
reading. Perform this procedure on both front wheel bearings and proceed to the next step if the
wheel bearing endplay exceeds 0.025 - 0.076 mm (0.001 - 0.003 in.). Proceed to Step 9 if
wheel-bearing endplay on both front wheel bearings are within specifications.
NOTE:
WHEEL BEARING INSPECTION AND ADJUSTMENT IS ONLY REQUIRED ON WHEEL
BEARINGS EXCEEDING 0.025 - 0.076 MM (0.001 - 0.003 IN.) ENDPLAY.
8. Remove the wheel bearing protective end cap, cotter pin, nut lock, nut, and washer from the
spindle. Inspect the wheel bearings. If it is determined that wheel bearing replacement is
necessary, refer to the appropriate Ram Van/Wagon Service Manual, Group 02, Wheel Bearings,
for removal and installation information. Reinstall the wheel bearings, washer, and adjustment nut if
the wheel bearings pass the inspection.
9. Using a torque wrench, tighten the wheel bearing adjustment nut to 54 N.m (40 ft. lbs.) while
rotating the tire/wheel assembly. Stop the wheel from rotating and loosen the nut. Using the
procedure identified in Steps 6 and 7 to measure endplay, adjust the front wheel bearing endplay
until 0.025 - 0.076 mm (0.001 - 0.003 in.) endplay has been achieved. Install the nut lock and a
new cotter pin.
10. Perform the Pre-Alignment inspection as identified in Group 02, Service Procedures, of the
appropriate Ram Van/Wagon Service Manual. Any worn steering and/or suspension component
must be replaced prior to performing an alignment.

Alignment: Description and Operation
GENERAL INFORMATION
Wheel Alignment Measurements
Wheel alignment involves the correct positioning of the wheels in relation to the vehicle. The
positioning is accomplished through suspension and steering linkage adjustments. An alignment is
considered essential for efficient steering, good directional stability and to minimize tire wear. The
most important measurements of an alignment are caster, camber and toe.
Caster - is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the
knuckle forward provides negative caster. Tilting the top of the knuckle rearward provides positive
caster. Positive caster promotes directional stability. This angle enables the front wheels to return
to a straight ahead position after turns.
Camber - is the inward or outward tilt of the wheel relative to the center of the vehicle. Tilting the
top of the wheel inward provides negative camber. Tilting the top of the wheel outward provides
positive camber. Incorrect camber will cause wear on the inside or outside edge of the tire.
Toe - is the difference between the leading inside edges and trailing inside edges of the front tires.
Uneven wheel toe position cause's unstable steering, uneven tire near and steering wheel
off-center. The wheel toe position is the final front wheel alignment adjustment.
Thrust Angle - is the angle of the rear axle relative to the centerline of the vehicle. Incorrect thrust
angle can cause off-center steering and excessive tire wear. This angle is not adjustable, damaged
component(s) must be replaced to correct the thrust angle.

Alignment: Testing and Inspection
PRE-ALIGNMENT INSPECTION
Before starting wheel alignment, the following inspection and necessary corrections must be
completed. 1. Inspect tires for size, air pressure and tread wear. 2. Inspect front wheel bearings for
wear or adjustment. 3. Inspect front wheels for excessive radial or lateral runout and balance. 4.
Inspect ball studs, linkage pivot points and steering gear for looseness, roughness or binding. 5.
Inspect suspension components for wear and noise.

Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins >
Page 4844
Alignment: Service and Repair
GENERAL INFORMATION
The front wheel alignment angles should be set to preferred specifications. This will prevent
abnormal tire tread wear.
Before each alignment reading the vehicle should be jounced (rear first, then front). Grasp each
bumper at the center and jounce the vehicle up and down several times. Always release the
bumper in the down position.
CAMBER AND CASTER
Camber and caster angle adjustments involve repositioning the upper suspension arm pivot bar.
Alignment adjustments are accomplished by changing the position of the pivot bar.
Adjuster Tool 8199, or equivalent is used to adjust the camber and caster angles.
Tools Attached To Frame
1. Clamp the tool on the upper suspension arm frame bracket. Use the two clamp bolts to attach
the tool to the bracket. 2. With the adjustment tools installed, loosen both upper suspension arm
bolts completely. 3. Tighten or loosen the tool adjustment bolts to move the upper suspension arm
inward or outward to obtain the proper camber and caster
angles.
Caster: Move the rear position of the pivot bar in or out. This will change the caster angle
significantly and camber angle only slightly. To retain the camber while adjusting caster, move the
rear pivot bar in or out. Move the forward pivot very slightly in the opposite direction.
NOTE: For example, to increase a positive caster angle move the rear position of the pivot bar
inward. Move the front of pivot bar outward until the original camber angle is obtained.
Camber: Move the forward position of the pivot bar in or out. This will change the camber angle
significantly and caster angle only slightly. The camber angle should be adjusted to the service
specifications. Tighten the pivot bar bolts to 298 Nm (220 ft. lbs.).

Page 4845
TOE POSITION
The wheel toe position is the final adjustment procedure. 1. Secure the steering wheel with the
front wheels in the straight ahead position. For power steering vehicles, start the engine before
straightening
the wheels.
2. Loosen the tie rod adjustment sleeve clamp bolts.
3. Adjust the wheel toe position by rotating the tie rod adjustment sleeve. 4. Position the adjustment
sleeve clamps so the ends are not located at the sleeve slot. Tighten the tie rod sleeve clamps to:
- Standard Duty: 23 Nm (17 ft. lbs.)
- Heavy Duty: 35 Nm (26 ft. lbs.)
Ensure the clamp bolts are located at the underside of the sleeve.
5. Verify camber, caster and toe position.

NOTE:
THIS INFORMATION APPLIES TO VEHICLES BUILT BEFORE JAN 16, 1998 MDH (0116XX)
EQUIPPED WITH GASOLINE ENGINES AND A 42/44/46 OR 47RE TRANSMISSION.
SYMPTOM/CONDITION:
Some vehicles may experience bucking during wide open throttle (WOT) acceleration. The bucking
occurs at approximately 5300 RPM. This condition may be caused by reaching the high RPM fuel
shut off rev limit before the transmission can shift into the next higher gear and is most likely to
occur with high electrical loads (high beams on, heated back lite, heated seats, radio, HVAC blower
on MAX etc.). During high current demands, the generator may emit electrical noise that can affect
the transmission governor pressure sensor output. If this occurs, the transmission may not shift
properly to the next higher gear under (WOT) acceleration conditions and therefore reach the fuel
shut off rev limiter. This may be seen most often between the 2-3 shift but can also be experienced
between the 1-2 shift.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual,
verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes
(DTC's) are present, record them on the repair order and repair as necessary before proceeding
further with this bulletin.
NOTE:
ONLY PERFORM THE FOLLOWING PROCEDURE SAFELY ON A HIGHWAY OR ROAD
OBEYING ALL POSTED SPEED LIMITS AND LAWS.
Attempt to duplicate the condition by switching on all accessory loads and driving the vehicle with
WOT accelerations through a shift sequence to see if the engine will reach the fuel shut off rev
limiter before the 2-3 or 1-2 shift is made.
If the bucking condition is experienced at approximately 5300 RPM before making the appropriate
upshifts, switch off all electrical loads and repeat the procedure. Repeat the procedure with the
electrical loads on and off a second time. If the bucking occurs with the electrical loads on and
does not occur with the loads off, perform the Repair Procedure.
PARTS REQUIRED:
1 56041403AA Sensor, Governor Pressure
REPAIR PROCEDURE:
This bulletin involves installing a newly designed governor pressure sensor.

DISCUSSION:
The factory fill power steering fluid for most 2004 model year Chrysler Group vehicles is ATF+4
(MS9602) and it provides superior performance at both low and high temperatures. WJ/WG and ZH
vehicles use unique power steering fluids. Refer to the table to identify factory fill and the approved
service power steering fluid by year and model. Note that MS9602 is Red in color and MS5931 and
MS9933 are Amber/Yellow in color. All three fluids will darken in color with usage and fluid color is
no longer an indication of fluid condition.
The part numbers for MS9602 are 05013457AA (quart) and 05013458AA (gallon). The part number
for MS5931 is 04883077 (quart). The part number for MB345 is 05127381AA.
MS9602 should not be mixed or used as a "topping off" fluid on systems requiring MS5931. On
some past models, MS9602 should be used as the replacement fluid. On these models, if a power
steering system is being serviced that results in a large fluid loss, such as a pump, hose or
gear/rack replacement, the complete system should be drained and filled with MS9602.

WARNING: The airbag system is a sensitive, complex electro-mechanical unit. Before attempting
to diagnose, remove or install the airbag system components you must first disconnect and isolate
the battery negative (ground) cable. Failure to do so could result in accidental deployment of the
airbag and possible personal injury. The fasteners, screws, and bolts, originally used for the airbag
components, have special coatings and are specifically designed for the airbag system. They must
never be replaced with any substitutes. Anytime a new fastener is needed, replace with the correct
fasteners provided in the service package or fasteners listed in the parts books
.

Steering Gear: Description and Operation
The power steering gear is a recirculating ball type gear. The gear acts as a rolling thread between
the worm shaft and rack piston. The worm shaft is supported by a thrust bearing at the lower end
and a bearing assembly at the upper end. When the worm shaft is turned the rack piston moves.

NOTE: Before performing this procedure, the worm bearing preload adjustment must be
preformed.
1. Rotate the stub shaft with a 12 point socket from stop to stop and count the number of turns.
2. Starting at either stop turn the stub shaft back 1/2 the total number of turns. This is the center of
the gear travel.
3. Place the torque wrench in the vertical position on the stub shaft. Rotate the wrench 45 degrees
each side of the center and record the highest
rotational torque in this range. This is the Over-Center Rotating Torque.
NOTE: The stub shaft must rotate smoothly without sticking or binding.
4. Rotate the stud shaft between 90° and 180° to the left of center and record the left off-center
preload. Repeat this to the right of center and record
the right off-center preload. The average of these two recorded readings is the Preload Rotating
Torque.
5. The Over-Center Rotating Torque should be 0.45 - 0.9 Nm (4 - 8 inch lbs.) higher than the
Preload Rotating Torque. 6. If an adjustment to the Over-Center Rotating Torque is necessary, first
loosen the adjuster lock nut. Then turn the pitman shaft adjuster screw back
(Counterclockwise) until fully extended, then turn back in (Clockwise) one full turn.
7. Remeasure Over-Center Rotating Torque. If necessary turn the adjuster screw and repeat
measurement until correct Over-Center Rotating Torque
is reached.
NOTE: To increase the preload turn the screw CLOCKWISE.

DATE: April 30, 1999
SUBJECT: "Buzz", "Whining", Or "Moaning" Like Noise From A Cold Transmission When Reverse
Is Selected.
OVERVIEW: This bulletin involves replacing the transmission regulator valve.
MODELS: 1996 - 1999
(AB) Ram Van
1996 - 1999 (AN) Dakota
1996 - 1999 (BR/BE) Ram Truck

1999 (WJ) Grand Cherokee
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC
TRANSMISSION.
SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission
when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning"
like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100
F.). The condition is caused by a resonance of the transmission regulator valve system.
Other items may cause regulator valve resonance, including air ingestion into the valve body or out
of specification parts. These two items may be the result a possible cracked pump housing, a torn
pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of
specification valve and/or valve body. You should remember these additional items / components
when you perform your diagnosis.
Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve
body or an entire automatic transmission was replaced with components manufactured after
August 1, 1995.
DIAGNOSIS:
Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual,
verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble
Codes (DTC's) are present, record them on the repair order and repair as necessary before
proceeding further with this bulletin.
For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to
determine if it applies to this vehicle before attempting to complete the analysis or repairs
described in this bulletin.
In most instances, the sump temperature of vehicles exhibiting transmission regulator valve
resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to
remain parked in a cool place overnight. Then perform the following steps:
1. Set the vehicle parking brake.
2. Start the engine (make certain windows are closed, to eliminate outside noise).
3. With brakes applied, place the transmission selector lever in reverse.
4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to
normal operating temperature (180 - 210 degrees F).
5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

Suspension Strut / Shock Absorber: Testing and Inspection
A knocking or rattling noise from a shock absorber may be caused by movement between
mounting bushings and metal brackets or attaching components. These noises can usually be
stopped by tightening the attaching nuts. If the noise persists, inspect for damaged and worn
bushings, and attaching components. Repair as necessary if any of these conditions exist.
A squeaking noise from the shock absorber may be caused by the hydraulic valving and may be
intermittent. This condition is not repairable and the shock absorber must be replaced.
The shock absorbers are not refillable or adjustable. If a malfunction occurs, the shock absorber
must be replaced. To test a shock absorber, hold it in an upright position and force the piston in
and out of the cylinder four or five times. The action throughout each stroke should be smooth and
even.
The spring eye and shock absorber bushings do not require any type of lubrication. Do not attempt
to stop bushing noise by lubricating them. Grease and mineral oil-base lubricants will deteriorate
the bushing.

OVERVIEW: This bulletin provides a diagnostic procedure for steering wander.
MODELS: 1998-2001 (AB) Ram Van/Wagon
SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight
steering corrections are necessary to be able to keep the vehicle moving in a straight line.
Steering wander can be created by a number of different conditions including but not limited to the
following:
^ Non-factory installed options.
^ Tires or wheels of different size.
^ Aftermarket wheels.
^ Tires that have a belt that has shifted.
^ Incorrect tire pressure.
^ A vehicle that is carrying extra added weight (e.g. tool boxes).
^ Steering and/or suspension components that are worn or damaged.
^ Wheel bearings that are loose, worn, or damaged.
^ A vehicle that is not within alignment specifications.
NOTE:
UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS,
CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER.
The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering
system components are functioning as designed and are not the root cause of steering wander.
DIAGNOSIS:
1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may
cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to
exceed the front or rear Gross Axle Weight Rating (GAWR).
2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged
and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to
wander and should be replaced before continuing with the diagnosis.
3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove
box).
NOTE:
TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN
PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB
OR LIGHT LOAD CONDITIONS.
4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road
crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70
mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the
vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a
steering wander condition.
NOTE:
VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD
TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION
MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED
ROADS, ETC.).

Description and Operation
Spare Tire: Description and Operation
The temporary spare tire is designed for emergency use only. The original tire should be repaired
and reinstalled at the first opportunity, or replaced with a new. Do not exceed speeds of 50 MPH
when the temporary spare tire is in use on the vehicle.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information >
Description and Operation
Wheels: Description and Operation
The rim size is on the safety certification label located on the drivers door shut face. The size of the
rim is determined by the drivetrain package. Original equipment wheels are designed for operation
up to the specified maximum vehicle capacity.
Fig. 1
All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised
sections between the rim flanges and rim drop well called safety humps.
Initial inflation of the tire forces the bead over these raised sections. In case of rapid loss of air
pressure, the raised sections help hold the tire on the wheel.
The wheel studs and nuts are designed for specific applications. All aluminum and some steel
wheels have wheel stud nuts with an enlarged nose. This enlarged nose is necessary to ensure
proper retention of the wheels. Do not use replacement studs or nuts with a different design or
lesser quality.

Wheels: Testing and Inspection
Inspect wheels for:
- Excessive run out
- Dents or cracks
- Damaged wheel lug nut holes
- Air leaks from any area or surface of the rim
NOTE: Do not attempt to repair a wheel by hammering, heating or welding.
If a wheel is damaged an original equipment replacement wheel should be used. When obtaining
replacement wheels, they should be equivalent in load carrying capacity. The diameter, width,
offset, pilot hole and bolt circle of the wheel should be the same as the original wheel.
WARNING: Failure to use equivalent replacement wheels may adversely affect the safety and
handling of the vehicle. Used wheels are not recommended. The service history of the wheel may
have included severe treatment or very high mileage. The rim could fail without warning.

DATE: September 22, 2000
SUBJECT: Steering Wander Diagnosis
OVERVIEW: This bulletin provides a diagnostic procedure for steering wander.
MODELS: 1998-2001 (AB) Ram Van/Wagon
SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight
steering corrections are necessary to be able to keep the vehicle moving in a straight line.
Steering wander can be created by a number of different conditions including but not limited to the
following:
^ Non-factory installed options.
^ Tires or wheels of different size.
^ Aftermarket wheels.
^ Tires that have a belt that has shifted.
^ Incorrect tire pressure.
^ A vehicle that is carrying extra added weight (e.g. tool boxes).
^ Steering and/or suspension components that are worn or damaged.
^ Wheel bearings that are loose, worn, or damaged.
^ A vehicle that is not within alignment specifications.
NOTE:
UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS,
CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER.
The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering
system components are functioning as designed and are not the root cause of steering wander.
DIAGNOSIS:
1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may
cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to
exceed the front or rear Gross Axle Weight Rating (GAWR).
2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged
and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to
wander and should be replaced before continuing with the diagnosis.
3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove
box).
NOTE:
TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN
PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB
OR LIGHT LOAD CONDITIONS.
4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road
crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70
mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the
vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a
steering wander condition.
NOTE:
VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD
TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION
MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED
ROADS, ETC.).
5. Raise the vehicle on an appropriate lift.

controls the positioning of the blend-air door in the heater-A/C housing. The blend- air door motor is
mounted to the top of the right end of the distribution duct under the instrument panel in the
passenger compartment.
A mechanical link is attached to the end of the blend-air door motor lever in the passenger
compartment and passes through a bellows-type boot and a small hole in the dash panel to the
engine compartment. In the engine compartment, the link is attached to the end of the blend air
door lever on the top cover of the heater-A/C housing.
The blend-air door motor is controlled by a potentiometer that is integral to the heater-only or
heater-A/C control. The rotary-type temperature control knob positions the potentiometer, and the
potentiometer controls the voltage to the blend-air door motor. The blend-air door motor moves the
blend-air door based upon the voltage level of the signal received from the potentiometer.
The blend-air door motor is accessible for service through the instrument panel glove box opening.
The blend-air door motor cannot be repaired and, if faulty or damaged, it must be replaced. The
mechanical link and boot are available for service replacement.

Blower Motor: Description and Operation
SYSTEM OPERATION
Front
The front blower motor and blower wheel are located in the blower housing in the engine
compartment. The blower housing is integral to the recirculation housing, which is secured to the
dash panel and the right cowl side inner panel below the heater-A/C housing. The blower motor
controls the velocity of air flowing through the heater-A/C system by spinning a squirrel cage-type
blower wheel within the housing at the selected speed. The blower motor and blower wheel can be
accessed for service from the engine compartment.
The front blower motor will only operate when the ignition switch is in the On position, and when
the heater-only or heater-A/C mode control switch knob is in any position, except Off. The blower
motor receives a fused battery feed through the blower motor relay whenever the ignition switch is
in the On position. The blower motor battery feed circuit is protected by a fuse in the Power
Distribution Center (PDC). The blower motor relay control circuit is protected by a fuse in the
junction block.
Blower speed is controlled by regulating the blower motor ground path through the heater-A/C
mode control switch, the front blower motor switch, the blower motor resistor, and the high speed
blower motor relay. When the blower motor switch is placed in the highest speed position it
energizes the high speed blower motor relay, which then provides a direct ground feed to the
blower motor and bypasses the remainder of the blower motor control circuit.
The blower motor and blower motor wheel cannot be repaired and, if faulty or damaged, they must
be replaced. The blower motor and blower wheel are each serviced separately.
Rear
The rear blower motor and blower wheel are located in the optional rear heater-A/C unit housing in
the passenger compartment. The rear heater-A/C unit is secured to the floor panel between the
fuel filler inlet housing and the left rear wheel house against the left side panel. The blower motor
controls the velocity of air flowing through the rear heater-A/C system by spinning a squirrel
cage-type blower wheel within the housing at the selected speed. The blower motor and blower
wheel can be accessed for service from the passenger compartment.
The rear blower motor will only operate when the ignition switch is in the On position. The blower
motor receives a fused battery feed through the blower motor relay whenever the ignition switch is
in the On position. The blower motor battery feed circuit is protected by a fuse in the Power

Blower speed is controlled by regulating the blower motor ground path through the blower motor
switch, the blower motor resistor, and the high speed blower motor relay. When the rear blower
motor switch is placed in the highest speed position it energizes the high speed blower motor relay,
which then provides a direct ground feed to the blower motor and bypasses the remainder of the
blower motor control circuit.
The rear blower motor and blower motor wheel cannot be repaired and, if faulty or damaged, they
must be replaced. The blower motor and blower wheel are each serviced separately.

the housing with two screws and is connected to the headlamp and dash wire harness. See Blower
Motor Resistor - Front in the Removal and Installation for more information.
The blower motor resistor has multiple resistor wires, each of which will change the resistance in
the blower motor ground path to change the blower motor speed. The blower motor switch directs
the ground path through the correct resistor wire to obtain the selected blower motor speed.
With the blower motor switch in the lowest speed position the ground path for the motor is applied
through all of the resistor wires. Each higher speed selected with the blower motor switch applies
the blower motor ground path through fewer of the resistor wires, increasing the blower motor
speed. When the blower motor switch is in the highest speed position, the blower motor resistor is
bypassed and the blower motor receives a direct path to ground through the high speed blower
motor relay.
The front blower motor resistor cannot be repaired and, if faulty or damaged, it must be replaced.

Compressor Clutch: Description and Operation
SYSTEM OPERATION
Compressor Clutch - Typical
The compressor clutch assembly consists of a stationary electromagnetic coil, a hub bearing and
pulley assembly, and a clutch plate. The electromagnetic coil unit and the hub bearing and pulley
assembly are each retained on the nose of the compressor front housing with snap rings. The
clutch plate is mounted on the compressor shaft and secured with a nut.
These components provide the means to engage and disengage the compressor from the engine
serpentine accessory drive belt. When the clutch coil is energized, it magnetically draws the clutch
into contact with the pulley and drives the compressor shaft. When the coil is not energized, the
pulley freewheels on the clutch hub bearing, which is part of the pulley. The compressor clutch and
coil are the only serviced parts on the compressor.
The compressor clutch is controlled by several components: the heater-A/C mode control switch,
the low pressure cut-off switch, the high pressure cut-off switch, the fin sensing cycling clutch
switch, the thermal limiter switch, the compressor clutch relay, and the Powertrain Control Module
(PCM). The PCM may delay compressor clutch engagement for up to thirty seconds.

Clutch/Pulley/Coil Remove/Install
11. Remove the snap ring that secures the clutch field coil assembly to the compressor front
housing.
12. Remove the clutch field coil assembly from the compressor front housing.
Inspection Examine the friction surfaces of the clutch pulley and the front plate for wear. The pulley
and front plate should be replaced if there is excessive wear or scoring.
If the friction surfaces are oily, inspect the shaft and nose area of the compressor for oil. If
excessive oil is present, the shaft seal is leaking and the compressor must be replaced.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch > Component
Information > Specifications > Page 5153
Check the clutch pulley bearing for roughness or excessive leakage of grease. Replace the
bearing, if required.
INSTALLATION 1. Position the back of the clutch field coil against the compressor front housing.
Be certain that the locating pin on the back of the coil lines up with
the indentation on the compressor front housing. This ensures the proper orientation of the coil and
the wire harness.
2. Install the clutch field coil snap ring (bevel side outward) with snap ring pliers. Be certain that the
snap ring is properly seated into the groove.
CAUTION: If the snap ring is not fully seated in the groove it will vibrate out, resulting in a clutch
failure and severe damage to the front housing of the compressor.
3. Install the clutch coil lead wire harness retaining clip on the compressor front housing and tighten
the retaining screw. 4. Plug in the compressor clutch wire harness connectors to the thermal limiter
switch. 5. Position the clutch pulley assembly onto the compressor.
CAUTION: Do not mar or contaminate the clutch pulley friction surface.
6. Install the clutch pulley assembly snap ring (bevel side outward) with snap ring pliers. Be certain
that the snap ring is properly seated in the
groove.
7. Place a trial stack of shims, 2.54 millimeters (0.10 inch) thick, on the compressor shaft.
Aligning Clutch Plate Splines
8. Note the machined mating splines on the compressor shaft and in the clutch plate hub. 9. Align
the mating splines and install the clutch plate on the compressor shaft.
10. Install the external front rotor snap ring with snap ring pliers. The bevel side of the snap ring
must be facing outward. Press the snap ring to make
sure it is properly seated in the groove.
Check Clutch Air Gap
11. With the front clutch plate assembly tight against the shims, measure the air gap between the
clutch plate and the pulley face with a feeler gauge.
The air gap should be from 0.35 to 0.65 millimeter (0.013 to 0.025 inch). If the proper air gap is not
obtained, add or subtract shims until the desired air gap is obtained.
12. Install the compressor shaft nut. Tighten the nut to 14.4 N.m (10.5 ft. lbs.).
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch > Component
Information > Specifications > Page 5154
13. The shims may compress after tightening the compressor shaft nut. Check the air gap in four or
more places to verify that the air gap is still
correct. Spin the pulley for a final check.
14. Reverse the remaining removal procedures to complete the installation.
Clutch Break-In After a new compressor clutch has been installed, cycle the compressor clutch
approximately twenty times (five seconds on, then five seconds off). During this procedure, set the
heater-A/C control to the recirculation mode (Max-A/C), the blower motor switch in the highest
speed position, and the engine speed at 1500 to 2000 rpm. This procedure (burnishing) will seat
the opposing friction surfaces and provide a higher compressor clutch torque capability

Information > Testing and Inspection
Compressor Clutch Coil: Testing and Inspection
The battery must be fully-charged before performing the following tests. Refer to Starting and
Charging/Battery for more information.
1. Connect an ammeter (0 to 10 ampere scale) in series with the clutch coil terminal. Use a
voltmeter (0 to 20 volt scale) with clip-type leads for
measuring the voltage across the battery and the compressor clutch coil.
2. With the heater-A/C mode control switch in any A/C mode, and the blower motor switch in the
lowest speed position, start the engine and run it at
normal idle.
3. The compressor clutch coil voltage should read within two volts of the battery voltage. If there is
voltage at the clutch coil, but the reading is not
within Two Volts of the battery voltage, test the clutch coil feed circuit for excessive voltage drop
and repair as required. If there is no voltage reading at the clutch coil, use a DRB scan tool and the
proper Diagnostic Procedures for testing of the compressor clutch circuit. The following
components must be checked and repaired as required before you can complete testing of the
clutch coil: Fuses in the junction block and the Power Distribution Center
- Heater-A/C mode control switch
- Compressor clutch relay
- Fin sensing cycling clutch switch
- High pressure cut-off switch
- Low pressure cut-off switch
- Thermal limiter switch
- Powertrain Control Module.
4. The compressor clutch coil is acceptable if the current draw measured at the clutch coil is 2.0 to
3.9 amperes with the electrical system voltage at
11.5 to 12.5 volts. This should only be checked with the work area temperature at 210 C (700 F). If
system voltage is more than 12.5 volts, add electrical loads by turning on electrical accessories
until the system voltage drops below 12.5 volts. a. If the clutch coil current reading is four amperes
or more, the coil is shorted and should be replaced. b. If the clutch coil current reading is zero, the
coil is open and should be replaced.

Compressor Clutch Relay: Description and Operation
SYSTEM OPERATION
The compressor clutch relay is a International Standards Organization (ISO) micro-relay The
terminal designations and functions are the same as a conventional ISO relay. However, the
micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay
case dimensions are smaller than those of the conventional ISO relay
The compressor clutch relay is a electromechanical device that switches battery current to the
compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the
relay. The PCM responds to inputs from the heater-A/C mode control switch, the low pressure
cut-off switch, the high pressure cut-off switch, and the fin sensing cycling clutch switch. See
Compressor Clutch Relay in the Diagnosis and Testing for more information.
The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine
compartment. Refer to the PDC label for relay identification and location.
The compressor clutch relay cannot be repaired and, if faulty or damaged, it must be replaced.

Condenser HVAC: Description and Operation
SYSTEM OPERATION
The condenser is located in the air flow in front of the engine cooling radiator. The condenser is a
heat exchanger that allows the high-pressure refrigerant gas being discharged by the compressor
to give up its heat to the air passing over the condenser fins. When the refrigerant gas gives up its
heat, it condenses. When the refrigerant leaves the condenser, it has become a high-pressure
liquid refrigerant.
The volume of air flowing over the condenser fins is critical to the proper cooling performance of
the air conditioning system. Therefore, it is important that there are no objects placed in front of the
radiator grille openings in the front of the vehicle or foreign material on the condenser fins that
might obstruct proper air flow. Also, any factory-installed air seals or shrouds must be properly
reinstalled following radiator or condenser service.
The condenser cannot be repaired and, if faulty or damaged, it must be replaced.

Some vehicle operators may experience a musty odor from the A/C system, primarily at start up in
hot and humid climates. This odor may be the result of microbial growth on the cooling coil. During
normal A/C system operation, condensation forms in and around the NC cooling coil. When
airborne pollutants mix with this condensation, bacteria and fungi growth begins and odor results.
DIAGNOSIS:
If the operator describes, or the technician experiences a musty odor when operating the A/C
system, perform the appropriate Repair Procedure based on the vehicle model.
PARTS REQUIRED:
A/C COOLING COIL CLEANER REQUIREMENTS BY VEHICLE MODEL

Hot/Humid > Page 5202
Some vehicle operators may experience a musty odor from the A/C system, primarily at start up in
hot and humid climates. This odor may be the result of microbial growth on the cooling coil. During
normal A/C system operation, condensation forms in and around the NC cooling coil. When
airborne pollutants mix with this condensation, bacteria and fungi growth begins and odor results.
DIAGNOSIS:
If the operator describes, or the technician experiences a musty odor when operating the A/C
system, perform the appropriate Repair Procedure based on the vehicle model.

Evaporator Core: Description and Operation Combination Coil
SYSTEM OPERATION
Models equipped with the optional rear heater-A/C unit have a combination coil located within the
rear unit housing. It is called a combination coil because it combines the functions of a heater core
and an evaporator coil into a single heat exchanger unit.
The combination coil features six rows of tube and fin construction. The two rows located toward
the outboard side of the vehicle serve as the heater core and have engine coolant circulated
through them whenever the rear water valve is open. The four rows toward the inboard side of the
vehicle serve as the evaporator and have refrigerant circulated through them whenever the air
conditioning compressor is operating. The amount of refrigerant flowing through the combination
coil is controlled by a dedicated rear thermal expansion valve.
The combination coil can be accessed for service by removing the rear heater-A/C unit upper
housing. The combination coil cannot be repaired and, if faulty or damaged, it must be replaced.

Evaporator Core: Description and Operation Evaporator Coil
SYSTEM OPERATION
Front
The evaporator coil is located in the heater-A/C housing, on the right side of the engine
compartment. The evaporator coil is positioned in the heater-A/C housing so that all air that enters
the housing must pass over the fins of the evaporator before it is distributed through the system
ducts and outlets. However, air passing over the evaporator coil fins will only be conditioned when
the compressor is engaged and circulating refrigerant through the evaporator coil tubes.
Refrigerant enters the evaporator from the expansion valve as a low-temperature, low-pressure
mixture of liquid and gas. As air flows over the fins of the evaporator, the humidity in the air
condenses on the fins, and the heat from the air is absorbed by the refrigerant. Heat absorption
causes the refrigerant to boil and vaporize. The refrigerant becomes a hightemperature,
low-pressure gas before it leaves the evaporator.
The evaporator coil cannot be repaired and, if faulty or damaged, it must be replaced.
Rear
Models equipped with the optional rear heater-A/C unit have a combination coil located within the
rear unit housing. The combination coil functions as both the rear heater core and the rear
evaporator coil. See Combination Coil in the Description and Operation for more information.

Expansion Valve: Description and Operation
SYSTEM OPERATION
Front
The front "H" valve-type thermal expansion valve (TXV) is located at the front of the heater-A/C
housing between the liquid and suction lines and the evaporator coil. High-pressure, high
temperature liquid refrigerant from the liquid line passes through the expansion valve orifice,
converting it into a low- pressure, low-temperature mixture of liquid and gas before it enters the
evaporator coil.
A temperature sensor in the expansion valve control head monitors the temperature of the
refrigerant leaving the evaporator coil through the suction line and adjusts the orifice size at the
liquid line to let the proper amount of refrigerant into the evaporator coil to meet the vehicle cooling
requirements. Controlling the refrigerant flow through the evaporator ensures that none of the
refrigerant leaving the evaporator is still in a liquid state, which could damage the compressor.
The expansion valve is a factory calibrated unit and cannot be adjusted or repaired. If faulty or
damaged, the expansion valve must be replaced.
Rear
Models equipped with the optional rear heater-A/C unit have a second "H" valve-type thermal
expansion valve (TXV) installed between the rear unit liquid and suction lines, and the combination
coil. High pressure, high temperature liquid refrigerant from the liquid line passes through the
expansion valve orifice, converting it into a low-pressure, low-temperature mixture of liquid and gas
before it enters the combination coil.
A temperature sensor in the expansion valve control head monitors the temperature of the
refrigerant leaving the combination coil through the suction line, and adjusts the orifice size at the
liquid line to let the proper amount of refrigerant into the combination coil to meet the vehicle
cooling requirements. Controlling the refrigerant flow through the combination coil ensures that
none of the refrigerant leaving the combination coil is still in a liquid state, which could damage the

Expansion Valve: Testing and Inspection
These tests must be made at an ambient temperature of 21 to 290 C (70 to 850 F).
Front (ONLY) 1. Attach a manifold gauge set. Close the vehicle doors and windows, start the
engine, and hold the engine speed at 1,000 rpm. Set the heater-A/C
mode control switch knob in the recirculation mode (Max A/C) position, the temperature control
knob in the full hot position, and the blower motor switch in the highest speed position. Disconnect
and plug the vacuum harness connector at the water valve in the engine compartment. Unplug the
fin sensing cycling clutch switch wire harness connector.
2. Operate the air conditioning system for at least five minutes to stabilize the system, and to
provide sufficient reheat to load the evaporator. The
discharge pressure (high side) at the service port should reach 966 to 1656 kPa (140 to 240 psi). If
this discharge pressure cannot be obtained, check the refrigerant system charge. See Refrigerant
System Charge in the Service Procedures.
WARNING: EXTREME CARE MUST BE USED WHEN HANDLING LIQUID CARBON DIOXIDE
(CO2), AS SKIN INJURY CAN OCCUR. PROTECTIVE GLOVES SHOULD BE WORN.
3. Apply liquid carbon dioxide (CO2) to the expansion valve control head (completely cover the
head) for a minimum of thirty seconds. Observe the
manifold gauge set. The suction pressure (low side) must drop to below 50 kPa (7.25 psi). If this
reading is not obtained, the expansion valve is faulty and must be replaced.
4. Remove the liquid carbon dioxide (CO2) from the control head. Observe the manifold gauge set.
The suction pressure (low side) must increase to
a minimum of 262 kPa (38 psi), and then stabilize to a pressure of 172 to 240 kPa (25 to 35 psi). If
these readings are not obtained, the expansion valve is faulty and must be replaced.
5. Set the engine idle speed at 1,000 rpm and the blower motor switch in the highest speed
position. The suction pressure (low side) should be 138 to
207 kPa (20 to 30 psi). If the discharge pressure (highside) is higher than 1656 kPa (240 psi),
check for a restricted discharge line. Also check the engine cooling system for overheating, air
trapped in the system, or a faulty fan drive. If the discharge pressure (high side) is less than 966
kPa (140 psi), deck for a faulty compressor.
Front And Rear AC 1. Attach a manifold gauge set. Close the vehicle doors and windows, start the
engine, and hold the engine speed at 1,000 rpm. Set the heater-A/C
mode control switch knob in the recirculation mode (Max A/C) position, the temperature control
knob in the full hot position, and both the front and rear blower motor switches in their highest
speed positions. Disconnect and plug the vacuum harness connector at the water valve in the
engine compartment. Unplug the fin sensing cycling clutch switch wire harness connector.
2. Operate the air conditioning system for at least five minutes to stabilize the system, and to
provide sufficient reheat to load the front evaporator
and the rear combination coil. The discharge pressure (high side) at the service port should reach
966 to 1656 kPa (140 to 240 psi). If this discharge pressure cannot be obtained, check the
refrigerant system charge. See Refrigerant System Charge.
WARNING: EXTREME CARE MUST BE USED WHEN HANDLING LIQUID CARBON DIOXIDE
(CO2) AS SKIN INJURY CAN OCCUR. PROTECTIVE GLOVES SHOULD BE WORN.
3. Both the front and rear expansion valves should be checked for correct operation. Apply liquid
carbon dioxide (CO2) to the front expansion valve
control head (completely cover the head) for a minimum of thirty seconds. Remove the rear
heater-A/C trim cover and apply liquid carbon dioxide (CO2) to the rear expansion valve control
head (completely cover the head) for a minimum of thirty seconds. Grasp the suction line (large
line) off the combination coil with a bare hand and hold it for at least two minutes. Use the same
procedure with the front expansion valve. Grasp the suction line jumper below the expansion valve
(before the rear suction line tee) with a bare hand and hold for at least two minutes. When testing
the front expansion valve, place the rear blower motor switch in the Off position.
4. With a correctly operating expansion valve, the suction line will feel warm with the closing of the
valve (cold applied). Then the line will cool
sharply within two minutes as the valve opens. If this temperature change does not occur, the
expansion valve is faulty and must be replaced.

SYSTEM OPERATION
Front
The heater core is located in the heater-A/C housing, on the right side of the engine compartment.
It is a heat exchanger made of rows of tubes and fins. Engine coolant is circulated through heater
hoses to the heater core whenever the front water valve is open. As the coolant flows through the
heater core, heat removed from the engine is transferred to the heater core fins and tubes.
Air directed through the heater core picks up the heat from the heater core fins. The blend air door
allows control of the heater output air temperature by controlling how much of the air flowing
through the heater-A/C housing is directed through or around the heater core. The blower motor
speed controls the volume of air flowing through the heater-A/C system.
The heater core cannot be repaired and, if faulty or damaged, it must be replaced.

High Pressure Safety Valve HVAC: Description and Operation
SYSTEM OPERATION
High Pressure Relief Valve
The high pressure relief valve is located on the rear surface of the compressor housing. This
mechanical valve is designed to vent refrigerant from the system to protect against damage to the
compressor and other system components, caused by condenser air flow restriction or an
overcharge of refrigerant.
The high pressure relief valve vents the system when a discharge pressure of 3445 to 4135 kPa
(500 to 600 psi) or above is reached. The valve closes with a minimum discharge pressure of 2756
kPa (400 psi) is reached.
The high pressure relief valve vents only enough refrigerant to reduce the system pressure, and
then re-seats itself. The majority of the refrigerant is conserved in the system. If the valve vents
refrigerant, it does not mean the valve is faulty.
On new compressor assemblies, a mylar disc is applied to the venting port of the valve. The disc is
primarily intended for protection of the valve during the painting operation. A missing or damaged
disc does not indicate failure. If the mylar disc has loosened or come off, apply a drop or two of
refrigerant oil into the valve mechanism through the venting holes. This will prevent salt, dirt, or
moisture from affecting the operation of the valve.
The high pressure relief valve is only serviced as part of the compressor assembly, and must not
be removed or otherwise disturbed.

Hose/Line HVAC: Description and Operation
SYSTEM OPERATION
Refrigerant Line The refrigerant lines and hoses are used to carry the refrigerant between the
various air conditioning system components. A barrier hose design with a nylon tube inner hose
liner is used for the R-134a air conditioning system on this vehicle. This nylon liner helps to further
contain the R-134a refrigerant, which has a smaller molecular structure than R-12 refrigerant. The
ends of the refrigerant hoses are made from lightweight aluminum, and use brazeless fittings.
Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air
conditioning system. Kinks and sharp bends reduce the flow of refrigerant in the system. A good
rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the
diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at
least 80 millimeters (3 inches) from the exhaust manifold.
High pressures are produced in the refrigerant system when the air conditioning compressor is
operating. Extreme care must be exercised to make sure that each of the refrigerant system
connections is pressure-tight and leak free. It is a good practice to inspect all flexible hose
refrigerant lines at least once a year to make sure they are in good condition and properly routed.
The refrigerant lines and hoses cannot be repaired and, if faulty or damaged, they must be
replaced.

SYSTEM OPERATION
A single filter-drier unit is used for both the front-only A/C system, and for the combined front and
rear A/C system. The filter-drier is mounted on the right side of the engine compartment in front of
the heater-A/C housing. It is located in the liquid line between the condenser outlet and the
evaporator inlet. Refrigerant enters the filter-drier as a high- pressure, high-temperature liquid.
The filter-drier performs a filtering action to prevent foreign material in the refrigerant from
contaminating the expansion valve. A desiccant bag is mounted inside the filter-drier canister to
absorb any moisture which may have entered and become trapped within the refrigerant system. In
addition, during periods of high demand air conditioner operation, the filter-drier acts as a reservoir
to store surplus liquid refrigerant.
The filter-drier cannot be repaired. If the filter-drier is faulty or damaged, if the refrigerant system
has been contaminated, or if the system has been left open to the atmosphere for an
indeterminable period, it must be replaced.

Refrigerant: Description and Operation
SYSTEM OPERATION
The refrigerant used in this air conditioning system is a HydroFluoroCarbon (HFC), type R-134a.
Unlike R-12, which is a ChloroFluoroCarbon (CFC), R-134a refrigerant does not contain
ozone-depleting chlorine. R-134a refrigerant is a non-toxic, non-flammable, clear, and colorless
liquefied gas.
Even though R-134a does not contain chlorine, it must be reclaimed and recycled just like
CFC-type refrigerants. This is because R-134a is a greenhouse gas and can contribute to global
warming.
R-134a refrigerant is not compatible with R-12 refrigerant in an air conditioning system. Even a
small amount of R-12 added to an R-134a refrigerant system will cause compressor failure,
refrigerant oil sludge or poor air conditioning system performance. In addition, the PolyAlkylene
Glycol (PAG) synthetic refrigerant oils used in an R-134a refrigerant system are not compatible
with the mineral-based refrigerant oils used in an R-12 refrigerant system.
R-134a refrigerant system service ports, service tool couplers and refrigerant dispensing bottles
have all been designed with unique fittings to ensure that an R-134a system is not accidentally
contaminated with the wrong refrigerant (R-12). There are also labels posted in the engine
compartment of the vehicle and on the compressor identifying to service technicians that the air
conditioning system is equipped with R-134a.

Refrigerant Oil: Service and Repair
Refrigerant Oil Level
Refrigerant Oil Capacities
When an air conditioning system is assembled at the factory, all components except the
compressor and the combination coil, if the vehicle is so equipped, are refrigerant oil free. After the
refrigerant system has been charged and operated, the refrigerant oil in the compressor and the
combination coil is dispersed throughout the refrigerant system. The combination coil, evaporator,
filter-drier, condenser, and compressor will each retain a significant amount of the needed
refrigerant oil.
It is important to have the correct amount of oil in the refrigerant system. This ensures proper
lubrication of the compressor. Too little oil will result in damage to the compressor. Too much oil
will reduce the cooling capacity of the air conditioning system.
It will not be necessary to check the oil level in the compressor or to add oil, unless there has been
an oil loss. An oil loss may occur due to a rupture or leak from a refrigerant line, a connector fitting,
a component, or a component seal. If a leak occurs, add 30 milliliters (1 fluid ounce) of refrigerant
oil to the refrigerant system after the repair has been made. Refrigerant oil loss will be evident at
the leak point by the presence of a wet, shiny surface around the leak.
Refrigerant oil must be added when a filter-drier, evaporator coil, combination coil, or condenser
are replaced. See the Refrigerant Oil Capacities chart. When a compressor is replaced, the
refrigerant oil must be drained from the old compressor and measured. Drain all of the refrigerant
oil from the new compressor, then fill the new compressor with the same amount of refrigerant oil
that was drained out of the old compressor.

High Pressure Sensor / Switch: Description and Operation
SYSTEM OPERATION
High Pressure Cut-Off Switch The high pressure cut-off switch is located on the discharge line near
the condenser. The switch is screwed onto a fitting that contains a Schrader-type valve, which
allows the switch to be serviced without discharging the refrigerant system. The discharge line
fitting is equipped with an 0-ring to seal the switch connection.
The high pressure cut-off switch is connected in series electrically with the low pressure cut-off
switch between the fin sensing cycling clutch switch and the Powertrain Control Module (PCM).
The switch contacts open and close causing the PCM to turn the compressor clutch on and off.
This prevents compressor operation when the discharge line pressure approaches high levels.
The high pressure cut-off switch contacts are open when the discharge line pressure rises above
about 3100 to 3375 kPa (450 to 490 psi). The switch contacts will close when the discharge line
pressure drops to about 1860 to 2275 kPa (270 to 330 psi).
The high pressure cut-off switch is a factory-calibrated unit. The switch cannot be adjusted or
repaired and, if faulty or damaged, it must be replaced.

SYSTEM OPERATION
Fin Sensing Cycling Clutch Switch
Fin Sensing Cycling Clutch Switch The fin sensing cycling clutch switch is used on this model to
signal the Powertrain Control Module (PCM) to cycle the compressor clutch on arid off in order to
control the evaporator temperature. Controlling the evaporator temperature prevents condensate
water on the evaporator fins from freezing and obstructing air conditioning system air flow.
The fin sensing cycling clutch switch consists of a probe and a switch unit. The probe, which is a
Negative Temperature Coefficient (NTC) thermistor in a capillary tube, is inserted between the front
evaporator coil fins to monitor evaporator temperature. The switch unit contains internal control
logic that monitors the input from the probe in order to switch an internal transistor that controls the
output to the PCM. when the fin sensing cycling clutch switch sees a temperature input below
about 1.60 °C (350 °F), it signals the PCM to cycle the compressor off. When the temperature input
reaches above about 3.90 °C (390 °F), the switch signals the PCM to cycle the compressor back
on.
The fin sensing cycling clutch switch can be accessed for service by removing the screws and
carefully lifting the front of the top cover up from the heater-A/C housing. The fin sensing cycling
clutch switch is a sealed unit and cannot be adjusted or repaired. If faulty or damaged, the switch
must be replaced.

Low Pressure Sensor / Switch: Testing and Inspection Fin Sensing Cycling Clutch Switch
Before testing the fin sensing cycling clutch switch, verity that the refrigerant system has the correct
refrigerant charge. Also check that both the low and high pressure cut-off switches are functional,
and confirm that the compressor clutch is operational. Use a volt/ohmmeter to test the switch.
1. Turn the ignition switch in the On position. Place the heater-A/C mode control switch in any A/C
position. Check for battery voltage at the fused
ignition switch output (run/start) circuit cavity of the fill sensing cycling clutch switch wire harness
connector. If OK, go to Step 3. If not OK, repair the open circuit to the fuse in the junction block as
required.
2. With the ambient temperature between 20 to 30° C (68 to 900 F), start the engine and run the air
conditioning system. The compressor clutch
should cycle on and off two to three times per minute. If the clutch fails to cycle at this rate in these
temperatures, replace the faulty fin sensing cycling clutch switch.
NOTE: If the ambient temperature is above 32° C (90° F) the compressor clutch may stay engaged
and not cycle due to the high heat load. This condition is normal.

Low Pressure Sensor / Switch: Testing and Inspection Low Pressure Cut-Off Switch
Before performing diagnosis of the low pressure cut-off switch, remember that lower ambient
temperatures, below about -1° C (30° F), during cold weather will open the switch contacts and
prevent compressor operation due to the pressure/temperature relationship of the refrigerant.
Also verify that the refrigerant system has the correct refrigerant charge. See Refrigerant System
Charge in the Service Procedures.
1. Disconnect and isolate the battery negative cable. 2. Unplug the low pressure cut-off switch wire
harness connector from the switch on the suction line jumper fitting. 3. Install a jumper wire
between the two cavities of the low pressure cut-off switch wire harness connector. 4. Connect a
manifold gauge set to the refrigerant system service ports. See Refrigerant System Service
Equipment and Refrigerant System Service
Ports.
5. Connect the battery negative cable. 6. Place the heater-A/C mode control switch knob in any
A/C position and start the engine. 7. Check for continuity between the two terminals of the low
pressure cut-off switch. There should be continuity with a suction pressure (low side)
reading of 103 to 172 kPa (15 to 25 psi) or above, arid no continuity with a suction pressure
reading of 48 to 90 kPa (7 to 13 psi) or below. If OK, test and repair the A/C switch sense circuit as
required. If not OK, replace the faulty switch.

Blower Motor Relay: Description and Operation Blower Motor Relay
SYSTEM OPERATION
Front
The front blower motor relay is a International Standards Organization (ISO)-type relay. The relay
is a electromechanical device that switches battery current from a fuse in the Power Distribution
Center (PDC) directly to the blower motor. The relay is energized when the relay coil is provided a
voltage signal by the ignition switch. This arrangement reduces the amount of battery current that
must flow through the ignition switch.
The blower motor relay control circuit is protected by a fuse located in the junction block. When the
relay is de-energized, the blower motor receives no battery current. See Blower Motor Relay in the
Diagnosis and Testing for more information.
The front blower motor relay is located in the PDC in the engine compartment. Refer to the PDC
label for blower motor relay identification and location.
The blower motor relay cannot be repaired and, if faulty or damaged, it must be replaced.
Rear
The blower motor relay for the optional rear heater-A/C unit is a International Standards

Compressor Clutch Relay: Description and Operation
SYSTEM OPERATION
The compressor clutch relay is a International Standards Organization (ISO) micro-relay The
terminal designations and functions are the same as a conventional ISO relay. However, the
micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay
case dimensions are smaller than those of the conventional ISO relay
The compressor clutch relay is a electromechanical device that switches battery current to the
compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the
relay. The PCM responds to inputs from the heater-A/C mode control switch, the low pressure
cut-off switch, the high pressure cut-off switch, and the fin sensing cycling clutch switch. See
Compressor Clutch Relay in the Diagnosis and Testing for more information.
The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine

High Pressure Sensor / Switch: Description and Operation
SYSTEM OPERATION
High Pressure Cut-Off Switch The high pressure cut-off switch is located on the discharge line near
the condenser. The switch is screwed onto a fitting that contains a Schrader-type valve, which
allows the switch to be serviced without discharging the refrigerant system. The discharge line
fitting is equipped with an 0-ring to seal the switch connection.
The high pressure cut-off switch is connected in series electrically with the low pressure cut-off
switch between the fin sensing cycling clutch switch and the Powertrain Control Module (PCM).
The switch contacts open and close causing the PCM to turn the compressor clutch on and off.
This prevents compressor operation when the discharge line pressure approaches high levels.
The high pressure cut-off switch contacts are open when the discharge line pressure rises above
about 3100 to 3375 kPa (450 to 490 psi). The switch contacts will close when the discharge line
pressure drops to about 1860 to 2275 kPa (270 to 330 psi).
The high pressure cut-off switch is a factory-calibrated unit. The switch cannot be adjusted or
repaired and, if faulty or damaged, it must be replaced.

SYSTEM OPERATION
Fin Sensing Cycling Clutch Switch
Fin Sensing Cycling Clutch Switch The fin sensing cycling clutch switch is used on this model to
signal the Powertrain Control Module (PCM) to cycle the compressor clutch on arid off in order to
control the evaporator temperature. Controlling the evaporator temperature prevents condensate
water on the evaporator fins from freezing and obstructing air conditioning system air flow.
The fin sensing cycling clutch switch consists of a probe and a switch unit. The probe, which is a
Negative Temperature Coefficient (NTC) thermistor in a capillary tube, is inserted between the front
evaporator coil fins to monitor evaporator temperature. The switch unit contains internal control
logic that monitors the input from the probe in order to switch an internal transistor that controls the
output to the PCM. when the fin sensing cycling clutch switch sees a temperature input below
about 1.60 °C (350 °F), it signals the PCM to cycle the compressor off. When the temperature input
reaches above about 3.90 °C (390 °F), the switch signals the PCM to cycle the compressor back
on.
The fin sensing cycling clutch switch can be accessed for service by removing the screws and
carefully lifting the front of the top cover up from the heater-A/C housing. The fin sensing cycling
clutch switch is a sealed unit and cannot be adjusted or repaired. If faulty or damaged, the switch
must be replaced.

Low Pressure Sensor / Switch: Testing and Inspection Fin Sensing Cycling Clutch Switch
Before testing the fin sensing cycling clutch switch, verity that the refrigerant system has the correct
refrigerant charge. Also check that both the low and high pressure cut-off switches are functional,
and confirm that the compressor clutch is operational. Use a volt/ohmmeter to test the switch.
1. Turn the ignition switch in the On position. Place the heater-A/C mode control switch in any A/C
position. Check for battery voltage at the fused
ignition switch output (run/start) circuit cavity of the fill sensing cycling clutch switch wire harness
connector. If OK, go to Step 3. If not OK, repair the open circuit to the fuse in the junction block as
required.
2. With the ambient temperature between 20 to 30° C (68 to 900 F), start the engine and run the air
conditioning system. The compressor clutch
should cycle on and off two to three times per minute. If the clutch fails to cycle at this rate in these

Low Pressure Sensor / Switch: Testing and Inspection Low Pressure Cut-Off Switch
Before performing diagnosis of the low pressure cut-off switch, remember that lower ambient
temperatures, below about -1° C (30° F), during cold weather will open the switch contacts and
prevent compressor operation due to the pressure/temperature relationship of the refrigerant.
Also verify that the refrigerant system has the correct refrigerant charge. See Refrigerant System
Charge in the Service Procedures.
1. Disconnect and isolate the battery negative cable. 2. Unplug the low pressure cut-off switch wire
harness connector from the switch on the suction line jumper fitting. 3. Install a jumper wire
between the two cavities of the low pressure cut-off switch wire harness connector. 4. Connect a
manifold gauge set to the refrigerant system service ports. See Refrigerant System Service
Equipment and Refrigerant System Service
Ports.
5. Connect the battery negative cable. 6. Place the heater-A/C mode control switch knob in any
A/C position and start the engine. 7. Check for continuity between the two terminals of the low
pressure cut-off switch. There should be continuity with a suction pressure (low side)
reading of 103 to 172 kPa (15 to 25 psi) or above, arid no continuity with a suction pressure
reading of 48 to 90 kPa (7 to 13 psi) or below. If OK, test and repair the A/C switch sense circuit as

Description and Operation
Vacuum Check Valve HVAC: Description and Operation
SYSTEM OPERATION
A vacuum check valve is installed in the vacuum supply line in the vacuum harness. The check
valve
is located near the left end of the distribution duct under the instrument panel in the passenger
compartment. The vacuum check valve is designed to allow vacuum to flow in only one direction
through the vacuum supply circuits.
The use of a vacuum check valve helps to maintain the system vacuum needed to retain the
selected heater-A/C mode settings. The check valve will prevent the engine from bleeding down
system vacuum through the intake manifold during extended heavy engine load (low engine
vacuum) operation.
The vacuum check valve cannot be repaired and, if faulty or damaged, it must be replaced.

Vacuum Check Valve HVAC: Testing and Inspection
Adjust Vacuum Test Bleed Valve
Vacuum control is used to operate the mode doors in the heater-only and the heater-A/C systems.
Testing of the heater-A/C mode control switch operation will determine if the vacuum and electrical
controls are functioning. However, it is possible that a vacuum control system that operates
perfectly at engine idle (high engine vacuum) may not function properly at high engine speeds or
loads (low engine vacuum). This can be caused by leaks in the vacuum system, or by a faulty or
improperly installed vacuum check valve.
A vacuum system test will help to identify the source of poor vacuum system performance or
vacuum system leaks. Before starting this test, stop the engine and make certain that the problem
is not a disconnected vacuum supply tube at the engine vacuum source or at the vacuum reservoir.
Use an adjustable vacuum test set (Special Tool C-3707) and a suitable vacuum pump to test the
heater-A/C vacuum control system. With a finger placed over the end of the vacuum test hose
probe, adjust the bleed valve on the test set gauge to obtain a vacuum of exactly 27 kPa (8 in.
Hg.). Release and block the end of the probe several times to verify that the vacuum reading
returns to the exact 27 kPa (8 in. Hg.) setting. Otherwise, a false reading will be obtained during
testing.
Vacuum Check Valve 1. Remove the vacuum check valve. The valve is located in the vacuum
supply tube (black) within the vacuum harness on the left end of the
distribution duct under the instrument panel in the passenger compartment. The vacuum check
valve must be removed in order to perform the following tests. See Vacuum Check Valve in the
Removal and Installation procedures.
2. Connect the test set vacuum supply hose to the heater-A/C control side of the valve. When
connected to this side of the check valve, no vacuum
should pass and the test set gauge should return to the 27 kPa (8 in. Hg.) setting. If OK, go to step
Step 4. If not OK, replace the faulty valve.
3. Connect the test set vacuum supply hose to the engine vacuum side of the valve. When
connected to this side of the check valve, vacuum should
flow through the valve without restriction. If not OK, replace the faulty valve.
Heater-A/C Controls 1. Connect the test set vacuum probe to the heater-A/C vacuum supply
(black) tube in the engine compartment. Position the test set gauge so that it
can be viewed from the passenger compartment.
2. Place the heater-A/C mode control switch knob in each mode position, one position at a time,
and pause after each selection. The test set gauge
should return to the 27 kPa (8 in. Hg.) setting shortly after each selection is made. If not OK, a
component or vacuum line in the vacuum circuit of the selected mode has a leak. See Locating
Vacuum Leaks.
CAUTION: Do not use lubricant on the switch ports or in the holes in the plug, as lubricant will ruin
the vacuum valve in the switch. A drop of clean water in the connector plug holes will help the
connector slide onto the switch ports.

DISCUSSION:
Airbag
When servicing any airbag system, it is essential to follow the proper Service Manual and/or
Diagnostic Manual procedures for diagnosing, testing, and replacing of any component. When
diagnosing any airbag squib circuit Diagnostic Trouble Code (DTC) with a DRBIII(R), the use of the
Airbag Load Tool (Special Tool 8310 and 8443) is required. The Airbag Load Tool, used in
conjunction with the DRBIII(R) are used to isolate and test components and wiring for failure. Only
replace the component or wiring that has failed. This will reduce unnecessary cost to the customer
or DaimlerChrysler.
NOTE:
AIRBAG REPLACEMENT IS NOT REQUIRED EVERY TIME IT IS REMOVED OR WHEN
ANOTHER COMPONENT HAS FAILED. USE OF THE DRBIII(R) AND AIRBAG LOAD TOOL
WILL DETERMINE IF THE AIRBAG HAS FAILED AND REPLACEMENT IS NEEDED.

Clock Springs
Recent analysis of returned clock springs have indicated that prior service may have contributed to
the clock spring's failure.
^ Do not use silicone or any other lubricant spray on or near the clock spring. Lubricants are often
used in the clock spring area of the steering column to eliminate noise. Lubricants may have an
adverse effect on the clock spring.
^ Clock spring centering. Any repair that may disrupt the positioning of the steering wheel with the
front wheels will require that the clock spring be centered. This includes clock spring replacement,
steering column service, HVAC service, steering gear service, and front suspension crossmember
service. Refer to the appropriate Service Manual for the clock spring centering procedure.

SYSTEM OPERATION
Airbag Module
Driver Side The airbag module protective trim cover is the most visible part of the driver side airbag
system. The module is mounted directly to the steering wheel. Located under the airbag module
trim cover are the horn switch, the airbag cushion, and the air-bag cushion supporting components.
The airbag module includes a housing to which the cushion and inflator are attached and sealed.
The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged.
The inflator assembly is mounted to the back of the airbag module. The inflator seals the hole in
the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied
with the proper electrical signal. The protective trim cover is fitted to the front of the airbag module
and forms a decorative cover in the center of the steering wheel. Upon airbag deployment, this
cover will split at a predetermined breakout line.
Passenger Side The airbag door on the instrument panel above the glove box is the most visible
part of the passenger side airbag system. Located under the airbag door are the airbag cushion
and its supporting components. The airbag module includes a housing to which the cushion and
inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if
deployed or in any way damaged.
The inflator assembly is mounted to the back of the airbag module. The inflator includes a small
canister of highly compressed argon gas. The inflator seals the hole in the airbag cushion so it can
discharge the compressed gas it contains directly into the cushion when supplied with the proper
electrical signal. The airbag door is secured to the airbag module and the instrument panel base
trim, and has predetermined breakout lines concealed beneath its decorative cover. Upon airbag
deployment, the airbag door will split at the breakout lines and the door will pivot out of the way.
The airbag module is secured with screws at the rear to the instrument panel glove box opening
reinforcement, and at the front it is secured to a bracket on the instrument panel armature. The
airbag module and airbag door are available as separate service items. Following an airbag
deployment, the airbag module and airbag door must be replaced.
Storage An airbag module must be stored in its original, special container until used for service.
Also, it must be stored in a clean, dry environment; away from sources of extreme heat, sparks,
and high electrical energy. Always place or store an airbag module on a surface with its trim cover
or airbag side facing up, to minimize movement in case of an accidental deployment.

Air Bag Control Module: Description and Operation
SYSTEM OPERATION
The Airbag Control Module (ACM) is secured to a bracket on the floor panel underneath the driver
side front seat in the passenger compartment of the vehicle. The ACM contains a microprocessor
that contains the airbag system logic, the impact sensor, and an energy storage capacitor. The
ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the
instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag
indicator lamp.
The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical
circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends
messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A
pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration
rate signaled by the impact sensor indicates an impact that is severe enough to require airbag
system protection. When the programmed conditions are met, the ACM sends an electrical signal
to deploy the air-bag system components.
Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that
senses the rate of vehicle deceleration, which provides verification of the direction and severity of
an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit
with the ACM.
The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical
energy to deploy the airbags for up to one second following a battery disconnect or failure during
an impact. The purpose of the capacitor is to provide airbag system protection in a severe
secondary impact, if the initial impact has damaged or disconnected the battery, but was not
severe enough to deploy the airbags.
The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced.

DISCUSSION:
Airbag
When servicing any airbag system, it is essential to follow the proper Service Manual and/or
Diagnostic Manual procedures for diagnosing, testing, and replacing of any component. When
diagnosing any airbag squib circuit Diagnostic Trouble Code (DTC) with a DRBIII(R), the use of the
Airbag Load Tool (Special Tool 8310 and 8443) is required. The Airbag Load Tool, used in
conjunction with the DRBIII(R) are used to isolate and test components and wiring for failure. Only
replace the component or wiring that has failed. This will reduce unnecessary cost to the customer
or DaimlerChrysler.
NOTE:
AIRBAG REPLACEMENT IS NOT REQUIRED EVERY TIME IT IS REMOVED OR WHEN
ANOTHER COMPONENT HAS FAILED. USE OF THE DRBIII(R) AND AIRBAG LOAD TOOL
WILL DETERMINE IF THE AIRBAG HAS FAILED AND REPLACEMENT IS NEEDED.

TECHNICIANS SHOULD RECORD ALL STORED AND ACTIVE AIRBAG SYSTEM FAULT
CODES ON THE REPAIR ORDER.
Clock Springs
Recent analysis of returned clock springs have indicated that prior service may have contributed to
the clock spring's failure.
^ Do not use silicone or any other lubricant spray on or near the clock spring. Lubricants are often
used in the clock spring area of the steering column to eliminate noise. Lubricants may have an
adverse effect on the clock spring.
^ Clock spring centering. Any repair that may disrupt the positioning of the steering wheel with the
front wheels will require that the clock spring be centered. This includes clock spring replacement,
steering column service, HVAC service, steering gear service, and front suspension crossmember
service. Refer to the appropriate Service Manual for the clock spring centering procedure.

Clockspring Assembly / Spiral Cable: Description and Operation
SYSTEM OPERATION
The clockspring is used to maintain a continuous electrical circuit between the instrument panel
wire harness, the driver side airbag module, and the vehicle speed control switches on vehicles
that are so equipped. The clockspring is mounted on the steering column behind the steering
wheel. This assembly consists of a plastic housing which contains a flat, ribbon-like, electrically
conductive tape that winds and unwinds with the steering wheel rotation.
The clockspring must be properly centered when it is installed on the steering column following any
service removal, or it will be damaged. See Clockspring Centering in the Adjustments for the
procedures.
The clockspring cannot be repaired. If the clock-spring is faulty, damaged, or if the airbag has been
deployed, the clockspring must be replaced.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Clockspring Assembly / Spiral Cable, Air Bag >
Component Information > Technical Service Bulletins > Page 5435
Clockspring Assembly / Spiral Cable: Adjustments
The clockspring is designed to wind and unwind when the steering wheel is rotated, but is only
designed to rotate the same number of turns (about five complete rotations) as the steering wheel
can be turned from stop to stop. If the rotating tape within the clockspring is not indexed properly to
the steering wheel and the front wheels, the clockspring may become wound too tight and fail
during use. The clockspring must be centered if it is not known to be properly indexed, or if the
front wheels were moved from the straight-ahead position with the clockspring removed during any
service procedure.
WARNING: THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT.
BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED
STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU
MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE.
THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE
FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
1. Turn the steering wheel until the front wheels are in the straight-ahead position before starting
the centering procedure. 2. Disconnect and isolate the battery negative cable. If the airbag has not
been deployed, wait two minutes for the system capacitor to discharge
before further service.
3. Remove the clockspring from the steering column. See Clockspring Replacement.
Clockspring Centering
4. Hold the clockspring with the bottom side facing up and depress the spring lock. 5. Keeping the
spring lock depressed, rotate the clockspring hub counterclockwise to the end of its travel. Do not
apply excessive torque. 6. From the end of the counterclockwise travel, rotate the clockspring hub
about two and one-half turns clockwise, then release the spring lock
between the locking tabs.
7. The front wheels should still be in the straight ahead position. Reinstall the clockspring on the
steering column. See Clockspring Replacement.

Malfunction Lamp / Indicator: Description and Operation
SYSTEM OPERATION
The airbag indicator lamp gives an indication when the airbag system is faulty or inoperative. The
lamp is controlled by the instrument cluster circuitry based upon messages received from the
Airbag Control Module (ACM) on the Chrysler Collision Detection (CCD) data bus. The lamp is
turned on by the ACM for about seven seconds when the ignition switch is turned to the On
position as a bulb test.
The ACM continually monitors the airbag system circuits and sensors to decide whether the system
is in good operating condition. The ACM then sends the proper messages to the instrument cluster
on the CCD data bus to turn the lamp on or off. If the ACM turns the lamp on after the bulb test, it
indicates the ACM has detected a system malfunction and/or that the airbag system has become
inoperative. The instrument cluster circuitry will also send a chime request to the Central Timer
Module (CTM) when a lamp-on message is received from the ACM. A lamp-on message does not
mean that either or both airbags will not deploy upon an impact, only that they might not deploy,
depending upon the nature of the detected malfunction. Each time that the instrument cluster
circuitry receives a lamp-on message from the ACM, it will light the lamp for three seconds or the
duration of the airbag system malfunction, whichever is longer.
The airbag indicator lamp also has a lamp backup feature. About ten seconds after the ignition
switch is turned to the On position, if an inoperative airbag warning lamp circuit was detected
during the bulb test sequence, the instrument cluster circuitry will flash the seat belt reminder lamp
on and off for about thirty seconds. If the seat belt reminder lamp stays on after flashing for thirty
seconds, or comes on at any time other than about ten seconds after the initial ignition-on
sequence, it may indicate that an airbag system fault has been detected and that the airbag
indicator lamp is inoperative. See Seat Belt Reminder Lamp in the Description and Operation for
more information on the airbag lamp backup feature. Refer to Air Bag Systems for more
information on airbags.

Malfunction Lamp / Indicator: Testing and Inspection
The diagnosis found here addresses an inoperative airbag indicator lamp condition. If the airbag
indicator lamp stays on with the ignition switch in the On position, or comes on and stays on while
driving, refer to Air Bag Systems for diagnosis.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
The airbag indicator lamp has a lamp backup feature. Ten seconds after the ignition switch is
turned to the On position, if the instrument cluster circuitry has detected an inoperative airbag
warning lamp circuit it will flash the seat belt reminder lamp on and off for thirty seconds. Once the
instrument cluster circuitry has detected an inoperative airbag warning lamp circuit, if a lamp-on
message is received from the Airbag Control Module (ACM) on the Chrysler Collision Detection
(CCD) data bus, the seat belt reminder lamp will remain on for the duration of the airbag system
malfunction.
If the airbag indicator lamp fails to light when the ignition switch is turned to the On position, and
the seat belt reminder lamp flashes following its normal display function (about six seconds after
the ignition switch is turned to the On position), diagnosis of the airbag system and/or the CCD
data bus should be performed with a DRB scan tool as described in the proper Diagnostic
Procedures. For further diagnosis of the airbag indicator lamp and the instrument cluster circuitry,
see Instrument Cluster in the Diagnosis and Testing.

Air Bag Control Module: Description and Operation
SYSTEM OPERATION
The Airbag Control Module (ACM) is secured to a bracket on the floor panel underneath the driver
side front seat in the passenger compartment of the vehicle. The ACM contains a microprocessor
that contains the airbag system logic, the impact sensor, and an energy storage capacitor. The
ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the
instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag
indicator lamp.
The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical
circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends
messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A
pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration
rate signaled by the impact sensor indicates an impact that is severe enough to require airbag
system protection. When the programmed conditions are met, the ACM sends an electrical signal
to deploy the air-bag system components.
Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that
senses the rate of vehicle deceleration, which provides verification of the direction and severity of
an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit
with the ACM.
The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical
energy to deploy the airbags for up to one second following a battery disconnect or failure during
an impact. The purpose of the capacitor is to provide airbag system protection in a severe
secondary impact, if the initial impact has damaged or disconnected the battery, but was not
severe enough to deploy the airbags.
The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced.

REMOVAL AND INSTALLATION
WARNING:
- THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE
SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY
AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT
PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR
TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO
DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
- NEVER STRIKE OR KICK THE AIR BAG CONTROL MODULE, AS IT CAN DAMAGE THE
IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS
ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND
REPLACED WITH A NEW UNIT. ALWAYS REINSTALL THE AIRBAG CONTROL MODULE
PROTECTIVE COVER.
1. Disconnect and isolate the battery negative cable. If the airbag has not been deployed, wait two
minutes for the system capacitor to discharge
before further service.
2. Reach under the driver side front seat to access and unplug the wire harness connector from the
Air-Bag Control Module (ACM).
Airbag Control Module Remove/Install
3. Remove the three screws that secure the ACM to the mounting bracket on the floor panel under
the driver seat. 4. Remove the ACM from the floor panel mounting bracket. 5. When installing the
ACM, position the unit with the arrow on the ACM housing pointing forward. 6. Secure the ACM to
the floor panel mounting bracket with the three mounting screws. Tighten the mounting screws to
11.8 N.m (105 in. lbs.). 7. Plug in the wire harness connector to the ACM. Be certain that the
connector latches are fully engaged. 8. Do not connect the battery negative cable at this time. See
Airbag System in the Diagnosis and Testing.

Air Bag(s) Arming and Disarming: Service Precautions
WARNING: The airbag system is a sensitive, complex electro-mechanical unit. Before attempting
to diagnose, remove or install the airbag system components you must first disconnect and isolate
the battery negative (ground) cable. Failure to do so could result in accidental deployment of the
airbag and possible personal injury. The fasteners, screws, and bolts, originally used for the airbag
components, have special coatings and are specifically designed for the airbag system. They must
never be replaced with any substitutes. Anytime a new fastener is needed, replace with the correct
fasteners provided in the service package or fasteners listed in the parts books
.

Seat Belt Reminder Lamp: Description and Operation
SYSTEM OPERATION
The seat belt reminder lamp gives a visual reminder to the vehicle occupants to fasten their seat
belts. The lamp is turned on by the instrument cluster circuitry for about seven seconds when the
ignition switch is turned to the On position.
The instrument cluster also receives a hard wired input from the driver seat belt switch. However,
this input only affects the chime function and has no effect on the seat belt reminder lamp
operation. If the driver seat belt switch is closed (seat belt is not buckled), the instrument cluster will
send a chime request to the Central Timer Module (CTM) lasting the duration of the seat belt
reminder lamp illumination. The chime warning will stop when the driver seat belt switch is open
(seat belt is buckled).
The seat belt reminder lamp also serves as a backup for the airbag indicator lamp. About twenty
seconds after the ignition switch is turned to the On position, if an inoperative airbag indicator lamp
circuit was detected during the bulb test sequence, the instrument cluster circuitry will flash the seat
belt reminder lamp on and off for about thirty seconds. If the seat belt reminder lamp stays on after
flashing for thirty seconds, or comes on at any time other than about twenty seconds after the initial
ignition-on sequence, it indicates an airbag system fault has been detected and that the airbag
indicator lamp is inoperative.
Refer to Air Bags and Seat Belts/Air Bags for more information on the airbag system.

Seat Belt Reminder Lamp: Testing and Inspection
The diagnosis found here addresses an inoperative seat belt reminder lamp condition. If the lamp
comes on and flashes following its display function (about ten seconds after the ignition switch is
turned to the On position), it indicates an inoperative airbag indicator lamp. Refer to Restraint
Systems/Air Bag Systems/Testing and Inspection for additional testing procedures. See: Air Bag
Systems/Testing and Inspection
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
If the seat belt reminder lamp fails to light during its normal display function (about six seconds
after the ignition switch is turned to the On position), see Instrument Cluster in the Diagnosis and
Testing for further diagnosis. This lamp is completely controlled by the instrument cluster circuitry.
On models equipped with a Central Timer Module, the hard wired seat belt switch input to the
instrument cluster has no control over the seat belt reminder lamp function and is only used by the
instrument cluster circuitry as a reference for its chime request function.

Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Description and
Operation
Antenna: Description and Operation
SYSTEM OPERATION
All models use a fixed-length stainless steel rod- type antenna mast, installed at the right front
fender of the vehicle. The antenna mast has a spiral groove cut down its length to reduce wind
noise.
The antenna mast is connected to the center wire of the coaxial antenna cable, and is not
grounded to any part of the vehicle. To eliminate static, the antenna base must have a good
ground. The coaxial antenna cable shield (the outer wire mesh of the cable) is grounded to the
antenna base and the radio chassis.
The antenna coaxial cable has an additional disconnect, located on the outboard side of the right
instrument panel end bracket and hidden beneath the passenger side instrument panel end cap.
This additional disconnect allows the instrument panel assembly to be removed and installed
without removing the radio.
The factory-installed Electronically Tuned Radios (ETRs) automatically compensate for radio
antenna trim. Therefore, no antenna trimmer adjustment is required or possible when replacing the
receiver or the antenna.

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
The following four tests are used to diagnose the antenna with an ohmmeter:
- Test 1 - Mast to ground test
- Test 2 - Tip-of-mast to tip-of-conductor test
- Test 3 - Body ground to battery ground test
- Test 4 - Body ground to coaxial shield test.
Antenna Tests
The ohmmeter test lead connections for each test are shown in Antenna Tests.
NOTE: This model has a two-piece antenna coaxial cable. Tests 2 and 4 must be conducted in two
steps to isolate a coaxial cable problem; from the coaxial cable connection on the right end bracket
of the instrument panel near the right cowl side inner panel to the antenna base, and then from the
coaxial cable connection to the radio chassis connection.
Test 1 Test 1 determines if the antenna mast is insulated from the base. Proceed as follows: 1.
Unplug the antenna coaxial cable connector from the radio chassis and isolate. 2. Connect one
ohmmeter test lead to the tip of the antenna mast. Connect the other test lead to the antenna base.
Check for continuity. 3. There should be no continuity If continuity is found, replace the faulty or
damaged antenna base and cable assembly
Test 2 Test 2 checks the antenna for an open circuit as follows: 1. Unplug the antenna coaxial
cable connector from the radio chassis. 2. Connect one ohmmeter test lead to the tip of the
antenna mast. Connect the other test lead to the center pin of the antenna coaxial cable connector.
3. Continuity should exist (the ohmmeter should only register a fraction of an ohm). High or infinite
resistance indicates damage to the base and cable
assembly Replace the faulty base and cable, if required.
Test 3 Test 3 checks the condition of the vehicle body ground connection. This test should be
performed with the battery positive cable removed from the battery Disconnect both battery cables,
the negative cable first. Reconnect the battery negative cable and perform the test as follows: 1.
Connect one ohmmeter test lead to the vehicle fender. Connect the other test lead to the battery
negative post. 2. The resistance should be less than one ohm. 3. If the resistance is more than one
ohm, check the braided ground strap connected to the engine and the vehicle body for being loose,
corroded, or
damaged. Repair the ground strap connection, if required.
Test 4 Test 4 checks the condition of the ground between the antenna base and the vehicle body
as follows: 1. Connect one ohmmeter test lead to the vehicle fender. Connect the other test lead to
the outer crimp on the antenna coaxial cable connector. 2. The resistance should be less then one
ohm. 3. If the resistance is more then one ohm, clean and/or tighten the antenna base to fender
mounting hardware.

Keyless Entry Receiver: Description and Operation
SYSTEM OPERATION
The Remote Keyless Entry (RKE) receiver is a radio frequency unit that is integral to the power
lock and RKE module or to the Central Timer Module (CTM). The RKE receiver has a memory
function to retain the vehicle access codes of the RKE transmitters, even if the battery is
disconnected. The power lock and RKE module can store two transmitter vehicle access codes,
the CTM can store up to four.
The RKE receiver is energized by one of two radio frequency inputs from the RKE transmitter,
Unlock or Lock. The programming of the power lock and RKE module or the CTM responds to
these RKE inputs, as well as many other inputs, by sending the proper control outputs to the power
lock motors, the courtesy lamp circuit, and (with the CTM-based RKE system only) the horn relay.
The RKE receiver is only serviced as a unit with the power lock and RKE module or the CTM and,
if faulty or damaged, the module unit must be replaced.

Security Lamp/Indicator: Description and Operation
SYSTEM OPERATION
The security lamp gives an indication of the status of the optional Vehicle Theft Security System
(VTSS). The lamp is controlled by a hard wired input to the instrument cluster from the high-line
Central Timer Module (CTM). The lamp is turned on by the CTM for about two seconds when the
ignition switch is turned to the On position as a bulb test.
After the bulb test, the CTM turns the lamp on or off based upon the arming status of the VTSS. If
the security lamp stays on for about thirty seconds after the ignition switch is turned to the On
position, it indicates that Chrysler Collision Detection (CCD) data bus communication with the
Powertrain Control Module (PCM) is inoperative, and that the next attempt to arm the VTSS may
not be successful.
Refer to Accessories and Optional Equipment/Antitheft and Alarm/Vehicle Theft/Security Systems
for more information on the VTSS and the security lamp.
The security lamp is an amber lamp located within the instrument cluster on the instrument panel.
The security lamp receives fused battery feed at all times and is grounded by the high line Central
Timer Module (CTM) to give a visible indication of the Vehicle Theft Security System (VTSS)
arming status.
The security lamp incandescent bulb and bulb holder can be serviced. Refer to Instrument Panel,
Gauges and Warning Indicators/Cluster Bulbs Service Procedures.

The following is excerpted from the owners manual of new DaimlerChrysler products:
"INSTALLATION OF RADIO TRANSMITTING EQUIPMENT
Special design considerations are incorporated into this vehicle's electronic system to provide
immunity to radio frequency signals. Mobile two-way radio and telephone equipment must be
installed properly by trained personnel. The following must be observed during installation.
The positive power connection should be made directly to the battery and fused as close to the
battery as possible. The negative power connection should be made to body sheet metal adjacent
to the negative battery connection. This connection should not be fused.
Antennas for two-way radios should be mounted on the roof or the rear area of the vehicle. Care
should be used in mounting antennas with magnet bases. Magnets may affect the accuracy or
operation of the compass on vehicles so equipped.
The antenna cable should be as short as practical and routed away from the vehicle wiring when
possible. Use only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to ensure a low Standing Wave Ratio (SWR).
Mobile radio equipment with output power greater than normal may require special precautions.
All installations should be checked for possible interference between the communications
equipment and the vehicle's electronic systems. A Technical Service Bulletin (TSB) is available for
detailed assistance."
The owner's first line of contact regarding vehicle problems is the dealer. The literature supplied
with each vehicle lists the steps to be taken in the event the dealer is unable to resolve the
problem. To assist in properly installing communications equipment in DaimlerChrysler vehicles,
the following information is provided. Always use good construction practices (see The ARRL
Handbook or other standard reference works).
The information contained in this guide has been prepared for use by persons installing two-way
radio equipment (transmitters and receivers) in vehicles. It has been prepared in accordance with
current engineering principles and generally accepted practices, using the best information
available at the time of publication. It is not possible to cover all of the possible installations of
two-way radio equipment in this guide. Accordingly, DaimlerChrysler Corporation cannot be held
responsible for incidental or consequent damages arising out of the use of the information
contained herein. The responsibility for installations and modifications is the sole responsibility of
the customer.
The installation recommendations presented here are intended to supplement the radio
manufacturer's instructions. Test the entire installation for anomalies, especially drivetrain and
brake control before extensive driving.
1. CONTROLS Mount the transceiver to a solid surface. If you use screws through the floor pan,
put body sealer over the underbody projections. (Stamped acorn nuts, filled with sealer are
available at most body shops for this purpose.) This will keep moisture out of the carpet and
insulation, and will forestall rust in this area. Watch out for wire harnesses routed under carpet and
behind instrument panel.
If you mount the radio under the instrument panel, be sure that there is no interference with proper
operation of the foot controls. Mount the control head or front panel (especially the microphone
cable) so that it is clear of the steering wheel and column controls and passenger airbag. If the unit
is heavy, extra bracing may be needed for stability. Newer vehicles have more structure and
energy absorbing materials in the knee blocker (the lower part of the Instrument Panel).
For one-piece transceivers, if ignition switch control is desired, it is good practice to use a power
relay to avoid overloading the ignition switch, and to maintain the advantages of direct battery feed.
Try the installation out before you start drilling holes.
2. POWER WIRING To reduce the hazard of working on the vehicle, disconnect the battery
NEGATIVE before beginning work. Note that some components may lose short-term memory (e.g.:
radio presets) after a protracted time without battery power.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Accessories and Optional Equipment > Cellular Phone > Component Information > Technical
Service Bulletins > Radio Communication Equipment - Recommendations > Page 5587
For low or medium power transmitters (up to 55W FM or 110W SSB or CW), the power outlet or
cigar lighter feed may be used. Use a 1/4" jumper terminal at the socket or splice (solder and heat
shrink or tape). For higher power transmitters, including amplifiers, connect the power (battery +)
lead at the battery or at the power distribution center or at the positive jump-start post, if the vehicle
has one. An appropriate terminal should be used. If the terminal is exposed to the weather, solder
and apply a commercial protectant (wheel bearing grease is an acceptable alternative.) to retard
corrosion. This lead should be fused as close to the battery as practical to protect the wiring (and
the vehicle)! If the power connection is underhood, use a weatherproof fuse holder. Motorola
Communications Division supplies a weatherproof holder, part number 09-84277B01 for 5AG
cartridge fuses that is part of their standard installation kit. Packard Electric Division of Delphi
Automotive Systems makes an insulator, part number 12033769, terminal number 12020156 with
cover 12033731 for standard SAE plastic fuses.
Vinyl-insulated wire, typically supplied with transceivers is not entirely suitable for the higher
underhood temperatures in modern vehicles. Route underhood wiring away from all hot areas.
Body sheet metal, away from the exhaust, radiator, A/C liquid line and engine is usually the coolest
location.
DO NOT FUSE THE GROUND LEAD. If the ground-side fuse were to open, the entire supply
current would be conducted by an alternate current return path, which could cause the feedline to
overheat, with possible resulting damage.
For low or medium power installations, connect the ground (battery -) to body sheet near the power
feed point. If you use a screw through the floor, put body sealer over the underbody projection.
(Stamped acorn nuts, filled with sealer are available at most body shops for this purpose.) For high
power installations, connect the ground (battery -) lead at the battery connection to the body. This
is usually a 6 or 8 AWG black wire from the battery negative terminal to a screw at the wheelhouse
or radiator support. If a separate sheet metal ground is used, clean the paint off a one inch or so
diameter area of body panel where the ground lead is to be connected (usually the case with
commercial trunk mount radios). An awl is the best tool to use to pierce a starting hole for a #12 or
5mm, minimum plated ground screw. A ring terminal with lockwasher serrations of the proper size
for the screw or a separate serrated (not a split or SAE) lockwasher should be used between the
terminal and the screw head. As above, some grease or protectant should be used if the
connection is in an unprotected area.
If the power cable must pass through the dash panel, try to find an existing hole with a grommet
that is unused. If none is available, pull the carpet back from under the dash panel in the passenger
footwell in the cabin. Locate a place where there are no other components on either side, as high
up as possible. An awl is the best tool to use to punch a small hole through to the engine
compartment. If the position is good, enlarge the hole by driving the awl in up to the shank. If this is
not large enough to easily pass the cable, enlarge it by using a larger tapered punch. This will
leave an extruded hole with no sharp edges. Install the cable and seal the hole with silicone RTV or
commercial body sealer on both sides. Seal any extra holes that you may have made. Dress the
underhood wiring so that it is sate from all hazards, which include the following: exhaust manifold,
steering shaft, throttle linkage, fans, etc. Tie wrap as required.
3. CABLING Route control cables under the floor mats, inside the corner where the floor pan meets
the rocker panel for best protection. Remove the sill plates and tuck the cable under the floor mats
or carpet and padding. For most left hand drive vehicles, use the right side for best separation to
the main body harness (usually on the left side).
Route the cable along the extreme outboard edge of the floor pan, under the side trim, if possible.
4. REMOTE TRANSCEIVER For trunk mount installations in passenger cars, you may need to
remove the rear seat cushion and seat back to get the cable into the trunk. The seat cushion is
usually clipped at the front, lower edge by its own frame: push down and back, then lift. Note the
front and rear clipping points for ease of reinstallation. The seat back is usually clipped to the rear
compartment inner panel: pull out at the bottom and slide up to remove. Again, note the clipping
points for ease of reinstallation. There is usually a vapor/sound barrier behind the seat back, which
must be pierced to pass the cable.
Open the trunk and pick a spot where the cable is safe from chafing on any sharp sheet metal. Tie
wrap or tape in place at this location. Repair the barrier sheet if necessary. Replace the seat back
and cushion, taking care that the cable is not pinched by the seat cushion when there is someone
sitting in the seat. On some vehicles, there may be a channel for wiring at this location.
For remote control radios, a sheet of 1/2 in. plywood one or two inches larger than the radio, is a
good method to mount the transceiver to the shelf. It provides a good mounting surface, some
shock and vibration isolation, and it keeps moisture away from the radio. Mounting on the floor of
the trunk is not recommended. To conserve trunk space, in some vehicles, the radio may be
mounted to the rear compartment panel. Locate as far as possible from any vehicle electronic
modules located in the rear of the vehicle.
In any case, provide good air circulation; a 50 watt RF output FM transmitter will dissipate about 22
watts (@70% efficiency). Do not pile things on top of the unit.
5. TRANSMISSION LINE The transmission line (coaxial cable) should be treated in the same way
as the control and power cables. Route flat along body sheet metal wherever possible to avoid
sharp edges and pinches. If it is necessary to cross over wiring, cross at right angles. In some
cases, additional shielding between the transmission line and the vehicle wiring may be helpful. It is
important to maintain the maximum spacing from the vehicle harnesses, especially if the antenna is
not a good match. Use the best cable available (98-99% braid coverage or braid/foil) especially at
UHF and above. Mechanical pressure on the cable can cause degradation or even short circuits.
Do not rely on the obsolete military "RG" designations as an indicator of quality.
Cut off, do not coil excess transmission line (This forms a choke balun.) and terminate in the
correct connector.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))
Dodge Workshop Manuals > Accessories and Optional Equipment > Cellular Phone > Component Information > Technical
Service Bulletins > Radio Communication Equipment - Recommendations > Page 5588
The use of N, BNC or C connectors is recommended over "UHF" (PL-259/S0-239) connectors. A
small amount of silicone dielectric grease (not the white heat sink compound) in the connector
(after soldering) will minimize condensation problems. Cut the line as short as practical, to minimize
losses.
6. ANTENNA LOCATION Antenna location is the most important consideration in any mobile
installation. For VHF and UHF antennas the recommended place on almost all vehicles is in the
center of the roof. The center of the deck lid is an acceptable alternate. Glass-mounted antennas
should be mounted at the very top edge of the clear portion of the glass away from the heater grid.
Vehicles with printed-on-glass antennas may be damaged by through-glass installations.
For HF antennas, refer to the manufacturer's instructions and follow them closely, unless you are
an accomplished antenna experimenter. HF antennas should be mounted to body or frame steel
for a good counterpoise as well as structural strength. Aluminum bumpers are heavily anodized for
corrosion protection, and the coating (aluminum oxide) is very hard as well as nonconductive. A
small grinder with a coarse stone will break through the anodized coating for electrical connection.
7. ANTENNA INSTALLATION Permanently installed antennas are preferable over magnetic, glass
or body-lip mounts for anything other than for low power or temporary installations. Most of these
alternate antennas will reflect some power back at the feedpoint. Much of this will be radiated from
the feedline inside the passenger compartment, and may be picked up by the vehicle wiring.
For deck lid installations, the deck lid must be bonded to the body, across the hinges, with short,
wide tinned braid straps. They must connect to clean sheet metal at both ends. For AM/SSB and
even some FM installations, the hood must be bonded to the body. In some cases the doors may
need to be bonded, as well.
Glass-mount antennas will not work or will only work very poorly in vehicles with metallized glass
(Electrically-heated windshields or some solar reflective glass). Non-metallic bodies (e.g., Viper)
require a half-wavelength antenna or a ground plane with radius approximately equal to the length
of a quarter-wave antenna. Copper is the best choice, but aluminum or even steel may be used.
Install on the inside of the body panel with a good adhesive or tape and provide a good RF
connection to the coax shield at the feedpoint. Screen, mesh or thin sheet stock may be used.
Shape is not critical, but some directional characteristics may be noted if it is not round. Try to stay
one-quarter wavelength away from edges, including sunroof openings. Consider the sunroof
mechanism for interference to the base and to the feedline.
For VHF and UHF, a good quality "NMO" (New Motorola) base or other mount with feedline (center
conductor and shield) soldered to base is recommended. This will allow the maximum flexibility in
antenna selection and is the best choice for electrical and mechanical considerations. Use the
proper hole saw (3/4 in. for NMO) or have it done professionally if you are not comfortable with
power tools. Hole plugs are available, for use at sale or trade-in, if you expect to remove the
antenna base.
To install the antenna base in the hole, remove the one or two-door trim pieces at the pillar where
the cable is to be routed and ease the headliner away from the roof. Insert a piece of flat steel or
plastic banding (1/2 in. to 3/4 in. wide) and guide to the desired corner. Pull the banding through,
leaving 6 in., which can be taped, to the transmission line (easier without the connector, but
possible even with a PL-259). Continue pulling until the antenna base is one inch or less from the
hole, then seat the base and screw on the outside ring, 0-ring down. A little silicone grease helps
maintain a good seal for the life of the vehicle. Tighten with an open-end wrench, and apply a small
amount of silicone grease to the contact and insulator surface of the base. This will help exclude
water, but must be renewed periodically. Tip: if you remove your antenna to go through the car
wash, there are caps available to exclude water during the process.
In most vehicles, RG-58-sized cable will fit between the pillar trim and body sheet metal. If
necessary, the technique used on the roof can also be used to snake the cable down the inside the
pillar.
Install the connector very carefully. There are good instructions in The ARRL Handbook. Use a
clean, hot, high-wattage iron and work quickly, to prevent damage to the cable dielectric. If you are
a beginner or are not comfortable with this kind of detail work, ask for help. It is extremely
important.

relay to avoid overloading the ignition switch, and to maintain the advantages of direct battery feed.
Try the installation out before you start drilling holes.
2. POWER WIRING To reduce the hazard of working on the vehicle, disconnect the battery
NEGATIVE before beginning work. Note that some components may lose short-term memory (e.g.:
radio presets) after a protracted time without battery power.

For low or medium power transmitters (up to 55W FM or 110W SSB or CW), the power outlet or
cigar lighter feed may be used. Use a 1/4" jumper terminal at the socket or splice (solder and heat
shrink or tape). For higher power transmitters, including amplifiers, connect the power (battery +)
lead at the battery or at the power distribution center or at the positive jump-start post, if the vehicle
has one. An appropriate terminal should be used. If the terminal is exposed to the weather, solder
and apply a commercial protectant (wheel bearing grease is an acceptable alternative.) to retard
corrosion. This lead should be fused as close to the battery as practical to protect the wiring (and
the vehicle)! If the power connection is underhood, use a weatherproof fuse holder. Motorola
Communications Division supplies a weatherproof holder, part number 09-84277B01 for 5AG
cartridge fuses that is part of their standard installation kit. Packard Electric Division of Delphi
Automotive Systems makes an insulator, part number 12033769, terminal number 12020156 with
cover 12033731 for standard SAE plastic fuses.
Vinyl-insulated wire, typically supplied with transceivers is not entirely suitable for the higher
underhood temperatures in modern vehicles. Route underhood wiring away from all hot areas.
Body sheet metal, away from the exhaust, radiator, A/C liquid line and engine is usually the coolest
location.
DO NOT FUSE THE GROUND LEAD. If the ground-side fuse were to open, the entire supply
current would be conducted by an alternate current return path, which could cause the feedline to
overheat, with possible resulting damage.
For low or medium power installations, connect the ground (battery -) to body sheet near the power
feed point. If you use a screw through the floor, put body sealer over the underbody projection.
(Stamped acorn nuts, filled with sealer are available at most body shops for this purpose.) For high
power installations, connect the ground (battery -) lead at the battery connection to the body. This
is usually a 6 or 8 AWG black wire from the battery negative terminal to a screw at the wheelhouse
or radiator support. If a separate sheet metal ground is used, clean the paint off a one inch or so
diameter area of body panel where the ground lead is to be connected (usually the case with
commercial trunk mount radios). An awl is the best tool to use to pierce a starting hole for a #12 or
5mm, minimum plated ground screw. A ring terminal with lockwasher serrations of the proper size
for the screw or a separate serrated (not a split or SAE) lockwasher should be used between the
terminal and the screw head. As above, some grease or protectant should be used if the
connection is in an unprotected area.
If the power cable must pass through the dash panel, try to find an existing hole with a grommet
that is unused. If none is available, pull the carpet back from under the dash panel in the passenger
footwell in the cabin. Locate a place where there are no other components on either side, as high
up as possible. An awl is the best tool to use to punch a small hole through to the engine
compartment. If the position is good, enlarge the hole by driving the awl in up to the shank. If this is
not large enough to easily pass the cable, enlarge it by using a larger tapered punch. This will
leave an extruded hole with no sharp edges. Install the cable and seal the hole with silicone RTV or
commercial body sealer on both sides. Seal any extra holes that you may have made. Dress the
underhood wiring so that it is sate from all hazards, which include the following: exhaust manifold,
steering shaft, throttle linkage, fans, etc. Tie wrap as required.
3. CABLING Route control cables under the floor mats, inside the corner where the floor pan meets
the rocker panel for best protection. Remove the sill plates and tuck the cable under the floor mats
or carpet and padding. For most left hand drive vehicles, use the right side for best separation to
the main body harness (usually on the left side).
Route the cable along the extreme outboard edge of the floor pan, under the side trim, if possible.
4. REMOTE TRANSCEIVER For trunk mount installations in passenger cars, you may need to
remove the rear seat cushion and seat back to get the cable into the trunk. The seat cushion is
usually clipped at the front, lower edge by its own frame: push down and back, then lift. Note the
front and rear clipping points for ease of reinstallation. The seat back is usually clipped to the rear
compartment inner panel: pull out at the bottom and slide up to remove. Again, note the clipping
points for ease of reinstallation. There is usually a vapor/sound barrier behind the seat back, which
must be pierced to pass the cable.
Open the trunk and pick a spot where the cable is safe from chafing on any sharp sheet metal. Tie
wrap or tape in place at this location. Repair the barrier sheet if necessary. Replace the seat back
and cushion, taking care that the cable is not pinched by the seat cushion when there is someone
sitting in the seat. On some vehicles, there may be a channel for wiring at this location.
For remote control radios, a sheet of 1/2 in. plywood one or two inches larger than the radio, is a
good method to mount the transceiver to the shelf. It provides a good mounting surface, some
shock and vibration isolation, and it keeps moisture away from the radio. Mounting on the floor of
the trunk is not recommended. To conserve trunk space, in some vehicles, the radio may be
mounted to the rear compartment panel. Locate as far as possible from any vehicle electronic
modules located in the rear of the vehicle.
In any case, provide good air circulation; a 50 watt RF output FM transmitter will dissipate about 22
watts (@70% efficiency). Do not pile things on top of the unit.
5. TRANSMISSION LINE The transmission line (coaxial cable) should be treated in the same way
as the control and power cables. Route flat along body sheet metal wherever possible to avoid
sharp edges and pinches. If it is necessary to cross over wiring, cross at right angles. In some
cases, additional shielding between the transmission line and the vehicle wiring may be helpful. It is
important to maintain the maximum spacing from the vehicle harnesses, especially if the antenna is
not a good match. Use the best cable available (98-99% braid coverage or braid/foil) especially at
UHF and above. Mechanical pressure on the cable can cause degradation or even short circuits.
Do not rely on the obsolete military "RG" designations as an indicator of quality.
Cut off, do not coil excess transmission line (This forms a choke balun.) and terminate in the
correct connector.
Dodge Ram 1500 Van Workshop Manual (V8-5.9L VIN Z (1998))

Technical Service Bulletins > Radio Communication Equipment - Recommendations > Page 5595
The use of N, BNC or C connectors is recommended over "UHF" (PL-259/S0-239) connectors. A
small amount of silicone dielectric grease (not the white heat sink compound) in the connector
(after soldering) will minimize condensation problems. Cut the line as short as practical, to minimize
losses.
6. ANTENNA LOCATION Antenna location is the most important consideration in any mobile
installation. For VHF and UHF antennas the recommended place on almost all vehicles is in the
center of the roof. The center of the deck lid is an acceptable alternate. Glass-mounted antennas
should be mounted at the very top edge of the clear portion of the glass away from the heater grid.
Vehicles with printed-on-glass antennas may be damaged by through-glass installations.
For HF antennas, refer to the manufacturer's instructions and follow them closely, unless you are
an accomplished antenna experimenter. HF antennas should be mounted to body or frame steel
for a good counterpoise as well as structural strength. Aluminum bumpers are heavily anodized for
corrosion protection, and the coating (aluminum oxide) is very hard as well as nonconductive. A
small grinder with a coarse stone will break through the anodized coating for electrical connection.
7. ANTENNA INSTALLATION Permanently installed antennas are preferable over magnetic, glass
or body-lip mounts for anything other than for low power or temporary installations. Most of these
alternate antennas will reflect some power back at the feedpoint. Much of this will be radiated from
the feedline inside the passenger compartment, and may be picked up by the vehicle wiring.
For deck lid installations, the deck lid must be bonded to the body, across the hinges, with short,
wide tinned braid straps. They must connect to clean sheet metal at both ends. For AM/SSB and
even some FM installations, the hood must be bonded to the body. In some cases the doors may
need to be bonded, as well.
Glass-mount antennas will not work or will only work very poorly in vehicles with metallized glass
(Electrically-heated windshields or some solar reflective glass). Non-metallic bodies (e.g., Viper)
require a half-wavelength antenna or a ground plane with radius approximately equal to the length
of a quarter-wave antenna. Copper is the best choice, but aluminum or even steel may be used.
Install on the inside of the body panel with a good adhesive or tape and provide a good RF
connection to the coax shield at the feedpoint. Screen, mesh or thin sheet stock may be used.
Shape is not critical, but some directional characteristics may be noted if it is not round. Try to stay
one-quarter wavelength away from edges, including sunroof openings. Consider the sunroof
mechanism for interference to the base and to the feedline.
For VHF and UHF, a good quality "NMO" (New Motorola) base or other mount with feedline (center
conductor and shield) soldered to base is recommended. This will allow the maximum flexibility in
antenna selection and is the best choice for electrical and mechanical considerations. Use the
proper hole saw (3/4 in. for NMO) or have it done professionally if you are not comfortable with
power tools. Hole plugs are available, for use at sale or trade-in, if you expect to remove the
antenna base.
To install the antenna base in the hole, remove the one or two-door trim pieces at the pillar where
the cable is to be routed and ease the headliner away from the roof. Insert a piece of flat steel or
plastic banding (1/2 in. to 3/4 in. wide) and guide to the desired corner. Pull the banding through,
leaving 6 in., which can be taped, to the transmission line (easier without the connector, but
possible even with a PL-259). Continue pulling until the antenna base is one inch or less from the
hole, then seat the base and screw on the outside ring, 0-ring down. A little silicone grease helps
maintain a good seal for the life of the vehicle. Tighten with an open-end wrench, and apply a small
amount of silicone grease to the contact and insulator surface of the base. This will help exclude
water, but must be renewed periodically. Tip: if you remove your antenna to go through the car
wash, there are caps available to exclude water during the process.
In most vehicles, RG-58-sized cable will fit between the pillar trim and body sheet metal. If
necessary, the technique used on the roof can also be used to snake the cable down the inside the
pillar.
Install the connector very carefully. There are good instructions in The ARRL Handbook. Use a
clean, hot, high-wattage iron and work quickly, to prevent damage to the cable dielectric. If you are
a beginner or are not comfortable with this kind of detail work, ask for help. It is extremely
important.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers.
- Connectors located on the instrument panel harness are C200 series numbers.
- Connectors located on the body harness are C300 series numbers.

- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.
- ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE
CLOTHING.
Positive Temperature Coefficient
Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's
act like a solid state fuse. They are located in the

junction block, and are used to protect such items as: power door lock motors, power windows, and
various engine solenoids.
Positive Temperature Coefficient Symbol
A special symbol is used to identify these in the wiring diagrams.
Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

International symbols are used throughout the wiring diagrams. These symbols are consistent with
those being used around the world.
Take-Outs
The abbreviation T/O is used in the Component Location group to indicate a point at which the
wiring harness branches out to a component.
How to Find System & Component Diagrams
When trying to find the diagram for a specific component or system, use the Group Index
information or the Alphabetic Index to Wiring Diagrams under Electrical
Whenever a reference exists to another sheet or figure, find the corresponding diagram using the
Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number
for the subsequent diagram will match a listed group shown.

Wire Repair
When replacing or repairing a wire, it is important that the correct gauge be used as shown in the
wiring diagrams. The wires must also be held securely in place to prevent damage to the insulation.
1. Disconnect the battery negative cable.
2. Remove 1 inch of insulation from each end of the wire.
3. Place a piece of heat-shrink tubing over one side of the wire. Be sure the tubing will be long
enough to cover and seal the entire repair area.
4. Spread the strands of the wire apart on each part of the exposed wires (Example 1).
5. Push the two ends of wire together until the strands of wire are close to the insulation (Example
2).
6. Twist the wires together (Example 3).
7. Solder the connection together using rosin core solder only. Do not use acid core solder.
8. Center the heat-shrink tubing over the joint and heat using a heat gun. Heat the joint until the
tubing is tightly sealed and sealant comes out of both
ends of the tubing.
9. Secure the wire to the existing ones to prevent chafing or damage to the insulation.
10. Connect the battery and test all affected systems.

Radio/Stereo: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation
Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of
the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check
voltage. Refer to the
appropriate test procedure.

Component Information > Diagrams > Diagram Information and Instructions > Page 5624
Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.

Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Trailer Connector: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation
Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage

Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.

Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of
the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check
voltage. Refer to the
appropriate test procedure.

Diagrams > Diagram Information and Instructions > Page 5723
Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Body Control Module: Description and Operation Central Timer Module Description
The AB HIGH LINE utilize a Central Timer Module (CTM). The Base AB RAM VAN will not be
addressed in this manual. For concerns about the Base AB VAN, please refer to the appropriate
service and repair article. The CTM performs most of the typical functions a Body Control Module
would perform.
The CTM provides the following features:
- Remote Keyless Entry (RKE)
- Chime
- Courtesy Lamp controls/Illuminated Entry
- Power Door Locks WIRKE
- Speed Sensitive Intermittent Wipers
- Enhanced Accident Response
- Vehicle Theft Security System (VTSS)
The module is located on the left center instrument panel support. It contains a white 18-way and a
green 14-way connector.

Body Control Module: Description and Operation System Description and Functional Operation
The body system on the 1998 AB HIGH LINE consists of three modules that communicate over the
CCD bus (Chrysler Collision Detection multiplex system). There are two additional modules, the
Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the
body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for
diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are
performed through the Serial Communication Interface of SCI, the same as previous years. All of
the information about the functioning of all the system is organized, controlled, and communicated
by the CCD bus, which is described in Section 3 (CCD Bus) of this general information section.
Through the CCD bus, information about the operation of vehicle components and circuits is
relayed quickly to the appropriate module(s). All modules receive all the information transmitted on
the bus even though a module may not require all the information to perform it's function. It will only
respond to messages "addressed" to it through a binary coding process. This method of data
transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring
harnesses.

Keyless Entry Receiver: Description and Operation
SYSTEM OPERATION
The Remote Keyless Entry (RKE) receiver is a radio frequency unit that is integral to the power
lock and RKE module or to the Central Timer Module (CTM). The RKE receiver has a memory
function to retain the vehicle access codes of the RKE transmitters, even if the battery is
disconnected. The power lock and RKE module can store two transmitter vehicle access codes,
the CTM can store up to four.
The RKE receiver is energized by one of two radio frequency inputs from the RKE transmitter,
Unlock or Lock. The programming of the power lock and RKE module or the CTM responds to
these RKE inputs, as well as many other inputs, by sending the proper control outputs to the power
lock motors, the courtesy lamp circuit, and (with the CTM-based RKE system only) the horn relay.
The RKE receiver is only serviced as a unit with the power lock and RKE module or the CTM and,
if faulty or damaged, the module unit must be replaced.

Power Door Lock Actuator: Description and Operation
SYSTEM OPERATION
In the power lock and Remote Keyless Entry (RKE) systems, the door latch lock mechanisms can
be actuated by a reversible electric motor. A power lock motor module is secured to the bottom of
the door latch mounted within each front door. A power lock motor is integral to the latches used on
dual side or rear doors. A separate power lock motor with a connecting link is used to actuate the
latch in the sliding side or single rear door.
The power lock motor direction is controlled by the battery and ground feeds from the power lock
and unlock relays. The power lock and unlock relays are integral to the power lock and Remote
Keyless Entry (RKE) module, or the Central Timer Module (CTM).
The power door lock motors cannot be repaired and, if faulty or damaged, they must be replaced.
On dual side or rear doors the entire door latch unit must be replaced. The front door, sliding side
door, and single rear door power lock motors are serviced separately.

Power Door Lock Actuator: Testing and Inspection
Before you proceed with this diagnosis, confirm proper power lock switch, power lock and Remote
Keyless Entry (RKE) module or Central Timer Module (CTM), and power lock switch output circuit
operation. See Power Lock Switch, and Power Lock and Remote Keyless Entry Module or Central
Timer Module in the Diagnosis. Remember, the module circuitry controls the output to each of the
power lock motors.
1. Check each power lock motor for correct operation while moving the power lock switch to both
the Lock and Unlock positions. If all of the power
lock motors are inoperative, go to Step 3. If one power lock motor is inoperative, go to Step 4.
2. If all of the power lock motors are inoperative, the problem may be caused by one shorted motor.
Unplugging a shorted power lock motor from the
power lock circuit will allow the good power lock motors to operate. Unplug each power lock motor
wire harness connector, one at a time, and recheck both the lock and unlock functions by operating
the power lock switch. If all of the power lock motors are still inoperative after the above test, check
for a short or open circuit between the power lock motors and the power lock and RKE module or
the CTM. If unplugging one power lock motor causes the other motor to become functional, go to
Step 4 to test the unplugged motor.
3. Once it is determined which power lock motor is inoperative, that motor can be tested as follows.
Unplug the wire harness connector at the
inoperative power lock motor. Apply 12 volts to the motor terminals to check its operation in one
direction. Reverse the polarity to check the operation in the other direction. If OK, repair the short
or open circuits between the power lock motor and the power lock and RKE module or the CTM as
required. If not OK, replace the faulty power lock motor.

Dodge Workshop Manuals > Body and Frame > Seats > Power Seat Motor > Component Information > Description and
Operation
Power Seat Motor: Description and Operation
SYSTEM OPERATION
Power Seat Adjuster And Motors There are three reversible motors that operate the power seat
adjuster. The motors are connected to worm-drive gearboxes that move the seat adjuster through a
combination of screw-type drive units.
The front and rear of a seat are operated by different motors. They can be raised or lowered
independently of each other. When the center seat switch is pushed to the Up or Down position,
both the front and rear motors operate in unison, moving the entire seat up or down. The
forward-rearward motor is operated by pushing the center seat switch to the Forward or Rearward
position.
When a switch is actuated, a battery feed and a ground path are applied through the switch
contacts to the motor(s). The motor(s) and drives operate to move the seat in the selected direction
until the switch is released, or until the travel limit of the power seat adjuster is reached. When the
switch is moved in the opposite direction, the battery feed and ground path to the motor(s) are
reversed through the switch contacts. This causes the motor to run in the opposite direction.
Each motor contains a self-resetting circuit breaker to protect it from overload. Consecutive or
frequent resetting of the circuit breakers must not be allowed to continue, or the motors may be
damaged. Make the necessary repairs.
The power seat adjuster and motors cannot be repaired, and are serviced only as a complete unit.
If any component in this unit is faulty or damaged, the entire power seat adjuster and motors
assembly must be replaced.

Power Seat Motor: Testing and Inspection
Operate the power seat switch to move all three seat motors in each direction. The seat should
move in each of the selected directions. If the power seat adjuster fails to operate in only one
direction, move the adjuster a short distance in the opposite direction and test again to be certain
that the adjuster is not at its travel limit. If the power seat adjuster still fails to operate in only one
direction, see Power Seat Switch in the Diagnosis and Testing. If the power seat adjuster fails to
operate in more than one direction, proceed as follows:
1. Test the circuit breaker in the junction block as described. If OK, Step 3. If not OK, replace the
faulty circuit breaker. 2. Remove the power seat switch from the seat. Check for battery voltage at
the fused B(+) circuit cavity of the power seat switch wire harness
connector. If OK, go to Step 4. If not OK, repair the open circuit to the junction block as required.
3. Check for continuity between the ground circuit cavity of the power seat switch wire harness
connector and a good ground. There should be
continuity If OK, go to Step 5. If not OK, repair the open circuit to ground as required.
4. Test the power seat switch as described. If the switch tests OK, check the wire harness for the
inoperative power seat motor(s) between the power
seat switch and the motor for shorts or opens. If the circuits check OK, replace the faulty power
seat adjuster and motors assembly. If the circuits are not OK, repair the wire harness as required.

Repair Procedure
This bulletin involves locating points of water entry around the cargo doors and sealing the areas
around the weatherstrips or replacing the weatherstrips on the side and/or rear dual cargo doors.
FIRST CLOSING CARGO DOOR (LEFT DOOR - SIDE AND/OR REAR)

Page 5957
1. Inspect the cavity (Figure 1) on the upper inboard corner of the molded detail and top caliper
latch for a small gap. This condition can leak water into the door and/or past the weatherstrip into
the vehicle interior. If a gap is found, clean the area in and around the cavity then, seal the gap with
Mopar Silicone Rubber Adhesive Sealant p/n 04318025.
NOTE:
ALLOW THE SEALANT TO CURE FOR AT LEAST 30 MINUTES BEFORE PERFORMING A
VERIFICATION WATER TEST.
2. Inspect the front lower corner of the weatherstrip seal (Figure 1) to verify seal retention. The seal
is held in place by a retainer. If the retainer is missing, replace it with a new retainer p/n 03759944
or the weatherstrip seal can be secured to the door inner panel with Mopar Weatherstrip Adhesive
p/n 04773774.
3. Any water that may leak into the door will exit out the door through a drain located in the lower
front corner of the door. The weatherstrip seal has a small hole in the seal to allow the water exiting
out of the door drain to pass through the weatherstrip seal. Inspect the drain hole of the
weatherstrip seal for a clear path from the door drain to the bottom of the seal. If the drain hole in
the seal is restricted, open the hole up using a sharp object.
SECOND CLOSING CARGO DOOR (RIGHT SIDE DOOR - SIDE AND/OR REAR)
1. Inspect the weatherstrip seal in the area where the seal passes over the middle and upper
inboard character lines for a gap (Figure 2). A gap at the character lines may allow water to enter
behind the seal and travel down the interior side of the seal and into the interior of the vehicle at the
bottom of the door. If a gap is found, clean the area around the gap then, seal the gap with Mopar
Silicone Rubber Adhesive Sealant p/n 04318025.
NOTE:
ALLOW THE SEALANT TO CURE FOR AT LEAST 30 MINUTES BEFORE PERFORMING A
VERIFICATION WATER TEST.

Page 5958
2. Inspect the upper portion of the weatherstrip for a seal lip that may be bent over upon door
closing (Figure 2). If the upper portion of the weatherstrip seal is bent over, replace the
weatherstrip seal with p/n 55135270AB if the condition occurs on the side cargo door or p/n
55135271AB if the condition occurs on the rear cargo door. Refer to the appropriate Ram Van
Service Manual Group 23 for information regarding cargo door weatherstrip seal service.
NOTE:
VERIFY THAT THE LIP OF THE NEW WEATHERSTRIP SEAL DOES NOT BEND OVER WHEN
THE DOOR CLOSES. TRIM ANY EXCESS MATERIAL OFF THE LIP OF THE SEAL TO ENSURE
THAT IT WILL NOT BEND OVER WHEN THE DOOR CLOSES.
3. Inspect the weatherstrip seal at the rear lower corner (Figure 2) of the door for a seal that
squeezes out when the door closes. Use a foam stuffer glued to the hollow cavity behind the seal
to repair the condition. The foam stuffer will allow the seal to retain its form. The foam stuffer
should be made from a piece of 1/2 in. thick loose density foam such as 3M p/n 62385 Open Cell
Foam Tape and glued with Mopar Weatherstrip Adhesive p/n 04773774.
ALL CARGO DOORS
1. Inspect the weatherstrip seal at joints between the extruded bulb of the weatherstrip and the
molded detail for wrinkles or other surface irregularities. Replace any weatherstrip seal if wrinkles
or irregularities are found. Refer to the appropriate Ram Van Service Manual Group 23 for
information regarding cargo door weatherstrip seal service. Once the seal has been replaced,
verify that the sealing area of the new seal is smooth.
2. Inspect the backside of the weatherstrip seal at the header of the door (Figures 1 and 2) for a
water leakpath. Either seal the backside of the weatherstrip with Mopar Silicone Rubber Adhesive
Sealant p/n 04318025 or high/medium density foam tape 2-3 mm thick (such as 3M p/n 06375 or
equivalent), cut to 12 mm wide X 630 mm long. If foam tape is used, make sure the ends of the
foam are tapered so that there is no gaps created from the application of the foam tape.
NOTE:
ALLOW THE SEALANT TO CURE FOR AT LEAST 30 MINUTES BEFORE PERFORMING A
VERIFICATION WATER TEST.

Technical Service Bulletins for Weatherstrip: > 23-43-98 > Sep > 98 > Dual Cargo Door - Water Leak Diagnostic/Repair
Procedure > Page 5964
1. Inspect the cavity (Figure 1) on the upper inboard corner of the molded detail and top caliper
latch for a small gap. This condition can leak water into the door and/or past the weatherstrip into
the vehicle interior. If a gap is found, clean the area in and around the cavity then, seal the gap with
Mopar Silicone Rubber Adhesive Sealant p/n 04318025.
NOTE:
ALLOW THE SEALANT TO CURE FOR AT LEAST 30 MINUTES BEFORE PERFORMING A
VERIFICATION WATER TEST.
2. Inspect the front lower corner of the weatherstrip seal (Figure 1) to verify seal retention. The seal
is held in place by a retainer. If the retainer is missing, replace it with a new retainer p/n 03759944
or the weatherstrip seal can be secured to the door inner panel with Mopar Weatherstrip Adhesive
p/n 04773774.
3. Any water that may leak into the door will exit out the door through a drain located in the lower
front corner of the door. The weatherstrip seal has a small hole in the seal to allow the water exiting
out of the door drain to pass through the weatherstrip seal. Inspect the drain hole of the
weatherstrip seal for a clear path from the door drain to the bottom of the seal. If the drain hole in
the seal is restricted, open the hole up using a sharp object.
SECOND CLOSING CARGO DOOR (RIGHT SIDE DOOR - SIDE AND/OR REAR)
1. Inspect the weatherstrip seal in the area where the seal passes over the middle and upper
inboard character lines for a gap (Figure 2). A gap at the character lines may allow water to enter
behind the seal and travel down the interior side of the seal and into the interior of the vehicle at the
bottom of the door. If a gap is found, clean the area around the gap then, seal the gap with Mopar
Silicone Rubber Adhesive Sealant p/n 04318025.
NOTE:
ALLOW THE SEALANT TO CURE FOR AT LEAST 30 MINUTES BEFORE PERFORMING A
VERIFICATION WATER TEST.

Procedure > Page 5965
2. Inspect the upper portion of the weatherstrip for a seal lip that may be bent over upon door
closing (Figure 2). If the upper portion of the weatherstrip seal is bent over, replace the
weatherstrip seal with p/n 55135270AB if the condition occurs on the side cargo door or p/n
55135271AB if the condition occurs on the rear cargo door. Refer to the appropriate Ram Van
Service Manual Group 23 for information regarding cargo door weatherstrip seal service.
NOTE:
VERIFY THAT THE LIP OF THE NEW WEATHERSTRIP SEAL DOES NOT BEND OVER WHEN
THE DOOR CLOSES. TRIM ANY EXCESS MATERIAL OFF THE LIP OF THE SEAL TO ENSURE
THAT IT WILL NOT BEND OVER WHEN THE DOOR CLOSES.
3. Inspect the weatherstrip seal at the rear lower corner (Figure 2) of the door for a seal that
squeezes out when the door closes. Use a foam stuffer glued to the hollow cavity behind the seal
to repair the condition. The foam stuffer will allow the seal to retain its form. The foam stuffer
should be made from a piece of 1/2 in. thick loose density foam such as 3M p/n 62385 Open Cell
Foam Tape and glued with Mopar Weatherstrip Adhesive p/n 04773774.
ALL CARGO DOORS
1. Inspect the weatherstrip seal at joints between the extruded bulb of the weatherstrip and the
molded detail for wrinkles or other surface irregularities. Replace any weatherstrip seal if wrinkles
or irregularities are found. Refer to the appropriate Ram Van Service Manual Group 23 for
information regarding cargo door weatherstrip seal service. Once the seal has been replaced,
verify that the sealing area of the new seal is smooth.
2. Inspect the backside of the weatherstrip seal at the header of the door (Figures 1 and 2) for a
water leakpath. Either seal the backside of the weatherstrip with Mopar Silicone Rubber Adhesive
Sealant p/n 04318025 or high/medium density foam tape 2-3 mm thick (such as 3M p/n 06375 or
equivalent), cut to 12 mm wide X 630 mm long. If foam tape is used, make sure the ends of the
foam are tapered so that there is no gaps created from the application of the foam tape.
NOTE:
ALLOW THE SEALANT TO CURE FOR AT LEAST 30 MINUTES BEFORE PERFORMING A
VERIFICATION WATER TEST.

Cruise Control Switch: Description and Operation
SYSTEM OPERATION
Two separate speed control switch modules are mounted on the steering wheel to the left and right
side of the driver's airbag module. Within the two switch modules, five momentary contact
switches, supporting seven different speed control functions are used. The outputs from these
switches are filtered into one input. The Powertrain Control Module (PCM) determines which output
has been applied through resistive multiplexing. The input circuit voltage is measured by the PCM
to determine which switch function has been selected.
A speed control indicator lamp, located on the instrument panel cluster is energized by the PCM via
the CCD Bus. This occurs when speed control system power has been turned ON, and the engine
is running.
The two switch modules are labeled: ON/OFF, SET, RESUME/ACCEL, CANCEL and COAST.

Description and Operation > General Information
ABS Light: Description and Operation General Information
SYSTEM OPERATION
The Anti-Lock Brake System (ABS)lamp gives an indication when the ABS system is faulty or
inoperative. The lamp is controlled by the instrument cluster circuitry based upon messages
received from the Controller Anti-lock Brake (CAB) on the Chrysler Collision Detection (CCD) data
bus. The lamp is turned on by the CAB for about two seconds when the ignition switch is turned to
the On position as a bulb test.
After the bulb test, the CAB turns the lamp on or off based upon the results of the ABS self-tests.
The CAB continually monitors the ABS circuits and sensors to decide whether the system is in
good operating condition. The CAB then sends the proper messages to the instrument cluster on
the CCD data bus to turn the lamp on or off. If the CAB turns the lamp on after the bulb test, it
indicates that the CAB has detected a system malfunction and/or that the ABS system has become
inoperative. If only the amber ABS lamp is illuminated, and the red brake warning lamp remains off,
the base brake system will operate normally.
Each time the instrument cluster circuitry receives a lamp-on message from the CAB, it will light the
lamp for the duration of the ABS malfunction. The CAB will also flash this lamp during the
diagnostic mode, unless a hard fault is present. If a hard fault is present, the ABS lamp will
illuminate without flashing.

The amber ABS warning lamp is located in the instrument cluster. The lamp illuminates at start-up
to perform a self check. The lamp goes out when the self check program determines the system is
operating normal. If an ABS component exhibits a fault the Controller Antilock Brake (CAB) will
illuminate the lamp and register a trouble code in the microprocessor. The lamp is controlled by the
CAB. The CAB controls the lamp sending a message to the instrument cluster.

If the ABS lamp fails to light when the ignition switch is turned to the On position, replace the ABS
lamp bulb with a known good unit. If the ABS lamp still fails to operate, diagnosis of the ABS
system and the Chrysler Collision Detection (CCD) data bus should be performed with a DRB scan
tool as described in the proper Diagnostic Procedures. For further diagnosis of the ABS lamp and
the instrument cluster circuitry, see Instrument Cluster in the Diagnosis and Testing.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.
- ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE
CLOTHING.

Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Audible Warning Device: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Audible Warning Device: Description and Operation System Operation
SYSTEM OPERATION
Central Timer Module A Central Timer Module (CTM) is used on this vehicle when it is equipped
with the optional Vehicle Theft Security System (VTSS). In addition to serving as the security
system module, the CTM combines the functions of a chime/buzzer module, an intermittent wipe
module, an illuminated entry module, and a Remote Keyless Entry (RKE) module in a single unit.
The CTM is also able to control and integrate many of the additional electronic functions and
features included on models with this option. The CTM contains a central processing unit and
interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus
network.
The CCD data bus network allows the sharing of sensor information. This helps to reduce wire
harness complexity, reduce internal controller hardware, and reduce component sensor current
loads. At the same time, this system provides increased reliability, enhanced diagnostics, and
allows the addition of many new feature capabilities.
Intermittent wipe, wipe-after-wash, and speed sensitive intermittent wipe are some of the features
that the CTM supports. The intermittent wipe relay is one of the outputs that the CTM can control.
The CTM is programmed to energize or de-energize the intermittent wipe relay in response to
certain inputs from the windshield wiper and washer switches and from the windshield wiper motor
park switch.
For the speed sensitive intermittent wipe feature, the CTM also uses vehicle speed messages,
which are received on the CCD data bus from the Powertrain Control Module (PCM).
The CTM is mounted under the instrument panel, to the inboard side of the left center instrument
panel support. Refer to Instrument Panel, Gauges and Warning Indicators/Instrument
Panel/Central Timer Module Replacement.
For diagnosis of the CTM or the CCD data bus, a DRB scan tool and the proper Diagnostic
procedures manual are recommended. The CTM cannot be repaired and, if faulty or damaged, it
must be replaced.

Audible Warning Device: Description and Operation Chime System Operation
The chime system is built into the CTM. The system also supports an external chime request from
the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM
for gauge problems and tell tale warnings. The CTM chime functions will have priority over the MIC
chime requests. There are two chime rates, Low; 50 chimes per minute for reminders and High;
180 chimes per minute for serious conditions that require immediate attention. The high rate chime
sounds when the key is left in the ignition and the driver door is open or the headlights are left on.
The low rate chime sounds for any of the other conditions. There is a variable rate feature that
allows the chime to sound continuously for the key-in, and headlamp warning; as long as the
driver's door is open. The seat belt warning chime is activated for 4 to 6 seconds, and all other
chime conditions will activate the chime once at the same time the warning light on the cluster is
illuminated.
The chime will sound for the following conditions:
High Rate
- Key in Warning-ignition off, key in ignition, driver's door open
- Ignition off, headlamps on, driver's door open
Low Rate
- Seat belt warning-6 seconds after key on (6 to 8 chimes) or until seatbelt is buckled
- Airbag lamp illuminated (3 times after prove-out)
- ABS lamp illuminated (2 chimes after prove-out if equipped)
- Check engine lamp illuminated (2 chimes after prove-out)
- Check gauges lamp illuminated (2 chimes)
- Engine Temp-High-when gauge enters red zone (2 chimes)
- Low fuel - when fuel level reaches 1/8 tank (2 chimes)
- Low washer fluid (2 chimes)
- Transmission Temperature High (2 chimes)
If the ignition switch is turned to the run/start position and the driver's door is closed, then opened,
the warning chime is defeated. This allows the doors to be open without the warning chime
constantly sounding. The CTM stays in this mode until the ignition switch is turned to the "off"
position, then normal function will be restored.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Audible Warning Device Control Module: Description and Operation
SYSTEM OPERATION
A Central Timer Module (CTM) is used on this vehicle when it is equipped with the optional Vehicle
Theft Security System (VTSS). In addition to serving as the security system module, the CTM
combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated
entry module, and a Remote Keyless Entry (RKE) module in a single unit.
The CTM is also able to control and integrate many of the additional electronic functions and
features included on models with this option. The CTM contains a central processing unit and
interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus
network. The CCD data bus network allows the sharing of sensor information. This helps to reduce
wire harness complexity, reduce internal controller hardware, and reduce component sensor
current loads. At the same time, this system provides increased reliability, enhanced diagnostics,
and allows the addition of many new feature capabilities.
The horn relay is one of the outputs that the CTM can control. The CTM is programmed to energize
or de-energize the horn relay in response to certain inputs from the Vehicle Theft Security System
(VTSS) and the Remote Keyless Entry (RKE) system. Refer to Body and Frame/Locks/Power
Locks Systems for more information on the RKE system. Refer to Accessories and Optional
Equipment/Antitheft and Alarm Systems/Vehicle Theft/Security Systems for more information on
the VTSS.
The CTM is mounted under the instrument panel, to the inboard side of the left center instrument
panel support. Refer to Instrument Panel, Gauges and Warning Indicators/Instrument
Panel/Central Timer Module Replacement
For diagnosis of the CTM or the CCD data bus, a DRB scan tool and the proper Diagnostic
Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be
replaced.
The CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless
Entry (RKE) systems. The CTM receives hard wired inputs from the power lock switches, CCD
message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and
coded radio frequency inputs from the RKE transmitters. In response to those and many other
inputs, the internal programming of the CTM sends the proper outputs to control the power lock
motors, the headlamp and horn relays, and the courtesy lamps.
The RKE receiver within the CTM has a memory function to retain the vehicle access codes of at
least one, but no more than four RKE transmitters. The receiver is designed to retain the
transmitter codes in memory, even if the battery is disconnected.
Some of the features and functions of the power lock, illuminated entry and RKE systems made
possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a
power door lock switch if the key is in the ignition and/or the headlamps are on. However, the locks
can still be operated manually, with a key, or energized with the REE transmitter.
- A delay lock feature. With the delay lock feature, if a side or rear door is still open when a lock
request is received by the CTM, the module will automatically cycle all of the power lock motors to
lock five seconds after the doors are closed.
- An enhanced accident response feature will unlock all doors, then prevent the power door lock
system from locking the doors for a predetermined time interval, after receiving a CCD message
from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature
will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if
the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course,
these responses are dependent upon functional battery power and wiring circuitry following the
impact.
- Rolling door locks is a programmable feature of the power lock system. This feature will
automatically lock all of the doors and the liftgate after the vehicle reaches a speed of about 24
kilometers-per- hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is
opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour).
- A programmable feature of the RKE system is the enabling or disabling of the horn chirp following
activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the
horn chirp duration (twenty or forty milliseconds) can be selected.
The CTM is mounted under the instrument panel, to the inboard side of the left center instrument
panel support. Refer to Central Timer Module Replacement.
The programmable features of the CTM can be enabled or disabled using the DRB scan tool as
described in the proper Diagnostic Procedures. For diagnosis of the CTM or the CCD data bus, a
DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be
repaired and, if faulty or damaged, it must be replaced.

hardware, and reduce component sensor current loads. At the same time, this system provides
increased reliability, enhanced diagnostics, and allows the addition of many new feature
capabilities.
One of the features that the CTM supports and controls is the Vehicle Theft Security System
(VTSS). In the VTSS, the CTM receives hard--wired inputs from the door ajar, front door lock
cylinder, and ignition switches. The programming in the CTM allows it to process the information
from these inputs and send control outputs to energize or de-energize the headlamp (or security)
relay, horn relay; and the security lamp. The CTM also sends CCD data bus messages to the
Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS.
The CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry
(RKE) systems, which are integrated into the arming, disarming, and triggering function; of the
VTSS.
The CTM is mounted under the instrument panel, to the inboard side of the left center instrument
panel support. Refer to Instrument Panel, Gauges and Warning Indicators/Audible Warning Device
Control Module/

Brake Warning Indicator: Description and Operation General Information
SYSTEM OPERATION
The brake warning lamp gives an indication when the parking brake is applied, when the pressures
in the two halves of the split brake hydraulic system are unequal, if the Anti-lock Brake System
(ABS) lamp has failed and an ABS fault occurs, and during ABS diagnostics. The lamp is turned on
by the instrument cluster circuitry for about two seconds when the ignition switch is moved to the
Start position as a bulb test. After the bulb test, the lamp is controlled by a hard wired input from
the parking brake switch and/or by the instrument cluster circuitry based upon messages received
from the Controller Anti-lock Brake (CAB) on the Chrysler Collision Detection (CCD) data bus.
The CAB turns the lamp on or off based upon the results of the ABS self-tests. The CAB
continually monitors the ABS circuits and sensors, including the brake warning switch and the ABS
lamp, to decide whether the system is in good operating condition. The CAB then sends the proper
messages to the instrument cluster on the CCD data bus to turn the lamp on or off. If the CAB turns
the lamp on after the bulb test, it indicates that the CAB has detected a system malfunction.
The parking brake switch is hard wired to the instrument cluster and closes to ground when the
parking brake is applied. The brake warning switch is hard wired to the CAB and closes to ground
when it senses unequal hydraulic pressures in the two halves of the split brake hydraulic system,
possibly due to low brake fluid level or brake fluid leakage.
After the bulb test, if the red brake warning lamp remains illuminated with the parking brake
released, the base brake system may not be operational. The vehicle should never be operated
while the red brake warning lamp is illuminated.

Brake Warning Indicator: Description and Operation Brake Warning Lamp Description
The red brake warning lamp is used to alert the driver of a hydraulic fault or that the parking brake
is applied. For the RWAL system, the red brake warning lamp also is used to alerts the driver of a
problem with the RWAL system.
The brake warning lamp illuminates when a message is sent over the bus to the cluster to
illuminate the bulb. A ground for the bulb is provided when:
- The brakes are applied and the park brake switch is actuated.
- A hydraulic fault has occurred and the pressure differential switch is actuated.
- A RWAL fault has occurred.

Check Gauges Lamp: Description and Operation
SYSTEM OPERATION
The check gauges lamp gives an indication when certain gauges reflect a condition requiring
immediate attention. The lamp is turned on by the instrument cluster circuitry for about three
seconds after the ignition switch is turned to the On position as a bulb test. After the bulb test, the
lamp is controlled by the instrument cluster circuitry based upon gauge data messages received
from the Powertrain Control Module (PCM) on the Chrysler Collision Detection (CCD) data bus.
The PCM uses several inputs to decide what gauge data messages are required. The PCM then
sends the proper message to the instrument cluster on the CCD data bus. When the instrument
cluster circuitry receives a gauge data message that requires the check gauges lamp to be turned
on, it also sends a chime tone request to the Central Timer Module (CTM).
The gauge data messages for which the instrument cluster is programmed to turn on the check
gauges lamp are: Engine coolant temperature is high
- Engine oil pressure is low
- System voltage is high or low.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connector.
Component Identification
Component connectors are identified by the component name instead of a number.
Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Fasteners

Information > Diagrams > Diagram Information and Instructions > Page 6107
Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.

junction block, and are used to protect such items as: power door lock motors, power windows, and
various engine solenoids.
Positive Temperature Coefficient Symbol
A special symbol is used to identify these in the wiring diagrams.
Section Identification
Wiring Diagram Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Cigarette Lighter: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation
Troubleshooting Tests
Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the
circuit. Also refer to Troubleshooting Wiring Problems section.
Testing For Voltage
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of
the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check
voltage. Refer to the
appropriate test procedure.

Testing For Continuity
Testing For Continuity
1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of
the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of
the circuit being tested. Low or no resistance means good continuity.
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the
test light glows, there is a short-to-ground in that general area of the wiring harness.
Testing For A Short-to-ground On Fuses Powering Several Loads
1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace
the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the
battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the
circuit with the short-to-ground has been isolated.
Testing For Voltage Drop
Testing For Voltage Drop
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2.
Connect the other lead of the voltmeter to the other side of the switch or component.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Cigarette Lighter: Description and Operation
SYSTEM OPERATION
A cigar lighter is available equipment on this model. The cigar lighter is installed in the instrument
panel accessory switch plate, which is located near the center of the instrument panel, inboard of
the radio. The cigar lighter base is secured by a clamp on the back of the instrument panel
accessory switch plate.
The cigar lighter consists of two major components: a knob and heating element unit, and the cigar
lighter base or receptacle shell. The receptacle shell is connected to ground, and an insulated
contact in the bottom of the shell is connected to battery current. The cigar lighter receives battery
voltage from a fuse in the junction block only when the ignition switch is in the Accessory or On
positions.
The knob and heating element are encased within a spring-loaded housing, which also features a
sliding protective heat shield. When the knob and heating dement are inserted in the receptacle
shell, the heating element resistor coil is grounded through its housing to the receptacle shell. If the
cigar lighter knob is pushed inward, the heat shield slides up toward the knob exposing the heating
dement, and the heating element extends from the housing toward the insulated contact in the
bottom of the receptacle shell.
Two small spring-clip retainers are located on either side of the insulated contact inside the bottom
of the receptacle shell. These clips engage and hold the heating element against the insulated
contact long enough for the resistor coil to heat up. When the heating element is engaged with the
contact, battery current can flow through the resistor coil to ground, causing the resistor coil to
heat.
When the resistor coil becomes sufficiently heated, excess heat radiates from the heating element
causing the spring-clips to expand. Once the spring-clips expand far enough to release the heating
element, the spring-loaded housing forces the knob and heating element to pop back outward to
their relaxed position. When the cigar lighter knob and element are pulled out of the receptacle
shell, the protective heat shield slides downward on the housing so that the heating element is
recessed and shielded around its circumference for safety.
The cigar lighter knob and heating element unit, and the cigar lighter receptacle unit are available
for service. These components cannot be repaired and, if faulty or damaged, they must be
replaced.

Cruise Control Indicator Lamp: Description and Operation
SYSTEM OPERATION
The cruise-on indicator lamp gives an indication when the vehicle speed control system is turned
on even when the system is not currently engaged. The lamp is turned on by the instrument cluster
circuitry for about two seconds when the ignition switch is turned to the On position as a bulb test.
After the bulb test, the lamp is controlled by the instrument cluster circuitry based upon messages
received from the Powertrain Control Module (PCM) on the Chrysler Collision Detection (CCD)
data bus.
The PCM uses an input from the analog resistor-multiplexed vehicle speed control switches in the
steering wheel to decide whether to turn the lamp on or off. The PCM then sends the proper
messages to the instrument cluster on the CCD data bus.

Description and Operation
Fuel Gauge: Description and Operation
SYSTEM OPERATION
The fuel gauge gives an indication of the level of fuel in the fuel tank. The instrument cluster
circuitry controls the gauge pointer position. The instrument cluster circuitry calculates the proper
gauge pointer position based upon fuel level messages received from the Powertrain Control
Module (PCM) on the Chrysler Collision Detection (CCD) data bus.
The PCM uses an input from the fuel gauge sending unit and internal programming to decide what
fuel level messages are required. The PCM then sends the proper messages to the instrument
cluster on the CCD data bus. If the PCM messages indicate that the fuel level is below one-eighth
of a full tank for more than ten seconds (60 seconds if the vehicle speed input is greater than zero
miles-per-hour), the instrument cluster circuitry turns on the low fuel warning lamp and sends a
chime tone request to the Central Timer Module (CTM).
The fuel gauge sending unit is mounted to the electric fuel pump module located inside the fuel
tank. The sending unit has a float attached to the end of a swing-arm. The float moves up or down
within the fuel tank as the fuel level changes. As the float moves, an electrical contact on the pivot
end of the swing-arm wipes across a resistor coil, which changes the internal electrical resistance
of the sending unit.

If the problem being diagnosed is related to fuel gauge accuracy, be certain to confirm that the
problem is with the gauge or sending unit and not with the fuel tank. Inspect the fuel tank for signs
of damage or distortion that could affect the sending unit performance before you proceed with fuel
gauge diagnosis.

Fuel Gauge Sender: Description and Operation
DESCRIPTION
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a vanable resistor (track). The resistor track is used to
send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for
OBD II emission requirements.
OPERATION
For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the
sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and
arm move down. This increases the sending unit resistance causing the fuel gauge to read empty.
After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus
circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading.
For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the
sending unit to the PCM to indicate fuel level. The purpose of this feature is to prevent the OBD II
system from recording/setting false misfire and fuel system monitor trouble codes. The feature is
activated if the fuel level in the tank is less than approximately 15 percent of its rated capacity. If
equipped with a Leak Detection Pump (EVAP system monitor), this feature will also be activated if
the fuel level in the tank is more than approximately 85 percent of its rated capacity.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge Sender > Component
Information > Technical Service Bulletins > Page 6150
Fuel Gauge Sender: Testing and Inspection
The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down,
electrical resistance will change. To test the gauge sending unit only, it must be removed from
vehicle. The unit is part of the fuel pump module. Refer to Fuel Pump Module Removal Installation
for procedures.
Measure the resistance across the sending unit terminals. With float in up position, resistance should be 20 ohms ± 6 ohms.
- With float in down position, resistance should be 220 ± 6 ohms.

Information > Description and Operation
Low Fuel Lamp/Indicator: Description and Operation
SYSTEM OPERATION
Low Fuel Warning Lamp The low fuel warning lamp gives an indication when the fuel level in the
fuel tank has fallen below about one-eighth of a full tank, as registered on the fuel gauge. The
instrument cluster circuitry lights the lamp for about two seconds when the ignition switch is turned
to the On position as a bulb test. After the bulb test, the instrument cluster circuitry controls the
lamp based upon fuel level and vehicle speed messages received from the Powertrain Control
Module (PCM) on the Chrysler Collision Detection (CCD) data bus.
The PCM uses inputs from the fuel gauge sending unit, the Controller Anti-lock Brake (CAB), and
internal programming to decide what messages are required. The PCM then sends the proper
messages to the instrument cluster on the CCD data bus.
If the PCM messages indicate that the fuel level is below one-eighth of a full tank for more than ten
seconds, and that the vehicle is not moving, the instrument cluster circuitry turns on the low fuel
warning lamp and sends a chime tone request to the Central Timer Module (CTM). To reduce the
effects of fuel sloshing, if the vehicle speed message indicates that the vehicle is moving, the fuel
level message must remain below one-eighth of a full tank for more than sixty seconds before the
lamp will be illuminated.
The fuel gauge sending unit is mounted to the electric fuel pump module inside the fuel tank. The
sending unit has a float attached to the end of a swing-arm. The float moves up or down within the
fuel tank as the fuel level changes. As the float moves an electrical contact on the pivot end of the
swing-arm wipes across a resistor coil, which changes the resistance of the sending unit.

Malfunction Indicator Lamp: Description and Operation
Data Link Connector
As a functional test, the MIL (check engine) illuminates at key-on before engine cranking.
Whenever the Powertrain Control Module (PCM) sets a Diagnostic Trouble Code (DTC) that affects
vehicle emissions, it illuminates the MIL. If a problem is detected, the PCM sends a message to the
instrument cluster to illuminate the lamp. The PCM illuminates the MIL only for DTC's that affect
vehicle emissions. There are some monitors that may take two consecutive trips, with a detected
fault, before the MIL is illuminated. The MIL stays on continuously when the PCM has entered a
Limp-In mode or identified a failed emission component. Also, the MIL either flashes or illuminates
continuously when the PCM detects active engine misfire.
Additionally, the PCM may reset (turn off) the MIL when one of the following occur:
^ PCM does not detect the malfunction for 3 consecutive trips (except misfire and Fuel system
Monitors).
^ PCM does not detect a malfunction while performing three successive engine misfire or fuel
system tests. The PCM performs these tests while the engine is operating within ± 375 RPM of and
within 10 % of the load of the operating condition at which the malfunction was first detected.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Odometer > Component Information >
Description and Operation
Odometer: Description and Operation
SYSTEM OPERATION
The odometer and the trip odometer share the same Liquid Crystal Display (LCD) on the
instrument cluster circuit board. Each gives an indication of the distance the vehicle has travelled.
However, by depressing the reset knob on the face of the instrument cluster, the display mode can
be switched from odometer to trip odometer. Depressing the reset knob for longer than two
seconds while in the trip odometer mode will reset the trip odometer to zero. The odometer and trip
odometer display values are based upon odometer and trip odometer messages received from the
Powertrain Control Module (PCM) on the Chrysler Collision Detection (CCD) data bus.
The PCM uses a speed pulse input received from the Controller Anti-lock Brake (CAB) and internal
programming to decide what vehicle speed and distance messages are required. The PCM then
sends the proper messages to the instrument cluster circuitry on the CCD data bus. The CAB uses
an input from the rear wheel speed sensor and internal programming, which includes a
programmable pinion factor to compensate for different axle gear ratios and tire sizes, to determine
what speed pulse output is required. The CAB then sends the proper speed pulse to the PCM on a
hard wired circuit.
The instrument cluster stores both the last odometer and last trip odometer distance messages it
receives from the PCM, and displays the proper value based upon ignition key-on and trip
odometer reset knob inputs. If the instrument cluster stops receiving distance messages from the
PCM during its current ignition key-on cycle, the odometer or trip odometer will display the last
distance value that was received. If the instrument cluster has not received any distance messages
from the PCM during its current ignition key-on cycle, the odometer or trip odometer display will
blink.
The rear wheel speed sensor is excited by an exciter ring on the differential case within the rear
axle housing. Incorrect tire size, incorrect axle ratio, an incorrect pinion factor, a faulty or improperly
installed rear wheel speed sensor, a faulty rear axle exciter ring, or a faulty CAB can each result in
inaccurate odometer readings. For diagnosis of the odometer and trip odometer inputs, a DRB
scan tool and the proper Diagnostic Procedures are recommended.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Gauge > Component
Information > Description and Operation
Oil Pressure Gauge: Description and Operation
SYSTEM OPERATION
The oil pressure gauge gives an indication of the engine oil pressure. The instrument cluster
circuitry controls the gauge pointer position. The instrument cluster circuitry calculates the proper
gauge pointer position based upon engine oil pressure messages received from the Powertrain
Control Module (PCM) on the Chrysler Collision Detection (CCD) data bus.
The PCM uses an input from the engine oil pressure sensor and internal programming to decide
what engine oil pressure messages are required. The PCM then sends the proper messages to the
instrument cluster on the CCD data bus. If the PCM messages indicate that oil pressure is too low,
the instrument cluster circuitry moves the gauge needle to the 0 PSI graduation on the gauge face,
turns on the Check Gauges lamp, and sends a chime tone request to the Central Timer Module
(CTM). If the PCM messages indicate that oil pressure is too high, the instrument cluster circuitry
moves the gauge needle to the 110 PSI graduation on the gauge face.
The engine oil pressure sensor is installed in a threaded hole that penetrates an oil passage of the
engine. The engine oil pressure sensor contains a flexible diaphragm and a variable resistor coil.
The diaphragm moves in response to changes in the engine oil pressure, which changes the
internal electrical resistance of the sensor.

Oil Pressure Gauge: Testing and Inspection
If the problem being diagnosed is related to oil pressure gauge accuracy, be certain to confirm that
the problem is with the gauge and not with the engine oiling system performance. The actual
engine oil pressure should be checked with a test gauge and compared to the instrument cluster oil
pressure gauge readings before you proceed with gauge diagnosis.

ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
NOTE: Increased oil pressure gauge needle activity may be noted with this instrument cluster than
with previous designs. This increased needle activity is due to changes that were made to the
instrument cluster software that are intended to make the gauge more responsive, and not due to
any problem with the engine oiling or oil pressure gauge systems. No attempt at service of these
systems should be made, unless the oil pressure gauge readings remain in the high end or the low
end of the normal range.
Diagnosis of the oil pressure sensor and circuit, the Chrysler Collision Detection (CCD) data bus,
and/or the Powertrain Control Module (PCM) should be performed with a DRB scan tool. For
further diagnosis of the oil pressure gauge and the instrument cluster circuitry, refer to Instrument
Panel/Testing and Inspection. See: Instrument Cluster / Carrier/Testing and Inspection

Overdrive Indicator Lamp: Description and Operation
SYSTEM OPERATION
The overdrive-off indicator lamp gives the driver an indication that the automatic transmission
overdrive has been locked out. The lamp is controlled by the Powertrain Control Module (PCM) on
a hard wired circuit to instrument cluster.
The PCM receives an input from the momentary overdrive lockout switch, which is located on the
end of the automatic transmission gearshift selector lever. The PCM uses the overdrive lockout
switch input, along with numerous other sensor inputs and its internal programming to decide
whether the over-drive-off indicator lamp should be on or off. The PCM then turns the lamp on or
off by controlling the ground path for the lamp control circuit.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Connector Identification
Multiple connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to
indicate this. When handling any component with this symbol, comply with the following procedures
to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into
the component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part, especially after sliding across a seat,
sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.

Shock Tower To Spring Minimum Clearance Area
CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal
fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes
can be drilled into the front strut tower in the area shown in for the installation of any metal
fasteners into the strut tower.
Because of the minimum clearance in this area , installation of metal fasteners could damage the
coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost
or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts
catalog.
Fuses
CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct
amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical
overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.

Audible Warning Device Control Module: Diagnostic Aids
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked in
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt and moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation covering.
- Wiring broken inside of the insulation

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Audible Warning Device Control Module: Description and Operation
SYSTEM OPERATION
A Central Timer Module (CTM) is used on this vehicle when it is equipped with the optional Vehicle
Theft Security System (VTSS). In addition to serving as the security system module, the CTM
combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated
entry module, and a Remote Keyless Entry (RKE) module in a single unit.
The CTM is also able to control and integrate many of the additional electronic functions and
features included on models with this option. The CTM contains a central processing unit and
interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus
network. The CCD data bus network allows the sharing of sensor information. This helps to reduce
wire harness complexity, reduce internal controller hardware, and reduce component sensor
current loads. At the same time, this system provides increased reliability, enhanced diagnostics,
and allows the addition of many new feature capabilities.
The horn relay is one of the outputs that the CTM can control. The CTM is programmed to energize
or de-energize the horn relay in response to certain inputs from the Vehicle Theft Security System
(VTSS) and the Remote Keyless Entry (RKE) system. Refer to Body and Frame/Locks/Power
Locks Systems for more information on the RKE system. Refer to Accessories and Optional
Equipment/Antitheft and Alarm Systems/Vehicle Theft/Security Systems for more information on
the VTSS.
The CTM is mounted under the instrument panel, to the inboard side of the left center instrument
panel support. Refer to Instrument Panel, Gauges and Warning Indicators/Instrument
Panel/Central Timer Module Replacement
For diagnosis of the CTM or the CCD data bus, a DRB scan tool and the proper Diagnostic
Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be
replaced.
The CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless
Entry (RKE) systems. The CTM receives hard wired inputs from the power lock switches, CCD
message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and
coded radio frequency inputs from the RKE transmitters. In response to those and many other
inputs, the internal programming of the CTM sends the proper outputs to control the power lock
motors, the headlamp and horn relays, and the courtesy lamps.
The RKE receiver within the CTM has a memory function to retain the vehicle access codes of at
least one, but no more than four RKE transmitters. The receiver is designed to retain the
transmitter codes in memory, even if the battery is disconnected.
Some of the features and functions of the power lock, illuminated entry and RKE systems made
possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a
power door lock switch if the key is in the ignition and/or the headlamps are on. However, the locks
can still be operated manually, with a key, or energized with the REE transmitter.
- A delay lock feature. With the delay lock feature, if a side or rear door is still open when a lock
request is received by the CTM, the module will automatically cycle all of the power lock motors to
lock five seconds after the doors are closed.
- An enhanced accident response feature will unlock all doors, then prevent the power door lock
system from locking the doors for a predetermined time interval, after receiving a CCD message
from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature
will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if
the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course,
these responses are dependent upon functional battery power and wiring circuitry following the
impact.
- Rolling door locks is a programmable feature of the power lock system. This feature will
automatically lock all of the doors and the liftgate after the vehicle reaches a speed of about 24
kilometers-per- hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is
opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour).
- A programmable feature of the RKE system is the enabling or disabling of the horn chirp following
activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the
horn chirp duration (twenty or forty milliseconds) can be selected.
The CTM is mounted under the instrument panel, to the inboard side of the left center instrument
panel support. Refer to Central Timer Module Replacement.
The programmable features of the CTM can be enabled or disabled using the DRB scan tool as
described in the proper Diagnostic Procedures. For diagnosis of the CTM or the CCD data bus, a
DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be
repaired and, if faulty or damaged, it must be replaced.

hardware, and reduce component sensor current loads. At the same time, this system provides
increased reliability, enhanced diagnostics, and allows the addition of many new feature
capabilities.
One of the features that the CTM supports and controls is the Vehicle Theft Security System
(VTSS). In the VTSS, the CTM receives hard--wired inputs from the door ajar, front door lock
cylinder, and ignition switches. The programming in the CTM allows it to process the information
from these inputs and send control outputs to energize or de-energize the headlamp (or security)
relay, horn relay; and the security lamp. The CTM also sends CCD data bus messages to the
Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS.
The CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry
(RKE) systems, which are integrated into the arming, disarming, and triggering function; of the
VTSS.
The CTM is mounted under the instrument panel, to the inboard side of the left center instrument
panel support. Refer to Instrument Panel, Gauges and Warning Indicators/Audible Warning Device
Control Module/

Seat Belt Reminder Lamp: Description and Operation
SYSTEM OPERATION
The seat belt reminder lamp gives a visual reminder to the vehicle occupants to fasten their seat
belts. The lamp is turned on by the instrument cluster circuitry for about seven seconds when the
ignition switch is turned to the On position.
The instrument cluster also receives a hard wired input from the driver seat belt switch. However,
this input only affects the chime function and has no effect on the seat belt reminder lamp
operation. If the driver seat belt switch is closed (seat belt is not buckled), the instrument cluster will
send a chime request to the Central Timer Module (CTM) lasting the duration of the seat belt
reminder lamp illumination. The chime warning will stop when the driver seat belt switch is open
(seat belt is buckled).
The seat belt reminder lamp also serves as a backup for the airbag indicator lamp. About twenty
seconds after the ignition switch is turned to the On position, if an inoperative airbag indicator lamp
circuit was detected during the bulb test sequence, the instrument cluster circuitry will flash the seat
belt reminder lamp on and off for about thirty seconds. If the seat belt reminder lamp stays on after
flashing for thirty seconds, or comes on at any time other than about twenty seconds after the initial
ignition-on sequence, it indicates an airbag system fault has been detected and that the airbag
indicator lamp is inoperative.
Refer to Air Bags and Seat Belts/Air Bags for more information on the airbag system.

Seat Belt Reminder Lamp: Testing and Inspection
The diagnosis found here addresses an inoperative seat belt reminder lamp condition. If the lamp
comes on and flashes following its display function (about ten seconds after the ignition switch is
turned to the On position), it indicates an inoperative airbag indicator lamp. Refer to Restraint
Systems/Air Bag Systems/Testing and Inspection for additional testing procedures. See: Restraint
Systems/Air Bag Systems/Testing and Inspection
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
If the seat belt reminder lamp fails to light during its normal display function (about six seconds
after the ignition switch is turned to the On position), see Instrument Cluster in the Diagnosis and
Testing for further diagnosis. This lamp is completely controlled by the instrument cluster circuitry.
On models equipped with a Central Timer Module, the hard wired seat belt switch input to the
instrument cluster has no control over the seat belt reminder lamp function and is only used by the
instrument cluster circuitry as a reference for its chime request function.

Fuel Gauge Sender: Description and Operation
DESCRIPTION
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a vanable resistor (track). The resistor track is used to
send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for
OBD II emission requirements.
OPERATION
For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the
sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and
arm move down. This increases the sending unit resistance causing the fuel gauge to read empty.
After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus
circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading.
For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the
sending unit to the PCM to indicate fuel level. The purpose of this feature is to prevent the OBD II
system from recording/setting false misfire and fuel system monitor trouble codes. The feature is
activated if the fuel level in the tank is less than approximately 15 percent of its rated capacity. If
equipped with a Leak Detection Pump (EVAP system monitor), this feature will also be activated if
the fuel level in the tank is more than approximately 85 percent of its rated capacity.

Fuel Gauge Sender: Testing and Inspection
The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down,
electrical resistance will change. To test the gauge sending unit only, it must be removed from

Speedometer Head: Description and Operation
SYSTEM OPERATION
The speedometer gives an indication of the current vehicle speed. The instrument cluster circuitry
controls the gauge pointer position. The instrument cluster circuitry calculates the proper gauge
pointer position based upon vehicle speed messages received from the Powertrain Control Module
(PCM) on the Chrysler Collision Detection (CCD) data bus.
The PCM uses a speed pulse input received from the Controller Anti-lock Brake (CAB) and internal
programming to decide what vehicle speed and distance messages are required. The PCM then
sends the proper messages to the instrument cluster circuitry on the CCD data bus. The CAB uses
an input from the rear wheel speed sensor and internal programming, which includes a
programmable pinion factor to compensate for different axle gear ratios and tire sizes, to determine
what speed pulse output is required. The CAB then sends the proper speed pulse to the PCM on a
hard wired circuit.
The rear wheel speed sensor is excited by an exciter ring on the differential case within the rear
axle housing. Incorrect tire size, incorrect axle ratio, an incorrect pinion factor, a faulty or improperly
installed rear wheel speed sensor, a faulty rear axle exciter ring, or a faulty CAB can each result in
inaccurate speedometer readings. For diagnosis of the speedometer inputs, a DRB scan tool and
the proper Diagnostic Procedures are recommended.

Temperature Gauge: Description and Operation
SYSTEM OPERATION
The coolant temperature gauge gives an indication of the engine coolant temperature. The
instrument cluster circuitry controls the gauge pointer position. The instrument cluster circuitry
calculates the proper gauge pointer position based upon engine coolant temperature messages
received from the Powertrain Control Module (PCM) on the Chrysler Collision Detection (CCD)
data bus.
The PCM uses an input from the engine coolant temperature sensor and internal programming to
decide what engine coolant temperature messages are required. The PCM then sends the proper
messages to the instrument cluster on the CCD data bus.
If the PCM messages indicate that coolant temperature is too high, the instrument cluster circuitry
moves the gauge needle to the high end of the scale on the gauge face, turns on the Check
Gauges lamp, and sends a chime tone request to the Central Timer Module (CTM).
The engine coolant temperature sensor is installed in a threaded hole that penetrates a coolant
passage of the engine. It is a thermistor-type sensor that changes its internal resistance with
changes in engine coolant temperature.

Temperature Warning Lamp/Indicator: Description and Operation
SYSTEM OPERATION
Transmission Oil Temperature Warning Lamp The transmission oil temperature warning lamp gives
an indication when the Powertrain Control Module (PCM) has detected that the automatic
transmission oil is overheated. The lamp is controlled by the instrument cluster circuitry based upon
messages received from the PCM on the Chrysler Collision Detection (CCD) data bus. The PCM
sends lamp-on messages for about two seconds when the ignition switch is turned to the On
position as a bulb test.
Following the bulb test, the PCM uses an input from the automatic transmission oil temperature
sensor located within the transmission, along with its internal programming, to decide whether a
condition exists that requires the transmission oil temperature warning lamp to be turned on. The
PCM then sends the proper messages to the instrument cluster on the CCD data bus to turn the
lamp on or off. When the instrument cluster receives a message to turn the transmission oil
temperature warning lamp on, it also sends a chime tone request to the Central Timer Module
(CTM).

The primary function of the switch,is to turn on the stop lamps during braking. The switch is also
used to send signals to components that must know when the brakes are applied, such as the
Powertrain Control Module (PCM), which uses the signal to cancel speed control. The Controller
Antilock Brake (CAB) uses the brake switch signal to monitor brake pedal application. When the
switch contacts open (brakes applied), the CAB receives the brake applied signal. The CAB then
monitors the ABS system to anticipate the need for an ABS stop.

Hazard Warning Flasher: Description and Operation
SYSTEM OPERATION
The combination flasher is a smart relay that functions as both the turn signal system and hazard
warning system flasher. The combination flasher contains active electronic Integrated Circuitry (IC)
elements. This flasher is designed to handle the current flow requirements of the factory-installed
lighting. If supplemental lighting is added to the turn signal lamp circuits, such as when towing a
trailer with lights, the combination flasher will automatically try to compensate to keep the flash rate
the same.
While the combination flasher has a International Standards Organization (ISO)-type relay terminal
configuration or footprint, the internal circuitry is much different. The combination flasher does not
use standard 150-relay inputs or provide ISO-relay type outputs or functions. The combination
flasher should never be substituted for an ISO-relay or replaced with an ISO-relay, or else
component and vehicle damage may occur.
Combination Flasher - Typical
The combination flasher has five blade-type terminals intended for the following inputs and outputs:
Battery B+, Ignition B+, Ground, Turn Signal circuit, and Hazard Warning circuit. Constant battery
voltage and ground are supplied to the flasher so that it can perform the hazard warning function,
and ignition switched battery voltage is supplied for the turn signal function.
The IC within the combination flasher contains the logic that controls the flasher operation and the
flash rate. Pin 6 of the IC receives a sense voltage from the hazard warning portion of the
multi-function switch. When the hazard switch is turned on, the "hazard on sense" voltage will
become low due to the circuit being grounded through the turn signal bulbs. This low voltage sense
signals the IC to energize the flash control Positive-Negative-Positive (PNP) transistor at a
pre-calibrated flash rate or frequency Each time the PNP transistor energizes the hazard warning
circuit, the pin 6 "hazard on sense" voltage will become high and the IC signals the PNP transistor
to de-energize the circuit. This cycling will continue until the hazard warning switch is turned off.
Likewise, pin 8 of the IC receives a sense voltage from the turn signal portion of the multi-function
switch. When the left or right turn signal is turned on, the "turn signal on sense" voltage will become
low due to the circuit being grounded through the turn signal bulbs. This low voltage sense signals
the IC to energize the flash control PNP transistor at a precalibrated flash rate or frequency. Each
time the PNP transistor energizes the turn signal circuit, the pin 8 "turn signal on sense" voltage will
become high and the IC signals the PNP transistor to de-energize the circuit. This cycling will
continue until the right or left turn signal is turned off.
A special design feature of the combination flasher allows it to "sense" that a turn signal circuit or
bulb is not operating, and provide the driver an indication of the condition by flashing the remaining
bulbs in the affected circuit at a higher rate (120 flashes-per-minute or higher). Conventional
flashers either continue flashing at their typical rate (heavy-duty type), or discontinue flashing the
affected circuit entirely (standard-duty type). During turn signal operation, the combination flasher
IC compares normal battery voltage input on pin 2 with the shunt resistor voltage input on pin 7. If
the IC "senses" that the voltage difference between pin 2 and pin 7 is different than the
pre-calibrated value of the IC, it will increase the rate at which it signals the PNP transistor to
energize the pin 1 output. Thus, the inoperative half (left or right side) of the turn signal circuit will
flash faster.
Because of the active electronic elements within the combination flasher, it cannot be tested with
conventional automotive electrical test equipment. If the combination flasher is believed to be
faulty; test the turn signal and hazard warning system circuits as described. Then replace the
combination flasher with a known good unit to confirm system operation.
The combination flasher cannot be repaired and, if faulty or damaged, it must be replaced.

The horn relay is a International Standards Organization (ISO) micro-relay. The terminal
designations and functions are the same as a conventional ISO relay. However, the micro-relay
terminal orientation (or footprint) is different, current capacity is lower, and the relay case
dimensions are smaller than those of the conventional ISO relay.
The horn relay is a electromechanical device that switches battery current to the horn when the
horn switch grounds the relay coil. See Horn Relay in the Diagnosis and Testing for more
information.
The horn relay is located in the junction block, which is located on the driver side end of the
instrument panel in the passenger compaftment.
If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by
removing the horn relay from the junction block until further diagnosis is completed.

Brake Light Switch: Description and Operation Switch With RWAL System
The primary function of the switch,is to turn on the stop lamps during braking. The switch is also
used to send signals to components that must know when the brakes are applied, such as the
Powertrain Control Module (PCM), which uses the signal to cancel speed control. The Controller
Antilock Brake (CAB) uses the brake switch signal to monitor brake pedal application. When the
switch contacts open (brakes applied), the CAB receives the brake applied signal. The CAB then
monitors the ABS system to anticipate the need for an ABS stop.

Description and Operation
Turn Signal Flasher: Description and Operation
SYSTEM OPERATION
The combination flasher is a smart relay that functions as both the turn signal system and hazard
warning system flasher. The combination flasher contains active electronic Integrated Circuitry (IC)
elements. This flasher is designed to handle the current flow requirements of the factory-installed
lighting. If supplemental lighting is added to the turn signal lamp circuits, such as when towing a
trailer with lights, the combination flasher will automatically try to compensate to keep the flash rate
the same.
While the combination flasher has a International Standards Organization (ISO)-type relay terminal
configuration or footprint, the internal circuitry is much different. The combination flasher does not
use standard 150-relay inputs or provide ISO-relay type outputs or functions. The combination
flasher should never be substituted for an ISO-relay or replaced with an ISO-relay, or else
component and vehicle damage may occur.
Combination Flasher - Typical
The combination flasher has five blade-type terminals intended for the following inputs and outputs:
Battery B+, Ignition B+, Ground, Turn Signal circuit, and Hazard Warning circuit. Constant battery
voltage and ground are supplied to the flasher so that it can perform the hazard warning function,
and ignition switched battery voltage is supplied for the turn signal function.
The IC within the combination flasher contains the logic that controls the flasher operation and the
flash rate. Pin 6 of the IC receives a sense voltage from the hazard warning portion of the
multi-function switch. When the hazard switch is turned on, the "hazard on sense" voltage will
become low due to the circuit being grounded through the turn signal bulbs. This low voltage sense
signals the IC to energize the flash control Positive-Negative-Positive (PNP) transistor at a
pre-calibrated flash rate or frequency Each time the PNP transistor energizes the hazard warning
circuit, the pin 6 "hazard on sense" voltage will become high and the IC signals the PNP transistor
to de-energize the circuit. This cycling will continue until the hazard warning switch is turned off.
Likewise, pin 8 of the IC receives a sense voltage from the turn signal portion of the multi-function
switch. When the left or right turn signal is turned on, the "turn signal on sense" voltage will become
low due to the circuit being grounded through the turn signal bulbs. This low voltage sense signals
the IC to energize the flash control PNP transistor at a precalibrated flash rate or frequency. Each
time the PNP transistor energizes the turn signal circuit, the pin 8 "turn signal on sense" voltage will
become high and the IC signals the PNP transistor to de-energize the circuit. This cycling will
continue until the right or left turn signal is turned off.
A special design feature of the combination flasher allows it to "sense" that a turn signal circuit or
bulb is not operating, and provide the driver an indication of the condition by flashing the remaining
bulbs in the affected circuit at a higher rate (120 flashes-per-minute or higher). Conventional
flashers either continue flashing at their typical rate (heavy-duty type), or discontinue flashing the
affected circuit entirely (standard-duty type). During turn signal operation, the combination flasher
IC compares normal battery voltage input on pin 2 with the shunt resistor voltage input on pin 7. If
the IC "senses" that the voltage difference between pin 2 and pin 7 is different than the
pre-calibrated value of the IC, it will increase the rate at which it signals the PNP transistor to
energize the pin 1 output. Thus, the inoperative half (left or right side) of the turn signal circuit will
flash faster.
Because of the active electronic elements within the combination flasher, it cannot be tested with
conventional automotive electrical test equipment. If the combination flasher is believed to be
faulty; test the turn signal and hazard warning system circuits as described. Then replace the
combination flasher with a known good unit to confirm system operation.
The combination flasher cannot be repaired and, if faulty or damaged, it must be replaced.

Turn Signal Indicator: Description and Operation
SYSTEM OPERATION
The left and right turn signal indicator lamps give an indication when the turn signal circuits are
activated. The lamps are hard wired in the instrument cluster, and are completely controlled by the
turn signal and hazard warning (multi-function) switches.
The indicator lamps are grounded at all times and receive battery feed through the contacts of the
multi-function switch when the turn signal lever (multi-function switch stalk) or the hazard warning
button are actuated to their On positions. The instrument cluster circuitry does not perform a bulb
test of these lamps. Refer to Lighting and Horns/Turn Signal and Hazard Warning Systems for
more information.
The turn signal indicator lamps are located in the instrument duster. They flash with the exterior
turn signal lamps to give the driver a visual indication that a turn signal or the hazard warning
system is operating. Refer to Turn Signal Indicator Lamp in Instrument Panel Systems and Lighting
and Horns for diagnosis or service of these lamps.

Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.
In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is
important to understand all of their features and characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page.
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition.
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around a component indicates that the component being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.

Troubleshooting Tools
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit, there are several common tools necessary.
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black
lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking voltages in these circuits, use a meter with a 10 megohm or greater impedance.
- Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low
or no resistance in a circuit can mean good continuity or a shorted circuit.
CAUTION: Most of the electrical components used in today's vehicle are solid state. When
checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In
addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the
vehicle electrical system can cause damage to the equipment and provide false readings.
Probing Tool
- Probing Tools - These tools are used for probing terminals in connectors. Select the proper size
tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for non-factory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem.
2. Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the
problem most likely is occurring and where the
diagnosis will continue.
4. Isolate the problem area.
5. Repair the problem.
6. Verify proper operation. For this step check for proper operation of all items on the repaired
circuit. Refer to the wiring diagrams.

Heated Glass Element: Description and Operation
INTRODUCTION
An electrically heated rear window defogger is optional factory-installed equipment on this model,
when it is equipped with a single rear cargo door.
Rear Window Defogger System The rear window defogger system will only operate when the
ignition switch is in the On position. When the defogger switch is in the On position, an electric
heater grid on the rear window glass is energized. The electric heater grid produces heat to help
clear the rear window glass of ice, snow, or fog.
The defogger system is controlled by a momentary switch that is integral to the heater and air
conditioner control assembly, which is located below the radio in the instrument cluster bezel on
the instrument panel. An amber indicator lamp above the switch will light to indicate when the
defogger system is turned on. The heater and air conditioner control assembly also contains the
defogger system timer and logic circuitry, and an integral defogger relay.
The defogger system will be automatically turned off after a programmed time interval of about ten
minutes. After the initial time interval has expired, if the defogger switch is turned on again during
the same ignition cycle, the defogger system will automatically turn off after about five minutes.
The defogger system will automatically shut off if the ignition switch is turned to the Off position, or
it can be turned off manually by depressing the defogger switch again. Following are general
descriptions of the major components in the rear window defogger system. Refer to the owner's
manual in the vehicle glove box for more information on the features, use and operation of the rear
window defogger system.
SYSTEM OPERATION
Rear Glass Heating Grid The heated rear window glass has two electrically conductive vertical bus
bars and a series of horizontal grid lines made of a silver-ceramic material, which is baked on and
bonded to the inside surface of the glass. The grid lines and bus bars comprise a parallel electrical
circuit.
When the rear window defogger switch is placed in the On position, electrical current is directed to
the rear window grid lines through the bus bars. The grid lines heat the rear window to clear the
surface of fog or snow. Protection for the heating grid circuit is provided by a fuse in the Power
Distribution Center (PDC).
The grid lines and bus bars are highly resistant to abrasion. However, it is possible for an open
circuit to occur in an individual grid line, resulting in no current flow through the line.
The grid lines can be damaged or scraped off with sharp instruments. Care should be taken when
cleaning the glass or removing foreign materials, decals, or stickers from the glass. Normal glass
deaning solvents or hot water used with rags or toweling is recommended. A repair kit is available
to repair the grid lines and bus bars, or to reinstall the heated glass terminals.
Rear Window Defogger System Control The rear window defogger switch, rear window defogger
indicator lamp, rear window defogger mirror electronic timer/control/logic circuitry and rear window
defogger relay are all integral to the heater and air conditioner control assembly, which is located
below the radio in the instrument cluster bezel on the instrument panel. The momentary-type switch
provides a hard wired battery signal to the electronic circuitry each time it is depressed. An amber
rear window defogger indicator lamp above the rear window defogger switch lights to indicate when
the rear window defogger system is turned On.
The rear window defogger electronic timer/control/ logic circuitry responds to the swift input by
energizing or de-energizing the rear window defogger relay. Energizing the rear window defogger
relay provides electrical current to the rear glass heating grid.
The rear window defogger switch, rear window defogger indicator lamp, rear window defogger
electronic timer/control/logic circuitry and rear window defogger relay cannot be repaired. if
damaged or faulty, the entire heater and air conditioner control assembly must be replaced. Refer
to Heater-A/C Control in the Replacement.

Heated Glass Element: Testing and Inspection Detecting Breaks in Rear Window Defogger Grid
To detect breaks in the grid lines, the following procedure is required:
1. Turn the ignition switch to the On position. Set the defogger switch in the On position. The
indicator lamp should light. If OK, go to Step 3. If not
OK, see Rear window Defogger System Control in the Diagnosis and Testing.
2. Using a 12-volt DC voltmeter, contact the vertical bus bar on the right side of the vehicle with the
negative lead. With the positive lead, contact
the vertical bus bar on the left side of the vehicle. The voltmeter should read battery voltage. If OK,
go to Step 4. If not OK, repair the open circuit to the rear window defogger system control as
required.
3. With the negative lead of the voltmeter, contact a good body ground point. The voltage reading
should not change. If OK, go to Step 5. If not OK,
repair the circuit to ground as required.
4. Connect the negative lead of the voltmeter to the right side bus bar and touch each grid line at
midpoint C with the positive lead. A reading of
approximately six volts indicates a line is good. A reading of zero volts indicates a break in the grid
line between midpoint C and the left side bus bar. A reading of ten to fourteen volts indicates a
break between midpoint C and the right side bus bar. Move the positive lead on the grid line
towards the break and the voltage reading will change as soon as the break is crossed.

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
The operation of the electrically heated rear window defogger system can be confirmed in one of
the following manners:
1. Turn the ignition switch to the On position. While monitoring the instrument panel voltmeter, set
the defogger switch in the On position. When the
defogger switch is turned On, a distinct voltmeter needle deflection should be noted.
2. Turn the ignition switch to the On position. Set the defogger switch in the On position. The rear
window defogger operation can be checked by
feeling the rear window glass. A distinct difference in temperature between the grid lines and the
adjacent clear glass can be detected within three to four minutes of operation.
Rear Window Glass Grid Test
3. Using a 12-volt DC voltmeter, contact the rear glass heating grid terminal A (right side) with the
negative lead, and terminal B (left side) with the
positive lead. The voltmeter should read battery voltage.
The above checks will confirm system operation. Illumination of the defogger switch indicator lamp
means that there is electrical current available at the output of the rear window defogger logic and
timer circuitry, but does not confirm that the electrical current is reaching the rear glass heating grid
lines.
If the defogger system does not operate, the problem should be isolated in the following manner:
1. Confirm that the ignition switch is in the On position.

Rear Window Defogger System
2. Ensure that the rear glass heating grid feed and ground wires are connected to the glass.
Confirm that the ground wire has continuity to ground, and
that there is continuity between the electrical contacts in the rear door hinge pillar when the rear
door is closed.
3. Check the fuses in the Power Distribution Center (PDC) and in the junction block. The fuses
must be tight in their receptacles and all electrical
connections must be secure.
When the above steps have been completed and the rear glass heating grid is still inoperative, one
or more of the following is faulty:
- Defogger system control
- Rear window grid lines (all grid lines would have to be broken or one of the feed wires
disconnected for the entire system to be inoperative).
If setting the defogger switch to the On position produces a severe voltmeter deflection, check for a
short circuit between the rear window defogger system control output and the rear glass heating
grid.

Wiper Control Module: Description and Operation
SYSTEM OPERATION
Intermittent Wipe Module An intermittent wipe module is used on vehicles that are not equipped
with the optional Vehicle Theft Security System (VTSS). In addition to low and high speed, the
intermittent wipe system has a delay mode. Electronic circuitry within the intermittent wipe module
is used to accomplish the wiper delay mode. The delay time selected by the driver has a range of
from about one-half second to about fourteen seconds.
The driver selects the length of the delay by placing the wiper (multi-function) switch knob in one of
five different intermittent wipe detent positions. One of the detent positions sends a battery voltage
signal to the intermittent wipe module, while the other four positions use resistors to provide
progressively lower voltage signals to the module. If the washer knob is depressed while the wiper
switch is in the Off position, the intermittent wipe module will operate the wiper motor for
approximately two wipes and automatically turn off the motor.
The intermittent wipe module is snap-fit onto a single blade-type mounting bracket located on the
instrument panel reinforcement above the glove box opening. The intermittent wipe module cannot
be repaired and, if faulty or damaged, it must be replaced.

SYSTEM OPERATION
An intermittent wipe relay is used on models that are equipped with the optional Vehicle Theft
Security System (VTSS). The intermittent wipe relay is a International Standards Organization
(ISO) micro-relay. The terminal designations and functions are the same as a conventional ISO
relay. However, the micro-relay terminal orientation (or footprint) is different, current capacity is
lower, and the relay case dimensions are smaller than those of the conventional ISO relay.
The intermittent wipe relay is a electromechanical device that switches battery current to the
windshield wiper motor when the relay coil is grounded by the Central Timer Module (CTM) in
response to inputs from the windshield wiper (multi-function) switch. See Intermittent Wipe Relay in
the Diagnosis.
The intermittent wipe relay is located in a connector that is taped back to the instrument panel wire

about two seconds when the ignition switch is turned to the On position as a bulb test. After the
bulb test, the instrument cluster circuitry controls the lamp based upon a hard wired input from the
washer fluid level sensor.
The washer fluid level sensor uses a float in the washer fluid reservoir to monitor the fluid level.
The up and down action of the float opens or closes the switch within the washer fluid level sensor
that provides a ground signal to the instrument cluster circuitry.
If the instrument cluster circuitry senses a ground input from the washer fluid level sensor for more
than about sixty seconds, it turns on the low washer fluid warning lamp and sends a chime tone
request to the Central Timer Module (CTM). This helps to reduce the effects of fluid sloshing within
the reservoir. This lamp also latches. Once the lamp has been turned on, it will remain on until
washer fluid is added to the reservoir and the ignition switch is cycled.
Refer to Washer Fluid Level Sensor in Wiper and Washer Systems/Wiper and Washer Systems for
more information.

Windshield Washer Pump: Description and Operation
SYSTEM OPERATION
The washer pump and motor are mounted near the bottom of the washer reservoir. A barbed
nipple on the pump housing passes through a rubber grommet seal installed in a hole near the
bottom of the reservoir. The washer pump is retained by an interference fit between the barbed
pump nipple and the grommet seal, which is a light press fit.
A permanently lubricated and sealed motor is coupled to a rotor-type pump. Washer fluid is
gravity-fed from the reservoir to the pump. When the motor is energized, the pump pressurizes the
washer fluid and forces it through the plumbing to the nozzles.
The washer pump and motor unit cannot be repaired. If faulty, the entire washer pump and motor
unit must be replaced.

Wiper Arm: Description and Operation
SYSTEM OPERATION
All Ram van/wagon models have two 47.5-centimeter (19-inch) windshield wiper blades with
non-replaceable rubber elements (squeegees).
These wiper blades include an anti-lift feature. The wiper blades and squeegees must be oriented
correctly when installed on the wiper arms for the anti-lift feature to be effective. See Wiper Blade
in the Removal and Installation for more information.
Caution should be exercised to protect the rubber squeegees from any petroleum-based cleaners
or contaminants, which will rapidly deteriorate the rubber. If the squeegees are damaged, worn, or
contaminated, the entire wiper blade assembly must be replaced.
Wiper squeegees exposed to the elements for a long time tend to lose their wiping effectiveness.
Periodic cleaning of the squeegees is suggested to remove deposits of salt and road film. The
wiper blades, arms, and windshield should be cleaned with a sponge or cloth and windshield
washer fluid, a mild detergent, or a non-abrasive cleaner. If the squeegees continue to streak or
smear, the wiper blades should be replaced.
The blades are mounted to two spring-loaded wiper arms. The spring tension of the wiper arms
controls the pressure applied to the blades on the glass. The windshield wiper arms are secured by
an integral latch to the two wiper pivots on the cowl plenum cover/grille panel at the base of the
windshield.
The wiper arms and blades cannot be adjusted or repaired. If faulty or damaged, they must be

DISCUSSION:
Windshield wiper blades/elements are frequently replaced unnecessarily. Because of the
environmental conditions vehicles can be operated in, a film can build up on both the windshield
and the windshield wiper elements that will cause poor cleaning/streaking of the windshield, and in
some instances, a chattering condition as the wipers blades travel across the windshield.
Replacement of the wiper blades/elements is normally NOT required to correct streaking issues. A
simple NORMAL MAINTENANCE cleaning of the wiper blades/elements and windshield is all that
is required.
If the wipe pattern appears to be streaky or if there is chatter and no damage to the wiper
blades/elements is obvious, the following steps should be performed:
1. Use a soft cloth or sponge & squeegee and MOPAR Windshield Washer Solvent (p/n
04318067AB, 16 Oz. bottle or p/n 04318068AB, 32 Oz. bottle), MOPAR Glass Cleaner (p/n
04897623AB, 16 Oz. bottle) or a solution of 50/50 alcohol and water, to wash the windshield.
2. Raise the wiper blades off the glass and clean the wiper blade elements (rubber insert) with
MOPAR Windshield Washer Solvent or a solution of 50/50 alcohol and water and a soft cloth,
paper towel or sponge.
3. Return the wiper blades to their normal operating position and function the washer system. If the
wiper blades/elements are not streaking the windshield or chattering, replacing the blade
assembly(ies) is not necessary. If the wipe pattern is still objectionable, repeat step 2 several times.
If the wipe pattern is still objectionable, replace the wiper blades/elements.

Wiper Control Module: Description and Operation
SYSTEM OPERATION
Intermittent Wipe Module An intermittent wipe module is used on vehicles that are not equipped
with the optional Vehicle Theft Security System (VTSS). In addition to low and high speed, the
intermittent wipe system has a delay mode. Electronic circuitry within the intermittent wipe module
is used to accomplish the wiper delay mode. The delay time selected by the driver has a range of
from about one-half second to about fourteen seconds.
The driver selects the length of the delay by placing the wiper (multi-function) switch knob in one of
five different intermittent wipe detent positions. One of the detent positions sends a battery voltage
signal to the intermittent wipe module, while the other four positions use resistors to provide
progressively lower voltage signals to the module. If the washer knob is depressed while the wiper
switch is in the Off position, the intermittent wipe module will operate the wiper motor for
approximately two wipes and automatically turn off the motor.
The intermittent wipe module is snap-fit onto a single blade-type mounting bracket located on the
instrument panel reinforcement above the glove box opening. The intermittent wipe module cannot
be repaired and, if faulty or damaged, it must be replaced.

SYSTEM OPERATION
The wiper linkage and pivot module is secured with screws to the cowl top panel beneath the cowl
plenum cover/grille panel. The wiper motor is secured with screws on the engine compartment side
of the cowl plenum panel. The wiper motor output shaft and crank arm are installed through a hole
in the cowl plenum panel into the cowl plenum area, where they are connected to the wiper linkage.
The two wiper pivot crank arms and the wiper motor crank arm each have ball studs on their ends.
The ball stud on the driver side pivot crank arm is longer than the other two ball studs. A
connecting link with a plastic socket-type bushing in the passenger side end, and a plastic
sleeve-type bushing in the driver side end, is fit over the pivot crank arm ball studs to join the two
pivots.
The wiper drive link has a plastic socket-type bushing on each end. One end of the drive link is
snap-fit over the exposed end of the longer driver side pivot ball stud, while the other end is snap-fit
over the ball stud on the wiper motor crank arm.
The wiper linkage, pivots, and bushings are only serviced as a complete unit. If any part of this
assembly is faulty, the entire wiper linkage unit must be replaced. The wiper motor is serviced
separately.

Wiper Relay: Description and Operation
SYSTEM OPERATION
An intermittent wipe relay is used on models that are equipped with the optional Vehicle Theft
Security System (VTSS). The intermittent wipe relay is a International Standards Organization
(ISO) micro-relay. The terminal designations and functions are the same as a conventional ISO
relay. However, the micro-relay terminal orientation (or footprint) is different, current capacity is
lower, and the relay case dimensions are smaller than those of the conventional ISO relay.
The intermittent wipe relay is a electromechanical device that switches battery current to the
windshield wiper motor when the relay coil is grounded by the Central Timer Module (CTM) in
response to inputs from the windshield wiper (multi-function) switch. See Intermittent Wipe Relay in
the Diagnosis.
The intermittent wipe relay is located in a connector that is taped back to the instrument panel wire
harness above the inboard side of the glove box opening. The intermittent wipe relay cannot be
repaired and, if faulty or damaged, it must be replaced.
